Romani people occupy a complex social position within Europe, due to the stigmatization and discrimination they have faced for centuries there. Numerous studies have shown a strong ‘Romaphobia’ in European contexts (van Baar, 2011), positioning the Roma as Europe’s dehumanized ‘outsiders’ (Powell and Lever, 2017). This literature highlights that ‘the trajectory of the Roma in Eastern Europe is towards ghettoization’ rather than towards integration thus limiting life opportunities in numerous ways for people living in those neighbourhoods, but also providing advantages like protection and solidarity (Wacquant, 2012). A significant amount of research and media news cover this marginalization and urban spatial segregation of Roma in Europe, but the experience of living in ‘Gypsy ghettos’ needs to be examined in a more structured way. Our recent publication in Area (Málovics et al. 2018) addresses this challenge by providing a bottom-up view of the complex phenomenon of place attachment among marginalized urban Roma in two ghettos in Szeged, Hungary.

Approximately 3% of the Hungarian population (300,000 Roma) reportedly live in segregated environments, of which at least 1,633 ethnicity-based segregated neighbourhoods are known (Domokos and Herczeg, 2010). Findings from Szeged activists’ six-year participatory action research (PAR) project demonstrate that characteristics of both place and community relations are key determinants of place attachment for segregated urban Roma. Social relations within marginalized Roma neighbourhoods are shaped by dual ties. Traditional relationships based on reciprocity still exist, representing not only significant material and emotional support for families but also strong expectations towards sharing and the lack of a private sphere. In addition, we observed a process of social and spatial disintegration: Roma communities are becoming more fragmented, members aid others only in times of great distress, and they exclude those on the margins. The physical characteristics of segregated Roma neighbourhoods exert a dual influence on place attachment: these are ‘beyond-the-pale’ areas for local and national authorities. Basic public services are thus often neglected, resulting in poor housing conditions and an untidy environment (Photo 1), but also the perceived benefits of cheap housing and the relatively unregulated use of open spaces.

The relationship of segregated Roma to their neighbourhoods is shaped by further factors that extend far beyond the neighbourhood. Being embedded in the surrounding area(s) might represent numerous advantages (including work opportunities). However, poverty, prejudices, discrimination and, stigmatization from mainstream society limit life opportunities in numerous ways, for example, the ability to use public spaces. Because of poverty and ethnic stigmatization, numerous Roma are unable to ‘appear in public (spaces) without shame’ (Sen 1999, p.71). The same applies to important social institutions, including even primary schools: Roma pupils either attend segregated schools or classes or are marginalized within integrated primary schools. Overall, place attachment among marginalized urban Roma is a contradictory phenomenon: it varies from one segregated neighbourhood to the other and is influenced by social relations, the physical characteristics of the neighbourhoods, and relations between neighbours and everyday processes within the wider society.

The desegregation of urban Roma ghettos has become an official goal of Hungarian local development policy but we found that numerous issues should be considered in this process. The most important issue is that Roma communities are marginalized and stigmatized at the micro-level of daily social relations. In order to understand marginalization we must look beyond merely policy-oriented approaches and consider wider (historical) social processes and power relations within society. The question for further research remains: how to effectively struggle against centuries of social and spatial exclusion and ‘political pragmatism’ (Marinaro, 2003) as regards the marginal position of Roma within European societies.

Birds eye view of climate variability

By Anusha Sanjeev Mehta and Robert Wilby, Loughborough University

The monsoons are the most important climate feature of India. They dictate the seasons and ultimately shape human well-being and livelihoods. But these dramatic transitions between hot/dry and cooler/wet conditions affect not just people but also the region’s flora and fauna.

Recently there has been a surge in nature-related recreational activities in India, particularly bird watching. Home to more than 1,000 species (of which about 45 are endemic), India is the ideal place for ornithologists. However, bird counts can vary a great deal between years, dropping markedly for example in 2015. Could there be a connection between climate conditions and birds in India?

