People are 'blind' to plants, and that's bad news for conservation

The Conversation - Wed, 2016-09-14 06:16
Sometimes plants are obvious, but often they slip under the radar Wildflower image from www.shutterstock.com

Turn away from your computer screen for a moment and try to remember what you saw in the image below.

The image has an equal number of plants and animals, but chances are that you remembered more animals than plants. This bias in memory is part of a phenomenon known as “plant blindness”. Research shows that people are also generally more interested in animals than plants, and find it harder to detect images of plants compared with images of animals.

Plant blindness is more than an interesting quirk of human perception. It impacts on our efforts to care for and understand plant species. Figures from the United States show that while most federal endangered species (57%) are plants, less than 4% of money spent on threatened species is used to protect plants. Botanical education has been declared under threat in the UK.

In a recent essay, Mung Balding and I argue that overcoming plant blindness requires more than plant education. Instead we need to help people connect with plants emotionally.

Why does it happen?

We aren’t sure why plant blindness occurs. One theory suggests that because plants generally grow close together, do not move and often blend together visually, they often go unnoticed when animals are present.

Another possibility is that we learn plant blindness. For example, biology textbooks give much less space to plants compared with animals, potentially leaving schoolchildren with the impression that plants don’t matter.

But we also know many societies have strong bonds with plants. Among some Aboriginal Australian, Native North American and Maori communities, plants are understood to be different from humans but also to share a common ancestry that brings kinship relationships of mutual responsibility.

Overall, research suggests that while plant blindness is common, it is not inevitable. Here are three strategies that we believe could make a difference.

Identify with plants

Plants can seem very different from humans. Research has shown that animal conservation support is biased towards species that are most like humans.

Unlike humans and many other animals, plants don’t have faces, don’t usually move locations and don’t seem to have feelings. One way to start valuing plants is to notice ways that we actually are alike.

Science can help us see how plants have similarities with humans. Plants are alive, have sex, communicate and take up food. Some young plants share the root system of their parent plant – a “protective” behaviour that many human parents will recognise.

Rituals are another way of identifying with plants. For example, for people living on the island of Nusa Penida near Bali, the coconut palm is an important plant. Early in a child’s life, the father will plant a tree for the child. The tree’s development and life span then parallels the child’s and in ceremonies it is clothed and presented with food.

Coconut palms are an important part of ritual on some Indonesian islands. Coconut palm image from www.shutterstock.com Empathy with plants

Actively imagining the experiences of plants and animals is another way people can connect with plants. In a psychological experiment, participants were shown images of either a dead bird on a beach, covered in oil, or a group of trees that had been cut down.

Half the participants were told to view the image objectively, while the rest were asked to imagine how the bird or tree felt. The researchers found that people who actively empathised with the bird or tree not only expressed greater concern but also donated more money to protecting the species.

Art, imagination and ritual can all help people to imaginatively empathise with plants. So too can tending plants, as one experiences the joys and sorrows of plant life and death.

Make plants human

A third – and more controversial – way to connect with plants is through anthropomorphism. Anthropomorphism means attributing human characteristics to plants, like describing a drooping plant as sad, or a sunflower as turning its face toward the sun.

Facing the sun: these sunflowers look very happy. Sunflower image from www.shutterstock.com

Anthropomorphism of animals is common in entertainment and conservation campaigns but rarely used for plants. Some writers consider anthropomorphism to be unhelpful: it can misdirect thinking about plants, or sentimentalise plants in ways that belittle them. But experiments show that making or reading anthropomorphic pictures and stories can also help people to empathise with nature and want to act to protect nature.

Want to test this out for yourself? Try a thought experiment by watching this 1932 animation from Walt Disney. The dancing, courting and fighting trees are rather bewildering, but do you feel a twinge of anxiety when the trees are threatened by fire, or relief as the woodland recovers?

Feeling anxious?

Plant conservationists view plants as having value in their own right, so it might seem odd to suggest that we promote plant conservation by thinking about the ways plants are like humans. The strategies we suggest draw on theory that proposes that people are more likely to act in the interests of nature if we think about nature as being part of us. Appreciating our connections with plants may be the best way to begin respecting their amazing differences.

Hugh Boyd obituary

The Guardian - Wed, 2016-09-14 02:59

My friend Hugh Boyd, who has died aged 91, made a massive contribution to wetland and waterbird conservation at world level over six decades.

