The following is a statement from the Ocean Science Council of Australia, an internationally recognised independent group of university-based Australian marine researchers, and signed by 1,286 researchers from 45 countries and jurisdictions, in response to the federal government’s draft marine parks plans.

We, the undersigned scientists, are deeply concerned about the future of the Australian Marine Parks Network and the apparent abandoning of science-based policy by the Australian government.

On July 21, 2017, the Australian government released draft management plans that recommend how the Marine Parks Network should be managed. These plans are deeply flawed from a science perspective.

Of particular concern to scientists is the government’s proposal to significantly reduce high-level or “no-take” protection (Marine National Park Zone IUCN II), replacing it with partial protection (Habitat Protection Zone IUCN IV), the benefits of which are at best modest but more generally have been shown to be inadequate.

The 2012 expansion of Australia’s Marine Parks Network was a major step forward in the conservation of marine biodiversity, providing protection to habitats and ecological processes critical to marine life. However, there were flaws in the location of the parks and their planned protection levels, with barely 3% of the continental shelf, the area subject to greatest human use, afforded high-level protection status, and most of that of residual importance to biodiversity.

The government’s 2013 Review of the Australian Marine Parks Network had the potential to address these flaws and strengthen protection. However, the draft management plans have proposed severe reductions in high-level protection of almost 400,000 square kilometres – that is, 46% of the high-level protection in the marine parks established in 2012.

Commercial fishing would be allowed in 80% of the waters within the marine parks, including activities assessed by the government’s own risk assessments as incompatible with conservation. Recreational fishing would occur in 97% of Commonwealth waters up to 100km from the coast, ignoring the evidence documenting the negative impacts of recreational fishing on biodiversity outcomes.

Under the draft plans:

• The Coral Sea Marine Park, which links the iconic Great Barrier Reef Marine Park to the waters of New Caledonia’s Exclusive Economic Zone (also under consideration for protection), has had its Marine National Park Zones (IUCN II) reduced in area by approximately 53% (see map below)

• Six of the largest marine parks have had the area of their Marine National Park Zones IUCN II reduced by between 42% and 73%

• Two marine parks have been entirely stripped of any high-level protection, leaving 16 of the 44 marine parks created in 2012 without any form of Marine National Park IUCN II protection.

The replacement of high-level protection with partial protection is not supported by science. The government’s own economic analyses also indicate that such a reduction in protection offers little more than marginal economic benefits to a very small number of commercial fishery licence-holders.

Retrograde step

This retrograde step by Australia’s government is a matter of both national and international significance. Australia has been a world leader in marine conservation for decades, beginning with the establishment of the Great Barrier Reef Marine Park in the 1970s and its expanded protection in 2004.

At a time when oceans are under increasing pressure from overexploitation, climate change, industrialisation, and plastics and other forms of pollution, building resilience through highly protected Marine National Park IUCN II Zones is well supported by decades of science. This research documents how high-level protection conserves biodiversity, enhances fisheries and assists ecosystem recovery, serving as essential reference areas against which areas that are subject to human activity can be compared to assess impact.

The establishment of a strong backbone of high-level protection within Marine National Park Zones throughout Australia’s Exclusive Economic Zone would be a scientifically based contribution to the protection of intact marine ecosystems globally. Such protection is consistent with the move by many countries, including Chile, France, Kiribati, New Zealand, Russia, the UK and US to establish very large no-take marine reserves. In stark contrast, the implementation of the government’s draft management plans would see Australia become the first nation to retreat on ocean protection.

Australia’s oceans are a global asset, spanning tropical, temperate and Antarctic waters. They support six of the seven known species of marine turtles and more than half of the world’s whale and dolphin species. Australia’s oceans are home to more than 20% of the world’s fish species and are a hotspot of marine endemism. By properly protecting them, Australia will be supporting the maintenance of our global ocean heritage.

The finalisation of the Marine Parks Network remains a remarkable opportunity for the Australian government to strengthen the levels of Marine National Park Zone IUCN II protection and to do so on the back of strong evidence. In contrast, implementation of the government’s retrograde draft management plans undermines ocean resilience and would allow damaging activities to proceed in the absence of proof of impact, ignoring the fact that a lack of evidence does not mean a lack of impact. These draft plans deny the science-based evidence.

We encourage the Australian government to increase the number and area of Marine National Park IUCN II Zones, building on the large body of science that supports such decision-making. This means achieving a target of at least 30% of each marine habitat in these zones, which is supported by Australian and international marine scientists and affirmed by the 2014 World Parks Congress in Sydney and the IUCN Members Assembly at the 2016 World Conservation Congress in Hawaii.

The UK and US reach an agreement that aims to allow freer movement of research equipment and scientists

We should be worried about the flood-proofing of our nuclear power plants, says Sue Roaf, while David Bridgewater argues for nuclear fusion, rather than fission. Plus letters from Dr Kevin Purdy, Dr John Doherty and John Starbuck

In Agneta Rising’s defence of nuclear generation (Letters, 19 September), she claims that nuclear plants have to occasionally stop for repair and maintenance. But jellyfish also get into seawater inlets, as at Torness in 2011, causing week-long shutdowns. Seaweed can block inlets shutting reactors, and operator incompetence shuts reactors and compromises radioactive cores. Torness was even narrowly missed by a crashing RAF Tornado jet. Most worrying are not such transient manageable events but risks of systematic flooding of nuclear sites.

