WWDR4 was released at the 6th World Water Forum held in Marseilles, France. It is updated from previous editions with a new emphasis on how water relates to other international development topics such as: water supplies, uses, management, institutions and financing, regional hotspots, gender equality, disaster preparedness, heath, and environmental ecosystems. The report advocates that water be included in "decision-marking across the whole development spectrum" and not be placed in a "water box" exclusive of other public policy decisions.
WWDR4 cites as the following three examples as potential hydropower solutions in Africa:
- Southern African Power Pool (SAPP), founded in 1995 is under the authority of the Southern African Development Community. It was 12 members including: Angola, Botswana, the Democratic Republic of Congo, Lesotho, Mozambique, Malawi, Namibia, South Africa, Swaziland, Tanzania, Zambia, and Zimbabwe.
- Western African Power Pool founded in 2000 is under the authority of the Economic Community of West African States. It has 13 member including: Benin, Burkina Faso, Cape Verde, Cote d'Ivoire, Gambia, Guinea, Guinea Bissau, Liberia, Mali, Nigeria, Senegal, Sierra Leone, and Togo.
- The projected expansion of Inga hydroelectric dams in the Democratic Republic of Congo has the potential to generate 80% of the electricity used in Africa by 2020.
