Stockholm+50: No way to have a conversation about climate change

Posted on June 13, 2022April 16, 2023 by janet.crompton

I’m just back from Stockholm+50, the summit convened to mark 50 years since the first UN conference on ‘the human environment’ that led to the founding of the UN Environment Programme. Could the participants then have imagined that half a century later we would be living through mass extinctions and still be trying to work out how to stop (some) humans creating a hothouse world?

Perhaps they would, if they’d seen what these conferences have become. While ‘jaw jaw’ remains better than ‘war war’, there is no doubt that these climate conferences have become a parody performance of international negotiations. Children sang and presented flowers; the UN Secretary General Antonio Gutierrez restated the ‘code red’ call he’s been making for a while now; John Kerry stated publicly that world leaders were on a ‘collective suicide mission’, which, given that he’s the United States Ambassador on Climate Change, should have made more headlines, but was instead greeted with a collective ‘meh’. ‘Interactive’ dialogue sessions promised to open up the agenda, but invited only pre-selected agencies all of whom said, again, what they’d been saying for years.

This is no way to have a conversation.

Over two days, ministers and civil servants from every UN country and associated organisations make five minute speeches on the main stage designed to appeal to the media back home rather than make any breakthroughs in the room. There are the usual obligatory selfie walls and hordes of professional sustainability experts in suits taking advantage of them to burnish their green international network credentials. Civil society groups have to fight discriminatory visa systems and lack of funds to even get to the summit, only to find out that there is no access to the processes by which the summit decisions and texts are being made. The youth delegations express their now familiar (and understandable) frustration with the older generation and demand of tired, under-funded UN representatives that they ‘use their privilege’ and power to make the changes needed. It resembles nothing so much as a pyramid selling scheme, with everyone fighting to get closer and closer to a centre of power which, in the end, turns out to be illusory.

As an outsider, watching this process in Stockholm, just as I watched COP last year in Glasgow, was like watching an old world dying. You could see old institutions struggle and fail to deal with state capture by fossil fuel interests, observe exponential natural changes meet incremental policy negotiations, feel the chaotic speed of ecosystem transformations meet lock-in and predatory delay of social systems.

And yet, where there is death there is also, always, life.

All around the official event were people using the summit as an excuse to gather, as a way of using the old systems to create something new. A new generation of policy actors, youth movements, academics, unions and civil society, energised by lessons learned from COP26, gathered in informal associated events and activities. This is where the energy was, where dialogue was taking place, where people were learning from each other and naming the obstacles that needed to be overcome.

You could feel the energy in the work of the Fossil Fuel Non Proliferation Treaty movement which is creating serious alliances across countries and interests and is beginning to exert enough pressure to get commitments to fossil fuel phase-out on the formal agenda; you could see it in the brilliant legal escapades of the ‘Stop Ecocide’ movement making the case for the rights of nature and getting faith leaders around the world signed up to protecting nature. And more than energy, you could see serious, feasible new ideas emerging in the hard economic thinking mobilised by the Stockholm Resilience Centre in their new Earth4all report, which outlines concrete steps towards non-ecocidal and non-suicidal economic arrangements; and in the principled and practical work of the Rainforest Coalition demonstrating what real carbon capture actually looks like and tracing routes towards sustaining it.

What characterises many of these activities is a commitment to a different sort of conversation – to processes of unlearning, of listening, of deep attention to others in the room, of naming the hard problems and working together on them. They point the way to a new sort of conversation – one from which the organisers of future UN conferences might learn. And one which we can all begin to model and practice in each country, network or community that we are part of back home.

