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] The rainfall in sub-Saharan Africa is highly seasonal and unevenly distributed, leading to ...
Financing. Out of the $4.7 billion of investments in water supply and sanitation in sub-Saharan Africa, 70% is financed internally and only 30% is financed externally (2001-2005 average).
