摘要：AbstractGreen open space is always a discourse in urbanization context. Research and policy sometimes couldn’t match each other because research typically has been done more advance and faster than policy implementation. On that condition, smart city is a paradigm to be considered as a tool to gain sustainability. This research identifies the environmental degradation on Green Open Space (GOS). This research was done by primary and secondary data collecting, social media, and interview along the process. The research takes two cities as locus Batu City in East Java and Yogyakarta City. This research put some sample in Japan and Taiwan as lesson learned. The result has shown that it needs more commitment from local government on providing green open space on both city and using campus as main role model. Furthermore, government should provide people with smart platform to report disobedience of land using so that real time updatecould be monitored.
