Africa in 2023: Continuing political and economic volatility Expert comment NCapeling 6 January 2023

Despite few African trade and financial links with Russia and Ukraine, the war in Ukraine will cause civil strife in Africa due to food and energy inflation.

Africa’s economy was recovering from the COVID-19 pandemic in 2022 when a range of internal and external shocks struck such as adverse weather conditions, a devastating locust invasion, and the Russian invasion of Ukraine – all of which worsened already rapidly-rising rates of inflation and borrowing costs.

Although the direct trade and financial linkages of Africa with Russia and Ukraine are small, the war has damaged the continent’s economies through higher commodity prices, higher food, fuel, and headline inflation.

The main impact is on the increasing likelihood of civil strife because of food and energy-fuelled inflation amid an environment of heightened political instability.

Key African economies such as South Africa and Nigeria were already stuck with low growth and many African governments have seen their debt burdens increase – some such as Ethiopia and Ghana now have dollar debt trading at distressed levels – and more countries will follow in 2023.

On average the public sector debt-to-GDP ratio of African countries stood at above 60 per cent in 2022. The era of Chinese state-backed big loans and mega-projects which started 20 years ago in Angola after the end of its civil war may be coming to an end but Chinese private sector investments on the continent will continue through its Belt and Road Initiative and dual circulation model of development.

Great and middle powers building influence

Geopolitical competition in Africa has intensified in 2022, particularly among great powers such as China, Russia, the US, and the EU but also by middle powers such as Turkey, Japan, and the Gulf states.

The sixth AU-EU summit held in Brussels in February 2022 agreed on the principles for a new partnership, although the Russian invasion of Ukraine which followed disrupted these ambitions. Japan’s pledge of $30 billion in aid for Africa at TICAD 8 in August 2022 was clearly made due to the $40 billion pledged at the China–Africa summit in November 2021.

The US also launched a new strategy to strengthen its partnership and held a second US-Africa Leaders’ summit in Washington in December, the first since 2014. Russia’s ambition has been curtailed by its invasion of Ukraine, postponing its second summit with African states to 2023.

The imposition of international sanctions complicated its trade and investments, and military support such as that provided by Russian paramilitary group Wagner focused on Mali, Libya and the Central African Republic (CAR) has been curtailed.

The strategic importance of Africa has resulted in all the UN P5 members calling on the G20 to make the African Union (AU) its 21st member in 2023 under India’s presidency.

International competition to secure Africa’s critical and strategic minerals and energy products intensified in 2022 and, in the energy sector, European countries are seeking to diversify away from Russian oil and gas with alternative supplies, such as those from Africa.

Western mining companies and commodity traders are also increasingly seeking alternative supplies from Africa. Decarbonization is becoming a driver of resource nationalism and geopolitical competition in certain African mining markets, home to large deposits of critical ‘transition minerals’ such as copper, cobalt, graphite, lithium, or nickel.

COP27 was hosted in Egypt in November and gave African leaders an opportunity to shape climate discussions by pushing priority areas such as loss and damage, stranded assets, access to climate finance, adaptation, and desertification. Climate adaptation in Africa is a key condition to preserving economic growth and maintaining social cohesion.

The Horn of Africa, particularly Somalia, is suffering from one of the worst droughts in memory. The geopolitical and geoeconomic ramifications of the war in Ukraine has directly impacted the African continent by contributing to food and cooking oil inflation and humanitarian aid delivery.

Thoughout 2022 the AU was undergoing intensive reform and it struggled to respond to the growing number of security crises across the continent. Hotspots in 2023 will be in the western Sahel and Lake Chad Basin, eastern DRC, and northern Mozambique, all of them crossing state borders.

In Mozambique, a 2019 peace deal assisted by the United Nations (UN) will see the last ex-guerrillas from Renamo demobilized in 2023 to reintegrate into civilian life – some having been recruited in 1978.

In eastern Congo, M23 – one of around 120 armed groups – resumed its conflict against the central government. After lying dormant for several years, it took up arms again in 2021 and has been leading an offensive in eastern DRC against the Congolese army.

According to the UN, Rwanda has been supporting M23, and Kenya’s parliament approved in November the deployment of about 900 soldiers to the DRC as part of a joint military force from the East African Community (EAC) bloc – DRC joined the EAC in March.

In the Horn of Africa, Ethiopia saw an uneasy ceasefire agreed between the federal government and the Tigray People’s Liberation Front (TPLF).

Islamist militant groups in Africa further expanded their territorial reach in 2022, particularly in the western Sahel where al-Qaeda and Islamic State affiliates are competing for influence and continued to make inroads.

The drawdown and exit of western forces from Mali, both the French Operation Barkane and international contributions for the UN’s MINUSMA mission there, adds new dimensions to regional security challenges.

Mali’s decision in May to withdraw from the G5 Sahel has also eroded the regional security architecture. Jihadist activity may spread further into coastal states which has resulted in international partners such as France and the UK redesigning their security assistance strategies for the region.

Coups on the increase again

Since 2020, there have been successful military coups in Burkina Faso (twice), Chad, Guinea, Mali (twice), and Sudan, and failed ones in the CAR, Djibouti, Guinea-Bissau, Madagascar, Niger, and possibly Gambia and São Tomé and Príncipe.

Three national elections illustrate the state of African democracy in 2022. In Angola’s August elections, the ruling MPLA lost its absolute majority with the opposition UNITA winning the majority in Luanda for the first time.

