Final answer:
Africa and several major metropolitan areas around the world experience long periods of drought.
Step-by-step explanation:
Drought is an extended period of abnormally low precipitation that adversely affects water supply and ecosystems. It leads to water scarcity, crop failure, and environmental stress. Droughts can have severe socio-economic impacts, impacting agriculture, water resources, and ecosystems, often requiring mitigation measures and resource management.
A region that often experiences long periods of drought is Africa. On average, Africa is already the hottest continent in the world, and rainfall has decreased by 20 percent in its dry regions, exacerbating droughts. Countries in the Horn of Africa, like Kenya and Somalia, have been particularly affected by droughts. Additionally, many major metropolitan areas around the world, such as Delhi, Lagos, and Los Angeles, are projected to experience moderate to severe precipitation decrease and face water supply challenges in the future.
