Earthquakes, floods and droughts are growing more frequent and could displace as many as one billion people by 2050. Existing studies disagree about when such environmental shocks lead to political violence.

What they work on

  1. Build and release a global dataset of government policy responses to natural disasters for all countries from 1900 to 2020.
  2. Test statistically whether restricting movement of disaster-affected populations, or restricting third-party aid efforts, increases the likelihood of political violence after disasters.
  3. Test whether unequal aid to politically favored regions, decentralized disaster management, and small pre-disaster remittance flows raise post-disaster conflict risk.
  4. Conduct twenty-four country case studies of disaster responses to trace how specific policy choices connect disasters to political violence.

More about the research

This project argues that much of the answer lies in what governments do after disaster strikes, and it sets out to measure those policy choices across more than a century of cases.

Why it matters

Poorly handled disaster responses may turn natural hazards into political violence. By identifying which government policies raise or lower that risk, the work could inform how affected states respond, how donors design aid, and how the U.S. government prepares to support disaster relief abroad, a sizable part of its foreign assistance. The new open dataset would also be reusable by other researchers and analysts.
