How fly fishing strengthens our connection with wildlife and fosters conservation efforts

Posted on by adele.hulin

Whether it’s to reset our mental health or simply to take time out from the hurly-burly of work and urban life, many of us head for oceans and rivers to enjoy their restorative capacities.

Encountering wild animals in these blue spaces contributes to the beneficial effects of being in nature and forms the basis of tourist economies the world over.

Yet, how does our presence affect the creatures that call blue spaces home, and how do encounters with wild species change our relationships with natural environments?

For nearly a decade, we have been researching human interactions with wild trout and salmon in the context of fly fishing. We spent months immersed in river environments both in the UK (the Lyd and Tamar in Devon, and the Usk and Wye in Wales) and North America (the rivers of the Gaspe region, Quebec and Lewisburg, Pennsylvania). We went fishing, observed and interviewed fly fishers, and learned as much as we could about fish behaviour.

In our recent paper, we explain how human interactions with fish can result in three kinds of interspecies encounters that strengthen people’s connections with wildlife and natural environments.

Separated encounters

Most often, wild animals remain indifferent to humans, driven as they are by natural motivations to feed and breed, within environmental habitats that humans do not fully understand.

For instance, Duane, a novice fly fisher we interviewed in Pennsylvania, didn’t know that trout eat aquatic insects: “I didn’t know squat … flies actually come out of the water?”

This lack of understanding of other species often ensures that wild animals remain undisturbed by human presence. Yet the elusiveness of creatures such as trout and salmon can also motivate people to find out more about them.

Slippery encounters

To improve their chances of catching fish, fly fishers learn about fish behaviour, river environments and the life cycles of the insects that fish feed on.

Equipped with this knowledge, fly fishers become better able to locate trout and salmon, and to select and cast a near weightless imitation “fly” designed to mimic a fish’s insect food.

Learning and honing these skills is a lifelong project during which fly fishers become savvy hunters with heightened abilities to sense what is going on in the water. Equally, fish learn too, becoming shy and ready to slip away from human contact.

Sticky encounters

On the rare occasions that fish are hooked, humans and fish enter what we call a “sticky encounter”. The mixed emotions of catching a wild salmon are captured in Annetta’s field notes:

I look down at this beautiful, majestic being. The fish is a fresh, healthy, silver, bright female … I look at her, she looks back at me … She wrangles free. She’s on a mission to spawn in her home river. I stand up but I’m weak in the knees. Full of pride, humility, and guilt.

Over time, these intense experiences of eye-to-eye contact can inspire fly fishers to consider the welfare of fish.

Fly fishers now release the majority of the fish they catch. Moreover, one fly fisher we interviewed explained that he has entirely removed the hooks from his flies, declaring: “I don’t want to catch that fish. I caught so many in my life. I know what the feeling is like.”

Stewarding blue spaces

It may seem ironic that fly fishers become passionate about conserving fish and river environments by practising what many people consider to be a cruel sport. Yet, fly fishers have first-hand experience of declining fish numbers.

Some of our interviewees spoke of trout and salmon as “canaries in the coal mine” – a warning sign of how river ecosystems are threatened by pollution, overdevelopment and climate change. In response, organisations such as the Wild Trout Trust and the Atlantic Salmon Trust highlight the necessity for conservation.

With wild populations of animals declining globally, the presence of humans in blue spaces deserves scrutiny. Nevertheless, interspecies encounters can change the relationship between people, fish and rivers from one of human gratification to one of reciprocity, stewardship and care.

Northeast (NE) India is more than just a region on the map; it is a treasure trove of beautiful
natural landscapes and ecological wealth that plays an essential role in our planet’s health. As
we celebrate World Environment Day 2024 with the theme of restoration, let us highlight the
ecological richness of Assam and the other Northeastern states of India. From the slopes of
Arunachal Pradesh to the lowlands of Assam, the NE region is a biodiversity hotspot, home to
unique species found nowhere else on Earth. The more we explore this ecological richness,
the more we discover the wonders and mysteries it holds, sparking our curiosity and interest.

The scenic landscapes of the NE region exemplify a dynamic and harmonious relationship
between humans and nature. Indigenous communities here have cultivated a profound
repository of traditional ecological knowledge passed down through generations. The Bodos,
Mishings, Karbis, Nyishis, Angamis, Khasis, and many others have developed a deep-rooted
understanding of their natural surroundings through intimate interactions with forests, rivers,
and mountains.

One of the most remarkable aspects of this traditional wisdom is the extensive knowledge of
local plants and their uses. These communities have identified and utilized numerous plant
species for food, medicine, shelter, and rituals, demonstrating a profound understanding of
the ecological roles of each species. For instance, the Bodos have long made use of medicinal
plants like Bhut Jolokia (ghost chili) for their therapeutic properties, contributing to the
preservation of traditional healing practices. This knowledge not only highlights the ecological
and cultural diversity of the region but also supports sustainable development and
conservation efforts.

Beyond plant knowledge, these communities have developed sophisticated ecosystem
management practices. Indigenous forest management practices in NE India have
significantly contributed to maintaining biodiversity hotspots and preserving wildlife habitats.
Traditional agroforestry systems, such as jhum cultivation practiced by the Karbi and Khasi
tribes, have shown resilience to climate variability while supporting local livelihoods. According
to a recent United Nations report, indigenous peoples’ territories encompass about 80% of the
world’s remaining biodiversity, underscoring the importance of their stewardship in
conservation efforts.

The wisdom of the hills and valleys also embodies resilience—a capacity to adapt and thrive
amidst changing circumstances. Indigenous communities have overcome challenges like
floods, droughts, and shifting climates by drawing on their deep ecological knowledge.

According to the Indian State Forest Report 2021, Assam’s forest cover is around 35% of its
geographical area, highlighting its critical role in biodiversity conservation and carbon
sequestration. However, this forest cover is declining, and the region faces environmental and
climate challenges, including deforestation, riverbank erosion, and climate change impacts.

Preserving and promoting traditional ecological knowledge is crucial in the face of the global
climate crisis. According to UNESCO, indigenous communities’ traditional knowledge
significantly contributes to the sustainable management of natural resources, benefiting both
local communities and global biodiversity. Recognizing, valuing, and supporting these
practices are essential for environmental conservation, cultural identity, and community
resilience.

