USA HISTORY

Detailed explanation-1: -Different disciplines have different definitions of drought. In agriculture, droughts are said to occur if the supply of moisture from precipitation or soil storage is inadequate to maintain optimum crop development. A prolonged rainless period may not be classified as a drought if crop yield is not visibly affected.

Detailed explanation-2: -With nearly 1.3 billion people – 40 percent of the world – relying on agriculture as the main source of income, drought is putting the livelihood of many at risk, often halting and reversing gains in food security and poverty reduction and hampering efforts to reach SDG1 and SDG2.

Detailed explanation-3: -Drought is a prolonged dry period in the natural climate cycle that can occur anywhere in the world. It is a slow-onset disaster characterized by the lack of precipitation, resulting in a water shortage. Drought can have a serious impact on health, agriculture, economies, energy and the environment.

Detailed explanation-4: -Reduced groundwater supply, decreased flow, and crop loss can all be a result of dry soil or arid conditions. When the water in the reservoirs runs out, crops are no longer flushed, which would deprive them of ground water.
