Originally published in 1985, this book argues forcefully and practically for new relationship between science and the small farmer. It advocates scientific research seeking out changes which are already taking place within the smallholder farming sector and building on local initiatives. Drawing on his experience of West Africa, the author demonstrates that many of the most successful innovations in food-crop production during the 20^th century have indigenous roots and that there should therefore be less emphasis on ‘teaching’ farmers how to farm and more emphasis on how to foster and support local adaptation and inventiveness. This book will be of interest to students of agriculture, environmental studies and rural development as well as those working with relief and development agencies.
