Drought is a prolonged period of abnormally low rainfall, leading to scarcity of water resources. It can cause water shortages, agricultural problems, and impact ecosystems and economies.
Lack of vegetation to hold soil in place, reduced soil moisture making it more vulnerable to movement, and increased wind and water intensity due to dry conditions leading to erosion during a drought.
DroughtThe most common use of the term "drought" refers to meteorological drought, because that is the drought condition most familiar to the general public and the one most easily identified.
A drought occurs when there is a prolonged period of below-average precipitation, leading to a shortage of water resources. Factors such as climate variability, deforestation, and human activities can contribute to the onset and severity of droughts.
A lowering of the water table is most likely to occur during a period of prolonged drought or increased groundwater extraction. These conditions lead to decreased recharge of the aquifer and increased pumping, causing the water table to drop.
A drought typically means little or significantly below-average rainfall for an extended period of time, leading to dry conditions and water scarcity.
