Bacterial iron detoxification at the molecular level [Protein Structure and Folding]

Iron is an essential micronutrient, and, in the case of bacteria, its availability is commonly a growth-limiting factor. However, correct functioning of cells requires that the labile pool of chelatable “free” iron be tightly regulated. Correct metalation of proteins requiring iron as a cofactor demands that such a readily accessible source of iron exist, but overaccumulation results in an oxidative burden that, if unchecked, would lead to cell death. The toxicity of iron stems from its potential to catalyze formation of reactive oxygen species that, in addition to causing damage to biological molecules, can also lead to the formation of reactive nitrogen species. To avoid iron-mediated oxidative stress, bacteria utilize iron-dependent global regulators to sense the iron status of the cell and regulate the expression of proteins involved in the acquisition, storage, and efflux of iron accordingly. Here, we survey the current understanding of the structure and mechanism of the important members of each of these classes of protein. Diversity in the details of iron homeostasis mechanisms reflect the differing nutritional stresses resulting from the wide variety of ecological niches that bacteria inhabit. However, in this review, we seek to highlight the similarities of iron homeostasis between different bacteria, while acknowledging important variations. In this way, we hope to illustrate how bacteria have evolved common approaches to overcome the dual problems of the insolubility and potential toxicity of iron.

Humanin selectively prevents the activation of pro-apoptotic protein BID by sequestering it into fibers [Protein Structure and Folding]

Members of the B-cell lymphoma (BCL-2) protein family regulate mitochondrial outer membrane permeabilization (MOMP), a phenomenon in which mitochondria become porous and release death-propagating complexes during the early stages of apoptosis. Pro-apoptotic BCL-2 proteins oligomerize at the mitochondrial outer membrane during MOMP, inducing pore formation. Of current interest are endogenous factors that can inhibit pro-apoptotic BCL-2 mitochondrial outer membrane translocation and oligomerization. A mitochondrial-derived peptide, Humanin (HN), was reported being expressed from an alternate ORF in the mitochondrial genome and inhibiting apoptosis through interactions with the pro-apoptotic BCL-2 proteins. Specifically, it is known to complex with BAX and BID. We recently reported the fibrillation of HN and BAX into β-sheets. Here, we detail the fibrillation between HN and BID. These fibers were characterized using several spectroscopic techniques, protease fragmentation with mass analysis, and EM. Enhanced fibrillation rates were detected with rising temperatures or pH values and the presence of a detergent. BID fibers are similar to those produced using BAX; however, the structures differ in final conformations of the BCL-2 proteins. BID fibers display both types of secondary structure in the fiber, whereas BAX was converted entirely to β-sheets. The data show that two distinct segments of BID are incorporated into the fiber structure, whereas other portions of BID remain solvent-exposed and retain helical structure. Similar analyses show that anti-apoptotic BCL-xL does not form fibers with humanin. These results support a general mechanism of sequestration of pro-apoptotic BCL-2 proteins into fibers by HN to inhibit MOMP.

A combinatorial native MS and LC-MS/MS approach reveals high intrinsic phosphorylation of human Tau but minimal levels of other key modifications [Neurobiology]

Abnormal changes of neuronal Tau protein, such as phosphorylation and aggregation, are considered hallmarks of cognitive deficits in Alzheimer's disease. Abnormal phosphorylation is thought to precede aggregation and therefore to promote aggregation, but the nature and extent of phosphorylation remain ill-defined. Tau contains ∼85 potential phosphorylation sites, which can be phosphorylated by various kinases because the unfolded structure of Tau makes them accessible. However, methodological limitations (e.g. in MS of phosphopeptides, or antibodies against phosphoepitopes) led to conflicting results regarding the extent of Tau phosphorylation in cells. Here we present results from a new approach based on native MS of intact Tau expressed in eukaryotic cells (Sf9). The extent of phosphorylation is heterogeneous, up to ∼20 phosphates per molecule distributed over 51 sites. The medium phosphorylated fraction Pm showed overall occupancies of ∼8 Pi (± 5) with a bell-shaped distribution; the highly phosphorylated fraction Ph had 14 Pi (± 6). The distribution of sites was highly asymmetric (with 71% of all P-sites in the C-terminal half of Tau). All sites were on Ser or Thr residues, but none were on Tyr. Other known posttranslational modifications were near or below our detection limit (e.g. acetylation, ubiquitination). These findings suggest that normal cellular Tau shows a remarkably high extent of phosphorylation, whereas other modifications are nearly absent. This implies that abnormal phosphorylations at certain sites may not affect the extent of phosphorylation significantly and do not represent hyperphosphorylation. By implication, the pathological aggregation of Tau is not likely a consequence of high phosphorylation.

Structural transitions in Orb2 prion-like domain relevant for functional aggregation in memory consolidation [Molecular Biophysics]

The recent structural elucidation of ex vivo Drosophila Orb2 fibrils revealed a novel amyloid formed by interdigitated Gln and His residue side chains belonging to the prion-like domain. However, atomic-level details on the conformational transitions associated with memory consolidation remain unknown. Here, we have characterized the nascent conformation and dynamics of the prion-like domain (PLD) of Orb2A using a nonconventional liquid-state NMR spectroscopy strategy based on 13C detection to afford an essentially complete set of 13Cα, 13Cβ, 1Hα, and backbone 13CO and 15N assignments. At pH 4, where His residues are protonated, the PLD is disordered and flexible, except for a partially populated α-helix spanning residues 55–60, and binds RNA oligos, but not divalent cations. At pH 7, in contrast, His residues are predominantly neutral, and the Q/H segments adopt minor populations of helical structure, show decreased mobility and start to self-associate. At pH 7, the His residues do not bind RNA or Ca2+, but do bind Zn2+, which promotes further association. These findings represent a remarkable case of structural plasticity, based on which an updated model for Orb2A functional amyloidogenesis is suggested.

Role of phospholipid synthesis in the development and differentiation of malaria parasites in the blood [Microbiology]

The life cycle of malaria parasites in both their mammalian host and mosquito vector consists of multiple developmental stages that ensure proper replication and progeny survival. The transition between these stages is fueled by nutrients scavenged from the host and fed into specialized metabolic pathways of the parasite. One such pathway is used by Plasmodium falciparum, which causes the most severe form of human malaria, to synthesize its major phospholipids, phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine. Much is known about the enzymes involved in the synthesis of these phospholipids, and recent advances in genetic engineering, single-cell RNA-Seq analyses, and drug screening have provided new perspectives on the importance of some of these enzymes in parasite development and sexual differentiation and have identified targets for the development of new antimalarial drugs. This Minireview focuses on two phospholipid biosynthesis enzymes of P. falciparum that catalyze phosphoethanolamine transmethylation (PfPMT) and phosphatidylserine decarboxylation (PfPSD) during the blood stages of the parasite. We also discuss our current understanding of the biochemical, structural, and biological functions of these enzymes and highlight efforts to use them as antimalarial drug targets.

Lipid-tuned Zinc Transport Activity of Human ZnT8 Protein Correlates with Risk for Type-2 Diabetes [Molecular Bases of Disease]

Zinc is a critical element for insulin storage in the secretory granules of pancreatic beta cells. The islet-specific zinc transporter ZnT8 mediates granular sequestration of zinc ions. A genetic variant of human ZnT8 arising from a single nonsynonymous nucleotide change contributes to increased susceptibility to type-2 diabetes (T2D), but it remains unclear how the high risk variant (Arg-325), which is also a higher frequency (>50%) allele, is correlated with zinc transport activity. Here, we compared the activity of Arg-325 with that of a low risk ZnT8 variant (Trp-325). The Arg-325 variant was found to be more active than the Trp-325 form following induced expression in HEK293 cells. We further examined the functional consequences of changing lipid conditions to mimic the impact of lipid remodeling on ZnT8 activity during insulin granule biogenesis. Purified ZnT8 variants in proteoliposomes exhibited more than 4-fold functional tunability by the anionic phospholipids, lysophosphatidylcholine and cholesterol. Over a broad range of permissive lipid compositions, the Arg-325 variant consistently exhibited accelerated zinc transport kinetics versus the Trp-form. In agreement with the human genetic finding that rare loss-of-function mutations in ZnT8 are associated with reduced T2D risk, our results suggested that the common high risk Arg-325 variant is hyperactive, and thus may be targeted for inhibition to reduce T2D risk in the general populations.

Malawi’s Re-Run Election is Lesson for African Opposition

1 July 2020

Fergus Kell

Projects Assistant, Africa Programme
The overturning of the result in the fresh presidential contest sets a bold precedent for the continent, as a process built upon the resilience of democratic institutions and the collective spirit of opposition.

2020-07-01-Malawi-Chakwera-Election

Malawi is only the second African country to annul a presidential election, after Kenya in 2017. It is the first in which the opposition has won the re-run.

The initial May 2019 vote had narrowly returned incumbent Peter Mutharika to the presidency. But in February 2020 a landmark ruling by Malawi’s constitutional court annulled the result citing ‘widespread, systematic and grave’ irregularities, including the now-infamous use of corrective fluid in vote tallying, and the Malawi Electoral Commission’s (MEC) failure to address complaints before announcing results. New elections were ordered within 150 days.

In a decisive contrast with the previous year, the fresh polls on 23 June saw the coming together of Lazarus Chakwera of the Malawi Congress Party (MCP) and running mate Saulos Chilima of the United Transformation Movement (UTM) to head a coalition of nine opposition parties - having fiercely competed as the leading challengers previously.

The constitutional court ruling had also changed Malawi’s electoral system, replacing a first-past-the-post model with one demanding an outright majority, which further encouraged the regional power bases of Malawi’s opposition to cast ego aside and work in alliance with each other.

In tandem with a slick digital campaign, the new alliance travelled widely to hold rallies across what is one of the world’s youngest countries, while the elderly Mutharika remained largely confined to the capital. It would be a strategy that ultimately delivered Chakwera to the presidency, polling 58 per cent of votes to Mutharika’s 39.

Political opposition elsewhere in Africa should take note from Malawi’s coalition - dialogue, not division, can offer a genuine path to change, especially in those countries with less favourable institutional conditions. Neighbouring Zambia would certainly do well to heed this example ahead of a pivotal election of its own in 2021.

A victory built on institutional precedent

Yet the story here is not only about throwing out an incumbent: Malawians had already done so twice before, rejecting sitting presidents at the polls in 1994 and 2014. It is also not unfamiliar to see public opinion and the judiciary work in parallel to uphold the constitution: former president Bakili Muluzi was twice blocked from abolishing term limits by popular demonstration during his second term, and again prevented from running for a third time in 2009 by the constitutional court.

The new result did not arise as the foregone conclusion of a judicial miracle. Rather, throughout the re-run process Malawi has had to repeatedly draw upon the strength of its broad-based institutional foundations. The image of the constitutional court judges arriving to deliver their annulment verdict in February wearing bulletproof vests under their robes was a stark reminder that this was never the easy route to take.

In contrast to many other African states, Mutharika was unable to call upon military support as the Malawi Defence Forces (MDF) had moved to shield protesting citizens and protect the judiciary since the 2019 election. The MDF also had previous form in this respect, having defended then-vice president Joyce Banda’s constitutional right to assume the presidency after the incumbent’s death in 2012.

And this institutional resilience from the army would facilitate a smooth and mostly peaceful election process during the re-run, despite Mutharika attempts to intervene by replacing the MDF’s commander and his deputy in March 2020.

Just ten days before the fresh vote the Mutharika government switched focus back to the country’s legal system by attempting to enforce the premature retirement of Malawi’s chief justice, only to be blocked by the high court. Even as unofficial tallies trickled in, Mutharika’s Democratic Progressive Party (DPP) demanded the MEC annul the result: claiming their monitors were intimidated in MCP strongholds, and requesting unlawful access to scrutinise null and void votes.

Headed by a new chairperson, this time the MEC displayed enormous patience in the verification process and openly tackled complaints, now mainly from the DPP. On social media, Malawians celebrated the contrast between images of tally sheets from 2019 and the re-run.

