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.

Norman Borlaug and his colleagues, when developing the Asian Green Revolution, did not have an organization behind them like the Alliance for a Green Revolution in Africa (AGRA). Its founding 10 years ago was a smart thing to do. H. E. Kofi Annan sounded the call for a uniquely African Green Revolution on July 5, 2004, at a meeting of Heads of State in Addis Ababa, Ethiopia. Not long afterwards, AGRA was established. Given the complexity of the challenges involved, AGRA had to be invented from scratch because no such institution existed before.At its start, AGRA focused on four main components of what a Green Revolution needed most: seeds, soils, markets and policy. How to overcome nutrient depletion and soil compaction so common in most smallholder farms of sub-Saharan Africa is a major challenge in itself ¿ not something that the Asian Green Revolution had to face. African soils are now unhealthy and this has been directly related to unhealthy people. And largely because of that, cereal yields in sub-Saharan Africa hovered around 1 MT/ha, the lowest of any region of the world. AGRA has stimulated what is now an organic movement composed of farmers,farmer associations, NGOs, policymakers, scientists and advocates from the private and public sectors throughout Africa and beyond.AGRA¿s Soil Health Program (SHP) started with a bang at the Africa Fertilizer Summit held in Abuja in June, 2006. This gathering created awareness of the need for increased use of mineral fertilizers (from about 8 kg/ha to 50 kg/ha) as the key vehicle for overcoming soil fertility depletion. Commitments made at the Summit and follow-up actions resulted in the average fertilizer use in Africa increasing from 8 kg of actual NPK fertilizers per hectare at that time to the current level of 16 kg/ha, a good first step. Several of us soil scientists attending the Summit felt that, for the first time, people were listening to us.

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.

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.

This book is about the main lessons to be learnt from new approaches to soil and water conservation in sub-Saharan Africa. It presents six case studies, two each from Burkina Faso, Kenya and Mali, where soil and water conservation, based on the participation of the local people, has resulted in some success.
