Investigating urban space: Potential urban green space in dense city of Yogyakarta

Urban green space (UGS) is essential for the city to ensure sustainability. The provision of adequate USG, however, is challenging over time, particularly at the city centre area. This study aims to offer a possible framework to identify UGS and assess the potential share from the vacant land into green space using descriptive analysis of remote sensing and secondary data. A case study is applied to assess the UGS and potential area in Yogyakarta City. The result shows that the built-up area in Yogyakarta City is covered around 85 of the total while the UGS remains halved within less than a decade. In addition, the field visit shows a potential UGS on 16.00 ha from the private vacant land. The application of the framework provides a tool for the city council in maintaining and monitoring the land cover, including identifying the UGS throughout the city. Imposing the regulation on vacant land might encourage the private sector involvement and offers less effort to the city council in providing UGS.
