Expectations of receding, thawing and melting of the Arctic have prematurely driven investments and geopolitical negotiation over Arctic marine territories and resources. The elusive mathematics of ice dynamics hamper robust forecasting and modeling, and the incongruent scales at which it is defined pose challenges for planning and coordination. Together, these form a high-risk context for Arctic industries and nations that seek to follow the ice edge northward.

Mapping sea ice
Sea ice behaves unlike other major earth surface processes. Neither purely fluid nor solid, ice does not conform to classical Newtonian physics. Fluids like water and air respond to stress continuously and evenly down to the molecular level. Solids respond to stress by deforming elastically or plastically, or by shattering. Sea ice shares characteristics with each. To represent ice in mathematical models, therefore, physicists have developed ‘parametrisations’ by combining different Newtonian behaviors. These include a ‘cavitating’ fluid and a ’viscous–plastic’ or ’viscous–plastic– elastic’ solid. These Newtonian approximations, called ‘rheologies’, seek a compromise between computational efficiency and realistic stress responses. Dynamical rheologies are incorporated in models that also include the thermodynamical response of ice to sunlight and heat. The model developer judges the level of detail to include – the impacts of brine pockets, algal growth, soot, and ice nucleation, for example. Finally, the ice model is connected to models of ocean and atmosphere. Balance is sought between accuracy and spatial detail on the one hand, and available computing power on the other.

Using statistical models avoids these challenges by only considering sea ice area and movement, but comes with its own compromises. Here, modelers measure sea ice area and movement over a period of time using buoys, ship and aircraft observations, and satellite measurement, and predict future sea ice behavior based on its past behavior. Forecasts over two to three weeks based on this approach are usually acceptable; the challenge, though, is that predictions are only as reliable as the available data. Furthermore, this approach cannot anticipate sea ice distributions that have not previously been observed, such as a lower global sea ice extent. This is an important issue given the influence of climate change. As a result, the seasonal and decadal projections that industry needs for planning investments in Arctic activities have high uncertainty.

Governing sea ice
Arctic nations have developed different frameworks for governing seasonally ice-covered waters, and the United Nations Convention on the Law of the Seas is in the process of clarifying its framework to assist nations in staking claims to Arctic territory. In United States policy, Arctic industrial activities fall under Federal, State or Borough jurisdictions, depending where the ice edge lies any given time. Drilling and shipping in the United States Arctic therefore follows the freeze and thaw of the ice edge over its c. 1500km range.

In Norway, a political push to protect the ecosystems in the marginal ice zone led to the ice edge becoming a fixed line to regulate industry. As result, the ’15 percent’ ice edge definition of ice modelers has come to define the safe limit for oil and gas exploration. Until 2014, statistical models were based on observational data from 1967 to 1985, but in 2014 the more recently recorded dataset of the National Sea and Ice Data Center in the United States for 1985-2014 was adopted. Because of the polar amplification of climate change, this defined ice edge was further north than earlier decades, opening further oil fields for exploration, and opening pointed debates about the use of science for political interests.

Yet in the hustle of activity to define an unrealisable fixed boundary, the sea ice itself intervenes, along with global oil markets and geopolitical uncertainties, to create a high-risk environment for investments. The Kullug accident in the Chukchi Sea points to overconfidence, Barents Sea drilling has so far disappointed, and Shell has pulled out of the Arctic.

Ice edge narratives
Discourse on the ’melting’, ’receding’, and ’thawing’ Arctic has dominated climate change narratives over the past decades. ’Vulnerable’ Arctic Indigenous nations feature as poster children of efforts to reduce greenhouse gas emissions and fund adaptation measures. With recent record-low sea ice extents, these perceptions have led to an assumption that the Arctic will soon be open enough to host petroleum installations and to compete with the Suez and Panama Canals as a sea route. National governance of Arctic sea ice sits at the intersection of highly dynamic and insufficiently understood earth system processes, old and new cultural values, and numerous valuable industrial activities. In this complexity, a cognitive simplification of processes may have overestimated the potential of this region as a new industrial powerhouse.

Our paper in Area approaches these insights by proposing narrative as a framework for analyzing multiple and complex representations of earth processes. The paper highlights the many discourses and scales across which the ice edge is defined and governed, and the challenge of reaching convergence in policy. We urge that industries and governments that would invest in petroleum, shipping, or other activities near the seasonal ice edge avoid relying on simplified narratives of receding Arctic ice. Risk is lowered if openings exist for deliberative processes that incorporate a variety of story-lines about what the Arctic is, and what activities are permissible.