Special Report

Amyloid fibrils are polymeric structures originating from aggregation of misfolded proteins. In vivo, proteolysis may modulate amyloidogenesis and fibril stability. In light chain (AL) amyloidosis, fragmented light chains (LCs) are abundant components of amyloid deposits; however, site and timing of proteolysis are debated. Identification of the N and C termini of LC fragments is instrumental to understanding involved processes and enzymes. We investigated the N and C terminome of the LC proteoforms in fibrils extracted from the hearts of two AL cardiomyopathy patients, using a proteomic approach based on derivatization of N- and C-terminal residues, followed by mapping of fragmentation sites on the structures of native and fibrillar relevant LCs. We provide the first high-specificity map of proteolytic cleavages in natural AL amyloid. Proteolysis occurs both on the LC variable and constant domains, generating a complex fragmentation pattern. The structural analysis indicates extensive remodeling by multiple proteases, largely taking place on poorly folded regions of the fibril surfaces. This study adds novel important knowledge on amyloid LC processing: although our data do not exclude that proteolysis of native LC dimers may destabilize their structure and favor fibril formation, the data show that LC deposition largely precedes the proteolytic events documentable in mature AL fibrils.

A comprehensive and standardized system to report lipid structures analyzed by MS is essential for the communication and storage of lipidomics data. Herein, an update on both the LIPID MAPS classification system and shorthand notation of lipid structures is presented for lipid categories Fatty Acyls (FA), Glycerolipids (GL), Glycerophospholipids (GP), Sphingolipids (SP), and Sterols (ST). With its major changes, i.e., annotation of ring double bond equivalents and number of oxygens, the updated shorthand notation facilitates reporting of newly delineated oxygenated lipid species as well. For standardized reporting in lipidomics, the hierarchical architecture of shorthand notation reflects the diverse structural resolution powers provided by mass spectrometric assays. Moreover, shorthand notation is expanded beyond mammalian phyla to lipids from plant and yeast phyla. Finally, annotation of atoms is included for the use of stable isotope-labeled compounds in metabolic labeling experiments or as internal standards. This update on lipid classification, nomenclature, and shorthand annotation for lipid mass spectra is considered a standard for lipid data presentation.

Recent efforts in gut microbiome studies have highlighted the importance of explicitly describing the ecological processes beyond correlative analysis. However, we are still at the early stage of understanding the organizational principles of the gut ecosystem, partially because of the limited information provided by currently used analytical tools in ecological modeling practices. Proteomics and metaproteomics can provide a number of insights for ecological studies, including biomass, matter and energy flow, and functional diversity. In this Mini Review, we discuss proteomics and metaproteomics-based experimental strategies that can contribute to studying the ecology, in particular at the mucosal-luminal interface (MLI) where the direct host-microbiome interaction happens. These strategies include isolation protocols for different MLI components, enrichment methods to obtain designated array of proteins, probing for specific pathways, and isotopic labeling for tracking nutrient flow. Integration of these technologies can generate spatiotemporal and site-specific biological information that supports mathematical modeling of the ecosystem at the MLI.

Renal Cell Carcinoma (RCC) is one of the most commonly diagnosed cancers worldwide with research efforts dramatically improving understanding of the biology of the disease. To investigate the role of the immune system in treatment-naïve clear cell Renal Cell Carcinoma (ccRCC), we interrogated the immune infiltrate in patient-matched ccRCC tumor samples, benign normal adjacent tissue (NAT) and peripheral blood mononuclear cells (PBMCs isolated from whole blood, focusing our attention on the myeloid cell infiltrate. Using flow cytometric, MS, and ExCYT analysis, we discovered unique myeloid populations in PBMCs across patient samples. Furthermore, normal adjacent tissues and ccRCC tissues contained numerous myeloid populations with a unique signature for both tissues. Enrichment of the immune cell (CD45⁺) fraction and subsequent gene expression analysis revealed a number of myeloid-related genes that were differentially expressed. These data provide evidence, for the first time, of an immunosuppressive and pro-tumorigenic role of myeloid cells in early, clinically localized ccRCC. The identification of a number of immune proteins for therapeutic targeting provides a rationale for investigation into the potential efficacy of earlier intervention with single-agent or combination immunotherapy for ccRCC.

Endometrial carcinoma (EC) is the most common gynecologic malignancy in the United States, with limited effective targeted therapies. Endometrial tumors exhibit frequent alterations in protein kinases, yet only a small fraction of the kinome has been therapeutically explored. To identify kinase therapeutic avenues for EC, we profiled the kinome of endometrial tumors and normal endometrial tissues using Multiplexed Inhibitor Beads and Mass Spectrometry (MIB-MS). Our proteomics analysis identified a network of kinases overexpressed in tumors, including Serine/Arginine-Rich Splicing Factor Kinase 1 (SRPK1). Immunohistochemical (IHC) analysis of endometrial tumors confirmed MIB-MS findings and showed SRPK1 protein levels were highly expressed in endometrioid and uterine serous cancer (USC) histological subtypes. Moreover, querying large-scale genomics studies of EC tumors revealed high expression of SRPK1 correlated with poor survival. Loss-of-function studies targeting SRPK1 in an established USC cell line demonstrated SRPK1 was integral for RNA splicing, as well as cell cycle progression and survival under nutrient deficient conditions. Profiling of USC cells identified a compensatory response to SRPK1 inhibition that involved EGFR and the up-regulation of IGF1R and downstream AKT signaling. Co-targeting SRPK1 and EGFR or IGF1R synergistically enhanced growth inhibition in serous and endometrioid cell lines, representing a promising combination therapy for EC.

This article has been withdrawn by the authors. We discovered an error after this manuscript was published as a Paper in Press. Specifically, we learned that the structures of glycans presented for the PD-L1 peptide were drawn and labeled incorrectly. We wish to withdraw this article and submit a corrected version for review.

