The Associated Press, The Denver Post eEdition, July 6, 2020 NAIROBI, KENYA»The crunch of young locusts comes with nearly every step. The worst outbreak of the voracious insects in Kenya in 70 years is far from over, and their newest generation is now finding its wings for proper flight. The livelihoods of millions of already vulnerable people in East Africa are at stake, and people like Boris Polo are working to limit the damage. The logistician with a helicopter firm is on contract with the United Nations Food and Agricultural Organization, helping to find and mark locust swarms for the targeted pesticide spraying that has been called the only effective control.“It sounds grim because there’s no way you’re gonna kill all of them because the areas are so vast,” he told The Associated Press from the field in northwestern Kenya on Thursday. “But the key of the project is to minimize” the damage, and the work is definitely having an effect, he said.
For months, a large part of East Africa has been caught in a cycle with no end in sight as millions of locusts became billions, nibbling away the leaves of both crops and the brush that sustains the livestock so important to many families. “The risk of significant impact to both crops and rangelands is very high,” the regional IGAD Climate Prediction & Applications Center said Wednesday in a statement. For now, the young yellow locusts cover the ground and tree trunks like a twitching carpet, sometimes drifting over the dust like giant grains of sand.
In the past week and a half, Polo said, the locusts have transformed from hoppers to more mature flying swarms that in the next couple of weeks will take to long-distance flight, creating the vast swarms that can largely blot out the horizon. A single swarm can be the size of a large city. Once airborne, the locusts will be harder to contain, flying up to 124 miles a day.
“They follow prevailing winds,” Polo said. “So they’ll start entering Sudan, Ethiopia and eventually come around toward Somalia.” By then, the winds will have shifted and whatever swarms are left will come back into Kenya.” The next generation could be up to 20 times the size of the previous one. The trouble is, only Kenya and Ethiopia are doing the pesticide control work. “In places like Sudan, South Sudan, especially Somalia, there’s no way, people can’t go there because of the issues those countries are having,” Polo said. — The Associated Press
