Focal point
Location
The Food and Agriculture Organization of the United Nations leads international efforts to defeat hunger. Serving both developed and developing countries, FAO acts as a neutral forum where all nations meet as equals to negotiate agreements and debate policy. FAO is also a source of knowledge and information. We help developing countries and countries in transition modernize and improve agriculture, forestry and fisheries practices and ensure good nutrition for all. Since our founding in 1945, we have focused special attention on developing rural areas, home to 70 percent of the world's poor and hungry people.

Improved production systems as an alternative to shifting cultivation
Shifting cultivation, under its diverse forms of slash and burn system, is a traditional method of cultivating tropical upland soils, mostly for subsistence purposes. This traditional system of cultivation is in ecological balance with the environment and does not irreversibly degrade the soil resource, provided a sufficient length of fallow is allowed for soil restoration. However, increasing population pressures necessitate more intensive use of land. The consequence is extended cropping periods and shortened fallows.
Lesser-known tropical wood species
Freezaillah B.C. Yeom of Malaysia, drawing upon his experience as a forest-resources manager in Southeast Asia, evaluates available information and weighs both positive and negative aspects of the development of lesser-known species within the wider context of resource-management efforts. From the United States, James S. Bethel, with extensive practical forestry experience at both national and international levels, evaluates, from the standpoint of the user, the facts and the conclusions that he and other well-known experts in the field of forest-resource development have drawn from them.