Glycosylation is a highly diverse set of co- and post-translational modification of proteins. For mammalian glycoproteins, glycosylation is often site-, tissue- and species-specific, and diversified by microheterogeneity. Multitudinous biochemical, cellular, physiological and organismic effects of their glycans have been revealed, either intrinsic to the carrier proteins or mediated by endogenous reader proteins with carbohydrate recognition domains. Furthermore, glycans frequently form the first line of access by or defense from foreign invaders, and new roles for nucleocytoplasmic glycosylation are blossoming. We now know enough to conclude that the same general principles apply in invertebrate animals and unicellular eukaryotes – different branches of which spawned the plants or fungi and animals. The two major driving forces for exploring the glycomes of invertebrates and protists are (i) to understand the biochemical basis of glycan-driven biology in these organisms, especially of pathogens, and (ii) to uncover the evolutionary relationships between glycans, their biosynthetic enzyme genes, and biological functions for new glycobiological insights. With an emphasis on emerging areas of protist glycobiology, here we offer an overview of glycan diversity and evolution, to promote future access to this treasure trove of glycobiological processes.

Aspergillus flavus (A. flavus), a pathogenic fungus, can produce carcinogenic and toxic aflatoxins that are a serious agricultural and medical threat worldwide. Attempts to decipher the aflatoxin biosynthetic pathway have been hampered by the lack of a high-quality genome annotation for A. flavus. To address this gap, we performed a comprehensive proteogenomic analysis using high-accuracy mass spectrometry data for this pathogen. The resulting high-quality dataset confirmed the translation of 8,724 previously-predicted genes, and identified 732 novel proteins, 269 splice variants, 447 single amino acid variants, 188 revised genes. A subset of novel proteins was experimentally validated by RT-PCR and synthetic peptides. Further functional annotation suggested that a number of the identified novel proteins may play roles in aflatoxin biosynthesis and stress responses in A. flavus. This comprehensive strategy also identified a wide range of post-translational modifications (PTMs), including 3,461 modification sites from 1,765 proteins. Functional analysis suggested the involvement of these modified proteins in the regulation of cellular metabolic and aflatoxin biosynthetic pathways. Together, we provided a high quality annotation of A. flavus genome and revealed novel insights into the mechanisms of aflatoxin production and pathogenicity in this pathogen.

The histopathological subtype of lung adenocarcinoma (LUAD) is closely associated with prognosis. Micropapillary or solid predominant LUAD tends to relapse after surgery at an early stage, whereas lepidic pattern shows a favorable outcome. However, the molecular mechanism underlying this phenomenon remains unknown. Here, we recruited 31 lepidic predominant LUADs (LR: low-risk subtype group) and 28 micropapillary or solid predominant LUADs (HR: high-risk subtype group). Tissues of these cases were obtained and label-free quantitative proteomic and bioinformatic analyses were performed. Additionally, prognostic impact of targeted proteins was validated using The Cancer Genome Atlas databases (n=492) and tissue microarrays composed of early-stage LUADs (n=228). A total of 192 differentially expressed proteins were identified between tumor tissues of LR and HR and three clusters were identified via hierarchical clustering excluding eight proteins. Cluster 1 (65 proteins) showed a sequential decrease in expression from normal tissues to tumor tissues of LR and then to HR and was predominantly enriched in pathways such as tyrosine metabolism and ECM-receptor interaction, and increased matched mRNA expression of 18 proteins from this cluster predicted favorable prognosis. Cluster 2 (70 proteins) demonstrated a sequential increase in expression from normal tissues to tumor tissues of LR and then to HR and was mainly enriched in pathways such as extracellular organization, DNA replication and cell cycle, and high matched mRNA expression of 25 proteins indicated poor prognosis. Cluster 3 (49 proteins) showed high expression only in LR, with high matched mRNA expression of 20 proteins in this cluster indicating favorable prognosis. Furthermore, high expression of ERO1A and FEN1 at protein level predicted poor prognosis in early-stage LUAD, supporting the mRNA results. In conclusion, we discovered key differentially expressed proteins and pathways between low-risk and high-risk subtypes of early-stage LUAD. Some of these proteins could serve as potential biomarkers in prognostic evaluation.

Libya’s War Economy: Predation, Profiteering and State Weakness Research paper sysadmin 9 April 2018

As Libya’s war economy persists, prospects for the restoration of functioning central governance become more distant.

Summary

• Libya suffers from interlinked political, security and economic crises that are weakening state institutions, damaging its economy and facilitating the continued existence of non-state armed groups. As rival authorities continue to compete for power, the resulting fragmentation and dysfunction have provided a fertile environment for the development of a pervasive war economy dependent on violence.
• This war economy is dynamic and constantly in flux. Relative to earlier problems, there were signs of progress on several fronts in 2017: a reduction in human smuggling, a tripling in oil revenues, and increased local action against fuel smuggling. Yet the dynamics that have supported the war economy’s rise remain.
• Libya’s war economy is highly damaging for the future of the state for three reasons:
  • First, it provides an enabling environment for networks of armed groups, criminal networks, corrupt businessmen and political elites to sustain their activities through illicit sales and predatory practices. Their operations are closely linked to the dispensation of violence, and are thus a spur for further conflict.
  • Second, the war economy perpetuates negative incentives for those who profit from the state’s dysfunction. Only effective governance, supported by a durable political settlement, can tackle the foundations of Libya’s war economy. But neither a return to functioning central governance nor the development of a security sector that is fit for purpose is in the interests of war economy profiteers, who are therefore motivated to act as powerful spoilers of reform.
  • Third, the political contestation and resource predation practised by those engaged in the war economy are having a disastrous impact on Libya’s formal economy, undermining what remains of its institutions. As the war economy persists, therefore, the prospects for the restoration of functioning central governance become more distant. This threatens to create a vicious cycle that accelerates further state collapse.
• Due to the limited capacity for coercion available to any actor or entity connected with the state, a strategy of co-opting networks of war economy profiteers has almost exclusively prevailed. This has failed. Drawing on the lessons from these attempts, a more successful policy must pursue targeted measures to combat the enabling structures of Libya’s war economy where possible, and to co-opt war economy profiteers only where necessary.
• In this, state authorities can do more to utilize what power they have to name and shame war economy profiteers in order to weaken the local legitimacy critical to profiteers’ survival. The state must present credible alternative livelihood opportunities to those engaged in, or benefiting from, the war economy. Progress will depend in part on the creation of positive incentives to abandon such activity. Where profiteers cannot be incentivized to move towards more legitimate economic activities, greater and more effective efforts must be made to reduce the profit margins of illicit schemes.
• The international community can do more to support Libyan efforts in countering the war economy. Cooperation over the targeting of criminal groups’ overseas assets, support for increased transparency over the dispensation of state funds, and measures to reduce the viability of illicit activities can all help to strengthen the position of state authorities.