Nine UK plants are assessed by Defra as currently vulnerable to coastal flooding (Report, 7 March 2012), including all eight proposed new UK nuclear sites and numerous radioactive waste stores, operating reactors and defunct nuclear facilities. EDF claims on its website that “to protect the Hinkley Point C station from such events, the platform level of the site is set at 14 metres above sea level, behind a sea wall with a crest level of 13.5 metres”. Hurricane Katrina in 2005 produced a maximum storm surge of 8.5 metres. It is predicted that sea levels may rise by a metre by 2100. The UK government cannot actually have believed in climate change or surely they would not put future generations at such risk?  I bet they believe in it now. The question is: do they care? Is it really too late to stop a retrograde, potentially catastrophic and already unaffordable UK nuclear future?

Our new paper illustrates the rapid, consistent warming of Earth’s oceans

We’ve known for decades that the Earth is warming, but a key question is, how fast? Another key question is whether the warming is primarily caused by human activities. If we can more precisely measure the rate of warming and the natural component, it would be useful for decision makers, legislators, and others to help us adapt and cope. Indeed, added ocean heat content underlies the potential for dangerous intense hurricanes.

An answer to the “how fast?” question was partly answered in an Opinion piece just published on Eos.org, the daily online Earth and space science news site, by scientists from China, Europe and the United States. I was fortunate enough to be part of the research team.

Findings leave researchers hopeful that understanding hearing preservation in birds could lead to new treatment possibilities for deaf humans

If ageing humans had ears like those of barn owls they would never need hearing aids, scientists have shown.

The birds, whose sensitivity to sound helps them locate prey, suffer no hearing loss as they get older. Like other birds – but unlike mammals, including humans – they are able to regenerate cells in their inner ears.

It seems that the one certainty about any clean energy target set by the present government is that it will not drive sufficient progress towards a clean, affordable, reliable energy future. At best, it will provide a safety net to ensure that some cleanish energy supply capacity is built.

Future federal governments will have to expand or complement any target set by this government, which is compromised by its need to pander to its rump. So a cleanish energy target will not provide investment certainty for a carbon-emitting power station unless extraordinary guarantees are provided. These would inevitably be challenged in parliament and in the courts.

Read more: Turnbull is pursuing ‘energy certainty’ but what does that actually mean?

Even then, the unstoppable evolution of our energy system would leave an inflexible baseload power station without a market for much of the electricity it could generate. Instead, we must rely on a cluster of other strategies to do the heavy lifting of driving our energy market forward.

The path forward

It’s clear that consumers large and small are increasingly investing “behind the meter” in renewable energy technology, smart management systems, energy efficiency and energy storage. In so doing, they are buying insurance against future uncertainty, capturing financial benefits, and reducing their climate impacts. They are being helped by a wide range of emerging businesses and new business models, and existing energy businesses that want to survive as the energy revolution rolls on.

The Australian Energy Market Operator (AEMO) is providing critically important information on what’s needed to deliver energy objectives. The recently established Energy Security Board will work to make sure that what’s needed is done – in one way or another. Other recommendations from the Finkel Review are also helping to stabilise the electricity situation.

The recent AEMO/ARENA demand response project and various state-level energy efficiency retailer obligation schemes and renewable energy targets are examples of how important energy solutions can be driven outside the formal National Energy Market. They can bypass the snail-paced progress of reforming the NEM.

States will play a key role

State governments are setting their own renewable energy targets, based on the successful ACT government “contracts for difference” approach, discussed below. Victoria has even employed the architect of the ACT scheme, Simon Corbell. Local governments, groups of businesses and communities are developing consortia to invest in clean energy solutions using similar models.

Some see state-level actions as undermining the national approach and increasing uncertainty. I see them as examples of our multi-layered democratic system at work. Failure at one level provokes action at another.

State-level actions also reflect increasing energy diversity, and the increasing focus on distributed energy solutions. States recognise that they carry responsibilities for energy: indeed, the federal government often tries to blame states for energy failures.

There is increasing action at the network, retail and behind-the-meter levels, driven by business and communities. While national coordination is often desirable, mechanisms other than national government leadership can work to complement national action, to the extent it occurs.

Broader application of the ACT financing model

A key tool will be a shift away from the current RET model to the broader use of variations of the ACT’s contract for difference approach. The present RET model means that project developers depend on both the wholesale electricity price and the price of Large Generation Certificates (LGCs) for revenue. These are increasingly volatile and, over the long term, uncertain. In the past we have seen political interference and low RET targets drive “boom and bust” outcomes.

So, under the present RET model, any project developer faces significant risk, which makes financing more difficult and costly.

The ACT contract for difference approach applies a “market” approach by using a reverse auction, in which rival bidders compete to offer the desired service at lowest cost. It then locks in a stable price for the winners over an agreed period of time.

The approach reduces risk for the project developer, which cuts financing costs. It shifts cost risk (and opportunity) to whoever commits to buy the electricity or other service. The downside risk is fairly small when compared with the insurance of a long-term contract and the opportunity to capture savings if wholesale electricity prices increase.

The ACT government has benefited from this scheme as wholesale prices have risen. It also includes other requirements such as the creation of local jobs. This approach can be applied by agents other than governments, such as the consortium set up by the City of Melbourne.

For business and public sector consumers, the prospect of reasonably stable energy prices, with scope to benefit if wholesale prices rise and limited downside risk, is attractive in a time of uncertainty. For project developers, a stable long-term revenue stream improves project viability.

The approach can also potentially be applied to other aspects of energy service provision, such as demand response, grid stabilisation or energy efficiency. It can also be combined with the traditional “power purchase agreement” model, where the buyer of the energy guarantees a fixed price but the project developer carries the risk and opportunity of market price variations. It can also apply to part of a project’s output, to underpin it.

While sorting out wholesale markets is important, we need to remember that this is just part of the energy bill. Energy waste, network operations, retailing and pricing structures such as high fixed charges must also be addressed. Some useful steps are being taken, but much more work is needed.
