Climate change is affecting water supply in all parts of the world. Droughts are affecting agriculture and delivery of water for households and industries. Floods are damaging infrastructure and crops. Retaining water for later use will become more important to safeguard a reliable water supply, especially in cities where many users are located.

'Managing the Water Buffer for Development and Climate Change Adaptation' explains the 3R approach: Recharge, Retention and Reuse of water. It is a practical guide on how to maximize the use of groundwater and rainwater, for both arid and semi-arid areas. It provides insights in adaptation strategies from all over the world, and highlights the importance of local solutions as contribution to the regional or national adaptation policies.