Tackling Illegal Wildlife Trade in Africa: Economic Incentives and Approaches Research paper sysadmin 5 October 2018

Combating illegal wildlife trade and further pursuing conservation-development models could help generate considerable economic benefits for African countries, while ensuring the long-term preservation of Africa’s wealth of natural capital.

Summary

• The illegal wildlife trade (IWT) significantly impacts African economies by destroying and corroding natural, human and social capital stocks. This hinders the achievement of the Sustainable Development Goals (SDGs) and has an impact on national budgets. Illicit financial flows from IWT deny revenue to governments where legal wildlife product trade exists and perpetuate cash externalization. IWT diverts national budgets away from social or development programmes, increases insecurity and threatens vulnerable populations.
• In expanding wildlife economies and pursuing conservation-driven development models, governments can protect their citizens, derive revenue from wildlife products, and establish world class tourism offerings. The illegal exploitation of wildlife is often due to a failure to enforce rights over those resources, where rights are unclearly defined or not fully exercised. Southern African countries have defined these rights in various ways, contributing to regional differences in conservation practices and the socio-economic benefits derived from wildlife resources. Combating IWT is an important step towards allowing legitimate business and communities to develop livelihoods that incentivize stewardship and connect people to conservation.
• The Southern African Development Community (SADC) has several framework policies for the establishment of transfrontier conservation areas (TFCAs). These promote local stewardship across multiple land-use areas to conserve biodiversity and increase the welfare and socioeconomic development of rural communities. Private-sector partnerships also increase skills transfer, improve access to investment finance, and expand economic opportunities, including through the promotion of local procurement. The economic benefits of TFCAs extend beyond tourism.
• The economic value of African ecosystems is often under-recognized because they remain unquantified, partly due to the lack of available data on the broader economic costs of IWT. Improved monitoring and evaluation with key performance indicators would help governments and citizens to appreciate the economic value of combating IWT.

In nucleotide excision repair, bulky DNA lesions such as UV-induced cyclobutane pyrimidine dimers are removed from the genome by concerted dual incisions bracketing the lesion, followed by gap filling and ligation. So far, two dual-incision patterns have been discovered: the prokaryotic type, which removes the damage in 11–13-nucleotide-long oligomers, and the eukaryotic type, which removes the damage in 24–32-nucleotide-long oligomers. However, a recent study reported that the UvrC protein of Mycobacterium tuberculosis removes damage in a manner analogous to yeast and humans in a 25-mer oligonucleotide arising from incisions at 15 nt from the 3´ end and 9 nt from the 5´ end flanking the damage. To test this model, we used the in vivo excision assay and the excision repair sequencing genome-wide repair mapping method developed in our laboratory to determine the repair pattern and genome-wide repair map of Mycobacterium smegmatis. We find that M. smegmatis, which possesses homologs of the Escherichia coli uvrA, uvrB, and uvrC genes, removes cyclobutane pyrimidine dimers from the genome in a manner identical to the prokaryotic pattern by incising 7 nt 5´ and 3 or 4 nt 3´ to the photoproduct, and performs transcription-coupled repair in a manner similar to E. coli.

Rebuilding Zimbabwe's Economy: Emmerson Mnangagwa’s Immediate Priorities Expert comment sysadmin 13 December 2017

Zimbabwe cannot expect to rebuild in the same economic model that brought previous prosperity.

Returning to Harare as Zimbabwe’s president-designate Emmerson Mnangagwa declared, ‘We want to grow our economy, we want peace, we want jobs, jobs, jobs.’

Robert Mugabe leaves a legacy of an independent Zimbabwe in a deep economic crisis. Much remains uncertain as to what a new government in Zimbabwe will look like, and there is sure to be continuity as well as considerable change.

What is clear is that a new administration under Mnangagwa will need to turn the economy around to garner support and legitimacy from the Zimbabwean people. Zimbabwe’s economic output halved over the period 1997–2008, and it has not recovered. With more than 80 per cent of Zimbabweans in the informal economy, and with social and economic resilience undermined by previous crises and decades of mismanagement, the stakes for the new leader are very high.

Reform will be difficult particularly because politically connected elites have acquired businesses through uncompetitive means. They will be reluctant to see significantly more competition. But they will also want an improved economic environment. And there is scope for the people of Zimbabwe to benefit from this.

An important change will be in the prioritization of economic stability. Mugabe demonstrated that he was willing to make political decisions irrespective of the economic consequences. Mnangagwa is thought to be less ideological and more of a pragmatist. For him, delivering economic recovery will be crucial to building political support.

The most pressing fiscal priority is the public wage bill. Employment costs account for over 80 per cent of government expenditure, crowding out spending on social programmes, health and education. But the fragility of the economy means that reform cannot be fast-tracked. The public wage bill accounts for over 20 per cent of GDP and is an essential driver of demand. Public sector workers are also politically influential. Another further priority is the reform of state-owned enterprises that are pressuring the fiscus.

A new administration will need to rebuild confidence. Policymakers have been operating in a low-confidence environment for a long time, but for any meaningful change to take root there has to be trust between the government, businesses and the people of Zimbabwe. Businesses and citizens will want to see a plan of action for remonetizing the economy. Zimbabwe faces an acute liquidity crisis. A shortage of US dollars and a lack of confidence in government-issued bond notes are testing resilience.

