Cabinet of Freshwater Curiosities

November 24, 2010

This photo of Carribean flamingos flocking in the shape of a flamingo (!) in the Yucatan, Mexico in yesterday’s Guardian seems an apt way to introduce the relaunched BioFresh Cabinet of Freshwater Curiosities.

The Cabinet of Freshwater Curiosities is a modern adaptation of the Cabinet of Curiosities concept, intended to foster interest into the often neglected world of freshwater ecosystems. The Cabinet collects and collates a selection of the world’s most fascinating, bizarre and unique freshwater plants, animals and phenomena (much like the flamingos above!). It provides an interactive platform for users to engage with some little-known oddities and become further immersed in the curious world of freshwater ecosystems.

The site is highly interactive and linked to various social media platforms to encourage users to submit ratings, comments and suggestions for future “curiosities”.

Feel free to explore the Cabinet here, and let us know your thoughts.

Citizen science and new technology

November 18, 2010

Project Noah

Increasingly affordable digital camera and smart phone technology is being used to attempt to engage the public with the natural world and biodiversity conservation.  Citizen science – where the public are involved as active researchers or collectors of biodiversity data – is being increasingly fostered by initiatives such as Project Noah.  Project Noah allows the public to use a smart phone app to document (through photographs, measurements and map readings) the plants and animals they encounter.  These “spottings” are mapped along with other user data to give a field guide to the wildlife found in a particular area, and can be ratified by independent experts.  Project Noah also sets the user “missions” to spot a particular organism, and the data collected can be used to track processes such as the spread of migrating or invasive species.

This initiative is part of a larger movement to use new technologies to engage the public with the natural world.  iSpot provides an online community for users to help identify photographed organisms; and projects like the OPAL Biodiversity Survey, the RSPB Big Garden Bird Watch or the Christmas Bird Count in the USA are increasingly using the internet to allow the public to submit their observations and sightings.

This reflects a shift to the increasing democratisation and openness of scientific knowledge.  Historically, scientists and the public have largely existed as separate poles, with the communication of science aiming to fill a perceived “deficit” in public understanding.  This “deficit model” assumes that once scientific literacy is improved then the public will understand how and why scientific decisions are made, and so avoid any controversy or debate.

However, this model is being viewed as increasingly flawed.  Citizen science projects such as Project Noah fall under an alternative “public engagement” model that aims to empower the public in environmental decision-making by connecting environmental problems to their daily lives, values and beliefs.  The science-public relationship becomes a dialogue, fostered through citizen science projects, community forums and novel means of science communication (see for example the BioFresh Cabinet of Freshwater Curiosities) to understand and influence how science is translated into environmental decision-making.

There are concerns that the data collected by citizen science projects is unreliable and inaccurate.  Certainly, a browse through the Project Noah site reveals a number of “spottings” of pets, garden plants and fishermen’s trophy catches.  However, you could argue that the quality of data is necessarily the key point to citizen science; it is instead the fact that it encourages people who may not otherwise to step outside and take notice of the natural world around them – even in a highly urban area.

As such – and seemingly paradoxically – I wonder if there is the potential for new digital technology to make it easier for the public to reconnect with the natural world?  How would such a connection work?  Do new technologies necessarily keep us at arms length from the world around us, or do they give new ways to reinvigorate our engagement and enjoyment of it?

As ever, let us know your thoughts, comments and suggestions.

Can big brands help save biodiversity?

November 9, 2010

As a rule, many people associate the growth of large commercial corporations with environmental degradation.  In this presentation to the TED conference earlier in the year, WWF vice-president Jason Clay outlines a radical vision of uniting commercial, multi-national brands to agree on imposing environmental sustainability standards as a prerequisite to the trade of 15 popular and environmentally important commodities such as palm oil, timber and fish.  Clay’s argument is that large corporations should be encouraged to strategically co-operate in setting environmental sustainability as a pre-market and pre-competition stipulation in their products.