Hugh was recruited to Peter Scott’s groundbreaking team as the first research biologist at the Severn Wildfowl Trust (now the Wildfowl & Wetlands Trust) at Slimbridge, Gloucestershire, in 1949. Over the next 20 years, Hugh and the team exerted an immense influence encouraging younger ornithologists and developing “citizen science” networks of volunteer counters for annual monitoring of waterbird population sizes.

August ties with July as hottest month on record

The Guardian - Wed, 2016-09-14 00:02

August continued the remarkable streak of record hot months in 2016, equalling July as the hottest month on record

In what has become a common refrain this year, last month ranked as the hottest August on record, according to NASA data released Monday. Not only that, but the month tied July as the hottest month the world has seen in the last 136 years.

August came in at 1.76˚F (0.98˚C) above the average from 1951-1980, 0.16C above August 2014, the previous record holder. The record keeps 2016 on track to be the hottest year in the books by a fair margin.

Australian Renewable Energy Agency saved but with reduced funding – experts react

The Conversation - Tue, 2016-09-13 16:57
Malcolm Turnbull and Bill Shorten have reached a compromise on the Renewable Energy Agency: it will see survive, but with reduced funding. AAP Image/Lukas Coch

The Australian Renewable Energy Agency (ARENA) has been granted a funding lifeline of A$800 million over the next five years, after the federal government and opposition came to an agreement that will save the agency.

ARENA had faced being wound down as a result of the government’s earlier proposal to strip A$1.3 billion from the agency. This was part of a wider package of measures designed to save the federal budget more than A$6 billion.

Renewable energy researchers had reacted with dismay to that proposal. An open letter to the government in defence of the agency attracted 190 signatures.

Below, our experts react to the news.

Nicky Ison, Senior Research Consultant, Institute for Sustainable Futures, University of Technology Sydney

Today the Coalition government and the Labor Party struck a deal to:

  • slash half-a-billion dollars from the Australian Renewable Energy Agency; and

  • save the Australian Renewable Energy Agency (ARENA).

These statements seem like a contradiction, but both are true. However, it is also true that the need to save ARENA exists because of the Coalition government’s efforts over the past three years to dismantle Australia’s renewable energy policy.

If the benchmark is that we keep our existing renewable energy institutions, today was a win. However, if the benchmark is that we have institutions and policies that have sufficient funding and scope to tackle the policy challenges of climate change, our changing energy system and driving innovation, then today was a loss.

Andrew Blakers, Professor of Engineering, Australian National University

The Australian research community is pleased that the government’s proposal to debilitate ARENA by removing A$1.3 billion and ending its granting function will not go ahead. At the same time, we are disappointed that yet again ARENA is subject to huge funding cuts.

The fastest and surest way to reduce greenhouse gas emissions is to accelerate the introduction of renewable energy into the electricity system. ARENA has focused heavily in this area (among others), covering the full gamut from support for early-stage research, through grants to young renewable energy companies, to acceleration of deployment of large-scale solar photovoltaic systems.

ARENA will need to heavily prune its activities to cope with a A$500 million budget cut. We look forward to restoration of ARENA funding, and to a concerted effort at the national level to move rapidly to 50-100% renewable electricity.

Tony Wood, Energy Program Director, Grattan Institute

The silver lining amid the cloud of the political compromise on ARENA funding represents a welcome return to the art of the possible. Of course it is a pity that ARENA has been cut again, given that among Kevin Rudd’s climate change children this one had bipartisan support, at least until the 2014 budget.

Grant funding to drive down the costs of renewable technologies with real potential has been ARENA’s model and the funds now secured will allow this to continue. The next challenge is to create an integrated model that connects grant funding with the recently announced Clean Energy Innovation Fund, which will provide debt and equity funding to emerging renewable technologies, and the Clean Energy Finance Corporation’s role of developing innovative financial models to commercialise clean energy.

Living for another day is never a bad outcome.

Risky business: how companies are getting smart about climate change

The Conversation - Tue, 2016-09-13 15:18
Companies are weighing up whether investment in a coal mine is worth the risk. from www.shutterstock.com

The divestment movement is gaining momentum – and is just one of the emerging risks from climate change that businesses face. The Paris climate agreement not only signalled social change but also sent the market a strong signal to move away from carbon-intensive investment.

