Exploring Tangible and Intangible Heritage and its Resilience as a Basis to Understand the Cultural Landscapes of Saxon Communities in Southern Transylvania (Romania)

: Landscape researchers tend to reduce the diversity of tangible heritage to physical aspects of cultural landscapes, from the wealth of intangible heritage they focus on land-use practices which have a direct and visible impact on the landscape. We suggest a comprehensive assessment of both tangible and intangible heritage, in order to more accurately assess the interconnection of local identity and the shaping of cultural landscapes. As an example, we looked at Saxon culture and cultural landscapes in southern Transylvania (Romania), where we assessed features of tangible and intangible cultural heritage, identiﬁed their resilience and the driving forces of their change. Our analysis, based on 74 interviews with residents in ten villages in southern Transylvania, showed a high resilience of tangible heritage and a low resilience of intangible heritage. A major factor responsible for changes in the Saxon heritage was a decline in the population at the end of the Cold War, due to migration, driven by political and economic factors. We conclude by discussing the speciﬁc merits of such an analysis for integrated landscape management.


Introduction
In recent years, landscape research has shown a growing interest in questions of cultural heritage, acknowledging for example, its relevance for biodiversity, recreational potential, aesthetics and the social fulfillment of cultural landscapes. Cultural landscapes with high heritage value are threatened today [1] by accelerated and drastic socio-economic and environmental changes at the local and global scale [2]. The close ties between heritage and cultural landscapes are also core to the European Landscape Convention [3]. However, landscape research has to date not addressed the diversity of aspects linked to heritage adequately, as much more attention has been given to tangible heritage, such as the remains of traditional agricultural landscapes and their spatial arrangements or structures, and much less so to intangible heritage, such as practice, knowledge, skills or traditions [4,5]. Such The appearance of the Saxon communities in Transylvania is related to the Ostsiedlung, a process of colonization of eastern-central Europe by German-speaking people [26]. The first Saxon settlers came to Transylvania in the middle of the 12th century [27]. They decided to move to Transylvania based on the guarantee that they would have the privilege to exercise their traditional rights, e.g., to live freely according to their own system of values, regulations, and beliefs. They were also granted the right to choose their management bodies, mayors, judges, and advisers [28]. These rights allowed Saxon communities to form and develop, such that they preserved their ethnic, linguistic, and history identities over centuries [29]. The traditional Saxon community was considered in [30] as a bidimensional, integrated ethnic and religious community, by stressing the unity between the Evangelical Church and the ethnic society for Saxons. The Transylvanian Saxons brought several contributions to the development of Saxon culture, for example, introducing compulsory primary schools from the Middle Ages, which was further developed until 1948 into a religious school network up to middle school and high school levels [31]. The Saxons formed an independent socio-ethnic entity in Transylvania, meaning a legal and linguistic community with high social cohesion, also called the "Saxon Nation" [29,32].
The Saxons left a significant mark in southern Transylvania in the built heritage, linked to a specific form of village planning [33]. The regular form of parallel streets, the layout of the fortified church in the center and the architecture of the houses were specific features of Saxon settlements. The preservation of a fortified church in the village's territory and its location in the center of the settlement represents a specific manner of management of the territory [34]. Given the peculiarities of the territorial arrangement, the authenticity of the vernacular architecture, the integrity and outstanding value that they preserve [35], some representative Transylvanian villages with fortified churches (such as Biertan, Prejmer, Viscri, Dârjiu, Saschiz, Câlnic, Valea Viilor) were included in the World Heritage List of the United Nations Educational, Scientific and Cultural Organization [35].
The construction techniques of Saxon houses were orally passed on from father to son, supported by popular artisans. The features imposed by the Saxons in architecture are especially related to the form of the roof (triangular), the structure of the house and the existence of an "attic window" [36], which allowed ventilation. The most dominant architectural element, still visible today, is the Saxon gate model, the "wall gate", which is unique in Romania [36]. The gate gave the houses an appearance of a mini citadel, with an increased degree of safety.
Another important Saxon influence on the cultural landscape is related to specific agricultural activities, as self-sustenance was the basis of the traditional Saxon household. The Saxons produced most household products through their own collective work [37]. Saxon communities in Transylvania followed specific internal rules based on the so-called principle of neighborhood [38]. For instance, administrative work was shared, and they divided their responsibilities (e.g., sweeping the streets on Saturdays, clearing snow), equipment, such as tractors and threshing machines, was also shared. Saxon schools were built in the same spirit, through a donation system: Some donated land, others donated construction materials, and the community worked together to build the schools.
Saxon communities persisted over many centuries, despite major historical and political turmoil at European or at the local scale. The 20th century however brought major changes including deportations, expropriations, and mass emigration. The latter phenomenon is specific for the Saxon people in Transylvania [39]. Mass emigration started in the 1980s [40] and continued after the fall of the communism, particularly at the beginning of the 1990s, when approximately 200,000 people of German ethnic background emigrated from Romania [41].
In this paper, we explore the tangible and intangible heritage in cultural landscapes of Saxon communities, with a specific focus on the resilience of heritage to various external and internal driving forces. The aim of the study is to investigate the following questions: (i) What are the main elements of tangible and intangible heritage perceived by the Saxon people? (ii) How resilient are these elements? (iii) What were the major driving forces causing important changes? We consider our methods as a contribution towards more encompassing analyses of interrelationships of societies and landscapes, aiming towards a more comprehensive integration of issues related to heritage in sustainable landscape development.

