Economist (PhD) | Conflict, climate and natural resources in fragile states
Independent researcher and consultant
Associate Researcher, CERDI
2025-2026 Fellow, Civil War Paths (University of York)
I am a development economist studying the structural causes of internal conflict and how political, economic and environmental processes interact to shape conflict and insecurity in fragile contexts. I combine applied econometrics and geospatial data, including satellite imagery and geolocated event data, with qualitative research to investigate these relationships, drawing on meta-analysis, interviews and scenario analysis. My work spans conflict economics and systemic risk analysis, from academic research to applied policy work. I work fluently in French and English.
This site follows where my research stands, region by region: close-ups on Chad and the Sahel, Central Africa, the Middle East and Papua New Guinea, and a wide angle on shocks, arms and finance.
Questions I work on
What drives internal conflict, and what do our conflict data actually measure? PhD thesis; Revue française d’économie (2019); Journal of Peace Research (2025). Wide angle →
How do access to land and its governance shape both conflict and resilience in drylands? Cross-border transhumance between Niger and Nigeria; Sudanese refugee women in eastern Chad; the JASS programme in Mali and Niger. Chad and the Sahel →
How do conflict, displacement and environmental degradation compound each other in protracted crises? Eastern DRC, Yemen, Syria, Papua New Guinea. Central Africa → · Middle East → · Pacific →
Who carries climate risk, and who gets climate finance? Chad’s climate-finance readiness; risk sharing in World Bank projects; Japan’s bilateral climate finance. Wide angle →

Recent publications
Research agenda
My current research asks how land and natural resources shape both conflict and peace in drylands and fragile settings.
- Land degradation, peace and security. Why relatively safe areas hosting displaced people come under heavy environmental pressure and become political bargaining spaces, and what inclusive community governance of land can achieve there.
- Who carries climate risk? Domestic contractors, climate shocks and project performance in World Bank procurement (with Paul Vernus, CERDI).
- Gender and climate finance. What climate-finance tags reveal, and hide, about gender integration: lessons from Japan (with E. Tan and T. Kamninga, ODI Global).
- From the PhD. Grassland scarcity and herder–farmer conflict across the Niger–Nigeria border; the politicisation of religion and the timing of political conflict.
