The article presents an anthropological understanding of recent transformations in Brazilian socio-environmental policy and arena, with an emphasis on the social effects of national development programs and projects on territorial rights of indigenous peoples and traditional communities. It is an attempt to understand the country's recent political situation based on the production of the commissions and committees of the Brazilian Association of Anthropology – specifically its Committee on Traditional Peoples, Environment and Large Projects – understood as peculiar loci of knowledge (...) production and political advocacy. It demonstrates, through the evidence that those chapters of ABA offer, that the attacks against the environmental legislation and the recognition of the territorial rights of indigenous peoples and traditional communities are not exactly a recent phenomenon. Following Andrea Zhouri's interpretation, the rise of official anti-environmentalism and the ongoing institutional dismantling of the environmental rule represent a predictable outcome of its gradual deregulation, through a path that goes from slow, subtle and barely visible violence, to the open, naked and crude violence of the current overtly anti-environmental and anti-indigenous policies.
