In Africa, natural disasters include, first of all, permanent droughts, during which there is a long and significant lack of precipitation, usually at high temperatures and low humidity. Especially often droughts occur in the savannah zone of North and East Africa. Droughts are accompanied by a dry wind – a...wind that carries thousands of kilometers of hot and dry air. With him, he carries a lot of grains of sand and dust. Droughts and dry winds lead to crop losses, pasture loss and, as a result, people’s hunger in many African countries. Sandstorms in deserts fill with sand the wells, caravan routes.
The locust invasion inflicts great harm. As a rule, these insects lead a solitary and sedentary lifestyle. But sometimes locusts gather in huge camps and fly thousands of kilometers, destroying crops along the way in large areas.
