Biodiversity offsetting is off-putting

5 11 2018

Ancient-woodland-has-movedBiodiversity offsets are becoming more popular in Australia and elsewhere as a means to raise money for conservation and restoration while simultaneously promoting economic development (1). However, there are many perverse consequences for biodiversity if they are not set up carefully (1-3).

Biodiversity ‘offsets’ are intended to work in a similar way to carbon offsets1, in that the destruction of a part of an ecosystem (e.g., a native forest or grassland, or a wetland) can be offset by paying to fund the restoration of another, similar ecosystem elsewhere. As such, approval to clear native vegetation usually comes with financial and other conditions.

But there are several problems with biodiversity offsetting, including the inconvenient fact that creating an equivalent ecosystem somewhere takes substantially longer than it does to destroy one somewhere else (e.g., 4). While carbon emitted in one place is essentially the same as that sequestered elsewhere, a forest can take hundreds of years to develop the same biodiversity values and ecological functions it had prior to destruction.

South Australia’s broken biodiversity legislation

24 09 2018

It might come as a bit of shock to some who might give more than a shit about our State’s environmental integrity that there is no dedicated legislation to protect biodiversity in South Australia today.

What? Well, ok, we do have the Native Vegetation Act that is supposed to restrict the clearing of existing native vegetation (of which there is precious little left), and the National Parks and Wildlife Act 1972 to legislate protected areas and species endangerment. We also have the Wilderness Protection Act 1992 that addresses wilderness protection and land restoration, and the Natural Resource Management Act 2004 that is designed to promote sustainable and integrated management of the State’s natural resources. Finally, the South Australia Environment Protection Authority operates under various acts1 to limit environmental damage.

However, South Australia has no act specifically focussed on biodiversity conservation, and the legislation that does exist does not even consider invertebrates (like insects) as animals — because most animals are in fact invertebrates, this means that most of South Australia’s species are ineligible for official threat listing, even if they have a high risk of extinction.

If you recall, I reported in July this year that in 2017 we had a Parliamentary Inquiry into Biodiversity2, which concluded that existing environmental legislation in South Australia “… lacks cohesion and consistency, particularly regarding enforcement and compliance provisions”.

In my judgement, therefore, an entirely new, biodiversity-focussed act would add legislative teeth to biodiversity conservation in South Australia. As it turns out, that very same Parliamentary Inquiry into Biodiversity I mentioned above recommended3 the creation of a Biodiversity Expert Panel to reform the legislative framework of environmental protection. Thus, the new Government of South Australia has the perfect opportunity to do so under their proposed changes to natural resource management legislation. Following these calls for reform and the new direction of Nature of SA, there is a real opportunity here for statutory reform that includes integrated biodiversity legislation analogous to the New South Wales Biodiversity Conservation Act 2016.

South Australia doesn’t value its environment

5 09 2018

how we treat our environmentThe South Australian State Budget was released yesterday, and as has been the trend for the last ten years or so, the numbers are not good for the State’s environment.

While it has been reported that the budget includes the loss of 115 full-time staff from the Department of Environment and Water, the overall cuts run much deeper. They also herald a new era of not giving a tinker’s cuss for the sorry state of our environment.

I took the liberty of amassing the budget data with respect to environmental spending in this State since 2002-2003 (the earliest year I could find budget papers), and now I’ve just added the 2018-2019 data.

If I’ve selected the appropriate amounts, — side note: someone desperately needs to teach these budget bean-counters how to standardise, report, itemise, and organise data much, much better than they do (my first-year students could do a better job drunk and blindfolded) — then this is what environmental spending (including environment, biodiversity, water, and the Environment Protection Authority) has looked like since 2002: Read the rest of this entry »
