Abstract: Civil society at first was a concept of Europe instrumental in modernization by opening a public space for various sectors of the society to participate in policy-making, voicing opinions and raise matters to influence or pressure the state to address their social needs under prevalent contexts such as cultural conditions, capitalist economic development and democratic governance. Since, such concept migrated to Thailand, it has been arbitrarily favored by authorities from different sectors as a rightful and sustainable solution to almost every issue in Thai society including those of environmental aspect. This study is thus intended to construct some observations on the realities of civil society adoption in contexts of Thai society with an emphasis on environmental civil society, through critical analysis and reflection on the “source-status-prospect” of contemporary environmental civil society in Thailand on open platforms accessible for the researcher through various forms of media along with reviewing relevant literature, concepts and theories of both domestic and foreign origins. The initial findings revealed some dissimilarities in terms of the people’s fundamentals as well as accumulated experience and social norms which essentially facilitate the maturation and practicality of civil society concept between Thailand’s and that of modern Western society the original model. Therefore, an acknowledgement and establishment of a perception that does not deviate far from reality on these different features and principles are considered a vital groundwork to an efficacious implementation of such concept.
