This book presents a collection of innovative, successful and diverse approaches to agricultural development. Documented in 12 case studies, these approaches draw upon greater knowledge, skill and labour input, rather than on larger, unsustainable capital expenditure, and are shown to increase yields substantially. Part 1 of the book (chapters 1-6) deals with issues for analysis and evaluation concerning sustainable agricultural development. Part 2 (chapters 7-18) presents the case studies from Africa, Latin America, and Asia. Part 3 (chapters 19-22) focuses on advancing agroecological agriculture with participatory approaches. The book has a subject index.
