The plight offorest-living peoples has become an international issue; concerns over the greenhouse effect and other climatic changes are often linked to rain forest destruction. At the same time, there has been an unparalleled scientific interest in the workings ofthe rain forest and an increasingconcern by economists as to its potential in balancing the books of many developing countries. The need for an advanced yet concise and up-to-date synthesis ofrecent studies and a key to the increasingly voluminous literature on rain forests is even greater than it was in 1983.