Our new study, published in the journal Area, found that ocean-atmosphere patterns, such as the El Nino-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) in the Pacific and Indian Oceans, could be affecting the number of bird species and counts of selected bird types in the states of Goa and Tamil Nadu. This is because ENSO and IOD patterns are linked to regional precipitation and temperature anomalies over large parts of the world, including India.

We pooled bird data for the years 1990 to 2015 by prevailing ENSO and/or IOD phases. They discovered that greater numbers of bird species occurred under El Niño and/or negative IOD events compared with La Niña and/or positive IOD events. In particular, bird diversity is higher when both Goa and Tamil Nadu experience locally wet conditions (under El Niño) compared to locally dry conditions experienced during La Niña. It was also found that temperature has a strong effect on the number of birds. Overall, bird communities were more abundant under warmer/wetter conditions.

The Brahminy Kite, Indian Pond Heron, and Lesser Whistling Duck were used as marker species to further detect the influence of ENSO and IOD. All three species were much more abundant in Goa during El Niño than La Niña events, while more Kites were found in Tamil Nadu during negative IOD than positive IOD events. Some seasonal and lagged impacts on bird communities were also observed. The picture could be further complicated by ENSO and IOD events operating in tandem, but datasets are generally too short to be sure.

The changes in bird species and individual bird numbers may be due to the indirect effect of ENSO on prey, habitats, nests, and migration. Wetter conditions during the winter and pre-monsoon period are favorable for birds due to the increase in food and water availability and reduced negative impacts on eggs and young birds caused by high temperatures. However, very wet weather and flooding can destroy breeding grounds, negatively affecting bird communities.

The study contributes to scientific knowledge by showing how ENSO and IOD signatures may be detected in the bird communities of India. The approach could be extended to other indicator species. This could deepen our understanding of the future climate vulnerability of one of the most ecologically vibrant areas of the planet.

Exploring Cultural Geographies of Coastal Change

By Cormac Walsh, Hamburg University, and Martin Döring, Helmholtz-Zentrum Centrum Geesthacht

Coasts are gaining increased attention worldwide as sites of dramatic and disruptive environmental change. Coastal settlements and ecosystems are particularly vulnerable to climate change and sea level rise (Moser et al 2012). Exploitation of marine resources also contributes to coastal change, resulting in subsidence or loss of land at coastal locations, including at Louisiana and the Dutch Wadden Sea (Wernick 2014, Neslen 2017). Despite the evident interweaving of the natural and the social, the ecological, and the political at the coast, coastal geography has long been firmly positioned within the domain of physical geography with comparatively little input from human geographers. Indeed within the social sciences more generally, coastal and marine spaces have tended to be marginalised in favour of land-based narratives of societal development (e.g. Gillis 2012, Peters et al. 2018).

Physical, social, economic, and cultural processes come together at the coast, and meanings become enmeshed and intertwined. The power of the sea and the physical evidence of geomorphological change at the coast is a reminder of the materiality of place and the potential for dramatic and disruptive change. But coastal landscapes are also lived spaces, often embodying historical narratives of struggles against the sea, building coastal defences, reclaiming land, and learning to work with the daily and seasonal rhythms of a dynamic and fluid environment. In our recently published Special Section of Area on ‘Cultural Geographies of Coastal Change’ (Walsh & Döring 2018), we bring together diverse perspectives concerned with the cultural dimensions of understanding, interpreting and responding to processes of both environmental and socioeconomic change at the coast. In recognition of the need for a broad spectrum of diverse perspectives, we deliberately write of cultural geographies in the plural. Indeed our understanding of cultural geographies extends beyond the discipline of geography itself, to embrace related endeavours in the environmental humanities (Palsson et al. 2013) and the applied field of spatial planning (McElduff & Ritchie). The papers in the Special Section address issues of place attachment and climate change adaptation at the Wadden Sea coast of Germany and the Netherlands (Döring & Ratter, Van der Vaart et al, Walsh), conflicting perspectives on marine conservation in the Scottish Hebrides (Brennan), questions of land- and seascape designation in the UK (Leyshon) and pathways towards place-based coastal resilience in Ireland, North and South (McElduff and Ritchie).

