Land Use, Nature Conservation and the Stability of Rainforest Margins in Southeast Asia

The stability of rainforest margins has been identified as a critical factor in the preservation of tropical forests, e.g., in Southeast Asia, one of the world's most extensive rainforest regions. This book contains a selection of contributions presented at an international symposium on "Land Use, Nature Conservation and the Stability of Rainforest Margins in Southeast Asia," in Bogor, Indonesia, October 2002. It highlights the critical issue of rainforest preservation from an interdisciplinary perspective, comprising input from scientists in socio-economic, biological, geographical, agrarian and forestry disciplines. The contributions are based on recent empirical research, with a special focus on Indonesia - a country with one of the highest and, at the same time, most endangered stocks of rainforest resources on earth.

Southeast Asia constitutes one of the world's most extended rainforest regions. It is characterized by a high degree of biodiversity and contains a large variety of endemic species. Moreover, these forests provide a number of important and sin­ gular ecosystem services, like erosion protection and provision of high quality wa­ ter, which cannot be replaced by alternative ecosystems. However, various forms of encroachment, mostly those made by human interventions, seriously threaten the continuance of rainforests in this area. There is ample evidence that the rainforest resources, apart from large scale commercial logging, are exposed to danger particularly from its margin areas. These areas, which are characterized by intensive man-nature interaction, have been identified as extremely fragile systems. The dynamic equilibrium that bal­ ances human needs and interventions on the one hand, and natural regeneration capacity on the other, is at stake. The decrease of rainforest resources is, to a sub­ stantial degree, connected with the destabilization of these systems. Accordingly, the search for measures and processes, which prevent destabilization and promote stability is regarded as imperative. This refers to both the human and the natural part of the forest margin ecosystem.
