How much international media attention will it take to get direct action and protect the Great Barrier Reef?

By Dr Anthony Horton

The current controversy involving Ellen DeGeneres and Australian Minister for the Environment Greg Hunt is certainly not the first time (and probably won’t be the last) that someone with an international media profile has pointed out the need for the Australian Government to do everything it can to protect the Great Barrier Reef. In an address to an enthusiastic audience at the University of Queensland in November 2014, United States President Barack Obama pointedly remarked that he wanted his daughters to be able to enjoy the Great Barrier Reef and one day bring their own children to see it. On April 24 this year, a documentary filmed by the world’s most renowned naturalist Sir David Attenborough was aired on ABC Television, highlighting how the Great Barrier Reef was created and showcasing the multitude of creatures that call it home. Following the extensive social media coverage of Ellen DeGeneres’ comments, I was left pondering: how much international media attention will it take to get direct action to protect the Great Barrier Reef after the Federal election on July 2?

The Great Barrier Reef is not only an important ecosystem we need to protect for the benefit of people living in Australia, it is also critically important on an international scale. On the Australian Government Department of the Environment website, the Great Barrier Reef is described as ‘the world’s most extensive coral reef ecosystem’ and ‘a globally outstanding and significant entity’. The website also points out that ‘practically the whole ecosystem was inscribed as World Heritage in 1981’. Such a listing reinforces that the reef must be afforded protection from inappropriate development. The legislative instruments in place to facilitate protection of the Great Barrier Reef are The Great Barrier Reef Marine Park Act 1975 (amended in 2007 and 2008) and the Environment Protection and Biodiversity Conservation Act 1999.

Covering an area of approximately 350,000 km2, the Great Barrier Reef is one of the most diverse natural ecosystems on Earth. Nearly 2 million visitors are drawn to it each year – sustaining more than 60,000 jobs and annually contributing $5 billion to the Australian economy. While the Great Barrier Reef commands respect from environmental, social and economic perspectives, for the purposes of this article I am focusing on the environmental protections the Great Barrier Reef provides the coastline it borders.

As an Australian scientist working in the climate change space at this critical point in time for the environment, I am very happy that DeGeneres has drawn attention to the plight of the Great Barrier Reef

On 8 June 2016, Ellen DeGeneres filmed a video message stating: “It’s critical that we protect this amazing place, and we’d like your help”, referring to the website ‘Remember the Reef’ established by the Disney Conservation and its partners to help preserve the Great Barrier Reef. As an Australian scientist working in the climate change space at this critical point in time for the environment, I am very happy that DeGeneres has drawn attention to the plight of the Great Barrier Reef and the importance of its conservation, particularly during the current Australian election campaign – a campaign in which environmental issues (much less climate change) have been afforded so little discussion to date.

In response, Australian Government Minister for the Environment Greg Hunt sent DeGeneres numerous tweets defending the Government and what it has done to help the reef so far. Channel 9 Today Show co-host Karl Stefanovic also added to the discussion on June 9 by stating his concern was that “she has got involved in that around the whole notion of selling a movie anyway” – in reference to the upcoming movie release of ‘Finding Dory’ in which Ellen DeGeneres voices the main character. Rather than focus on who said what on twitter, my intention is to discuss why efforts to protect the Great Barrier Reef should be strengthened; supporting the need for us to protect the reef itself and the creatures that call it home, and to ensure that the valuable protective services it provides the coastline which it borders are maintained.

