Abstract:This article evaluates the environmental impact of shifting cultivation in the tropical rain forest, based on fieldwork among the Bongando people in Yalisanga village, Equateur Region, central Zaire, over three periods in 1986-1989, supplemented by data from remote sensing, a land use map by pace measuring and soil sampling. In order to examine the sustainability of Bongando shifting cultivation the author analysed the extent of primary forest being destroyed under the Bongando cultivation system and the extent of soil deterioration occurring in the Bongando fields. He found that the cultivation-fallow cycle is not completed in the secondary forest. Newly cleared fields are gradually intruding into the surrounding primary forest. The previously balanced relationship between humans and the forest has been upset as a result of sedentarization, population growth and the introduction of coffee as a cash crop with the penetration of the market economy. On the other hand, however, it seems that the field soil is not extremely depleted by cultivation since there is no clearly detectible difference in soil fertility between forest and field. This suggests that by taking appropriate measures, such as periodical village movement, tropical rain forest and its soil might be used continuously. Bibliogr., notes, sum.
