I am a postdoctoral fellow at Princeton University and International Crisis Group.

My research interests include political and development economics, with focus on the implications of climate change and infrastructure for conflict.

Previously based at the Centre for Economic Performance at the London School of Economics. I received my Ph.D. in Economics from the University of Lausanne, M.Sc. in Economic Policy from the University College London and B.A. in Economics from the University of Zurich.

Where science meets policy.

At Crisis Group, I lead the Climate Change and Conflict work-stream, brief heads of state, foreign ministries and inter-governmental organizations to shape their thinking on climate security topics.

At Princeton University's Empirical Studies of Conflict Project, I participate in the “Measuring Commercial Influence” project, funded by the DoD’s Minerva Research Initiative.

How Climate Change Fuels Deadly Conflict

This explainer details our understanding of the links between climate and conflict. The relationship of climate change to deadly violence is a complex one – which is precisely why we believe the Council should engage, not avoid, the subject. The resolution's main provisions include systematic UN analysis of climate risks to peace and security, more attention to climate change by peacekeeping and diplomatic missions, the sharing of data and building platforms to provide “real-time” information. These are unmitigated goods, regardless of how one views the exact nature of the climate-conflict nexus.

Getting Conflict into the Global Climate Conversation

Climate change and conflict do not exist in isolation from each other. The countries most exposed to climate change are disproportionately affected by conflict, and many of the countries suffering from both often suffer as well from poor governance – all of which stand in the way of adaptation and mitigation measures. Half of the most climate-fragile countries in the world also face conflict and crisis today, according to Crisis Group’s calculations.

Can the UNSC Agree on a Climate Security Resolution?

UN Security Council members are discussing a draft resolution on climate security tabled by Ireland and Niger at the end of September. If it passes, it will be the first resolution of its kind, although the Council has held sessions on climate change and its implications for peace and security since 2007. These discussions, which were sporadic at first, have become much more frequent in the last five years. But aside from one statement (which lacks the stature of a resolution) in 2011, the Council has never formally put its concerns about climate change on paper.

The Climate Factor in Nigeria’s Farmer-Herder Violence

Africa is especially vulnerable to climate change, as millions are already experiencing record heat, extreme precipitation and rising sea levels. Increasingly, the security implications of changing weather patterns are visible in deadly land resource disputes between farmers and herders across the continent – including in the continent’s most populous country, Nigeria.
