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.
Download or read book Soil and Soil Fertility Management Research in Sub Saharan Africa written by Henk Mutsaers and published by Taylor & Francis. This book was released on 2017-03-27 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Judicious soil fertility management is crucial for sustainable crop production and food security in sub-Saharan Africa (SSA). This book describes the various concepts and approaches underlying soil and soil fertility management research in SSA over the last fifty years. It provides examples of important innovations generated and assesses the position of research within the research-to-development continuum, including how innovations have been validated with the intended beneficiaries. Using the experience of the International Institute of Tropical Agriculture (IITA) as a case study, the authors analyse how processes, partnerships and other factors have affected research priorities, the delivery of outputs, and their uptake by farming communities in SSA. They evaluate both successes and failures of past investments in soil fertility research and important lessons learnt which provide crucial information for national and international scientists currently engaged in this research area. The book is organised in a number of chapters each covering a chronological period characterised by its primary research content and approaches and by the dominant research paradigms and delivery models.
Download or read book Improving Soil Fertility Recommendations in Africa using the Decision Support System for Agrotechnology Transfer DSSAT written by Job Kihara and published by Springer Science & Business Media. This book was released on 2012-03-12 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book gives a detailed description of the application of DSSAT in simulating crop and soil processes within various Agro-ecological zones in Africa. The book, an output of a series of 3 workshops, provides examples of the application of DSSAT models to simulate nitrogen applications, soil and water conservation practices including effects of zai technology, phosphorus and maize productivity, generation of genetic coefficients, long-term soil fertility management technologies in the drylands, microdosing, optimization of nitrogen x germplasms x water, spatial analysis of water and nutrient use efficiencies and, tradeoff analysis. The minimum dataset requirements for DSSAT is discussed. This book arises from attempts to address the limited use of models in decision support by African agricultural (both soil scientist and agronomists) scientists.
Download or read book Fertility of Soils written by Christian J.M.G. Pieri and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can a continuous growth of agriculture be achieved in the sub-Sahara region without inducing irreversible damage to the ecosystem? Until now, doubts have been expressed as to the actual capacity of the soils to sustain a desirable increase of production which can match the requirements of a fast-growing population. Thirty years of investigation and a renewed comprehensive interpretation of research data on soil fertility show that a sustainable agriculture growth could be a practical possibility in a savannah region.

M., Budaza, N., Mavundla, S., Nohayi, N.N., Nortje, K., Boroto, R.J. and published by Food & Agriculture Org.. This book was released on 2021-10-27 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is a major challenge for life on Earth. It is mainly manifested through modifications of average temperature, rainfall intensity and patterns, winds and solar radiation. These modifications significantly affect basic resources, such as land and water resources. Populations at disproportionately higher risk of adverse consequences with global warming of 1.5°C and beyond include disadvantaged and vulnerable populations, some indigenous peoples, and local communities dependent on agricultural or coastal livelihoods (IPCC, 2018). Therefore, adaptation measures are recommended in order to cope with climate change. Indigenous peoples have developed practices for climate change adaptation, based on their long-term experience with adverse climatic effects. There was thus a need to identify such practices as they could be effectively mainstreamed in community-based adaptation programmes. This report makes an inventory of indigenous and community adaptation practices across the world. The inventory was mainly done through literature review, field work and meetings with selected organisations. The case studies documented are categorized in five technologies and practices themes, including: (1) Weather forecasting and early warning systems; (2) Grazing and Livestock management; (3) Soil and Water Management (including cross slope barriers); (4) Water harvesting (and storage practices); (5) Forest Management (as a coping strategy to water scarcity), and; (6) Integrated wetlands and fisheries management. These were then related to the corresponding main agro-ecological zones (AEZ), namely arid, semi-arid, sub-humid, humid, highlands and coastal and wetlands. The AEZ approach was considered as an entry-point to adopting or adapting an existing indigenous strategy to similar areas. Challenges that threaten the effectiveness of indigenous and community adaption strategies were identified. These challenges include climate change itself (which is affecting the indicators and resources used by communities), human and livestock population growth (which is increasing pressure on natural resources beyond their resilience thresholds), current institutional and political settings (which limit migrants’ movements and delimits pieces of usable land per household), cultural considerations of communities (such as taboos and spiritual beliefs), and the lack of knowledge transfer to younger communities. Indigenous knowledge provides a crucial foundation for community-based adaptation strategies that sustain the resilience of social-ecological systems at the interconnected local, regional and global scales. In spite of challenges and knowledge gaps, these strategies have the potential of being strengthened through the adoption and adaptation of introduced technology from other communities or modern science. Attention to these strategies is already being paid by several donor-funded organisations, although in an uncoordinated manner.

Download or read book Fighting Poverty in Sub Saharan Africa The Multiple Roles of Legumes in Integrated Soil Fertility Management written by Andre Bationo and published by Springer Science & Business Media. This book was released on 2011-08-24 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legumes play an important role in the cropping systems of sub Saharan Africa (SSA). Legumes are an important source of nutrition to both humans and livestock by providing the much needed protein, minerals, fibre and vitamins. The sale of legumes seed, leaves and fibre generates income for the marginalized communities especially women. Cultivation of legumes is essential for the regeneration of nutrient-deficient soils. By biologically fixing nitrogen (BNF) in the soil, legumes provide a relatively low-cost method of replacing otherwise expensive inorganic nitrogen in the soil. This enhances soil fertility and boosts subsequent cereal crop yields. Production of legumes in SSA is however; hampered by a number of constraints among them low and declining soil fertility, low soil pH, high salinity, drought and flooding, poor access to improved germplasm, diseases, pests and weeds. Farmers need to learn how to overcome these constraints if the full benefits of legumes are to be gained. This book presents a synthesis of research work on legumes and draws attention to the importance of legumes in integrated soil fertility management (ISFM) and poverty alleviation in SSA.

Book excerpt: Soils are critical to agriculture and, in turn, to food supply and livelihoods. Sustainable management of soils is crucial for a large proportion of the population of Africa. Contrary to many claims, soil fertility is improved and managed successfully by small-scale farmers there. Careful studies from widely different areas reveal how closely bound up soil management is with complex social, cultural and ecological factors - requiring a far more subtly tuned approach to development policy and practice. This work is a study of how the context of livelihood systems has to inform development policy and practice.
