Sustainable Urban Development: Evaluating Green Open Space Availability Using Remote Sensing in Tangerang City

Sustainable urban expansion results in the conversion of natural green areas into developed zones, posing challenges in preserving green spaces that fall short of the mandated minimum of 30% green space availability. This study aims to assess changes in land use and evaluate the status and demand for green spaces in Tangerang City. The methodology employs supervised classification to identify land cover types. The findings reveal notable shifts in land cover types, particularly a significant increase in developed land from 25.96 km 2 in 2018 to 126.31 km 2 in 2023. This transformation has resulted in a reduction in green open spaces, declining from 68.89 km 2 (39%) in 2018 to 40.96 km2 (23%) in 2023, falling below the legal requirement of 30% green space availability. The green open spaces development is then needed since it plays a vital role in sustainable urban development as it provides green areas for its inhabitants, a crucial element in sustainable urban planning.
