Mountain fires burning higher at unprecedented rates

Climate change to blame for making high-elevation forests particularly susceptible to blazes





















MCGILL UNIVERSITY

Research News

Forest fires have crept higher up mountains over the past few decades, scorching areas previously too wet to burn, according to researchers from McGill University. As wildfires advance uphill, a staggering 11% of all Western U.S. forests are now at risk.

"Climate change and drought conditions in the West are drying out high-elevation forests, making them particularly susceptible to blazes," says lead author Mohammad Reza Alizadeh, a PhD student at McGill University under the supervision of Professor Jan Adamowski. "This creates new dangers for mountain communities, with impacts on downstream water supplies and the plants and wildlife that call these forests home."

Climate warming has diminished 'flammability barrier'

In a study published in Proceedings of the National Academy of Sciences, the researchers analyzed records of fires larger than 405 hectares in the mountainous regions of the contiguous Western U.S. between 1984 and 2017. Their results show that climate warming has diminished the 'high-elevation flammability barrier' - the point where forests historically were too wet to burn regularly because of the lingering presence of snow. The researchers found that fires advanced about 252 meters uphill in the Western mountains over those three decades.

The amount of land that burned increased across all elevations during that period, however the largest increase was at elevations above 2,500 meters. Additionally, the area burning above 8,200 feet more than tripled in 2001 to 2017 compared with 1984 to 2000. Over the past 34 years, rising temperatures have extended fire territory in the West to an additional 81,500 square kilometers of high-elevation forests, an area similar in size to South Carolina.

"Climate change continues to increase the risk of fire, and this trend will likely continue as the planet warms. More fire activity higher in the mountains is yet another warning of the dangers that lie ahead," says co-author Jan Adamowski, a Professor in the Department of Bioresource Engineering at McGill University.

Managed retreat: A must in the war against climate change

New research finds that moving off the coast and away from floods can expand options

UNIVERSITY OF DELAWARE

University of Delaware disaster researcher A.R. Siders said it's time to put all the options on the table when it comes to discussing climate change adaptation.

Managed retreat -- the purposeful movement of people, buildings and other assets from areas vulnerable to hazards -- has often been considered a last resort. But Siders said it can be a powerful tool for expanding the range of possible solutions to cope with rising sea levels, flooding and other climate change effects when used proactively or in combination with other measures.

Siders, a core faculty member in UD's Disaster Research Center, and Katharine J. Mach, associate professor at the University of Miami Rosenstiel School of Marine and Atmospheric Science, provide a prospective roadmap for reconceptualizing the future using managed retreat in a new paper published online in Science on June 17, 2021.

"Climate change is affecting people all over the world, and everyone is trying to figure out what to do about it. One potential strategy, moving away from hazards, could be very effective, but it often gets overlooked," said Siders, assistant professor in the Joseph R. Biden, Jr. School of Public Policy and Administration and the Department of Geography and Spatial Sciences. "We are looking at the different ways society can dream bigger when planning for climate change and how community values and priorities play a role in that."










Retreat does not mean defeat

Managed retreat has been happening for decades all over the United States at a very small scale with state and/or federal support. Siders pointed to Hurricanes Harvey and Florence as weather events that caused homeowners near the Gulf of Mexico to seek government support for relocation. Locally, towns such as Bowers Beach, near the Delaware coast, have used buyouts to remove homes and families from flood-prone areas, an idea that Southbridge in Wilmington is also exploring.

People often oppose the idea of leaving their homes, but Siders said thinking seriously about managed retreat sooner and in context with other available tools can reinforce decisions by prompting difficult conversations. Even if communities decide to stay in place, identifying the things community members value can help them decide what they want to maintain and what they purposely want to change.

"If the only tools you think about are beach nourishment and building walls, you're limiting what you can do, but if you start adding in the whole toolkit and combining the options in different ways, you can create a much wider range of futures," she said.

