Researches revealed that about 600 million people in Africa will be facing to clean
water deficit in less than 20 years unless the relevant measures are taken.
In the African Group countries, Cameroon stands out with the highest potential
of total renewable water resources. It is followed by Guinea, Nigeria, Gabon, and Sierra
Leone. Gambia and Niger have the lowest levels of annual readily renewable water
resources (Figure 7.3).
The average rate of groundwater resources to surface water resources is 30%. In
African countries, this ratio ranged from 6 to 52%. In this Group of countries, the
richest country in terms of the overall presence of water resources is Cameron (Figure
7.3).

With regard to storage capacities, capacities of existing dams in most of the
countries were found to be insufficient. Uganda and Mozambique are the countries with
the maximum water storage capacity (Annex 5).
