Bristol Geographers appear in The Times and condemn divisive Brexit rhetoric

The following text comprises a longer version of a Letter to the Editor that appears in print and online in The Times. The letter, signed by over 85 members from of the School of Geographical Sciences expresses our dismay and disillusionment with the recent divisive rhetoric from the government regarding foreign workers and an inclusive society.

Further, we are concerned that this rhetoric is already acting as a detriment to our university’s values, and the research and teaching we do.

The letter starts here:

“As a nationally and internationally recognised research and teaching department, we echo Lord Rees’ recent comments to express our deep concern at the divisive and ‘deplorable’ rhetoric during discussions about Brexit and immigration at the recent Conservative party conference. This rhetoric does not reflect the values we aim to uphold in our university and discipline, nor the diversity of feelings in the country. We are dismayed, further, that our Prime Minister, a former student of geography, seems to have forgotten our subject’s core teachings and values.

We are ‘citizens of the world’. Our department’s research, teaching, and study ranges across diverse fields: from financial institutions to flooding; from philosophy to parliamentary boundary reform; from colonialism and biogeochemistry, and all the planetary processes in between. We come from over 19 different countries, and virtually every populated continent. We come from everywhere. And we contribute to numerous global and local initiatives that seek to make our world a better, healthier, happier place.

What unites our diverse scholarly work is the recognition that how we make sense of the Earth – how we ‘geo-graph’ it – matters. How we understand our relationships to the Earth and each other matters for addressing issues affecting our shared planet, equitably and honestly. For this reason, we highlight our responsibility to one another and the many complex forces that make life possible; we recognise and value the many who make us, always, more than one.

Thus, we stand behind all of our staff and students who come from all corners of the world, and who contribute, as international citizens, to the strength of our department and its impacts locally, nationally, and globally. International staff and students now feel very insecure about their futures here. While we will do everything we can to protect their work and contributions, we hope the government will make clear that their futures – and those of our colleagues across the UK – are under no threat.

The Nikki Project: Designing a rainwater harvesting system for an African health centre

Last summer three Engineers Without Borders (EWB) members conducted a six week recce on water supply in Nikki, Benin, last summer. After building contacts with local engineers, schools and hospitals, sourcing handwritten archived data, and finding many interesting answers to our questions, we are now working hard on designs for a rainwater harvesting system and planning this summer’s work. This blog is about our project, why it’s important and how we’re going about it.

Main high street in Nikki, northern Benin.

The Nikki Project aims to address water supply problems in the small district of Nikki, Benin. A big layer of granite near to the ground surface means there is only a seasonal water table. This means the Benin government’s method of borehole water supply, which works for the rest of the country, does not work here. Citizens are given a few hours of water supply per day (at the best of times). This water is cut until 2 am and rarely lasts past 5 am; certainly not ideal for schools and hospitals that need water for treatment during the day. Instead, citizens turn to private boreholes, wells and at the worst times, an untreated lake outside the city.

Map showing Benin at the bottom of the image.

Engineers Without Borders Bristol are partnered with a Spanish charity, OAN International, who identified this problem two years ago and asked EWB Bristol to help tackle Nikki’s water supply issues. Last summer our aim was to build a partnership with a local service, who we trusted to maintain the system in our absence and who we thought would be a good working partner to trial our designs.

Back in the UK about 25 of us meet every week to work on this project. Our main task this year has been the design of a rainwater harvesting system for a small health clinic. This clinic was established by two male nurses, funded from the money they earned working for the Benin national health service. They run the clinic by working 12 hours shifts each, with dedication and fantastic vision. Like all health services in Benin the centre charges for their services, but unlike the hospitals makes no profit from the sale of medicines. The hygiene measures taken were extraordinary for Benin; to paraphrase a Spanish medic volunteer, this was ‘the first time [he] has seen a Benin child being told to wash their hands’. The clinic deals, amongst other things, with malaria and pregnancy: the two biggest causes of death in the area.

The health clinic that EWB are working with to provide a rainharvesting water supply.
The EWB Bristol team surveying the health centre site in Benin.

Our rainwater harvesting solution will consist of a large 90,000 litre storage tank, a water treatment system, and a small water tower to gravity feed the water into existing taps in the clinic. The tank will collect water during the rainy season and store it safely until the dry period when no water is available from the government supply.

This type of system has become very successful and widespread elsewhere in Sub-Saharan Africa, and if successful this type of system could be expanded to suit more clinics or schools in the region. We chose to work with this health centre because of the nurses’ incredible dedication to their cause; before we had finished explaining the concept, they had already started discussing how they would start saving up for it. While contributing to the materials is certainly something we are discussing as the cost of materials and labour is not high in Benin, a sense of ownership is key to the system being maintained properly and thus being a success.

An example of pipes not properly attached and fallen down in the wind leading to an abandoned RWH tank. This tank was built 2005. The current staff have no recollection of it ever functioning.

We are still exploring design options for our rainwater harvesting system:

  • Should the pump be manual or electric (practical in everyday or with a higher risk/cost of replacement)?
  • Should the water be chlorinated in the tank or after the tank or both? Is it worth the money if it will be chlorinated again anyway?
  • Would someone prefer a monthly job or a daily job in maintaining the water treatment system? If we use a Bernoulli chlorinator will it make chemical concentrations easier or more difficult to control? Possibly easier if they understand and potentially disastrous if they do not?
  • What construction materials are best? This needs to be considered with respect to practicality, local skill availability, durability and what is culturally accepted.
We are affiliated by Engineers Without Borders UK who are there for advice, provide pre-departure training for volunteers and offer insurance while out there. We have gratefully received £2,000 from the university Alumni Foundation and £11,000 from the Queen’s School of Engineering to support the project and the lab testing we’re planning before the trip this summer. We will be blogging and updating our website as the project progresses.

