A biodiversity offset accounting system

Improving the estimation of ecological equivalence within offset exchanges Key messages: Ecologically robust, user-friendly decision support tools improve the transparency of biodiversity offsetting and assist in the decision making process We developed a disaggregated accounting model to balance biodiversity trades within a ‘no-net-loss’ framework The model improves on other models that use aggregated metrics by […]

Offset policies don’t work

So maybe we should be weighing up the alternatives Biodiversity offsetting policies are in place across Australia, administered by both state and federal authorities, to ensure that there are no net losses of native vegetation. Readers might be alarmed then to learn that in 2014, almost 300,000 hectares of native vegetation was cleared in Queensland. […]

threatened legless lizard - and it’s up for proposed development. James (on the right) is explaining to

And the importance of scientific advocacy in shaping long-term policy Everyone wants to influence policy to protect those values they care most about. However, everyone goes about ‘influencing’ in different ways. So far in this series on ‘influencing policy’ we have heard views from a psychology researcher, a research policy officer, an NGO science manager […]

Step forward then look back

Using ‘backcasting’ to improve conservation and offsets policy Understanding the long-term impacts of different conservation policies is a massive challenge. For starters, there are long delays (potentially decades) between policy implementation and the resulting conservation gains or losses. And sometimes measuring those gains or losses can be difficult or even impossible because it’s expensive to […]

Out on a limb: Most people would support funding being made
available to community groups to restore habitat for threatened
species like the Carnaby’s cockatoo. But what if that funding is part
of an offset for habitat loss. Suddenly it’s not about adding value to
environment so much as allowing the loss of equivalent environmental
value. (Photo by Leonie Valentine)

Could well-designed offset policies actually increase loss?

Perverse incentives may yield unintended biodiversity outcomes The idea of biodiversity offsetting is that impacts on biodiversity from development are compensated for by actions elsewhere in the landscape. It’s a simple idea but one that is generating a lot of controversy. Despite the noble-sounding goal of ‘no net loss’ of biodiversity, many are sceptical about […]

Offsetting in the context of policy

What happens to the theory when it hits the real world? Biodiversity offsetting is a highly topical and increasingly popular approach used to compensate for impacts on species and ecosystems as a result of development, and is the subject of a large and growing body of scientific research. There has been substantial work in developing […]

Developing an environmental offsets policy 

Environmental offsetting involves compensating for the residual adverse impacts of an action on the environment by generating an equivalent benefit elsewhere. As the prevalence of environmental offsetting grows, so does the challenge of translating no-net-loss goals to workable policy. From 2011–2012, the Australian Government developed an Environmental Offsets Policy and an accompanying metric (the Offsets […]

Tackling the moving-target problem

Using biodiversity offsets to capture moving conservation targets How do we conserve something when it won’t stand still? It’s a question we are only just beginning to grapple with in conservation science. Fixed protected areas are an example of a classic conservation tool, but traditional interventions like these can be ineffective for ‘moving targets’: for […]
