The performance of many canal irrigation delivery systems is unsatisfactory in terms of: (i) water resources management; (ii) service to irrigated agriculture; and (iii) costeffectiveness of infrastructure management. In recent years, participatory approaches and management transfer reforms have been promoted as part of the solution for more cost-effective and sustainable irrigation services. Large agency-managed systems have been turned over partially or completely to various types of management bodies. However, the results have usually been disappointing.

This double issue of Unasylva aims to tease out the complex interrelationship between forests, trees and disasters, and to examine the ways in which forests and trees can best be managed both to resist shocks and to protect from shocks. Forests and trees can act as natural buffers against disasters and shocks. They have a powerful role to play in protecting against disasters and in reducing their impact. Indeed, the long-term perspective implicit in sustainable forest management is also a valuable approach to planning for disaster risk reduction.

To produce the desired results, therefore, watershed management efforts must incorporate "forest hydrology", "soil and water conservation" and "land use planning" into a broader, logical framework that takes into consideration not only physical interrelationships but economic, social and institutional factors as well. In this issue, Unasylva examines several facets of watershed management.

Ce double numéro d’Unasylva se propose de sonder les relations complexes existant entre les forêts, les arbres et les catastrophes, et d’examiner comment il est possible de gérer au mieux les forêts et les arbres à la fois pour résister aux chocs et pour protéger contre les chocs. Les forêts et les arbres peuvent servir de tampons naturels contre les catastrophes et les chocs. Ils ont un rôle déterminant à jouer dans la protection contre les catastrophes et la réduction de leur impact.

This publication has been prepared as a background paper in view of the UN conference on the human environment that was held in Stockholm in 1972. This background document had contribution from UNESCO, IAEA and WHO. While the demand for land for land increases at a very rapid rate through population growth, technological progress and industrial development, soil resources remain fixed. The maintenance of their productivity is therefore of paramount importance.

Extensive grazing is the predominant form of land use on at least a quarter of the world’s land surface, in which livestock are raised on food that comes mainly from rangelands. Extensive grazing differs from crop or forestry production, in which the produce remains in situ whilst growing. Evaluation for extensive grazing, unlike that for cropping or forestry, must take into account the production of both grazing forage, termed primary production, and the livestock that feed on this forage, termed secondary production.