The financial system has recovered from a crisis of nonperforming loans – triggered by high debt amassed during the post-dollarization boom, and weak corporate governance. But the system remains highly fragile and swamped with government debt. Hard cash US dollar deposits fell from 49 per cent ($582 million) in 2009 to just six per cent ($269 million) in 2016. In 2015, industrial utilization stood at just 34.3 per cent of installed capacity, and it was estimated that just five per cent of the country’s businesses were viable.

The crux of the Zimbabwean economy is the linkage between agriculture and manufacturing. Commercial agriculture contributes approximately 12 per cent of the country’s GDP, and more than 60 per cent of inputs into the manufacturing sector. Tobacco in particular is a vital earner of much needed foreign exchange. Policies to support mid-scale farmers will have multiplier effects. They drive agricultural growth and generate jobs throughout the supply chain.

Zimbabwe also has world-class natural resource endowments including ferrochrome, gold, copper, iron ore, lithium, diamonds and platinum group metals. But longer investment-gestation periods and industry risk adversity will mean that payoffs from fresh investments in this sector will take longer to materialize.

Domestic finance will need to be mobilized to generate recovery, and this will need to be supported by international investment. But international investors entering the country must be cognizant of Zimbabwean’s expectations and also historical perceptions – especially around the scepticism of neoliberal economics as a result of failed structural adjustment programmes in the 1990s.

Zimbabweans have high social expectations for international investors. Educated, tech-savvy, internationally connected youth are at the core of the consumer class that investors will be targeting, to both sell products to but also to staff offices in country. But this cohort also has a greater expectation of international companies to adhere to the norms and standards that they abide by at home and not take advantage of weak governance or poor regulation to exploit citizens.

Investors in Zimbabwe must also recognize that behind the controversial Mugabe policies of land reform and indigenization – the empowerment of local citizens through shared ownership – was a popular desire for postcolonial economic transformation. This sentiment remains. Working in partnership with local entities and communicating the economic contribution made to society will be necessary to build a long-term presence in Zimbabwe, and reap the dividend of what many hope to be a new start for the country.

Fresh thinking is required from domestic policymakers and international partners. A skilled population and estimated 3-5 million-strong diaspora will bring international experience and make a considerable contribution to this process. Some of this thinking has been done. The Lima process of re-engagement with international financial institutions that was agreed at the end of 2015 has laid some of the groundwork, especially around international expectations regarding both economic and governance reform – the substance of which was analysed in a 2016 Chatham House paper. The implementation of recommendations of the well-regarded auditor-general’s report on SOE reform will also be a key prerequisite for long-term reform.

Zimbabweans are not alone in processing what has happened and how to react. Investors have long been poised to capitalize on what is perceived to be one of the continent’s best long-term prospects. A lot will remain unchanged following the transition. But significantly, for the first time in decades, there is a real opportunity to effect positive change and improve the livelihoods of millions of Zimbabweans.

Zimbabwe Ahead of the Elections: Political and Economic Challenges 8 May 2018 — 10:00AM TO 11:00AM Anonymous (not verified) 3 May 2018 Chatham House, London

The upcoming elections in Zimbabwe will be the first since 2000 in which former president Robert Mugabe and long-time opposition leader Morgan Tsvangirai are not on the ballot paper. A key electoral issue for many voters will be the economy: recent years have been marked by high unemployment rates, chronic cash shortages and mounting public debt. Although this has traditionally been a strong campaigning issue for the opposition, President Emmerson Mnangagwa has fast-tracked comprehensive economic reforms.

At this event, Nelson Chamisa, MDC Alliance presidential candidate, will discuss his efforts to build a united opposition coalition with a strong message, the steps needed to ensure a free and fair election can take place, and the role that international partners can play in Zimbabwe’s democratic process.

Improving Economic Management for Sustainable Growth in Zambia 13 July 2018 — 9:00AM TO 10:00AM Anonymous (not verified) 19 June 2018 Chatham House, London

THIS EVENT IS POSTPONED.

High levels of infrastructure investment funded by commercial loans, against a backdrop of subdued economic growth, resulted in an increase in Zambia’s public external debt from $8.7 billion in 2017 to $9.3 billion in March 2018.

In June 2018 Zambia’s Ministry of Finance announced new austerity measures aimed at reducing the country’s debt burden, as part of an ongoing reform agenda that is hoped to stabilise the economy.

In the meantime Zambia grapples with severe social and development challenges. Decreased spending in health, education and social protection, and poor access in rural areas, have already left Zambia ranked 139th out of 188 countries in the UNDP’s 2016 human development index.

At this meeting Margaret Mwanakatwe, minister of finance, discusses the government’s financial reform agenda, its engagement with creditors and IFIs, and plans for generating sustainable growth and job creation.

Zimbabwe Futures 2030: A Vision for Inclusive Long-Term Economic Recovery 10 October 2019 — 10:00AM TO 12:15PM Anonymous (not verified) 5 September 2019 Harare, Zimbabwe

In its Vision 2030, the government of Zimbabwe committed itself to facilitating an open market and stable economy through strategies such as the Transitional Stabilization Programme (TSP) and new industrialization policy. The private sector is pivotal to these objectives and creating an environment conducive to inclusive and job-creating economic growth. Economic growth can only be achieved with a conducive policy environment and government support to underpin markets with provision of public goods, entrepreneurial incentives and protect contract enforcement and dispute resolution mechanisms.

This event will launch a new Chatham House Africa Programme publication on Zimbabwe’s Vision 2030. The paper is the culmination of an inclusive research process that has drawn on senior private sector expertise, civil society, academics, technocratic elements of government and other experts to develop policy recommendations that will support inclusive economic growth in Zimbabwe.