Writing a new chapter

There are lessons here too for international partners. UK diplomacy played a subtle role in encouraging Mutharika to accept the legal process - he was invited to appear at the UK-Africa Investment Summit in January - while also helping promoting early dialogue among opposition parties.

At a time of pressure for UK engagement to offer clear strategic value, the impact of less easily quantifiable forms of influence should not be overlooked, especially as international observer missions effectively went missing in the discredited 2019 election. Preliminary statements back then from the Commonwealth, European Union, African Union and Southern African Development Community (SADC) struck a mostly congratulatory tone and were non-committal on the issues that would prove decisive in the court ruling. None went on to release their final reports.

Malawi must now start to move beyond election mode. Though COVID-19 cases remain low by global standards, a budget already heavily dependent on foreign aid and hampered by 18 months of political uncertainty will be slashed further by the pandemic’s impact. The IMF has predicted GDP growth of just 1% in 2020, down from a pre-coronavirus projection of 5%.

As it inherits a major balance of payments crisis, mounting debt and with no tourism revenue to fall back on, the new government will need to use its political capital to push for immediate reform. But it must not forget the core tenet of its campaign. The coalition that defeated Mutharika united the MCP’s rural support base with the middle-class urban following of the UTM. This spirit of unity and inclusion must be expanded and focus on long-term recovery. On this undertaking – unlike the polls – there will be no opportunity for a re-run.

UK Should Focus on Better Defining Objectives in the Sahel

22 July 2020

Dr Alex Vines OBE

Managing Director, Ethics, Risk & Resilience; Director, Africa Programme
The Sahel is one of Africa’s poorest and most fragile regions witnessing an escalation in jihadist activity and illegal migration, writes Alex Vines.

The UK has been redeploying diplomatic, defence and development capabilities towards the Sahel since 2018 – a strategic pivot intended to deliver development impact, address long term security threats to UK interests and support alliances with international partners.

The Sahel is one of Africa’s poorest and most fragile regions and has witnessed an escalation in jihadist activity, illegal migration and trafficking since a security crisis erupted in Mali in 2012.

The crisis spread to Niger and Burkina Faso and may now spill over into Côte d’Ivoire, Ghana and Senegal. With Nigeria also facing insurgency in the Lake Chad basin, all major regional security and economic anchors in the region are under threat including key UK partners. 

Reviewing the Sahel pivot

This pivot has already resulted in the expanding of UK embassies in Senegal, Mauritania and Mali and public commitments to opening new ones in Chad and Niger.

Back in London, there has also been a large uplift of staff including the setting up of a cross-Whitehall Joint Sahel Department in late 2018 and plans for more UK civil servants to have placements with the French government on the Sahel.

Yet in light of looming economic shocks from Brexit and Covid-19, there has been a lively debate in Whitehall on whether this is stretching UK resources too thin in an area of Africa that does not have close ties with the UK.

UK ministers are this week reviewing the Sahel pivot and will decide if it continues or grinds to a standstill including whether full embassies are opened in Niger and Chad.

This debate is not new. The UK has opened and closed its diplomatic missions in the Sahel in fits and starts since the early 1960s. More recently, MI6 pushed the re-opening of the embassy in Bamako in 2010 foreseeing Mali’s fragility before the current crisis started.

Partnering with the French

But though the Sahel is likely to dominate the Africa peace and security agenda for decades to come, the UK’s serious engagement in the region is not just about strategic foresight.

It also fulfils two other objectives: of partnership with two key bilateral allies, particularly France, and authority and leverage in multilateral fora such as the United Nations, African Union and the EU.

Partnering with the French in the Sahel has become even more important due to Brexit and the need to reinforce relationships with key European partners.

In 2012, David Cameron concluded that the rapid French response to stop a jihadist advance on the Malian capital Bamako was 'in our interests' and authorized the deployment of 330 UK military personnel, two cargo aircraft and a surveillance plane.

In July 2018, the UK announced further support to French led Opération Barkhane sending three Royal Air Force Chinook helicopters – supported by almost 100 personnel  which remain in theatre to this day.

UN commitment

Demonstrating the UK’s commitment to UN peacekeeping has also resulted in the deployment of 250 troops to join a UN peacekeeping mission to Mali later this year.

Based in Gao, these troops will form a long-range reconnaissance capability providing threat awareness, contributing to the protection of civilians and helping to prevent conflict from spilling over to neighbouring states.

This represents one of the biggest British peacekeeping deployments since Bosnia and it will be the most dangerous mission for British forces since Afghanistan.

The UK is also one of the largest humanitarian donors to the region and has contributed over £500 million in bilateral development and humanitarian assistance since 2015.

With COVID-19 now an additional challenge in the Sahel, a significant part of the UK’s £764 million contribution to the global COVID-19 effort will be channelled to the region.

New embassies are 'global Britain' strategy pillars

Keeping an eye on the impact of these initiatives requires a meaningful UK diplomatic network on the ground.

New embassies in the Sahel cost a fraction of maintaining three Chinook helicopters in the region providing the government real time insight in the post-Brexit absence of a regular supply of country analysis from the European External Action Service and support for the UK’s international relationships.

It also underlines the UK’s commitment to UN peacekeeping and standing as a permanent member of the UN Security Council in light of regular discussions of the Sahel.

The tripartite ministerial review of the Sahel pivot by the secretaries of state for foreign affairs, international development and defence that is underway should not penny pinch by reversing the opening of small embassies in Niger and Chad nor threaten the overall strategic focus on the Sahel – most recently welcomed by the House of Lord’s Select Committee on International Relations and Defence in its July report on UK Africa policy.

Instead, UK ministers should focus on better defining what the UK’s specific objectives are in the Sahel and particularly what the UK plans to do about Burkina Faso whose rapidly deteriorating security threatens to over-spill into key UK partner Ghana.

Elections in Côte d’Ivoire: President Ouattara’s Dilemma

28 July 2020

Paul Melly

Consulting Fellow, Africa Programme
After the sudden death of Côte d’Ivoire’s Prime Minister Amadou Gon Coulibaly, President Ouattara is now deciding whether to stand for a third term. However, such a move would face challenges internationally, and particularly in West Africa.

Gon Coulibaly, an economic technocrat and Ouattara loyalist since the 1990s, was earmarked in March as the candidate for the ruling Rassemblement des Houphouëtistes pour la Démocratie et la Paix (RHDP) party in the elections due in October, and represented a handpicked heir, trusted to sustain the strategy established during Ouattara’s nine years in power.

Many RDHP parliamentarians and local mayors are now pressing the 78-year-old Ouattara to run again. This was not what he had planned. He hoped to go out on a high – ‘par la grande porte’ – and set a statesmanlike example of retirement by choice, making way for the next generation. His leadership of reform of the regional currency that will see the end of the West African CFA franc would have been the crowning achievement of a presidency that had taken his country from post-war stagnation to sustained growth GDP growth rates around seven per cent before COVID-19 forced a slowdown, as it has worldwide.

A profound strategic dilemma

Gon Coulibaly had undergone a heart transplant in 2012, and when he hurried to Paris in early May and was fitted with a stent, some wondered whether he would have the energy required for an election campaign. Yet he returned home on 2 July, with his formal nomination by the RHDP pencilled in for early the next month. His sudden death on 8 July, at the age of just 61, was a terrible personal blow for Ouattara, who had regarded him almost as a son, and much more than a purely political protégé. But it also left the president facing a profound strategic dilemma.

Names of alternative potential RHDP candidates have been floated – notably the defence minister, and now interim premier, Hamed Bakayoko and the secretary general of the presidency Patrick Achi. Both have solid electoral track records and ample experience of government. But over recent days the impression has grown that they do not command the ultimate confidence of Alassane Ouattara to take on the leadership of the nation.

Speculation has grown that the president will conclude that he has no choice but to go back on his promise to retire and stand for yet another term. Although some respected legal experts disagree, he has always made a point of insisting that the constitutional reform of 2016 allows him to run again. And many influential voices within the RHDP are now pressing him to do so.

This is not ‘rentacrowd’ fawning. Many members of the governing party have always felt that Ouattara offers the strongest blend of political appeal, governing capability and international profile required to lead a country that likes to see itself as West Africa’s ‘elephant’.

A weak opposition, but third term challenges

In electoral terms, Ouattara’s greatest campaign asset might be the unconvincing state of the opposition figures who are actually free to stand, after the Ivorian authorities’ strong-armed the judicial system into blocking the hopes of the of the smooth-talking former parliamentary speaker Guillame Soro, who had great appeal for Cote D’Ivoire’s growing young population. Soro is now exiled in France after conviction in absentia for corruption. Ex-president Laurent Gbagbo remains in Brussels, while the International Criminal Court considers the prosecution appeal against his acquittal on charges of human rights crimes. He is now allowed to travel and has applied for a passport to come home, but it is unclear if this will be granted. That leaves another former head of state, the 86-year old Henri Konan Bédié, as the main opposition challenger.

However, even if the RHDP party machine delivers victory for Ouattara, a third term risks hard questions from those who dispute its legitimacy and it may generate other significant political challenges too. Some 60 per cent of Ivorians are under the age of 25, and many young people are impatient for leaders more in tune with their concerns and outlook. Some 51 per cent now live in towns and cities.

The sprawling Abidjan conurbation, in particular, weighs heavily in the political culture and national mood. Street protest and urban frustrations are a real factor, and something that fuels vocal grassroots support for both the Soro and Gbagbo camps.

Moreover, despite the government’s capable management, the COVID-19 crisis has struck a severe economic and social blow that is sure to impose painful legacy pressures. Even when real GDP was rising by seven per cent per annum, increasingly evident inequality was brewing popular resentment. Corruption appeared to be on the rise, and the obvious prosperity, construction and consumption in parts of Abidjan were not reflected nationwide nor in all sections of society.

In the latter years of his second term, Ouattara recognized this and launched an ambitious programme to broaden the reach of development and nudge growth towards a more ‘inclusive’ model. But selling this as the core of an election agenda would be harder for a political veteran who has been in power since 2011 and who now went back on his rhetoric about making way for a younger generation.

A third term Ouattara would also face challenges internationally, and particularly in West Africa. He has always presented himself as a statesmanlike figure with restraint and respect for institutional values, setting a tone that has helped in the management of numerous regional crises – exemplified by his participation in a five-president mission to Bamako last week, an effort to broker a solution to Mali’s political and protest deadlock. If a third term run sparks mass domestic protest or accusations of constitutional manipulation, the diplomatic standing and influence so associated with Ouattara will be jeopardized.

So Côte d’Ivoire’s president faces profoundly awkward questions as he ponders the third term bid that he had forsworn less than five months ago. And yet he may well conclude that, from his political perspective, there is no viable alternative.

Why the Corrupt President of Belarus Deserves Sanctions

10 August 2020

Robert Bosch Stiftung Academy Fellow, Russia and Eurasia Programme
Sanctions would be a wake-up call for those who oversaw this brutal and dirty election campaign.

Belarusian president Aliaksandr Lukashenka deserves sanctions. This election campaign in Belarus, which culminated in a vote on Sunday is the most brutal and dirty in its history. But, so far, the EU, the UK and the US have only issued familiar-sounding and futile appeals to the Belarusian authorities condemning their actions. Not imposing sanctions is a de facto licence to continue with repression.

Despite all this, the West is unlikely to impose significant sanctions afterwards. There are several questionable reasons for this. First, Western policymakers fear sanctions against Lukashenko will make him more likely to genuflect to Russia. However, relations with Russia have already deteriorated as Belarus accuses Russia of trying to interfere with its domestic affairs.

Sanctions serve as a wake-up call. The Belarusian authorities then might seek - once again - to repair relations with the West and reduce repression for greater assistance in any direct confrontation with Russia.

Second, the West is reluctant to implement sanctions because it has already invested somewhat in warming relations with Belarusian authorities. Punishing Lukashenko could mean burying the - admittedly modest - achievements of a Belarus-West dialogue that started in 2014 after the conflict in Ukraine began.

