Drought is a condition of abnormally dry weather within a geographic region. Drought refers to the lack of enough rain for an extended period of time in a specific region. During droughts, rainfall is less than normal, causing a water imbalance and resultant water shortage. It occurs when the rate of evaporation and transpiration exceeds precipitation for a considerable period. The effects of drought begin with acute water shortage, water-supply reservoirs becoming empty, and wells drying up. Groundwater level is also depleted, soil degradation and erosion occurs and there is extensive crop damage. People might become impoverished and diseases may spread due to malnutrition.
