Social Impact Assessment for Seawall Project: A Case Study of Maharat Beach, Sathingpra District, Songkhla Province

Problems with coastal erosion result from human activities, natural forces, and the effects of climate change. The guidelines for solving the problem of coastal erosion in Thailand are divided into three measures: green, white, and gray measures. Hence, this study aims to assess the social impact of the Seawall Project: A Case Study of Maharat Beach, Sathingpra District, Songkhla province, and quantitative research. Using a systematic random selection method, 76 samples of impacted individuals in the area were selected to provide the data, which consisted of four dimensions: Land used, Infrastructure, Social, and Living. The findings of this study revealed that the dimension of land use has the highest influence, with an average of 3.59. On the other side, the infrastructural dimension has the lowest impact level. With an average of 2.79, the impact was moderate. There was a significant difference in the average land use, infrastructure, and living impact levels among occupational groups at the .05 level. According to the white measure, the findings support an integrated approach to preventing and solving coastal erosion problems by Coastal Equilibrium by Natural Processes. The buffer zone must be a specific distance from the sea, and the use of space must be appropriate to the rate of coastal erosion in parallel with the gray measure, using the original engineering structures that have been completed. The contribution of this study was consistent with the Sustainable Development Goals (SDGs) in goal 14.
