From the Biblical plagues of Egypt to the resurgence of locusts in 2020, these creatures are nothing to scoff at. When roused, a swarm can cover over a hundred kilometers per day, with each little locust eating its own bodyweight in leaves shoots, fruits, flowers, seeds, stems and barks. Needless to say, the wasteland they leave behind is quite bleak. If the swarm grows enough to affect two or more regions at once, it is upgraded to a plague which can cover up to 512,000km2 (largest swarm recorded, US Midwest, 1875).

(2019 -2020) For months, locust plagues stretching tens of kilometres in length and breadth have blighted central and eastern Africa, the Middle East and parts of Asia, including Pakistan and India.
The swarms first arrived in the Horn of Africa at the end of summer 2019. They had moved in from the Arabian desert, where good breeding conditions in the months prior had allowed them to multiply by an astonishing 8,000-fold, according to the UN’s Food and Agricultural Organization (FAO). In the autumn months of 2019, the insects spread further inland from Somalia and Ethiopia into countries including Kenya and Uganda. In Kenya, the FAO’s locust watch service identified one swarm that was up to 60km long and 40km wide – roughly the size of Luxembourg. The swarm was made up of up to 20bn individual locusts, officials said. www.carbonbrief.org/qa-are-the-2019-20-locust-swarms-linked-to-climate-change |