This event is held in partnership with the Zimbabwe Business Club and Konrad Adenauer Stiftung (KAS). It is supported by KAS and the Dulverton Trust.

Economic Recovery and Anticorruption in South Africa: Assessing Progress on the Reform Agenda 4 December 2019 — 3:00PM TO 4:00PM Anonymous (not verified) 25 November 2019 Chatham House | 10 St James's Square | London | SW1Y 4LE

South Africa has significant economic potential based on its resource endowment, quality human capital and well-developed infrastructure compared to the region. However, the country’s economic growth rate has not topped 2 per cent since 2013, and in 2018, was below 1 per cent. This has put a strain on citizens and communities in a country that still suffers from structural inequality, poverty and high unemployment. Economic recovery and anti-corruption were the central pillars of President Cyril Ramaphosa’s 2019 electoral campaign and he has set an investment target of $100 billion. However, voters and investors alike are demanding faster and more visible progress from the country’s enigmatic leader who has a reputation for caution and calculation.

POSTPONED: Pursuing Economic Reform and Growth in South Africa: the view from the African National Congress 18 March 2020 — 10:30AM TO 11:30AM Anonymous (not verified) 3 March 2020 Chatham House | 10 St James's Square | London | SW1Y 4LE

The government of South Africa is pursuing a programme of reform to revitalize the economy, strengthen institutions and combat corruption. The State of the Nation Address (SONA) on 13 February and the budget speech of 26 February represent the most significant articulation of the government’s economic strategy. Central to this is the government’s plans for the energy sector, which is fundamental for reviving the economy, and the reform of State Owned Enterprises (SOEs). But questions remain about possible divergence of the approach taken by government ministers from the policy position of the ruling party, the African National Congress (ANC), and what this might mean for the sustainability and progress of reform.

At this event, Paul Mashatile, Treasurer General of the ANC, will discuss the party’s assessment of reform efforts to date and priorities for delivering on inclusive growth.

PLEASE NOTE THIS EVENT IS POSTPONED UNTIL FURTHER NOTICE.

Webinar: South Africa's Economic Recovery Beyond COVID-19 27 May 2020 — 1:00PM TO 2:00PM Anonymous (not verified) 18 May 2020

South Africa's Economic Outlook 20 August 2020 — 12:00PM TO 1:00PM Anonymous (not verified) 11 August 2020 Online

South Africa’s long mooted economic reforms have been slow to materialize. The economy had fallen into recession even before the COVID-19 pandemic, and had been stripped of its international investment grade rating. The reserve bank is now forecasting a contraction in GDP of over seven percent for 2020.

There are significant questions around the role of the state in the economy, the level of intervention, and its affordability, with key government figures sceptical of rapid market reforms. The mandate and independence of the South African Reserve Bank has also been a subject of public debate. The IMF has approved a US$4.3 billion emergency financial assistance package to help mitigate the health and economic shock to the country. But it has also made clear that there is a pressing need to ensure debt sustainability and implement structural reforms to support recovery and achieve sustainable and inclusive growth.

At this event, Lesetja Kganyago, the governor of the South African Reserve Bank (SARB), gives his assessment of the expected trajectory of the South African economy in the short and medium term. He discusses the IMF package and the implications for economic reform, and the role of the reserve bank in delivering sustainable and inclusive growth.

Zimbabwe's Economy During the Coronavirus Pandemic and Beyond 8 September 2020 — 10:00AM TO 11:30AM Anonymous (not verified) 26 August 2020

COVID-19 has had a devastating effect on Zimbabwe’s already floundering economy. Important foreign currency earning industries have virtually stopped, and across the country livelihoods are at risk and an increasing number of people are reliant on government grants.

Businesses are having to become more flexible but are constrained by a weak policy environment and lack of confidence in the economy. Since 2017, the government has been pursuing an economic reform agenda and Transitional Stabilization Programme (TSP), which was scheduled for completion by the end of 2020. The deepening challenges highlight the need to accelerate economic reform and build confidence in order to achieve sustainable and inclusive growth.

At this webinar, speakers discuss the measures that government, businesses, and individuals are adopting in response to the COVID-19 economic challenge, and the policies required for recovery.

South Africa's Economic Reform and Employment in the Context of the Coronavirus Pandemic 3 September 2020 — 3:00PM TO 4:00PM Anonymous (not verified) 26 August 2020 Online

President of COSATU, Zingiswa Losi, discusses the organization’s priorities for protecting jobs and workers, and working with other stakeholders to build a sustainable post-pandemic economy.

Employment in South Africa fell by an estimated 18 per cent between February and April 2020. The measures imposed to control the spread of COVID-19 suffocated an already weak economy and unemployment has hit a new high.

The stated aims of the government’s economic reform plans include the support of job creation in labour intensive industries, but the reform of the state and rebalancing of the economy and fiscus could lead to further job losses in state agencies and enterprises.

Protecting jobs while ensuring the health and safety of workers are dual priorities, and require the joint commitment and ‘social compact’ of labour, business and government.

Zimbabwe’s Economic Governance and Regional Integration 17 November 2020 — 12:00PM TO 1:30PM Anonymous (not verified) 6 November 2020 Online

Panellists discuss policy and governance for long-term economic prosperity in Zimbabwe, reflecting on the role of institutional change and regional integration in the context of the shocks caused by the coronavirus pandemic.

At this virtual event, panellists and participants will discuss policy and governance for long-term economic prosperity in Zimbabwe, reflecting on the role of institutional change and regional integration.

The government of Zimbabwe has emphasized its commitment to economic reform and its ambition to achieve upper-middle-income status by 2030, but there are considerable challenges to overcome.

The COVID-19 pandemic has exacerbated existing economic fragility. Improving the business climate to attract international private-sector investment will be contingent on clear, consistent and coherent policy and implementation, including targeting abuse and corruption.

