    A concise summary of the state of knowledge and experience concerning sustainable forest management, prepared as an input to the World Bank's Forest Policy Implementation Review and Strategy. An overview of experiences gained from different forest management systems is given, followed by a discussion of the outlook for forest resources and for forest product markets. Market, policy and institutional failure is analysed and appropriate responses are outlined. Finally, approaches to international co-operation are discussed.

    The effects of land-use change on the structure of Oxisols in the Brazilian savannas (also known as the Cerrados) are still insufficiently understood. We therefore studied loamy and clayey Oxisols under natural savanna, crop, pasture, and reforestation to (1) quantify management-induced changes in the quantity of water-stable aggregates, (2) identify the main aggregating agents, and (3) correlate aggregation with changes in pore-size distribution. Clayey soils showed a significantly higher macroaggregation than did loamy soils.

    This report presents the results of an analysis of economic rent from roundwood production in Suriname. It starts by describing the concept of economic rent: what it means; how it is calculated; and why it is so important. it then presents the results of the economic rent analysis and presents some recommendations for forest charges in Suriname. Later sections describe some ways to improve the efficiency and profitability of the forestry sector in Suriname and some ways that current constraints may be overcome.

    The effect of land use on the availability of soil nitrogen (N) was studied by separating total soil N into one labile and one stable fraction by oxidation and extraction of labile N with potassium permanganate. The nitrogen management index (NMI) was calculated according to Blair et al. (1995) for the carbon management index. In all systems, labile N released by potassium permanganate was a better indicator for nitrogen availability than were total and stable N. The NMI was a good indicator for N availability but gave no information on the total amount of N.

    This study is a revised version of a working document originally prepared by FAO in April 1995 analysing the policy and legal options available for dealing with the sensitive issue of foreign ownership of land. It provides information on the approaches that are, or have been adopted to regulate foreign ownership of land. As such, it aims at providing a framework for analysis and a representative sample of the legal techniques and strategies that have been devised to deal with the issue; it is not intended to be an authoritative summary of the state of the law in this area.

    In the Brazilian savannas, or Cerrados the rapid advance in agriculture and cattle ranching is affecting soils through, for example, accelerated erosion and depletion of soil organic matter (SOM). Changes in soil microbial biomass are good indicators of changes in SOM. We therefore assessed the effects of agricultural and pastoral use of a clayey Oxisol in the Cerrados on soil microbial biomass, and evaluated the usefulness of this parameter in studying SOM dynamics in savanna ecosystems.
