The publication, Mountains of the World: Water Towers for the 21st Century, elaborates on the interrelationship between mountains and fresh water. Although many in-depth hydrological studies have been carried out, a global overview of the contribution mountains make to the supply of water to humankind has been notably absent. This publication presents a compilation of case studies, together with an overview of the important role of mountains in supplying fresh water to the world, and a summary of the main challenges to be faced in maintaining these water towers for the 21st century.
This report is a small contribution to Chapter 13 on mountains, and Chapter 18 on water in Agenda 21. It is intended to create a better understanding of the linkages between water and mountains and to foster the need for recognition of the important role mountains play in the water cycle. It highlights the necessity of strong stewardship by mountain populations as well as the responsibility of downstream communities and nations for the sustainable management of mountain water resources.
