Famine, on the other hand, is caused by a decline in availability of and/or access to food often caused by one of the three kinds of drought. Where there is insufficient water to produce a staple crop, for example, or where there is insufficient fertilizer to produce the standard yield for a crop, drought may lead to and certainly cause famine.
Lack of rainfall which is likely to cause drought. Deforestation as a result of cutting down of trees. Drying out of rivers and lakes. Weather patterns as well as air circulation. Depletion of soil moisture level.
Drought also creates large amount of dust. Dust in agricultural areas is full of toxic chemicals used to fertilize soil or rid it of pests.
This begs the inquiry “What are the causes and effects of drought?”
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.
Because drought is defined as a deficit in water supply, it can be caused by a number of factors. The most important one though relates to the amount of water vapor in the atmosphere as this is what creates precipitation. More rain, sleet, hail, and snow can occur where there are moist, low-pressure air systems.
What are some interesting facts about droughts?
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.
Why is Madagascar facing its worst drought in 40 years?

The lack of rainfall and other environmental factors have taken a toll on the region’s vegetation and agricultural production, leaving many in the region facing severe hunger.
Why are Madagascar’s dams so dry?
Severe drought conditions during southern Madagascar’s rainy season from November 2017 to April 2018 has led to nearly dry dams in many parts of the south.