Ambitiously, Clay asks that the pressing global need to reduce environmental degradation should persuade corporations as fundamentally opposed and competitive as Pepsi and Coca-Cola to co-operate for a common good.  He argues that as a relatively small number of corporations are responsible for the majority of the trade of the most important commodities, it is logical to target them, rather than “downstream” retailers or consumers.  By uniting a roundtable of 100 key global companies to agree on common pre-market environmental standards for their products, Clay hopes that global markets will shift to foster the protection of a planet that they have outgrown.

Applied appropriately, the vast resources available to large companies could potentially be invested into research which understands how commodities may be sustainably used whilst retaining economic productivity.  For example, Mars is investing in sequencing the genome of the cocoa plant to isolate traits of productivity and drought tolerance. Where on any given plantation, 20% of the trees produce 80% of the crop, Mars could be now looking at plants that could produce 320% as much cocoa on 40% of the land.  This land sharing approach could then ideally be used to foster biodiversity conservation and rural livelihood enhancement.

Biodiversity conservation is  increasingly engaging with economic markets.  Traditional methods of “fortress conservation“, where species are protected by designating parks and reserves where nature “is” and humanity “is not” have been shown to often be conceptually and practically flawed in preserving a wide range of biodiversity and human livelihoods.  Increasingly, attempting to foster sustainable resource consumption through the markets –  whether directly through big corporations as Clay outlines, or through ecosystem services valuations (see for example, The Economics of Ecosystems and Biodiversity) – is seen by many practitioners as a radical, but necessary step to preserving global biodiversity.

What do you think?  How feasible is Clay’s vision of large corporations agreeing pre-competition environmental standards?  Should the conservation movement even engage with economic markets?  As ever, we welcome your comments and ideas.

IUCN Biodiversity Video – Love. Not Loss.

November 5, 2010

Last week, the International Union for the Conservation of Nature released this video challenging negative “doom and gloom” environmental messages:

The video’s positive, hopeful message of “Love. Not Loss.” chimes with the themes discussed a few weeks ago in our post following the fall-out from the 10:10 climate video.

We at BioFresh are thinking a lot about how environmental messages are best communicated – any thoughts on the video, or the debate in general, are welcomed.

What is a natural freshwater ecosystem: invasions, aliens and novel ecosystems

November 2, 2010

Derwent Water in the English Lake District: the last remaining native habit of the vendace (Coregonus vandesius) which is predated by introduced populations of the non-native ruffe (image: wikicommons)

At first glance, defining a ‘natural’ ecosystem seems relatively straightforward.   However, on closer inspection, an understanding of the ecological, climatic and cultural histories of a landscape muddies the waters of identifying a set ‘natural’ ecosystem state.  Global ecosystems are in constant flux, influenced by both natural processes and human influence over thousands of years, which makes defining a natural state for their conservation or restoration difficult.

Writing in Freshwater Biology in January, David Strayer discusses the effects of biological invasions of ‘alien’ species into global freshwaters, creating new and ‘novel’ ecosystems.  Such invasions are becoming increasingly common, with species spread in ship ballast water (e.g. the round goby), through the aquatic trade (e.g. Canadian pondweed), deliberate introductions, and angler’s bait buckets (e.g. the introduction of ruffe in Scottish lochs).

Zebra mussels (image: wikicommons)

There are numerous economic, environmental and cultural services and benefits resulting from the conservation of biodiverse and distinctive freshwater ecosystems – see this short interview with BioFresh partner Dr. William Darwell for more details.   Allowing biological invasions to occur unchecked may lead to ecosystems becoming dominated by highly adaptable ‘generalists’ like the zebra mussel or the round goby, potentially at the expense of ecosystem diversity and function (dubbed the “Homogecene”).

Round goby (image: wikicommons)

Given that current ecological thought stresses how ecosystems are in a constant state of flux, it could be argued that we accept biological invasions as natural processes thathave occurred countless times in the past.  As Stephen Jay Gould describes, on an evolutionary timescale species are only native to a particular area through a series of chance events, and aren’t necessarily better adapted to their habitat than ‘non-native’ species.  However, the issue isn’t that biological invasions are still occurring – it is that their rate and magnitude is being significantly increased by human influence.

