Eha tradition has been arised from  a long historical journey of the Indonesian people in the outer islands of the Talaud Archipelago Regency, who often experience disasters threatening their natural resources for their livelihoods.Thus, the Eha tradition was maintained, as a rule to control the use of natural resources both in sea and land, to prohibit people from taking agricultural products outside of their time. At the time determined according to natural conditions and the calculation of the best harvest period, a joint harvest is held  out together with a thanksgiving party, namely mane'e, manam'mi, maniu. This custom is revived because, only a few village maintain it. Changes in society in all its economic needs have caused the loss of this tradition. Some villages still maintain it, such as Kakorotan village, Miangas village, and Ambia village. They consider this tradition as a legacy of their ancestors to survive or adapt in the Talaud archipelago environment in which disasters often occur so that its natural resources must be protected. This paper is a preliminary study to explore the unique eha tradition on the Indonesia-Philippines border especially in the Talaud archipelago. This research uses a qualitative approach through interviews, focused discussions, observations and document studies.