In the paper, Siders and Mach argue that long-term adaptation will involve retreat. Even traditionally accepted visions of the future, like building flood walls and elevating threatened structures, will involve small-scale retreat to make space for levees and drainage. Larger-scale retreat may be needed for more ambitious transformations, such as building floating neighborhoods or cities, turning roads into canals in an effort to live with the water, or building more dense, more compact cities on higher ground.

Some, but not all these futures currently exist.

In the Netherlands, the municipality of Rotterdam has installed floating homes in Nassau harbor that move with the tides, providing a sustainable waterfront view for homeowners while making room for public-friendly green space along the water. In New York City, one idea under consideration is building into the East River to accommodate a floodwall. Both cities are using combination strategies that leverage more than one adaptation tool.

Adaptation decisions don't have to be either/or decisions. However, it is important to remember that these efforts take time, so planning should begin now.

"Communities, towns, and cities are making decisions now that affect the future," said Siders. "Locally, Delaware is building faster inside the floodplain than outside of it. We are making plans for beach nourishment and where to build seawalls. We're making these decisions now, so we should be considering all the options on the table now, not just the ones that keep people in place."

According to Siders, the paper is a conversation starter for researchers, policymakers, communities and residents that are invested in helping communities thrive amid changing climate. These discussions, she said, shouldn't focus solely on where we need to move from, but also where we should avoid building, where new building should be encouraged, and how we should build differently.

"Managed retreat can be more effective in reducing risk, in ways that are socially equitable and economically efficient, if it is a proactive component of climate-driven transformations," said Mach. "It can be used to address climate risks, along with other types of responses like building seawalls or limiting new development in hazard-prone regions."

Globally, Siders said the U.S. is in a privileged position, in terms of the available space, money and resources, relative to other countries facing more complicated futures. The Republic of Kiribati, a chain of islands in the central Pacific Ocean, for example, is expected to be under water in the future. Some of its islands already are uninhabitable.

The Kiribati government has bought land in Fiji for relocation and is developing programs with Australia and New Zealand to provide skilled workforce training so the Kiribati people can migrate with dignity when the time comes. Challenges remain, though, since not everyone is on board with moving.

In a recent special issue of the Journal of Environmental Studies and Sciences, edited and introduced by Siders and Idowu (Jola) Ajibade at Portland State University, researchers examined the social justice implications of managed retreat in examples from several countries, including the U.S., Marshall Islands, New Zealand, Peru, Sweden, Taiwan, Austria and England. The scientists explored how retreat affects groups of people and, in the U.S., specifically considered how retreat affects marginalized populations.

So, how can society do better? According to Siders, it starts with longer-term thinking.

"It's hard to make good decisions about climate change if we are thinking 5-10 years out," said Siders. "We are building infrastructure that lasts 50-100 years; our planning scale should be equally long."

Siders will give a keynote address and research presentation on the topic at a virtual managed retreat conference at Columbia University, June 22-25, 2021.

How much do traditional practices contribute to the protection of local biodiversity? Why and how are sacred groves locally valued and protected, and how can this be promoted and harnessed for environmental protection? Working together with the University of Kurdistan, researchers of the University of Göttingen and the University of Kassel have examined the backgrounds of this form of local environmental protection in Baneh County, Iran.

"Around the world, local communities are voluntarily protecting certain parts of their surroundings due to religious reasons - be it in Ethiopia, Morocco, Italy, China or India", reports Professor Tobias Plieninger, head of the section Social-ecological Interactions in Agricultural Systems at the universities of Kassel and Göttingen. Sacred natural sites are places where traditional myths and stories meet local ecological knowledge and environmental protection. Beyond state-based protection programs, these form a network of informal nature reserves.

In the contested border areas between Iran and Iraq, state-run environmental protection programs are often failing, while natural resources are under a lot of pressure. Even in such areas of conflict, patches of highly biodiverse woodlands still exist thanks to informal conservation traditions - in the form of decades-old sacred natural sites, some of which are known as the 'sacred groves'.