Net Zero Oceanographic Capability: the future of marine research

Posted on December 13, 2021March 30, 2023 by janet.crompton

Our oceans are crucial in regulating global climate and are essential to life on Earth. The marine environment is being impacted severely by multiple and cumulative stressors, including pollution, ocean acidification, resource extraction, and climate change. Scientific understanding of marine systems today and in the future, and their sensitivity to these stressors, is essential if we are to manage our oceans, and achieve the United Nations Sustainable Development Goals (SDGs). However, these systems are complex – with a vast array of interacting physical, chemical, biological and sociological components – and operate on scales of microns to kilometres, and milliseconds to millennia. To address these challenges, modern marine science spans a wide range of multidisciplinary topics, including understanding the fundamental drivers of ocean circulation, ecosystem behaviour and its response to climate change, causes of and consequences of polar ice cap melt, and the impacts of ocean warming on sea level, weather and climate. Marine scientists investigate problems of societal relevance such as food security, hazards relating to sea level rise, storm surges and underwater volcanoes, and understanding the consequences of offshore development on the health of the ocean in the context of building a sustainable blue economy. With the start of the UN Decade of Ocean Science for Sustainable Development in 2021, there is a clear motivation not only for more research, but for sustainable approaches.

However, a key challenge facing all scientists in the near future is the absolute necessity to reduce and mitigate all carbon emissions, achieving ‘Net Zero’. Among many of the high-impact pledges made over recent months, UK Research and Innovation (UKRI) have promised to achieve Net Zero by 2040. UKRI is the umbrella organisation encompassing all of the UK Research Councils including the Natural Environment Research Council, which funds the National Oceanography Centre and British Antarctic Survey to operate the large-scale UK marine research infrastructure.

Whilst marine science is intrinsically linked to Net Zero objectives since the ocean is a major sink of anthropogenic carbon and excess heat, the carrying out marine research itself contributes to the problem in question: ocean-going research vessels use considerable amounts of fossil fuels. Ship-based observations allow scientists to address global challenges, to support ocean observing networks, make measurements not possible via satellite, or in remote and extreme environments. Such observations are essential to establish a thorough picture of how the ocean is changing, and the underlying processes behind the complex interweaving of physics, chemistry, biology and geology within marine systems, but can only continue into the future if the carbon footprint of sea-going research is cut dramatically.

The Net Zero Oceanographic Capability (NZOC) scoping review, led by the National Oceanography Centre but supported by researchers from around the UK, is a groundbreaking project aimed at understanding the drivers and enablers of future oceanographic research in a Net Zero world. New technologies and infrastructure – together with multidisciplinary, international approaches, and collaborations with private and public sector stakeholders – are going to be increasingly important to advance understanding of the oceans and climate, while accomplishing Net Zero. The NZOC team are building a picture of a future research ecosystem that capitalises upon emerging technologies in shipping, marine autonomous systems (MAS) sensor technology and data science. Ships will still be an essential linchpin of a new marine observing network, to gather critical information that may not be accessible using MAS, and to enable the maximum value to be extracted from datastreams collected during oceanographic expeditions. The new Net Zero approaches have the potential to not just replace existing marine research capability with one less damaging to the environment, but also to expand and extend it, with new tools available more marine observing, new avenues of research opened up, and wider accessibility. In order to achieve its potential, the development of new systems, and adaptation and improvement of existing methodologies, must be co-designed between technologists and scientists, including modellers and data scientists, as well as those engaged with sea-going observations. Investment in an equitable, diverse and inclusive marine workforce must be considered from the beginning, with engagement in skills training for existing and future marine researchers so that scientists are primed to use the new approaches afforded by a Net Zero approach to their full potential. All of these initiatives have to deliver on their promise in a co-ordinated way and in a short timeframe. Many of them will rely upon global infrastructures and international systems that must similarly adapt at pace.

Environmental and climate scientists overwhelmingly and urgently support a move towards Net Zero. However, we cannot overstate the importance of getting the transition to Net Zero right. Whilst an ever-growing number of UK marine scientists are using MAS and low carbon options, NZOC also identified a number of case studies where achieving Net Zero will limit marine science – possibly permanently – if not addressed. These include research areas where scientists need to drill into deep rock, or carry out intricate biological or geochemical experiments and measurements. Any transition to using new methods must be managed flexibly, requiring intersection between old and new technologies, due consideration to accessibility, and verification and validation by the wider scientific community.

