This project conduct an ethnographic analysis of the imaginaries of technology-driven green transition initiatives focused on the Amazon. The destructive exploitation of the Amazon rainforest has for long been central to the Brazilian economy. In response to the environmental and climatic consequences, recent initiatives propose an economic model supported by advanced ‘4.0 technologies’ that claims to develop local resources without environmental degradation and without marginalising the people living in and off the rainforest. While such initiatives present themselves as exemplars of green transition, they bring into question how the conflicting interests of disparate stakeholders (e.g. indigenous groups, settlers, scientists, and entrepreneurs) can be negotiated, and how the new technologies affect their relationships to each other and to the rainforest environment. Our project thus addresses how green transitions can be implemented in practice and what role(s) new technologies may play in this regard.
