Green Hills, Blue Cities: An Ecosystems Approach to Water Resources Management for African Cities. A Rapid Response Assessment

Green Hills, Blue Cities: An Ecosystems Approach to Water Resources Management for African Cities. A Rapid Response Assessment
  • United Nations Environment Programme (UNEP), United Nations Human Settlements Programme (UN-Habitat). March 2011
  • This report shows that there is a way forward for a more sustainable future where restoration of ecosystems, often in the green hills and watersheds surrounding cities, can provide cheaper, efficient and resilient water supply systems in a changing world. The case studies provided in this report present urban water challenges in African cities, and highlight approaches adopted to reduce the impacts of urbanisation on water and ecosystems. Seven case studies discuss urbanisation characteristics of their respective cities, state and trends of water withdrawals and demand, environmental impacts of bulk water supply and wastewater discharge, and lessons for policy.
