The resulting low dam levels led to water restrictions being imposed on users across several countries in Southern Africa. Additional impacts of the drought are death of livestock and poor crop yields due to poor or no rainfall making water unavailable for irrigation.
What are 3 consequences of drought in Africa?
Anxiety or depression about economic losses caused by drought. Health problems related to low water flows and poor water quality. Health problems related to dust. Loss of human life.
What effects do droughts have?

What are the causes and effects of droughts?
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.
Why are droughts so dangerous?
As run-off reduces during drought, water bodies such as rivers/burns, lakes/lochs, streams, and reservoirs, also become low. … Low water levels, higher nutrient levels and increased water temperatures lead to algal blooms which can be harmful to human health.

Areas that rely on rainfall and surface water are more likely to experience drought. Surface water quickly evaporates in warm, dry conditions leading to an increased risk of drought.
What are the causes of drought in southern Africa?
One of the main causes of drought in South Africa is the variability in rainfall (Mason and Tyson, 2000; Tyson and Preston-Whyte, 2000 and Vogel et al., 2000). The El Niño phenomenon accounts for approximately thirty percent of rainfall variability (Tyson and Preston-Whyte, 2000).
How can we prevent droughts?
