The world's water - Is there enough?

This booklet, a contribution to World Water Day 1997, was published jointly with the United Nations Educational, Scientific and Cultural Organization (UNESCO). It outlines the issues of assessment of the world's freshwater supply and the availability and use of that water's resources. Its purpose is to draw the attention of all concerned to the urgent need to enhance the monitoring and assessment of water resources in rivers and aquifers, particularly in basins shared regionally or internationally.
