Circular economy and community participation in Chao Phraya river Conservation: Evidence from Thai urban riverside communities

The conservation of the Chao Phraya River faces significant challenges, including environmental degradation, limited community participation, and insufficient integration of circular economy principles. This study aims to identify factors influencing pro-environmental behaviors and develop guidelines for enhancing community participation in river conservation. A quantitative cross-sectional approach was employed, collecting data from 402 respondents in Ang Thong Province through structured questionnaires. Descriptive and inferential statistics were applied to analyze relationships between socio-economic factors, knowledge, opinions, awareness, and waste management behaviors. The results revealed a strong correlation between knowledge of circular economy principles and effective waste management behaviors (r = 0.620). In addition, high awareness, gaps in practical implementation, particularly in waste donation and recycling, were observed. By addressing these challenges, this research offers actionable recommendations, including targeted education campaigns, incentive structures, and policy integration. The study contributes to the understanding of how socio-economic and cognitive factors drive pro-environmental behaviors, while practically, it provides a framework for sustainable conservation strategies applied to urban riverside communities.