Even US secretary of state Mike Pompeo met with Lukashenko in Minsk this year, after which Belarus replaced a small but symbolic amount of Russian oil for American. All the same, the West has its conscience to answer to if dialogue is won but repressions continue.

The third reason why the West may not resort to targeted economic sanctions and visa restrictions is a latent concern whether such measures have any effect on democratization processes at all. They may be appropriate punishment, but there is little evidence they ever change the nature of a regime.

According to this logic, if the West imposes sanctions, the Belarusian authorities will continue to crack down with repression because they will have nothing to lose. That said, in previous years, the Belarusian authorities have released political prisoners in response to sticks and carrots brandished by the West. If Belarusian political prisoners did not have a price tag, the authorities would most likely keep everyone in jail.

To be fair, there are reasonable arguments in favour of and against sanctions. But if the West fails to impose them - be it through lack of political will or out of genuine concern about their effectiveness - at least it should focus on helping ordinary Belarusians withstand Lukashenko’s repressions. After the vote, arrested and jailed Belarusian citizens might lack money for lawyers and arbitrarily imposed fines.

If repression spreads further, independent media and human rights organizations will need funds to keep their structures running in the heat of the crackdown. Many entrepreneurs might lose their companies for openly supporting free elections. Thus, if the West will not sanction Lukashenko, it should at least show solidarity with these Belarusians in peril.

Belarus Policy: Time to Play Hardball

12 August 2020

James Nixey

Director, Russia-Eurasia and Europe Programmes
Predictably, Aliaksandr Lukashenka’s regime has betrayed its people and the West’s trust yet again. A new, tougher approach is now the only option, and sanctions are only one of several actions that should be taken.

2020-08-12-Belarus-Protest-Election-Women

Aliaksandr Lukashenka’s 26-year rule — one of the world’s longest — is itself testament to his regime’s unwillingness to change. Most of Belarus’s immediate neighbours — particularly Lithuania, Latvia, and Poland — are far more prosperous. Now, with the farce of last week’s vote and the subsequent renewed violence that Minsk is willing to use on its citizens, Belarus finds itself at the very bottom of the post-Soviet legitimacy league table. But others share a portion of blame for this saga. The West — and the EU in particular — have failed the people of Belarus.

Russia — as ever in its relationships with the Soviet Union’s other successor states — has much to answer for. Like a drug pusher, it made a loss-leading investment in getting Belarus hooked on subsidised energy with meaningless security guarantees thrown in. Lukashenka may not have been the most compliant of post-Soviet leaders — especially recently — but he is still preferred by the Kremlin over any other potential contender, especially the reforming ones currently at the fore. ‘A son-of-a-bitch, but our son-of-a-bitch’ is Russia’s take.

But if Russia is the pusher, Western countries have been the enablers. Lukashenka has played them — and played them off against Russia — by frequently rejecting the offers of one and getting closer to the other, then switching and doing the same. The inability or unwillingness to recognize — and act on — evidence of the regime’s insincerity and its propensity to inflict harm on its own citizens has encouraged Minsk’s worst excesses. At the time of writing, more than 3,000 are reported to have been arrested and many tortured.

The EU bears special responsibility for this enabling. Ever since Belarus’s independence almost 30 years ago, it has offered plenty of carrots but few meaningful sticks. President of the European Commission Ursula von der Leyen said that ‘harassment & violent repression of peaceful protesters has no place in Europe’, but statements alone are inadequate. The Belarusian people are risking their freedoms and their lives on the streets of Minsk while the EU simply ‘calls on’ the Belarusian authorities to respect the democratic process.

Never too late

There is plenty that can be done. Sanctions are a much-touted first step and they have been proven to change the calculus, if not the character, of a regime. The EU, the UK and the US should act decisively and in unison to impose them immediately. Included in this would be the immediate halting of direct EU support to state entities.

But — as with Russia — it is lazy to limit responses to sanctions alone. Expulsion from international groups and values-based organizations should also be expedited. The EU’s Eastern Partnership (EaP) project with Belarus and five other countries is a prime example of supposedly conditional offers of financial assistance having been accepted, claimed and then defaulted on, time and again. It is time to make an example of Belarus and expel it from the EaP since it is abundantly clear it has no intention of adopting the values demanded of it.

The OSCE (Organization for Security and Co-operation in Europe) was invited by the Belarusian authorities too late to observe last Sunday’s vote-rigging, so why, in the face of such obvious obstruction, is Belarus even a member? The OSCE often claims its strength is its inclusivity, but this has rarely stood up to scrutiny. Inclusivity may have advantages, but one should also acknowledge its propensity to dilute effectiveness. Belarus should be expelled from here too.

The same goes for the IMF, the World Bank group, and its WTO observer status. It is time to make an example of this regime.

There should be less diplomatic nicety. It is natural that foreign service officials are hard-wired to want to make things better through their undoubted skills of sensitivity and tact, and sometimes this is the right answer. But not always. It would be better in some instances, such as this one, to give a tougher message — making it clear this regime is no longer seen as legitimate and that, where possible, western countries will seek relationships with more representative figures. This is neither easy nor especially pleasant, but it is not the same as breaking off diplomatic relations entirely, which is not wise as sometimes the organs of power must be dealt with.

And in terms of immediate practical help, the EU has an obligation to open its borders to Belarusian refugees who will surely come its way as conditions deteriorate. Lithuania is already showing the way in this regard.

Belarus is not one of the more difficult countries. It has no influence, no natural resources and therefore no leverage. It could resort to even more brutal repression of its citizens, but it should be made clear that such a desperate move by the authorities would entail even greater sanction. A common argument against a tougher approach is that it will drive Belarus into the arms of Russia. But this is to fall into the same trap — blackmail in reality — that we have seen for 20 years. In fact, it would be a good litmus test for a similar policy towards other ‘abuser countries’, such as Hungary.

Russia is certainly watching closely right now, and the last thing it wants is another colour revolution. The probability is that it will get this wish for now, as the demonstrations will surely cool off and key opposition figures not already in jail have been forced to flee. But western quiescence, as it always does, encourages Russia to act with further impunity. No invasion needed this time though if it already has most of what it wants — Union State notwithstanding — and the West stands aside.

A Chinese proverb maintains that ‘the best time to plant a tree was 20 years ago. The second-best time is now’. This holds true for dealing with Belarus. It is not too late to act decisively and play hardball. In doing so, the EU would help repair its reputation for hand-wringing and the people of Belarus might look at the EU with a respect they have lost.

Watching Belarus Means Watching Russia Too

13 August 2020

Protesters in Belarus face a dilemma, as being too successful in confronting the Belarusian regime could mean they end up having to reckon with Russian forces as well.

Amid outrage and revulsion at Belarus’s fraudulent election and the subsequent savage repression of protests, Western responses must be planned with half an eye on Russia. Not just for what is often described as the risk of ‘driving Belarus into Russia’s arms’ but also for the danger of unilateral Russian action, with or without Belarusian acquiescence.

In the past six years, there have been endless discussions of what might prompt another Russian military intervention in Europe after Ukraine. In many of these scenarios, it is precisely the situation currently unfolding in Belarus that has been top of the list, with all the wide-ranging implications for security of the continent as a whole that would follow.

Just as with Ukraine, Russia is considered likely to intervene if it seemed to Moscow there was a danger of ‘losing’ Belarus to the West. If the situation in Belarus becomes more unstable and unpredictable, assertive Russian action could aim to assert control by different possible means - either propping up Lukashenka as a paper-thin proxy for Russian power, or installing a different, more compliant leadership as a pretence at legitimacy.

New facts on the ground

Leadership and support for a Western response to events in Belarus might previously have been expected from the United States which, like the UK, had been actively pushing forward relations with Belarus. But besides its preoccupation with internal affairs, US criticism of the election and ‘detentions of peaceful protesters and journalists’ looks tenuous in the light of the current administration’s behaviour over its own recent domestic issues.

Nevertheless, for NATO and for the United States as its primary guarantor, what happens in Belarus remains critically important precisely because of the possible response by Russia. Unpredictability increases the risk of Russia declaring it has received a ‘request for assistance from the legitimate government of Belarus’ and moving military forces into the country.

Once the immediate challenge of suppressing dissent had been dealt with, the presence of Russian forces in Belarus – along with the air and missile forces they could be expected to bring with them - would substantially alter the security situation for a wide area of central Europe. Popular scenarios for Russian military adventures such as a move on the Suwałki gap - the strip of Polish-Lithuanian border separating the exclave of Kaliningrad from the rest of Russia - would no longer be several geopolitical steps away.

Ukraine would be forced to rapidly re-orient its defence posture to face a new threat from the north, while Belarus’s other neighbours would need to adjust to having effectively a direct border with Russia. In particular, NATO’s enhanced forward presence (eFP) contingents in Poland and Lithuania would become the focus of intense political attention, facing calls both for their rapid expansion, and their complete removal as destabilizing factors.

Examining Russia's options

NATO and the US’s European Command must now be watching Russia just as intently as Russia is watching Belarus. For now, Russia may be reassured by what it has seen. While the protests in Belarus are far more widespread than those in Ukraine which led to its former president Viktor Yanukovych fleeing the country, Aliaksandr Lukashenka is showing no signs of similarly losing his nerve.

The viciousness of the repression combined with more or less effective suppression of communications over the internet may mean unrest will soon be subdued. Even if there were a transfer of power, the current Belarusian opposition has not declared a policy of greater integration with the West - and Russia might feel it could constrain the options available to any replacement as effectively as it has done Lukashenka’s.

Perversely, continued international apathy could even work to Belarus’s benefit by providing reassurance to Russia. If a palpable lack of interest helps the Kremlin believe the discontent in Belarus is purely organic and spontaneous, and is not other countries ‘mobilizing the protest potential of the population’ in order to bring about a ‘colour revolution’, this would be a strong argument against a need to act in order to head off Western encroachment.

But the options facing ordinary Belarusians do remain bleak. Passivity means acceptance of continuing stagnation under Lukashenka, with his rule extended indefinitely. Active opposition means a very real risk of arrest with the possibility of serious injury. Unsuccessful protest means the cause may once again soon be forgotten by the outside world. Successful protest carries the ever-present risk of Russia stepping in with an offer of ‘fraternal assistance’ and Belarus becoming effectively a province of Russia rather than an independent country with – in the long term - the opportunity to choose its own future.

Conflict-Related Sexual Violence in Ukraine: An Opportunity for Gender-Sensitive Policymaking?

18 August 2020

Kateryna Busol

Robert Bosch Stiftung Academy Fellow, Russia and Eurasia Programme
Meaningful change is needed in Ukraine’s response to the conflict-related sexual violence, which affects both women and men.

The virus of violence

According to the UN (para. 7) and the International Criminal Court (ICC, para. 279), conflict-related sexual violence (CRSV) is quite prevalent in hostilities-affected eastern Ukraine. Both sexes are subjected to sexualized torture, rape, forced nudity, prolonged detention in unsanitary conditions with members of the other sex and threats of sexual violence towards detainees or their relatives to force confessions. Men are castrated. Women additionally suffer from sexual slavery, enforced and survival prostitution, and other forms of sexual abuse. Women are more exposed to CRSV: in the hostilities-affected area, every third woman has experienced or witnessed CRSV as opposed to every fourth man.

COVID-19 has redirected funding priorities, affecting the availability of medical and psychological help for CRSV survivors worldwide. In Ukraine, the very reporting of such violence, stigmatized even before the pandemic, has been further undermined by the country-wide quarantine-induced restrictions on movement and the closure of checkpoints between the government-controlled and temporarily uncontrolled areas.

Addressing CRSV in Ukraine

The stigma of CRSV, the patchy domestic legislation, and the unpreparedness of the criminal justice system to deal with such cases prevent the authorities from properly helping those harmed in the ongoing Russia-Ukraine armed conflict.

CRSV is equally traumatizing yet different in nuance for men and women. Female victims often choose not to report the violence. Women avoid protracted proceedings likely to cause re-traumatization and the disclosure of their experience, which could be particularly excruciating in small communities where everybody knows everyone.

