By early to mid-March 2020, 21 counties in Kenya had been harmed since desert locusts invaded northeastern Kenya on December 28, 2019. 

Currently the Desert Locusts are mainly located in the winter breeding areas of the Red Sea and the Gulf of Aden coast and Pakistan, and the winter-spring breeding areas of Ethiopia and Kenya in southern Horn of Africa.

The Desert Locust has ravaged the Horn of Africa and Southwest Asia, posing serious threats on agricultural production and food security of the inflicted regions.
