Governments and proponents of development are increasingly turning to compensatory mechanisms, such as offsets, to counterbalance unavoidable biodiversity and ecosystem service impacts from development. Biodiversity offsetting is perhaps the most well-known compensatory approach, which involves counterbalancing a loss of biodiversity from a development impact with an equivalent biodiversity gain. However, compensatory conservation spans a broader range of approaches, such as payment into conservation funds and support for underfunded protected areas. Compensatory approaches remain controversial, and the science of sound offsets lags far behind their adoption. Our research aims to interrogate, interpret and improve compensatory approaches to conservation. We work with governments, industry, local communities and international convening bodies to formulate and review policy, identify and develop ways to ameliorate risks, and boost public and policymaker capacity to engage with offsets and compensatory conservation.
