Protected areas, like national parks and wildlife refuges, are the cornerstones of global conservation efforts. So making sure they achieve their mission is fundamental to our goal of halting biodiversity declines.

Unfortunately, how well protected areas maintain their biodiversity remains poorly understood. While there is clear evidence that protected areas, such as Egmont National Park in New Zealand, can prevent deforestation, there is much less evidence of how well they protect our wildlife.

Our work, published in the journal Nature Communications, examined trends for more than 500 species of birds and mammals in protected areas in 72 countries. The good news is that most animals are doing well, more so for birds than mammals. But that’s no reason to become complacent.

On the whole, birds are doing better than mammals, and species in Europe better than those in Africa. Species doing well include hippopotamus, northern hairy-nose wombats and waterfowl across Europe such as flamingoes in the Camargue region of France.

Those declining in protected areas include bushbuck in Selous National Park and other antelope like kob. Common birds such as common teal and European skylark are not immune, nor are a number of shorebirds globally. Tonkin snub-nosed monkeys are declining in Na Hang National Park in Vietnam, Tucuman parrots in Argentina, and the delightful mallee emu-wren declined to precipitously low levels in Ngarkat National Park, before being wiped out in South Australia in a single fire.

As a result of this monitoring data, many of the declining populations we studied have now been targeted for management – for instance, wetland birds across Europe. Others, like shorebirds, are faced with an intimidating cocktail of hard-to-manage international threats.

A few surprises

Unexpectedly, we also found the biggest animals were doing the best. Species like giraffes and zebras have more positive populations than smaller species like jackals.

This is surprising since larger animals tend to be slow to grow, mature and reproduce. As a result they are often slow to recover from population suppression.

Large animals often act as flagships for particular ecosystems. For instance, orang-utans are a flagship for Indonesia’s rainforests. The implication of our research is that focusing on these species is not enough to make sure all species will survive.

While more than half of protected areas we studied are getting better, there remain many protected areas where declines are still occurring worldwide. Despite this, conditions that deliver success for wildlife in protected areas are poorly understood. So, we investigated which parks were doing best and why.

Wildlife in protected areas is going better in wealthier, more developed countries (Europe) compared to developing countries (like in West Africa). It is hard to tell, though, if the difference is due to more resources available in developed countries, or increasing threats in developing nations.

National-scale socioeconomic conditions were also far more important in influencing how well parks protect wildlife than factors such as size, design or type. This shows it’s important to tailor management to social and political conditions. Over long timescales, the design of protected areas is likely to remain important, but our results show the importance of managing parks for more immediate threats.

Our results suggest that active management – like managing invasive predators, preventing poaching and reducing conflict between people and wildlife – helps animals with low reproductive rates and mitigates the greater threat faced by larger species of birds and mammals due to their slow reproductive rates. Parks still need to be well-managed, though, and threats can’t become too severe – as in the recent poaching crisis.

The tools to ensure good outcomes from protected areas exist — but the will and capacity to implement them must be strengthened if we expect them to act as refuges for all species forever.

This week at the World Conservation Congress, members of the International Union for the Conservation of Nature and NGOs will vote on policies to halt biodiversity declines by 2020. To date, conservationists have focused on increasing the size of the global protected area estate, but simply establishing more protected areas is not enough.

Instead, we need a radical change in commitment. To do this we need to address shortfalls in management. Ensuring both sufficient and secure finances for management and appropriate and equitable governance is just the beginning. Otherwise we’ll keep creating more parks, but wildlife will keep declining.

The autumnal touch of morning mist reveals the fact that spiders are more numerous than we imagine.

Climate scientist and economist publish minority report calling for full emissions trading scheme and closure of brown-coal-fired power plants

The Climate Change Authority’s latest report is a “recipe for further delay” on climate change, contravenes the authority’s legal obligations and recommends “a dog’s breakfast” of policies, say two key members in a dissenting minority report.

Climate scientist David Karoly and economist Clive Hamilton said they could not “in good conscience” put their name to the majority report, which they said privileged “political feasibility” over environmental effectiveness and economic efficiency.

The Climate Change Authority's latest report has divided its membership. Shutterstock.com

As Members of the Climate Change Authority who have participated fully in the Special Review of Australia’s Climate Goals and Policies, we reached the conclusion, after much consideration, that we could not in good conscience lend our names to its report, published last week.

Rather than resign from the Authority we decided to write a minority report. Here we present edited extracts from our report, which is released today.

The basis of our disagreement with the majority report is its failure to recognise the importance of the constraint put on all future emissions-reduction targets and policies by Australia’s carbon budget. The carbon budget is the total emissions that Australia can release between now and 2050 while still contributing its fair share in holding the global temperature rise to less than 2℃ – a key goal of the Paris climate agreement negotiated last December.

