ENVIRONMENT STRATEGY PAPERS NO. 2 Environmental and Water Resources Management Rafik Hirji Hans Olav Ibrekk October 2001 The International Bank for Reconstruction and Development/THE WORLD BANK 1818 H Street, N.W. Washington, D.C. 20433, U.S.A. Manufactured in the United States of America First printing October 2001 In 2001, the World Bank completed the comprehensive two-year process of preparing its Environment Strategy, Making Sustainable Commitments: An Environment Strategy for the World Bank. It was endorsed by the Bank’s Board of Directors and published in October 2001. Several background papers were prepared and published by the Bank’s Environment Department to stimulate constructive dialogue and intellectual discussion on a range of issues within the Bank as well as with client countries, partners, and other interested stakeholders. The Environment Strategy Paper series includes revised versions of Environment Strategy background papers, as well as new reports prepared to facilitate implementation of the Strategy. This series aims to provide a forum for discussion on a range of issues related to the strategy, to help the transfer of good practices across countries and regions, and to seek effective ways of improving the Bank’s environmental performance.
