The Brazilian government has said forest clearance in the Amazon has decreased by 18% over the past year to July 2014, but environmental NGOs disagree saying their data shows increased rates of forest loss. Brazil’s environment minister, Izabella Teixeira, said approximately 4800km2 was lost between August 2013 and July 2014. This was down from 5900km2 during the same period a year earlier. But WWF and Imazon disagree and say that alternative satellite monitoring systems, different to those used by the government, show a staggering increase in forest loss of over 460%. Ms Teixeira maintained that the official government estimate was the most accurate: “Anything else is speculation. We have been working hard to end deforestation.”
