Urban green open space area is one of the strategies to deal with climate change mitigation and adaptation issues. As one of the relevant exemplifications of the “Urban Forest” concept and sustainable urban development, legal control of urban green open space is necessary to support the effort. This study examines urban green open space policies, practices, opportunities, and challenges in Bogor city regarding climate change mitigation and adaptation. Furthermore, local regulations, including legal issues, key players, and their roles in urban forest management were also discussed. A desk study with descriptive exploratory was implemented in this paper. The results showed that there are challenges in the implementation of urban green open space area policies into urban forest practices. The land size allocation for urban forests in Bogor, West Java, is still not by the existing policies as their land size is far less than 30%. Moreover, most local regulations have relatively paid little attention to private property policy. Local governments can enact local regulations for technical guidelines in short-term strategy as local regulations are expected to support the regional level of urban forests and green open space development. Multi stakeholders’ cooperation and community engagement are potential initiatives for urban forest development at the local government level for climate change resilience.
