Abstract
Global drought conditions pose a serious worldwide problem, exacerbated by climate change, deforestation, and excessive water extraction. At the local level, South Tangerang City is grappling with drought challenges due to an extended dry season. Drought mitigation efforts entail the distribution of clean water and public education. The use of innovative remote sensing technology becomes crucial for drought monitoring and management. This study aims to integrate NDVI, NDWI, and NDDI modification methods with multi-year Landsat data to analyse drought in South Tangerang City. The study site focuses on a region characterized by flat to undulating topography and a wet tropical climate. The utilization of Landsat 8 OLI as study data provides comprehensive information through various image bands. NDVI, NDWI, and NDDI analysis methods offer an overview of vegetation conditions, water availability, and drought levels. The results demonstrate a correlation between drought and a decline in vegetation health and water availability. Landsat data from 2008 to 2023 illustrates variations in drought levels in South Tangerang City. This research offers in-depth insights to governments and stakeholders, aiding in the formulation of effective and sustainable drought management strategies at the local level.