In the Middle East, sacred groves are quite common, but there has been very little research into these biocultural hotspots. They usually belong to a Mosque and serve as village cemeteries, the use of which is strictly regulated. Even though they usually cover only a small area - 1 hectare on average - they are comparatively rich in biodiversity, provide numerous ecosystem services and are of great cultural and spiritual importance to local communities.

Local people regard them as the abodes of their ancestors. Dr Zahed Shakeri, who accompanied the project as a post-doc researcher and grew up in the region himself, reports on the numerous myths and legends that surround these sites and demand a careful maintenance as well as respectful behavior. "Our research group developed a fascination for the botanical treasures of these sites," Plieninger tells. In a vegetation study, they found out that the taxonomic diversity in sacred groves is much higher than in neighboring cultivated lands. The vegetation composition, too, is fundamentally different here.

"The 22 sacred groves examined comprised 20% of the flora of the whole region. Moreover, they host multiple rare and endangered plants, and represent complex niches for threatened animals", Shakeri reports. "Due to this taxonomic diversity, sacred groves can serve as an important complement to formally protected areas in the region, and as baselines in their reconstruction." Today, due to changes in customary rights, population growth and the loss of traditional faiths, the number and condition of such sacred natural sites are decreasing around the world. Thus, local people's perceptions regarding sacred groves as well as the reasons for their relatively good condition in the region were also subject of this research.

On the basis of interviews with 205 residents from 25 villages, the research group identified people's key motivations for the areas' protection: in particular spiritual values, the preservation of cultural and spiritual heritage as well as of local biodiversity played a role here. Furthermore, the importance of taboos became clear, which particularly prohibit the use of natural resources (for instance forest clearance, hunting and livestock grazing) and road construction, but also regulate the general behavior within these sites.

Even though these social values and taboos are considered relatively stable in the province of Kurdistan, the interviewees repeatedly referred to the threatened situation of the groves in the region. Especially elderly and rural people, women and people with traditional lifestyles were regarded as the holders of these values and taboos. "Protection programs could support these groups to defend and revive their customs. At the same time, young and urban people with modern lifestyles represent an important target group for awareness-raising," Shakeri summarizes.

The example of sacred groves demonstrates that social dynamics and especially cultural values deserve greater attention in environmental protection: "Such a biocultural approach to conservation that considers different worldviews and knowledge systems, could translate social taboos and the related land-use practices into socially acceptable and environmentally effective conservation outcomes", Plieninger concludes.

Excess nitrogen puts butterflies at risk

UNIVERSITY OF BASEL

Research News

Nitrogen from agriculture, vehicle emissions and industry is endangering butterflies in Switzerland. The element is deposited in the soil via the air and has an impact on vegetation - to the detriment of the butterflies, as researchers at the University of Basel have discovered.

More than half of butterfly species in Switzerland are considered to be at risk or potentially at risk. Usually, the search for causes focuses on intensive agriculture, pesticide use and climate change. A research team led by Professor Valentin Amrhein from the University of Basel, however, has been investigating another factor - the depositing of nitrogen from agriculture and exhaust fumes from industry and traffic in soils via the air. In the journal Conservation Biology, the research team reports a connection between this unintentional fertilization and the low diversity of butterflies in Switzerland.

It was already known from previous studies that too much nitrogen leads to denser vegetation, but with a smaller selection of plant species. Nitrogen stimulates the growth of less demanding plants in particular, with more specialized species being displaced. "We wanted to find out whether a nitrogen surplus also indirectly affects the diversity of butterflies via this change in vegetation," explains Dr. Tobias Roth, lead author of the study.

The team analyzed data from Biodiversity Monitoring Switzerland on the diversity and prevalence of plants and butterflies on 383 plots throughout Switzerland. The result was clear: the more nitrogen introduced via the air to the areas studied, the less diverse the vegetation and hence the butterfly species.

