Gargantuan tribes of desert locusts have been terrifying the residents of Yemen and Saudi Arabia and laying waste to countries in the Horn of Africa. UN’s Food and Agriculture Organization (FAO) calls the outbreak worst in 25 years for the Eastern Africa and worst Kenia in particular faces in 70 years.
After multiplying in the Horn of Africa, the swarms may migrate to Hindustan, where they may deliver a twin strike together with freshly hatched locust from southern Iran, FAO’s Senior Locust Forecasting Officer Keith Cressman told IANS news agency on 10th February (Monday).
The worst-case scenario would require an early breeding season for locusts in Iran, which may be caused by warm weather and plentiful rains. The conditions in the Horn of Africa are currently favorable for fast replication of the pests, which is causing the ongoing infestation in the first place. If they remain as good for the insects, migration to India and Pakistan, which has not happened for quite some time, is likely this year, the official said.“There is a potential risk that the swarms can move from the Horn of Africa, starting in about mid-May until about some time in July to meet those monsoon rains that arrive in Rajasthan in India and Cholistan-Tharparkar in Pakistan,” he said.
[It] is due to the large concentration of locusts that are currently present in Kenya, Somalia and Ethiopia, and the possibility for them to increase further in number in the next six months between now and June so they can increase up to 400 times than we have now.
Iranian locusts hit Pakistan and India the previous year. Cressman said he hoped the two nations are better prepared than countries like Somalia or Ethiopia to deal with the swarms. African nations lack security and funding to control and contain the plague that may soon seriously affect South Sudan, Uganda and Tanzania, according to FAO. The region is already suffering from food insecurity, so the crisis may lead to serious starvation.
Desert locus is among the most dangerous pests. A 2-gram adult insect is capable of eating its weight worth of food in a day while a swarm usually consists of several tens of millions. They can also fly as far as 150 km in a day after eating crops in a particular area. No wonder a locust infestation is mentioned as one of the Biblical plagues in Exodus.