The majority report should, but does not, address the relationship between its recommendations and Australia’s carbon budget, consistent with a fair and equitable national contribution to the global carbon budget.

This is all the more regrettable because the requirement to do so is embedded in the Special Review’s terms of reference and was analysed in the First Report of the Special Review released in April 2015 (before the appointment of six new Members to the Authority in October 2015).

The budget constraint

In 2014 the Authority recommended an Australian emissions budget of 10.1 billion tonnes of greenhouse gases for the period 2013-2050. On this basis, it advised that Australia should set an emissions-reduction trajectory for 2030 in the range of 45-65% below 2005 levels. Contrast that with the current 26-28% target set by the Abbott government.

Against the constraints of the carbon budget, the majority report accepts – explicitly in some places, implicitly in others – the government’s current target.

But accepting this less ambitious target for 2030 is consistent neither with the Authority’s own advice to government, nor with Australia’s commitment under the Paris Agreement to play its role in holding warming below 2℃.

The graph below shows the carbon budget for Australia put forward by the Climate Change Authority in its earlier report. (The budget is the area under the curve.)

The embedded pie chart shows the sliver of emissions that would remain to cover the 20-year period after 2030 if there is no change from the 26-28% target. More than 90% of Australia’s carbon budget to 2050 would be used up by 2030. Australia’s emissions would have to decline precipitously and reach net zero by 2035.

Such a dramatic reduction would be impossible to achieve. So the current target of 26-28% lacks credibility because it is wholly inconsistent with Australia’s international obligations. If pursued it is likely to lead to a policy crisis within a decade or less.

Political independence

In our view, the failure of the majority report to make this clear to government and the public contravenes the Authority’s legislated obligation to deliver independent advice and to recommend measures that are “environmentally effective” and based on science.

We believe that the effect of the majority report will be to sanction further delay and a slow pace of action, with serious consequences for the nation. Those consequences include either very severe and costly emissions cuts in the mid-to-late 2020s, or alternatively a repudiation of Australia’s international commitments, and free-riding on the efforts of the rest of the world.

As we see it, the recommendations of the majority report are framed to suit a particular assessment of the prevailing political circumstances. We believe it is inappropriate and often counterproductive to attempt to second-guess political negotiations, especially for a new and uncertain parliament.

The unduly narrow focus of the majority report, seemingly based on a reading from a political crystal ball, has ruled out policies, such as a strengthened renewables target and stronger land clearing restrictions, that have a proven capacity to respond most effectively to the nation’s climate change goals.

Policy recommendations

At the centre of the majority report’s recommendations is the retention of the current Direct Action policy as the basis for further action. Its two pillars are the Emissions Reduction Fund (ERF) and its incorporated Safeguard Mechanism, which sets an upper limit on emissions from major polluters.

The report also recommends a new emissions trading scheme for electricity generation, based on an emissions-intensity baseline. Such a scheme would have lower price rises than the kind of cap-and-trade scheme favoured everywhere else in the world, and which Australia would have now if not for the Abbott government. After the rancour that engulfed the carbon price, the intensity-based scheme is presumably seen as more appealing to nervous politicians.

The majority report downplays the drawbacks of emissions-intensity schemes and the Safeguard Mechanism. There is not space to discuss them here, but we would like to comment on the flaws in the ERF because the majority report recommends that it be hugely expanded.

Flaws in the ERF

Under an expanded ERF policy, the cost to the federal budget would increase sharply, and even more so if Australia adopted tougher emissions targets in line with the science. Using the ERF in this way would be, in Professor Ross Garnaut’s words, “an immense drain on the budget”.

We believe it is unwise to make Australia’s climate policy hostage to disputes over fiscal policy.

As a rule, the replacement of the widely accepted “polluter pays” principle with the ERF’s “pay the polluter” principle is bad economics, bad ethics and bad policy. The practical drawbacks include the need for an expert bureaucracy to evaluate each prospective project and then to monitor, over several years, each successful project to ensure that the promised emissions reductions actually happen.

There are also serious and continuing concerns about the issue of “additionality”. Under the ERF, it is hard to know whether the Commonwealth is wasting money by paying for emissions reductions that would have taken place anyway – that is, projects that are not additional. Bear in mind that businesses plan energy-saving projects all the time, so why wouldn’t they try to get a subsidy if one is on offer?

Surveys show that a large majority of Australians want stronger action to reduce Australia’s emissions. The role of the Climate Change Authority is to advise on how that desire can be realised, in a way that is consistent with the best scientific and economic evidence.
