This book presents an important discussion on future options for sustainable soil management in Africa from various perspectives, including national soil protection regulations, the role of tenure rights, the work of relevant international institutions such as the UNCCD and FAO, and regional and international cooperation. This first volume of the new subseries Regional Perspectives to the International Yearbook of Soil Law and Policy includes contributions by African and international experts alike. Given the range of key topics covered, the book offers an indispensable tool for all academics, legislators and policymakers working in this field. The “International Yearbook of Soil Law and Policy – Regional Perspectives” series discusses central questions in law and politics that concern the protection and sustainable management of soil and land in different regions of the world.

Soils of South Africa is the first book in seventy years that provides a comprehensive account of South African soils. The book arranges more than seventy soil forms into fourteen groups and then provides, for each group: • maps showing their distribution and abundance throughout South Africa • descriptions of morphological, chemical and physical properties • a detailed account of classification and its correlation with international systems • a discussion of soil genesis which includes a review of relevant research papers • appraisal of soil quality from a land use perspective as well as for its ecological significance • illustrative examples of soil profiles with analytical data and accompanying interpretations. There is also a fascinating account of the special relationship that exists between South African animals and soil environments. Soils of South Africa should interest students and researchers in the earth, environmental and biological sciences, as well as environmental practitioners, farmers, foresters and civil engineers.

Indigenous soil and water conservation practices are rarely acknowledged in the design of conventional development projects. Instead, the history of soil and water conservation in Africa has been one of imposing external solutions without regard for local practice. There is a remarkably diverse range of locally developed and adapted technologies for the conservation of water and soil, well suited to their particular site and socio-economic conditions. But such measures have been ignored, and sometimes even overturned, by external solutions. Sustaining the Soil documents farmers' practices, exploring the origins and adaptations carried out by farmers over generations, in response to changing circumstances. Through a comparative analysis of conservation measures - from the humid zones of West Africa to the arid lands of the Sudan, from rock terraces in Morocco to the grass strips of Swaziland - the book explores the various factors that influence adoption and adaptation; farmers' perceptions of conservation needs; and the institutional and policy settings most favorable to more effective land husbandry. For the first time on an Africa-wide scale, this book shows that indigenous techniques work, and are being used successfully to conserve and harvest soil and water. These insights combine to suggest new ways forward for governments and agencies attempting to support sustainable land management in Africa, involving a fusion of traditional and modern approaches, which makes the most of both the new and the old.

Land degradation from soil erosion has been considered by many to be a problem of significant proportion, affecting some 30-50% of the earth's land surface. At the time of the first publication of this book in 1993, estimates indicated that 10-15 million hectares of land were being lost each year through erosion and salinisation from irrigation and that at such a rate of loss, topsoil reserves on most sloping lands would be depleted within two hundred years. Since humankind's dependency on the land for food is almost total, soil erosion represents a real threat to the security of our food supply. The need for the immediate conservation of the world's soil resources is therefore clear. As part of the response to this need, the International Union for the Conservation of Nature's Commission on Ecology convened a special working group to consider the problem of world soil erosion and to propose practical solutions for soil conservation. This important book presents the outcome of their work.

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.

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.