Returning then to the idea of what constitutes a ‘natural’ ecosystem, Strayer’s paper raises a number of important points.

The composition of global ecosystems are being increasingly reshuffled and altered.    Any attempt to conserve or restore a ‘natural’ ecosystem must be aware of these processes.     Strayer’s research suggests that freshwater ecosystems will continue to be flooded with new invasive species in the future, creating new ecosystem assemblages with no historical equivalent to guide their management.  His conclusion states “the best solution to the management problems caused by alien species will be to work aggressively to cut the arrival rates of new invaders”.

For Richard Hobbs and colleagues, biological invasions make us re-assess a stark distinction between ‘natural’ and ‘non-natural’ ecosystems – moving away from an over reliance on excluding alien species at all costs, instead focussing on appropriately managing emerging ecosystems .  This may seem like a defeatist approach, but as Hobbs and colleagues suggest, we are faced with an unprecedented rate of ecosystem change, making exclusion of new invasive species extremely difficult.

Responding to the comments on a draft of their paper, they conclude dryly that:

one reviewer commented that the examples[of novel ecosystems] are ecological disasters, where biodiversity has been decimated and ecosystem functions are in tatters, and that ‘it is hard to make lemonade out of these lemons’.

Our point is, however, that we are heading towards a situation where there are more lemons than lemonade, and we need to recognize this and determine what to do with the lemons”


How far do biological invasions make us re-assess what we term a ‘natural’ ecosystem?

Do you agree with Hobbs and colleagues that we should focus our conservation efforts on appropriate management of new and novel ecosystems rather than relying solely on excluding new invaders?

As ever, we welcome your thoughts.

Hungarian red sludge spill – three weeks later

October 26, 2010

Toxic spill near Ajka, Hungary: a NASA satellite image shows the spill clearly visible from space (Image: http://earthobservatory.nasa.gov/)

This week’s post is written by Dr. Szabolcs Lengyel, Assistant Professor of Ecology at University of Debrecen, Hungary and a member of the BioFresh project.  Dr. Lengyel offers a Hungarian perspective on the toxic waste spill from an aluminium factory near Ajka, Hungary on 4th October which killed seven people and severely affected surrounding ecosystems.

Three weeks have passed since the worst environmental catastrophe to affect Hungary and the first sizeable spill of red caustic sludge anywhere in the world. By now, the waves of the spill have faded and toxic concentrations have diluted. Life is starting to make a comeback in the villages and landscapes affected by the spill. However, three weeks after the spill, questions remain over its causes, responsibilities and impacts

Nobody is sure exactly what caused the spill.  Careless dam construction, sliding layers of soil, irresponsible use of the reservoir by the company, insufficient environmental inspections or a combination of these have all been cited. Nobody talks about why the solution to get rid of almost one million m3 of red sludge is to simply let it flow down into the catchment of the largest river in Europe.

We must question how appropriate the environmental inspection and disaster prevention activities of the relevant authorities had been before the catastrophe?

It is now uncertain what happens when heavy metals from the spill – bound in complexes at highly alkali pH – go into solution at lower pH.   And what will happen when the sludge dries and its heavy metal and arsenic-rich dust is dispersed by the wind?

Few media reports mention freshwater life. The highly alkali (pH = 13.8) red sludge covered more than 1000 hectares of land and killed all life in the Torna-patak and Marcal rivers, seriously damaging all living populations downstream on Rába. pH on river Danube decreased below 9 only after day 4, and fish dwelling on the river-bottom have suffered greatly.

An absurd result is that sturgeon, a Natura 2000 species dwelling on the bottom of Danube, have been found killed by the spill in numbers exceeding even the lowest estimates of their population size. Dead sturgeon were found on river sections where their presence had been previously unknown.

I believe the only positive development of the spill is to draw attention to the importance of such environmental ‘time-bombs’ hidden in the backyard of former communist countries.   It is crucial that better environmental inspection standards are implemented by authorities to prevent similar disasters in the future.

What is the role for zoos and aquaria in conservation?

