Farming Systems of the African Savanna: A continent in crisis
Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.
In addition, although use of animal health services, and adoption of improved livestock breeds and modern management practices have increased, ownership of various types of livestock has declined.
Commercial channels for wool, fibres and pelts have developed more slowly in the transition period, although commercial demand is now causing a partial revival in the industry.
With accelerating urbanization and growing inter-dependence of rural and urban dwellers on the markets and resources they each offer, rural urban linkages have become a very important focus in recent years for research and policy relating to local and national economic development, poverty reduction and governance. The emergence of new livelihoods based on diversified income sources and mobility reflects profound social, cultural and economic transformations, and new forms of resource allocation and use. This volume collects the key contributions in the field, covering the conceptual background, the key issues and the current debates, locating different approaches in their wider intellectual and historical contexts. It also includes important recent empirical work from all the relevant geographical regions that that will be the basis for future thinking. Fifteen papers are clearly organized around the principal themes and accompanied by a valuable editorial introduction clearly setting out the issues, the arguments and the evidence. Suggestions for further reading and additional information sources are also included. Published with IIED.
Soil degradation and nutrient depletion have become serious threats to agricultural productivity in Africa. Soils cannot supply the quantities of nutrients required and yield levels decline rapidly once cropping commences. This book addresses these issues and includes papers from an international symposium held at Cotonou, Benin, October 9-12, 2000, organized by the International Institute of Tropical Agriculture, Ibadan, Nigeria and the Department of Land Management of the Katholieke Universiteit Leuven, Belgium. In five main parts it marks the end of a first phase of collaborative research on "Balanced Nutrient Management Systems for the Moist Savanna and Humid Forest Zones of Africa" and concludes with recommendations, providing essential reading for crop and soil scientists.
