Webinar: Director's Briefing – National Leadership in Times of Crisis

Corporate Members Event Webinar Partners and Major Corporates

14 May 2020 - 6:00pm to 7:00pm
Add to Calendar

Online

Janet Napolitano, President, University of California; US Secretary of Homeland Security (2009-13)

Chair: Dr Robin Niblett, Director and Chief Executive, Chatham House

Across the globe, leaders on the local, national and international levels are grappling with the impacts of COVID-19 on their communities and the economy. But the coronavirus pandemic is just one of several existential crises the world is currently facing. Climate change, political instability and growing tensions with China and Russia, along with a lack of strong global leadership, has made it more difficult for individual nations to respond and coalesce in times of crisis.

This discussion will explore how leaders at all levels can best negotiate both the practical issues and the larger questions associated with these ‘grand challenges’. How is current US foreign policy affecting our collective ability to respond to issues such as pandemics or climate change? Has the COVID-19 crisis cemented the US retreat from global leadership and if so, who might step into the breach? How do we maintain momentum on other issues in the midst of a public health disaster of this magnitude? And what is the role of the business community, higher education institutions and other sectors in responding to these crises and shaping future public policy?

This event is only open to Major Corporate Member and Partner organizations and selected giving circles of Chatham House. If you'd like to attend, please RSVP to lbedford@chathamhouse.org.

Biophysical characterization of SARAH domain-mediated multimerization of Hippo pathway complexes in Drosophila [Signal Transduction]

Hippo pathway signaling limits cell growth and proliferation and maintains the stem-cell niche. These cellular events result from the coordinated activity of a core kinase cassette that is regulated, in part, by interactions involving Hippo, Salvador, and dRassF. These interactions are mediated by a conserved coiled-coil domain, termed SARAH, in each of these proteins. SARAH domain–mediated homodimerization of Hippo kinase leads to autophosphorylation and activation. Paradoxically, SARAH domain–mediated heterodimerization between Hippo and Salvador enhances Hippo kinase activity in cells, whereas complex formation with dRassF inhibits it. To better understand the mechanism by which each complex distinctly modulates Hippo kinase and pathway activity, here we biophysically characterized the entire suite of SARAH domain–mediated complexes. We purified the three SARAH domains from Drosophila melanogaster and performed an unbiased pulldown assay to identify all possible interactions, revealing that isolated SARAH domains are sufficient to recapitulate the cellular assemblies and that Hippo is a universal binding partner. Additionally, we found that the Salvador SARAH domain homodimerizes and demonstrate that this interaction is conserved in Salvador's mammalian homolog. Using native MS, we show that each of these complexes is dimeric in solution. We also measured the stability of each SARAH domain complex, finding that despite similarities at both the sequence and structural levels, SARAH domain complexes differ in stability. The identity, stoichiometry, and stability of these interactions characterized here comprehensively reveal the nature of SARAH domain–mediated complex formation and provide mechanistic insights into how SARAH domain–mediated interactions influence Hippo pathway activity.

Chile’s Social Unrest: Why It’s Time to Get Serious about a ‘Just’ Transition

4 November 2019

President Sebastián Piñera’s decision to cancel the COP25 climate negotiations, which Chile was due to host in early December, shows the importance of ensuring the transition to a sustainable world is just.

2019-11-04-Chile-Protests.jpg

One year ago, during the last annual Conference of Parties (COP) held in Katowice, the Polish government launched a Solidarity and Just Transition Declaration, signed by 56 governments including the UK, making the case for why the green transition must be just.

Three years earlier in 2015, the landmark Paris Agreement also included provisions for a just transition where it stated that the decarbonization process should be ‘Taking into account the imperatives of a just transition of the workforce and the creation of decent work and quality jobs in accordance with nationally defined development priorities’. In practice, however, the concept of a just transition has not yet been implemented and has not been sufficiently considered by governments or corporations around the world.

The social unrest that has erupted in Chile’s capital Santiago over the past month, which has forced the Chilean government to ask to move this year’s COP to Madrid, is a case in point. This discontent clearly shows that climate action cannot be separated from social justice concerns. There has not been a real commitment by governments to ensure a just transition based on social dialogue from the local to the national level. This was seen in France with the gilets jaunes protests in November 2018 – one month after President Emmanuel Macron ended the so-called ‘fortune tax’ and instead introduced taxes on diesel fuel as part of an effort to transition to green energy – and the current situation in Chile has some striking parallels. 