More Than Pedestrian: The Magic of Walking

Public Health England has launched a new campaign “Active 10” to encourage adults to go for a brisk walk for just 10 minutes a day to help improve health and well being. Living Streets have been campaigning for walking cities and encouraging safe walks to school, and Chris Boardman has recently been appointed to become Greater Manchester’s first ever cycling and walking commissioner.

Walking is good for you and the environment. It can also be fun but “pedestrian” has a double meaning, and can be seen to be a bit, well, dull. In a recent article for Transactions, Alastair Bonnett shows us walking can also be magical. He follows an “enchanted path” to explore the work of psycheographers. Psychogeographers use walking to explore and critically engage with the urban landscape; psychogeography provides opportunities for “an uncovering of the city’s possibilities and a desire to listen to its occulded knowledge” (Bonnett 2017: 478).

A psychogeographer does not take the simple route from A to B. They wander, drift and derive. They may use playful techniques to choose the direction of their walk, for example throwing dice or following a line drawn on a map. Their journey began with the radical avant-garde of twentieth century Europe; The Situationist, Surrealists and Lettrists. Bonnett describes their walking as going “against the grain, avoiding and confronting routines and creating new patterns and situations” (2017:474). Psychogeographers concentrate on where they are walking to uncover hidden voices, and power structures that shape modern cities.

Bonnett paints a picture of psychogeographers casting spells and changing the landscape as they walk. He concentrates on three different writers who employ magic in different ways to remap and rewrite London. Nick Papadimitriou has a close, personal, mystical relationship with the Scarp in North West London. John Rogers often uses humour to uncover his alternative city whilst the work of Gareth Rees conjures poetic phantasmagoria from wasteland and evokes the ghostly in the everyday. His dreamwork is an activism, magic with a political intent.

The writers Bonnett focuses on are all doing fascinating and excellent work. However it is also worth noting that contemporary British psychogeography is more diverse than a focus on three men walking in London might suggest. In her excellent overview Tina Richardson identifies what she calls an emerging “new psychogeography” which is, amongst other things, heterogeneous, critical, strategic, and somantic. It can be seen in the work of Jane Samuels, whose work illustrates this blog, Phil Smith a mythogeographer and counter-tourist, and many members of The Walking Artists Network. If you fancy finding out more The Fourth World Congress of Psychogeography convenes in Huddersfield this September for three days of talking and walking. You would also be very welcome to join me and The Loiterers Resistance Movement in
Manchester as we embark on a psychogeographical wander on the first Sunday of every month, celebrating creative mischief and search for magic in the Mancunian rain.

As Bonnett shows us, Psychogeography is a practice that combines art, activism, academia, and more. Magical modernism takes many enchanting paths and I encourage you to explore them.

The fluid geographies of marine territorialisation processes

By Paula Satizábal, University of Melbourne, and Simon P J Batterbury, Lancaster University.

Empty-yet-full imaginaries

Oceans are framed by policy makers and governments as being empty of people and full of resources available for capital accumulation (Bridge 2001). They are portrayed as containers of open access public goods (e.g. the Exclusive Economic Zones prescribed by the United Nations Convention on the Law of the Sea). These images are used to facilitate the privatisation of fishing grounds and other productive areas, as well as to justify the overexploitation of marine resources, which are generally under very limited state control. People who live near coasts are often excluded from conversations about how marine territory is negotiated.

People living at the intersection of land and sea have not been passive observers of these processes of accumulation by dispossession. Despite an absence of institutional instruments that recognise peoples’ marine territorial rights, several groups and communities have relied on marine conservation enclosures as the only legal tool available to legitimise their authority over the sea. However, for many, this is not a long-term solution; once a marine protected area has been established coastal peoples are often excluded from decision-making arenas.

Previous research has highlighted the key role played by state and non-state actors in negotiating land-based territorialisation. However, the role played by socio-cultural dynamics on guiding and informing marine territorialisation processes has been largely overlooked. Our recent publication in Transactions of the Institute of British Geographers, entitled ‘Fluid geographies: marine territorialisation and the scaling up of local aquatic epistemologies on the Pacific Coast of Colombia’ (Satizábal & Batterbury 2017), addresses this gap. We examine the participatory process undertaken by coastal Afro-descendant communities along the Gulf of Tribugá on the northern Pacific coast of Colombia, which enabled them to take part in the state production of territory at sea through the creation of a marine protected area.

