Abstract

Forest and land fires represent a form of environmental disaster resulting from the interaction between natural factors and human activities in land use. Ngawi Regency, which is spatially dominated by agricultural and forested areas, exhibits biophysical and socio-environmental characteristics that may increase its vulnerability to forest and land fires. This study aims to assess the level of forest and land fire vulnerability in Ngawi Regency using a descriptive quantitative approach based on Geographic Information Systems (GIS). The analysis was conducted through scoring, spatial overlay, and vulnerability classification using the Equal Interval method applied to a set of biophysical and anthropogenic parameters. The results indicate that the study area is predominantly characterized by a moderate level of vulnerability, while areas with high and low vulnerability are more limited and spatially concentrated. The spatial pattern of vulnerability reveals a strong relationship between physical environmental conditions and the intensity of human activities. Areas located near settlements and road networks tend to exhibit higher vulnerability levels compared to areas with lower human influence. These findings highlight the importance of forest and land fire vulnerability mapping as a supporting tool for more targeted, adaptive, and sustainable mitigation planning aimed at reducing fire risk at the regional level.

Abstract

Karangpandan District is one of the districts in Karanganyar Regency that experiences a high incidence of landslides, this is influenced by its location in the transition zone between the lowlands and the foothills of Mount Lawu, causing Karangpandan District to have a varied topography. This study aims to analyze the level of exposure of residents in Karangpandan District to landslide hazard zones according to Karanganyar Regent Regulation Number 83 of 2022 and determine landslide disaster evacuation routes in Karangpandan District as part of disaster mitigation. This study was conducted using a spatial approach, using scoring analysis for the level of population exposure and network analysis to determine evacuation routes with starting points from locations with a history of landslides to evacuation sites. Determination of evacuation sites is based on capacity, accessibility, level of population exposure, availability of toilets, and open spaces. The results show that the level of population exposure in Karangpandan District is dominated by the high class, with 16 evacuation routes with a travel time of <10 minutes. Therefore, routes that pass through areas with high levels of population exposure and have shorter travel times can be prioritized as the main evacuation route.
