Abstract

The Padolo Watershed (DAS), which spans Bima Regency and Bima City, is the main focus of hydrological disaster issues in West Nusa Tenggara (Nusa Tenggara Barat). This study aims to analyze the correlation between land cover change within the Padolo Watershed and the increase in the frequency and damage caused by flood disasters in Bima City during the 2017–2024 period. The methodology employed is a mixed-method analysis, involving qualitative literature review and quantitative time-series data analysis from BMKG (Agency for Meteorology, Climatology, and Geophysics) and BPBD (Regional Disaster Management Agency) data, coupled with a spatial analysis approach using land cover data from Esri | Sentinel-2 Land Cover Explorer. The results indicate significant land cover changes from 2017 until 2024, characterized by an increase in Built Area from 2,195 Ha to 2,904 Ha and a corresponding loss of natural forest land (Trees) from 8,283 Ha to 6,245 Ha. These alterations correlate with a high frequency and impact of disasters, which peaked in 2021 with 12 flood incidents and 3,427 submerged houses (Indonesian Disaster Data Geoportal). Bima City's naturally concave topography (often described as a 'water bowl') is further exacerbated by the degradation of critical land in the upstream area, resulting in persistent flood disasters even during years with relatively lower rainfall intensity. This analysis underscores the necessity of restoring the Padolo Watershed's carrying capacity through integrated, policy-supported management

Abstract

This study critically assesses regional development policies on Sumbawa Island, particularly the PIJAR program (Cattle, Corn, and Seaweed) and the corn nomenclature, through the perspectives of environmental ethics and critical theory. Employing a mixed-method approach, the research integrates a spatial analysis of land cover changes in the Padolo River Basin during 2017-2024 with a policy text examination based on Jürgen Habermas's theory of the "Colonization of the Lifeworld." The findings reveal that these policies reflect structural anthropocentrism, prioritizing economic production targets over ecological integrity in a top-down fashion. The consequence is a destructive transformation of the regional landscape, where the depletion of upstream forests triggers Policy-Induced Disaster phenomena, including increased frequency of floods and extreme droughts. The study concludes that the ecological crisis on Sumbawa Island is the result of a failed development vision that neglects the carrying capacity of nature and the government's inability to provide alternative employment opportunities for the community