Local aquatic epistemologies

Ulrich Oslender (2016) coined the concept of ‘local aquatic epistemologies’ to denote the ways of knowing that result from the entanglements of humans in aquatic environments. We argue that coastal dwellers in the Gulf of Tribugá hold ‘local aquatic epistemologies’, which is where knowledge has been produced through the individual and collective experiences of people entangled in the fluid dynamics of rain, rivers, and sea, as well as through their interactions with indigenous and expert knowledge.

Coastal people along the Gulf generally conceived the sea as a lived space, where territory is constructed through everyday practices, moving beyond marine/riverine/coastal divides. However, the collective territorial rights granted to Afro-descendant communities in Colombia since 1993 only recognised their rights over the land, reproducing the spatial logics of the colonial period. Conflicts between coastal communities and the deep-water shrimp and tuna industrial fisheries have escalated since the 1990s due to the impacts of overfishing and excessive bycatch. These conflicts cannot be reduced to threats to coastal food security or access to fishing resources; they are an important part of coastal dwellers’ efforts to defend their marine social spaces and authority over the sea.

The marine protected area

With the support from conservation NGOs, and informed by their local aquatic epistemologies, these communities are navigating the state institutional apparatus. They have used formal institutional mechanisms to claim their marine rights through the creation of a marine protected area. The process has been centred on the conservation of fishing resources, relegating the socio-cultural dimensions of their marine claims to the background.

The creation of the marine protected area on the Gulf of Tribugá involved the scaling up of local aquatic epistemologies. This has enabled Afro-descendant territorial struggles to reach national negotiation arenas, transforming relations of authority at sea. The marine protected area emerges as a space of resistance that subverts the lack of legal mechanisms to assert the marine territorial rights of coastal people. These spaces are, however, still dominated by the interests of the fishing industry.

Although this process contests marine empty-yet-full imaginaries, the creation of marine protected areas remains centred on access and control over fishing resources. We emphasise the importance of developing legal instruments that overcome marine coastal divides and recognise the relevance of marine social spaces as part of indigenous and afro-descendant peoples’ territorial rights.

Does green infrastructure represent a sound investment opportunity?

By Steve Cinderby, University of York, UK, and Sue Bagwell, London Metropolitan University, UK. 

Globally our societies are becoming increasingly urbanised with the United Nations (UN) reporting that already the majority of people live in urban settings with predictions this will rise to 66 per cent by 2050. Historically this has often meant increasingly constructed, grey, environments, however, there are increasing demands to green our cities with the introduction of more plants and trees.

Last month London’s Mayor, Sadiq Khan, unveiled plans to make the English capital the world’s first “National Park City” by 2019. With initial funding of £9M the intention is to increase the amount of green space including encouraging the development of more green roofs, green walls and rain gardens. This initiative connects to the UN Sustainable Development goals for cities and the calls for accessible greenspace made in the New Urban Agenda that emerged after the 2016 UN Summit on Future Cities.

Whilst some have highlighted the challenges for an existing cityscape like London of introducing more green into the urban fabric alongside demands for housing, businesses and service infrastructure recently published research indicates that the Mayor’s plan could bring not just environmental benefits (reducing surface water flooding, improving air quality, cooling urban heat islands and increasing local wildlife diversity) but also improve the mental health and well-being of Londoner’s and increase the economic vitality of the city.

Our newly published Area paper describes the impact of introducing a relatively small number of green infrastructure schemes around Victoria station in London. The findings illustrate that as well as the known environmental returns investing in urban green infrastructure within existing neighbourhoods could also make sound financial sense. The research provides new evidence that city greenery can increase customer footfall particularly for retail and leisure businesses, encouraging visitors to ‘linger-longer’ and potentially ‘spend more’ in a pleasanter environment. In our city workplaces the study found that investing in office greenspace improved staff member’s morale and work satisfaction. Greener workplace setting also seem to encourage staff to adopt more sustainable behaviours including better energy saving and recycling again potentially bringing both environmental and economic benefits.

This new evidence indicates that, alongside the London Mayoral investment, the city’s private enterprises should also consider financing the incorporation of more green infrastructure into new building schemes whilst retrofitting green walls and street trees into existing neighbourhoods where possible. These improvements could boost their economic value for retail and desirability for employers. A National Park City investments could not only make environmental sense but could bring sound financial and well-being benefits as well.

“Ethical Oil”: Does geography matter?