Why is the UK interested in volcanoes? We don’t have any of our own!

Eruption column from the explosive phase of the Eyjafjallajokull eruption drifting over a farm  – image by Bristol volcanologist Susanna Jenkins
The University of Bristol’s volcanology group has been awarded the Queen’s Anniversary Prize for its contribution to research excellenceThe Queens Anniversary Prize is the most prestigious form of national recognition an institution can receive. When I tell members of the public that, not only am I a volcanologist, but that I am part of the one of the largest and most successful volcanology groups in the world, the first reaction is always surprise: ‘Why is the UK interested in volcanoes? We don’t have any of our own!’

They are right of course, the Bristol volcanology group spends its time travelling all over the world to address volcanic risk in many countries, from the first to the third world. When one looks back on volcanic eruptions in recent history, especially the big, memorable ones like Mount St Helens, Eyjafjallajokull and Montserrat one realises that Bristol volcanologists were there at every stage.

There are, of course, many layers to handling a volcanic crisis. First there’s initial monitoring; will this volcano erupt at all? Often this involves going to volcanoes that have been little studied in remote places, or monitoring them from satellites: something which Bristol volcanology has taken in its stride, by trailblazing projects on understudied African volcanism.

Then there’s handling eruptions as they happen. Who will be affected? What are the primary risks? How should we respond to the media? Bristol has a glowing history of aiding in volcanic crisis by supplying the information when the world needs it. During the 2010 Eyjafjallajokull ash and aviation crisis, Bristol led the way in supplying expert opinion on managing the situation.

Still there is no rest for our volcanologists. Afterwards there’s the post-eruption work: Working out what made the volcano erupt and understanding the physical processes surrounding an event. How does it fit into the wider setting? Are the volcanoes linked? These questions have been asked and answered by our volcanologists who have also reached out to form a global database with other institutions. This has resulted in more cohesion in the community, and a greater understanding of how volcanoes interact.

A wealth of different specialities have populated the group since it was started by Professor Steve Sparks  including petrologists, geophysicists and geochemists. It is a result of this diverse environment that Bristol has been able to excel in so many areas. With natural hazards occurring on a near-daily basis, it’s safe to say the group has played its part in reducing the uncertainty of volcanic hazard across the globe.  The Queen’s Anniversary Prize is an amazing recognition of the work that has been done over the years and a well-deserved reward for the hard work of the Bristol volcanologists.

COP21 reflections: What next for Bristol?

As you might imagine, especially given the focus on cities, it was an exciting two weeks for Bristol.  The City was everywhere.  In Paris with Anne Hidalgo; with its resilient partners in the Rockefeller 100 Resilient Cites group; representing smart city investment on behalf of Eurocities; hosting a Bristol Green Capital display in the Green Zone; and also sponsoring the linked Cities and Regions Pavilion nearby. Our city is going global in reputation, stature and visibility . This is a great achievement for our city and a great opportunity.  We are viewed as ambitious, eager to embrace the new economy, and supportive of technology and creativity.  We also had hundreds of people come to our stand and ask about moving to Bristol – the best and the brightest of the next generation also see Bristol as a place to bring their talents.

We cannot be complacent, however.  A corollary to the message of ambition was that a new race to lead in the global energy transformation has already begun; the cities, regions and nations that drive the agenda will prosper and those that do not will be left behind.  Those that move slowly will eventually benefit from new innovations, but the skills, businesses and IP will have moved elsewhere. Bristol is one of the leaders but it will have to fight to remain so.

In this sense, it is exciting to see the European Green Capital year ending with some exciting consolidation around major themes. Among these are partnership, resilience and health and well-being.  Here, however, I want to focus on three others; two where our efforts are consolidating into deeply impressive and globally distinctive initiatives and a third where we need to do better.

One of the major themes of this year has been energy use, and Bristol’s Transformative Action Plan, The Bristol Billion, will dramatically accelerate residential energy efficiency. This TAP, by virtue of its concrete targets, themselves underpinned by the University of Bristol Mini-Stern Study and the STEEP Project, was a foundation to the ICLEI and Mayors’ argument that cities do have the appropriate ambition.  The Bristol Billion will work in tandem with the new City Council-owned Energy Company, launched on 1 November 2015. The company will initially focus on using its profits to improve energy efficiency and tackling fuel poverty, and it will eventually offer a renewable tariff. Crucially, the Company intends to complement rather than compete with existing and emerging community energy initiatives, such as that explored on 14 December 2015: Towards a Smart Energy City: mapping a path for Bristol.

Another emerging theme is the role of the Smart City, whether it be Bristol is Open or the Bristol Brain (Bristol’s other Transformative Action Plan). I have written about these extensively and won’t repeat that here!  Ultimately, however, I do not think these will be about techy solutions to our cities’ problems – although that will certainly be part of the smart, future city.  I think and I hope that smart city technology will yield ‘smarter’ citizens and ‘smarter’ leaders allowing us to make much harder – and smarter – decisions. What I mean by that is that smart technology can empower people to make their own observations, to be directly involved in the exploration and learning journey of their home and city.  We will be able to monitor electricity usage and heat loss in our own homes; urban planners will be able experiment in a virtual world to fully explore the implications of their decisions.  Ultimately, this technology could provide a place where many people can come together and discuss their future city. This is Colin Taylor’s vision for the UKCRIC-funded Collaboratory.

There are many opportunities that will come from addressing climate change; but the full road to decarbonisation will be challenging, requiring hard choices and compromises.  In Bristol, home improvements will create jobs, fight fuel poverty, save money, improve health and reduce emissions – a win win win win win proposition! A Bristol transportation system that produces no carbon dioxide will be much harder to achieve.

