During the period from July 23rd to September 27th, 2015, a group of members of the ministry-level project titled Dug-out Canoes in the Lives of Ethnic Peoples in the Central Highlands implemented many field trips in 30 villages of such ethnic groups as Mnông, Giarai, Banah và Xơđăng in three provinces Đắk Lắk, Gia Lai and Kon Tum. During these trips, in addition to on-site surveys, the group also collected documents from three provincial museums, two churches, and one private museum. Fieldwork notes indicate that the growing of various means of transportation and the development process of hydroelectric projects have impacted on the use of dug-out canoes in the lives of ethnic peoples living in the area. At present, the demand of using dug-out canoes is lower than before, partly because of the increasingly scarceness of raw materials. This is also a big challenge for the preservation and promotion of dug-out canoes’ values in the current context of these ethnic groups’ lives in the Central Highlands.
