Annotation This book provides an independent and comprehensive review of World Bank irrigation lending and policy between 1948 and 1993. The Bank's role in irrigation lending has been large--more than $30 billion (in current U.S. dollars) spread over some 600 projects. Only 200 projects have been in place long enough to be assessed. The overall performance record is good, but there is room for improvement.The report finds that there are still pervasive problems in maintenance and operation. Operating chaos prevails in most large canal systems in the humid tropics. In drier areas, drainage is the biggest environmental problem associated with irrigation. The author argues for upgrading existing systems, improving service, involving irrigators, and saving water where it is scarce.

2002 has been designated the International Year of Ecotourism by the United Nations. The concept of ecotourism relates to tourism activities which observe and appreciate nature, which contribute to its conservation, and seek to minimise any negative impact on the natural and socio-cultural environment. The main objective of this publication is to disseminate good practices regarding the planning and management of ecotourism activities. It contains 55 case studies from 39 countries which demonstrate a wide range of successful initiatives. Each considers the stakeholders involved, objectives and strategies, funding, sustainability and monitoring aspects, problems encountered and solutions found in each project.
