The fourth edition of the World Water Development Report (WWDR4), ‘Managing Water under Uncertainty and Risk’ is a comprehensive review of the world's freshwater resources and seeks to demonstrate, among other messages, that water underpins all aspects of development, and that a coordinated approach to managing and allocating water is critical. The Report underlines that in order to meet multiple goals water needs to be an intrinsic element in decision-making across the whole development spectrum. It was launched at the 6th World Water Forum in Marseille by Irina Bokova, UNESCO Director General, and Michel Jarraud, UN-Water Chair.




Ecosystems can be managed so as to sustain water availability and its quality – services provided by ecosystems – and thereby help achieve water security. The continued availability of water (of sufficient quantity and quality) depends on the continued healthy functioning of the ecosystems that supply it, while the ecosystems themselves are dependent on receiving sufficient water. This can be summed up as ‘nature for water security; water security for nature’, a phrase that neatly encapsulates the linkages that decision-makers have to take into account.