Achieving Net Zero is one of the most important societal goals over the next decade. We can not only maintain but also build on marine science capability – essential for meeting Net Zero targets – with equitable and fair strategic planning, co-design of new approaches, and by taking advantage of new opportunities that arise from emerging technologies.

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

Posted on October 14, 2021April 5, 2023 by janet.crompton

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 October 12, 2021April 5, 2023 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.

Innovating for sustainable oceans

Posted on June 5, 2020March 31, 2023 by janet.crompton

University of Bristol’s Cabot Institute researchers come together for the oceans’ critical decade

World Oceans Day 2020 – the start of something big

Since 1992, World Oceans Day has been bringing communities and countries together on 8 June to shine a light on the benefits we derive from – and the threats faced by – our oceans. But this year, there’s an even bigger event on the horizon. One that may go a long way to determining our planet’s future, and which researchers at the Cabot Institute for the Environment intend to be an integral part of.

From next year, the United Nations launches its Decade of Ocean Science for Sustainable Development, a major new initiative that aims to “support efforts to reverse the cycle of decline in ocean health”.

Oceans are of enormous importance to humans and all life on our planet – they regulate our climate, provide food, help us breathe and support worldwide economies. They absorb 50 times more carbon dioxide than our atmosphere, and sea-dwelling phytoplankton alone produce at least half the world’s oxygen. The OECD estimates that three billion people, mostly in developing countries, rely on the oceans for their livelihoods and that by the end of the decade, ocean-based industry, including fishing, tourism and offshore wind, may be worth $3 trillion of added economic value.

A decade to decide the future of our oceans

But ocean health is ailing. The first World Ocean Assessment in 2016 underlined the extent of the damaging breakdown of systems vital to life on Earth. As the human population speeds towards nine billion and the effects of our global climate crisis and other environmental stressors take hold, “Adaptation strategies and science-informed policy responses to global [ocean] change are urgently needed,” states the UN.

By announcing a Decade of Ocean Science, the UN recognises the pressing need for researchers everywhere and from all backgrounds to come together and deliver the evidence base and solutions that will tackle these urgent ocean challenges. At the Cabot Institute, we kicked off our support for that vision a year early by holding our first Ocean’s Workshop.

Cabot Institute Ocean’s Workshop – seeing things differently

From our diverse community of hundreds of experts seeking to protect the environment and identify ways of living better with our changing planet, we brought together researchers from a wide range of specialisms to explore how we might confront the challenges of the coming decades. The University of Bristol has recently appointed new experts in geographical, biological and earth sciences, as well as environmental humanities, who are experienced in ocean study, so, excitingly, we had a pool of new, untapped Caboteers to connect with.

During a fast-paced and far-reaching workshop, we shared insights and ideas and initiated some potentially highly valuable journeys together.

Biogeochemists helped us consider the importance of the oceans’ delicately balanced nutrient cycle that influences everything from ecosystems to the atmosphere, biologists shared their work on invertebrate vision and the impact of anthropogenic noise on dolphins and other species, and literature scholars helped us understand how the cultural significance and documentation of the oceans has evolved throughout history, altering our relationship with the seas.

We highlighted how Marine Protected Areas (MPAs) deliver mixed results based on regional differences and outdated assumptions – individual MPAs are siloed, rarely part of a more holistic strategy, and rely on data from the 1980s which fail to account for much faster-than-predicted changes to our oceans since then. Our ocean modellers noted the lack of reliable, consistent and joined-up observational data on which to base their work, as well as the limitations of only being able to model the top layers of the ocean, leaving the vast depths beneath largely unexplored. And the fruitful link between biological and geographical sciences was starkly apparent – scientists measuring the chemical composition of oceans can collaborate with biologists who have specialist knowledge about species tipping points, for example, to mitigate and prioritise society’s responses to a variety of environmental stressors.