October 21, 2010

Modern zoos are an increasingly influential voice in global biodiversity conservation.  Earlier this year, the European Association of Zoos and Aquaria (EAZA) released a video outlining their vision for the role of their members in conservation programmes:

There are many arguments for the value of such ex situ conservation.  For many people, zoos provide an important source of engagement and education about the natural world.  The revenues raised by zoos may be also be reinvested in in situ conservation projects – see for example the Zoological Society of London’s conservation outreach programmes.

The accumulated knowledge and expertise held by many zoos can also be put to use in breeding and reintroduction programmes for species otherwise endangered or extinct in the wild (for example, see the La Palma pupfish –  this month’s entry into the Cabinet of Freshwater Curiosities.

However, critics argue that zoos only foster a partial and unrealistic public engagement with nature – prioritising only the most charismatic and exotic species.  Similarly, there is a concern that the over reliance on zoos as the last habitat for many endangered species may channel attention and funds away from the conservation of their natural habitats.

There are an increasing number of ex situ programs involving zoos and aquaria targeted at the conservation of freshwater species.  For example, the IUCN Turtle Survival Alliance created a network of zoos, aquaria and private breeders to maintain viable populations of freshwater turtles, with a view to reintroductions in the wild.  Similarly, Amphibian Ark is a collaborative project which uses captive breeding to ‘rescue’ dwindling populations of endangered amphibians.

What role should zoos and aquaria play in the global conservation movement?  How far do they lead to a positive and productive public engagement with nature?

As ever, we’re keen to hear your views.

Getting it together for freshwater ecosystems

October 15, 2010

blog action day logo
Today, thousands of bloggers across hundreds of counties will take part in Blog Action Day, an annual event to raise awareness about a single topic – this year focussed on freshwater.  An impressive list of participants – including Google, Greenpeace and the White House blog – will all post on a range of human rights, environmental, animal welfare and sustainability issues surrounding access to clean water.

We believe that BioFresh can lend an important voice to this discussion.  By creating a shared network of global freshwater biodiversity data, the project will better our understanding of the status and trends of freshwater ecosystems, and so allow effective conservation strategies to be planned.  This week’s post on a recent Nature article emphasised the pressing need for accurate biodiversity datasets in order to map the threats faced by freshwater ecosystems.

The value of this data lies solely in its use.  That’s why we are spearheading new and creative ways of engaging new users with BioFresh in order to encourage use of our open access data portals, and to raise awareness of the urgency of biodiversity loss from freshwater systems.  Whilst our focus is on biodiversity, the conservation of healthy freshwater ecosystems provides numerous beneficial services to humans – such as water security, clean drinking water and flood control.  Today’s Blog Action Day is about raising awareness of these benefits, and highlighting the numerous threats to freshwater ecosystems.  We at BioFresh are glad to be involved.

Nature study identifies need for new data to map the effect of water security investments on freshwater biodiversity

October 13, 2010

Writing last month in Nature, Charles Vörösmarty and colleagues provide the first global synthesis of threats to human water security and biodiversity services provided by freshwater ecosystems.  The study shows that human water security and freshwater biodiversity share many threats. However, vastly more data and investment is available for improving human water security than for freshwater biodiversity conservation. Importantly, the fact that many water security interventions impact negatively on freshwater biodiversity highlights the challenges in balancing ecosystem management to address both human livelihood improvement and biodiversity conservation.

The study collated data on 23 stressors on freshwater systems under four themes – catchment disturbance, pollution, water resource development and biotic factors – to suggest that over 80% (4.8 billion people) of the world’s population is exposed to high levels of water security threat.

The highest threats (yellows, oranges and reds) to both water security and biodiversity were found where water resource development (e.g. dams and flood defences) and pollution levels were highest – in Europe, the USA, China and India.  As there are many (and often local) factors that influence threat calculation, Vörösmarty and colleagues argue for integrated strategies to address ecosystem rehabilitation.

