Meteorological droughts occur when dry weather patterns dominate an area. Hydrological droughts refer to when low water supply becomes evident in the water systemAgricultural droughts happen when crops become affected by drought. Socioeconomic droughts occur when the supply and demand of various commodities is affected by drought., and more items.
They are: Meteorological drought – that is caused by shortage of precipitation or rainfall. Agricultural drought – that is caused by lack of moisture in the soil. Hydrological drought – that is caused by low levels of water in various water sources like rivers, lakes, etc. Socioeconomic drought – that is caused by shortage of tap and drinking water.