Men also struggle to provide their accounts of CRSV. Their suppressed pain and shame of genital mutilation and other CRSV result in sexual and other health disfunctions. Combined with the post-conflict mental health struggles, this has been shown to lead to increased domestic violence and even suicide.

The very investigation of CRSV in Ukraine is challenging. Certain tests and examinations need to be done straight after an assault, which in the context of detention and grey zones of hostilities is often impossible. Specialized medical and psychological support is lacking. Investigators and prosecutors are hardly trained to deal with CRSV to the point that they do not ask questions about it during the interviews. Burdened by trauma and stigma, survivors are inclined to report torture or inhuman treatment, but not the sexualized aspects thereof.

Seven years into the conflict, the state still has not criminalized the full spectrum of CRSV in its domestic law. Ukraine’s Criminal Code contains a brief list of the violations of the rules and customs of warfare in article 438. It prohibits the inhuman treatment of civilians and POWs but does not list any types of CRSV.

The article has an open-ended reference to Ukraine’s ratified international treaties, from which the responsibility for other armed conflict violations may be derived. For the more detailed norms on CRSV, Ukraine should refer at least to Geneva Convention IV protecting civilians and two additional protocols to the Geneva Conventions, to which it is a party.

However, the novelty of the war context for Ukrainian investigators, prosecutors and judges and their overcautiousness about the direct application of international conventions mean that in practice, observing the treaty or jurisprudential instruction on CRSV has been slow.

Use of the Criminal Code’s articles on sexual violence not related to an armed conflict is not viable. Such provisions fail to reflect the horrible variety and complexity of CRSV committed in hostilities. They also envisage lesser punishment than a war crime of sexual violence would entail. Cumulatively, this fails to account for the intention of a perpetrator, the gravity of the crime and the trauma of its victims.

The lack of public debate and state action on CRSV understates its magnitude. Ukraine should break its silence about CRSV in Donbas and make addressing this violence part of its actionable agenda - in law and in implementation.

Ukraine should incorporate all war crimes and crimes against humanity of CRSV in its domestic legislation; ensure a more gendered psychological and medical support for both sexes; establish rehabilitation and compensation programmes for CRSV survivors; create special victims and witness protection schemes; consider the different stigmatizing effects of CRSV on men and women in criminal proceedings and engage the professionals of the same sex as the victim; map CRSV in the bigger picture of other crimes in Donbas to better understand the motives of the perpetrators; submit more information about CRSV to the ICC and educate the public to destigmatize the CRSV survivors.

The drafters of Ukraine’s transitional justice roadmap should ensure that it highlights CRSV, adopts a gendered approach to it and endorses female participation as a crucial component of reconciliation and broader policymaking.

Embracive policymaking

Although ‘the discriminatory line almost inevitably hurts women,’ 'every gender discrimination is a two-edged sword’, Ruth Bader Ginsburg famously argued before the US Supreme Court. This could not be more relevant for Ukraine. The conflict - and lockdown-related violence has reverberated deeper within Ukrainian society, raising fundamental questions about the roles of both sexes and gender equality.

The failure to address CRSV and its different stigmas for both sexes mirrors the general lack of sustainable gender lenses in Ukraine's policymaking. It is no coincidence that a June 2020 proposal for gender parity in political parties coincided with another spike of sexist remarks by top officials. While women get access to more positions in the army, sexual harassment in the military is investigated slowly. Despite all the impressive female professionals, no woman made it to the first four-member consultative civic group in the Minsk process. Such lack of diversity sends an unfortunate message that women are not important for Ukraine’s peace process.

Ginsburg said, ‘women belong in all places where decisions are being made.’ CRSV against either sex won’t be addressed properly until both sexes contribute with their talents and their grievances to all pillars of Ukraine’s state governance and strategy. Ukraine should look to engage professional women - and there are plenty - to join its public service not just in numbers, but as the indispensable equal voices of a powerful choir.

Can the International Criminal Court Help Belarus?

26 August 2020

Kateryna Busol

Robert Bosch Stiftung Academy Fellow, Russia and Eurasia Programme
A referral of election violence in Belarus to the International Criminal Court could enhance the support for the Belarusian people at other crucial platforms.

2020-08-26-belarus-icc.jpg

Making the case

The recent election results in Belarus have triggered revolution in yet another post-Soviet country and Aliaksandr Lukashenka’s response has been devastatingly brutal. However, the Belarusian people’s resilience and Western sanctionsadopted on 14 August – have proved effective. As some of the 6,700 jailed protesters were released, accounts of horrific treatment by law enforcement emerged: overcrowded cells, no food, torture, forced confessions, severe beatings , and threats of rape.

With reports of mounting violence, Polish MEP Radosław Sikorski warned Lukashenka to expect not just sanctions but also the possible intervention of the International Criminal Court (ICC), an idea supported by the opposition-led Belarus’ National Salvation. While there are significant impediments to the Court’s involvement, the impact of such an initiative could be ground-breaking.

Legal framework

The ICC considers criminal responsibility of top civilian or military leaders for only the most serious atrocities - war crimes, genocide, crimes against humanity and, in certain cases, the crime of aggression. In the context of Belarus, the Court’s jurisdiction over crimes against humanity might be relevant. According to the Rome Statute, the ICC’s founding treaty, crimes against humanity include widespread or systematic abuses directed against a civilian population. Atrocities relevant to Belarus include arbitrary imprisonment, torture, inhuman treatment, sexual violence, and enforced disappearances.

The ICC is a last resort. It can intervene only if states are unable or unwilling to properly investigate and prosecute serious crimes themselves. Although Belarus’s Criminal Code punishes crimes against humanity, as Lukashenka himself is implicated, impartial trials in the country are impossible while he is still in power. Other countries may investigate specific atrocities in Belarus under the universal jurisdiction principle. Universal jurisdiction greenlights investigations into the most serious crimes regardless of where they are perpetrated. German, Swedish and French proceedings on Syria are illustrative examples of this. Protesters may also file individual complaints of abuse to UN bodies under the protocols of the International Covenant on Civil and Political Rights and the Convention on the Elimination of All Forms of Discrimination against Women. The European Court of Human Rights is not an option for the protesters because Belarus is not a member of the Council of Europe.

As the UN mechanisms are yet to be triggered and there has not yet been any talk of universal jurisdiction proceedings, the question of recourse to the ICC remains. But as Belarus is not party to the Rome Statute, the only way to trigger the Court’s jurisdiction is a referral by the UN Security Council (UNSC). Even though it would be vetoed by Russia –  and, almost certainly, China – it could be worth pursuing.

The importance of symbolism

So far, the UNSC has referred to the ICC two situations in non-party states – Sudan and Libya. But for cases that do not end up being referred to the Court, the UNSC debates are as significant for what they manage to agree upon as they are for what they do not. Regarding Belarus, two impeded UNSC accountability initiatives are relevant: on Syria and MH17.

In 2014, Russia and China vetoed the referral of cases of violence in Syria to the ICC. In 2015, Russia was the only country to block the creation by the UNSC of a special tribunal to investigate Malaysian Airlines flight MH17, downed by a Russian missile over war-affected eastern Ukraine. In both cases, the vetoes delayed justice, but they did not prevent it. For Syria, special independent mechanisms to collect evidence for adjudication were developed. Although justice has yet to be done, except in states like Germany, the evidence is ready for any future court. For MH17, a proceeding at a domestic Dutch court became an alternative. Parallel to that, new evidence of Russia’s role in both Syria and the downing of MH17 emerged - contextualising its UNSC vetoes.

Russia’s stakes in the Belarusian elections are probably even higher: the victory of democracy in Belarus will deprive it of one of its closest and most dependent post-Soviet allies.

Even if Russia destroys any chance of Belarusian citizens using the ICC, the attempted ICC-Belarus discussion will not have been in vain. Russia’s opposition to the respective UNSC resolution would be a self-defeating validation of Lukashenka’s atrocities against his own people, unashamedly restated at one of the world’s top diplomatic negotiation tables. Similar to Syria and MH17, the UNSC would reconfirm its self-imposed impotency to defend basic human rights amid political conjuncture. This would bring more attention to the issue and catalyse action through other platforms, including the discussions across UN bodies and the consideration of Belarusians’ individual complaints of abuse, and could lead to tougher sanctions. It could also further make the case for universal jurisdiction proceedings in other countries.      

Supporting civil society

Belarusian civil society will need stronger support from democratic governments and human rights organizations in reporting and documenting the crimes. Other countries, neighbouring states in particular, should be ready to welcome Belarusian protesters through refugee schemes, so they are able to continue their activities from abroad.

When nationwide strikes enveloped Belarus, singers from the Minsk Opera supported protesters by singing Va, pensiero, the famed chorus of the Hebrew slaves from Verdi’s Nabucco – and a symbol of united Italy’s revival. The people of Belarus also want to live in a democratic state ‘where the mind is without fear and the head is held high’. And they deserve all the support they can get. The inevitable fall of Lukashenka’s regime might take time but it should not take more lives.

Rage Against the Algorithm: the Risks of Overestimating Military Artificial Intelligence

27 August 2020

Yasmin Afina

Research Assistant, International Security Programme
Increasing dependency on artificial intelligence (AI) for military technologies is inevitable and efforts to develop these technologies to use in the battlefield is proceeding apace, however, developers and end-users must ensure the reliability of these technologies, writes Yasmin Afina.

AI holds the potential to replace humans for tactical tasks in military operations beyond current applications such as navigation assistance. For example, in the US, the Defense Advanced Research Projects Agency (DARPA) recently held the final round of its AlphaDogfight Trials where an algorithm controlling a simulated F-16 fighter was pitted against an Air Force pilot in virtual aerial combat. The algorithm won by 5-0. So what does this mean for the future of military operations?

The agency’s deputy director remarked that these tools are now ‘ready for weapons systems designers to be in the toolbox’. At first glance, the dogfight shows that an AI-enabled air combat would provide tremendous military advantage including the lack of survival instincts inherent to humans, the ability to consistently operate with high acceleration stress beyond the limitations of the human body and high targeting precision.

The outcome of these trials, however, does not mean that this technology is ready for deployment in the battlefield. In fact, an array of considerations must be taken into account prior to their deployment and use – namely the ability to adapt in real-life combat situations, physical limitations and legal compliance.

Testing environment versus real-life applications

First, as with all technologies, the performance of an algorithm in its testing environment is bound to differ from real-life applications such as in the case of cluster munitions. For instance, Google Health developed an algorithm to help with diabetic retinopathy screening. While the algorithm’s accuracy rate in the lab was over 90 per cent, it did not perform well out of the lab because the algorithm was used to high-quality scans in its training, it rejected more than a fifth of the real-life scans which were deemed as being below the quality threshold required. As a result, the process ended up being as time-consuming and costly – if not more so – than traditional screening.

Similarly, virtual environments akin to the AlphaDogfight Trials do not reflect the extent of risks, hazards and unpredictability of real-life combat. In the dogfight exercise, for example, the algorithm had full situational awareness and was repeatedly trained to the rules, parameters and limitations of its operating environment. But, in a real-life dynamic and battlefield, the list of variables is long and will inevitably fluctuate: visibility may be poor, extreme weather could affect operations and the performance of aircraft and the behaviour and actions of adversaries will be unpredictable.

Every single eventuality would need to be programmed in line with the commander’s intent in an ever-changing situation or it would drastically affect the performance of algorithms including in target identification and firing precision.

Hardware limitations

Another consideration relates to the limitations of the hardware that AI systems depend on. Algorithms depend on hardware to operate equipment such as sensors and computer systems – each of which are constrained by physical limitations. These can be targeted by an adversary, for example, through electronic interference to disrupt the functioning of the computer systems which the algorithms are operating from.

Hardware may also be affected involuntarily. For instance, a ‘pilotless’ aircraft controlled by an algorithm can indeed undergo higher accelerations, and thus, higher g-force than the human body can endure. However, the aircraft in itself is also subject to physical limitations such as acceleration limits beyond which parts of the aircraft, such as its sensors, may be severely damaged which in turn affects the algorithm’s performance and, ultimately, mission success. It is critical that these physical limitations are factored into the equation when deploying these machines especially when they so heavily rely on sensors.