To me, finding the pathway to that political consensus – and the inclusion that demands – is probably the third major theme of 2015.  And not because we did it terribly well.  Some successes include the fantastic new Sustainable Education Programme.  And I think we did okay in the Cabot Institute by putting on many events and getting out into the city to educate or inform, often with artists or other groups. Local initiatives have also raised awareness.

But we have not truly entrained new and diverse groups in a new dialogue; instead it feels as if the old dialogue has just had the volume turned up.  That’s fine but we can do more. This issue was the focus of the meeting I alluded to in the first blog and the subject of Helly’s blog on behalf of Ujima Radio.  Convened by Policy Bristol, the Green Capital Partnership, Ujima and ourselves, the meeting explored some of the challenges we face.  I’ll revisit this in the New Year, but I’d like to share a few initial thoughts.

We listen to each other but often do we understand. That is perhaps inevitable as we come from different backgrounds; nonetheless, we have to invest the time to really understand the wants, needs and (most of all!) capabilities of the many groups in Bristol.

Minority groups are invited to events but rarely given the opportunity to set the agenda. This must change.

Different groups have their own suggestions and ideas, often arising from our diverse cultures.  We need to pivot from preaching about solutions to sharing ideas.

Building mutual trust in one another – trust in our fellow citizens and our leaders – must be a focus of 2016 as we build on our Green Capital legacy and look to the future.  I do not have an easy answer to that; no one does.  But perhaps some small, positive steps together can help to build that trust.

COP21 daily report: The need for innovation (but do not call it innovation)

Cabot Institute Director Professor Rich Pancost will be attending COP21 in Paris as part of the Bristol city-wide team, including the Mayor of Bristol, representatives from Bristol City Council and the Bristol Green Capital Partnership. He and other Cabot Institute members will be writing blogs during COP21, reflecting on what is happening in Paris, especially in the Paris and Bristol co-hosted Cities and Regions Pavilion, and also on the conclusion to Bristol’s year as the European Green Capital.  Follow #UoBGreen and #COP21 for live updates from the University of Bristol.  All blogs in the series are linked to at the bottom of this blog.

—————————–


For the past two days, a delegation of us have been representing Bristol City Council and a group of Bristol businesses at the Sustainable Innovation Forum (SIF) at Paris.  Our group included Bristol Mayor George Ferguson, who spoke on Tuesday; Amy Robinson, of Low Carbon Southwest and the driver behind the Go Green business initiative; Bristol City Council representatives Stephen Hillton and Mhairi Ambler; and Ben Wielgus of KPMG and Chris Hayes of Skanska, both Bristol Green Capital sponsors.

This was the COP21 ‘Business event’ and aspects of this have been rather sharply targeted by Paris activists. There is a legitimate question of whether corporate sponsors are engaging in greenwashing, but this was not my perception from inside Le Stade de France.  There were some major fossil fuel dependent or environmentally impactful companies in attendance, but they seemed genuinely committed to reducing their environmental impact.  Their actions must be transparent and assessed, and like all of us, they must be challenged to go further. This is why it was fantastic that Mindy Lubber, President of Ceres, was speaking. Ceres is a true agent of change, bringing a huge variety of businesses into the conversation and working with them to continually raise ambitions.

The majority of these businesses, just like those that attended Bristol’s Business Summit in October, are clearly and objectively devoted to developing new technologies to address the world’s challenges,. Whether it be new solar tech that will underpin the PVC of 2050 or innovative new ways to deploy wind turbines cheaply and effectively in small African villages, it is no longer ‘business’ that is holding back climate action and in many cases they are leading it.

And we need them to do so.  We need them to develop new products and we need them to be supported by government and Universities.  We need them because we need new innovation, new technology and new infrastructure to meet our environmental challenges.

One of the major themes of the past two days has been leadership in innovation, an ambition to which the University of Bristol and the City of Bristol aspires – like any world-class university and city.  We have profound collective ambitions to be a Collaboratory for Change. These are exemplified by Bristol is Open, the Bristol Brain and the Bristol Billion, all endeavours of cooperation between the University of Bristol and Bristol City Council and all celebrated by George Ferguson in his speech to the SIF attendees yesterday.

This need for at least some fundamentally new technology is why the Cabot Institute has launched VENTURE. It is why the University has invested so much in the award-winning incubator at the Engine Shed. It is why we have devoted so much resource to building world-leading expertise in materials and composites, especially in partnership with others in the region.

We do not need these innovations for deployment now – deployment of already existing technology will yield major reductions in our carbon emissions – but we need to start developing them now, so that we can achieve more difficult emissions reductions in 20 years.  Our future leaders must have an electrical grid that can support a renewable energy network. Our homes must have been prepared for the end of gas.

And we will need new technology to fully decarbonise.

We effectively have no way to make steel without burning coal to melt iron – we either need new tech in recycling steel, need to move to a post-steel world, need to completely redesign steel plants, or some combination of all three.

We will need new forms of low-energy shipping. Localising manufacturing and recycling could create energy savings in the global supply chain.  But we will always have a global supply chain and eventually it must be decarbonised.

Similarly, we will need to decarbonise our farm equipment.  At heart, I am still an Ohio farm boy, and so I was distracted from my cities-focus to discuss this with Carlo Lambro, Brand President of New Holland.  Their company has made some impressive efficiency gains in farm equipment, especially with respect to NOx emissions, but he conceded that a carbon neutral tractor is still far away – they require too much power, operating at near 100% capacity (cars are more like 20-30%).  He described their new methane-powered tractor, which could be joined up to biogas emissions from farm waste, but also explained that it can only operate for 1.5 hours.  There have been improvements… but there is still a long way to go. I appreciated his engagement and his candor about the challenges we face (but that did not keep me from encouraging him to go faster and further!).

