Identification of Green Spaces Availability and Surface Temperature in South Jakarta
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.