Legal compliance

Another major, and perhaps the greatest, consideration relates to the ability to rely on machines for legal compliance. The DARPA dogfight exclusively focused on the algorithm’s ability to successfully control the aircraft and counter the adversary, however, nothing indicates its ability to ensure that strikes remain within the boundaries of the law.

In an armed conflict, the deployment and use of such systems in the battlefield are not exempt from international humanitarian law (IHL) and most notably its customary principles of distinction, proportionality and precautions in attack. It would need to be able to differentiate between civilians, combatants and military objectives, calculate whether its attacks will be proportionate against the set military objective and live collateral damage estimates and take the necessary precautions to ensure the attacks remain within the boundaries of the law – including the ability to abort if necessary. This would also require the machine to have the ability to stay within the rules of engagement for that particular operation.

It is therefore critical to incorporate IHL considerations from the conception and throughout the development and testing phases of algorithms to ensure the machines are sufficiently reliable for legal compliance purposes.

It is also important that developers address the 'black box' issue whereby the algorithm’s calculations are so complex that it is impossible for humans to understand how it came to its results. It is not only necessary to address the algorithm’s opacity to improve the algorithm’s performance over time, it is also key for accountability and investigation purposes in cases of incidents and suspected violations of applicable laws.

Reliability, testing and experimentation

Algorithms are becoming increasingly powerful and there is no doubt that they will confer tremendous advantages to the military. Over-hype, however, must be avoided at the expense of the machine’s reliability on the technical front as well as for legal compliance purposes.

The testing and experimentation phases are key during which developers will have the ability to fine-tune the algorithms. Developers must, therefore, be held accountable for ensuring the reliability of machines by incorporating considerations pertaining to performance and accuracy, hardware limitations as well as legal compliance. This could help prevent incidents in real life that result from overestimating of the capabilities of AI in military operations.

US Electorate Shows Distrust of the Realities of Foreign Policy

4 September 2020

Bruce Stokes

Associate Fellow, US and the Americas Programme (based in the US)
The identity of the next US president is yet to be determined, but the foreign policy views of the American public are already clear. In principle, Americans support US engagement in the world but, in practice, they worry other countries take advantage of the United States.

Whoever occupies the White House after the election, it is evident the emphasis will be on ‘America First’, and that only characteristics and approaches will differ. If Donald Trump is re-elected, his electoral base will support a continuation of isolationist, protectionist policies. If Joe Biden becomes president, he will enjoy some limited popular backing for international re-engagement, but his voters still clearly want him to prioritize domestic issues.

Implications for the foreign policy of the next US administration are evident. America may have a long history of isolationism, but that should not be confused with ignorance of the growing interconnectedness of today’s world. However, Americans are struggling to find a new equilibrium for their country’s role in the world.

Around seven-in-ten hold the view that the United States should take a leading or major role in international affairs, and the same number acknowledge that international events affect their daily life. But Americans remain reticent about global engagement, and half of registered voters believe other countries take unfair advantage of the United States.

This clear contradiction is mirrored in what can be expected from the election victor, with a Joe Biden administration likely to speak for those who want America to lead, while a second Donald Trump administration is expected to continue complaining about US victimization by an ungrateful world.

A majority (57%) of Americans say foreign policy is 'very important' to them as they decide who to vote for in the 2020 election. This may seem like a high priority, but American polls often show many issues are 'very important' to voters. What matters is relative importance and foreign policy pales in comparison with the significance the public accords to the economy (79%) or healthcare (68%). Immigration (52%) and climate change (42%) are of even less relative importance to voters.

Notably, despite the deep partisanship in American politics today, there is no difference between Republican and Democrat voters on the low priority they accord foreign policy. And barely one-third (35%) of the public give top priority to working with allies and international institutions to confront global challenges such as climate change, poverty and disease — in fact only 31% say improving relations with allies should be a top foreign policy priority over the next five years.

However, despite this apparent lack of support for international relations, a rising majority of Americans believe international trade is good for the economy — running contrary to many international assumptions that Americans are inherently protectionist. But this increased interest may not amount to much in reality. Americans also believe trade destroys jobs and lowers wages. Trump is clearly wedded to a protectionist worldview and may continue to try dismantling the World Trade Organization (WTO). Biden is unlikely to initiate any new trade liberalizing negotiations given what would be, at best, a slim Democratic majority in the Senate and anti-trade views held by many unions and blue-collar voters among his constituency. Any political capital he commits to trade is likely to focus on reforming the WTO, but privately his advisers admit they are not optimistic.

In addition, both Biden and Trump face strong public support for ratcheting up pressure on China, although their lines of attack may differ, with Trump likely to double down on tariffs while Biden would work closely with Europe on both trade and human rights issues. More broadly, almost three-quarters (73%) of Americans now express an unfavourable view of China, up 18 points since the last presidential election. One-quarter of Americans classify Beijing as an ‘enemy’ with almost half saying the US should get tougher with China on economic issues, although attitudes do divide along partisan lines, with Republicans generally more critical of Beijing, but Democrats are tougher on human rights.

On immigration, Trump’s policies are out of step with the public. Six-in-ten Americans oppose expanding the border wall with Mexico, 74% support legal status for immigrants illegally brought to the United States as children — including a majority of Republicans (54%) — and as many Americans favour increasing immigration as support decreasing it. But Trump has already promised to double down on limiting immigration if he wins because it is what his Republican electoral base wants and, as with trade, this is one of his long-expressed personal beliefs. If he wins, expect more mass roundups of undocumented people, completion of his border wall and stricter limitations on legal immigration.

In contrast, Biden is likely to loosen constraints on immigration because he believes immigration has been good for the economy and the Democratic party is increasingly dependent on Hispanic and Asian voters, the two fastest growing portions of the population. However, open borders are not a Biden option. The US foreign-born population is at near-record levels and, every time in American history the portion of foreign born has come close to being 14% of the total population — in the 1880s, the 1920s and now — there has been a populist backlash. Democrats cannot risk that again.

On climate change, there is strong evidence the American public is increasingly worried, and likely to support rejoining the Paris Agreement if Biden is elected and increases US commitments to cut carbon emissions. But the public also appears unlikely to punish Trump if, as promised, he leaves that accord, and he is almost certain to continue denying climate science in the interest of the coal, oil, and gas industries.

The public’s concern about global warming does not necessarily translate into support for taking substantive action. There is a huge partisan divide between the number of Democrats (68%) and Republicans (11%) who say climate change is a very important issue in the 2020 election. When pressed on what action they want on climate change, and who they trust to do it, Americans are less likely than Europeans to accept paying higher prices. A carbon tax stands no chance of passing the Senate, thanks to moderate Democrats from fossil-fuel states, and America’s love affair with large, CO²-emitting vehicles shows no signs of ebbing.

The outcome of the 2020 US election will almost certainly not be determined by foreign concerns, although an international crisis — a terrorist incident, a military confrontation with China or North Korea — could impact voting in an unforeseen way. But given the mood of the American electorate, if Trump is re-elected, there will be scant public pressure for a more activist, collaborative US foreign policy, beyond support for a tough line on China, while a win for Biden will give more room for some international initiatives.

But public opinion data is clear. Voters want the next US president to focus first on domestic issues — overcoming the pandemic, digging the country out of a deep economic hole, calming racial tensions, and reversing inequality. The outcome of the election may end America’s recently antagonistic foreign policy and halt the deterioration of its international role. But dramatic American re-engagement appears unlikely as the public’s priorities lie elsewhere.

Seven Ways the West Can Help Belarus

10 September 2020

Ryhor Astapenia

Robert Bosch Stiftung Academy Fellow, Russia and Eurasia Programme
Outlining the key steps that government, international institutions, and NGOs can take to bring an end to the suffering of the Belarus people.

2020-09-10-Belarus-Protest-Lukashenka

1. Acknowledge the new reality

A huge number of Belarusians across all levels of society simply no longer recognize Lukashenka as their legitimate president. The unprecedented size and persistence of protests against his regime and the sheer scale of reports of repressive actions, torture, and even murder, mean Belarus will never be the same again.

However, current paralysis in EU policy and the absence of a comprehensive US policy are both serving as a de facto licence for Lukashenka to deepen the political crisis. The sooner policymakers realize this and act with more responsibility and confidence, the quicker the increasing repression can be reversed.

2. Do not recognize Lukashenka as president

If the international community stops recognizing Lukashenka as president, it makes him more toxic to others, including Russia and China, both of which will be reluctant to waste resources on someone who is seen as the main cause of Belarusian instability. Even if Russia still decides to save Lukashenka and financially support him, ignoring Lukashenka decreases the legitimacy of any agreements he signs with the Kremlin on collaboration or integration.

Demanding a re-run of the presidential election should also remain firmly on the agenda as functionaries within Lukashenka's system should know this international pressure is not going away until a truly transparent vote takes place.

3. Be present on the ground

In order to curb repression and establish ties with actors within Belarus, a monitoring group should be organized under the auspices of the UN, the OSCE or other international organizations to establish a presence on the ground, and to stay in the country as long as it is needed, and is possible. Governments and parliaments can send their own missions, while staff from international media and NGOs should be encouraged to report on what is actually happening inside the country.

The bigger the visible presence of the international community is in Belarus, the less brutal Lukashenka’s agencies can be in persecuting protestors, which in turn would then allow more substantial negotiations to take place between the democratic movement and Lukashenka.

4. Announce a package of economic support for a democratic Belarus

The Belarusian economy was already in bad shape before the election, but the situation is going to get much worse. The only way out is support from the international community with a ‘Marshall Plan for a democratic Belarus’. States and international financial institutions should declare they will provide significant financial assistance through grants or low-interest loans, but only if there is democratic change first.

It is essential to make this economic package conditional on democratic reform, but also that it will have no geopolitical strings attached. If a democratically-elected government decides it wants to improve relations with Russia, it should still be able to count on an assistance package.

This would send a strong signal to economic reformers who remain inside Lukashenka's system, giving them a genuine choice between a functioning Belarusian economy or sticking with Lukashenka, whose leadership is seen by many as to be responsible for ruining the country’s economy.

5. Introduce targeted political and economic sanctions

The Lukashenka regime deserves tough sanctions internationally, but so far only selective visa restrictions or account freezes have been imposed, which have little to no effect on what is actually happening on the ground. Visa sanction lists need to be expanded but, more importantly, there should be increased economic pressure on the regime. Companies which are the most important to Lukashenka's business interests should be identified and targeted with sanctions, all their trading activity halted, and all their accounts abroad frozen.

Governments should also persuade their own country’s large companies to reconsider working with Belarusian producers. It is shameful that international corporations continue to advertise in media controlled by Lukashenka and appear to be ignoring the reports of human rights violations at Belarusian companies they do business with.

Moreover, there should be a deadline set to halt all repression, or broader economic sanctions will be imposed. This would send a strong message to Lukashenka and also his entourage, many of whom would then become more convinced he has to go.

6. Support NGOs to investigate allegations of torture

There are few legal mechanisms to prosecute those thought to be involved in election fraud and acts of brutality. Nevertheless, all reports of torture and falsifications should be properly documented by human rights defenders, including identifying those alleged to have taken part. Gathering evidence now prepares the ground for investigations, targeted sanctions, and leverage on law enforcement officials in the future.

But, given that such an investigation is not possible in Belarus right now, international human rights activists should be enabled to start the process outside the country with support from Belarusian NGOs.

7. Support known victims of the regime

Even with an unprecedented campaign of solidarity among Belarusians, many people need support, especially those alleged to have suffered torture. Some media outlets claim to have lost a significant amount of revenue because advertisers were forced to pull out, and journalists arrested. Human rights defenders need funds to keep organizations running in the heat of this crackdown.

Supporting all these people and organizations will cost tens of millions of euros, but it would significantly ease the huge financial burden facing those who have opposed the regime.

Novichok Poisons Germany's Relations with Russia

14 September 2020

John Lough

Associate Fellow, Russia and Eurasia Programme
The conclusion of a specialist German military laboratory that Alexey Navalny was poisoned with the nerve agent novichok has shocked Germany’s political class and is forcing the government to re-assess relations with Russia.

