The present issue of Forest Genetic Resources (FGR) goes to press immediately following the Eleventh World Forestry Congress held in Turkey 13-22 October 1997, which more than 4000 colleagues from 145 countries attended. In regard to the conservation and use of forest genetic resources, the Congress, in its deliberations and report, stressed that action to conserve, manage, sustainably utilize and enhance forest genetic resources is an urgent priority.

The Global Forest Resources Assessment 2000 (FRA 2000) provides a comprehensive and up-to-date view of the world's forest resources at the end of the second millennium. It is the result of the collective efforts of the countries of the world. This major undertaking was based primarily on information provided by the countries, supplemented by state-of-the-art technology to verify and analyse the information and to make the results accessible to the world through the Internet. The FRA 2000 process emphasized collaboration and transparency.

Drainage of agricultural land is one of the most critical water management tools for the sustainability of productive cropping systems, as frequently this sustainability is extremely dependent on the control of waterlogging and soil salinization in the rootzone of most crops. On some agricultural lands, the natural drainage is sufficient to maintain high productivity. However, many others require improvements in surface and subsurface drainage in order to optimize land productivity, while maintaining the quality of soil resources.

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.
