Rigamonti said another essential component of the fight is supporting the livelihoods of people in impacted areas. Huge swarms of locusts have been attacking farms and fields on the Italian island of Sardinia. Control operations were then undertaken in the summer breeding areas along both sides of the Indo-Pakistan border (May–February), Ethiopia (August onwards) and Yemen (July onwards). These areas could become sources of new swarms if not sprayed and create an upsurge. This will then provide data on where African governments can direct their spraying efforts, helping to control the hoppers before they swarm. , On 28 December 2019, several large, immature swarms were first reported to have crossed into Kenya from Somalia, entering through the towns of Mandera and El Wak. On 21 December, immature swarms from the north first arrived in northeast Kenya where they were seen southwest of Mandera. Most recently, there were large swarms in Argentina in 2019 and 2017. They have not had such an outbreak since the 1960s and is already on alert. How Is The Universe Accelerating If The Expansion Rate Is Dropping?

A Harvard Astronomer Is More Confident Than Ever That An Alien Probe Visited Us In 2017, Are Women More Cooperative Than Men? The supercomputer, funded by £35m of UK aid as part of its Weather and Climate Information Services for Africa programme, has successfully forecast the movement of locusts using data such as wind speed and direction, temperature, and humidity. A community volunteer uses a motorised spray to disperse pesticide on February 25, 2020 at a hatch ... [+] site near Isiolo town in Isiolo county, eastern Kenya, where locust nymphs have hatched en masse. They undergo extreme changes in behavior and appearance when there are a lot of other locusts in the same place. Researchers are now inputting data on soil moisture and vegetation cover to help predict where eggs have been laid and are likely to hatch and thrive. They will consume all the food in any given area and then migrate to seek another food source. The model has achieved 90% accuracy in forecasting the future locations of the swarms. In January 2019 one of the first swarms reached Yemen and it became one of the first breeding grounds for the desert locusts and caused them to spread more. Cyclones and increased rainfall in recent years in East Africa may have led to more plant growth, which allowed locusts to breed faster, leading to the current locust swarms, said Song.
