"Low external-input technology (or LEIT) is an increasingly prominent subject in discussions of sustainable agriculture. This book examines the contributions and limitations of LEIT for addressing the needs of resource-poor farmers. For the first time a balanced analysis of LEIT is provided, offering in-depth case studies, an analysis of the debates, an extensive review of the literature and practical suggestions about the management and integration of low external-input agriculture in rural development programmes."--BOOK JACKET.
