Article covering the new campaign by Survival International, backed by Colin Firth, which looks at the plight of one of the last remaining nomadic hunter-gathering Amazonian tribes whose existence is under threat from the activities and violence carried out by illegal loggers and cattle ranchers. Despite the overall decrease in the rate of deforestation in Brazil, the state which is home to the threatened tribe has recorded a sharp rise in deforestation.

A remote sensing company has signed a deal with the Brazilian space agency to deliver near real-time satellite imagery to monitor forest clearing in the Amazon rainforest and target illegal logging as it happens. Illegal loggers have grown smart to the current monitoring system by clearing smaller areas to evade detection but the new system will provide a much higher level of granularity in its imaging. Such technology is seen as important in the development of an effective REDD+ programme.
