In Brazil, the battle for land is turning increasing deadly. Half the country's land is owned by just 1% of the population and those calling for reform often find themselves a target. The "Farmers Without Land" Movement says 61 activists were murdered last year in Brazil - up 20% in a year and the highest figure in more than a decade. The violence is centred around the northwestern state of Amazonas, which has seen a rapid expansion in mining, intensive farming and the lumber industry.