Collaboration creates innovation

One overriding message arose again and again though – the power of many, diverse minds coming together in a single mission to engage in pioneering, solutions-focused research for our oceans. Whether it’s the need for ocean scientists to work more closely with the social scientists who co-create with coastal communities or the interdisciplinary thinking that can resolve maritime noise and light pollution, protecting our oceans requires us to operate in more joined-up ways. It is the work we conduct at this intersection that will throw new light on established and emerging problems. We can already see so many opportunities to dive into.

So, as we celebrate World Oceans Day and look ahead to a critical Decade of Ocean Science, it’s our intention to keep connecting inspiring people and innovative ideas from many seemingly disparate disciplines and to keep doing so in a way that delivers the research we need for the oceans we want.

Three history lessons to help reduce damage from earthquakes

Posted on August 23, 2019April 16, 2023 by janet.crompton

Earthquakes don’t kill people,’ the saying goes. ‘Buildings do.’
There is truth in the adage: the majority of deaths during and just after earthquakes are due to the collapse of buildings. But the violence of great catastrophes is not confined to collapsed walls and falling roofs. Earthquakes also have broader effects on people, and the environments we live in.

The United Nations Economic and Social Commission for Asia and the Pacific (ESCAP)’s second Disaster Resilience Week starts in Bangkok on 26 August 2019. Practitioners and researchers have achieved great progress in reducing disaster risk over the past few decades, but we must do more to save lives and protect livelihoods.

Can history help?

Building against disaster

Buildings are a good, practical place to start.

Material cultures offer paths to resilience. A major example is traditional building styles that reduce the threat from seismic shaking. A building is not only a compilation of bricks and stones, but a social element that reflects the cultural life of a community. This is the powerful point made by the Kathmandu-based NGO, National Society for Earthquake Technology (NSET), in a recent report on traditional Nepalese building styles.

NSET, and others working in the field, have identified features of traditional building styles that limit damage during shaking. For example, diagonal struts distribute the load of a roof and limit damage during earthquake shaking.

This is important because parts of falling buildings often kill people.

Nearby, in the Himalayan kingdom of Bhutan, the royal government is investigating the earthquake-resistant features of traditional rammed-earth buildings.

In fact, seismically-appropriate building styles have evolved along similar lines across a huge Eurasian arc of tectonic unrest, from Italy to Kashmir.

But in most countries, population pressure and the use of cheap, unreinforced concrete construction in growing towns and cities has crowded out traditional construction methods.

Reducing disaster risk always means weighing costs in the present against potential protection in the future. Recovering or encouraging traditional methods is potentially cheaper than enforcing modern seismic engineering.

Long-term health impacts

Focusing only on buildings, though, neglects other important aspects of large earthquakes. These shocks do not only shake buildings down, but can dramatically re-shape landscapes by causing huge landslides, changing the level of water in rivers and leading to flooding.

History shows that these changes can hurt people for months or years after the rubble of buildings have been cleared and reconstruction has begun.

For example, a giant (8.4 Mw) earthquake struck northeast India in 1897. Its epicentre was near Shillong, in the borderlands between British India and China. Luckily, the quake happened in the afternoon, so most people were out of doors. The official death toll – the number of deaths that the colonial government attributed directly to the earthquake – was around 1,500.

Yet officials also thought the poor health conditions that followed the earthquake and the substantial floods that it caused were largely responsible for a major cholera epidemic which killed 33,000 people in the Brahmaputra Valley during the same year. That is twice as many as the previous year.

From the available evidence, it is not yet clear how directly the earthquake and the cholera deaths were linked, but other examples saw similar scenarios. In 1934, another major (8.0 Mw) quake devastated parts of Nepal and North India.

This time, the official death toll in India was around 7,500, but again many more people died from related health complications over the following years. In one district in northern Bihar province, an average of 55,000 people died of fever every year over the next decade. In other areas, malaria was unusually prevalent over the same period.

