Ethnic minorities in the Northern Mountainous Region not only use the application of scientific-technological advances but also experiences of the community to enhance production efficiency and environmental protection. Local knowledge (TTDP) of ethnic minorities is useful for environmental protection and natural resource exploitation & use. These are environmental & weather knowledge; farming experiences on sloping and forestry land; knowledge about environmental protection and natural resource exploitation & use especially how to protect precious resources by specific rules/regulations of customary law. In the context of declining natural resources, TTDP is eroded, captured, or illegally exploited. There should be measures in order to preserve and promote TTDP as well as raise the awareness of the community about its important role.
