A press release from the University of Bonn: The destruction of the Brazilian rainforest has slowed significantly. With around 5000 square kilometers annually, the loss is now about 80% lower than in 2004. Led by the Center for Development Research (ZEF) at the University of Bonn, an international team of researchers has evaluated the effectiveness of forest law enforcement in the Brazilian Amazon. In some federal states of the Brazilian Amazon region enforcement has been more effective than in others. The results are presented in the journal "PLOS ONE".Deforestation of the Amazon rainforest featured in international press headlines for a long time. However, Brazil has made substantial efforts to protect rainforests ecosystem services lately. "Over the last decade, there has been a significant decline in deforestation," says Dr. Jan Börner, the Robert Bosch junior professor at the Center for Development Research (ZEF) of the University of Bonn. According to national statistics, in 2004, 27,772 square kilometers of forest fell victim, primarily to agricultural use; by 2012, deforestation had decreased to 4,656 square kilometers.
Rainforest destruction is driven in particular by large cattle ranchers and farmers, but also small-scale agriculture. New roads promote timber extraction and clearing. With an international team of researchers from the University of Freiburg, the Humboldt University in Berlin and the Institute of Applied Economic Research (IPEA) in Brazil, Börner studied around 15,000 forest law violations across the Brazilian part of the Amazon basin to measure how effective the implementation of the rainforest protection was. "Forest law enforcement is, in principle, similar to speed limit control in traffic: the higher the penalties and the more frequent the controls, the greater the deterrence potential", explains Börner.
...The study suggests that effective rainforest protection hinges on the physical presence of regulators and the actual delivery of disincentives on the ground. This often involves effective collaboration between enforcement authorities at federal and state levels. Based on those criteria, forest law enforcement was particularly effective in the Brazilian states of Mato Grosso and Pará. "Public prosecutors in these states have dramatically increased the pressure: They maintain black lists of agricultural enterprises that violate the protective provisions", reports the ZEF scientist. "For example, wholesale dealers may then no longer buy products from these sources."...
