This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Africa escaped from the glaciers that covered the temperate parts of the world during the Ice Age. The legacy is that most of the parent materials of the soils of tropical Africa are old, highly weathered and devoid of bases and phosphate-bearing minerals. Traditional farming systems which were relatively stable and sustainable relied on long fallow periods after one to two years of cropping to maintain the productive capacity of the soils. In recent times and especially in densely populated areas, a sizeable class of 'landless' farmers have begun to cultivate marginal lands or to invade the 'forest reserves' thereby exacerbating the problems of land and environ mental degradation. of soil fertility that will facilitate the production of adequate quantities of the principle Maintaining a level staples has become a major challenge to agricultural scientists in tropical Africa. To increase the nutrient supplying power of soils requires the inputs of fertilizers. These can be organic or inorganic. The efficiency with which these externally supplied inputs can increase agricultural production and reduce soil and environmental deterioration is dependent on the ability of scientists to determine the right types and quantities of the products to apply to each soil, crop and cropping system as well as the ability of farmers to acquire requisite farm manage ment skills.

Book excerpt: In Burkina Faso, where 90% of the population depends upon subsistence agriculture for its livelihood, both the amount and distribution of rainfall during the growing season markedly determine the agricultural productivity. In this study, the temporal variability in rainfall over Burkina Faso is described at different scales: annual, seasonal, monthly, and decadal. Rainfall dependability is explained using probability analysis of decadal totais. Monthly means of maximum and minimum air temperature are used to compute the probabilities of temperature exceeding defined threshold levels. Simple water balance models are used to describe the variation in available soil-moisture storage and water-availability periods for different locations. Applications of the analysis of climatic data in crop planning are presented.

Book Synopsis Improved Crop Productivity for Africa’s Drylands by : Tom Walker
Download or read book Improved Crop Productivity for Africa’s Drylands written by Tom Walker and published by World Bank Publications. This book was released on 2016-08-17 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
