The Xishuangbanna rainforest is located at the northern edge of the Indo-Malayan rainforest region, one of the three major rainforest systems in the world, with the temperature and rainfall conditions at the lowest level of the rainforest ecosystems, which is one of the regions with high vulnerability to climate change. Man Wa Old Village is located in the Southwest of Xishuangbanna Prefecture, China. The intensity and frequency of extreme weather triggered by climate change are increasing, which poses considerable challenges to the production and life of villagers. With the assistance of the Mueang-Nam Sustainable Development Services Center (MNSC), Man Wa Old Village has started to take the initiative to adapt to the impacts of climate change by exploring traditional knowledge systems in a holistic way and developing community education based on these knowledge; external knowledge is also brought into this adaptation process. In addition, villagers shared their experiences with other Bulang villages through cross-village exchange meetings for knowledge dissemination. We conclude that for climate change adaptation at the community level, revitalizing traditional knowledge is critical but may not be sufficient to cope with rapid new changes. It is necessary for villagers to learn new knowledge and techniques based on their traditional knowledge.
