Population pressures and the need to optimize the use of limited available land has led to increasing cropping affluence levels within the maize agro-ecologies in Kenya, and a shift from large to smallholder intensification and multiple cropping patterns. Using a geographic information system, this study relates cropping patterns, by area share, maize productivity and household incomes across maize agro-ecologies, with the purpose to establish a decision support system for optimizing land allocation and in priority setting for introduction of new technologies such as Bt maize varieties.

Soil erosion seriously threatens the future agricultural productivity of Ethiopia's highlands. In analyzing the determinants of soil conservation investments there, this study goes beyond the conventional physical factors to examine institutional, social capital and public program effects. The double hurdle statistical analysis from 250 farms in the Tigray region reveals different causal factors for soil conservation adoption versus intensity of use.The determinants of adoption of soil conservation measures vary sharply between stone terraces and soil bunds.

The effect of globalization on the environment and natural resource use in developing countries is hotly debated. We contribute to this debate through the analysis of primary data collected with small contract farmers in Madagascar that produce vegetables for export to Europe. Strong spillover effects of these trade opportunities on land use exist. Using a matched plot sampling design, the productivity of rice - the main domestically consumed staple - is shown to be two thirds higher on those fields that were contracted during the off-season for the production of vegetables.

The study analyzed the determinants of land tenure insecurity in Uganda using survey data collected by the International Food Policy Research Institute (IFPRI) during the Policies for Improved Land Management Project in Uganda, 1999-2001. The survey included a sample of 1322 farm households randomly selected and interviewed using a formal questionnaire.

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.

Beginning in January 1991, the U.S. Agency for International Development funded a series of studies on land, employment, and financial markets in the peri-urban areas of Maputo. Beginning in September 1991, a land-market survey involving 121 households and 162 plots of land was administered in two peri-urban green zones of Maputo-districts 4 and 6.

Although there is broad agreement that well functioning land rental markets will play an important role to increase productivity and household welfare as agrarian economies develop, evidence from Africa on the actual performance and impact of such markets is limited. We use data from Uganda to test for differences in the performance of rental, as compared to sales markets and their evolution over time, based on a framework where markets are affected by differences in ability and imperfections in rural labor and capital markets.

A taxonomy for describing property rights to natural resources is described and applied in a Zimbabwean case study. The taxonomy allows: tenures to be systematically compared and contrasted; incentives for natural resource management to be identified; and the evolution of tenure to natural resources to be assessed.

Although a large theoretical literature discusses the possible inefficiency of sharecropping contracts, empirical evidence on this phenomenon has been ambiguous at best. Household level fixed-effect estimates from about 8,500 plots operated by households who own and sharecrop land in the Ethiopian highlands provide support for the hypothesis of Marshallian inefficiency. At the same time, a factor adjustment model suggests that the extent to which rental markets allow households to attain their desired operational holding size is extremely limited.

There is widespread agreement on the need for land reform in Zimbabwe as a means ofreducing poverty. This paper assesses the potential consequences of a land-reformscheme that draws on proposals from Zimbabwe’s government in 1998 and 1999. Weanalyze the impact of the reform on resettled farm households and as a developmentproject for which we conduct cost-benefit analysis. The analysis, which considers costsand benefits during a 15-year period, relies on a set of models of family farms that aretypical of those that would benefit from land redistribution.
