Living in a hot city: thermal justice through green open space provision

Jakarta's environmental problems, the increasing temperature, and the intensifying urban heat island effect (UHIE) add weight to the deteriorating quality of life in the city. Nevertheless, chronic exposure to heat, especially experienced by inhabitants in tropical cities, receives less attention. It is often seen as a low-onset event that requires no immediate action and is not as noticeable and apparent as other heat events, such as heat waves. This slow onset environmental hazard disproportionately affects the population in the lower socio-economic condition. With their low access to cooling infrastructure, the disadvantaged people of Jakarta live and work in an environment prone to extreme heat exposure. Poor urban planning and design contribute to the intensifying urban heat in Jakarta and exacerbate the impacts of heat by providing mitigating and managing urban heat in the city. Using the Multiple Stream Framework (MSF) lenses, we analyse how and why the issue of urban heat is currently being prioritized in Jakarta and how the provision of green open space contributes to thermal justice in Jakarta. The issue is examined by analyzing urban planning policy through government strategy documents and interviews with key stakeholders. The findings reveal that while there is a growing awareness of urban heat issues in Jakarta, they are often overshadowed by other strategic issues in the policy arena. The research underscores the significance of incorporating urban heat issues into urban policy agendas and promoting equitable distribution of green open space in Jakarta.