Celebrating the wisdom of Assam and Northeast India’s hills and valleys on World
Environment Day reminds us of the transformative power of indigenous knowledge.
Integrating their insights into broader restoration efforts can contribute to building a sustainable
future for all. By embracing the wisdom passed down through generations and augmenting it
with contemporary research and statistics, we, the #GenerationRestoration, can pave the way
toward ecological harmony and resilience in the years to come.

Let us change gears to the tea communities of the NE region. Assam also plays a vital role in
India’s tea production, boasting over 312 210 hectares of tea cultivation. These tea plantations
not only fuel the state’s economy but also hold significant cultural and ecological value. Assam
is among the world’s largest tea-producing regions, with an annual production of 500-700
million kilograms (Mkgs) of tea leaves. The tea industry employs a vast workforce and
supports livelihoods throughout the region, contributing significantly to India’s overall tea
production. The tea plantations in Assam are not only unique but also serve as a prime
example of the harmonious blend of agriculture and biodiversity conservation. The lush green
tea bushes are seamlessly intertwined with shade trees, providing a habitat for various birds
and insects. Assam’s tea is globally renowned for its robust flavor and represents a heritage
deeply rooted in the land and its ecosystems. However, climate and environmental changes
threaten these lush industries, impacting the ecological and socio-economic balance in the
region.

The government has launched several key initiatives to promote development, ecological
conservation, and socio-economic growth across the state. Notable initiatives include the
Assam Budget for Sustainable Development, Assam Tea Tribes Welfare Board, Jal Jeevan
Mission (Har Ghar Jal), Assam Arunodoi Scheme, Assam Green Mission, Assam Skill
Development Mission, and Assam Startup. Effective implementation of these programs aims
to address climate change, promote environmental conservation, and improve the overall
quality of life for the people of Assam. However, the success of these programs depends on
thorough execution at the grassroots level.

What unfolds in the remote corners of Assam reverberates across continents. The lessons
gleaned from this region—on biodiversity conservation, traditional knowledge integration, and
community-led resilience—are universal. They inform global discussions on sustainable
development, emphasizing the need for inclusive approaches that prioritize both people and
the planet.

This World Environment Day, let us heed the call of Northeast India—a call to action for
environmental engagement and climate action involving youth, communities, government
agencies, and non-profit organizations. The region’s youth must understand the challenges
facing their environment and take action to safeguard their communities and natural
surroundings amidst infrastructural growth and development for their own and future
generations. Climate mitigation and adaptation strategies tailored to the region’s unique
context are critical, including afforestation, sustainable agriculture, and flood management
solutions. Youth can lead the way in developing context-specific climate adaptation and
environment restoration strategies that respect local cultures and ecosystems. By immersing
themselves in environmental education, research, and activism, young students can amplify
their voices and influence decision-makers at all levels.

Assam and its neighboring states in India stand out as a distinctive and valuable addition to
the mosaic of Earth’s landscapes. They serve as a beacon of hope and possibility in our
collective journey toward planetary stewardship. The region’s unique natural heritage,
combined with its rich cultural and ethnic diversity, makes it an important site for scientific
research and cultural exchange. As we strive to better understand and protect our planet,
regions like Northeast India offer invaluable insights and opportunities for collaboration.

Climate change: effect on forests could last millennia, ancient ruins suggest

Posted on by janet.crompton

Forests are home to 80% of land-based biodiversity, but these arks of life are under threat. The rising average global temperature is forcing tiny plants like sidebells wintergreen on the forest floor (known as the understory) to shift upslope in search of cooler climes. Forest plants can’t keep up with the speed at which the climate is changing – they lag behind.

The pace at which forests adapt to changing conditions is so slow that species living in forest understories today are probably responding to more ancient changes in their environment. For instance, the Mormal Forest floor in northern France is, in several places, covered by a carpet of quaking sedge. This long grass-like plant betrays the former settlements of German soldiers who used it to make straw mattresses during the first world war.

Changes in how people managed the land, sometimes dating back to the Middle Ages or even earlier, leave a lasting fingerprint on the biodiversity of forest understories. Knowing how long the presence of a given species can carry on the memory of past human activities can tell scientists how long climate change is likely to have an influence.

Ecologists are turning to technologies such as lidar to rewind the wheel of time. Lidar works on the same principles as radar and sonar, using millions of laser pulses to analyse echoes and generate detailed 3D reconstructions of the surrounding environment. This is what driverless cars use to sense and navigate the world. Since the late 1990s, lidar has enabled amazing discoveries, such as the imprints of Mayan civilisation preserved beneath the canopy of tropical forest.

In a new paper, I, along with experts in ecology, history, archaeology and remote sensing, used lidar to trace human activity in the Compiègne Forest in northern France back to Roman times – much later than historical maps could ever do.

Illuminating ghosts from the past

Compared to farm fields, which are ceaselessly disturbed, forest floors tend to be well-preserved environments. As a result, the ground below the forest canopy may still bear the imprints of ancient human occupation.

Archaeologists know this pretty well and they increasingly rely on lidar technology as a prospecting tool. It allows them to virtually remove all the trees from aerial images and hunt artefacts hidden below treetops and fossilised under forest floors.

Using airborne lidar data acquired in 2014 over the Compiègne Forest in northern France, a team of archaeologists and historians found well-preserved Roman settlements, farm fields and roads. Long considered a remnant of prehistoric forest, the Compiègne was, in fact, a busy agricultural landscape 1,800 years ago.

A closer look at these ghostly images of the Compiègne Forest reveals several depressions within a fossilised network of Roman farm fields. Archaeologists excavated numerous depressions like this across many forests in north-eastern France and found that people from the late iron age and Roman era carved them.

These depressions were made to extract marls (lime-rich mud) to enrich farm fields in carbonate minerals for growing crops and to create local depressions where rainwater collects naturally for livestock to drink. Marling is still a widespread practice in crop production in northern France.

The long-lasting effects of human activity

These signs of Roman occupation in modern forests provide clues to why some plant species are present where we wouldn’t expect them to be.

On a summer day in 2007 in a corner of the Tronçais Forest in central France, a team of botanists found a little patch of nitrogen-loving species – blue bugle, woodland figwort and stinging nettle – nestled among more acid-loving plants.

