In 1998, the government established a data-collection system called PRODES, based on Landsat 5 and 7 observations. Satellite-based forest monitoring systems played a key role in slowing deforestation, explained Raoni Rajão, an expert in environmental policy at Federal University of Minas Gerais. The turnaround was heralded as one of the world’s most dramatic environmental success stories. By 2012, forest clearing was down nearly 80 percent, or roughly 5,000 square kilometers (1,900 square miles) per year. Within a few years, large-scale deforestation dropped by roughly 50 percent. The government created a large network of national and state parks, established protected territories for indigenous groups, strengthened environmental enforcement agencies, made it more difficult to export goods produced on illegally deforested land, and strengthened satellite monitoring systems. That was the year the Brazilian government adopted an aggressive policy called the Action Plan for the Prevention and Control of Deforestation in the Legal Amazon (PPCDAm). In 2004, following several years of particularly rapid deforestation, public pressure turned the tide. “Ranchers, soy farmers, land speculators, loggers, and miners were coming to the frontier and clearing virtually anything they wanted.” “It was open season on the rainforest back then,” said Michael Coe, a senior scientist with the Woods Hole Research Center. Scientists have used satellites to track the deforestation of the Amazon rainforest for several decades - enough time to see some remarkable shifts in the pace and location of clearing.ĭuring the 1990s and 2000s, the Brazilian rainforest was sometimes losing more than 20,000 square kilometers (8,000 square miles) per year, an area nearly the size of New Jersey.
