Crop-livestock Interaction in Sub-Sarahan AfricaWorld Bank, 1992 - 246 pages This book is the result of a collaborative research effort between the World Bank and the International Livestock Centre for Africa. It extends previous work on agricultural mechanization and the evolution of farming systems in Africa by seeking to answer a number of basic questions about the integration of crops and livestock in sub - Saharan Africa. Those questions include the role of mixed farming in promoting agricultural growth, the appropriate points at which to encourage the use of animals as sources of farm power, the contribution of animals to improving the poor fertility of African soils, the efficacy of different methods to better livestock nutrition, and the economic returns to incorporating livestock production on small farms. While many individual studies have analyzed such issues in the past, this book is the first comprehensive review of existing knowledge which offers general explanations of crop-livestock relations with respect to both economic and technical features of African agriculture. In doing so, experimental evidence is carefully synthesized and examined in light of field visits to thirty-three different sites through the major agroclimates of sub - Saharan Africa. The detailed empirical nature of the book permits specific conclusions to be drawn for different farming systems, while its comparisons across those systems allow broad explanations of contrasting crop-livestock interactions. |