Nothing special at first sight. Until archaeologists found that Roman farm buildings had once stood in that spot, with cattle manure probably enriching the soil in phosphorous and nitrogen.

If a clutch of tiny plants can betray ancient farming practices dating back centuries or millennia, ongoing environmental changes, such as climate change, will have similarly long-lasting effects. Even if the Earth stopped heating, the biodiversity of its forests would continue changing in response to the warming signal, in a delayed manner, through the establishment of more and more warm-loving species for several centuries into the future.

Just as the Intergovernmental Panel on Climate Change has a mission to provide plausible scenarios on future climate change, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services aims to provide plausible scenarios on the fate of biodiversity. Yet none of the biodiversity models so far incorporate this lag effect. This means that model predictions are more prone to errors in forecasting the fate of biodiversity under future climate change.

Knowing about the past of modern forests can help decode their present state and model their future biodiversity. Now lidar technology is there to help ecologists travel back in time and explore the forest past. Improving the accuracy of predictions from biodiversity models by incorporating lagging dynamics is a big challenge, but it is a necessary endeavour for more effective conservation strategies.

Drone Ecologies: Exploring the opportunities and risks of aerial monitoring for biodiversity conservation

Posted on by janet.crompton

Drones, also known as unmanned [sic] aerial vehicles (UAVs), are becoming an increasingly common technology within conservation, with uses ranging from mapping vegetation cover, to detecting poachers, to delineating community land claims. Drones are favoured as they’re cheaper and simpler than rival remote sensing technologies such as satellites, yet despite their benefits, they pose a number of issues regarding personal privacy rights and can be difficult to navigate in environments like dense forests. Moreover, as social scientists have previously highlighted, monitoring technologies such as drones have the potential to be used for covert surveillance in conservation areas as part of what they call ‘green securitisation’ (Kelly and Ybarra, 2016; Massé, 2018). To date, however, there has been limited discussion between drone practitioners and scientists across disciplines regarding what a drone can do, and how it is done.

This was the inspiration behind Drone Ecologies, an online workshop hosted by the University of Bristol on the 5th and 6th of July 2021. With over 60 participants representing various disciplines across the social and natural sciences, as well as experts from the arts, industry, and NGOs, the workshop aimed to create an open space for important interdisciplinary dialogues concerning the use of drones for conservation purposes. Through a series of panels, presentations, and breakout activities, we discussed the technical, operational, and analytical dimensions of drones, as well as the ethical, political, and sociocultural impacts of introducing drones and other monitoring technologies into conservation spaces. This essay offers an overview of the conversations that took place during the workshop, and we invite others to take part in these ongoing discussions.

Our opening panel explored some of the operational benefits of drone technologies for environmental researchers. Drones can provide optical coverage over large areas with high spatial and temporal resolution, and have been successfully deployed to monitor various wildlife populations; assess changes in land cover; and map human-landscape interactions. However, with an increase in the technical capabilities of both drones and the sensors they carry, drones are becoming more than just airborne cameras. They can now be used to monitor other environmental components—e.g. noise, air pollution, and pollen levels—opening the door for new and diverse forms of data generation and analysis. Another emerging feature with huge potential for data collection is the integration of drones with other devices as part of the Internet of Things (IoT). Networks of coordinated drones that are able to share information and react in real-time could become instrumental in new anti-poaching efforts and for long-term, large-scale environmental monitoring.

Alongside a discussion of the advantages that drones provide for researchers and state agencies, much attention was given to the ways in which drones may be used to benefit local communities by, for example, monitoring forest fires within their concessions, or by demonstrating sustainable forest stewardship. Speakers such as Jaime Paneque-Gálvez and Nicolás Vargas-Ramírez from the National Autonomous University of Mexico showed how several community-based projects in South and Central America successfully utilised low-cost drones for participatory mapping processes. The researchers presented their experiences in teaching peasant and Indigenous communities in Mexico, Bolivia and Peru how to pilot and maintain drones, and how to incorporate drone-based imagery and orthomosaics into GIS products. These high-resolution, geo-referenced maps could then be used as evidence for territorial claims, or to expose environmental damage to forests and rivers. The use of drones granted the communities access to greater levels of spatial and temporal resolution with lower financial barriers, as well as greater degrees of inclusivity and autonomy over data collection when compared to satellite products.

Despite the logistical advantages of drones, there are still drawbacks regarding their use in environmental monitoring. Although they may reduce some environmental disturbances associated with monitoring—e.g. the cutting of tracks for transects—they also introduce new concerns, such as acoustic disturbance to wildlife under observation (and otherwise). However, some of the biggest concerns discussed during the second panel of the workshop were the negative impacts that drones may have on the communities living in and around the conservation areas being monitored. Trishant Simlai, a PhD candidate at the University of Cambridge, gave a plenary presentation showing how drones in India, along with other technologies used for conservation monitoring, form part of a deliberate system of surveillance and harassment of forest communities by the forestry department, exacerbating local inequalities along lines of class, caste, and gender, and producing ‘atmospheres’ of control. The second panel’s presentations also highlighted how, regardless of the operator’s intent, communities and individuals alter their behaviour when monitoring technologies are deployed by, for instance, avoiding areas that may have previously provided refuge and privacy.

During a group dialogue on green securitisation, Boise State University’s Libby Lunstrum posited several key observations on drones which formed the basis of ongoing conversations. Firstly, the militaristic origin of drone technologies raises concerns about the complicity of drone use with broader shifts towards militarised conservation and human rights violations. Secondly, unlike the cases presented by Paneque-Gálvez and Vargas-Ramírez, underlying power relations may mean that drone technologies are not always truly accessible for all community members. There are also epistemic concerns regarding the relationship between the disembodied and ‘objective’ knowledge purportedly produced by drones and the embodied and situated forms of knowledges produced by other, on-the-ground methods. Finally, there are a range of critical questions concerning the political economy of drone production: who is investing in these technologies? How do militarised actors participate in conservation, at times greenwashing harmful practices against local communities? How are drones complicit with these dynamics, and how do we reconcile that with their positive uses?

