Urban green space accessibility changes in a high-density city: A case study of Macau from 2010 to 2015

Urban Green Spaces (UGSs) are important for urban residents' well-being, especially in dense urban areas. This study uses Macau, a high-density city in Asia, as a case study area and tracks changes in the distribution of UGS accessibility across space and across population groups from 2010 to 2015. Based on the two-step floating catchment area model (2SFCA), the results indicate that UGS accessibility is distributed unevenly across space and population groups in Macau. Over time, however, UGS accessibility became more evenly distributed, despite the decline in overall UGS accessibility. These changes are attributable to the policies of upgrading UGSs and building micro-scale UGSs. These results shed light on how future policies can enhance UGS equity in high-density urban areas.