According to the ‘Managing Coasts with Natural Solutions’ report published in January this year by the World Bank Group Accounting and Valuation of Ecosystem Services (WAVES) program, coral reefs:

  • Provide natural protection from flooding and erosion by reducing and dispersing wave energy by up to 97%
  • Supply and trap sediment found on beaches
  • Produce carbonates as they grow and, if they remain healthy, could require minimal maintenance funding in order to continue to protect coastlines

In the United States, the Federal Emergency Management Authority (FEMA) spends $500 million each year to reduce flooding hazards. Brazil, China and Columbia are spending billions of dollars addressing the risks of flooding and other climate change related disasters. The majority of these funds are being spent on the construction of infrastructure such as seawalls. The Great Barrier Reef provides this range of protective services mentioned above to the significant section of Australian coastline that it borders. And yet, in Australia we rarely (if ever) hear a discussion of how important these services are. It would be a great shame if these significant benefits were ignored, only to be discussed once the Great Barrier Reef has passed the point of no return and the coastline it borders is under threat from flooding and/or erosion – events that would result in significant environmental and financial costs.

A range of scientific disciplines play important parts in valuing the Great Barrier Reef. Understanding local climate patterns, chemical transport/cycling, as well as its structural integrity are critical to placing a realistic value on the reef. According to the WAVES program report, process-based approaches are the best for valuing the coastal protection services that coral reefs provide. These process-based approaches use variables including storm surges, currents, sediment transport, and interactions between waves and structures to assess risks as well as measure the value of habitats in reducing flooding and other climate change related disasters. The report outlines five steps for estimating the benefits that coral reefs provide:

  1. Estimating offshore hydrodynamics

In order to estimate offshore dynamics, it is important to first understand the oceanographic conditions that generate waves from wind in deep waters. An assessment of wind, waves, mean sea level, tides and storm surge is critical to understanding offshore hydrodynamics. The average and extreme offshore conditions for each of these variables must be gauged in order to understanding the range of conditions reefs are exposed to over a full year of four seasons. It is only once the full range of conditions are understood that appropriate reef management strategies can be implemented

  1. Estimating nearshore hydrodynamics

Waves change as they travel from deep to shallow water as a result of the local bathymetry (e.g. depth profile) and coastal morphology (structural features). In nearshore environments, waves undergo refraction, dissipation, diffraction and other sources of energy transfer. Characterising nearshore wave height and energy is an important part of estimating nearshore dynamics, and is in turn important to understanding how the reef protects the coastline that it borders

  1. Estimating the effects of coastal habitat on hydrodynamics

Nearshore waves interact with habitats and other structures that attenuate (e.g. weaken) the waves and thereby reduce their energy. Coral reefs attenuate short waves (e.g. wind waves) as the waves break on them. Similar to the previous point, understanding wave attenuation is important to understanding the extent of the protection that a reef affords its immediate and near coastline

  1. Estimating flooding

After waves pass over reef habitats, any remaining wave energy creates onshore flooding or erosion. A key part of assessing the risk of flooding is understanding the frequency of storms in the area. Following an assessment of the storm frequency, it is important to understand topographic elevation as lower lying areas will be more susceptible to flooding. The dimensions of the low lying area in which flooding occurs is defined as the ‘flooding envelope’

  1. Assessing expected and averted damages

Assessing these damages involves calculating the number of people and assets within a flooding envelope. Once this is known, a damage function that describes the likely value of assets flooded under different storm frequencies (e.g. one in 10, and one in 100 year events) can be derived. Once this is derived, the difference in damages with and without coral reefs can be calculated

By now you’re probably asking yourself what the Australian Labor Party and the current Government have pledged to do to protect the Great Barrier Reef. On 31 May 2016 the Australian Labor Party (ALP) announced that an ALP Government would allocate $500 million to protect the Great Barrier Reef through better research, co-ordination and environmental programs. Of this $500 million, $100 million would be spent by the Commonwealth Scientific and Industrial Research Organisation (CSIRO), $300 million would be spent on programs to reduce nitrogen and sediment run- off, and the remaining $100 million would be spent on improving the management of the Great Barrier Reef. Yesterday (13 June 2016) the current Australian Government announced a $1 billion Reef fund that will provide concessional loans for clean energy projects that will reduce pollutant and fertiliser run-off and limit discharge from sewage treatment plants to the ocean thereby improving water quality. This $1 billion will come from the $10 billion fund administered by the Clean Energy Finance Corporation to facilitate investment in renewable energy projects in Australia.