Zimbabwe has, in recent years, successfully strengthened its regional trade integration, although some trade frictions remain. This is an important factor not only for catalysing economic growth in Zimbabwe, but for supporting regional prosperity and post-COVID recovery.

This webinar is the second in a series of events held in partnership with the Konrad Adenauer Stiftung on Zimbabwe’s economic reform and recovery.

Inclusion, agency and influence: The role of women in Zimbabwe’s economy 8 July 2021 — 3:00PM TO 4:30PM Anonymous (not verified) 2 July 2021 Online

Speakers discuss the changing role of women in Zimbabwe’s economic structures and the priorities for promoting greater economic inclusion, agency and influence of women.

Zimbabwe’s National Development Strategy of 2021-2025 highlights the importance of gender sensitivity in policymaking and of women’s economic participation in attaining the government’s Vision 2030.

However, women have been among the worst affected groups by the devastating effects that COVID-19 has had on Zimbabwe’s already floundering economy, which has exacerbated the challenges they face in economic life, such as access to credit, financial services and social security.

Leveraging existing structures such as women’s groups, micro-finance facilities, education and training, and national gender mechanisms, as well as supporting wider financial and digital inclusion in Zimbabwe, is central for the country’s sustained economic recovery.

This event also focuses on the differing impacts of COVID-19 on women’s economic activities across various sectors, as well as along rural-urban and formal-informal economy lines.

Angola Forum 2021: Policy options to support economic recovery in Angola 7 October 2021 — 2:00PM TO 5:00PM Anonymous (not verified) 22 September 2021 Online

Speakers discuss policy options to support economic recovery in Angola as the country transitions away from a state-led oil economy to a private-sector-led growth model.

The government of Angola has made some progress on a range of policies targeting macroeconomic stability and structural reform. However, the country has been suffering from a recurring economic recession for six consecutive years, with the last positive annual GDP growth rate posted in 2015 at 0.9 per cent.

The national budget remains dependent on oil revenue, leaving the country highly exposed to volatile oil prices particularly during the COVID-19 pandemic. While revenues collapsed, increased spending was needed to respond to the health crisis and estimates of Angola’s debt spike range from 130 to 150 per cent of its GDP by the close of 2020.

At this virtual Angola Forum, speakers discuss policy options to support economic recovery in Angola as the country transitions away from a state-led oil economy to a private-sector-led growth model.

The Forum launches the English translation of the Angola Economic Report 2019-20 by the Centro de Estudos de Investigação (CEIC) of the Catholic University of Angola in partnership with the Konrad-Adenauer-Stiftung (KAS), and the findings of Afrobarometer’s first ever survey in Angola, Ovilongwa – Estudos de Opinião Pública, which interviewed 2,400 adult Angolans and sampled individual perceptions on democracy and economic reform in Angola.

This event will be held in English and Portuguese with simultaneous interpretation.

The Forum will also be broadcast live on the Africa Programme Facebook page.

Zambia’s political and economic reform and recovery 5 November 2021 — 11:30AM TO 12:30PM Anonymous (not verified) 2 November 2021 Chatham House and Online

At this event, HE Hakainde Hichilema, president of the Republic of Zambia, discusses his vision for Zambia’s development and long-term political and economic reform and recovery.

Zambia’s new administration, following the general elections of August 2021, faces a daunting challenge of reversing economic contraction, lowering income-eroding inflation, and addressing the unsustainable national debt.

The country has been one of the few to seek debt restructuring under the G20’s new Common Framework for Debt Treatments, and its immediate priorities include a prospective agreement with the International Monetary Fund (IMF).

Young Zambians are eager for jobs and improved living standards. But the government’s ambition to create more jobs and achieve middle-income status will depend on both attracting new investment into its copper sector and pursuing a programme of economic diversification supporting growth beyond the mining industry.

Addressing these economic concerns will also need to be supported by a programme of political reform and rehabilitation of citizens’ trust in the state.

Angola forum 2022: Prospects for Angola's social and economic future 15 December 2022 — 1:00PM TO 4:30PM Anonymous (not verified) 28 November 2022 Online

At this online Angola forum, experts will discuss Angola’s social and economic future, and what to expect from 2023.

At this virtual Angola Forum, speakers will discuss Angola’s social and economic future and what to expect from 2023.

Angola experienced positive economic momentum in 2022 allowing it to exit its six-year recession, with the economy taking centre stage in the August national multiparty elections. Increased oil prices and high levels of production have driven Angola’s economic growth and improved macroeconomic conditions, as well as helping the country to reduce its public debt to 56.5 per cent of Gross Domestic Product (down from 79.7 per cent in 2021).

However, a global economic downturn in 2023, with increased inflation, means Angola’s re-elected MPLA government will need to focus on job creation, greater economic inclusivity and diversifying away from an oil-led economy. It will also require Angola to navigate its international partnerships more effectively in this era of heightened geopolitical rivalries.  

At this online Angola forum, experts will discuss Angola’s social and economic future and what to expect from 2023. Speakers will reflect on the social and economic trends seen in 2021-22 and explore election trends, human rights and international relations.

This Angola Forum is supported by the Konrad-Adenauer-Stiftung.

Nigeria's 2023 elections: Security, economic and foreign policy imperatives 5 December 2022 — 1:00PM TO 2:00PM Anonymous (not verified) 23 November 2022 Chatham House and Online

Bola Ahmed Tinubu, presidential candidate for the All-Progressives Congress, discusses his vision and recently-unveiled manifesto for ‘renewing hope’ in Nigeria.

Nigeria is scheduled to hold presidential and national assembly elections on 25 February 2023 as well as governorship and other subnational elections on 11 March 2023.

The elections will end President Muhammadu Buhari’s two terms in office since his election in 2015 and will mark the first time that he is not engaging in a presidential poll since Nigeria’s transition to civilian rule in 1999 – an important marker in Nigeria’s trajectory of democratic consolidation.