When Chancellor Angela Merkel offered to provide medical care for Navalny in Germany after he fell ill from suspected poisoning in Russia, she could have hardly expected her humanitarian gesture would trigger a crisis in her country’s relations with Russia.

Merkel has used uncharacteristically blunt words to condemn the apparent attempt on Navalny’s life, saying the use of novichok raises serious questions that only the Russian government could answer. She described Navalny as being the ‘victim of a crime’ which was a violation of the ‘basic values and basic rights’ that Germany and its allies were committed to. Her tone and body language certainly showed how strongly she felt about the issue.

Germany’s Social Democrat foreign minister Heiko Maas then followed up by suggesting Russia’s response might force Germany to change its position on the construction of the Nord Stream 2 pipeline which aims to double Germany’s direct gas imports from Russia under the Baltic Sea.

This is a dramatic change of position since his party has been a staunch supporter of the controversial project. Two Christian Democrat candidates for the Chancellorship called for a stop to the pipeline together with representatives from the Greens, who could be part of a government coalition after the 2021 federal election.

Claims of hostile provocation

The Russian foreign ministry shot back with a statement condemning Berlin’s ‘unsubstantiated accusations and ultimatums’ and claiming Germany was using Navalny’s hospitalisation to discredit Russia internationally. It demanded Germany share data and test results with the Russian Prosecutor’s Office, saying any failure to comply would be ‘a crude hostile provocation against Russia’ that risked consequences for the bilateral relationship as well as ‘serious complications in the international situation’.

Such strong language from Moscow towards Germany has not been seen for over 30 years, and is all the more remarkable as Putin has personally invested heavily in the relationship with Germany in view of its economic and political importance, and its strong desire for constructive ties with Russia. Until 2014, Russian analysts viewed Germany as Russia’s ‘lobbyist’ in Europe.

Berlin is now trying to downplay the situation, claiming the Navalny poisoning is not actually a Germany-Russia matter and referring it to the Organisation for the Prohibition of Chemical Weapons. By consulting with its EU and NATO allies, Berlin is further internationalising the issue to reduce impact on the bilateral relationship.

Such a forceful reaction to the poisoning reflects Germany’s increasing frustration with the Kremlin. The murder in broad daylight in Berlin in August 2019 of a Chechen wanted by the Russian authorities has been traced to the FSB. And the publication of a report in May 2020 into the hacking of the German parliament in 2015, including Merkel’s parliamentary office, was a further reminder of how far Russia had deviated from the course of partnership that Berlin believed the two countries had established in the 1990s.

Merkel described the cyberattack as ‘monstrous’, saying it was part of a strategy of hybrid warfare that includes ‘disorientation’ and ‘manipulation of facts’. Further tension has been added since the recent Belarus election as Moscow is supporting Lukashenka’s presidency whereas the EU does not recognise him as the legitimate president.

This accumulation of events is forcing German policymakers to recognise the Russian leadership is a menace to its own citizens, its neighbours and to Germany itself. Although Berlin abandoned several of its illusions about partnership with Russia in 2014 when it led the EU response to Russia’s annexation of Ukraine and destabilization of south-eastern Ukraine, it still hoped that the Kremlin would see reason and adjust its policies.

It combined sectoral economic sanctions with continuing dialogue and a joint effort to help settle the conflict in Donbas despite the obvious fact that Russia was a party to the conflict. It still believed that Moscow had an interest in finding a compromise. Instead, experience so far suggests Russia has a greater interest in keeping the conflict ‘semi-frozen’ as a way of forcing Ukraine to compromise.

Controversially, Germany also saw the need to expand energy relations with Russia in a bid to stabilise ties and draw Russia closer to Europe. The Nord Stream 2 pipeline initiated in September 2015 by Gazprom and five European companies – two of them German – is a monument to this policy.

Even though this project lacked an overall economic rationale, the German government supported it – much to the consternation of the Baltic States, Poland and others who objected to what they saw as Berlin’s insistence on a ‘Russia-first’ policy that undercut the interests of Ukraine. This was because the pipeline’s purpose is to re-route gas flows away from Ukraine, depriving it of transit revenues and a lever of influence in its relations with Moscow.

It now appears the German government is finally waking up to the fact that its attempts to encourage better Russian behaviour have failed. Policy looks set to become tougher and a moratorium on Nord Stream 2 now appears a real possibility if Russia fails to investigate the Navalny poisoning and provide adequate answers.

However, sanctioning the new pipeline is likely to provoke counter-measures against German business interests in Russia. If Berlin is determined to pursue this tougher line, it could end up facing an uncomfortable dilemma and being forced to consider alternative ways to signal displeasure at Russia’s criminal actions.

Inhibition of mitochondrial oxidative metabolism attenuates EMCV replication and protects {beta}-cells from virally mediated lysis [Immunology]

Viral infection is one environmental factor that may contribute to the initiation of pancreatic β-cell destruction during the development of autoimmune diabetes. Picornaviruses, such as encephalomyocarditis virus (EMCV), induce a pro-inflammatory response in islets leading to local production of cytokines, such as IL-1, by resident islet leukocytes. Furthermore, IL-1 is known to stimulate β-cell expression of iNOS and production of the free radical nitric oxide. The purpose of this study was to determine whether nitric oxide contributes to the β-cell response to viral infection. We show that nitric oxide protects β-cells against virally mediated lysis by limiting EMCV replication. This protection requires low micromolar, or iNOS-derived, levels of nitric oxide. At these concentrations nitric oxide inhibits the Krebs enzyme aconitase and complex IV of the electron transport chain. Like nitric oxide, pharmacological inhibition of mitochondrial oxidative metabolism attenuates EMCV-mediated β-cell lysis by inhibiting viral replication. These findings provide novel evidence that cytokine signaling in β-cells functions to limit viral replication and subsequent β-cell lysis by attenuating mitochondrial oxidative metabolism in a nitric oxide–dependent manner.

The bacterial cell division protein fragment EFtsN binds to and activates the major peptidoglycan synthase PBP1b [Metabolism]

Peptidoglycan (PG) is an essential constituent of the bacterial cell wall. During cell division, the machinery responsible for PG synthesis localizes mid-cell, at the septum, under the control of a multiprotein complex called the divisome. In Escherichia coli, septal PG synthesis and cell constriction rely on the accumulation of FtsN at the division site. Interestingly, a short sequence of FtsN (Leu75–Gln93, known as EFtsN) was shown to be essential and sufficient for its functioning in vivo, but what exactly this sequence is doing remained unknown. Here, we show that EFtsN binds specifically to the major PG synthase PBP1b and is sufficient to stimulate its biosynthetic glycosyltransferase (GTase) activity. We also report the crystal structure of PBP1b in complex with EFtsN, which demonstrates that EFtsN binds at the junction between the GTase and UB2H domains of PBP1b. Interestingly, mutations to two residues (R141A/R397A) within the EFtsN-binding pocket reduced the activation of PBP1b by FtsN but not by the lipoprotein LpoB. This mutant was unable to rescue the ΔponB-ponAts strain, which lacks PBP1b and has a thermosensitive PBP1a, at nonpermissive temperature and induced a mild cell-chaining phenotype and cell lysis. Altogether, the results show that EFtsN interacts with PBP1b and that this interaction plays a role in the activation of its GTase activity by FtsN, which may contribute to the overall septal PG synthesis and regulation during cell division.

Inhibition of oxidative metabolism by nitric oxide restricts EMCV replication selectively in pancreatic beta-cells [Enzymology]

Environmental factors, such as viral infection, are proposed to play a role in the initiation of autoimmune diabetes. In response to encephalomyocarditis virus (EMCV) infection, resident islet macrophages release the pro-inflammatory cytokine IL-1β, to levels that are sufficient to stimulate inducible nitric oxide synthase (iNOS) expression and production of micromolar levels of the free radical nitric oxide in neighboring β-cells. We have recently shown that nitric oxide inhibits EMCV replication and EMCV-mediated β-cell lysis and that this protection is associated with an inhibition of mitochondrial oxidative metabolism. Here we show that the protective actions of nitric oxide against EMCV infection are selective for β-cells and associated with the metabolic coupling of glycolysis and mitochondrial oxidation that is necessary for insulin secretion. Inhibitors of mitochondrial respiration attenuate EMCV replication in β-cells, and this inhibition is associated with a decrease in ATP levels. In mouse embryonic fibroblasts (MEFs), inhibition of mitochondrial metabolism does not modify EMCV replication or decrease ATP levels. Like most cell types, MEFs have the capacity to uncouple the glycolytic utilization of glucose from mitochondrial respiration, allowing for the maintenance of ATP levels under conditions of impaired mitochondrial respiration. It is only when MEFs are forced to use mitochondrial oxidative metabolism for ATP generation that mitochondrial inhibitors attenuate viral replication. In a β-cell selective manner, these findings indicate that nitric oxide targets the same metabolic pathways necessary for glucose stimulated insulin secretion for protection from viral lysis.

Power for refugees: Electricity

Power for refugees: Electricity Audio bhorton.drupal 16 May 2022

A new podcast special explores an often-overlooked aspect of humanitarian assistance: access to energy.

From Afghanistan to Ukraine to Sudan - the world is grappling with the consequences that emerge when people are forced to flee from their homes. One factor that does not usually make the headlines is that many people displaced by conflict or natural disasters lack access to the energy services that are necessary for forging dignified lives and livelihoods. 

This first episode of a two-part Undercurrents special examines efforts to electrify refugee settlements in Ethiopia, Kenya and Rwanda, shedding light on what has worked and what has not. Approximately 94% of forcibly displaced people living in these settlements do not have access to electricity to heat or cool hospitals, schools and dwellings, or to light streets.

Since 2015, Chatham House has been researching this issue and convening dialogues to spur action by humanitarians, energy companies and others. Our seminal Heat, Light and Power report provided the first ever comprehensive assessment of access to energy in refugee camps and urban areas with high numbers of refugees.

This two-part podcast is part of the Renewable Energy for Refugees project. Led by Practical Action, the project provides access to affordable and sustainable sources of renewable energy, and improves the health, wellbeing and security of refugees and neighbouring communities.

COP27: Navigating a difficult road to Sharm El-Sheikh

COP27: Navigating a difficult road to Sharm El-Sheikh Expert comment NCapeling 6 July 2022

Against a backdrop of rising urgency, COP27 in Egypt will bring all aspects of climate action into the spotlight – but especially the role of the host country.

As COP26 drew to a close in Glasgow, Egyptian officials announced their priorities for COP27, emphasizing climate finance and climate adaptation – a new approach given previous COPs mainly focused on mitigation, reducing emissions to limit climate damage.

This was followed by the COP27 presidency outlining its vision at MENA Climate Week 2022 to achieve ‘substantive and equal progress’ on all aspects of the negotiations, and Egypt emphasizing its intention to focus on implementing existing carbon reduction targets rather than pushing for further carbon cuts.

Egypt argues it is hosting COP27 on behalf of African nations and that, while it is promoting the interests of the developing world, it will be an impartial arbiter. However it is also useful to consider its priorities from the Egyptian government’s perspective.

Agenda drivers

Egypt has long prioritized climate finance and adaptation because it remains in need of technical and financial support to adapt, especially in agriculture and tourism.

It plans to expand its access to climate funding and investment, an area in which Egypt has been relatively successful as it currently receives 27 per cent of all multilateral climate finance in the MENA region and has issued the region’s first sovereign green bonds.

With public debt currently 94 per cent of GDP, Egyptian officials have also called for debt relief for Egypt and other developing countries.

Egypt’s Climate Change Strategy reflects this approach, aiming to enhance Egypt’s rank on the Climate Change Performance Index in order to ‘attract more investments and acquire more climate funding’.

Not pushing for more emission reductions at this critical moment risks derailing global decarbonization momentum and undermining global climate action

Limiting the mitigation scope and the focus on finance also echoes Egypt’s own reluctance to make carbon reduction commitments. The Egyptian nationally determined contribution (NDC) – its 2030 pledge under the Paris Agreement – does not include any quantifiable emission reduction targets.