Finally, if we really intend to limit warming to below 2C, then we will likely need to capture and store (CCS) some of the carbon dioxide we are adding to the atmosphere. Moreover, some of the national negotiators are pushing for a laudable 1.5C limit, and this would certainly require CCS. In fact, the need for the widespread implementation of such technology by the middle of this century is explicitly embedded in the emissions scenarios of IPCC Working Group 3. That is why some of our best Earth Scientists are working on the latest CCS technology.

Unfortunately, CCS illustrates how challenging innovation can be – or more precisely, as articulated by Californian entrepreneur Tom Steyer, how challenging it can be to develop existing technology into useful products. The CCS technology exists but it is still nascent and economically unviable.  It must be developed.  Given this, the recent cancellation of UK CCS projects is disappointing and could prove devastating for the UK’s intellectual leadership in this area.  The consequences of this decision were discussed by Nicola Sturgeon in a panel on energy futures and she renewed Scotland’s firm commitment to it.

This issue exemplifies a wider topic of conversation at the SIF: social and technological innovation and development requires financing, but securing that financing requires safety.  Skittish investors do not seek innovation; they seek safe, secure and boring investment. And SIF wrapped up by talking about how to make that happen.

First, we must invest in the research that yields innovations. We must then invest in the development of those innovations to build public and investor confidence.  Crucial to both of those is public sector support. This includes Universities, although Universities will have to operate in somewhat new ways if we wish to contribute more to the development process. We are learning, however, which is why George Ferguson singled out the Engine Shed as the world’s leading higher education based incubator.

Second, and more directly relevant to the COP21 ambitions, businesses and their investors need their governments to provide confidence that they are committed to a new energy future.  It has been clear all week that businesses will no longer accept the blame for their governments’ climate inaction.

Instead, most businesses see the opportunity and are eager to seize it. As for the few businesses that cling to the past? Like all things that fail to evolve, the past is where they shall remain.  The new generation of entrepreneurs will see to that. Whether it be the new businesses with new ideas or the old businesses that are adapting, the new economy is not coming; it is already here.

———————————

I started pondering this opening blog, the first in our Bristol at COP21 series, on Friday morning, while walking from the St Werburgh’s Community Centre back to the University.

It was a reflective walk. The  previous evening, Bristol’s COP21 team met at Brunel House to talk logistics, covering everything from travel, to security, to the main messages Bristol would want to share with the rest of the world.  All of this had come at the end of a whirlwind month of events and announcements.  In November, we had already hosted George Marshall and Jonathan Porritt (with the National Union of Journalists and Festival of Ideas), celebrated our fifth birthday, and discussed what we will achieve in the next five years with our new VC and in a rapidly transforming university.  The previous week had seen the Festival of the Future City, at which we presented some of our findings from the year on Bristol’s climate challenges, its future resiliency, its nature and connection to the countryside, and the new governance and financial structures needed to achieve transformative change.

The interactive Bristol Data Dome had opened on 18 Nov, the first in the UK and part of the rollout of Bristol Is Open.  The City’s Sustainable Education programme launched, and the Shaun the Sheep app that underpins it won the ‘App with a Purpose’ prize.  Bristol City Council launched its own Energy Company, only the second in the UK.  George Ferguson gave his annual lecture in the Wills Memorial Building, at which he announced his ambition for an up to £1 billion investment in a citywide urban retrofit to increase energy efficiency and tackle fuel poverty (a plan partially based on our mini-Stern review of Bristol as a Low Carbon City).  And of course, we are headed to COP21, where Bristol will co-host the Cities and Regions Pavilion with Paris.

And despite all of these announcements and achievements, the year feels incomplete.  The meeting in St Werburgh’s, co-sponsored by ourselves and some great partners, thoughtfully examined whether the Green Capital project had really engaged all of our citizens, from all perspectives and all walks of life. The answer to that was complex and we will be exploring that more during 2016 as the conversation continues.  But there was an overall consensus that much had been achieved but much more could have been achieved.  It seems a common opinion as 2015 races towards its conclusion in Paris.

I’ve seen this tension between satisfaction and ambition exemplified on a large scale by Andrew Garrad, co-founder of Garrad Hassan now part of DNV-GL, Chair of the Bristol 2015 Company and member of the Cabot Institute’s Advisory Board. He has spent 35 years in the wind industry; in one sentence he can celebrate the success of UK renewables, which in 20 years have become central to the UK’s energy mix, and then pivot to regret that he has not been able to push even further.

This is something that sometimes frustrates me about my adopted city but that ultimately I love – and is perhaps what I love most about it. No matter how much we achieve, we argue about how we could have done better.  Or more.  Or faster.

Bristol is the least complacent place I have ever lived, sometimes exhausting but always exhilarating.

I am concluding this first blog on Sunday night, having just returned from the Climate March, which drew thousands of people on a cold, wet and windy day.  And at which people sang songs, chanted, cheered – but also debated and argued and demanded more innovation and more action.  My abiding memory of the Climate March will be listening to the smart, informed and passionate debates among members of the Bristol Youth Council about the future of their party. 

That edginess and ambition is exactly what the whole planet needs as we tackle the profound challenges not just of climate change but the sustainable use of the resources on which we depend. No matter what happens in Paris, complacency must not be accepted and it will not be accepted in Bristol.

Bristol was awarded the European Green Capital in part because we are ‘the City with a sense of fun’.  And Bristol is fun – and quirky and odd and artistic and brilliant. But it is also edgy and passionate and often proudly unsatisfied. We do not have all of the solutions, but we will never stop looking. That is the Bristol I will be taking with me to Paris.

