    Results from this study show that the over-used but under-researched association between grazing and land degradation in the Kalahari has been oversimplified. In typical Kalahari conditions, the ecological changes that have been brought about by grazing cannot be linked with more fundamental changes in ecosystem function. Basic soil processes appear relatively unaffected by grazing pressure outside the sacrifice zone, and there is no evidence to suggest that the resilience of the system has been affected through soil degradation.

    Paper explores the relationships between the following concepts under the conditions of Middle Eastern semi-arid ecosystems. Paper states that there are two apparent contradictions in the title of this paper. First, grazing by domestic livestock is often considered to be hostile to nature conservation, especially in semi-arid areas (the ongoing conflict between ranchers and environmentalists in western USA is just one contemporary example of this).

    Will intensifying the road network around market areas produce greater economic returns and less environmental damage than extending the road network into new areas?Rural roads promote economic development but also facilitate deforestation. To explore the trade-offs between development and environmental damage posed by road building, Chomitz and Gray develop and estimate a spatially explicit model of land use.

    This study examines the land acquisition and distribution process of the Comprehensive Agrarian Reform Program (CARP) by analyzing the nature and extent of participation of the various government agencies. Attempts are also made in identifying the areas where land reform can be hastened. While there are opportunities for change, the paper concludes that the overall impact of these changes on land reform may not be as large in terms of area coverage.

    How do the spatial dynamics of the socialist city compare with those of the market city? What happens to a city when all investment decisions are made without land markets? What are the outcomes when the forces described by familiar urban models are not allowed to work?Bertaud and Renaud describe the structure of Russian cities after 70 years of Soviet development.

    This study focuses on the responses of pasture leases to the possibility of agrarian reforms by using the survey of 145 pasture leases in Masbate, Bukidnon and South Cotabato where pasture leases where concentrated. This paper relies mainly on the descriptive method of analysis. Results indicate the opening up of pasture leases to bidding for the most productive use of the land subject to the clear-cut regulations that such activities be environmentally and economically sustainable.

    Proposed here is a new scheme for allocating international river water that accounts for the stochastic nature of water supply and the dynamic nature of its demand. The suggested scheme is expected to improve the efficiency of river basins' water allocation and the riparians' welfare.International river and lake basins constitute about 47 percent of the world's continental land area, a proportion that increases to about 60 percent in Africa, Asia, and South America.

    This paper focuses on extracts from a recent comparative analysis of livestock and land use surveys across a range of agro-climatic conditions in sub-Saharan Africa, based on information from systematic low level aerial reconnaissance and complementary ground studies in Mali, Niger, Nigeria, Sudan and Tchad, between 1980 and 1993.

    Commercial farms in South Africa could become significantly more efficient if they became smaller. The government could encourage that trend by removing policies and distortions that favor large over small farms.Drawing on international evidence, van Zyl, Binswanger, and Thirtle discuss the sources of economies of scale.