Given the above considerations, and the increasing use of drones for data collection, much of the final discussion at the workshop focused on the ethical implications of using drones within conservation. Drawing inspiration from Sandbrook et al.’s (2021) recent paper on the socially responsible use of conservation monitoring technology, we amended the guidelines set out in their paper to be specifically applicable to drones. Some key concerns included issues of proportionality—whether drones are always necessary tools for conservation practices—and the importance of recognising and foreseeing the potential for social implications in the first place. These concerns, we believe, are often obscured by the techno-optimism that surrounds drones, alongside a generally prevalent faith in technological solutions to conservation problems.

By the end of the workshop, it was clear that the use of drones for conservation purposes is a complex matter, and their use is subject to many conflicting ideas. Drones configure power relations in which social, political, and economic asymmetries and vulnerabilities can be exacerbated. However, drones can also be used for environmental justice purposes and can aid in the reduction of inequalities when their use is democratised and appropriate for local communities. The workshop also revealed some of the networks, assemblages, and ecosystems that drones inhabit, and that constitute power relations in which drones could play a role. It is important that these networks of relationships and interests that mobilise drones and other complementary technologies—e.g. satellite images—are made explicit, so that we can understand new configurations of power that are developing and identify those who benefit from the introduction of drones.

Additionally, the workshop also highlighted the relevance of multi- and interdisciplinary dialogues in understanding and developing the use of drones and other types of monitoring technologies for conservation purposes. We believe that it is important for these interdisciplinary networks to be established, and to continue exploring the complex impacts that drones have on environments, humans, and conservation practices. The interdisciplinarity approach simultaneously engages different disciplinary approaches and ethics, mitigating any blind spots within research and fully illuminating any potential damage or disturbances arising from drone use. This workshop marked an opening of these dialogues which we hope will continue within this emerging space, building towards the development of cross-disciplinary guidelines and policies for the ethical and responsible use of drones in conservation.

Who’s at the table? Priorities after a year of food justice dialogue

Posted on by janet.crompton

Defining ‘Food Justice’ is not easy. When it comes to ‘fairness’ and ‘equality’ in relation to our food system, should we be concerned with questions of individual citizens’ access to sustainable sources of subsistence, or issues of production, labour and the practices of agri-business? Do people have clear rights to food? And should such rights focus on quantity alone, or take account of the quality and nature of food? Furthermore, when defining ‘food justice’ should we be primarily concerned with human rights, or are we dealing with complex systems that oblige us to think about non-human persons and actors, including animals and the environment? Whatever our responses to these questions might be, it seems clear that thinking about climate change cannot ignore either food or justice.

An artistic collaboration is stimulating discussion about who is at the table in (un)just food systems.

Over the last year, we have established the Bristol Researchers Food Justice Network. Primarily, this has been through setting up a regular fortnightly seminar series, a workshop exploring the core purpose, values and potential for the Network, and an artistic collaboration to experiment with interactive ways of thinking about the food system and food justice. As it moves into its second year, we reflect on some of the key themes discussed so far. Recent models suggest that policy decisions that focus on climate alone will likely result in rapid growth in social inequalities, including and especially in the global food system. As we focus on questions of environmental sustainability and climate change in the light of the Cop-26 conference, some key food justice issues come to mind:

1. The way that we see food justice is systemic, equally as environmental as it is social

Every part of the food system is connected. Problems with diet are not disconnected to labour force, or price of food, or access to land, or environmentally sustainable farming. It is possible to have a food justice perspective towards understanding food systems. This involves seeing and considering people and other beings everywhere in the system and their being recognised as having an inherent value, with such value not being cheapened in the name of economic cost.

What clearly emerged from the network workshop, which involved researchers from vets to social scientists, historians and lawyers, was that we valued word and concept of ‘justice’ because it captures the common understanding that we are committed to change where we see injustice. While many network members understand food interactions as part of a ‘food system’, the concept of justice helps us maintain a critical and action-led approach where we see problems in those food systems.

2. Justice in food systems is bound up with structures of trade and foreign policy agendas

Since the mid-nineteenth century, Britain has largely relied on food imports, a model which has today become normalised. For many, changing this model is fundamental to building a more sustainable food system. But this cannot be a choice between either climate or society Recent government initiatives promise radical new directions in agriculture policy but keep this trade-centred model intact. Thus, the UK is determined to get farmers away from food subsidies, having committed to end direct payments by 2027. This would turn farmers into environmental stewards whilst offshoring the production of food elsewhere. Moreover, trade deals can increasingly be seen to trade away local and national food production in favour of other priorities, something that the network held a ‘policy hack’ discussion about following the approval of the UK-Australian Free Trade deal in June 2021.

Lauren explores how the table at the heart of the artistic collaboration is supported and wired together.

3. The Dutch model alone cannot save the world

Many models for the future of farming, food supply and food consumption, focus on technical solutions. Accounts of the ‘miracle’ of Dutch agriculture, for example, cite the emphasis on the investment in research and innovation that have underpinned the country’s apparent success in agricultural research and development. But what are the social implications of technological solutions – and what if we end up sacrificing quality for efficiency?

Will research led by agri-food corporations underpin a genuine revolution in global food production, or create intellectual property that marginalises small-scale and community-centred farming enterprises in ecologically-vulnerable territories in the Global South? Some agri-tech policies pioneered by countries such as the Netherlands – such as responsible antibiotic use – are to be lauded, but if these are pursued in the service of intensive agriculture, real problems remain.

4. Consumers are key to change – but we need to do more than blame and shame

As individual consumers, we all have a role to play in transforming the food system; but individualising systemic problems simply places the onus on the consumer in ways that often inhibit radical action. Moreover, as recent polling suggests, individuals are reluctant to embrace environmental actions – such as reducing meat consumption – that have the greatest impact on their own lives.

The choices we make certainly matter, but the notion of ‘choice’ is in many cases an illusory, erroneous and pernicious concept. In effect, consumers  are presented as ‘both the cause and the solution to potential health problems and thus are made to be accountable for their own health.’ This is especially true when we consider questions of poverty and its relation with obesity and other diet-based non-communicable disease. The idea that consumers, by choosing to consume ‘ethically’, ‘sustainably’ or ‘healthily’ can on their own resolve social and environmental deep-seated problems. Policies that place the responsibility for making healthy, ethical and sustainable food choices on individuals fail to address the contexts in which individuals and families live and work.