Egypt is one of only a few countries which failed to submit an updated NDC in 2021 and its upcoming update will not include an economy-wide carbon reduction target.

Egypt has also never published a long-term strategy and has no decarbonization plans despite independent estimates it should cut rising emissions by one-quarter by 2030, and by two-thirds by 2050 to be aligned with the Paris Agreement. This partly explains why observers rate Egypt’s climate action as highly insufficient.

Furthermore, Egypt’s championing of ‘moving from pledges to implementation’ without having quantifiable carbon reduction pledges of its own effectively exempts it from both pledging and implementation.

As a developing country, Egypt’s negotiating position is supported by UNFCCC provisions which recognize differentiated responsibilities and respective capabilities of nations.

Its proposal to focus COP27 on the implementation of climate action and finance pledges is important in consolidating progress. But not pushing for more emission reductions at this critical moment risks derailing global decarbonization momentum and undermining global climate action.

According to optimistic estimates, if current climate pledges were implemented the world would still remain on track for 2°C of warming by the end of the century, with far worse impacts than if warming was curbed at 1.5°C.

Under a 2°C scenario, 37 per cent of the global population could regularly be exposed to extreme heat waves compared to 14 per cent in a 1.5°C warmer world, with developing countries expected to be worst-affected.

A 2°C trajectory also runs the risk of tipping points such as the melting of ice sheets in Antarctica and Greenland, triggering runaway climate change. Time to change the warming trajectory is running out as the latest IPCC assessment warns the window of opportunity is now ‘brief and rapidly closing’, and the UN Secretary General recently called for faster carbon cuts by the end of 2022 to avoid a ‘climate catastrophe’.

A different energy transition

Egypt opted not to join any of the voluntary sectoral coalitions at COP26 on reducing methane, clean energy transition, transition to zero-emissions vehicles, or moving beyond oil and gas.

This position is explained by its growing role as an exporter and advocate for fossil gas in the energy transition. Egypt is the second-largest producer of natural gas in Africa and is emerging as a fossil gas hub for the eastern Mediterranean, which is shaping its domestic energy policy.

Egypt is open to dialogue – not just on refining the COP27 agenda but also on reviewing its own climate priorities and leveraging its energy sector for a more ambitious transition

Its 59GW electricity generation capacity is almost double the peak demand and is dominated by gas-powered electricity generation, which currently represents 42 per cent of all Africa’s gas generation.

Egypt’s climate policy is also shaped by fossil gas, and its national Climate Change Strategy encourages the expansion of gas use by promoting a transition to compressed natural gas for vehicles, the expansion of its domestic natural gas network – despite having universal access to electricity – and shifting to a gas-fuelled shipping sector.

Egypt also voiced support for other African countries to extract and deploy fossil gas and oil resources, making it one of the protagonists of the ‘great fossil gas pushback’. These advocates defend the right of developing countries to deploy fossil gas as a ‘transition fuel’ and champion its necessity to solve energy poverty.

But their position is not shared by all African and developing countries, and is rejected by some civil society groups, who argue it risks locking in greenhouse gases and local emissions for decades as well as delaying future development of low carbon energy systems.

Egypt’s huge spare generation capacity has contributed to a slowdown in renewable energy projects over the past two years. With renewables representing just 6GW, Egypt is expected to miss its renewable energy target for 2022, set at 20 per cent of generating capacity.

Engaging Egypt better

But these positions are more malleable than they seem, and Egypt is open to dialogue – not just on refining the COP27 agenda but also on reviewing its own climate priorities and leveraging its energy sector for a more ambitious transition.

Youth innovation can help shape the future of African cities

Youth innovation can help shape the future of African cities Expert comment LToremark 16 August 2022

To meet the challenges of rapid urbanization, African governments must harness the potential of young innovators to help shape the future of African cities.

It is projected that 1.3 billion people will be living in Africa’s cities by 2050, an increase of almost 1 billion from today, and largely driven by young people migrating to urban centres in search of work. As the continent’s urban population grows, cities will need to adapt by nurturing new economic ecosystems to create jobs, while managing the environmental, social and political pressures that urbanization brings.

The evolution of Africa’s cities is critical for meeting the demands of its youth population and must be co-created with them. Africa’s young innovators are already proving to be an asset in shaping the future of African cities and, if they are allowed to flourish, they could be at the forefront of finding much-needed solutions to the continent’s vast urban challenges.

Growing tech hubs

African countries are increasingly benefitting from growth in technology ecosystems, which are often clustered within cities. There are currently more than 600 tech hubs helping to incubate innovative solutions across cities in Africa. Between 2015 and 2020, the number of start-ups receiving funding grew six times faster than the global average. In 2021 alone, start-ups raised over $4billion in funding – twice as much as in 2020.

But significant challenges remain. While the number of new start-ups is an encouraging indication of the entrepreneurialism and creativity of Africa’s youth, job creation on the level required will demand that they grow and scale up to generate more and higher quality jobs. Research on scaling up in Africa is sparse but research by Endeavor suggests that in Nairobi – one of Africa’s top tech ecosystems – only 5 per cent of companies are able to sustain growth of 20 per cent or more each year, yet they created 72 per cent of new jobs in the previous three years. For Africa to fully harness the potential of digital innovation, making cities the best place for young people to launch ideas and grow them into thriving businesses must become a priority policy for African governments. 

Barriers to scale

On the most basic level, business growth needs access to the services that make cities more liveable and help both urban residents and firms become more productive, such as healthcare, transport, water and sanitation. African cities already struggle to provide their residents – in particular the poorest and most vulnerable – with equitable, reliable, affordable and quality access to these services, in a sustainable manner. And these challenges will only get more acute as urban populations rise rapidly, often without any kind of integrated planning.

For example, an estimated 70-80 per cent of municipal solid waste in Africa is recyclable, yet only about 4 per cent is currently recycled, with more than 90 per cent of waste ending up in uncontrolled dumpsites and landfills. As Africa’s urban population grows, these conditions are likely to worsen – unless there is urgent action. New technology has the potential to help by creating a positive feedback loop between innovation, service delivery and growth. For example, to bridge the waste management gap, innovators are exploring various tech-enabled circular economy models. These solutions are often ground-breaking and have the potential to leapfrog traditional waste management infrastructure. Crucially, they are also formalizing a largely informal sector and creating new jobs.

Across the continent, start-ups like Kaltani, Mr Green Africa and Freetown Waste Transformers build processing facilities to turn waste into energy or reusable products, such as construction materials. Others, like Scrapays, Regenize and Soso Care, are helping households and businesses sell off their recycled materials for cash and virtual currencies or exchange them for critical services, such as micro health insurance premiums. Such start-ups help empower informal waste pickers or agents with tech-enabled tools and target low-income urban communities that would not normally prioritize recycling.

Help or hindrance from the top?

But Africa’s young people cannot do this alone – government decision-makers must become catalysts for entrepreneurial leadership. This requires nurturing a mindset that sees young innovators as Africa’s biggest resource, not a threat. While the importance of young people to Africa’s development is acknowledged in various high-level regional treaties, patterns of inhibition and outright hostility from political ‘elites’ suggest that the disruptive nature of technology start-ups and their access to significant capital through venture capital funding models – unlike existing rent-seeking business models with government control – threatens the political establishment.

Africa’s young people cannot do this alone – government decision-makers must become catalysts for entrepreneurial leadership.

The growing use of tech solutions also leads to increased transparency and efficiency of service delivery, which in turn leads to increased demand for government accountability and pressure to adopt more liberal policies. Until there is a shift towards catalysing entrepreneurial leadership, there is a stronger incentive for political elites to leverage their powers to co-opt successful technology businesses, or otherwise try to control them for political gain, than let them flourish. This shift in mindset will be critical to unlocking the full potential of Africa’s young innovators.

A new vision for African agency in sustainable development

A new vision for African agency in sustainable development Expert comment LJefferson 18 October 2022

Change is necessary not only in global economic structures and attitudes – but in African governance too.

The conventional notion that Africa is mostly a consumer of norms and practices designed by the Global North has been repeatedly challenged and is increasingly being debunked. Increased African agency in international affairs is today a well-established and documented reality. But Africa’s influence still does not match the scale of the challenges that it faces on its pathway to sustainable development. 

Pushing for African agency in sustainable development also warrants a critical assessment of how ‘sustainable development’ should be defined, and how it can be achieved in terms of actual poverty reduction and real improvement in the lives of local poor Africans. Sustainable development has been a political catchphrase for over 30 years – but a genuine transition towards sustainability has yet to begin.

African agency today

Historically, there have been structural limitations on the agency of African stakeholders to shape development pathways. Chief among them, donor-recipient power dynamics have persistently promoted dependency and sustained institutional corruption. Many African countries are also challenged by economic incentives and infrastructure that have favoured the market demands and supply chains of former colonial powers, which largely remain reliant on natural resource extraction, and are marked by limited investment in value-addition activities and technology development.

Donor-recipient power dynamics have persistently promoted dependency and sustained institutional corruption.

Today, however, African agency is being exerted in a more assertive fashion. The African Union (AU), individual African states, civil society, the private sector and eminent and ordinary persons are all displaying Africa’s agency in steering global sustainable development priorities, namely by proposing their own development agenda, The African Union Agenda 2063, adopted in 2013. This was followed by the UN Sustainable Development Goals (Agenda 2030), which in many ways mirror Agenda 2063 – a clear demonstration of the influence of Africa in the global arena. 

Agenda 2063 is a strategic roadmap for Africa ‘to build an integrated, prosperous and peaceful Africa, driven and managed by its own citizens and development goals representing a dynamic force in the international arena’. Prepared following a broad-based participatory consultation, it advocates for inclusion and empowerment and provides an excellent vision for African countries and African people. The SDGs address several of the key shortcomings of their predecessor – the MDGs – and incorporate a broader and more transformative agenda that more adequately reflects the complex challenges of the 21st century and the need for structural reforms in the global economy and governance norms.

In international forums on sustainable development, African countries are increasingly using their collective voice to change the discourse on how development can and should be done. For instance, by championing innovative solutions for carbon markets, African policy leaders are enabling access to climate finance for development while preserving Africa’s natural wealth.

In the post-COVID era, championing investments in and leadership of Africa’s global health architecture demonstrates a desire that in the next pandemic, Africa CDC, AMA and continental manufacturers will play leading roles in determining Africa’s public health strategy and implementation.

In trade, building on the groundwork led by the regional economic commissions, the AfCFTA will catalyse and scale regional integration, trade and cooperation, leading to promising new modes of supply chain and self-sufficiency.

Encouraging signs, but persistent shortcomings

Encouraging signs that African agency is gaining momentum cannot disguise the fact that Africa has yet to move from rhetoric to implementation in the realm of sustainable development. Continental visions often fail to go beyond declarations of intent, and have only limited influence on governance systems or national structural transformation, and African states remain vulnerable to economic shocks emanating from the global system.

African agency should not be only seen as emanating from government, but also as being exerted by independent civil society organizations and committed ordinary individuals.

Change will require governance systems that are coordinated, transparent, efficient, and inclusive, as well as tools, processes, and means (material, technical, and human) for successful implementation. There is an urgent need for a new governance paradigm in Africa and internationally, dealing with long-term social change.

Notably, African agency should not be only seen as emanating from government, but also as being exerted by independent civil society organizations and committed ordinary individuals. Effective agency needs to be multi-faceted and multi-actor, and depends on the inclusiveness of African governments and their willingness to work with civil society in their strategic engagements with external partners.

Both Agenda 2063 and the SDGs hold the potential for transformation, but implementation will depend on continued advocacy to hold authorities to account and change the dominant discourse, logic and rules of engagement at global, regional, national, and local levels. There is a need for a dynamic new model of African ‘development’.

Time for a new vision

Africa’s economic landscape is changing rapidly, with new regional and local value chains, and integrated regional economic corridors to link countries, minimize the burden of high-cost production and logistics, and boost real incomes and international competitiveness. But Africa continues to face structural challenges, including the need for large investment projects – at a time when Africa remains a net exporter of capital.

