Exploring neighborhood green space to mitigate UHI effect based on a spatial approach in Malang, Indonesia

Abstract

Urban Heat Island (UHI) is detrimental to climate and ecological conditions. Combined with the UHI effect, this can result in high temperatures; overcrowding worsens UHI due to increased human activity, energy consumption, and waste heat production. This research aims to explore neighborhood green space potential as UHI mitigation. This research uses a spatial approach to explore the configuration of neighborhood and greenspace patterns for UHI mitigation efforts. The research took areas in Malang City. They were selected based on LST values from Sentinel 2 data in the extremely hot, very hot, and near normal categories according to STI (Standardized temperature index). Data collection was carried out using ArcGIS with a spatial approach. The results show a medium greenspace dispersion in the concentrated greenspace category has a potential effort to mitigate UHI. It should be noted that the high and low greenspace dispersion scattered and concentrated greenspace categories are not optimal in mitigating UHI. Future research can look for other factors that can influence UHI mitigation.
