Objective of the study

Existing knowledge and technology may well be limited within the political boundaries of one country while relevant information is freely available in other countries within the ecological boundaries of the arid zone. Afforestation of arid and semi-arid lands may be considered technically impossible in some areas yet be successfully practiced in others. The objective of the present study was to consider two countries, one with some experience and the other with pressing problems of arid zone development, and to compare and contrast them in terms of environmental, technical, social, and economic factors with a view to identifying constraints to tree planting and to identifying areas in which national institutions and international agencies including the United Nations University could contribute by training and the dissemination of knowledge. In both of the countries chosen there is poor awareness and distribution of relevant literature, and throughout this report an attempt is made to draw attention to published information from these and other countries, particularly the technical and environmental literature.

The study transects two other sets of activities of the United Nations University in addition to the work on arid lands, namely fuelwood and agro-forestry. Fuelwood is a major forest product required in most of the developing world, and especially in the arid zone; agro-forestry, the combination of agricultural and forest crops, is one approach to land use and afforestation in the zone,
