The United Nations Environment Programme (UNEP) published ＂The Adaptation Gap Report 2018＂ in December 2018 to promote adaptation to global climate change in the realm of public health. This report notes that we are still far from being able to cope with the impacts that many scientists are predicting. In addition, this report calls on countries to construct the Climate Resilience of Health System, which is a multidisciplinary approach to building the capacity necessary to prepare for and adapt to extreme weather. Strategies for adaptation require not only top-down integration from national and regional governments but also bottom-up participation from communities and individuals. This article aims to elucidate the concept of community-based adaptation to climate change and presents applications of this concept. Because the government is promoting the national policy of ＂Regional Revitalization＂, the sustainable community may be built if this policy takes into account adaptation to climate change.
