Africa sits on huge underground water reserves which contain 100 times the amount of fresh water resources on the surface, according to a new comprehensive map.
Does Africa have water underground?
Groundwater reserves in Africa are estimated to be 20 times larger than the water stored in lakes and reservoirs above ground. … They are a vital source of drinking water in sub-Saharan Africa, where groundwater is often the only year-round supply of fresh water in rural areas.
How deep is the water table in Africa?
The researchers say some of the largest deposits are in the driest areas of Africa in and around the Sahara, but they are deep – at 100 to 250 meters below ground level.
How much groundwater is there in Africa?
The study estimates the scale of the continent’s groundwater resources at around 0.66 million km3. This volume, the authors explain, is “more than 100 times the annual renewable freshwater resources, and 20 times the freshwater stored in African lakes.”
Is there actually water in Africa?
The irony is that Africa has abundant fresh water: large lakes, big rivers, vast wetlands and limited but widespread groundwater. Only 4 per cent of the continent’s available fresh water is currently being used.
Is there water underneath the Sahara?
The Sahara has only two permanent rivers and a handful of lakes, but it has substantial underground reservoirs, or aquifers. Its permanent rivers are the Nile and the Niger.
Is there water in the Sahara?

Where is Africa’s water found?
Africa appears blessed with abundant water resources: large rivers include the Congo, Nile, Zambezi and Niger and Lake Victoria is the world’s second largest.
Where does water come from in Africa?
It is estimated that over 40% of Africans use groundwater as their main source of drinking water, particularly in North and Southern African countries. Piped water is still the most important source of drinking water (39%) in urban areas, yet boreholes are becoming more important (24%).
Where is groundwater found in Africa?
“Where there’s greatest ground water storage is in northern Africa, in the large sedimentary basins, in Libya, Algeria and Chad,” she said. “The amount of storage in those basins is equivalent to 75m thickness of water across that area – it’s a huge amount.”
Is groundwater the cleanest water?
Unlike surface water collected in rivers and lakes, groundwater is often clean and ready to drink. This is because the soil actually filters the water. The soil can hold onto pollutants—such as living organisms, harmful chemicals and minerals—and only let the clean water through.
Does Somalia have underground water?
Groundwater is of huge importance in Somalia. Apart from the areas along the Juba and Shabelle Rivers, all regions depend on groundwater for domestic water supply, livestock and small scale irrigation.
How does Africa use groundwater?
Groundwater is the main source of water for drinking, cooking and sanitation for most people in Africa, especially in the dry season – for both rural and much of urban populations.
Why is there no water in Africa?
The main causes of water scarcity in Africa are physical and economic scarcity, rapid population growth, and climate change. Water scarcity is the lack of fresh water resources to meet the standard water demand.
How do African villages get water?
Groundwater is the best resource to tap to provide clean water to the majority of areas in Africa, especially rural Africa, and groundwater has the benefit of being naturally protected from bacterial contamination and is a reliable source during droughts.
