    Land quality in the man-modified agricultural landscapes of eastern Africa has been shown to degrade over time, resulting in higher demands for farm inputs in order to sustain productivity. Loss of biodiversity has also been observed in all these areas of land use change. It has therefore become important to know how land use change contributes to land degradation and how land use change leads to biodiversity loss. This paper from the collaborative LUCID project describes a framework for the analysis between land use change, biodiversity loss and land degradation for the first time.

    This paper looks at the dynamics of land and violent conflict. It states that conflict situations in rural societies deeply affect the politics of land, and that land requires a careful approach by policy makers because it is a central element in the evolution of societies. As a result, policies pertaining to land are not neutral in terms of conflict management.The paper argues that donors seeking to promote peace and development should tackle land issues in recipient countries more systematically, more carefully and in a more coherent manner.

    The notion of a reservation value is a key feature of most contemporary dynamic and stochastic models of land development. It is clear that the magnitude of the reservation value has a fundamental bearing on the decision to develop or preserve land. This notwithstanding, many papers that analyze land development in a dynamic and stochastic setting treat a landowner’s reservation value as an exogenous variable. Therefore, the purpose of this paper is to endogenize the reservation value in the context of a model of land development over time and under uncertainty.

    Land costs account for a significant proportion of the total costs for many agricultural products that are traded internationally, especially for the major grain crops that the U.S. exports in competition with several other countries. For owner-operators, a common form of tenure in the U.S. and most other countries, most land costs are implicit and involve few cash outlays, i.e., are opportunity costs that are important in the long-run but that may not affect production decisions in the short-run.

    We establish a procedure to track the tax valuation history of properties that are fully or partially restricted with conservation easements to test the assertion that easements result in lower property valuations. Easements didn't decrease property valuations; they merely decreased the rate of value for the affected properties. On average, the restricted properties' valuations increased at a rate lower than did those for unrestricted properties - but not always, and certainly not uniformly.

    In this paper we put forth some empirical evidence from the Brazilian Amazon that the relationship between roads and land clearing may be much more complex than the conventional wisdom implies. In particular we find that in areas that already at least partially cleared, improving the road network (i.e. decreasing transport costs) may actually decrease the rate of deforestation. We argue that our methodology of explicitly modeling the dynamics should be preferred to the more common static, contemporaneous analyses found in the literature.

    Public recreation land management agencies have been searching for ways to increase revenue. User fees as implemented by the Fee Demonstration Program have received the most attention. Corporate sponsorships and private donations have also been implemented and other options, such as partial privatization, closure of some areas, and different forms of public-private partnerships have been debated.

    This report is a summary of the data contained on the farmland sales portion of the Minnesota Land Economics (MLE) web site (http://www.apec.umn.edu/landeconomics) as of April 29, 2004. It is formally reissued each Spring, as new sales data become available. We no longer distribute a separate farm real estate report in the Minnesota Agricultural Economist (now the Minnesota Applied Economist: http://www.apec.umn.edu/MnApEc).