Government reports held secondary effects of the earthquake responsible for the high death rate.
Events that happened long ago therefore demonstrate the complexity of earthquakes’ impacts, even on the relatively straightforward question mortality. Studying them highlights the need to focus present-day disaster responses on long-term health implications.

Of course, this says nothing of earthquakes’ less concrete, but very important, impacts on social structures, community life, governance or the economy.

History in action

In some cases, historical researchers are contributing directly to initiatives to reduce risk from natural disasters.

Hurricane Katrina showed in 2005 that low-lying New Orleans is terribly vulnerable to storm surge and flooding. Craig Colten, a historical geographer at Louisiana State University, is working with a team of scientists to find solutions by raising the height of the ground in parts of the city while adding forested wetlands on its north shore. Colten is studying analogous historical efforts in other American cities – flood-control measures in nineteenth-century Chicago and responses to hurricanes in Galveston, Texas, around 1900 – as well as examining previous proposals for creating buffers between New Orleans and the sea.

These historical examples provide evidence of what works and what does not. They also highlight the politics of decision-making that help determine whether local communities will support landscape engineering projects.

The international frameworks governing disaster risk reduction such as the Sendai Framework for Disaster Risk Reduction and the Sustainable Development Goals understandably focus on the present, not the past. Historians need to join the conversation to show practitioners that lessons from the past can help build resilience in the future.

Localising the Sustainable Development Goals for Bristol

Posted on February 20, 2018April 4, 2023 by janet.crompton

In 2015 the 17 UN Sustainable Development Goals (SDGs) were ratified by 193 of the UN member nations. These goals set ambitious targets to address worldwide issues of sustainable development, such as social inequality, responsible and inclusive economic development and environmental protection. They were created for everyone, everywhere and have been described as ‘the closest thing the world has to a strategy’.

Who will be responsible for ensuring we achieve these goals and how will they be achieved?
In the realm of international agreements, national governments have traditionally been responsible for local implementation. But a combination of profound global demographic shifts and a sense that national governments are increasingly incapable of tackling complex global challenges due to domestic political wrangling has given rise to a global movement to place cities at the heart of efforts to tackle both local and global challenges. This movement, which is coalescing around a constellation of city-to-city networks (such as ICLEI, C40 and the Global Parliament of Mayors), is now grappling with the challenge of ‘localising the SDGs’. How can we usefully translate this global agenda into local practice in a way that meaningfully transforms lives?

This is the question we are working to answer through a new University of Bristol funded project on Localising the SDGs for Bristol, in partnership with the Bristol Green Capital Partnership (BGCP), Bristol City Council and Overseas Development Institute (ODI).

Bristol is a city of great wealth and has strong environmental credentials as the former European Green Capital in 2015. The city is also home to a vibrant cluster of ‘green economy’ companies and environmental charities. However, Bristol also faces many challenges. Homelessness is twice the national average; nearly 16% of Bristolians live in England’s 10% most deprived areas; and Bristol health outcomes are worse than the national averages for many indicators (e.g. life expectancy, suicide, childhood obesity, smoking).

These are precisely the kinds of challenges that the Sustainable Development Goals are encouraging us to confront and tackle by 2030. Importantly, ‘sustainability’ isn’t just about the environment; it is also about building a prosperous and inclusive economy that leaves no one behind. Inclusion, equality and opportunity are essential to achieve sustainability.

Our research seeks to identify and support mechanisms for embedding the SDGs in local planning and governance processes by engaging with a wide range of stakeholders in the city.

Bristol City Council, a pivotal stakeholder is currently working to bring partners together for a new One City Plan. This Plan seeks to use the collective power of Bristol’s key organisations to achieve a bigger impact by supporting partners, organisations and citizens to help solve key city challenges and improve the lives of Bristolians across the city. The core themes behind this plan align with the SDGs and it provides a great opportunity for Bristol to lead nationally and internationally on the SDGs. As this plan comes together we aim to input insights from other cities around the world that are also working to implement the SDGs.

