    Forests, trees and woodlands cover almost one-third of the Earth’s land area. They are a crucial source of food and income for more than a billion people around the globe. They provide a variety of wood and non-wood products and vital ecosystem services – preventing erosion from wind and water, preserving water quality, shading crops and livestock, absorbing carbon which contributes to countering climate change, and providing habitat for many species of plants and animals, thus helping to conserve the planet’s biological diversity.

    Agriculture in Eastern Europe and Central Asia is diverse, and has great potential to revitalize the economy of the countries in the region via improved productivity (efficiency) and higher total yield for food, fodder and fibre crops. Conservation agriculture can rise to the major challenge of making sustainable intensification of production systems a reality.

    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.

    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.

    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.

    The pressing need for increased agricultural production in the years ahead can only be met by more efficient use of our land and water resources including more widespread and better irrigation in those regions where rainfall is inadequate. Production gains will be shortlived unless the attendant hazards of salinization, water logging and lowered fertility are kept in check by effective planning and management based on a thorough understanding of the soil conditions. Soil survey and land classification are generally accepted essential preliminaries to investment in irrigation development.

    Policy makers as well as scientists have started to acquire an honest appreciation of the possibilities of reducing the wastage of materials which could be profitably utilized for improving or maintaining soil productivity. In addition, the great opportunities offered by making more efficient use of the potentials of biological nitrogen fixation in farming systems are now fully recognized. A number of recommendations and suggested guidelines were made by the various Working Groups during the two-week Workshop.
