Indian lands, environmental policy and military geopolitics in the development of the brazilian Amazon : the case of the Yanomami /Albert, Bruce ENVIRONNEMENT CONFLIT FONCIER EXPROPRIATION LEGISLATION GEOPOLITIQUE ONG PROJET DE DEVELOPPEMENT POLITIQUE DE L'ENVIRONNEMENT POLITIQUE INDIGENISTE INDUSTRIE MINIERE POUVOIR MILITAIRE This article examines the realignments of the developmentalist discourse and strategy of the Brazilian military for the Amazon during the civilian government of the "New Republic" (1985-90). It focuses on a case study, i.e. the official expropriation of the lands of the Yanomami Indians in the states of Roraima and Amazonas along the Brazil/Venezuela border. The analysis brings to light how, during this period, the military aimed at neutralizing both the pressure of environmental NGOs on Brazil's international creditors and the emergent democratization of decisions on land use in Amazônia. It shows how such attempts involved manipulating environmental legislation and ecological rhetoric in order to perpetuate militazy hegemony over the development of Amazônia to the manoeuvres to a geopolitical and economical model for Amazonian integration still inspired by the national security doctrine drawn up in the 1950s and 1960s by the Escola Superior de Guerra.