Conceptually, the Special Section explores the concepts of ‘liminality’, ‘metageographies’, and the ‘coast-multiple’ in an effort to grasp the complexity of a multiplicity of ways of knowing the coast, and the potential for coastal places to occupy in-between-spaces of possibility and alterity at the boundary between the land and the sea. We emphasise the need for a reconceptualization of the coast which opens up possibilities for imagining alternative futures, of thinking the coast differently (Leyshon 2018, also Köpsel et al 2017). We thus seek to move beyond established categories of mutually exclusive land and sea spaces, natural and cultural landscapes and fixed, immovable coastlines in favour of a hybrid geography of fluid and dynamic spaces of hybrid nature-culture relations (also Ryan 2011, Satizabal & Batterbury 2017). Such spaces of possibility require inclusive processes of dialogue among a broad range of stakeholders and community interests, proactive, forward-looking leadership and informed input from the social sciences, humanities, and arts (McElduff & Ritchie 2018, van der Vaart et al 2018). It is hoped that the Special Section will provide a point of departure for future engagements with the complex geographies of socio-environmental change at the coast.

Coping with drought in Madagascar – a Role-Playing Game approach

The island nation of Madagascar is well known for its abundance of species and unique habitats. The potential loss of this impressive biodiversity, due in part to a combination of ongoing population growth and decreasing precipitation, is alarming for environmentalists and researchers. Threats to biodiversity in Madagascar have direct adverse effects on ecosystems and in turn on the people’s livelihoods, which largely depend on these diverse ecosystems.

In the Mahafaly Plateau (southwest Madagascar) periods of drought constitute a major threat to rural livelihoods, which are based around subsistence agriculture and rely on rainfall for irrigation and zebu husbandry. In face of the impacts of climate change, it is crucial that rural communities like those in the Mahafaly Plateau develop adaptation strategies. Generating knowledge about the existing adaptation strategies is essential for supporting local actors to achieve food security by safeguarding their livelihoods and the ecosystems they depend upon.

Community participation through Role-Playing Games

In transdisciplinary science, researchers integrate the knowledge of various scientific disciplines and stakeholders such as resource-users, decision-makers, and practitioners into the research process. This demand for integrative knowledge production calls for innovative and integrative methodologies. The so-called Role-Playing Game (RPG) methodology is presented in our recent publication in The Geographical Journal.

The method involves a number of stakeholders in a gaming situation where they act out (or role play) individual and collective decisions in response to particular scenarios. During the games, roles are assigned to the players, and, typically, a game board is used as a stylised representation of a real-life situation.

The Livelihood Game

A participatory role-playing game (RPG) was used to understand household strategies in Southwestern Madagascar in years where “normal” rainfall was observed and in periods of drought in. Since the thematic focus of the RPG was on the maintenance of a livelihood, the game was termed a “livelihood game”. The fictional duration of the game was four years, with each round representing one year. A satellite map of the village layout containing mapped plot boundaries was used to set the spatial and topographic context for the households’ activities.

Four household roles, ranging from relatively wealthy to relatively poor, were randomly assigned to players. To simulate the households’ decisions, players could locate their fields on the map and decide how to cultivate them. Moreover, a set of seven action cards illustrating activities like livestock farming, trade, making charcoal, and making handicrafts were also available to the players. Expenses and revenue were calculated for the end of each year and were symbolised by beans. We found that anonymisation, achieved through the random assignment of roles, encouraged participants to open up more in comparison to other forms of group workshops. Watch this video to find out more about the RPG methodology as applied in the Madagascar case https://vimeo.com/222374756. (WOCAT, Sulama).

Learning by doing and learning by failing

The results helped researchers understand the strategies different household types pursue in order to secure their livelihoods. Moreover, participants stated that they gained insights about how to improve their livelihood strategies from the in-game discussions. For example, they strategically accumulated starting capital to access more profitable livelihood activities. In times of drought, participants diversified their activities and increasingly opted to collect edible forest products or migrate temporarily.

