Abstract

Ly Son island district belongs to Quang Ngai province in Central Vietnam. The community here has a long history and the process of exploiting the sea in the East Sea of Vietnam. The residents' lifestyle and livelihood closely linked to the sea are clearly shown through the rich and diverse cultural heritage system on the island. Approaching from community archaeology, the article clarifies the role of the Ly Son island community in the process of creating, maintaining, and preserving historical - cultural relics. The preservation and promotion of cultural heritage are intrinsically tied to socio-economic development. Sustaining traditional livelihoods, such as fishing and agriculture, enables communities to maintain their cultural heritage, which precisely reflects their historical, economic, and social trajectory, especially within island communities like Ly Son Island District. Drawing from research and practical surveys, the article suggests various approaches to enhance the community participation, supporting the development of cultural policies by authorities at all levels for Ly Son island district amid its urbanization and modernization journey. The cultural heritage preservation by and for the community lays a solid foundation for the sustainable development of Ly Son island district’s economy, culture, and society, while benefiting Vietnam’s coastal communities as a whole.
