Stakeholder's opinion of public participation in Thai environmental and health impact assessment

This paper evaluates the efficacy of public participation in the EHIA (environmental and health impact assessment) process of Thailand based on the opinions of 53 interviewees from various stakeholder groups in relation to certain public participation criteria. The evaluation revealed that public participation in Thai EHIA was partially effective. The project proponents provide an opportunity to anybody interested in the project to get involved from the scoping stage onwards. However, the important decisions are already made before the public can get involved. In addition, government officers and non-governmental organizations appear to be able to influence outcomes of public hearings more concretely than the project-affected people due to the highly technical nature of the discussions. The stakeholders were questioned whether their concerns were taken seriously during the decisionmaking process. In our conclusions, we make three major recommendations to enhance the public participation process and practice in Thai EHIA, based upon: (1) stakeholder analysis, (2) public participation in EHIA guideline revision, and (3) validation the authenticity of the concerns raised by stakeholders.