"As caterpillars, some butterfly species need certain plant species as food, or are dependent on a certain microclimate," Roth explains. Over-fertilization results in open, warm and dry places becoming cooler, shadier and damper due to stronger plant growth.

The nitrogen surplus impacts the prevalence of a large number of butterfly species in Switzerland, such as those that prefer open and dry sites. The researchers saw the clearest effect in rare and endangered species. "Nitrogen from the air is likely to be an important factor in the reason why these species are endangered," Roth remarks.

Existing literature on the diversity of butterflies explains the presence or absence of species primarily in terms of habitat quality or climate. A literature review by the research team revealed that plant diversity and vegetation density have so far received less attention. "We believe that the impact of nitrogen enrichment on butterflies has been underestimated," says Amrhein. Nitrogen appears to play a similarly extensive role as climate change when it comes to butterfly diversity.

While the researchers do not see a simple approach for improving the situation, technical improvements continue to offer a certain potential. "In the past, slurry was sprayed on farmland, for example, and some of this was transferred to other areas of land by the wind," Roth explains. Today, he says, drag hoses are used increasingly to apply the slurry directly to the soil. This reduces nitrogen input via the air to other areas where it is not wanted.

In addition, buffer zones and adapted landscape management can also help to partially mitigate the negative impact on sensitive habitats: this includes measures to prevent scrub encroachment, such as grazing or more frequent mowing. This is beneficial not only for demanding plant species, but also for butterflies. According to the researchers, however, there is ultimately no way around environmentally friendly consumer behavior when it comes to reducing unwanted nitrogen input, for example through the reduction of vehicle emissions and livestock farming. Around two thirds of nitrogen input into sensitive ecosystems in Switzerland today originate from ammonia emissions from livestock farming.

The surface of a material often has properties that are very different from the properties within the material. For example, a non-conducting crystal, which actually exhibits no magnetism, can show magnetisation restricted to its surface because of the way the atoms are arranged there. These distinct properties at interfaces and surfaces of materials often play a key role in the development of new functional components such as optoelectronic chips or sensors and are therefore subject to extensive research. An international research team from the University of Göttingen, the Max Planck Institute for Biophysical Chemistry Göttingen and the National Research Council Canada has now succeeded in investigating the surfaces of transparent crystals using powerful irradiation from lasers. The results of the study were published in the journal Nature Communications.

The researchers describe their method, which relies purely on light, to determine electrical and magnetic properties on surfaces. This new method could play an important role in the investigation of transparent, non-conductive materials, as established methods using electrons often experience experimental limitations due to low conductivity, among other difficulties. The use of light helps get around these limitations: when light rays hit a material surface, for example a glass pane, they are reflected at the interface, refracted and absorbed into the material. These effects, which can be observed in everyday life, are the result of the interaction of the weak light field with the atoms and electrons of the irradiated material. In the case of stronger light fields, which are achieved with lasers, further effects occur, which can, for example, generate higher light frequencies - known as high harmonic radiation. These effects are often dependent on the direction of oscillation of the light field relative to the atomic arrangement in the material.

"We take advantage of this dependence when generating high harmonic radiation to gain insights into the properties at and near the surface of transparent materials," says first author and PhD student Tobias Heinrich from the Faculty of Physics at Göttingen University. "The light field we use is composed of two laser pulses rotating in opposite directions at two different frequencies, and this results in a cloverleaf-shaped symmetrical field." These tailor-made light fields can be adapted to the atomic arrangement of the material to control the generation of the high harmonics.

"We show that this control can be used to study magnetisation at the surface of magnesium oxide," explains Dr Murat Sivis, the study lead. Depending on the direction of rotation of the light field - also called chirality - the generated ultraviolet light is absorbed to different degrees at the interface. "For various materials that do not actually exhibit magnetisation or electrical conductivity, these properties at the surface have been predicted in theory," Sivis said. "In our study, we show that it is now possible to investigate such phenomena using just optical methods, probably even at very short time scales." The researchers also hope to gain new insights into the electronic properties of other chiral materials, as the study shows using the example of the helical crystal structure of quartz. The sensitivity to chiral phenomena on surfaces could potentially open up new opportunities for research into innovative functional materials.