Sustainability transitions are a complex web of political choices and investment decisions which affect countries and societies in many different ways. Questions of social justice are everywhere, but in most cases, poorly understood by decision-makers. For example, although poverty has been reduced significantly over the last decade, Chile has one of the worst rates of inequality in Latin America and the highest Gini index in the OECD. The decisions taken in 2017 to power Metro de Santiago with solar photovoltaics and wind energy are commendable from a climate perspective, however, it led to students and young people protesting against rises in subway fares in October 2019.

They were joined by Chileans who are frustrated with rising living costs and by workers and trade unions struggling with low wages. As reported by the Chilean Human Rights Commission (INDH), so far more than 4,200 people have been arrested and more than 1,300 injured and hospitalized.

Climate negotiations beyond technicalities

This time there is also another important dimension to the protests: social unrest as a reaction to worsening inequality has the potential to derail multilateral cooperation on climate change and other global issues. Since tackling climate change is a race against the clock, the world faces the challenge of addressing both urgency and equity. The world cannot afford delays and needs to move fast but decision-makers need to take time for deliberation and civic participation to avoid rapid and ill-conceived transitions which eventually meet public resistance.

Many technical experts and negotiators, who often unintentionally divorce climate policy and technical discussions about emission reductions from social justice concerns, have been caught by surprise by the cancellation of the negotiations. For this year’s COP, one important focus of the official negotiations are the so-called 'Article 6 Rules' – the accounting mechanisms and modalities for a new form of international interaction on carbon markets and off-setting to ensure carbon markets can support countries in enhancing the ambitions of their stated climate action, known as Nationally Determined Contributions (NDCs). 

What is becoming much more obvious now is that just transitions are at least equally important for achieving NDCs and other long-term mitigation strategies.

In order to meet the 1.5 degree target, stated by the Intergovernmental Panel on Climate Change (IPCC), the world will have to invest an average of around $3 trillion a year over the next three decades in transforming its energy supply systems. But how can we ensure that these investments benefit low-income communities? Will they further increase everyday living costs? The climate finance related discussions focussing on commercially-oriented investments for low-carbon energy systems in most cases only consider the aspect of affordability, but not the other important principles of alternative ‘just’ energy finance, such as good governance, due process, intra-generational equity, spatial equity and financial resilience. Investments to support just transitions need to ensure investments, not only for large energy infrastructure, but also in the jobs, skills and work vital to both adaptation and mitigation.

Just transitions for a circular economy

The just transition concept is also the entry point to broader discussions about inclusive economic transformations, questioning the dominant paradigm of consumerism and ending the wasteful use of critical resources. The current linear economic model of take-make-throw away – in Chile epitomized by the linear extractive model of the mining sector that has contributed to widening inequality – the linear extractive model is not only destructive on the natural environment but also destructive for social cohesion.

In Chile, the commodity boom in copper production – the country accounts for about 30 per cent of the world’s output – and more recently lithium – which is used in batteries for mobile phones, laptops and electric cars – have generated enormous prosperity in Chile. But the wealth has been unequally distributed and has not been used to lay the foundation for raising the overall level of incomes.

A socially embedded and inclusive circular economy can, therefore, be a way forward from the current situation the Latin American country finds itself in. The circular economy was intended to feature prominently during the 25th COP and Chile’s policies – from the Ministry of Environment and Chile's Production Development Corporation (CORFO) – have played an important role in supporting the development of a circular economy, launching in 2018, the first public circular economy programme in Latin America

The government’s support for start-up companies and entrepreneurs to develop inclusive circular economy business models is the right approach to addressing the issues of waste, employment, services for low-income communities and local economic development. These are solutions that need to be scaled up having the potential to reduce Chile’s economic reliance on the dominant extractive model.

As a global community, it is necessary to address the environmental and social objectives equally as not addressing social objectives will become an obstacle in achieving climate mitigation and solving other environmental issues. 

The Chilean protests are a wake-up call and present an opportunity for the global climate change community – which includes governments – to ensure just transitions are implemented in practice.

Climate Action in 2020: Time to Focus on Forests

14 January 2020

Alison Hoare

Senior Research Fellow, Energy, Environment and Resources Programme
More ambitious policies to reduce deforestation are key to effective climate policy, but to succeed, they require three big changes in approach.

