This report introduces new aspects of water issues: 1) it reintroduces the 12 challenge area reports that provided the foundation for the first two World Water Development Reports (WWDR); 2) 4 new reports on water quality, groundwater, gender, and desertification, land degradation and drought; 3) in recognition that the global challenges of water can vary considerably across countries and regions, a series of 5 regional reports have been included; 4) a deeper analysis of the main external forces of freshwater resources and possibilities for their future evolution; 5) managing water under uncertainty and risk.
- In a world that is changing faster than ever in often unforeseeable ways, with increasing uncertainties and risks, historical experience will no longer be sufficient to approximate the relationship between the quantities of available water and shifting future demands.
- Country-level case studies presented describe the progress made in meeting water-related objectives.
- Water has a central role in all aspects of economic development and social welfare. Concerted action via a collective approach of the water-using sectors is needed to ensure that water's many benefits are maximized and shared equitably and that water-related development goals are achieved.