Those of you who read my articles will know that I support renewable energy as one part of a cleaner future. You will also know that I have written a number of articles on the status of renewable energy investment in Australia compared to the international market. I want to be very clear here – funding the protection of the Great Barrier Reef using funding intended for Australian renewable energy projects is surely at cross purposes.

The Australian renewable energy sector needs as much funding as it can reasonably get in order to grow and sustain itself and the livelihoods of those who depend on it for employment. The protection of the Great Barrier Reef also needs as much funding as possible to ensure its endurance against the realities of climate change. The renewable energy sector and the Great Barrier Reef should not be in competition for Government funding – which is effectively what will happen under the current Government’s announcement. Funding for the protection of the Great Barrier Reef should come from a clearly differentiated source other than from the allocated funding for renewable energy projects in Australia.

As sea levels continue to rise, it stands to reason that recognising the value of the Great Barrier Reef is essential

The conservation of the Great Barrier Reef must be given the highest priority and afforded the highest level of protection by the Australian Government as a first line of defence against storms, flooding, rising sea levels and other extreme weather events which can cause hundreds of millions or billions of dollars worth of damage, threatening people’s lives and livelihoods. As sea levels continue to rise, it stands to reason that recognising the value of the Great Barrier Reef is essential to the protection of coastal communities.

In reviewing the social media coverage of the comments made by Ellen DeGeneres, Barack Obama and Sir David Attenborough, and after reading the ‘Managing Coasts with Natural Solutions’ report, I implore you the reader to join me in demanding that the Australian Government appropriately values the Great Barrier Reef for the protection it provides coastal areas, for the habitats it provides for the marine life that rely on it, and for the billions of dollars in injects into the Australian economy through employment and tourism.

Post the double dissolution election scheduled for 2 July 2016, regardless of whether the current Government is returned or the ALP wins the Federal election, one thing is very clear – the eyes of the world will be on what the Australian Government does to protect the Great Barrier Reef. As the Ellen DeGeneres controversy demonstrates, a global audience (Australian voters included) are now wondering how much international media attention it will take to get direct action to protect the Great Barrier Reef.

The Australian Government would do well to take heed of Ellen DeGeneres’s call to protect the Great Barrier Reef

One of Minister Hunt’s tweets to Ellen DeGeneres on June 8 really struck a chord with me. Part of his message states that “We all have a role and the Aust govt is doing more than ever to protect it”. I think many Australians would disagree with this statement, as I do along with my colleagues and other scientists in the environmental space. We argue instead that the Government is doing is still not enough to ensure the long-term survival and prosperity of the Great Barrier Reef. I absolutely agree with DeGeneres’s comment as reported by 9news.com.au that “we should protect our oceans and protect the reef, and I don’t know what’s controversial about that”. It is a truly sad day when we cannot express our concern for an environmental issue that we consider important – this is just what Ellen did, and I for one applaud her for it. I believe that the Australian Government would do well to take heed of Ellen DeGeneres’s call to protect the Great Barrier Reef rather than be critical of it.

    Unknown … this current government is impervious to any kind of criticism or condemnation … but. on the brighter side, do respond to bribery … that may possibly do the trick.

    sorry to be such a cynic but: “Finding Dory” isn’t just about a little blue fish looking for a home. The long-awaited sequel to “Finding Nemo ” also reflects the journey of the woman behind the gills, Ellen DeGeneres’. She is the voice of Nemo and the sequel just happens to be coming out now.

    Can`t tell me that 200 million gallons or 757 million liters of crude oil spilled out into the ocean from BP had no long term effect on reefs all around the globe just to name one spill. Who could even guess how many chemicals are dumped or washed into the oceans from every country around the world.. It has to slowly change the PH levels and chemical make up.It is not just Australians killing the reef..