2020-01-14-ReforestBrazil.jpg

December’s UN climate talks held in Madrid were aptly titled ‘Time for Action’. While little progress was made at the conference in establishing an international framework that would help to instigate this, there is still much scope for action in 2020. The need for this has become all too apparent as the impacts of climate change are increasingly seen around the world.

One of the key areas where progress can be made in 2020 is in increasing the ambition of nationally determined contributions (NDCs), these being governments’ plans to take action in response to climate change. To date, 184 countries have submitted NDCs, yet the commitments that have been made fall far short of what is needed to avert catastrophic climate change.

In 2020, however, many countries will be revising their NDCs, presenting an important opportunity to shift momentum; to date 79 countries have announced that they will be enhancing the ambition of their NDCs.

The forest sector is one area where more ambitious targets are likely to be set, and indeed, at the Climate Action Summit in September 2019, more than 20 countries made new commitments for the conservation, reforestation and restoration of their forests.

This will be essential. As is well documented, reducing deforestation is critical to reducing carbon emissions, while healthy and diverse forests are vital for adapting and increasing resilience to climate change.

However, while it is important that ambitious targets are set, this is relatively easy; the bigger challenge lies in ensuring that these are achievable.

This is all too apparent from experience thus far. In 2014, the New York Declaration on Forests set the goal to halve forest loss by 2020, and to end it by 2030. In addition, it included the goal to restore 150 million hectares of degraded landscapes and forestlands by 2020, and a further 200 million hectares by 2030.

The declaration has been endorsed by over 50 countries, as well as business and civil society organizations, yet the 2020 goals are far from being reached – in the six years since the declaration was launched, it has been found that forest loss increased rather than declined, and only about 27 million hectares of land have been restored.

What then is needed to ensure that the commitments being made by governments in their NDCs will actually be met? Three big changes are required.

Firstly, a shift in perspective is needed in many countries to a more forest-sensitive approach to development, one that gives adequate recognition to the full range of values provided by forests, rather than primarily focusing on their role as a global carbon sink. These include their importance for local and national economies, for livelihoods and the well-being of forest-dependent peoples, and for biodiversity and the regulation of local climate and water systems.

The focus on nature-based solutions at the international level offers potential to support this shift. However, it is critical that these are not seen as ‘niche’ approaches, and that countries identify what nature-based solutions mean for them, and how forests and tree-rich landscapes can best be integrated into their development strategies.

Fundamental to achieving this will be further improvements in governance, and this is the second change that is required. Legal and institutional reforms are needed in many countries as well as significant investments in human and technical resources. This will enable processes to be strengthened, or put in place, so that equitable strategies can be developed and implemented – strategies that reflect a balance of the needs and priorities of the full range of stakeholders, including local and global, rural and urban, women and men, young and old.

Financing will of course be critical for this, and the least developed countries in particular will be hindered in the actions they can take without additional finance. This is the third area of change that is needed, and it is to be hoped that the international community will make better progress on this in 2020. Forest and land-use options are often described as a cost-effective means of tackling climate change, as is noted in the Santiago Call for Action on Forests for example.

This is not to say that these will be easy or cheap – as Chatham House has documented, experience of forest governance reform has shown that it takes significant funding and time to bring about deep-rooted change. However, the huge potential benefits that can result, for the citizens of forest-rich countries as well as for the planet, mean that forests and sustainable land-use are a good investment.

The Review on Antimicrobial Resistance, chaired by Jim O’Neill, was commissioned by former UK prime minister, David Cameron, in July 2014. Supported by the UK government and the Wellcome Trust, the final report of the review was published in May 2016 and has had a global impact in terms of motivating political leaders and decision-makers to take more seriously the threat posed by antimicrobial resistance.

Yet there is now a perception that the political momentum to address the issue is waning and needs to be reinvigorated.

In a further report produced by Chatham House, the progress of the recommendations of the review is assessed and the key ways to move forward are identified.

Panellists at this event, where highlights of the report are presented, provide their assessment of the progress so far and discuss priorities for future action.

The report was funded by Wellcome.

