That old safe haven, gold, could well seal the destiny of at least part of the forests of the Guiana Shield. This is what emerged from work by researchers from CIRAD, the CNRS and the University of Guyana, published in the journal Environmental Research Letters . For the first time, the scientists involved used maps of annual deforestation based on high-resolution satellite images to examine the impact of gold mining on the tropical rainforests of the Guiana Shield between 2001 and 2014. This new analysis, which covered Guyana, Surinam, French Guiana and the Brazilian state of Amapá, showed that when gold prices rise, deforestation increases, and that when they fall, deforestation decreases. It also revealed subtantial disparities from one country to another, which would warrant drafting more coordinated regulatory policies on the scale of the Shield, and casts doubt on the relevance of global deforestation control mechanisms such as REDD+.
