"This book attempts to summarize the experiences of farmers, researchers, and development workers, and policy and decision-makers who have interacted with AHI on the theme of Integrated Natural Resource Management in the humid highlands of eastern Africa. It aims both to raise awareness of the crucial importance of methods or “approaches” in the outcomes derived from research and development work, and to distill lessons learned on “what works, where, and why.” The book therefore is enriched with examples and case studies from five benchmark sites whose variability provides the reader with an in-depth knowledge of the complexities of natural resource management (NRM) in agro-ecosystems that play an important role in the rural economy of the region. The struggle to achieve sustainable agricultural development in challenging environments is a difficult one, and can only be effectively achieved through combined efforts and commitment of individuals and institutions with complementary roles."
