This study was conducted with the main objective of determining the linkages between poverty and land management practices in Uganda. The study used the 2002/03 Uganda National Household Survey (UNHS) and more focused data collected from a sub-sample of 851 households of the 2002/03 UNHS sample households. We found that farmers in Uganda deplete about 1.2 percent of the nutrient stock stored in the topsoil per year, which leads to a predicted 0.31 percent reduction in crop productivity.

We investigate the impacts of sustainable land management practices on soil carbon stocks and also impacts of soil carbon on the mean and variance of crop production using econometric tools. Using a cross-sectional plot-level dataset collected from three agroecological zones of Uganda with soil carbon measured at a depth of 0 to 15 centimeters, our results have robustly shown that irrigation, fertilizers, improved fallow, crop residues, mulching, and trash lines are positively and significantly associated with higher soil carbon, corroborating results from agronomic experiments.

Abstract

Ethiopia is one of the poorest countries in the world, and its population of more than 70 million people lives mostly in the highlands. The food security of these people is threatened by land degradation and droughts that cause declining and highly variable land productivity. Changes in the global climate may also have caused an increase in the incidence of drought that has occurred recently in areas that were not affected by the earlier droughts.

A farmer-managed, agroenvironmental transformation has occurred over the past three decades in the West African Sahel, enabling both land rehabilitation and agricultural intensification to support a dense and growing population. This paper traces the technical and institutional innovations, their impacts, and lessons learned from two successful examples. The first is the story of the improvement and replication of indigenous soil and water conservation practices across the Central Plateau of Burkina Faso.

This study compares the impacts of integrated soil fertility management (ISFM) on crop production with use of either mineral fertilizer or organic manure alone. We also investigate the conditions under which .ISFM technology has greater beneficial effects on yields and the factors constraining its uptake. To answer these questions, the study uses a cross-sectional, plot-level data set collected in Nigeria by the International Food Policy Research Institute and the World Bank in 2009.

Les nouvelles sur l’état de l’agriculture en Afrique sont en grande partie décourageantes, mais on entrevoit des lueurs d'espoir. Quelques efforts stimulants réalisés par des agriculteurs et chercheurs africains au cours des dix dernières années ont sensiblement augmenté la productivité agricole dans certains pays et pour certains produits. Ces cas peuvent servir de modèles pour de futurs efforts, mais seulement si les responsables des politiques de développement et les professionnels comprennent les processus qui ont amené ces résultats, et les éléments clé de leur succès.

Under the regimes of Idi Amin (1971–79) and Milton Obote (1980–85), Uganda’s economy plunged into a prolonged crisis with negative real growth rates of GDP (Baffoe 2000). In 1987, under Yoweri Musevini, the Ugandan government introduced an economic recovery program in cooperation with the IMF and the World Bank, aiming at market liberalization, privatization, and de-centralization.

Many countries in Sub-Saharan Africa suffer from problems related to poverty, natural resource degradation, and the complex interactions between these phenomena (Cleaver and Schreiber 1994). In the northern Ethiopian highlands of Tigray region, problems of poverty and degradation are extremely severe: population density is very high, rainfall is scarce and erratic, and soil fertility is low. Under such conditions, farmers need to rely on external inputs and soil conservation practices in order to stabilize or increase yields.

This chapter focuses on the management of agricultural land by smallholder households in the highlands of Kenya. It draws mainly from several recent studies from the central highland areas near to the south and west of Mt. Kenya and the western highland areas to the north and west of Kisumu, which were led by the authors. The chapter also draws from a set of studies under the KAMPAP project.1 See the appendix for a description of the key papers used in this synthesis.

This paper examines the nature of community management of woodlots and investigates the determinants of collective action and its effectiveness in managing woodlots, based on a survey of 100 villages in Tigray, northern Ethiopia. We find that collective management of woodlots generally functions well in Tigray. Despite limited current benefits received by community members, the woodlots contribute substantially to community wealth, increasing members’ willingness to provide collective effort to manage the woodlots.