'First empirical evidence of an identity-related societal cleavage'

CLUSTER OF EXCELLENCE "RELIGION AND POLITICS"

Research News

An international survey by the University of Münster's Cluster of Excellence "Religion and Politics" provides the first empirical evidence of an identity-related political cleavage of European societies that has resulted in the emergence of two entrenched camps of substantial size. "We see two distinct groups with opposing positions, which we call 'Defenders' and 'Explorers'", says psychologist Mitja Back, spokesperson of the interdisciplinary research team that conducted the most comprehensive survey of identity conflicts in Europe to date. "Who belongs to our country, who threatens whom, who is disadvantaged? Across all such questions of identity, the initial analyses of the survey reveal a new line of conflict between the two groups, which have almost diametrically opposite opinions. In debates over identity, these opinions have hardened into seemingly irreconcilable conflicts. The study could open up new avenues to tackle these conflicts".

The two camps together account for a significant proportion of citizens in all countries: more than one-third in Germany (Fig. 3.1) and almost three-quarters in Poland (Fig. 3.4). In liberal democratic states like Germany, the proportion of 'Defenders' is 20% and that of 'Explorers', 14%. In France and Sweden, 14% and 29% 'Defenders', and 11% and 15% 'Explorers', respectively, were observed. In a semi-authoritarian country like Poland, where according to the researchers the government provides populist support to the 'Defenders' opinions, the proportion of both groups combined is 72%. "This shows how much the conflict can escalate in a country: the polarized positions can grow to form the majority", says Mitja Back. "The degree to which a population becomes polarized and how far feelings of threat and narrow ideas of identity also entail feelings of disadvantage and mistrust therefore vary depending on the political system. This suggests that identity conflicts are open to political influence".

Who are 'Explorers' and 'Defenders'?

5,011 respondents in Germany, France, Poland and Sweden took part in the survey, which the Cluster of Excellence conducted with "Kantar Deutschland" at the end of 2020. Its authors are the sociologists Detlef Pollack and Olaf Müller, the psychologists Mitja Back and Gerald Echterhoff, and the political scientist Bernd Schlipphak. Their Working Report, "Of Defenders and Explorers: An identity conflict over belonging and threat" (http://go.wwu.de/izpgb), provides initial results. Drawing on the detailed results on more than 20 questions examined, they used cluster analyses to form groups comprising people with very similar attitudes and displaying strong differences one from the other. This yielded the patterns of 'Explorers' and 'Defenders' across all questions.

In all countries, the 'Defender' group largely endorse a narrow definition of who belongs to their country, with only those belonging who were born in the country, have ancestors of the ethno-national majority, and/or belong to the dominant religion. They therefore defend traditional criteria such as ethnic and religious homogeneity. At the same time, 'Defenders' feel rather threatened by foreigners such as Muslims and refugees, and consider themselves rather disadvantaged. They are also more dissatisfied with democracy and more distrustful of political institutions.

The 'Explorer' group, on the other hand, reject a narrow definition of belonging based on ethno-religious criteria. Its members do not feel threatened by foreigners, but instead see immigration and growing diversity as an opportunity, and they also advocate a society with many notions of life oriented towards equality. They see themselves as being well represented by the political system, are more satisfied with democracy, and are more likely to trust political institutions. In semi-authoritarian Poland, however, where the government provides populist support to 'Defenders' positions on ethno-religious homogeneity and protection against foreigners, the 'Explorers' also feel disadvantaged and are dissatisfied with democracy and government.