 

Global geography of threat to human water security when adjusted to include investment into water technologies. Blues reflect lower threat; reds reflect higher threat From http://www.riverthreat.net/ (13/10/10)

 

Wealthy nations are in a better position to improve their water security through technological investments (e.g. reservoirs, sanitation plants), thus widening the gap with poorer countries.  Vörösmarty and colleagues suggest that such investments into improving human water security may have direct negative impacts on biodiversity (e.g. dams impeding migratory fishes). Unfortunately, due to the lack of available data the authors were unable to map the effects of this investment on biodiversity.

As the environmental impacts of climate change and population growth increase in the future, the challenge of implementing such integrated management strategies is likely to become increasingly important.  However, without adequate data on the distribution, status and trends of global freshwater biodiversity, how can successful integrated management strategies be designed?  As Vörösmarty and colleagues suggest, policymakers and water managers require high-resolution biodiversity data at scales relevant to their decision-making.

The BioFresh project aims to build a freshwater biodiversity information platform to bring together, and make publicly available, the vast amount of information on freshwater biodiversity currently scattered among a wide range of databases.  However, this study demonstrates that there is a need for futher work in quantifying and communicating the threats faced by global freshwater biodiversity.

The fundamental question remains: how to manage global ecosystems in a manner that balances the needs of both humans and nature?  As ever, we’d welcome your comments.

‘No pressure’: how should environmental messages be communicated?

October 5, 2010

Last Friday’s launch and rapid withdrawal of a high profile climate change campaign video illustrates the pitfalls and tensions in environmental communication.  The 3 minute video, directed by Richard Curtis (director of Love Actually, Four Weddings and Funeral) aimed to bring climate change “back into the headlines whilst making people laugh”.  Unfortunately, the joke – blowing up schoolchildren, the footballer David Ginola and actress Gillian Anderson for not agreeing to act to reduce their emissions after being told ‘no pressure’ – spectacularly backfired.

Classroom scene from the controversial 10:10 video. Image: YouTube

The imagery chimes with contemporary themes of terrorism, war and militant fundamentalism, and if blog traffic is anything to go on the 10:10 campaign is being accused of being either very naïve (see here, here or here to begin with) or eco-fascist.

The video (and subsequent reaction) illustrates contemporary debates on ways to communicate environmental issues and the underlying science.  Broadly, these revolve around notions of fear/crisis-based vs. vision-based messaging.

Fear or crisis-based messages commonly aim to shock viewers into action through presenting graphic or disaster-strewn representations of the need for rapid environmental action.  For example, Conservation International have used Harrison Ford’s chest hair to highlight deforestation; the UK government Act on CO2 campaign pictured a doomsday twist on a child’s bedtime story;  and anti-aviation pressure group Plane Stupid depicted polar bears falling out of the sky to highlight CO2 emissions from aircraft.  The 10: 10 video falls into this category, ironically posing the phrase ‘no pressure’ whilst explicitly (admittedly in a slapstick fashion) blowing up anyone who doesn’t comply by making pledges to lower their carbon emissions.

A vision-based approach tends to be more subtle, attempting to align a vision for environmental action with the audience’s values, beliefs and aspirations.  For example, WWF used the pride and adulation fans devote to Benfica football club to highlight the plight of an endangered eagle.  This process (often termed ‘framing’) treads a fine line between presenting an easily relatable (and often hopeful) message without watering-down the underlying science or lapsing into political ‘spin’.

We have debated the merits of the two approaches in media workshops at Oxford for the last 4-5 years, and one insight is that messages of impending crisis attract the attention of politicians and policy makers but turn off the general public.  Instead, most people are thought to respond most positively to environmental messages of hope (two academic papers from Oxford on this subject can be found here and here).

BioFresh decided on vision-based, hopeful messaging – see for example the Cabinet of Freshwater Curiosities – but is this the best approach to take?  Whilst we wouldn’t go so far as blowing people up, should we be more vocal and sensationalist on the risk to human well-being that recent evidence on decline in African freshwater biodiversity or the extinction threat faced by many species of sturgeon might indicate?  Are crisis-based messages more effective at communicating environmental issues? Or are you tired of sensationalist, ‘doom and gloom’ environmentalism and so more receptive to a constructive, hopeful, vision-based alternative?
