If strong earthquakes, volcanic eruptions and virus outbreaks were not enough to start 2020, we now have a locust swarm of biblical proportions ongoing in Eastern Africa.
Over a billion of locusts are swarming the countries of eastern Africa. The huge locust swarm first moved through Ethiopia and Somalia, where the people faced the worst locust outbreak in at least 25 years. The desert locusts now also plague Kenya, in even larger numbers, creating the largest locust swarm in at least 70 years!

These locusts have endless appetite. They destroy crops, farmlands, and everything green, and so reduce the food supply in a region that is already facing severe hunger problems.

One massive swarm of locusts measured 60 kilometers by 40 kilometers! A typical large swarm can contain around 150 million locusts per square kilometer (150 per m2), which means this massive swarm likely contained several hundred billion of locusts. A locust swarm moves in very high numbers and at fairly high speeds. They can cover up to 150km distance in just one day. In Kenya, The locusts have overrun over 70.000 hectares (173.000 acres) of land. Farmers and the local police are fighting the swarm with smoke and tear gas, but the effects are limited, as the swarm is very large.
East Africa locust invasion, worst in 70 years. In just one day, a small swarm can eat crops enough to feed 35,000 people.
One swarm measured 60km long by 40km wide. About 70,000ha in Kenya hit. UN says $70m needed to step up aerial spraying. The bugs travel 150km/day.

A locust can usually eat as much food as its own body weight. One square kilometer swarm can consume enough food in one day to feed over 35.000 people. Now a potentially threatening situation is developing along both sides of the Red Sea, where ongoing breeding is causing locust numbers to increase on the coasts of Egypt, Sudan, Eritrea, Saudi Arabia, and Yemen. There is a risk that some swarms could appear in northeast Uganda, southeast South Sudan, and southwest Ethiopia. Uganda has not seen such an outbreak for atleast 60 years. This situation can also cause severe problems for South Sudan, where there is a food crisis already ongoing, as the country emerges from civil war.

Why is the locust swarm this year so unusually large? A lot of it has to do with a strong positive Indian Ocean dipole (IOD). A positive IOD causes warmer waters and temperatures along the east African coast, and more humid conditions, which are a perfect breeding ground for large locust swarms.
Very large Locust swarm spread over 1km spotted last night in Raisinghnagar, Rajasthan next to Punjab.
On my farm in maujgarh, have Locusts in small numbers on Kinnow trees.
Let's not lull ourselves reading newspapers, the threat has not receded, it's a clear and present danger pic.twitter.com/zjPO6rE0kz