Nigeria’s recently enacted Electoral Act has contributed to improved hope around the election process, reflected in the addition of 12.29 million new voters in Nigeria’s voter registration exercise across the federation’s 36 states and 1,491 constituencies.

Yet Nigeria stands at a critical juncture, having suffered from two recessions in the past six years, unprecedented levels of food insecurity, persistent fuel scarcity and high levels of crude oil theft.

Civic fatigue also remains an important challenge and President Muhammadu Buhari’s three main policy pillars of security, economy and corruption continue to be defining issues for citizens.

At this event, Bola Ahmed Tinubu, presidential candidate for the All-Progressives Congress, discusses his vision and recently unveiled manifesto for ‘renewing hope’ in Nigeria including his policy proposals for economic reform and revival and how to deliver secure and inclusive job opportunities for Nigerian citizens.

Is China's economy on the rebound? 5 April 2023 — 6:00PM TO 7:00PM Anonymous (not verified) 28 February 2023 Chatham House and Online

Exploring the domestic and international signals from the first annual session of the 14th National People’s Congress.

2022 proved to be a difficult year for China. War, COVID-19 and economic turbulence presented a cocktail of significant challenges for the ruling CCP in China. Having dispensed of the infamous zero-COVID-19 policy, China is apparently back open for business.

On the international front, continued tensions with the West, war in Europe and climate change are just some of the obstacles standing in the way of Chinese economic recovery. 

Domestically, China must find ways to reinvigorate demand and move on from a low of 3 per cent GDP growth in 2022. With a frustrated population, people are also keen to be freed from the shackles of a stream of lockdowns and quarantining.

The in-tray for the 14th National People’s Congress, as it begins its first session, is substantial. The implications, at home and abroad, from its recent summit in Beijing reverberate around the world.

The experts on the panel discuss:

• What has been the true extent of COVID-related damage to China’s economy and wider society?
• What economic scars are visible post-recovery?
• Will there be longer-term implications for China’s economic and diplomatic footprint globally post-COVID? 

As with all member events, questions from the audience drive the conversation.

Radiolabeled small-molecule DOTA-haptens can be combined with antitumor/anti-DOTA bispecific antibodies (BsAbs) for pretargeted radioimmunotherapy (PRIT). For optimized delivery of the theranostic - and β-emitting isotope ¹⁷⁷Lu with DOTA-based PRIT (DOTA-PRIT), bivalent Gemini (DOTA-Bn-thiourea-PEG4-thiourea-Bn-DOTA, aka (3,6,9,12-tetraoxatetradecane-1,14-diyl)bis(DOTA-benzyl thiourea)) was developed. Methods: Gemini was synthesized by linking 2 S-2-(4-isothiocyanatobenzyl)-DOTA molecules together via a 1,14-diamino-PEG4 linker. [¹⁷⁷Lu]Lu-Gemini was prepared with no-carrier-added ¹⁷⁷LuCl₃ to a molar-specific activity of 123 GBq/μmol and radiochemical purity of more than 99%. The specificity of BsAb-¹⁷⁷Lu-Gemini was verified in vitro. Subsequently, we evaluated biodistribution and whole-body clearance for [¹⁷⁷Lu]Lu-Gemini and, for comparison, our gold-standard monovalent [¹⁷⁷Lu]Lu-S-2-(4-aminobenzyl)-DOTA ([¹⁷⁷Lu]Lu-DOTA-Bn) in naïve (tumor-free) athymic nude mice. For our proof-of-concept system, a 3-step pretargeting approach was performed with an established DOTA-PRIT regimen (anti-GPA33/anti-DOTA IgG-scFv BsAb, a clearing agent, and [¹⁷⁷Lu]Lu-Gemini) in mouse models. Results: Initial in vivo studies showed that [¹⁷⁷Lu]Lu-Gemini behaved similarly to [¹⁷⁷Lu]Lu-DOTA-Bn, with almost identical blood and whole-body clearance kinetics, as well as biodistribution and mouse kidney dosimetry. Pretargeting [¹⁷⁷Lu]Lu-Gemini to GPA33-expressing SW1222 human colorectal xenografts was highly effective, leading to absorbed doses of [¹⁷⁷Lu]Lu-Gemini for blood, tumor, liver, spleen, and kidneys of 3.99, 455, 6.93, 5.36, and 14.0 cGy/MBq, respectively. Tumor–to–normal tissue absorbed-dose ratios (i.e., therapeutic indices [TIs]) for the blood and kidneys were 114 and 33, respectively. In addition, we demonstrate that the use of bivalent [¹⁷⁷Lu]Lu-Gemini in DOTA-PRIT leads to improved TIs and augmented [¹⁷⁷Lu]Lu-Gemini tumor uptake and retention in comparison to monovalent [¹⁷⁷Lu]Lu-DOTA-Bn. Finally, we established efficacy in SW1222 tumor-bearing mice, demonstrating that a single injection of anti-GPA33 DOTA-PRIT with 44 MBq (1.2 mCi) of [¹⁷⁷Lu]Lu-Gemini (estimated tumor-absorbed dose, 200 Gy) induced complete responses in 5 of 5 animals and a histologic cure in 2 of 5 (40%) animals. Moreover, a significant increase in survival compared with nontreated controls was noted (maximum tolerated dose not reached). Conclusion: We have developed a bivalent DOTA-radiohapten, [¹⁷⁷Lu]Lu-Gemini, that showed improved radiopharmacology for DOTA-PRIT application. The use of bivalent [¹⁷⁷Lu]Lu-Gemini in DOTA-PRIT, as opposed to monovalent [¹⁷⁷Lu]Lu-DOTA-Bn, allows curative treatments with considerably less administered ¹⁷⁷Lu activity while still achieving high TIs for both the blood (>100) and the kidneys (>30).