5. Agriculture and the people within it are being consistently undervalued, around the world

The current food system involves at least 1.1 billion people working in agriculture, who are often among the world’s poorest people. Peasant and self-sufficient farming practices, which often involve very low carbon emitting practices are routinely undermined by large infrastructure and deforestation practices, perpetuating a cycle of the mobility of people away from the agricultural sector that does not compensate them well (including through low international prices for primary agricultural products) towards more intensive practices in the same sector, or into other types of work.

Intensive agriculture relies on a waged labour force of 300-500 million, including many who depend on jobs in plantation work, which is degrading and, in some cases, involves forced labour and modern slavery, having emerged from systems of production developed under conditions of colonial slavery, such as in sugar plantations. Meanwhile, migrant workers make up a large proportion of seasonal and harvest workers in many rich countries because they are in a weak position in the labour force and are therefore, overall, are paid lower wages and offered poorer conditions than their national counterparts. Small producers across the world attempting to live in low-impact lifestyles are usually excluded from subsidies, but often even wealthy farmers, find their land crops and livestock are undervalued. To stay in the sector people working within it are frequently pushed into other activities to diversify and supplement their livelihoods through ecotourism or other specialised initiatives drawing income from the service sector. Why isn’t there inherent value to producing food?

6. The combined challenges of climate and biodiversity crisis for agriculture must be addressed as issues of food justice

A (contested) narrative is emerging that suggests it is possible to divide the world into areas which protect nature and areas which intensively produce food but have negative environmental consequences. We are thus presented with ‘difficult choices’ premised on the belief that farming is inherently incompatible with conservation and climate change mitigation.

This is an off-setting approach which uses a logic of ecological destruction in one place to be compensated for by nature promotion/restoration in another place. However, such ‘land sparing’ approaches simply maintain the status quo and distract our attention from the root causes of a problematic food system. We should be wary of policies that further outsource food production (and environmental damage) to prioritise environmental conservation/restoration in the UK and elsewhere.

Lead artist and ceramicist, Amy Rose, considers the dynamics present at the table. The collaboration is supported by the Brigstow Institute of the University of Bristol.

These represent some of the central issues we have begun to tackle in the Food Justice Network. As researchers, we also recognise that to fully address concerns around our contemporary food system, we need processes that expand our conversation, allow everyone to tell their stories and to fully engage all our senses. Working with artists and creative practitioners has started to help us broaden and clarify our definitions of food justice and will give us opportunities to engage and interact between and beyond the boundaries of research, public knowledge, and practice.

Creative practice and public engagement can become critical tools as we address the twin challenges of climate emergency and social inequality and their radical impact on our food systems – at local, national, and global scales. Above all, an  emphasis on food justice will be imperative if we wish to develop food policies that sustain both our environmental and human futures. Our current food system embodies historical systemic inequalities that reflect the diverse legacies of colonialism, industrialization, and globalization; these must be addressed rather than amplified in our responses to the climate emergency.

The ‘Ecological Emergency’ and what The Cabot Institute for the Environment are doing about it

Biodiversity loss and ecological decline pose enormous threats to humans and ecosystems alike, yet due to human activity they are occurring on a scale not seen since the last mass extinction. As part of our campaign running alongside the UN Biodiversity Conference (COP15), this blog will highlight The Cabot Institute for the Environment’s research contributions to the fight against the ‘Ecological Emergency’. 

The Ecological Emergency and the need for evidence 

Human activity is pushing the natural world beyond the limits of its own resilience, causing populations of species to plummet and ecosystems to collapse. As well as the widely appreciated beauty of the natural world and our responsibility to protect it, our reliance on ecosystems makes their survival essential to our own. Ecosystems provide us with food, oxygen, carbon capture, air and water purification, nutrient cycling as well as protection from erosion, floods and droughts. Under current trends, we could see ecosystems and the fundamental services they provide disintegrate within a lifetime.

The urgent need for action is starting to be recognised; a number of UK councils and organizations have declared ‘Ecological Emergency’ and the Climate and Ecological Emergency bill has recently been put forward to replace the ‘outdated’ 2008 Climate Change Act. Last year’s UN Summit on Biodiversity saw leaders from all regions of the world take the ‘Leader’s Pledge for Nature’, which commits to reversing alarming global trends and putting biodiversity and nature on the path to recovery by 2030. If ambitious but necessary targets are to be met, a strong evidence base surrounding ecological decline and its drivers will be fundamental in devising effective restoration and conservation strategies.

Caboteers have made significant contributions to global knowledge, directly influencing both local, national and international policy. Using statements from our experts, this blog will highlight some of our key research contributions to the field and discuss why they are so important in the fight against the ecological emergency. This is as part of the Cabot ‘Ecological Emergency’ Campaign, which is running alongside COP15, the UN Biodiversity Conference, which is taking place this week.

Restoration ecology 

Restoration ecology is the science which underpins ecological restoration – the much-needed repair of damaged and degraded ecosystems. Professor Jane Memmott, leader of the restoration ecology group, explained, “We work on the links betweenspecies, things like pollination, seed dispersal and predation, as it’s really important to reinstate these links between species, as well as the species themselves. We are particularly interested in species that have disproportionately beneficial effects – keystone species – as these can be used to help jump start restoration programmes.”

Identifying which habitats are the most effective to target in restoration strategies is another key element of the Memmott groups research. For example, ‘The Urban Pollinators Project’ led by Jane, was a inter-city, study surveying urban, natural and farmland pollinator habitats run over four years, with the aim of establishing urban restoration opportunities.

While urbanisation is known to be one of the drivers of biodiversity loss, the project found that cities in fact provide unique restoration opportunities. It found that the most beneficial actions for supporting pollinator networks were increasing the area of allotments, which were pollinator hot-spots, as well as strategic management of gardens and green space through incorporation of pollinator-supporting flower margins and meadows. Our reliance on insects to pollinate 75% of our crops and the alarming rate at which their populations are declining make this research particularly fundamental, and the findings have gone on to advise both local and national policy.

Experimental conservation 

Experimental conservation is research involving the testing and optimisation of conservation strategies. The experimental ecology and conservation group use mathematical models, small-scale experimental systems and long-term wild population data to do this. These techniques have the advantage of being generally non-invasive, leaving the ecosystems largely undisturbed, while giving huge amounts of crucial conservation information.