The strength of the RPG method is that the close-to-real situations allow the creation of ‘safe, dangerous places’ (Lankford and Watson 2007, 426) where various courses of action can be tested and discussed. Furthermore, it constitutes a platform that helps to build trust, negotiate interests, and mediate conflicts between participants.

Power and empowerment

One problem associated with participatory methods is that power imbalances can arise between local research participants and non-local researchers. This means, for example, that the game, developed by non-local researchers, might be designed in a way that reflects the researchers’ prior assumptions about who holds power and who is to be empowered (Kothari 2001). In these situations, participatory approaches run the risk of reproducing such power disparities by providing a platform for those voices that are already most dominant (Mosse 2001), while marginalised groups such as women or the poorest members of the community might be sidelined.

The method requires a lot of preparation and communication skills. Therefore, it is crucial that facilitators have a good knowledge of the region and should pose critical questions when they suspect bias or distortion in participants’ answers. At the same time, they should act as neutral persons who allow all participants to contribute their knowledge and opinions. If applied in a thoughtful way, the method constitutes a powerful tool for observing players’ behaviour and eliciting their decisions in context, as well as providing a platform for the discussion of the consequences of their actions.

Exploring political-economic influences on official environmental reports

By Yonten Nyima, Sichuan University, China

Not long ago, China’s state media, Xinhua News Agency, reported that grassland cover in the Tibet Autonomous Region (TAR) has increased by 2.5% since 2010 according to the regional Department of Agriculture and Animal Husbandry (Liu, 2017; Xinhua News Agency, 2017). According to the report, the increase results from an ongoing grazing ban and a destocking policy implemented to prevent and reverse grassland degradation (Liu, 2017). Grazing has been banned on approximately 10% of the region’s total area of grassland and the number of livestock has been reduced to 18 million from 23 million in 2010, as per the report(Xinhua News Agency, 2017). The report does not detail how this increase in grassland cover was figured out. Nonetheless, my recently published Area paper suggests that it is sensible to be skeptical about the credibility of such reports as they are often influenced by political-economic factors (Nyima, 2018).

China claims that, with a total grassland area of 400 million hectares (a total usable grassland area of 313 million hectares), which it says accounts for 13% of the world’s total area of grassland and 41.7% of China’s total area of land, it has the world’s second largest grassland area after Australia (Han, 2011). Within China, the TAR is believed to have the largest grassland area with 25% of China’s usable grassland area (Han, 2011; Zhaxi, 2016). In China, narratives of grassland degradation underlie ongoing state policy on grassland management and pastoralism. As it believes that there is pervasive rangeland degradation across the country due to overgrazing, China has launched two large grassland protection programs since 2003. The programs call for grazing restrictions and destocking through a reward mechanism.

My Area paper critically examines the credibility of official reports on grassland degradation through a case study from the TAR. It analyses the political-economic motivations behind official reports on grassland degradation over two decades, between 1992 and 2011, in the region. It reveals internally inconsistent or contradictory figures and statements regarding the magnitude and extent of grassland degradation and shows political-economic factors influencing official reports on rangeland degradation. Specifically, the government tends to play down the problem of grassland degradation when it responds to criticisms for its alleged environmentally damaging activities. The opposite is true of official reports on grassland degradation produced for economic motivation, i.e. government agencies tend to overstate the problem of grassland degradation in order to capture funding. The paper concludes that political-economic motivations behind official reports on grassland degradation may prevent alternative input about the actual condition of grassland, and alternative policies to be considered and adopted.

This finding is consistent with research elsewhere in the world; non-environmental factors play an important role in shaping environmental narratives. For example, Sayre’s review of the global history of grassland science shows that grassland science is guided more by capital and the agendas of state agencies (Sayre, 2017). Another example is Davis’s study of arid lands in North Africa, which shows that desertification assessment has been politically motivated and exaggerated, and yet such assessment still frequently informs policy (Davis, 2016). Lastly, it should be stressed that pointing out that non-environmental factors shape environmental narratives is not the same as denying environmental problems, but it is vital to have a more accurate understanding of environmental realities.