By Jillian Smith, University of Birmingham


Photo Credit: Peter Essick

The phrase “ethical oil” went mainstream in Canada in 2010 after a national bestseller of the same name.  The book, written by Ezra Levant, a right-wing political activist and lawyer, gave this simplified primer: Canada is a friendly, secure petro state; Saudi Arabia and OPEC (Organization of Petroleum Exporting Countries) are conflicted and undemocratic.  In other words, the opinion is that Greenhouse Gas (GHG) emissions and climate change aside, Canada’s oil is “ethical”.  Opinions aside, the International Energy Agency – a Parisian-based intergovernmental organization – states that depending on the region, Canadian oil is 5-10 per cent more GHG intensive than U.S. conventional fuel from extraction to combustion (well-to-wheel) (IEA, 2011).  Bradshaw (2010) recognises that globalisation, climate change, and energy security are intricately linked; he strives to explain why geography complicates the interaction of climate change and energy security. Bradshaw dubs this the ‘global dilemma’.  While the momentum of Levant and his ‘ethical oil’ campaign may have become distant memories, given the scope of climate change and energy security, it is worth reflecting on why it was paradoxical to rebrand Canadian oil, or any oil, as “ethical” in the first place.

Oil sands development constitutes Canada’s fastest growing source of CO2 because of the large amount of energy required to extract bitumen from sand.  Additionally, after accounting for the natural gas that powers the process of converting bitumen to crude and the removal of Boreal forest (a large carbon storehouse), Canadian tar sands oil can emit up to three times more GHG’s than conventional oil (Hatch and Price, 2008).  Despite plans to reduce emissions per barrel, with development scheduled to proceed, overall emissions will inevitably rise and the global issue of climate change could weigh heavily on Canada’s shoulders.

In March of 2017, President Trump gave an enthusiastic green light to the “incredible” Keystone pipeline.  This 1400 kilometre mile pipeline will transport up to 830,000 barrels of Canadian crude to Texas.  The State department said it considered foreign policy and energy security in making the approval.  This aligns with Levant’s argument that the world has a choice: embrace Canada’s peaceful, democratic oil or continue its dependence on OPEC’s dictatorship, conflict oil.  Levant, however, went further to suggest that the question of morality must encompass human rights issues independent of environmental costs.  In his mind, reliance on oil from dictatorships to “save modestly on greenhouse gases” was a misguided notion.  Many Americans and Canadians, however, would beg to differ – environmental costs do matter.

Levant, however, is no stranger to controversy and libel.  A former tobacco lobbyist, he is adept at weaving intricate webs.  His favourite spin in the oil debate was lambasting Saudi oil. Certainly a healthy dose of skeptisim and a critical eye is healthy in any society, yet when skeptics are given the same airtime as legitimate researchers, facts become blurred.

With Canada’s oil being celebrated and extolled, while simultaneously being criticized and decried, it is not surprising that Canadians can be confused about the dizzying array of incongruous oil sands reports.  As such, decisions and reformations must first be based on sound scientific assessments of the facts.  Consequently, the Royal Society of Canada (RSC) – Canada’s most prominent group of scholars and scientists, experts in their fields whom are peer-elected to receive this highest academic accolade and fellowship – published a peer-reviewed, comprehensive, 437-page evidence-based study of the oil sands in late 2010.

The report, while not as blasphemous as environmentalists would have liked, is certainly proof that Canada’s oil needs more than a rebranding makeover to be considered “ethical”.  The report concludes that “carbon capture and storage (CCS) does not appear to be a feasible option” and that increasing GHG emissions will create a major challenge for Canada to meet international commitments for overall emission reductions (Gosselin et al., 2010).

Fossil fuels, though intrinsically unsustainable, are the crown jewel of Canada’s multi-billion dollar energy sector.  But virtuous, ethical societies must aim to ultimately reduce oil consumption and pave the way for cleaner, renewable energy developments around the globe.  Additionally, ethical societies must conscientiously manage the resources they are entrusted with and devise coherent energy policies.  To date, North America lags behind the rest of the world in terms of energy efficiency and innovation.  Canada, with its enhanced regulatory oversight, can choose to perform ethically by embracing intergenerational thinking of a world beyond mere decades of oil.  Could some of Canada’s oil proceeds help pave the way toward a more sustainable future?  Regardless, it seems the words “ethical” and “oil”, though a clever marketing pitch, are not to be metaphorically mixed in the long-term interests of the planet or its people.
