Members of 24 Brazilian tribes and native people from 23 other countries around the world are competing in the first World Indigenous Games in Palmas, northern Brazil. The nine-day event features traditional disciplines such as canoeing, archery, tug of war and a relay race with a tree trunk.
Brazil is home to nearly 900,000 indigenous peoples, speaking a total 274 languages. Worldwide, it is estimated that there are 370 million indigenous peoples, making up more than 5% of the world's population. In this gallery, we look at some of the sports and the people at the games.

A noisy demonstration broke out during the 100m race at the World Indigenous Games. The crowd, made up mostly of native Brazilians in traditional dress, were outraged over a land demarcation proposal that they say would be catastrophic for Brazil's 300 or so surviving tribes.
The proposed constitutional amendment would transfer the right to demarcate indigenous lands from the executive branch to Brazil's Congress, which is heavily influenced by the powerful big agriculture lobby that has fought against indigenous reserves in the past.

A committee in Brazil's Chamber of Deputies has approved the proposal, but it must get through the full lower house and Senate, then be signed by President Dilma Rousseff in order to become law.
