The branches on trees around Kenya's northern town of Lodwar have been stripped bare of leaves, bending downwards under the weight of voracious young locusts.

Numbers of locusts exploded in East Africa and the Red Sea region in late 2019, exacerbated by atypical weather patterns amplified by climate change. Swarms of insects flew west from Yemen, and this year reached Kenya, Somalia and Ethiopia.

The new generation has hatched in Turkana, Kenya's poorest region. The young locusts are eating everything in sight, and when their wings mature the swarms will be able to travel up to 130 kilometers (80 miles) in a day. The hatchings have occurred as crops are planted in a region where 20 million people struggle for food.

"The locusts have come to destabilize an already bad situation," said Daniel Kirura, head of the United Nations Food and Agriculture Organization in Turkana.

Kirura fears the swarms will spread quickly and said teams are working frantically to spray them with insecticide before they become airborne.

"Within one week they may mature to swarms that may fly away," Kirura said. "Our wish is to control them before they leave Turkana."

Turkana is a vast, dry scrubland in northwest Kenya that borders Uganda, South Sudan and Ethiopia. Residents say the insects are devastating farmland and grazing areas.
