The scale of climate change put indigenous people at higher risk than the others. Nonetheless, due to their intimate knowledge of their land, traditional ecological knowledge (TEK) held by the indigenous peoples may be the key to combating climate change. This article aims to explain the role that TEK plays in adapting to climate change. Document review included grey literature alongside peer-reviewed literature and project websites related to indigenous knowledge in climate change adaptation. The findings show that TEK not only helps indigenous people cope with environmental and climate pressures, but the knowledge system fosters resilience of socio-ecological systems.