Trucking Transformations

“Smokey, old diesels” – this summarizes a long-held perception of the trucking industry.  It has been, perhaps, a valid perception. Nevertheless, with electric transports entering the industry, opinions may be poised to change. Where has the trucking industry been and where is it going? How is geography going to impact the emergence of electric trucks?

Diesel exhaust has choked cities for decades. Diesel-powered transports have traditionally spewed up to 30 percent of the particulate matter (PM) in polluted urban air (Toy, Graham, & Hammit, 2000). Particulate matter in the United States alone caused 15,000 premature deaths each year (Nel, 2005). Diesel PM has been tied to increases in emphysema, asthma, and heart disease. Moreover, long-term exposure to diesel exhaust particles also poses the highest cancer risk of any toxic air contaminant (American Lung Association, n.d.).

Likewise, trucks have conventionally comprised about 10 percent of nitrogen oxide (NOx) emissions in America (Toy, Graham, & Hammit, 2000). Exposure to ground-level ozone – for which NOx is a precursor – has been linked to lung inflammation and decreased immunity (American Lung Association, n.d.). Furthermore, diesel exhaust is an irritant to mucosal membranes (eyes, nose, throat) and can precipitate coughs, headaches, lightheadedness, nausea, and allergies.

Air pollution and public health, however, are not the only concerns weighing heavy-duty vehicle transportation. Trucking accounts for approximately 20 percent of North America’s greenhouse gas (GHG) emissions (U.S. Department of Transportation, n.d.).  The preponderant GHG’s include water vapour, carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). The primary GHG’s associated with trucking are CO2, CH4, N2O, and HC (US EPA, 2010).

In the interest of public health and environmental preservation, curtailing freight truck emissions is evidently prudent. In March of 2011, President Obama announced – with liquefied natural gas (LNG) trucks as a backdrop – a public-private partnership aimed at reducing gasoline and diesel consumption in large commercial fleets. Trucking companies throughout Canada and the United States began branding themselves “green” by embracing LNG engine technology. LNG, however, has its own issues. Though inherently cleaner burning than diesel, LNG is still a fossil fuel. While natural gas is touted as having an environmental advantage over diesel in terms of life cycle (Riva, D’Angelosante, & Trebeschi, 2006), the ability to extract copious volumes of natural gas from vast shale reserves in North America still poses problems, including aquifer contamination, water use, fracking fluid impacts, land industrialization, and fugitive emissions (Verrastro & Branch, 2010).  And although LNG has had a rather exemplary safety record, fears about attacks, vapour cloud fires, and accidental spills have been raised.

Electrics, hybrids, LNG’s, diesels with particulate filters/selective catalytic reduction – technology has always driven change in the trucking industry. Simpler solutions –reducing truck idling time, installing speed limiters, training “green” drivers, and improving service inefficiencies – also reduce fossil fuel consumption. Yet, an even more obvious answer exists: reduce vehicle miles driven! How senseless it seems to transport bottles of water thousands of miles when, for many, potable water is available from a kitchen faucet. How peculiar that we opt to move millions of pounds of food that could be grown in backyard gardens. Regardless, the foremost dilemma with solutions aimed at resolving these peculiarities is that it places the burden on humanity; it would encompass a difficult social paradigm shift.

Fortunately for humanity, technology marches on. The new year rolled in with big trucking news – the Tesla semi-truck. Though not the first electric semi-truck, the Tesla has an enviable range of up to 800 km (Clouthier, 2018). Ultimately, however, geography will determine any realized range. Temperature, wind, grade, payload, traffic, and topography will all influence actual range. Regardless, fewer fossil-fuel-powered trucks on the road is good news in terms of air quality and GHG emissions (assuming renewable electric generation). Again, this assumption is highly dependent upon geography; it obviously makes more sense to run electric trucks in areas where electricity is generated from renewable sources.