Delivering the ‘Future City’: our economy and the nature of ‘growth’

In Bristol’s European Green Capital year, the University of Bristol and its Cabot Institute have been working with the Bristol Green Capital Partnership and its members to convene a series of four conversations between Bristol academics and city ‘thinkers’ from across public, private and civil society exploring how Bristol delivers the ‘future city’ –  what capacities it needs to be resilient, sustainable and successful and how it can start to develop these in times of changing governance and tightened finances. The conversations will be reflected in a series of four blogs (the fourth below) and then brought together as a policy report as well as discussing at the Festival of the Future City in November.  You can connect to the other blogs from this series at the bottom of this blog.
—————————————-

Wordle of what we thought we’d talk about…

Cities such as Bristol are increasingly prominent in national growth strategies. The economic growth that Bristol helps to drive plays a fundamental role in shaping many aspects of life within the city. Different sectors, areas and social groups participate in and feel the impacts of growth in different ways. For some, the need for growth is unquestionable, particularly in an era of austerity, with the assumption that growth somehow underpins the pursuit of all other objectives. But for others, the pre-eminent growth logic is divisive socially and unsustainable environmentally. Growth therefore needs to be at least managed and possibly challenged more fundamentally. In this fourth conversation we considered what economic models make sense for the city and what capacity the city has to make changes in the context of a national and international economic system.

Growth – the elephant in the room?

In considering the future economy of the city, growth is the dominant idea but does this have to be economic growth with the associated ongoing increase of resource consumption? As we saw when discussing austerity, GDP growth is not contributing to long term stability environmentally or societally.   This debate was an opportunity to further explore growth and other measures of prosperity and how much is within the city’s control.

One participant drew an analogy with the natural environment and the way that living organisms are born, develop, mature and die – there isn’t enough space for everything to grow indefinitely. If we only talk about growth then we are only talking about half of life and missing the bit where some things die in order to make space to develop and nurture other life or something new.

There are two big reasons for needing growth, one is to service (interest bearing) debt – to pay back more than was borrowed needs growth. The second reason that growth is the mantra, particularly internationally, is that if a population is growing, you need economic growth otherwise by definition living standards are declining – and population growth is something else that is difficult to talk about. There is a common perception of growth as meaning success, an investment for your children.
What are the alternatives and how to we get to something that is more about leading happier, more fulfilled, healthier lives, something about development rather than growth?

International vs. local

One of the problems is that we are part of a global system, but there are things that a city controls and can change. The more business that is done locally or regionally, the more that power and funds move away from big corporations to something more transparent and locally based, where the organisations have a direct interest in the populations that they serve.

If the current systems seem too embedded and talk of developing alternative frames and narratives too difficult to achieve then don’t talk, just do things differently. The idea of ‘everyday making’ is that individuals just start behaving differently day-to-day, it has a cumulative effect and the end product is change. It’s an idea in academic literatures but it can be seen in real life too. Examples include buying food from local suppliers, ethically sourced clothing, and saving in green investment funds. In Bristol, the Bristol Pound is a manifestation of this idea – that by having a local currency people can gradually make more conscious consumption decisions. The new ‘Real Economy’ network has been developed through the Bristol Pound in an attempt to challenge the dominance of big business supermarkets. In the Real Economy, buying groups source food from local producers to start to create a food system that is fairer to all.

Talking about economics

Another issue is that many people feel disempowered when there is talk of economics, they feel that they don’t know enough, that somehow only the experts understand and can manage the system. It’s not really a conversation for the pub or at the school gates and that plays into the hands of the vested interests. The dominant free market right have captured the narrative with the idea that only growth can support ‘hard working families’.
There is such a dominance of growth as being the necessary outcome that it’s easy to portray everyone outside as excluded or naïve. In this narrative, growth translates as success and anything else is irresponsible.

Is it really a free market?

Could a true free market take account of climate change and value natural capital and social capital? These issues are not even really in the (mainstream) discussion yet whilst government subsidies support some industries and don’t let them die or change when they should. For example, banking; or the petroleum industry, which perhaps should be dying because of its costs – even before taking into account the environmental cost. Subsidies skew these markets.

There’s also a simplistic perception that everybody who is in the private sector (or at least the big business, multi-national part of it) must be bad but there are many entrepreneurs who act ethically and responsibly, who want to create good (local) businesses that employ people on fair wages and give back to their communities.

Part of the problem is that we’re all part of a very complex, interdependent system. This interdependency allows risk to be shared. For example if a city loses core industries, employment and income, shared resources from central government are there to help out. These interdependencies are highly complex which is why cities and businesses are not allowed to fail – for now at least, we’re all tied together in a global monetary system.

Politics, power and change

Our current political system draws some of its power from big business, paying taxes and providing employment, but also with the power to lobby to maintain the status quo. The powers in the system not only prevent things from dying but prevent change too and, although of course we need employment and tax receipts, there needs to be a mechanism whereby changes can happen more quickly. At a personal level, change is uncomfortable, so people vote for what is familiar, even if they don’t really like it, because it feels safer. It was suggested that the neo-liberal movement has succeeded in making all of us resistant to change. It’s scary, change takes us into the unknown and that feels risky, especially when we’re feeling vulnerable.

The constant growth narrative feels to some like a form of oppression. Individuals feel disempowered and that no-one else feels like they do, that they are all alone in being the good guy, all alone in arguing against the current system and narrative. There are many groups and conversations reflecting this view but they are fragmented and weak against the established power structures. Can a city bring its dissenting voices together into a more powerful collective? What is within its power to change?

