The present paper aims to critically re-examine how the concept of 'nature' is socially constructed by the colonialism as a different and separate category from indigenous culture. How the rise of ”environmental managerialism” has led to a problem-solving, and state-centered intellectual practices without paying sufficient attention to the broader political, social, historical and cultural contexts, is another important thread of the present paper. The author discusses extensively 1illeins-Braun's thesis (1997) on the representation of nature in the era of (post)-colonialism. The environmental and cultural consequences of developmental programs sponsored by international financial organizations, and the associated hegemony of ”scientific” knowledge vis-a-vis indigenous local knowledge are also explored. The author then shifts to the establishment of environmental discourse in Taiwan and promotes the empowerment of Taiwanese indigenous people as a way of de-colonization.
