During the 70’s, while the TransAmazonian Highway was being built, the Gaviao Indians suffered a traumatic phase of “pacification” in wich more than 70% of the population was lost. Since then the survivors are trying to rebuild their ancestral way of life, however, their lands are being violently looted over and over again, surrounded by large development projects in the region to export minerals. In recent years, the Indian Reserve has been crossed by one of the largest railway in the world, measuring more than half a kilometer and exports most of the world mineral reserves in the Para Sate to Sao Luiz de Maranhao, in the Ocean Atlantic, and from there to the rest of the world. The continued repression of their traditional lifestyles have led to fragmentation of the community ties. Today, all that remains of their union and community sympathy are a couple of festivities per year. Today this town is no longer producing anything. The compensation of the companies that have devastated their environment have served to have some new houses and to buy bread, fish and rice from a peddler who once in a while passes with his truck across the Indian Reserve.
