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.

Download or read book Biodiversity of West African Forests written by L. Poorter and published by CABI. This book was released on 2004 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rain forests of West Africa have been designated as one of the world's hotspots of biodiversity. They extend from Ghana to Senegal and are referred to as the Upper Guinean forests. Because of their isolated position, they harbour a large number of rare and endemic animal and plant species.This book focuses on the biodiversity and ecology of these forests. It analyses the factors that give rise to biodiversity and structure tropical plant communities. It also includes an atlas with ecological profiles of rare plant species and large timber species.
Download or read book Soil Quality and Agricultural Sustainability written by R. Lal and published by CRC Press. This book was released on 1998-11-01 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil degradation causes a shrinking of arable land resources, and the persistence of starvation and malnutrition. The depletion is compounded by the increasing populations of developing tropical nations, and the conversion of agricultural land to other uses. As a result, per capita grain harvesting and irrigated land is in steady decline all over the world. The decrease in horticultural resources and productivity has inspired Soil Quality and Agricultural Sustainability, which is based primarily on papers presented at the 1996 conference on soil degradation, sponsored by Ohio State University, the USAID and the International Agricultural Research Centers. The book addresses itself to six concerns: basic concepts and global issues, nutrient and water inputs, soil quality management in Asia, in Africa, and in the Tropical Americas, and future priorities. The Editor's goal is a new paradigm in soil quality research: a multidisciplinary approach. He proposes that an erosion management program include soil scientists, hydrologists, climatologists, sedimentologists, geographers, agronomists, agricultural engineers, land use planners, economists, anthropologists and social scientists. Lal advocates an optimistic, forward-thinking brand of soil science that concentrates on conservation and fertility. The 26 chapters explore what Lal considers to be the priorities: agricultural sustainability, soil quality, food security, quality restoration, long-term management, and the failure to adopt new technology. In sum, they paint a comprehensive portrait of the current state, and future prospects, for worldwide agronomic viability.
Download or read book Soil and Soil Fertility Management Research in Sub Saharan Africa written by Henk Mutsaers and published by Routledge. This book was released on 2017-03-27 with total page 390 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.

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 A Ritual Geology written by Robyn d'Avignon and published by Duke University Press. This book was released on 2022-07-11 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Set against the ongoing corporate enclosure of West Africa’s goldfields, A Ritual Geology tells the untold history of one of the world’s oldest indigenous gold mining industries: Francophone West Africa’s orpaillage. Establishing African miners as producers of subterranean knowledge, Robyn d’Avignon uncovers a dynamic “ritual geology” of techniques and cosmological engagements with the earth developed by agrarian residents of gold-bearing rocks in savanna West Africa. Colonial and corporate exploration geology in the region was built upon the ritual knowledge, gold discoveries, and skilled labor of African miners even as states racialized African mining as archaic, criminal, and pagan. Spanning the medieval and imperial past to the postcolonial present, d’Avignon weaves together long-term ethnographic and oral historical work in southeastern Senegal with archival and archeological evidence from Burkina Faso, Côte d’Ivoire, Guinea, and Mali. A Ritual Geology introduces transnational geological formations as a new regional framework for African studies, environmental history, and anthropology.
