Finalist, Locust Invasion in East Africa by Luis Tato

Desert locusts are the most destructive migratory pests in the world. Thriving in moist conditions in semi-arid to arid environments, billions of locusts have been feeding throughout East Africa, devouring everything in their path, and posing a huge threat to the food supply and livelihoods of millions of people. Farmers stand by as armies of ravenous insects eat their crops; meanwhile, herders watch the rangelands stripped bare before their livestock can get to them. Extreme rainfall events and severe weather anomalies have created ideal conditions for locust breeding and feeding. Swarms of desert locusts from the Arabian Peninsula began rampaging across East Africa in early 2020, devouring crop and vegetation where they landed. The crisis reached historic proportions, with 10 countries in the Greater Horn of Africa and Yemen experiencing infestations. Some areas of East Africa, such as Kenya, had not seen such severe desert locust outbreaks in more than 70 years. Covid-19 restrictions have significantly slowed efforts to fight the infestation, as crossing borders has become more difficult, creating delays and disrupting the supply chains of pesticides and products needed to prevent these pests from wiping out vegetation across the region and exposing millions of people to high levels of food insecurity.
