The simple pleasure of diving into the Tapajos River in the Brazilian Amazon may soon be at risk for these children, as the region heads towards troubled waters.

The Tapajos is home to the Munduruku people, one of the largest ethnic groups in Brazil. Its people have lived in the area for at least three centuries.

The 1,930km tributary is also one of the last great Amazonian rivers without a dam. But that may change if the Brazilian government goes ahead with plans to build a hydroelectric dam that will flood much of Munduruku land.

Their leaders say they have a constitutional right to remain on their land, but that the government is refusing to acknowledge it.

This and 144 other award-winning photographs from the World Press Photo 2016 exhibition are on display at the National Museum of Singapore until March 26, from 10am to 7pm daily. The exhibition is presented by The Straits Times and admission is free.
