Urban green space optimization in Sorong City of Southwest Papua Province based on environmental carrying capacity and environmental capacity

Abstract

Immediate action is required to optimize the urban green open spaces in Sorong City to meet the obligation of increasing the baseline from 8.21% to 32.96%. The process will involve several stakeholders, including the Regional Government of Sorong City and Southwest Papua Province, Vertical Institutions, University of Papua, Development Partners, Indigenous Peoples, Media, and Private Parties. Upon evaluating the starting conditions in Sorong City, it is observed that the Environmental Quality Index (EQI) value stands at 58.96, indicating a sufficient category. This is mainly attributed to the detrimental impact of river water pollution (Water Quality Index, WQI) and the diminished coverage (Forest Cover Index, FCI) resulting from various commercial activities in metropolitan areas. Given the escalating climate change and the rise in hydrometeorological disasters, particularly heavy rainfall, erosion, and landslides, Sorong City must maximize the utilization of open green spaces (GOS). By improving the GOS, it was found that the Sorong Green Index (SGI) value was 94.77 in the outstanding category. In addition, utilizing the POAC approach for management analysis, it is imperative to promptly take necessary measures for various functions that are now inactive. The parties are expected to fulfill the task of job tagging and budget tagging to establish regional action plans.