Donors and development partners must reflect upon their prior modes of engagement and commit to genuine and equitable relationships with African states. Such partnerships must reflect mutual respect of ideas and accountability, and commit to making space in international forums and multi-lateral arrangements for African people and countries to realize their own visions for progress.

More resources should be channelled to actors engaging closest to communities and people, who can better understand and communicate local needs.

But African leaders and actors must also recognize that with the advent of resources and agency comes responsibility for results and outcomes, notably the need to improve governance. Gaps in accountability, widespread corruption, and lack of successful implementation and sustainability of projects must be addressed.

Africa-Japan relations and evolving multilateralism

Africa-Japan relations and evolving multilateralism 23 November 2022 — 9:00AM TO 10:30AM Anonymous (not verified) 17 November 2022 Online

This panel discussion reflects on the outcomes of TICAD 8 in 2022 and looks forward to TICAD 9 in 2025.

The eighth edition of the Tokyo International Conference on African Development (TICAD), held in Tunisia from 27–28 August 2022, marked the second time that Japan’s now-triennial summit was hosted in an African country, after TICAD 6 was held in Kenya in 2016.

The summit was attended by 48 representatives of African countries and at least 20 heads of state and government and included a pledge by the Japanese government to commit $30 billion in public and private finance to Africa over the next three years.

In reaffirming the three pillars of TICAD 8 – revolving around the economy, societal resilience, and peace and stability – the newly adopted Tunis Declaration (28 August 2022) also outlined some of the key projects underpinning Japan’s pledge, including a $4 billion fund for a Green Growth Initiative with Africa (GGA).

2023 will mark 30 years since the inception of TICAD in 1993 and ten years since the African Union (AU)’s adoption of its flagship Agenda 2063, on which the Tunis Declaration placed distinct emphasis.

This panel discussion reflects on the outcomes of TICAD 8 in 2022 and looks forward to TICAD 9 in 2025, exploring wider developments in summitry, Africa-Asia relations, and modes of multilateralism.

Questions explored include:

  • How has international summitry evolved over the past three decades since the inception of TICAD in 1993, which represented the first periodic high-level summit engagement with Africa by a ‘non-traditional’ partner?
  • Looking ahead to TICAD 9 in 2025, what are the priorities for enforcing the stated tenets of TICAD – ‘African ownership, international partnership, inclusivity and openness’ – in cooperation efforts?
  • What lessons can be drawn from TICAD’s co-partnership approach (with the African Union Commission and others) – particularly given increasing calls for AU membership of the G20 and Prime Minister Kishida’s pledge at TICAD 8 to support a permanent African UNSC seat during its non-permanent membership in 2023–24? Beyond membership, what are the priorities for furthering agency?
  • How are Africa-Asia relations evolving and diverging? How are Japan and other Asian countries perceived by different African countries?

This event is the third in the Chatham House – Japan House London webinar series (2022-2023). The series is held in partnership with Japan House London. You can watch previous webinars from the series here.

China-Africa relations

China-Africa relations Explainer jon.wallace 18 January 2023

What are China’s objectives in Africa, how valid is the concept of ‘debt trap’ diplomacy, and what are China’s military ambitions in the region?

A brief history of China-Africa relations

Africa has been crucial to China’s foreign policy since the end of the Chinese civil war in 1947. China supported several African liberation movements during the Cold War, and for every year since 1950 bar one, the foreign minister of the People’s Republic of China (PRC) has first visited an African country.

China’s new foreign minister Qin Gang visited five African countries and the African Union in January 2023. Wang Yi, the former foreign minister, visited 48 African countries and premier Xi Jinping undertook 10 visits to Africa between 2014 and 2020.

China-Africa relations are the bedrock of China’s foreign policy.
 

Chinese foreign minister Qin Gang, speaking in December 2022

In 1971, the votes of African countries were instrumental in winning the PRC control of China’s seat in the UN General Assembly and Security Council – displacing representatives from Chinese nationalist forces, who had been defeated in the civil war and now governed Taiwan.

In the following decades, China’s focus in Africa switched to eliminating all remaining recognition for Taiwan’s government. Burkina Faso, Malawi, Liberia, Senegal and others all switched their recognition from Taiwan to the PRC. Eswatini is the only African nation still to recognize Taiwan’s government in 2023.

In 1999 China created its ‘Going Out’ strategy, which encouraged Chinese companies to invest beyond China.

The strategy was a statement of China’s growing economic might and created a new wave of Chinese engagement in Africa. It was also an important source of employment for Chinese citizens working on new infrastructure projects.

In November 2003 the first tri-annual Forum for China-Africa Cooperation (FOCAC) summit was held in Beijing. FOCAC was created to improve cooperation between China and African states and signalled China’s growing strategic initiative in Africa.

In 2013, China’s Belt and Road Initiative (BRI) was launched by Xi Jinping, featuring an ambition to reinvigorate the old silk trading route along the East African coast. This should theoretically have seen Chinese investment concentrated in East Africa, but many other African states also sought opportunities through the BRI, making the initiative quickly expand in scope and ambition.

The BRI saw a huge number of signature infrastructure projects built across Asia and Africa, funded by Chinese loans whose size, nature and origin were often opaque. Some African countries became badly exposed to Chinese lending during this period. 

Chinese investment peaked around 2016. Since then, Chinese loans to African governments declined significantly, falling from $28.4 billion in 2016 to $1.9 billion in 2020 – partly due to changing priorities in domestic Chinese politics, and partly due to the apparent difficulty African countries had repaying loans.

China’s investment in Africa

China has taken a position contrary to Western governments in its African investment. It characterizes its loans as mutually beneficial cooperation between developing countries, promising not to interfere in the internal politics of those it loans to.

In this respect it presents itself in contrast to Western countries, who are accused by China and some African governments of arrogant, democratic posturing – often by former colonial powers that looted African resources during the 18th and 19th centuries.

China has learned by doing, and the reality of large-scale investments taught Chinese investors the limits of their approach. For instance, during the South Sudanese civil war, China had to deal with representatives of various forces opposed to the government to maintain the Greater Nile Oil Pipeline, operated by the China National Petroleum Corporation.

China has not made significant efforts to export communist ideology in Africa since the Cold War ended.

China has not made significant efforts to export communist ideology in Africa since the Cold War ended, claiming that Chinese communism could not be replicated outside of China.

However, ideological links exist between the Chinese Communist Party (CCP) and the rulers of a state like Ethiopia, whose Prosperity Party has origins in ‘revolutionary democracy’ and Marxist-Leninism.

China’s National People’s Congress has formal relations with 35 African parliaments and the CCP International Liaison Department (ILD) has relations with 110 political parties in 51 African countries.

Western politicians have increasingly voiced fears that China’s intentions in Africa are predatory, intended to create a network of African states that are obliged to service their debts by offering China access to resources, trade opportunities and locations for military bases.

Debt trap diplomacy

US commentators often describe Chinese policy in Africa as a ‘debt trap’, part of a deliberate strategy to loan unmanageable sums to African countries, draw them into China’s sphere of influence, and force unfair commitments upon them.

Some African nations do have extensive Chinese loans and are suffering from out-of-control debt, exacerbated by the COVID-19 pandemic, the invasion of Ukraine, and high interest rates. But their situations cannot be entirely blamed on Chinese loans. States including Kenya and Zambia have poorly managed their debt to all creditors, not only China.

Meanwhile, other African countries have created realistic, manageable debt arrangements with China without the tremendous risk and uncertainties that characterized some major BRI projects.

China also faces significant problems due to its extensive loans made during the BRI boom period, as it will struggle to force repayment while maintaining its image as a friend of developing nations.

BRI projects were largely uncoordinated and unplanned, with credit offered by competing Chinese lenders. This contradicts the idea of a coherent ‘debt trap’ policy by China.

However, the idea that China may use debt strategically, to expand its influence in the African content and secure access to resources, cannot be completely dismissed. China is an emerging superpower in strategic competition with the US. Building stronger economic relationships in Africa would be a logical step in its aspirations to be a global power.

SNMMI Procedure Standard/EANM Practice Guideline for Brain [18F]FDG PET Imaging, Version 2.0

PREAMBLE

The Society of Nuclear Medicine and Molecular Imaging (SNMMI) is an international scientific and professional organization founded in 1954 to promote the science, technology, and practical application of nuclear medicine. The European Association of Nuclear Medicine (EANM) is a professional nonprofit medical association that facilitates communication worldwide between individuals pursuing clinical and research excellence in nuclear medicine. The EANM was founded in 1985. The EANM was founded in 1985. SNMMI and EANM members are physicians, technologists, and scientists specializing in the research and practice of nuclear medicine.

The SNMMI and EANM will periodically define new guidelines for nuclear medicine practice to help advance the science of nuclear medicine and to improve the quality of service to patients throughout the world. Existing practice guidelines will be reviewed for revision or renewal, as appropriate, on their fifth anniversary or sooner, if indicated.

Each practice guideline, representing a policy statement by the SNMMI/EANM, has undergone a thorough consensus process in which it has been subjected to extensive review. The SNMMI and EANM recognize that the safe and effective use of diagnostic nuclear medicine imaging requires specific training, skills, and techniques, as described in each document. Reproduction or modification of the published practice guideline by those entities not providing these services is not authorized.

These guidelines are an educational tool designed to assist practitioners in providing appropriate care for patients. They are not inflexible rules or requirements of practice and are not intended, nor should they be used, to establish a legal standard of care. For these reasons and those set forth below, both the SNMMI and the EANM caution against the use of these guidelines in litigation in which the clinical decisions of a practitioner are called into question.

The ultimate judgment regarding the propriety of any specific procedure or course of action must be made by the physician or medical physicist in light of all the circumstances presented. Thus, there is no implication that an approach differing from the guidelines, standing alone, is below the standard of care. To the contrary, a conscientious practitioner may responsibly adopt a course of action different from that set forth in the guidelines when, in the reasonable judgment of the practitioner, such course of action is indicated by the condition of the patient, limitations of available resources, or advances in knowledge or technology subsequent to publication of the guidelines.

The practice of medicine includes both the art and the science of the prevention, diagnosis, alleviation, and treatment of disease. The variety and complexity of human conditions make it impossible to always reach the most appropriate diagnosis or to predict with certainty a particular response to treatment.

Therefore, it should be recognized that adherence to these guidelines will not ensure an accurate diagnosis or a successful outcome. All that should be expected is that the practitioner will follow a reasonable course of action based on current knowledge, available resources, and the needs of the patient to deliver effective and safe medical care. The sole purpose of these guidelines is to assist practitioners in achieving this objective.

Modeling PET Data Acquired During Nonsteady Conditions: What If Brain Conditions Change During the Scan?

Researchers use dynamic PET imaging with target-selective tracer molecules to probe molecular processes. Kinetic models have been developed to describe these processes. The models are typically fitted to the measured PET data with the assumption that the brain is in a steady-state condition for the duration of the scan. The end results are quantitative parameters that characterize the molecular processes. The most common kinetic modeling endpoints are estimates of volume of distribution or the binding potential of a tracer. If the steady state is violated during the scanning period, the standard kinetic models may not apply. To address this issue, time-variant kinetic models have been developed for the characterization of dynamic PET data acquired while significant changes (e.g., short-lived neurotransmitter changes) are occurring in brain processes. These models are intended to extract a transient signal from data. This work in the PET field dates back at least to the 1990s. As interest has grown in imaging nonsteady events, development and refinement of time-variant models has accelerated. These new models, which we classify as belonging to the first, second, or third generation according to their innovation, have used the latest progress in mathematics, image processing, artificial intelligence, and statistics to improve the sensitivity and performance of the earliest practical time-variant models to detect and describe nonsteady phenomena. This review provides a detailed overview of the history of time-variant models in PET. It puts key advancements in the field into historical and scientific context. The sum total of the methods is an ongoing attempt to better understand the nature and implications of neurotransmitter fluctuations and other brief neurochemical phenomena.
