Oil production in Ecuador is a leading economic activity. It started at the ends of the 1960s and it has been concentrated mainly in the northern Amazonian region. By the beginning of the XXI century, the Ecuadorian government wanted to expand this activity into the centre-south of the Amazonian Region. This area is also the ancestral territory of diverse indigenous peoples. With this propose, the Ecuadorian government called for the IX Oil Bidding Round which included the Amazonian oil blocks 20 and 29. Unlike the previous experience of oil production, this time Ecuador had a new legislative framework in which indigenous collective rights were acknowledged. Among them, it was included the right to prior consultation regarding economic activities such as oil activity in indigenous territories. This right did not grant indigenous peoples with the veto option. Within this context, the Ecuadorian government through the Salesian Polytechnic University carried out the process of consultation for the oil blocks 20 and 29. During the process, incipient local resistance emerged linked to local environmental organizations opposed to oil activity. Once it finished, due to the way it was carried out, many local organizations joined together to fight for the nullity of the process.
