Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock. In this book, Henry Le Houérou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined.

This publication presents the proceedings of a regional technical meeting held in Budapest, Hungary from 6 to 10 March 2001. The meeting was organized and implemented by the Agricultural Research Institute of the Hungarian Academy of Sciences, Martonvasar, Hungary, in close collaboration with FAO's Seed and Plant Genetic Resources Service. In line with the Rome Declaration on World Food Security and the World Food Summit Plan of Action, the meeting recognized that one of the major challenges facing most countries in the region is the need to invest significant resources in strengthening their capacity to increase the availability of good quality seed of a wider range of plant varieties. This will contribute to the maximization of both agrobiodiversity and productivity, in order to achieve national food security while reducing environmental degradation and the depletion of natural resources."

This publication presents the proceedings a meeting organized and implemented by the Asia & Pacific Seed Association and the Department of Agricultural Extension of the Ministry of Agriculture in Bangkok, Thailand in close collaboration with the Seed and Plant Genetic Resources Service of the FAO. In line with the Rome Declaration on World Food Security and the World Food Summit Plan of Action, the Meeting recognized that one of the major challenges facing most countries in Asia and the Pacific is the need to invest significant resources into strengthening their capacity to increase the availability of good quality seeds of a wider range of plant varieties. This will contribute to the maximization of both agrobiodiversity and productivity, in order to achieve national food security while reducing environmental degradation and the depletion of natural resources. The Meeting proposed and agreed to establish a regional seed network to facilitate the exchange of information and expertise among countries and to coordinate policies and programmes designed to strengthen and improve local seed production and distribution systems in Asia and the Pacific. The Seed Network for Asia and the Pacific (SNAP) will facilitate inter-country scientific and technical collaboration on seed production and supply, and promote crop genetic resources evaluation, conservation and utilization in the region.