Los Angeles Mayor Eric Garcetti committing to the SDGs for LA

To that end Allan Macleod, the Cabot Institute SDGs Research & Engagement Associate, recently attended the Global Ambition–Local Action Conference hosted by the Occidental College in Los Angeles. The conference focused on what cities can and are doing to address the SDGs and how they can mobilise data and resources to further their work. It was a very informative experience, but was it was also inspiring to see how Bristol compares to some of the largest and most important Global Cities. It was clear that Bristol has developed a solid foundation for SDG localisation and has a real opportunity to become global leader in implementing the SDGs. In doing so the city will both confront the need to develop a more inclusive and sustainable local economy while contributing to global efforts to tackle transboundary problems together with other cities.

This is a particularly exciting time to be working collaboratively on implementing the SDGs in Bristol as the city will be hosting two major conferences in 2018: the Data for International Development Festival at the end of March and the Global Parliament of Mayors Annual Summit in October. Both these events provide Bristol with an opportunity to showcase its leadership and demonstrate its credentials as an important international city that is working to improve the lives of all its citizens.

What experiences do you have of the SDGs abroad or in Bristol? Do you have an ideas or lessons that can be applied to Bristol? If you have any further questions or comments, feel free to get in touch at Allan.macleod@bristol.ac.uk.

Interests in Aid and Development: a talk with Myles Wickstead

Posted on March 1, 2017April 5, 2023 by janet.crompton

Ever wondered what a career in aid and development is like? Or how the world’s current development programmes came into being? Look no further than this blog on Myles Wickstead who gave a Cabot Institute lecture and short interview on his reflections and experiences on a colourful career in aid and development.

Among Wickstead’s notable achievements are a position as head of British Development Division in Eastern Africa, coordinating a British Government White Paper on eliminating world poverty and now being an advisor to the charity Hand in Hand International.

An audio recording of Myles lecture can be found above. His talk focussed largely on the inception of the building blocks of international development; the UN, the World Bank and the International Monetary fund. He began by turning back time towards the end of the second World War, in which the atmosphere of global reconciliation bred the need for trans-border institutions such as the UN that had the oversight necessary for peace to prevail.

Many years later, the UN decided to introduce development goals with the aim of reducing global poverty within a given time frame. The first of these was the Millennium Development Goals which were drafted in the UN head quarters with little external solicitation. In fact, Wickstead reminisced that environmental goals were almost completely overlooked and only added when a member of the committee ran into the director of the UN environment department on the way to the copier room…

Wickstead went on to add that a large parts of the Millennium goals were generally quite successful although there was still plenty of scope to be more inclusive. He also dwelt on the new Sustainable Development Goals drafted by the UN in 2015 and the Paris climate summit which, Wickstead claims, represent a much more integrated approach to propel international development into the future.

Below is my interview with Myles in which I question him on his talk and ask him about his career in aid and development:

You mentioned a fair bit in your talk about the importance of tying in environment sustainability with aid and development. How do you see that working in practice in a developing country when sustainable practices can be sometimes be quite anti-economic?

Yes, the two things are brought together in the Global Goals for Sustainable Development agreed in New York in September 2015. Let’s take an example of a country that’s well-endowed with forest resources. They could get rich quickly by chopping down the trees and selling the wood. You can’t expect those countries to simply say ‘we are not going to chop our forest down’. Firstly you need them to realise that for the long-term sustainability of their country they need to preserve the forest. But second, because maintaining the forests helps protect us all from climate change they rightly expect some compensation from the international community to do so. There are (albeit imperfect) mechanisms in place for this. Despite this I do, on the whole, think they are being successfully implemented: take Brazil for example.

There are also examples where – often without the consent of the government – indigenous forests are being cut down to make way for palm oil plantations, with devastating consequences not only for the trees but the wildlife. In these situations, governments need to be encouraged to take firm action against the individuals or companies concerned, again with support from the international community as and if appropriate.

