Detailed explanation-1: -Drought is a prolonged dry period in the natural climate cycle that can occur anywhere in the world. It is a slow onset phenomenon caused by a lack of rainfall. Compounding factors, such as poverty and inappropriate land use, increase vulnerability to drought.

Detailed explanation-2: -Drought is a long period without rains leading to a severe shortage of water in the region. The soil continues to lose water by evaporation and transpiration. If, however, it does rain at all or the rainfall is very low for a long period, the loss of water from the soil is not made up and hence the soil becomes dry.

Detailed explanation-3: -Drought results from changes in Earth’s atmosphere. Some droughts are caused by shifts in the winds that normally bring rain to an area. Others are caused by changing ocean currents, which affect the temperature and moisture of the air. Severe droughts can last for months or years.
