Comment: Stop the misuse of biodiversity offsets NATURE Embargo London: Wednesday 22 July 2015 18:00 (BST) New York: Wednesday 22 July 2015 13:00 (EDT) Tokyo: Thursday 23 July 2015 02:00 (JST) Sydney: Thursday 23 July 2015 03:00 (AEST) Governments should not be using the compensation that developers pay for damaging biodiversity to meet existing conservation targets, argue Martine Maron, James Watson and colleagues in aNature Comment piece. Governments are increasingly realising that money generated by offsets could be used to achieve existing conservation commitments. For instance, developers of a copper mine in Panama’s Mesoamerican Biological Corridor will contribute to the costs of managing two existing national parks and a new protected area nearby to compensate for the loss of forest. The Panamanian government can list these parks when reporting progress toward the country’s previously agreed conservation targets without having to declare the damage to biodiversity caused by the mine. A draft report by the International Union for Conservation of Nature (IUCN) on biodiversity offsetting is expected in October. Maron, Watson and co-authors say that it is crucial that the IUCN provides “clear rules on the use of offsetting”. They recommend that future international conservation agreements explicitly require separate accounting of protected-area outcomes achieved through offsets. If governments “renege on their existing commitments by stealth,” offsets could “cause more harm than good,” conclude the authors. In another Comment piece, Andrew Skidmore, Nathalie Pettorelli and colleagues call on ecologists and space agencies to collaborate on a global strategy for monitoring Earth’s biodiversity from space. Currently, different countries track different biodiversity variables, such as habitat types and ecosystem functions, inconsistently. The authors propose quantities, such as vegetation height and leaf area, that can be derived consistently from satellite data and used to monitor deforestation and biodiversity loss across the globe.
