Abstract

The effect of high population density is the reduction of green space areas, which enhances the risk of climate change impact. Green space has multifunction roles in ecology, social and economics. The provision of green space can reduce heat and pollution, improve water management and support health and well-being, essentially in densely urban areas. This study aims to identify the availability of green space areas considering the vegetation density and their implication for land surface temperature in South Jakarta. A remote sensing approach is deployed with the Normalized Difference Vegetation Index (NDVI) to analyze the green space areas and LST to identify the temperature of each district. The result shows that the majority of the district in South Jakarta has increased the number of green space areas. While the surface temperature in the neighbourhood, with growing green space areas, has the lowest temperature in 2021, Setiabudi District. On the other hand, Tebet District experienced the highest land surface temperature in 2021, around 29,6oC, which dedicated only 3.54 Km2 of green spaces, the smallest area amongst districts in South Jakarta.

Abstract

The littoral zone is the most vulnerable area to the impacts of climate change and human activities. Current weather anomalies and the development of human activities in coastal areas are on the rise. Remote sensing and geographic information system approaches have been widely used to monitor shoreline changes using easily accessible satellite imagery. This study aims to identify the dominant factors driving littoral change at Bantul Beach and assess the relationship between tourism activity and coastal abrasion. This study uses the Geographic Information System (GIS) analysis method using Landsat-8 satellite imagery from 2013 to 2023. In monitoring shoreline changes, NDWI and DSAS analyses were conducted to identify factors influencing coastal changes. A study was also conducted to examine the parameters of the coastal profile, wind, waves, tides, and human activities. Based on 10 years of image data, the study location has generally experienced high abrasion, with an average EPR value of -1.51 m/year, an average SCE value of 47 meters, and a dominant negative NSM value. The most influential factors are the slope of the shoreline and waves, especially during high waves or storms. The increase in the number of tourists in Bantul Yogyakarta tourism spots is not linearly correlated to the occurrence of abrasion. There needs to be coastal protection and mitigation that prioritizes the dominant factors causing abrasion, utilizing a soft engineering approach and local wisdom.Keywords: Shoreline changes, Tourist Coastal Areas, DSAS, Landsat-8, Bantul Yogyakarta