The two groups also differ strongly in cultural, religious, psychological and social terms (Figs. 3.6 and 3.7), with 'Defenders' in all countries being far more attached to home and religious than 'Explorers'. The former also have a stronger preference for social hierarchies and trust other people less, while the reverse is true of the latter. 'Explorers' also tend to be quite young, highly educated, more likely to live in a city, and less likely to be affected by socio-economic hardship. Except in Poland, 'Defenders' are more likely than 'Explorers' to be found among the elderly and the low educated. They tend to live in rural areas and, again with the exception of Poland, consider themselves to have a lower social status.

Political effects and recommendations

The cultural conflict also has strong political effects: 'Defenders' favour populist parties and believe much more in the concept of a "strong leader"; they are also prone to conspiracy theories and advocate elements of direct democracy. 'Explorers' hold diametrically opposed views. For example, 26% of 'Defenders' in Germany and 57% in Poland are likely to vote for a populist party (Fig. 6.6), while 'Explorers' tend not to.

According to the researchers, this can represent fundamentally different concepts of politics: 'Defenders' favour concepts more in line with anti-pluralist ideas that claim that political regulations should express a single popular will; 'Explorers', in contrast, share attitudes more compatible with pluralist ideas that claim that politics is a process of negotiation and compromise between different interests. Mitja Back: "A person's positioning in the conflict as 'Explorer' or 'Defender' can have a strong impact on the form of democracy desired. Cultural conflicts over identity have therefore become very entrenched politically, and now structure the population's social and political views to a significant extent".

By linking their results to other insights from current research, the authors see the polarized positions as being rooted in fundamental and rather stable psychological needs of varying strength, such as security and stability ('Defenders'), or openness and change ('Explorers'). According to the report, this implies that societies are always composed of a mixture of 'Explorers' and 'Defenders'. In contrast to more material conflicts, the identity conflict is therefore more difficult to negotiate, and especially so when ideas of identity are framed in religious or fundamentalist terms. Identity conflict is also exacerbated by the effects of globalization, such as migration, increasingly supranational instead of national policies, and crises such as the financial crisis and the Covid 19 pandemic. "This makes questions of identity - who belongs to the country, or who triggers feelings of threat - all the more urgent".

The researchers therefore urge politicians to refrain from taking one of the two sides. Neither in liberal democracies nor in authoritarian countries has this led to movement in entrenched conflicts, as at least one group always feels excluded. Rather, it is important to take the underlying psychological needs on both sides seriously, and to understand them as social resources, while tracing the sometimes widely divergent demands of both groups back to their functional core. "In this way, it is possible to filter out which positions are not acceptable to each group, and which are open to negotiation. Only by doing so can we find a basis for compromise that currently seems impossible, as well as space for dialogue without one side devaluing the other". (vvm/sca)

Detailed results behind the core findings: a selection

The researchers back up their core findings on the groups of 'Defenders' and 'Explorers' with detailed results for individual countries and for the factors that determine the identity conflict.

Results underline that 'Defenders' and 'Explorers' occupy polarized positions. In Germany, for example, 61% of 'Defenders' advocate a narrow definition of ethno-religious belonging; 49% feel threatened by Muslims, and 55%, by refugees; 45% feel culturally disadvantaged; and only 21% are satisfied with democracy, with only 11% trusting the government and parliament. In contrast, in the group of 'Explorers', less than 15% have a narrow, ethno-religious definition of belonging, none feel threatened or marginalized, and a large majority (93%) are satisfied with democracy and trust political institutions (the federal government, 100%; the EU, 99%). Similar results were obtained for France and Sweden.

Poland is an exception. In this semi-authoritarian country, where the government supports 'Defenders' positions such as the desire for ethno-religious homogeneity and protection against foreigners, 29% of 'Defenders' and 49% of 'Explorers' feel politically marginalized. The latter are also dissatisfied with democracy in the country and distrust the government, whereas they have a high level of trust in the EU (74%). 'Defenders' in Poland are satisfied with democracy in the country (57%), and have a high level of trust in the government and parliament (72%), but far less trust in the EU (32%). Society is much more divided than it is in other countries, with 'Explorers' and 'Defenders' making up 72% of the population in Poland. "The example of Poland shows that the political system and political communication influence how divided a society is, and how much each group feels marginalized and accepts democratic institutions".

