The Sound of Their Wings: Desert Locusts and Conflicts in Africa
(2018)- Abstract
- Do negative income shocks increase conflict risk? I study the relationship between desert locust infestations and conflict in 26 African countries. Combining geolocalized data on locust swarms and bands with information on conflict events, I construct two panel datasets at spatial resolutions 0.5◦ × 0.5◦ and 0.1◦ × 0.1◦, covering the years 1997–2017. I find a negative relationship between locust infestations and conflict after accounting for cell and country-year fixed effects and month-specific polynomials of local precipitation and temperature. However, these results may reflect under-reporting by locust survey teams in areas and years of conflict. An IV strategy, drawing on insights about the weather conditions suitable for swarm and...
