This study examines the current and potential role of economics in soil productivity in sub-Saharan Africa. After examining the status of soil productivity and the contribution of conventional economic analyses, it considers more innovative approaches that enable economics to play a greater role in the planning and evaluation of soil productivity, enhancing measures at farm, national and global level. In the past economics has tended to focus on one factor at a time but many factors affect soil productivity. Decisions, policies and their impact call for a more integrative, participatory analytical approaches capable of weighing various aspects simultaneously. This study highlights how economics can respond to this challenge through the a[application of fresh concepts (e.g. natural capital) and specific techniques (e.g. multi-criteria analysis, green accounting).

This publication reviews issues related to land degradation, with focus on problems of soil fertility management in sub-Saharan Africa. It highlights some successful experiences in the region, constraints and possible solutions specific to the major agro-ecological zones and the importance of the holistic and participatory approaches for soil productivity improvement. The need for action and collaborative efforts of all stakeholders, within the framework of ongoing initiatives, are emphasized. It is hoped that this document will contribute to increase awareness of senior specialists and policy-makers about the problems and alternative solutions towards enhanced and sustained soil productivity.

This strategy is evaluated using field studies and modeling from the major agroecological zones of crop production. The authors address the higher-input, yield-increasing strategy from the perspective of risk, sustainability and the impact on women. They also consider alternative approaches to increasing output through area expansion and livestock-crop integrated systems.

Agricultural Investment and Productivity provides a deep and systematic look at the opportunities for and constraints to investments in sustainable agriculture in East Africa, offering important insights into what works and how to analyze agricultural investments in one of the poorest regions of the world. The book critically examines the reasons behind East Africa's stagnant agricultural productivity over the past forty-five years, using the primary lens of investments in fertilizers, seeds, and sustainable land management technologies, These investments have a tremendous impact on production volume, ultimately affecting the income of millions of families throughout the region.

World Bank Technical Paper No. 408. This report is a critical review of the technical, economic, and institutional constraints on improving soil fertility in Sub-Saharan Africa, and the actions recommended to address them. Action plans prepared for Ghana, Kenya, Malawi, and Mali examine the demand for and supply of mineral fertilizers, the exploitation of local mineral resources, the prevention of soil erosion and increasing soil-water retention, and soil fertility management using organic technologies and management practices.

More than 200 million people living in dryland regions of Sub-Saharan Africa make their living from agriculture. Most are exposed to weather shocks, especially drought, that can decimate their incomes, destroy their assets, and plunge them into a poverty trap from which it is diffi cult to emerge. Their lack of resilience in the face of these shocks can be attributed in large part to the poor performance of agriculture on which their livelihood depends. Opportunities exist to improve the fortunes of farming households in the drylands. Improved farming technologies that can increase and stabilize the production of millet, sorghum, maize, and other leading staples are available. Irrigation is technically and economically feasible in some areas and offers additional opportunities to increase and stabilize crop production, especially small-scale irrigation, which tends to be more affordable and easier to manage. Yet many of these opportunities have not been exploited on a large scale, for reasons that include lack of farmer knowledge, nonavailability of inputs, unfavorable price incentives, high levels of production risk, and high cost. Future production growth in drylands agriculture is expected to come mainly from raising yields and increasing the number of crop rotations on land that is already being cultivated (intensifi cation), rather than from bringing new land into cultivation (extensifi cation). Controlling for rainfall, average yields in rainfed cropping systems in Sub-Saharan Africa are still much lower than yields in rainfed cropping systems in other regions, suggesting that there is considerable scope to intensify production in these systems. Furthermore, unlike in other regions, production of low-value cereals under irrigation is generally not economic in Sub-Saharan Africa unless the cereals can be grown in rotation with one or more high-value cash crops. The long-run strategy for drylands agriculture, therefore, must be to promote production of staples in rainfed systems and production of high-value cereals (for example, rice), horticultural cops, and industrial crops in irrigated systems. Based on a detailed review of currently available technologies, Improved Crop Productivity for Africa’s Drylands argues that improving the productivity and stability of agriculture in the drylands has the potential to make a signifi cant contribution to reducing vulnerability and increasing resilience. At the same time, it is important to keep in mind that in an environment characterized by limited agro-climatic potential and subject to repeated shocks, farming on small land holdings may not generate suffi cient income to bring people out of poverty.
