(English Abstract) |
The objective of this paper is to determine vulnerable area to deforestation. The Gunung Mutis Nature Reserve (GMNR), located in Eastern of Indonesia was selected as study area. The combination of Multi Criteria Evaluation (MCE) method and Geographic Information System (GIS) spatial analysis were used to produce map of vulnerability area to deforestation. The main data used were data from interview with the GMNR management and information from experts related to area that vulnerable and susceptible to deforestation. Based on those data, three criteria were defined namely, accessibility (distance from settlement and slope), safe from forest ranger (distance from road and view shed) and close to existing agriculture (distance to existing agriculture). Scores based on their vulnerability to deforestation were given on each of the criteria. The lowest score represented the area that was not vulnerable and the highest score represented the area that vulnerable to deforestation. After scoring, weighting process was applied by giving the ranking on each criterion based on their importance. And the final process on second step was weighting overlay to produce map of vulnerability area to deforestation. The result showed that approximately 66% of GMNR areas were not/low vulnerable and 34% of the GMNR areas were classified as moderate/high vulnerable areas to deforestation.
