Drought is a complex phenomenon which is difficult to monitor and define. Hurricanes, for example, have a definite beginning and end and can easily be seen as they develop and move. Drought, on the other hand, is the absence of water. It is a creeping phenomenon that slowly sneaks up and impacts many sectors of the economy, and operates on many different time scales. As a result, the climatological community has defined four types of drought: 1) meteorological drought, 2) hydrological drought, 3) agricultural drought, and 4) socioeconomic drought. Meteorological drought happens when dry weather patterns dominate an area. Hydrological drought occurs when low water supply becomes evident, especially in streams, reservoirs, and groundwater levels, usually after many months of meteorological drought. Agricultural drought happens when crops become affected. And socioeconomic drought relates the supply and demand of various commodities to drought. Meteorological drought can begin and end rapidly, while hydrological drought takes much longer to develop and then recover. Many different indices have been developed over the decades to measure drought in these various sectors. The U.S. Drought Monitor depicts drought integrated across all time scales and differentiates between agricultural and hydrological impacts.

Drought➫ A natural disaster of below-average precipitation in a given region resulting in prolonged shortages in the water supply.
♦ When it occurs their food supply can shrink & their habitat can be damaged.
♦ A drought can last for months or years, or may be declared after as few as 15 days.
➧ Types 0f Drought are:-

[1] Meteorological Drought:-
❱ The magnitude of a precipitation shortfall & the duration of this shortfall event.
[2] Hydrological Drought:-
❱ The deficiencies in surface & sub-surface water supplies leading to a lack of water for normal & specific needs.
[3] Agricultural Drought
❱ The circumstances when soil moisture is insufficient & results in the lack of crop growth & production.
[4] Socio-Economic Drought:-
❱ The demand of some Economic good with elements of Meteorological, agricultural & Hydrological drought.
➧ Causes 0f Drought are:-
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=⤵
❱ Land & water temperatures cause drought.
❱ Air circulation & weather patterns also cause drought.
❱ Soil moisture levels also contribute to drought.
❱ It can also be a supply & demand of water issue.
➧ Effects 0f Drought are:-