  4. Stephen Brailey

    You’re entirely right Anthony our government needs to spend substantial sums and right now. Might I suggest a good first step would be the compulsory squisition and revegetation of all riparian vegetation along streams and rivers leading into the GBR! Because to many of the clowns who live up here think the whole things a big joke. Thère is still sand mining IN the river systems leading inyo the GBR. Some local groups have done great work but in other regions surrounded by sugar cane or bananas waterways are just eroded weed choked cane toad breeding zones.

    Perhaps it’s time to just give up and let the politicians have their own way.

    A dead reef would have just as much value to the world by being an example of the consequences of placing political and business self-interest above everything else and would be there for all to see.

    It may be a smaller price to pay for the sake of future generations than a potential and perhaps inevitable global catastrophe if we continue in the same denialist way.

    ‘How much international media attention will it take to get direct action and protect the Great Barrier Reef?’ Since the time of the Rudd Gillard government international media attention critical of the policies of Australian governments (of either persuasion) has been ignored/dismissed by the government in question. The three hot points for such ‘attention’ have been environment/global warming, asylum seekers, gay rights. The response to regular (international or local) media criticism in these spaces has typically been: ‘They are wrong. Our policies are just and/or effective and/or necessary.’ End of story. Thus the vague disquiet of the nation is alleviated and it slumbers on with the issues un-addressed.

    The fate of the Great Barrier Reef, and most, if not all other tropical coral reefs, is already sealed as the following quote from a recent Climate Code Red post indicates.

    “In 2009, Australian scientists contributed to an important research paper, ‘Limiting global warming to 2 °C is unlikely to save most coral reefs’, which found that preserving more than 10% of coral reefs worldwide would require limiting warming to below 1.5°C.
    On the 6 July 2009, the Royal Society, the Zoological Society of London and the International Programme on the State of the Ocean facilitated a Coral Reef Crisis meeting to identify key thresholds of atmospheric carbon dioxide needed for coral reefs to remain viable. It concluded that:
    ‘To ensure the long‐term viability of coral reefs the atmospheric CO2 level must be reduced significantly below 350 parts per million carbon (ppm). In addition to major reductions in CO2 emissions, achieving this safe level will require the active removal of CO2 from the atmosphere.’
    Pioneer Australian coral researcher Charlie Veron told that meeting: ‘The safe level of atmospheric carbon dioxide for coral reefs is ~320 ppm (and) sets the safe limit for a healthy planet during a time of abrupt greenhouse-driven climate change.’ Today’s level is 400 ppm and rising.”

    The world has now almost certainly overshot the 2ºC warming threshold that the most optimistic policy makers continue to talk about – and remember that this gave only a 50/50 chance of avoiding runaway warming. The result of all this is the (almost certainly inevitable) demise of the reefs. The implications of this goes far beyond the loss of tourist dollars to the Australian economy (Climate Code Red again):

    “Coral reefs provide food and resources for over 500 million people along tropical coastlines, as well as coastal protection against storm surges. If the world’s coral systems are lost, coastal ecosystems will only be able to provide 20–50% of the fish protein that they do today for those half a billion people. Australia’s neighbours are particularly vulnerable.”

    The implications for Australia of this drastic reduction in available food along the Indian and Pacific Ocean coasts of our neighbours are self evident and troubling. Of course we must do what is necessary to reduce the environmental stress and improve the health of our reefs (thus prolonging their existence) but according to the relevant scientific expertise, locked in warming and the accompanying ocean acidification, means that, sooner or later, they will almost certainly be destroyed. What we are really talking about is when.

    Clown Fish ultra right wing politician Greg Hunt acting as an Federal Environment Minister in Canberra like Pauline Hanson has got it wrong. I would rather believe David Attenborough than centre right or ultra centre right politician in Canberra or Brisbane (Brisvegas) where state parliament is in Queensland. These persons are low as the nz all blacks rugby team with the way they cheat and bully other teams in Rugby.The mining companies should be exporting out of Weipa QLD rather than the great barrier reef for starters on the north east part of QLD.
