The desert locust, the most destructive migratory pest in the world, is highly mobile and feeds on large quantities of any kind of green vegetation, including crops, pasture, and fodder with great potential to cause deterioration in the food security situation across the East Africa region. Ethiopia experienced two invasions of locust in 2020. The first invasion, which spread from Yemen to Ethiopia, Kenya, Somalia, Uganda, Sudan, and Tanzania, took place from January to May. This first invasion of desert locust is reported to have invaded 180-240 Woredas and laid to waste over 200,000 hectares of land in Ethiopia alone, primarily in crop land in eastern and southern Ethiopia. The second invasion of locust in Ethiopia, which started in late September and peaked in October-November is the worst locust invasion and feared to be 20 times more severe that than the first invasion and it has destroyed crops, grazing lands and trees. The impacts of locust invasions are exacerbated by COVID-19 restrictions, war, and flooding which are expected to substantially reduce Ethiopia’s economic growth. Poverty levels are expected to rise and over 2 million people estimated to fall into poverty while the scale of Productive Safety Net Programme is expected to rise from 9 million to as high as 15 million.1 1 One UN Assessment: Socio-Economic Impacts of COVID 19 in Ethiopia (2020).