Dr Chris Clements, the experimental conservation group leader, explains, “My group develops and tests models which might help us to make more reliable conservation decisions. Our work covers a range of topics, including trying to predict what species and populations might be at most risk of collapse or extinction to understanding how multiple anthropogenically derived stressors might interact to increase extinction risk.” As time is limited and extinction is irreversible, ensuring conservation strategies are optimized and supported by a strong scientific evidence base is crucial to their success.

Forest ecosystems 

Forests are home to more than 80% of all land species of animals, plants and insects and are fundamental to our climate, as an integral part of the carbon cycle. Numerous global changes are causing their coverage to rapidly decline, and as well as this exacerbating climate change through reducing their ability to sequester carbon, it poses an extinction threat to the many species that call them home.

Dr Tommaso Jucker leads research investigating forests and the processes which shape their structure, composition and function. Tommaso explains “We hope to not only understand how forest ecosystems are responding to rapid global change, but also lead research that directly informs the conservation and restoration of the world’s forests.” Establishing a clear picture of what the world’s forests might look like in future is crucial to the conservation of the creatures which inhabit them, as well as for preparing for the impacts on people and climate.

Aquatic habitats and oceans 

The ocean constitutes over 90% of habitable space on the planet and the ecosystems within it contribute enormously to biodiversity, livelihoods, the carbon cycle and our food supply. This makes understanding the impact of human activity on these submerged worlds essential. As well as the pressure put on ecosystems by over-exploitation, pollution and habitat destruction, rising CO2 levels and are causing environmental changes in oceans, including warming and acidification.

Microbial ecologist, Professor Marian Yallop, and her group investigate aquatic microorganisms, such as algae and cyanobacteria, and their responses to environmental changes such as temperature, pH and pollutants. These often invisible microorganisms are pivotal to global oxygen production and carbon dioxide absorption, as well as occupying a critical position at the base of many food chains. This makes their fate crucial to that of the planet and all of the organisms on it.

Behavioral and evolutionary ecology 

Evolution and adaptations are at the core of a species ability to survive. In animals, a key element of this is behaviour. Rapid global changes are having complex implications on species and in many cases, the implications of human activity on animal behaviour are only just starting to be realised. Cabot has a number of behavioural experts working to better understand a variety of species behavioural responses to human activity, in order to understand how we can better manage our environment for their conservation.

Professor Gareth Jones, who predominantly works on bats, investigates their behaviour, evolution and responses to human activity, for example, how anthropogenic light can affect them and their insect pray, as well as how they can be deterred from dangerous infrastructure, such as wind turbines.

Professor Andrew Radford is a behavioural ecologist working on bioacoustics, so the production and reception of sound, on species from all across the animal kingdom. Anthropogenic, or ‘man-made’ noise has significantly altered the sound scape of habitats throughout land and sea, therefore, it is essential to understand how this might interfere with development and behaviour so that negative effects can be mitigated. Incorporation of behavioural insights into conservation and restoration strategies can contribute significantly to their success, therefore, research in the field is a key pillar of conservation.

Conservation Law 

If scientific research is to have a positive impact translated into the real world, it must be implemented in policy, meaning law is a hugely important element of conservation. Dr Margherita Pieraccini from the School of Law, who works predominantly on marine conservation law, explains “My research investigates the socio-legal aspects around ecological governance, with the aim of providing a critical understanding of existing conservation laws and envisaging ecologically just ways of governance.” Ecological decline will negatively affect everyone, however the consequences do not affect communities equally, therefore, evidence based conservation laws are essential to prevent inequality and poverty being exacerbated.

The Nocturnal Problem 

Establishing a full and accurate picture of where evidence is available, and where it is missing, is fundamental to shaping the future path of research and enabling us to protect all ecosystems. Dr Andrew Flack, an environmental and animal historian, is investigating what is known as ‘The Nocturnal Problem’, which is the significant underrepresentation of night-time ecologies in research. Dr Flack explains “My own historical research draws attention to the ways in which nocturnal ecologies and the threats to them have been understood, and that until very recently, scientists have neglected the impact of human activity on night-time ecologies.” Half of everything that has happened or will happen has happened in the night, therefore, nocturnal species make up significant proportions of our ecosystems. Neglecting nocturnal species in research can therefore have catastrophic consequences not only to those species, but to the diurnal (day-time) species that they are intertwined with through ecosystems.

The University of Bristol’s action on ecology and climate 

As well as being at the forefront of research, Cabot’s home institute, the University of Bristol, has taken a number of actions to support ecology. Wildlife supporting infrastructure, such as wild-flower meadows, bug hotels and ‘living buildings’ are dotted strategically around the campus. The Universities green space, Royal Fort Garden, is a hub of wildlife and supports a variety of species, as well as hosting an installation, ‘Hollow’, made of fragments of 10,000 species of tree from all over the world, inspiring interest in global biodiversity. The University was also the first UK university to declare a climate emergency in April 2019, and has set world-leading targets to reach net-zero by 2030. Mitigating climate change is fundamental to protecting ecosystems, however, as ecological decline could continue alongside decarbonization, or even be exacerbated by the means to get to net-zero, it is essential that it is not overlooked in sustainability strategies.

Ecological decline: an overlooked emergency?

Posted on by janet.crompton

The words ‘Ecological Emergency’ are appearing in an increasing number of environmental declarations, strategies and parliamentary bills. This blog will discuss the need to recognise ecological decline as an emergency in its own right, as well as being an element of the climate emergency. This will be part of an ‘Ecological Emergency’ Cabot Campaign which will run alongside the United Nations Convention on Biological Diversity (COP15), which is happening this week.

Last year, The Cabot Institute for the Environment’s home city Bristol became the first major city to declare an ecological emergency. This declaration came only two years after Bristol became the first European city to declare a climate emergency. Many UK councils and organizations have since declared joint “Climate and Ecological” emergencies, and the Climate and Ecological Emergency Bill has been put forward to replace the ‘outdated’ 2008 Climate Change Act. These declarations show that while climate and ecology are intrinsically linked, there is increasing recognition of ecological decline as an emergency in its own right as well as being a consequence of and contributor to the climate emergency. Climate mitigation is fundamental to safeguarding ecosystems, however, ecological decline could continue alongside decarbonisation and even be exacerbated by the means to get to net-zero, if the ecological emergency is overlooked in sustainability strategies and policy.

