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.

Martine Maron: I am Associate Professor of Environmental Management and an ARC Future Fellow at The University of Queensland, as well as Deputy Director of the Threatened Species Recovery Hub. My fellowship research focusses on biodiversity offsets, exploring the long-term biodiversity consequences (both intended and unintended) of current offset approaches in order to test how they influence the long-term persistence of biodiversity, as well as examining the risks and consequences of the introduction of offsetting into the conservation policy mix at national and international levels.
Nicole Shumway (PhD candidate): Biodiversity offsets are increasingly being used as a mechanism to mitigate impacts from economic expansion and development on species and ecosystems. Marine offset development has lagged behind terrestrial offsets, despite a global increase in marine development and exploitation. The aim of my thesis is to advance both the theoretical and practical basis for marine biodiversity offsets, and to investigate how offsets can be used to minimize impacts on the marine environment and more effectively achieve no net loss of biodiversity.
