RECOMMENDATIONS:
Cities must protect and restore ecosystems that are important as key water sources. This will provide cheaper, more efficient and flood resilient water supply systems for the fast urbanising region of Africa. Cities must reduce water consumption and recycle waste- water inside cities, restore adjacent watersheds and improve engineering solutions to supply water from well-managed ecosystems.
Tackle Immediate Consequences
Countries must adopt a multi-sectoral approach to water and wastewater management as a matter of urgency, by incorporating principles of ecosystem-based management from the watersheds into the sea, and connecting sectors that will reap immediate benefits from better water and wastewater management.
Ecosystem protection, management and restoration provide a central, effective, sustainable and economically viable solution to enhancing water supply and quality while mitigating effects of extreme weather events of too much and too little water.
Successful and sustainable management of wastewater to help support peri-urban agriculture is crucial for reducing water consumption, and requires a mix of innovative approaches that engage the public and private sector at local, national and transboundary scales. Planning processes should provide an enabling multi-scale environment for innovation, including at the community level with government oversight and public management.

Innovative financing of appropriate water and wastewater infrastructure should incorporate design, construction, operation, maintenance, upgrading and/or decommissioning. Financing should take account the important livelihood opportunities in improving wastewater treatment processes, while the private sector can have an important role in operational efficiency under appropriate public guidance, including ecosystem restoration projects.
4 8 Towards the Future
In light of rapid global climatic changes, communities should plan water management against future scenarios, including extreme events of too much and too little water combined with rapidly growing urban populations.
Solutions for smart water and waste management must be socially and culturally appropriate and acceptable, as well as economically and environmentally viable. Ecosystem protection, management and restoration are the cheapest, easiest and most effective ways of improving and securing water supply, filtration and quality including re-use of wastewater for irrigation.

Education must play a central role in water management and in reducing overall volumes and harmful content of wastewater so that solutions are sustainable.
