This study delved into the cultural capital, value systems, and social organizations in sea salt farming in Ban Laem District of Phetchaburi Province, considered within the framework of GIAHS. The research methodology involved qualitative tools such as in-depth interviews, SWOT analysis, and TOWS matrix, and focus group discussions with key stakeholders such as salt farmers, community leaders, local government officials, and scholars. The study underlines that the sea salt production in Ban Laem District is deeply rooted in both tangible and intangible cultural traits, contributing to the area’s distinct cultural identity. The traditional ceremonies, foods, crafts, and tools associated with salt production form the tangible cultural aspects unique to the area. Sea salt farming’s historical, aesthetic, scientific, economic, and social values accentuate its community-wide importance. However, challenges such as traditional knowledge and practice erosion, skilled labor scarcity, limited comprehension of Good Agricultural Practice (GAP), environmental degradation, and globalization’s impact threaten the cultural authenticity of the salt farming community. To counter these challenges, this study recommends preservation of traditional knowledge, cultural value awareness, reinforced environmental conservation, and fostering collaborations among salt farmers, governmental bodies, and the private sector. Collectively, these efforts will contribute to the sustainability and resilience of Ban Laem’s sea salt cultural heritage.
