Climate change and locust outbreak in East Africa
From the end of 2019 to early 2020, a desert locust (Schistocerca gregaria) outbreak across several East African countries posed a serious risk to food security and livelihoods. A second wave is currently active and threatening the region’s agropastoral areas. Although desert locusts have been here since biblical times, recent intense outbreaks can be linked to anthropogenic climate change and the increased frequency of extreme weather events1,2,3. Current locust plagues are further exasperated by local economic and political limitations, which facilitate locust spread and place particular pressure on already vulnerable communities.
