    This paper reports on research conducted for the Indigenous Land Corporation, an Australian government agency concerned with the acquisition and management of lands for indigenous peoples. The paper seeks to identify and analyze the kinds of institutional arrangements that might be deployed to support indigenous communities in the management of indigenous-owned land. It is concerned with a particular planning context in which the role of state agencies is focused on supporting and facilitating the work of indigenous landowners.

    Today, there are only about 15,000 black farmers in the United States. Declining by 98 percent since 1920, black farmers have suffered losses attributable to public policy, economic pressures, and racial oppression. All of these factors must be addressed if African-American farmers are to survive. In this paper, we use Census of Agriculture data and a follow-on survey in one Mississippi Delta county to review the current situation of black farmers.

    There is little empirical evidence concerning the effects of intellectual property rights (IPR) on a technologically advanced developing country. Complete enumeration of the Mexican maize breeding industry showed that, contrary to the hypothesis that IPR would provide, in a technologically advanced developing country, incentives for R&D and innovation, IPR play no role for the industry in general, but that they are important for certain breeders' categories. The paper presents the theory on IPR and a short background on the Mexican maize breeding industry.

    Leafy spurge is an exotic, noxious, perennial weed which is widely established in the north central United States and is an especially serious problem in the northern Great Plains (Bangsund et al. 1999). In 1997, the Agriculture Research Service and Animal Plant Health Inspection Service, U.S. Department of Agriculture, initiated a major Integrated Pest Management (IPM) research and demonstration project to develop and demonstrate ecologically based IPM strategies that can produce effective, affordable leafy spurge control.

    We offer a practical test of local government effectiveness in the provision of public services. Building on the work of Brueckner (1979, 1982, 1983) and Henderson (1990, 1995) we offer a property value maximization model where levels of local public services are capitalized into property values. Using data for Wisconsin municipalities we demonstrate that service expenditure levels, and corresponding taxation levels, should be increased. In other words, the property value maximization test suggests that local public services in Wisconsin are consistently under-provided.

    This paper presents estimates of the benefits and costs of alternative soil conservation policies in a spatially and temporally consistent framework. The policies considered are implementation of soil conservation practices with an objective of reducing erosion to a site's tolerance level and a policy with an objective of a voluntary 50% reduction in conventional tillage. Costs and erosion benefits of these two policies are compared with that obtained from CRP. The changes in erosion and cost are estimated relative to 1992 levels.

    Malawi

    This paper uses cross section-time series data on 57 communities in Malawi to determine statistically the factors determining changes in land use, tree cover, and crop yield. The econometric model is developed from a theoretical model which also endogenizes population growth and prevailing land tenure institutions within the customary sector of Malawi. The analysis reflects changes between 1971 and 1995, utilizing aerial photos taken at these dates and complementing these with field surveys.

    The conceptual model necessary for an assessment of biotechnology's economic benefits and costs is outlined, emphasizing the need to account for the proprietary nature of biotechnology innovations. The model is illustrated with an application to Roundup Ready soybeans. The estimated value of this innovation is sizeable, with consumers and innovators claiming the larger share of net benefits. Also, disparities in intellectual property rights protection across countries affect the distribution of benefits.

    Proposals to close the Minneapolis Upper Harbor, and convert the area to housing, light industry and recreational uses, would eliminate the barge movement of commodities to/from the Upper Harbor. Several proposals have assumed that this would also eliminate associated freight movement through this area of Minneapolis. However, there would still be a need to move materials such as sand and gravel, cement, steel products, and other construction materials into Minneapolis; and scrap metals from Minneapolis.