…Wordle of what we talked about during the debate.

New approaches

This conversation started feeling a bit gloomy, that all the wrong people have the power, that we’re all alone in trying to make changes, that anyway we’re a bit powerless in such a globalised system and that the two big reasons for needing growth seemed unarguable.

A few good examples from around the world got us thinking about what could be done at the scale of Bristol. The examples from elsewhere included Ecuador which has legislation for the rights for nature, Sweden is experimenting with six-hour working days and Bhutan has a measure for gross national happiness. What could be the different ways of measuring economic welfare in the city – and which are not trying to put a monetary value on non-monetary issues such as quality of life or care for the natural environment?

The shift from growth to development or other forms of prosperity could involve a major change in how we see the economy and what we want from it. Rather than seeing growth as the end in itself, the economy should be seen as a means to achieve different development goals such as better public services, improved housing, increased inclusion, reduced inequality and greater levels of sustainability.  This would take a cultural and structural shift – overcoming the vested interests in maintaining the status quo.

What about Bristol?

There are already many parts of Bristol that are taking on big business and creating their own alternative economies with flourishing local enterprises and community-led prosperity coming out of them. The people of Bedminster are fighting against supermarkets and pawn shops, Knowle West are looking at pop up manufacturing and 3D printing, Lawrence Weston and Southmead have great momentum and visions for the future. Neighbourhood partnerships are working really well in some of the areas that need them most, and there are great social enterprises in many areas. BUT, there is still the dark side and, unlike some parts of the North, people across the city don’t feel like they’re all in it together, more like ‘us and them’. As we have observed before in these debates, there is significant racial tension and inequality in the city, high levels of child poverty and differences in life expectancy of 10 years between different areas – and, even more shocking, a 20 year difference in healthy years lived.

With these problems in the city it feels really important that we make efforts to work together better, to learn from the good examples and to join up this conversation outside the university and across the city. The big organisations in the city, such as the health sector, universities, council and businesses, have an important civic role in contributing to the wellbeing of the city. They have the resources and potential in their workforces, customers and supply chains to create new partnerships and city-wide change.

A new economic future?

When we talk about the allocation of limited resources there is no shared theory of value and no broader plan against which to share resources. So, for example in the health service, the budgets are boundaried and it’s easier to measure success of spending on cardiac surgery than it is to allocate resources to preventing heart disease with less predictable results somewhere in the future (that short-termism again). People across organisations collaborate in multi-agency partnerships but much of the actual resource allocation comes back to core service delivery. We need to understand where the power lies that can unlock these behaviours and allow longer term decisions to be made.

Again in this debate we talked about reducing inequality and creating a fairer system. The aim of the Bristol Pound was to support a green and fair economy – more equality and a more sustainable way of using resources. There is a wider role for business in contributing to life in the city, to have a positive impact. Local businesses and social enterprises are more connected with their communities and larger organisations have a civic role.

In the future we need to think more about what the economy is for – how to help pay for public services and improve housing, increased inclusion and greater levels of sustainability. We need to understand how to measure the real cost of environmental damage and that growth in itself is not the aim.

And sometimes we just need to do it, to make changes locally, to work together and to act on our beliefs in a way that supports the new economic system that we want to see.

Uncertain World: Reflections

This last week we have been focussing on our Uncertain World, with a host of events and interactions to meet with new communities, think around new ideas and establish new solutions for what’s in store for us in the future.  You can read the other blogs covered in ‘Our Uncertain World’ at the bottom of this blog. Join the conversation with us on Twitter using the hashtag #UncertainWorld and contribute your thoughts and concerns to our (virtual) graffiti wall.

——————————————————————–
Over the past year, the Cabot Institute have been exploring this Uncertain World. I have been lucky enough to have attended, and written about, two events that have occurred this week – a public dialogue event and a Question Time event. This last blog is a way for me to reflect on the event and my thoughts on moving forward in a time of uncertainty.
At the events, I was particularly struck by how differently we perceive this uncertainty: both in our lived experience and our understandings of climate change. From concerns surrounding health to the criticism of how climate change is taught at school – every person I encountered or listened to saw something different and added new concerns. Particularly notable was the wide divergence in understandings of climate change, resilience and uncertainty between two of the generations present at these events. It is these perceptions that have guided my thoughts.
Out of fear of insulting you readers – I will refrain from labelling these generational conclusions in terms of ‘elderly’ and  ‘young’, or ‘mature’ and ‘naïve’. Instead, I will simplify them slightly – naming them after two people in my life: Maggie (my Nan); and Mary (my goddaughter). Maggie is 77 and enjoying retirement; Mary is four months old and doing a good job at avoiding colic.

Maggie

Many lack concern for climate change because they feel that they will remain unaffected. There is a greater concern in episodes of more-traditional conflict. Aside from Atlantis, there is no historical reference for the fate of Tuvalu in a world of rising sea levels. We fear armed conflict because of popular memory but how can we conceptualise climate change when we have no reference point to refer to?
Generation Maggie remembers the Second World War and much of their understandings were guided by their memories of the uncertainty generated by the conflict and the communal responses to this danger. This provides an important window into understanding uncertainty – the traditional perception of an existential threat, and how climate change often exists outside of this framing.

communal responses to this danger. Image credit: Wikipedia.
With age often painted as a contributory factor in scepticism towards climate change, it is important to understand that this may not be borne out of a lack of belief. Instead, it is driven by the conflict between the uncertain nature of climate change and the tangible, real threat that traditional conflict has posed in the past.
This problem is very different from the Blitzkrieg that transformed our cities into rubble during World War II; and, rather than labelling these sceptics “idiots” (George Ferguson’s words, not mine), we need to seek to engage with those who perceive climate change as uncertain and empower them to understand its role as a greater risk than we have ever experienced. World War Two may be a scar on this nation, but climactic shocks provide a threat that will be even harder to resist.
This experience also points to an important case of pooling of risk. Risks and resources were shared, community spirit was emphasised and everybody played their part. Food insecurity created rationing which, in turn, led to personal innovation and better diets than today. This may be rose tinted glasses but, as discussions uncovered, it is this form of community engagement, support and joint-adaptation that might provide the most effective routes to tacking climate-induced uncertainty in the future. Some still hark back for a return to these times; perhaps we should also look back and look to this community-resilience for inspiration.