The divestment movement may be seen by some businesses invested in fossil fuels as a risk. But it is not the only force shaping how companies address climate change. So, what are some of the other factors in rethinking climate risk?

Evolving social norms

The Paris Agreement recently gained more steam with ratification by the United States and China. This signalled the intent of these leading global economies to commit to helping to limit global warming to 2℃. Achieving this will require a transition to a low-carbon or decarbonised economy. China, for example, has been aware of how important this is since 2008.

Since the launch of the Low Carbon Economy Index by PricewaterhouseCoopers in 2009, companies have been better equipped to understand and measure private sector climate risk. This has flow-on effects to just about all human behaviours, and has had a particularly significant impact on private equity investments.

In particular, pension funds and the insurance sector are among the leading sectors in considering future climate risk within and across their portfolios. This is facilitating evolving social norms around climate change. These changes have long been recognised as critical for climate change mitigation and adaptation.

The role of law

Liability risk remains at the forefront in current trends. The acceptance of legal responsibility demonstrated by global leaders' ratification of the Paris Agreement is all the more interesting when we consider recent developments in climate litigation.

Some argue that, in future, there will be parallels between tobacco and asbestos tort litigation and climate litigation, given that the consequences of a changing climate have been well known for decades, and widely cited by scholars and practitioners alike. It is therefore difficult for a legal entity to claim ignorance of climate risks.

Internationally, a decision in 2015 held Dutch public officials legally accountable in reducing emissions. In the United States, instances of litigation have increasingly focused on companies' disclosure of known future climate risk. Pressure has also been building on Exxon Mobil as evidence emerges that the company may have lied to shareholders about this known risk.

In Australia, some recent interesting developments in coastal planning law are contributing to a more coherent body of climate law.

Fiduciary duties are an important aspect of rethinking climate risk. In law, they can require companies to disclose future risk. A failure to disclose on “the business strategies, and prospects for future financial years” under the Corporations Act may be considered a breach of the law and subject to ASIC enquiry.

While some regulatory guides exist for how to achieve general compliance, recent submissions to the Senate inquiry into carbon risk disclosure have argued that specific regulatory guidance for future climate risk is needed. Arguably, disclosing future risks includes future climate risks to assets and company investments.

The courts are moving where regulation and policy may be slower to act. In April 2016, the New South Wales Supreme Court relaxed the hurdles for shareholders to bring action against a company in a case where an insurer, HIH, led the market to believe it was trading more profitably and had greater net assets than was the case. This artificially inflated the HIH share price, resulting in shareholders suffering a loss because they bought overpriced shares. This case is important for shareholder class actions because it is the first time the court has accepted the principle of indirect market based causation.

In a similar way, a failure to disclose known future climate risk in required disclosure documents could potentially amount to misleading and deceptive conduct. This is particularly the case where companies may fail to disclose their asset exposure to climate change impacts.

Technological risk

The World Economic Forum’s Global Risks Report 2016 noted that the number-one risk to the global economy was a failure to mitigate and adapt to climate change.

Some argue that technological responses, including carbon capture and storage, continue to require research and development input. Others suggest that investing in renewable energy, particularly for developing countries, will lead to more sustainable global outcomes including, importantly, social equity.

While mitigation technologies continue to compete for long-term success, investors need to be increasingly aware of where and how they prioritise their mitigation efforts.

Where to now for Australian companies?

The 2016 carbon risk disclosure inquiry was due to publish its report in June 2016 but lapsed due to the federal election. This Senate inquiry ought to recommence as a matter of priority.

Additional legal mechanisms that will have flow-on effects for evolving social norms and for rethinking climate risk could include legislative change to require the inclusion of reporting asset exposure risks, under the National Greenhouse and Energy Reporting Act.

Climate risk, the transition to a low-carbon economy, evolving social norms and the continued growth of climate law evidence a need to ensure coherence across economic, social and governance frameworks.

Waltham Brooks, West Sussex I’ve seen hobbies hunt smaller birds in fast, level flight, but not attack as a peregrine would

Golden grass heads nod up and down in flowing waves at the insistence of the breeze. Lapwing are collecting around the edges of the pools in greater numbers than before, and there are also more gadwall and mallard paddling on the water as autumn draws in.

Clouds of soft brown and cream sand martins and black and white swallows – hirundines – dance low over the water. They turn and turn, wings flickering, then suddenly still, as they stall, float, and snatch at the midges rising into the air among them.