The UN Convention on Biodiversity (COP15) is taking place this week and a Cabot Campaign on the ‘Ecological Emergency’ will run alongside it. The campaign will include a series of blogs and posts across our website and social media. Using statements from Cabot researchers in relevant fields, this blog will discuss the ecological emergency and the need for targeted action.

What is the ecological emergency?

“Biodiversity is being lost on a scale not seen since the last mass extinction” Dr Chris Clements Caboteer and leader of the experimental conservation group explains. While Dr Andrew Flack, an environmental and animal historian, described the ecological emergency as “among the most profound crises of our time, diminishing not only planetary diversity but also the very experience of being human on our beautiful, rich planet“.

More quantitively, the statistics which drove Bristol’s pioneering ‘Ecological Emergency’ declaration include:

  • 60% of the worlds wild animals have been lost since 1970
  • One in seven UK wildlife species are at risk of extinction
  • More locally in Bristol and the surrounding areas, swift and starling populations have dropped by more than 96% since 1994
  • 41% of insects are threatened with extinction, posing a huge threat to our global food supply due to 75% of our crops being reliant on pollination by insects
  • Three-quarters of land and two-thirds of marine environment have been significantly altered by human actions

In their statements, many of our academics highlighted that, as well as the beauty of the natural world and our responsibility to preserve it, our reliance on ecosystems makes their survival essential to our own. Ecosystems provide us with food, oxygen, nutrient cycling, carbon absorption, air and water purification, and protection from erosion, floods and droughts. Many of these services are already under increased pressure due to climate change, which ecological decline is intertwined with. Destruction of ecosystems and exploitation of wildlife can also cause the emergence of infectious disease, as has been demonstrated by the occurrence of the current COVID-19 pandemic. Biodiversity loss and climate action failure both earned their own place in the top five threats to humanity in the next five years, according to the 2020 Global Risks Report from the World Economic Forum. Though these interdependent crises will drastically affect everyone, their consequences will not be felt equally among communities and are sadly already intensifying inequality and poverty.

Intertwined emergencies

 “The climate emergency is certainly exacerbating the ecological emergency” Professor Jane Memmott, a leading restoration ecologist, explained. Under current trends, climate change is projected to drive many ecosystems to collapse. Simultaneously, large-scale destruction of ecological carbon sinks, such as forests, wetlands and mangroves, is contributing to climate change. There are several feedback loops at play: destruction of carbon sinks is increasing atmospheric CO2, which drives climate change and in turn further ecological degradation, which then further debilitates natures ability to store carbon. This forms a vicious cycle, with profound consequences for the planet.

The interdependent emergencies share similar causes, consequences and solutions, however, Dr Tommaso Jucker, whose research is on forests and their responses to rapid global change, explains “it is not only climate change that threatens biodiversity, and the effects of biodiversity loss on people will not just be a subset of those brought on by climate change”. As well as climate change, threats to ecosystems include species over-exploitation, habitat destruction, pesticides and pollution of land, air and water. These could all continue simultaneously to our efforts to decarbonise, and even be exacerbated by the means to get to net-zero, if the ecological emergency is overlooked in sustainability strategies.

A coordinated approach to climate and ecology

The climate emergency is becoming mainstream conversation and it is now widely accepted that huge changes in policy, infrastructure and behaviour are needed. However, while the climate emergency is gaining recognition, the ecological emergency is comparatively overlooked. If we are to avoid ecological collapse, a co-ordinated approach to the crises is essential; focusing purely on technological advancement and decarbonisation runs the risk of allowing and even exacerbating further ecosystem destruction.

Natural climate solutions, such as strategic management of forests, grasslands and wetlands, can offer around a third of the climate mitigation required by 2030 to keep warming below 2 °C. These environments are not only carbon sinks, but biodiversity havens, making them effective solutions for ecological decline as well as climate change. Protecting ecosystems is also often significantly more cost-effective than human-made climate interventions. However, due to our often unnatural lifestyles and a fast-growing population, nature alone will not be enough to mitigate human impact on the environment.

The need for targeted action 

As well as the intrinsic links and coordinated solutions to the climate and ecological emergencies, there is a lot that can be done to specifically alleviate the ecological emergency. This is exemplified by Bristol’s ‘One City Ecological Emergency Strategy‘ which predominantly focuses on land management, pesticide use, water quality and consumption of products that undermine global ecosystems. This is in addition to climate mitigation, already covered in the Climate Emergency Action Plan.

Last year’s UN Summit for Biological Diversity saw leaders from all regions of the world take the ‘Leader’s Pledge for Nature’, which commits to reversing alarming global biodiversity loss trends by 2030. To achieve this ambitious but necessary goal, both climate action and targeted conservation and restoration strategies will be needed on both a local and global level. For these crises to be mitigated, some uncomfortable truths surrounding lifestyles many have become accustomed to will have to be faced.

The word ‘emergency’ from a scientific perspective 

Despite widespread agreement on the obvious threats posed by biodiversity loss and the need for action, the word ‘emergency’ can be controversial, especially amongst the scientific community. Professor Richard Wallexplained “As a research scientist, my view is that the sound-bite ‘ecological emergency’ is not sufficiently nuanced to be useful in scientific discourse and is best left to journalists and campaigners; it has no scale or quantification and what constitutes an ‘emergency’ is highly subjective.”

Public awareness surrounding our changing climate and declining ecosystems are important, however, if action doesn’t follow declarations, then they run the risk of being no more than empty PR stunt and can increase public immunity to the word as well as the impacts of the crisis itself. COP15, which is happening this week, will be pivotal in deciding the future of our own species, as well as all the other species that share our planet.

Global Environmental Change mini-symposium

Posted on by janet.crompton

At the end of June, the Cabot Institute hosted the Global Environmental Change mini-symposium – a one hour whistle-stop tour showcasing the breadth of research within this theme of the Cabot Institute. Speakers represented different schools from the University that actively work on the spectrum of Global Environmental Change challenges, such as environmental law and policy, biodiversity conservation, biogeochemical cycles, environmental justice and environmental history.

 
Each speaker had time for a very short talk, with some choosing to focus on specific aspects of their work in depth and others instead covering the breadth of research carried out by colleagues in their school. The audience too came from a wide background, with everyone from undergraduate and masters students up to professors represented. Although with five speakers (plus some words from the theme leaders, Jo House and Matt Rigby) there was not much time for questions during the hour of talks, there was plenty of time for discussion over food and drinks afterwards.

