The charity Survival International has launched a photographic competition to raise awareness of tribal peoples as they try to defend their lives, lands and lifestyles. The contest is open to both amateurs and professionals – judges will include Survival's director Stephen Corry and actor Gillian Anderson who is an ambassador for the charity. The winning entries will be published in a calender and exhibited at The Little Black Gallery in London. Here are some images for inspiration
