Acre

Acre is a state in western Amazonia, bordering Peru and Bolivia, covered largely by rainforest and crossed by rivers that flow into the Amazon basin. Small towns and remote communities dot the landscape along the few paved roads that cut through the forest.

The territory was ceded from Bolivia to Brazil in the early twentieth century after rubber tappers from the northeast established settlements there. Statehood came decades later as the region integrated further into the Brazilian federation.

The Federal University of Acre in Rio Branco maintains research programs focused on Amazonian biodiversity, traditional medicine, and regional development studies.

The capital Rio Branco serves as a starting point for travel into remote areas, with river boats and small planes often the only links to distant settlements. Rainy and dry seasons shape access to many routes and waterways inland.

Archaeologists have found geometric earthworks beneath the canopy, believed to be made by societies that lived in this part of the rainforest long before Europeans arrived. These structures suggest the region was more densely populated than once thought.
