Presents two alternative scenarios of water demand and supply for 118 countries over the 1990 to 2025 period and develops indicators of water scarcity for each country and for the world as a whole. This study is the first step in IWMI's long-term research goal: to determine the extent and depth o...

Discusses and illustrates concepts for identifying ways of improving productivity of water within basins. The results of applying a water accounting procedure to four sub-basins in South Asia (Bhakra in India; Chishtian in Pakistan; Huruluwewa in nothern Sri Lanka; and Kirindi Oya in southern Sri...

Changes in the way water is used in one part of a river basin often affect how water is used somewhere else in that basin. This report introduces the concept of hydronomic ( hydro water + nomus management) zones that were developed to help untangle some of the complexities of basin-wide water res...
