The main causes of water scarcity in Africa are physical and economic water scarcity, rapid population growth, and the effects of climate change on the water cycle. Water scarcity is the lack of fresh water resources to meet the standard water demand . [ 1 ]
Communal tap (standpost) for drinking water in Soweto, Johannesburg, South Africa. May 2005. Groundwater plays a key role in sustaining water supplies and livelihoods in sub-Saharan Africa especially due to its widespread availability, generally high quality, and intrinsic ability to buffer episodes of drought and increasing climate variability.
Map of global water stress (a symptom of water scarcity) in 2019. Water stress is the ratio of water use relative to water availability and is therefore a demand-driven scarcity. [1] Water scarcity (closely related to water stress or water crisis) is the lack of fresh water resources to meet the standard water demand. There are two types of ...

Sand and water on the side of the road, causing erosion on the environment Plastic bags dumped by the road side in Katete in mbarara district in western Uganda. The erosion caused by rains, rivers and winds as well as over-use of soils for agriculture and low use of manures have resulted in turning the soils infertile, as for example, in the plains of the Nile and the Orange River.

The current water crisis is a result of the deteriorated state of the water infrastructure due to underinvestment in the water sector and conflict-related destruction as well as the rapid growth of the population, which was estimated at 4 percent in urban areas and 2.5 percent in rural areas by the World Bank in 2009.
The water cycle is an important system that moves the water on Earth around, cycling it continuously between the atmosphere, rivers, oceans, lakes, and glaciers, and groundwater supplies. This pattern is crucial aspect of how the Earth systems work, contributing weather patterns as we know them. [5]
