Threats to Natural Ecosystems in South America published

A DAPA article has been formally published today which looks at the threats to natural ecosystems in South America, and maps out the hotspots of possible conversion over the next 5 years.  The article, published in the Journal for Nature Conservation Volume 18 Issue 3, is the result of a long-standing collaboration with The Nature Conservancy.  In this analysis DAPA have developed a spatial model for evaluating threats to natural ecosystems, and applied it to South America.  The results are spatially explicit maps of likely threat to conversion of natural ecosystems over the next five years, from a range of anthropogenic activities including oil and gas, agricultural conversion, grazing pressure, infrastructure, fires, and accessible population.  Check out below the aggregate threat level that the analysis produces for South America.