  • The 2016 Review on Antimicrobial Resistance has had a global impact: as an advocacy tool, in raising the profile of antimicrobial resistance (AMR) on the international agenda, and in helping to stimulate a number of new initiatives, in particular relating to the funding of early-stage research.
  • However, there has been very little progress on the review’s central and most expensive recommendations for transforming research and development incentives for antibiotics, vaccines and diagnostics.
  • There have been significant advances in reducing antibiotic use in agriculture, particularly in high-income countries, but there is a long way to go in low- and middle-income countries (LMICs).
  • There has been greater investment in awareness raising but questions remain about its impact and effectiveness in changing behaviour.
  • Proposals to restrict over-the-counter sales of antibiotics, as recommended by the Review, have foundered in the face of poor living conditions and access to healthcare in LMICs.
  • A major reason for the use of antibiotics in LMICs is the prevalence of unhygienic conditions in the community and in healthcare facilities, which contribute to infection and limit the impact of messages about awareness and infection prevention and control.
  • Providing quality healthcare to all and moving towards universal health coverage in LMICs will be crucial in addressing the problems of both adequate access to antibiotics and in restricting over-the-counter sales.
  • A greater emphasis on investments in water, sanitation and housing will be central to reducing reliance on antibiotics in LMICs in the longer term. This agenda should inform the operations of governments and funding agencies such as the International Monetary Fund (IMF) and the World Bank.
  • Investments have been made in improving surveillance of antibiotic use and resistance, particularly for humans, but more effort is required to create surveillance systems that provide data sufficiently accurate to influence policy and action. This applies also to antibiotics and resistant genes circulating in the environment.
  • The emerging innovations in the global governance of AMR need to lead to action rather than more words.

Coronavirus: Public Health Emergency or Pandemic – Does Timing Matter?

1 May 2020

Dr Charles Clift

Senior Consulting Fellow, Global Health Programme
The World Health Organization (WHO) has been criticized for delaying its announcements of a public health emergency and a pandemic for COVID-19. But could earlier action have influenced the course of events?

2020-05-01-Tedros-WHO-COVID

The World Health Organization (WHO) declared the spread of COVID-19 to be a Public Health Emergency of International Concern (PHEIC) on January 30 this year and then characterized it as a pandemic on March 11.

Declaring a PHEIC is the highest level of alert that WHO is obliged to declare, and is meant to send a powerful signal to countries of the need for urgent action to combat the spread of the disease, mobilize resources to help low- and middle-income countries in this effort and fund research and development on needed treatments, vaccines and diagnostics. It also obligates countries to share information with WHO.

Once the PHEIC was declared, the virus continued to spread globally, and WHO began to be asked why it had not yet declared the disease a pandemic. But there is no widely accepted definition of a pandemic, generally it is just considered an epidemic which affects many countries globally.

Potentially more deadly

The term has hitherto been applied almost exclusively to new forms of flu, such as H1N1 in 2009 or Spanish flu in 1918, where the lack of population immunity and absence of a vaccine or effective treatments makes the outbreak potentially much more deadly than seasonal flu (which, although global, is not considered a pandemic).

For COVID-19, WHO seemed reluctant to declare a pandemic despite the evidence of global spread. Partly this was because of its influenza origins — WHO’s emergency programme executive director said on March 9 that ‘if this was influenza, we would have called a pandemic ages ago’.

He also expressed concern that the word traditionally meant moving — once there was widespread transmission — from trying to contain the disease by testing, isolating the sick and tracing and quarantining their contacts, to a mitigation approach, implying ‘the disease will spread uncontrolled’.

WHO’s worry was that the world’s reaction to the word pandemic might be there was now nothing to be done to stop its spread, and so countries would effectively give up trying. WHO wanted to send the message that, unlike flu, it could still be pushed back and the spread slowed down.

In announcing the pandemic two days later, WHO’s director-general Dr Tedros Adhanom Ghebreyesus reemphasised this point: ‘We cannot say this loudly enough, or clearly enough, or often enough: all countries can still change the course of this pandemic’ and that WHO was deeply concerned ‘by the alarming levels of inaction’.

The evidence suggests that the correct message did in fact get through. On March 13, US president Donald Trump declared a national emergency, referring in passing to WHO’s announcement. On March 12, the UK launched its own strategy to combat the disease. And in the week following WHO’s announcements, at least 16 other countries announced lockdowns of varying rigour including Austria, Belgium, Canada, Czech Republic, Denmark, Finland, France, Germany, Hungary, Netherlands, Norway, Poland, Portugal, Serbia, Spain and Switzerland. Italy and Greece had both already instituted lockdowns prior to the WHO pandemic announcement.

