There are four types of drought:
1. Meteorological drought: occurs when an area experiences a prolonged period of below-average precipitation. This type of drought can also be caused by high temperatures, strong winds, and low humidity, as these factors can increase evaporation and lead to a lack of moisture in the soil and vegetation.
2. Agricultural drought: is characterized by a lack of moisture in the soil that can result in reduced crop yields, poor quality crops or even crop failure. This type of drought affects farmers and the agricultural industry, and can have a significant impact on food supply and prices.
3. Hydrological drought: occurs when surface water and groundwater sources are reduced to below normal levels. This can lead to decreased stream flows, reduced lake and reservoir levels, and even dry wells. Hydrological droughts can have devastating effects on aquatic ecosystems, as well as drinking water supplies and the economy.
4. Socioeconomic drought: is a complex type of drought that takes into account the social and economic impacts of drought on human populations. This type of drought can result in decreased economic productivity, increased unemployment, decreased availability of food and water, and even social unrest.