I work on volcanic hazard in Ethiopia and one of the things I’ve noticed is the more wealthy urban areas are developing fast with an expanding middle class, but the more rural areas are still subject to a lot of extreme poverty. What part should external aid play in helping this wealth filter down?

It’s a very important question and one I touched on when talking about the Millennium Development Goals (MDGs) which were in place from 2000-2015. That period saw extraordinary progress, including halving the proportion of people living in absolute poverty, but many people (for example, those with disabilities or from ethnic minorities) were left out. It is also the case that urban areas, with generally better infrastructure and more job opportunities, tended to make faster progress. A lot of people in rural areas were in very much the same position in 2015 as in 1990. Within Ethiopia, a combination of rapid economic growth – supported both by investment and aid – and good policies mean that the benefits are now being felt more widely.

The role of Chinese investment in infrastructure, particularly roads, has I think been quite a positive one. The Government of Ethiopia has a very clear five year growth and investment plan and they expect their partners to deliver; I remember one case of former Ethiopian Prime Minister Meles requiring a Chinese company to rebuild a road they had just built as it was not up to standard; I am sure they were equally exacting of other companies from other countries. Not all African governments have that kind of determination but on the whole I think Chinese engagement has been a good thing. And the fact that Africa was largely unaffected by the global recession following the crash of 2008 was not only because it was not as connected to the international financial system as other parts of the world, but also because China and other countries in Asia continued to buy its raw materials.

What influenced your decision to have a career in Aid and development?

I had lived and travelled overseas a little. My father was a marine biologist and as a technical expert worked for the predecessors of DFID and lived and worked overseas in places like Singapore, Tanzania, and Jamaica. So I probably got some of the wish to live and work overseas from him – though alas didn’t inherit the science gene, which passed me by!

I went through the civil service fast stream process, and having successfully negotiated that had to make a choice about which Department I wanted to join. It was then the Ministry of Overseas Development; a few years later became the Overseas Development Administration of the FCO; and in 1997 became a fully-fledged Department of State with its own Cabinet Minister. Interestingly, DFID remains the most popular choice of all government departments for fast-steam applicants.

Is there a defining moment in your career you want to mention?

I have been extraordinarily lucky in the choices that I have made – or have been made for me – in terms of where I was at particular time. To have had the chance to run a regional office in Africa; to have been on the Board of the World Bank; to have worked closely with Ministers both as a Private Secretary and in coordinating the 1997 White Paper (the first in 24 years); and to be Ambassador to Ethiopia and the African Union – it was a huge privilege (and very hard work!) to be given these responsibilities. I ran the Commission for Africa Secretariat in 2004/5, and I suppose one of the great moments was going to present a copy of the Commission’s Report ‘Our Common Interest’ in 2005 to Nelson Mandela.

Someone asked earlier today- how do you keep positive despite the gloomy state of much of the world? My answer would be that the world has made extraordinary progress over the past quarter of a century in pulling people out of poverty, and that we have a real chance of completing the task, in line with the Sustainable Development Goals, by 2030. Of course there have been setbacks along the way, and there will be more – conflict and environmental challenges to name but two. But with political will, and by maintaining a positive focus, I believe we can aspire to a better world both for ourselves and for future generations.

Your planet needs you!

Posted on April 14, 2014April 19, 2023 by janet.crompton

We are under attack. Our assailants threaten to kill millions of people, destroy our homes and wipe out our crops. Who are these fiends?

Us.

The latest report from the Intergovernmental Panel on Climate Change (IPCC) focusses on how we can stop runaway climate change before it’s too late. Despite our “best efforts”, anthropogenic greenhouse gas emissions have continued to increase at an alarming rate. The IPCC estimates that without any additional effort to reduce emissions, we’re looking at a rise in temperature of between 3.7 and 4.8°C by 2100, although variability in the effects of climate change mean the rise could be as high as 7.8°C. Anything over 2°C means we risk runaway climate change with catastrophic effects felt around the world.

