How can we stop drought in Africa?
Protection and use of springs; Cloud seeding; Evaporation suppression; Desalination of brackish groundwater or sea water; and Effluent treatment and re-use. Developing and integrating other sources like groundwater, desalination and re-use, etc., with surface systems also to enhance water security.
How can we reduce the impact of droughts?
Cover Crops – Planting or maintaining vegetation, living or dead, will provide cover on the soil surface and reduce erosion. Low-water using plants like barley are typically used as cover crops during droughts.

What are causes of drought?
The Short Answer: A drought is caused by drier than normal conditions that can eventually lead to water supply problems. Really hot temperatures can make a drought worse by evaporating moisture from the soil. A drought is a prolonged period with less-than-average amounts of rain or snow in a particular region.
What are the impacts of the drought?
Examples of drought impacts on society include anxiety or depression about economic losses, conflicts when there is not enough water, reduced incomes, fewer recreational activities, higher incidents of heat stroke, and even loss of human life. Drought conditions can also provide a substantial increase in wildfire risk.
Why is it important to reduce droughts?
Reduced water availability to different sectors leading to environmental, health, social and economic impacts. Droughts can impact electricity supply, due to reduced water availability for hydropower generation and for cooling of thermoelectric (e.g. nuclear, fossil-, biomass-fuelled) power generation.
What are 5 causes of drought?
Here are the 5 natural and human causes of drought:
- 1) Land and water temperatures cause drought.
- 2) Air circulation and weather patterns also cause drought.
- 3) Soil moisture levels also contribute to drought.
- 4) Drought can also be a supply and demand of water issue.
What are the causes and effects of drought?
The soil starts drying out and plants die. When this pattern continues for several weeks, months or years, the flow of streams and rivers decreases and water levels in lakes, reservoirs and wells fall. Eventually, the unusual dry weather causes water supply issues, and the dry period becomes a drought.

How does a lack of water affect agriculture?
Agricultural drought begins when a lack of water kills crops and livestock, affecting locals’ survival. The timing of declaring a drought can often be very subjective and highly political. Forecast mechanisms require quality data and local knowledge to understand how dry conditions will impact water and food supplies.
