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