As Bristol Youth Mayor, Neha Mehta said at the Question Time panel, young people care. They have enthusiasm and empathy and, importantly, the desire for change. At the Question Time event, I found myself lucky enough to be sat behind Bristol’s Youth Council. For the hour and a half, their heads did not drop. In fact, it was one of their numbers that asked the most challenging, and perhaps most pressing question of the evening: just how compatible are meaningful steps towards climate mitigation and a capitalist system based in corporate profit? A question that many have tried to find the answer to and I will not dare not elaborate on.

Time event in October 2015.
This generation will suffer from a greater degree of uncertainty in employment, finance and fulfilment of fundamental needs than the generation that has come before. Significantly, this increased instability will occur at a time when climate change will become more evident and the need for adaptation more extreme. This is not a cry of defeat, perhaps this increased uncertainty in all parts of life shall result in an increased innovation, creativity and passion in meeting these challenges and fulfilling the necessary transformations. Evidence of this can be found in the fossil fuel divestment movements that are sweeping across the education institutions of the globe.
According to even medium projections, future generations will inherit a very different world to the one that you and I inhabit. This raises an important need to expand these discussions to younger generations. The solution to these problems cannot just come from the leaders of today, but also the stewards of tomorrow. The young must be inspired to see that change and strive for it.  For Neha, the answer must lie in education. Climate change can no longer be simplified and taught as just one aspect of a wider syllabus. Lessons must seek to inspire and advocate the individual and social change necessary to combat climate change. It is only through this engagement that today’s young people can become the future leaders that the climate change regime really needs. 
At the Question Time event, Leo Hickman posed a thought-experiment: 

“Has one generation ever done anything selflessly for the next?” 

But, why must the need to act lie in one generation? Successful mitigation and adaptation cannot only involve the empowerment of the young. There is no monopoly on change. It must occur at every level and embrace every member of the community – empowering them to make the behavioural changes that are necessary for resilience. 
The framing of climate change as an issue of the selflessness of one (future) generation transfers the need to act from one generation to the next, whilst neglecting the role that the past may play in the present. The climate change regime cannot only look forward; it must also look back to older and previous generations for inspiration. It is not a question of one generation sacrificing all for the future – it is a necessity for generations to work together to ensure the future is empowered and a better world is left.  

 

This must not be selfless sacrifice by a saviour generation, this needs to be a communal pooling to ensure resilience – and the precedents for this are there.

The current rate of environmental change is unprecedented in Earth’s history and many aspects of climate change are understood. Yet, others are not. Scientists can say with a high confidence that temperatures and sea level rise – but continue to remain uncertain on the scale and speed of such processes. Policy makers are now challenged to make decisions that possess long term repercussions on the basis of information that is deemed uncertain. However, it is not just the science that may appear incomplete – social, economic and regulatory trends also remain unpredictable.

It is this relationship between policy and an uncertain environment that was the focus of the Cabot Institute’s Uncertain World: Question Time event on the 21 October 2015. Chaired by Andrew Kelly of the Festival of Ideas, the panel included: Bristol Mayor George Ferguson; Bristol Youth Mayor Neha Mehta; Leo Hickman of the Carbon Brief; Peter Macfadyen, formerly Mayor of Frome and a leader in the Transition Town movement; and Ann Cousins, a Sustainability Consultant at Arup
This Question Time event forms part of a wider ongoing dialogue between the Cabot Institute and the Bristol public,  based on making climate-based uncertainty real, relevant and personal for all – whilst exploring what climate change means for this city and its inhabitants.
As George Ferguson said in his opening statement, 

“the stars do seem aligned for Bristol”.  

This is true – the city is European Green Capital, one of the Rockefeller 100 Resilient Cities, and possesses a vibrant sense of community that previous conversations have drawn upon. Recent surveys have shown that over two thirds of the city’s population are concerned with the effects of climate change – as a local and a global issue. This provides a clear mandate for this city, and its leaders to act. 
Yet, as Ann Cousins and Leo Hickman argued – it is not just the traditional decision makers who must make these changes. The inspiration of figureheads cannot occur in a vacuum. We are all leaders – be it via changing our own behaviour or by engaging with others to change theirs. 
What became particularly evident in discussions at the public dialogue event was the focus on the local community to meet uncertainty. It is this pooling of risk that resulted in some of our most innovative, and important, social institutions – with the NHS providing just one example. In the face of increased social uncertainty today, many have independently set up food banks and swap-shops – resulting in cooperative ventures and the circular economy becoming more commonplace. It is no secret that the effects of climate change will be first felt at the local level – and it is this pooling of risk that provides an important route to adaptation.
As Frome has shown – and Peter Macfadyen voiced – the answer lies at the community level. For meaningful change, policy must move beyond mere nudge theory and towards tipping points. Change can only occur by giving people agency – by inspiring them to embrace individual mitigation and adaptation strategies. From decreased wastage to selling the car and waiting at the bus stop. This cannot occur in isolation – it must embrace the complexity of climate change as a social issue and link it directly to the lives we live. Radical change will be necessary but it will be a quiet revolution, based on information and engagement.
 
