Available in PDF, EPUB and Kindle. Book excerpt: The most traditional and widely used farming systems in the humid upland tropics are based on fallowing and various forms of slash and burn agriculture. Their sustainability depends on the duration of the fallow. When fallow duration drops below the threshold of seven or eight years crop yield usually declines. A concept described as "forest rent". Given the plight of millions of farmers the development of upland agriculture has become increasingly important. This book reports the results of fieldwork conducted by the editors and other experts in some 40 regions of Indonesia from 1989 to 2001. It finds that some of the most successful improvements have been the result of innovations by the farmers themselves.
