Mapping of Public and Private Green Space Distribution in Makassar City, South Sulawesi

Abstract

Abstract Green Open Space (GOS) is essential for creating sustainable, healthy urban environments by improving air quality, providing recreational areas, and supporting ecological balance. However, cities in Indonesia like Makassar, are facing a growing shortage of green spaces due to rapid urban expansion. While urban green space mapping has been studied globally, there is limited research specifically focused on the distribution of both public and private green spaces in Makassar. This lack of detailed data complicates efforts to plan and develop green spaces effectively, especially in line with national targets. This study aims to map and assess the availability of public and private green spaces in Makassar City using high-resolution satellite imagery and the Soil-Adjusted Vegetation Index (SAVI). The goal is to identify current green spaces and explore areas that could be developed to help reduce the city’s green space deficit. Based on analysis in 2024, Makassar has only 12.39% GOS, well below the required 30%. Public green space makes up just 5.55%, and private space accounts for 6.85%. The city faces a shortfall of approximately 3,275.67 hectares, with districts like Biringkanaya and Tamalanrea experiencing the most significant gaps. The findings highlight the need for urgent action to expand GOS in Makassar. Potential solutions include converting agricultural land, developing roof gardens, and prioritizing green space in urban planning. These efforts are crucial to meeting regulatory targets and enhancing the overall sustainability and quality of life in the city.