Peter Mcfadyen (centre) tells the room that the answer to climate change lies
at the community level.
Although there may be wide agreement that climate change is occurring – there is often a popular disconnect between the phenomena and its consequences for us as societies and individuals. When the media talk about climate change scepticism, they are usually referring to people who are uncertain about the reality or seriousness of climate change. Psychologists at the University of Illinois have found an important discrepancy between how the term ‘uncertainty’ is meant in scientific reports and how it is interpreted by others [1]. This is a problem when the 2013 report of the Intergovernmental Panel for Climate Change used the term over 2200 times – approximately 1.5 times per page of the report of the working group alone [2].
A number of the event’s questions focused on the need for radical change in Bristol – including the pedestrianisation of the M32, Oslo’s ban on cars, and a policies on inter-community recycling and reuse. This struck me – the desire for radical change was near-unanimous. But, how representative of this is Bristol as a whole? Many still posses a tunnelled vision and a drawbridge mentality in their understanding of shifting climates – “it’s not affecting me, why should I care?” Priorities lie elsewhere: securing basic needs, prosperity, health, etc. Sadly, climate change doesn’t possess the minds of many.
Seoul – pedestrianised one of its motorways. Is this on the cards for Bristol’s M32?

Climate change continues to feel distant. A question for science, rather than society. We have seen the images of Hurricane Sandy and of sea level rise – but these are from a different world, a great distance from our front doors. The biggest question of the night for me will continue to plague me for a while longer: Has Bristol felt climate change enough to cause this behavioural change on an individual level? And, if not what will it take?

The end of the road for diesel?

Smoggy day in Bristol
The Volkswagen (VW) emissions scandal is now into its second week, and with each day the enormity of the deception seems to increase. What started off as a few hundred thousand cars in the US has now become an astonishing 11 million cars worldwide that VW says may have to be recalled. In addition to the VW brand, diesel models of Audi, Skoda and SEAT cars have all been affected, with 1.2 million in the UK alone.
 
At the heart of this deception is the use of software, designed to be able to detect when a car was under test conditions, in order to reduce the emissions of a group of nitrogen and oxygen compounds, commonly referred to as NOx.  However, these emissions controls would not be switched on during normal driving.
 
Given that the cars were clearly built with the potential to emit less NOx, it’s not immediately clear why the emissions controls were applied only under test conditions.  Although VW have admitted they “screwed up”, they don’t seem to have said why. However, it’s a fair assumption that the emissions controls would affect the performance of the car, both in terms of drive and fuel economy. Since fuel economy is probably the main selling point of a diesel car, anything detrimentally affecting it, could easily lead to a decline in sales.
 
In addition to the flouting of the rules by VW, the wider issue is the NOx emissions themselves, which are a seemingly inevitable product of diesel powered vehicles.
 
The use of diesel as a fuel in cars has been on the up (in Europe at least) over the last couple of decades, with a supposedly superior fuel economy and hence lower CO2 emissions, meaning they have been incentivised in Britain with lower tax. However, this policy failed to take into account other pollutant emissions such as NOx and particulate matter that have been linked with thousands of premature deaths. Indeed, this push to diesel was labelled in a Channel 4 documentary earlier this year “the great car con” and just this week former science minister Lord Drayson called this policy a mistake.
 
Due in part to this push for more diesel vehicles on the roads in the UK and Europe, Bristol is just one of many cities which fail to meet the 40 μg/m3 annual mean WHO guideline level for NO2 (one of the collection of NOx gases). NOx levels in the UK have seen only a very small decline over the last decade or so, despite vehicle manufacturers telling us they make the cleanest cars yet. This contrasts with petrol vehicles, which have seen a dramatic decrease in NOx emissions over this time.
 

Why is NOx bad?

 
The presence of NOx in the lowermost part of our atmosphere, along with other pollutants such as volatile organic compounds (VOCs) promotes the formation of ozone. Not to be confused with the protective ozone layer which is much higher up in the atmosphere, ozone near the surface has detrimental health effects, mostly involving the respiratory system, in addition to being a greenhouse gas. Furthermore, NO2 has itself been linked with certain respiratory health problems
 

Is there a simple solution?

 
Well, technologies exist to reduce NOx emissions from diesel vehicles, such as urea injection, only it seems that the VW group chose to cheat the system rather than use it, since it would add cost and weight to the car. If these technologies are implemented manufacturers claim to be able to filter out particulate emissions and greatly reduce NOx emissions. But, given the current furore, why on earth should we believe them?
 
In addition, a recent report from the International Council of Clean Transportation (ICCT) said that the real-world CO2 emissions of diesel (and petrol) cars are well above those in tests. There go the supposed CO2 savings of diesel then. Again you can’t help but question why diesel cars continue to enjoy a tax break in this country.
 

The death knell tolls for diesel…

 
…Ok, maybe not. Given the massive investment that the automobile industry has put into diesel over the last 20 years or so, they’re unlikely to suddenly jack it all in. What will probably follow is a splurge of marketing diarrhoea about how each new car is the ‘greenest yet’, all the while completely ignoring the fact that the simplest way to cut emissions would be to have fewer cars not more. Nevertheless, the current news story highlights how frivolously pollutant regulations, and the health implications, are taken when set against generating a profit. It also serves to impress the need for independent verification of emissions, such as those that uncovered VW’s fraudulent behaviour. The Atmospheric Chemistry Research Group here at Bristol, performs similar verification at the national level for greenhouse gases. It has been said that not taking the time to verify emissions statistics is like dieting without weighing oneself. Well, in this case I guess they did make it to the scales, but no one bothered to check they’d been calibrated properly.
