Buffer zone management is a worldwide requirement due to substantial economic activities and environmental degradation. This element necessitates the researchers' goal, and the current research explores the influence of ecological justice, such as reduced air and water pollution, appropriate transportation, and adequate access to nutritious food, on buffer zone management in Indonesia. The research also analyzes the moderating effect of contented and motivated individuals on air and water pollution reduction, appropriate transportation, adequate access to healthy food, and buffer zone management in Indonesia. The article uses survey questions to obtain data from respondents using smart-PLS to examine the relationship between factors. Reduced air and water pollution, appropriate transportation, and access to healthy food were found to have a beneficial relationship with buffer zone management in Indonesia. In addition, the results demonstrated that contented and motivated individuals significantly mediate the relationships between reduced air and water pollution, appropriate transportation, adequate access to nutritious food, and buffer zone management in Indonesia. The paper assists policymakers in formulating buffer zoon management policies by promoting ecological justice.
