What are the causes of droughts?

A drought is an event of prolonged shortages in the water supply or lack or insufficiency of rain for an extended period of time.

Causes of Droughts are:


1. Deforestation reduces the amount of water stored in the soil, as rain falls on the soil it leads to soil erosion and creates desertification which can lead to drought.

2. Low surface water flows using surface water in large amounts to irrigate crops and for various other human activities, results in drying up of groundwater, lakes, and rivers.

3. Global Warming emission of greenhouse gases such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and chlorofluorocarbons (CFCs) which increases the Earth’s temperature results in increased evaporation and less rainfall which leads to the drought.

4. Air Circulation and Weather Patterns water are stored in the ground and also in the air. Weather patterns rotate the water in the air which is sometimes gets delayed to reach in certain regions and leads to the drought in those regions.
