The purpose of this study is to explore a more systematic and sustainable way to sustain the Hadong traditional tea farming registered as a national important agricultural heritage and world agricultural heritage which has been survived in the traditional agricultural culture for a long time by cooperating with a local museum which has functions and roles to preserve local heritage. Agricultural heritage means all products, including the traditional agricultural activities and systems that have been formed and evolved for a long time by the farmers adapting to the local environment, society, and customs, and the resultant rural landscapes. Established in 2002 by the Food and Agriculture Organization, the World Important Agricultural Heritage System has been introduced to preserve and succeed traditional agricultural systems, landscapes, biodiversity, and land use systems that have long been shaped by adapting to the environment, society, and customs to pass down to the next generations. It recognizes the unique land use systems and ecosystems that have been damaged and disappearing due to radical social changes and development-oriented policies, thereby safeguarding such tangible and intangible agricultural heritage. The Hadong traditional tea farming has been maintaining its reputation for more than a thousand years based on the sense of co-existence of a local community and its environment. Today, the Hadong wild tea agricultural heritage is leaping beyond the region and toward the world. For a more efficient and sustainable heritage, cooperation with a local museum that is responsible for preserving and conserving the cultural heritage and natural heritage of the community is very important. Through the museum which plays a key role in locating the identity of the local people, it will be able to shine the sense of coexistence underlying the agricultural heritage that has been transmitted so far.