In Germany, the two groups differ in socio-cultural, religious and psychological terms as follows: in the 'Defender' group, 33% have a high level of religiosity, 52% feel more attached to home than to the world, 34% believe in social hierarchies, and 31% are sceptical of other people. In contrast, 24% of 'Explorers' are strongly religious, 31% have a strong attachment to home, 4% believe in social hierarchies, and 3% have little trust in people. The other countries show similar tendencies here. (vvm/sca)

Survey methods

The Working Report "Of Defenders and Explorers: An identity conflict over belonging and threat" presents results of a survey conducted at the University of Münster's Cluster of Excellence "Religion and Politics" as part of the project "Threat perceptions, feelings of belonging, acceptance of democratic rule: A new religiously shaded line of conflict in Europe?" Its authors are the sociologists Detlef Pollack and Olaf Müller, the psychologists Mitja Back and Gerald Echterhoff, and the political scientist Bernd Schlipphak.

  • Survey fielded via random sampling in four European countries (Germany, France, Poland and Sweden) in line with the highest methodological standards

  • Survey period: 9 November to 18 December 2020
    • 5,011 participants (in Germany, 1,402; 506 of whom from the five federal states in the east and Berlin; in France, 1,208; in Poland, 1,200; in Sweden, 1,201)
    • CATI procedure (CATI: Computer Assisted Telephone Interviewing)
    • Consideration of landline and mobile phone numbers (dual-frame sampling design)
    • Conducted by the market research company "Kantar Deutschland" (Berlin)

Participants answered questions on ten themes (see overview below), initially on the following four factors that are central to identity conflict: definitions of national belonging, feelings of threat, feelings of disadvantage, and perception of political representation and governance. Added to these were cultural, religious and psychological factors, as well as social characteristics such as age, gender, education and region, which at the end were weighted to avoid bias. Most factors are composed of several individual questions (items).

The researchers applied the statistical instrument of cluster analysis to the detailed results on all factors examined. Cluster analyses enable researchers to find out whether the landscape of opinions shown by the survey can yield distinct social groups in the identity conflict. The existence of such distinct social groups has been discussed, but not yet empirically verified. The study demonstrated two consistent groups across all factors and countries, whose members show very similar attitudes, and who as groups show strong differences from each other. This resulted in the pattern of 'Explorers' and 'Defenders'. (sca/vvm)

Structure of the survey

A) Factors determining identity conflict

1) Definitions of national belonging (such as questions about an ethno-religious definition of belonging)

Example question: "Some people think that the following things are important to be a real German. Others think that they are not important. How do you rate these things? In your opinion, to be a real German, is it very important, quite important, not very important, or not important at all that a person ...

  • has been born in Germany?
  • has lived in Germany for most of her life?
  • is a Christian?
  • has German ancestors?"

2) Threat perceptions (e.g. questions about feelings of threat from Muslims and refugees, since these minority groups most often appear in discourses of belonging)

Example questions (agree/disagree): "Muslims threaten our way of life and our values in Germany", "The values and beliefs of Muslims are not compatible with the general values and beliefs in Germany", "Muslims threaten the economic situation in Germany", "Muslims living here threaten public safety in Germany", "Because of Muslims, there are more acts of violence in Germany"

3) Feelings of disadvantage (such as questions about economic, political and cultural recognition or marginalization)

Example questions (agree/disagree): "The work of people like me is not recognized enough in society", "No matter how hard we work, people like me are not appreciated", "The problems of people like me are unimportant to most politicians", "Most politicians do not care what people like me think", "The values of people like me have are becoming less and less important in society", "The customs, traditions, and manners of people like me are less and less appreciated"
