East Africa: Desert Locust Resurgence Worries in Horn of Africa, Reports UN Agency

The Desert Locust crisis, which struck the greater Horn of Africa region earlier this year, could re-escalate as recent strong winds carried small mature yellow swarmlets from southern Somalia into eastern and northeastern Kenya, the UN Food and Agriculture Organization (FAO) has said.

Although some of the swarmlets that reached Kenya may have already laid eggs before their arrival, there remains a risk of further egg-laying in sandy areas that saw recent rainfalls, according to FAO.

“In this case, hatching and hopper band formation can be expected in early December,” said the agency.

Breeding also continues in central Somalia and eastern Ethiopia where bands of hoppers – non-flying, nymphal stage locust – are present, and a new generation of immature swarms could start forming by the end of November.

Swarm formation is expected to continue throughout December due to widespread hatching and band formation that occurred mid-November. From the second week of December, several waves of numerous swarms can be expected to move south in Somalia and Ethiopia, reaching northern Kenya, FAO added.

A resurgence of the swarms could aggravate food security in the region, where almost 25 million people are already suffering from severe acute food insecurity. Desert Locusts are considered the most destructive migratory pest in the world, devouring large areas of crops and grasses meant for people and livestock.

Scaling up response

FAO is supporting authorities in Somalia to scale up anti-locust measures, focusing on areas at high risk.

“Survey and control operations, by ground and by air, have been scaled-up and are on-going,” said Etienne Peterschmitt, FAO Representative in Somalia.
