An old boat engine, a Brazilian-made two-cylinder Diesel Yanmar, on a truck chassis, a few welded steel plates, and a solid wooden rear box make up a precarious looking vehicle, but powerful in all its simplicity.
The four Borarí and Arapiun indigenous communities in Maró Indigenous Land (TI Maró) have been using it for over a year now. On it they can cover the entire perimeter of their territory in just a few days. On foot, as has they had been doing since the beginning, it takes much longer - about two weeks.
The Borarí indigenous group came only recently to this remote territory, in which the Arapiun had been living for centuries. They were fleeing poverty from Alter do Chao, a predominantly Borarí land, about 30 kilometers to the west of Santarém, the capital city of the Lower Tapajós, in the Brazilian Pará. They went along the Arapiuns River right up to its headwaters and, from there, they followed the course of the small Maró River, which gives the territory its name.