It is not possible to say for sure that WHO’s announcement precipitated these measures because, by then, the evidence of the rapid spread was all around for governments to see. It may be that Italy’s dramatic nationwide lockdown on March 9 reverberated around European capitals and elsewhere.

But it is difficult to believe the announcement did not have an effect in stimulating government actions, as was intended by Dr Tedros. Considering the speed with which the virus was spreading from late February, might an earlier pandemic announcement by WHO have stimulated earlier aggressive actions by governments?

Declaring a global health emergency — when appropriate — is a key part of WHO’s role in administering the International Health Regulations (IHR). Significantly, negotiations on revisions to the IHR, which had been ongoing in a desultory fashion in WHO since 1995, were accelerated by the experience of the first serious coronavirus outbreak — SARS — in 2002-2003, leading to their final agreement in 2005.

Under the IHR, WHO’s director-general decides whether to declare an emergency based on a set of criteria and on the advice of an emergency committee. IHR defines an emergency as an ‘extraordinary event that constitutes a public health risk through the international spread of disease and potentially requires a coordinated international response’.

In the case of COVID-19, the committee first met on January 22-23 but were unable to reach consensus on a declaration. Following the director-general’s trip to meet President Xi Jinping in Beijing, the committee reconvened on January 30 and this time advised declaring a PHEIC.

But admittedly, public recognition of what a PHEIC means is extremely low. Only six have ever been declared, with the first being the H1N1 flu outbreak which fizzled out quickly, despite possibly causing 280,000 deaths globally. During the H1N1 outbreak, WHO declared a PHEIC in April 2009 and then a pandemic in June, only to rescind both in August as the outbreak was judged to have transitioned to behave like a seasonal flu.

WHO was criticized afterwards for prematurely declaring a PHEIC and overreacting. This then may have impacted the delay in declaring the Ebola outbreak in West Africa as a PHEIC in 2014, long after it became a major crisis. WHO’s former legal counsel has suggested the PHEIC — and other aspects of the IHR framework — may not be effective in stimulating appropriate actions by governments and needs to be reconsidered.

When the time is right to evaluate lessons about the response, it might be appropriate to consider the relative effectiveness of the PHEIC and pandemic announcements and their optimal timing in stimulating appropriate action by governments. The effectiveness of lockdowns in reducing the overall death toll also needs investigation.

Thant Myint-U, Conservationist; Author, The Hidden History of Burma: Race, Capitalism, and the Crisis of Democracy in the 21st Century
Chair: Champa Patel, Head of Asia-Pacific Programme, Chatham House

Just a few years ago the West was celebrating what appeared to be the conclusion of a quarter-century long contest between Myanmar’s democrats and a military dictatorship. Today, the country stands charged with genocide at the International Court of Justice, with Aung San Suu Kyi leading the defence. Is Myanmar a democratic transition gone awry? Or something else entirely?  

The speaker will argue that Myanmar is not the simple morality tale often portrayed. It has instead become the stage for some of the world’s most pressing challenges such as climate change, explosive inequality and rising populism, the impact of social media; and the rise of China as the next global superpower.

In this context, are 20th century democratic institutions and free-market reforms the correct remedy for a country plagued by the legacies of colonialism, decades of civil war, tyranny and a predatory economic system? The speaker will offer a prognosis for Myanmar’s future, assessing the question of whether it will become Asia’s next failed state.

This event will be held off the record.

Pulling Out (from) All the Stops - Visiting all of NY's subway stops in record time

With 468 stops served by 26 lines, the New York subway system can make visitors feel lucky when they successfully negotiate one planned trip in a day. Yet these two New Yorkers, Chris Solarz and Matt Ferrisi, took on the task of breaking a world record by visiting every stop in the system in less than 24 hours. They used mathematics, especially graph theory, to narrow down the possible routes to a manageable number and subdivided the problem to find the best routes in smaller groups of stations. Then they paired their mathematical work with practice runs and crucial observations (the next-to-last car stops closest to the stairs) to shatter the world record by more than two hours!

Although Chris and Matt.s success may not have huge ramifications in other fields, their work does have a lot in common with how people do modern mathematics research

* They worked together, frequently using computers and often asking experts for advice;
* They devoted considerable time and effort to meet their goal; and
* They continually refined their algorithm until arriving at a solution that was nearly optimal.
Finally, they also experienced the same feeling that researchers do that despite all the hours and intense preparation, the project .felt more like fun than work.
