Amber Bracken's picture, entitled Kamloops Residential School, has been named World Press Photo of the Year.

The photos show indigenous Australians strategically burning land in a practice known as Cool Burning, in which fires move slowly, burn only the undergrowth, and remove the build-up of fuel that feeds bigger blazes.

The series featured the Nawarddeken people of West Arnhem Land, Australia, who have been carrying out the practice for tens of thousands of years.

The jury chose Amazonian Dystopia by Lalo de Almeida as the winner of the Long-Term Project Award.

The photos, taken for Folha de São Paulo and Panos Pictures, show the threat to the Amazon rainforest from deforestation, mining, infrastructural development and the exploitation of natural resources under Brazil's President Jair Bolsonaro.

"This project portrays something that does not just have negative effects on the local community, but also globally, as it triggers a chain of reactions," said Ms Effendi.

The series also won the Stories award in the regional Southeast Asia and Oceania category.

Blood is a Seed, by Isadora Romero, was awarded the World Press Photo Open Format Award.

Through personal stories and a journey to Ms Romero's ancestral village of Une, Cundinamarca, Colombia, the project questions the disappearance of seeds, forced migration, colonisation, and the subsequent loss of ancestral knowledge.

The World Press Photo regional winners were also announced, some of which can be seen below, with captions from the competition.
