Mountain Ecosystem Assessment based on Ecosystem Services and Human Activities: A Case in Upper Part of Bogowonto Watershed, Indonesia

Abstract

Mountain ecosystem management in Indonesia especially in Java, has not well prepared by pre-assessment of the actual potential of ecosystem. The varied components in mountain ecosystem create complex problems in making an ideal decision. This research aimed to identify the relationship between ecosystem services value and human activities in mountain ecosystem as well as to agglomerate the areas which have similar characteristics by using clustering system. The research was conducted in upper part of Bogowonto watershed on Mt. Sumbing, Central Java. This was carried-out by assessing the biotic & the abiotic components, as well as the human activities at the village level. The biotic and abiotic components were valued in Indonesian currencies (Rupiah), meanwhile the human activities were valued by indexes. The Hierarchical Cluster Analysis was used to classify these criteria. This method enables variables, such as Net Primary Production (NPP), water value, and human activity index, to be grouped based on the similarities in criteria. By designing cluster, the pattern of correlation between human activity indexes and ecosystem services value can be depicted. In brief, an inversely proportional relationship between human activity and services value of biotic and abiotic components could be showed.
