Somalia has declared a national emergency as desert locusts destroy vegetation. An average swarm containing 40 million insects can travel 150 km in 24 hours, devouring enough food to feed 34 million people in that time. The UN said it is a race against time to tackle this invasion amidst ongoing humanitarian challenges. A spokesman said, ‘We do have a chance to nip this problem in the bud, but that’s not what we’re doing at the moment.’ Kenya’s food security is threatened, particularly communities keeping livestock on endangered pastures. Swarms crossed into Uganda on 9 February, and Tanzania and South Sudan are now on the UN’s ‘watch list’. Also, insufficient rain means that over two million Somalis will need emergency food aid this year after the worst harvest in 25 years. 300,000 were displaced in eight months; many have headed for the capital, Mogadishu. Six million Kenyans are food-insecure, while seven million Zimbabweans need aid after successive droughts and an inflation rate of 300%. Urban families are feeling the pinch of soaring prices. See
