Environmental Impact Assessment (EIA) is a measure that needs to be conducted according to the law, as stated in the Thai Constitution. It is necessary, therefore, to have local people participate in the consideration and decision-making process when a project, which will generate meaningful public participation is conducted in their area. In order to conduct any project with a sustainable development goal that could conserve abundance and diversity of natural resources, food security, sustainable careers and especially the way of life that is dependent upon natural resources, we need to accept that conducting large-scale projects in Thailandstill lacks proper assessment processes, including specialists to study and consider environmental impacts. As a result, developing the country under capitalism that is focused on urgency is currently creating several mistakes, as can be seen from the increasing environmental problems emerging from the various development projects. These accumulated environmental problems have become wounds for the surrounding communities and tendto increase exponentially and more seriously in future.