Although it was billed as a miniature event, it set out to address grand, ambitious, global challenges. It was a short, punchy reminder of the huge range of research skills found within the Cabot Institute. We might not have solved the Earth’s challenges in an hour or two, but now that the dust has settled we certainly have a good idea of who to ask and how to start taking them on. I look forward to the mini-symposiums for the Cabot Institute’s other five research themes!

The speakers were:
Kath Baldock – Life Sciences
Alice Venn – Social Sciences and Law
Alix Dietzel – SPAIS
Kate Hendry – Earth Sciences
Daniel Haines – History

The event was hosted by:
Jo House – Geographical Sciences
Matt Rigby – Chemistry

Sea and Sky

Posted on by janet.crompton

I’ve always loved the sea. Pursuing a major in oceanography led me to chose a degree in Physics and it was I realised that studying the atmosphere was just as, amazing, if not more so! I therefore decided to pursue a PhD in atmospheric sciences. But once the sea captures you, it never really lets you go. That is how I found myself between the sea and sky.


Several years ago, a group of like-minded friends and I decided to start an NGO, based in Croatia, called Deep Blue Explorers that would focus on marine and atmospheric sciences and research. That task proved to be extremely challenging as getting the funding we needed to start our adventures seemed to be a little harder than we had anticipated. However, we were fortunate enough and, after a very rough first season, we started to collaborate with Operation Wallacea who design and implement biodiversity and conservation management research expeditions with university and high school students from all over the world.


At the same time, we started collaborating with another Croatian NGO called 20.000 Leagues who have over 10 years of experience in marine research. Together, we are running the Adriatic Ecology Course that aims to bring together scientists and experts from all over the world to give international students a hands-on experience of field work and high-quality research. The course takes place in the National Park of Mljet and the research includes fish, sea urchin and sea grass surveys. Additionally, the students conduct boat monitoring in Lokva bay, three times a day, in order to record the pressure of
boats anchoring in the Bay.
 

The expedition is supported by scientific lectures regarding conservation in the Adriatic; the ecosystem and biodiversity of the island of Mljet; sustainability; research methods and global challenges such as marine pollution. The students also have the opportunity to be involved in workshops to discuss conservation and global challenges issues and to take part in personal and professional development training activities that focus on sustainability and protection of marine life.
 

It is an amazing experience for everyone and the students leave the Island with a new understanding and new appreciation of the ecology Island of Mljet, the contribution of the National Park regarding conservation and the need and importance of supporting the National Park’s efforts.
 

As for me, being able to work both with the sea and the sky, I can just say, I have never been happier!

Do we care too much about nature?

Posted on by janet.crompton

Over 80% of British adults believe that the natural environment should be protected at all costs. Yet, a recent report suggests that “government progress on commitments to the natural environment has been largely static” (1). Indeed, the budget for DEFRA, the Department for Environment, Food and Rural Affairs, has been slashed by 10% (£37m) and a reduction in green levies is likely as the government attempts to reduce domestic energy bills.

Has the government lost interest in the environment? Or do we care too much about nature?
To discuss this further, the Cabot Institute hosted a public recording of BBC Radio 4′s Shared Planet, a show which explores the complex relationship between the human populations and wildlife. John Burton, CEO of the World Land Trust (WLT), was the first panellist and is a well known journalist and conservationist who has raised £19m for nature conservation in Africa, Asia and Central and Southern America. He believes that we should think about policy on “the life scale of an oak tree” and that further measures are required to protect the environment, both at home and abroad. The second panellist, Hannah Stoddart, is the head of the economic justice policy team at Oxfam GB and believes that fairer redistribution of wealth is more important than wildlife conservation.
Do we care about nature?
A new report, by the Environmental Funders Network, suggests that one in ten UK adults are now a member or supporter of Britain’s environmental and conservation groups (2). This equates to nearly 4.5 million people, with 81 organisations protecting species and 78 working on climate change. Although 44% of funding is allocated to biodiversity and nature protection, only 7.3% of total funds have been allocated to the climate and the atmosphere. This suggests we are more interested in ‘traditional’ environmental issues than climate change. A recent research project by the RSPB indicates that four out of five UK children are no longer connected with nature (3). Dr Mike Clarke, the chief executive of the RSPB, explains that “…nature is in trouble, and children’s connection to nature is closely linked to this”. At a time where UK species are in decline, are we doing enough to engage young people in the natural world?
An alternative to conservation
Both John Burton and Hannah Stoddart agree that nature is important and that conservation can help protect endangered landscapes. However, many conservation sites are maintained in ”favourable condition”. In other words, they are kept in the condition they were found when designated as conversation sites. A alternative concept, known as rewilding, attempts to reverse the destruction of nature by standing back and allowing nature to control its own destiny.
Currently, farmers have to prevent the development of foreign or exotic vegetation on their land. This results in the development of bare land, lacking in biodiversity. Removal of the ‘agricultural condition’ rule and the introduction of rewilding may allow this land to flourish once again. George Monbiot, author of Feral, is particularly interested in the reintroduction of megafauna, large animals that existed at the end of the last glacial period (>11ka) (4). It seems hard to believe, but over ten thousand years ago, elephants, rhinoceri and camels roamed Europe while other animals, such as bison, wolves and wildcats, were particularly widespread throughout the UK.
Indeed, the re-introduction of missing species can have a profound effect on wildlife. In 1995, grey wolves were reintroducedto Yellowstone National Park for the first time in 50 years (5). The elk population, who were now at risk of predation by wolves, began to redistribute. This allowed willow and aspen trees to flourish and increased the habitat for certain bird species, small mammals, beavers, and moose. This effect, known as a trophic cascade, suggests that careful reintroduction of megafauna into the wild can allow ecosystems to flourish. However, rewilding can backfire. In 2008, endangered Mallorcan toads were reintroduced into the natural population but were infected with Batrachochytrium dendrobatidis, a well-known fungus that can threaten amphibians (6). As a result, the Mallorcan toads are now in danger of being wiped out once again. Despite this, I believe that rewilding in the UK is feasible and could allow the public, especially children, to reconnect with nature in new and exciting ways.
