    Five themes are identified for social, economic and policy research relating to miombo woodland management in southern Africa. They are: (1) patterns of local institutional change; (2) household use of woodland products; (3) markets for woodland products; (4) longer term dimensions to woodland use and exploitation and (5) policy and legislation. These themes are by no means definitive or exhaustive, but are described here as a means of focusing on the scope of future research, and as a basis for identifying priorities.

    Níger, África, África occidental

    This research was undertaken as a Ph.D. dissertation (Stanford University) in conjunction with the ILCA programme in Niamey, Niger. The objective of the research was similar to that of the World Bank studies: to test how land tenure affects land-improving investment, agricultural productivity and resource management. The standard hypothesis is that land tenure that is non-exclusive insecure or non-transferable will lead to under-investment and depressed factor mobility.

    Large areas of land are presently cleared of their natural cover, endangering the worldwide ecosystem. Land clearing, if necessary, should be carried out with great care after very careful consideration. Different land types require different clearing techniques. Often, soil needs to be stabilized after clearing. All clearing processes require training of persons involved.
