Shifting cultivation is the predominant system of arable farming in the humid and sub-humid tropics, where several hundred million people depend on this system of agriculture for their livelihood. This book documents and systematizes findings in shifting cultivation from over the last six decades, including characterizing secondary succession and relating the changes that fallow vegetation undergoes to the process of soil fertility restoration. This book is essential reading for researchers and students of tropical agriculture and related areas.

Shifting cultivation is one of the oldest forms of subsistence agriculture and is still practised by millions of poor people in the tropics. Typically it involves clearing land (often forest) for the growing of crops for a few years, and then moving on to new sites, leaving the earlier ground fallow to regain its soil fertility. This book brings together the best of science and farmer experimentation, vividly illustrating the enormous diversity of shifting cultivation systems as well as the power of human ingenuity. Some critics have tended to disparage shifting cultivation (sometimes called 'swidden cultivation' or 'slash-and-burn agriculture') as unsustainable due to its supposed role in deforestation and land degradation. However, the book shows that such indigenous practices, as they have evolved over time, can be highly adaptive to land and ecology. In contrast, 'scientific' agricultural solutions imposed from outside can be far more damaging to the environment and local communities. The book focuses on successful agricultural strategies of upland farmers, particularly in south and south-east Asia, and presents over 50 contributions by scholars from around the world and from various disciplines, including agricultural economics, ecology and anthropology. It is a sequel to the much praised "Voices from the Forest: Integrating Indigenous Knowledge into Sustainable Upland Farming" (RFF Press, 2007), but all chapters are completely new and there is a greater emphasis on the contemporary challenges of climate change and biodiversity conservation.

Shifting cultivation supports around 200 million people in the Asia-Pacific region alone. It is often regarded as a primitive and inefficient form of agriculture that destroys forests, causes soil erosion and robs lowland areas of water. These misconceptions and their policy implications need to be challenged. Swidden farming could support carbon sequestration and conservation of land, biodiversity and cultural heritage. This comprehensive analysis of past and present policy highlights successes and failures and emphasizes the importance of getting it right for the future. This book is enhanced with supplementary resources. The addendum chapters can be found at: www.cabi.org/openresources/91797
