The Roots of Change focuses attention on the source of local agrarian change: human creativity and social interaction. Building on the view that these innate human characteristics are central forces in the evolution of local agricultural systems, this volume explores the patterns of farmers' individual and joint behavior in the generation, adaptation, and spread of new agricultural practices. As well as identifying ways of liberating the creative potential of farmers, field workers and researchers, the study also provides a detailed examination of what, why and how changes have taken place in the farming systems of Southwestern Mali, and how the indigenous processes involved have interacted with various external research and development efforts.
