Wildfires in Chiang Mai are one of the disasters that have been researched for over a decade because it causes the smog phenomenon. This paper aims to unravel the space issues in the wildfire situation in Chiang Mai, Thailand to emphasize the importance of community-based wildfire management. The literature review method was used to study the wildfire situation, and state official policies, and use the production of space concept to explain and interpret the relation of space and community in wildfire management. It was found that, in the case of Chiang Mai, wildfires management has continued to develop positively. However, even if the power is decentralized to the local community, there is still a sense of top-down management. All of these are reflected in 3 space issues. Firstly, Physical Space affects wildfire management, both the terrain and the nature of the forest, including unclear boundaries. Secondly, Political Space demonstrates power and resource control. Lastly, Social Space demonstrates the relationship between communities and forest areas through interpreting experiences, history, knowledge of space management which every community is different. The different space issues this writing encounter resulting in decentralization and community-based wildfire management, both power and policy, should be emphasized.
