Tres Unidos has about 2.000 inhabitants and lies deep into the Amazon region. Its economics were formerly based on growing cocoa and being a reloading place for these plants. With the downturn of cocoa trade, village people lost their main source of income and had to turn on growing sugarcane and corn instead.
The best farmland is on the opposite side of the Mishquiyacu River. Depending on the time of the year, the river can swell up to 3 meters (10 feet) in depth, and reaching the opposite side then takes about one and a half hour by foot.
Since their farmland is so difficult to reach, the children helping in the fields are not able to attend school. Tilling the fields and harvesting of the crops becomes a strenuous and intricate business once the river starts to swell after a rainfall.