A call to action

The UK energy secretary Ed Davey responded to yesterday’s IPCC press conference by stating,

“we need a worldwide, large-scale change to our energy system if we are to limit the effects of climate change”

and called for an international effort to reduce carbon emissions by 2015.

The question is, are politicians willing to put in the effort needed to reduce emissions by 40-70% in the next couple of decades? It’s hard to put a price on the cost of mitigation, but as Professor Ottmar Edenhofer, co-chair of the IPCC team, stated “Climate policy is not a free lunch”. His colleague Professor Jim Skea was more optimistic, saying that,

“it is actually affordable to do it and people are not going to have to sacrifice their aspirations about improved standards of living”.

That’s the kind of thing that politicians like to hear.

Change doesn’t happen unless something dramatic happens to force us to act. The increasing frequency of extreme weather events doesn’t seem to be working, so what would? As the IPCC brief states, “Emissions by any agent (e.g. Individual, community, company, country) affect other agents”. We need to invoke some Blitz mentality; we ARE facing a deadly enemy and we ALL need to do our part to stop it.

How to mitigate climate change

The IPCC used 10,000 scientific references to ensure that their models are properly founded in science and all the uncertainty that entails. The IPCC defined mitigation as “a human intervention to reduce the sources or enhance the sinks of greenhouse gases”, and look at a range of scenarios to find the most effective and efficient methods.

The report particularly favoured low carbon energy sources as a major way to reduce emissions, using natural gas as a transition fuel into renewable energies. Encouragingly, renewable energy comprised over half of all new electricity-generating developments globally, with wind, hydro- and solar power leading the way. The costs of renewable energies are falling, making them viable for large scale deployment in many areas, and Professor Skea enthused that

“Renewables are going to be ubiquitous no matter which part of the world you look at”.

Cities will play a big part in reducing CO2 emissions too; a combination of better urban planning to incorporate public transport and compact walkable city centres will be vital. The report also recommended high speed rail networks between cities to reduce short haul air travel and its associated high emissions.

Replanting forests will be an important way to remove CO2 from the atmosphere. Plants take in CO2 for use in photosynthesis, but can also be used to remove pollutants from the air and soil, as well as preventing soil erosion and providing important habitats for other plants and animals.

It is important for all nations that mitigation does not mean a halt to economic development. Dr. Youba Sokona, IPCC team co-chair, said, “The core task of climate change mitigation is decoupling greenhouse gas emissions from the growth of economics and population”. This will be the main challenge for governments around the world, but the overwhelming message from the IPCC is that mitigation is affordable, whilst doing nothing is not.

Social justice

There has been an undercurrent of unease alongside the IPCC report; the sticky question of who, exactly, is going to pay for this mitigation? A few days before its release, pressure from unspecified developed nations led to the removal of a section in the IPCC report stating that developing countries should receive billions of dollars a year in aid to ensure that they grow their economies in a sustainable way.

The argument centres on whether developing nations should have the right to exploit fossil fuels to expand their economies, as developed countries were able to do. Dr. Chukwumerije Okereke, one of the lead authors of the report, said that this “is holding them down from developing”, believing that “this is reinforcing historical patterns of injustice and domination”. I would argue that with the impacts of climate change predicted to affect those in developing countries most drastically, perhaps we should adopt the mentality that we are all in this together and help each other to overcome the problem.

Act now

The take home message from the IPCC is that if we act now, we can probably prevent hitting the 2°C temperature increase that would have disastrous consequences for us all. The mitigation strategies suggested are affordable and certainly cheaper than dealing with the consequences of climate change. Will politicians and all the rest of us do our parts to drastically reduce carbon emissions? Only time will tell. A lot of hope rests on the 2015 United Nations Climate Change Conference, which is hoped to yield a global agreement on climate to avoid passing the 2°C safety threshold.

Cross your fingers and turn off your lights.