Even with consideration of all these existing variables, there is still one major hurdle electric trucks must overcome, one that that share with passenger vehicles – adequate recharging networks. In a recent paper that highlights strategies to increase electric vehicle uptake, the absence of recharging stations is earmarked as a key concern among potential customers. Surveys indicate that some drivers are more concerned about inadequate infrastructure than vehicle cost (Broadbent, Drozdzewski & Metternicht, 2017). The authors go on to state that faster transition to electric vehicle adoption should include appropriate legislation, sufficient recharging networks, procurement programs, and information programs. Adoption of electric semi-trucks would surely benefit from similar programs. Realizing these objectives will not be easy, but certainly worth it – for the health of the public and the planet.

Improving Learning and Applying GIS in Interdisciplinary Research

By Patrick Rickles, UCL

I guess I’m not alone in either struggling with GIS (Geographic Information System) technologies, or seeing colleagues struggle to effectively use it. When the GIS does not work, or when learning resources use jargon that the would-be GIS users do not understand, they tend to blame themselves. This should not be the case – though never intentional, badly designed systems, materials or practices should be held accountable and either improved or completely rethought. These problems exist, regardless of discipline, when using GIS.

My professional experience includes working in private, public and academic sectors, across a variety of industries, and I have seen this same issue continually arise – enthusiasm turning to frustration when people cannot do what they want to do with the GIS, so they abandon the technology. As GIS professionals, I believe we have a duty to do better and promote the overall understanding of GIS and associated materials, to improve the likelihood of success and uptake. It is my hope that through my research, we can learn how to better support an increasingly diverse range of GIS users, foster that enthusiasm for GIS and create a better and more inclusive community of practice with and around GIS.


Patrick Rickles helping an interdisciplinary researcher learning GIS

My recently published article, published in Geo: Geography and Environment, titled “A suggested framework and guidelines for learning GIS in interdisciplinary research”, is based upon my PhD research and has been written with co-authorship and support from my supervisors, Claire Ellul and Muki Haklay. In the article, I share elements of my PhD work which focused on how people go about learning to use GIS, particularly in the context of interdisciplinary research. From this work, I make recommendations on how these results can be used, going forward, to improve the process of learning GIS for future learners.

To begin, I had to first understand what interdisciplinary researchers were doing with GIS and the issues they faced that might affect uptake. These preliminary findings were discussed in Rickles & Ellul (2015), which identified challenges and suggested solutions in interdisciplinary research, as well as a theoretical understanding of learning approaches. Based on an evaluation of prominent interdisciplinary studies using GIS, and observations of an interdisciplinary team’s use of GIS, the relevance of those challenges and suggested solutions were reviewed to support a learning approach. The knowledge gap and time constraints were the most common challenges, with building relationships and training often suggested as solutions.  Problem Based Learning (PBL) – where learners restructure their knowledge to solve real world problems as part of a collaborative process with other learners and/or educators – was put forward as a viable approach for learning GIS in interdisciplinary research.


Modified Technological Pedagogical and Content Knowledge (TPACK) framework for learning GIS in interdisciplinary research

This article provides updates to and further enriches that initial research. An online survey of interdisciplinary researchers provided verification of the issues uncovered in the first article, with interviews providing a more in-depth exploration of what those issues may mean in a practical sense. An overview of those findings shows that interdisciplinary researchers are using GIS to create, analyse and visualise information; that they are using ArcGIS and QGIS desktop platforms as well as web GIS platforms such as Google Maps/Earth and ArcGIS Online; and that they are using informal learning methods (e.g. internet searches, watching a video, asking a more experienced person). The findings also suggest a more structured learning approach may be supportive of the learner, but PBL can be time consuming for both the learner and educator. Therefore, Context Based Learning (CBL), which recognises the importance of the context of the problem domain for the learning activity, but allows for materials to be created in advance, may be a more appropriate approach. Combining these elements, which modify the Technological, Pedagogical and Content Knowledge (TPACK) framework, guidelines and a specific framework are suggested for educators to use to support interdisciplinary researchers learning GIS. My further research has applied these in a practical setting using a learning resource titled “GIS Lessons for You” (www.patrickrickles.com/tutorial), to test the guidelines and framework. The results will be published as part of my PhD and potentially as a future article.
