ADDIS ABABA, Ethiopia -- The most serious outbreak of locusts in 25 years is spreading across East Africa and posing an unprecedented threat to food security in some of the world’s most vulnerable countries, authorities say. Unusual climate conditions are partly to blame.
“A typical desert locust swarm can contain up to 150 million locusts per square kilometer,” it said. “Swarms migrate with the wind and can cover 100 to 150 kilometers in a day. An average swarm can destroy as much food crops in a day as is sufficient to feed 2,500 people.”
The outbreak is making the region's bad food security situation worse, the United Nations’ Food and Agriculture Organization has warned. Hundreds of thousands of acres of crops have been destroyed.
The further increase in locust swarms could last until June as favorable breeding conditions continue, IGAD said, helped along by unusually heavy flooding in parts of the region in recent weeks.
Major locust outbreaks can be devastating. A major one between 2003 and 2005 cost more than $500 million to control across 20 countries in northern Africa, the FAO has said, with more than $2.5 billion in harvest losses.
To help prevent and control outbreaks, authorities analyze satellite images, stockpile pesticides and conduct aerial spraying. In Ethiopia, officials said they have deployed four small planes to help fight the invasion.
But one approach backfired in Kenya in recent days when the agriculture minister asked people to post photos on social media of suspected locusts, or “nzige” in Swahili.
A mocking series of images of warthogs, cats, lizards and other beasts followed, with pleas for help in identifying them, and the appeal was ended.