Transylvania is a province of Romania, located inside the Carpathian arc ( Figure 1). The landscape of Transylvania was heavily shaped by Saxon settlers who, in the course of eight centuries, left long-lasting traces in architecture, settlement structure and agricultural landscapes [42]. We selected nine villages in southern Transylvania which are recognized for preserving traditional Saxon cultural values and in which Saxon communities are still present. Four villages, i.e., Biertan, Cârţa, Mălăncrav, and Şelimbăr, are located in the Sibiu County (No. 1 in Figure 1), and five villages, i.e., Hălchiu, Hărman, Prejmer, Sânpetru, and Vulcan, are situated in the Braşov County (No. 2 in Figure 1). It is worth noticing that the villages Biertan (since 1993) and Prejmer (since 1999) are two of the seven villages with fortified churches in Transylvania included in the UNESCO World Heritage List. All villages are situated in a sub-mountainous region, where the favorable climate and fertile soils allowed the development of highly diversified agriculture. All villages have shown a distinct and more or less steady decline in the size of the Saxon population in the last century, shrinking from 50-80% in the first decades of the 20th century to single-digit numbers in the last period (Table 1 and   We selected nine villages in southern Transylvania which are recognized for preserving traditional Saxon cultural values and in which Saxon communities are still present.

Research Methods
The methods combined qualitative and quantitative techniques. Information collected by conducting (i) structured and semi-structured interviews was analyzed using (ii) a statistical approach. Despite the limitations of the quantitative interpretation of qualitative data, such as the lack and inconsistency within the collected data [46], subjectivism and memory blind spots of interviewed subjects, the semi-structured interview remains a valid and realistic instrument [47]. . A total of 74 interviews were conducted in the ten villages selected, with numbers per village ranging from 4 to 14 inhabitants. The interviews lasted on average 40 min and took place in various locations, including interviewee residences. All interviewees were of Saxon ethnicity, ranging in age from 45 to 93, as we preferred to interview people over 45 years of age who had lived in their native community their entire lives. Out of 74 interviewed persons, 66 were permanent residents, and eight had emigrated to Germany and were temporarily visiting their native village.
The interview consisted of a set of eight questions to determine how Saxon people perceive the resilience of their cultural landscape and their tangible and intangible heritage. The first question Q1-"How long have you been living here?" had an introductive character and referred to the responder's personal relationship with the community. The questions Q2-Q8 (questionnaire included in the Supplementary Material) addressed the interviewees' perception on the following topics: focused on the potential to revitalize traditional activities, addressing both the involvement of the interviewee and the local authorities.
Based on the answers, we compiled lists of features of tangible and intangible heritage mentioned, their recent changes and the driving forces said to be responsible for these changes. Synthesizing Sustainability 2019, 11, 3102 6 of 18 information regarding the continuity or disappearance of features of Saxon culture (Q3-Q5) with the specific changes and threats (Q6, Q7) and the community response to them (Q8), provided qualitative data on the resilience of heritage.
(ii) Statistical approach. First, groups were formed based on similarities and differences between responses [19,48]. We used hierarchical clustering to form groups of features of the cultural landscape and intangible heritage, considering their resilience towards the driving forces mentioned. Clusters were chosen based on a dendrogram, which allowed the distinction of three types of resilience, here referred to as high, low and no resilience.
Second, we performed a canonical correspondence analysis (CCA). Although frequently used by ecologists [49], this type of multi-variate statistics has recently penetrated sociological analysis [50,51]. The aim of the CCA is to establish how a group of variables (explanatory variables) determines the variation of another group of variables (response variables). Both groups of variables are assumed to be qualitative in nature and are coded with the values one and zero. In this study, the driving forces were the explanatory variables, while the response variables were the importance of features of tangible and intangible heritage. For each interviewee, we revised the list of driving forces and coded them as perceived by the respondent. Each driving force mentioned in the answer received the code 1 (present), while driving forces not mentioned received the code 0 (absent). The same rule applied for coding the importance of features of tangible and intangible heritage. To test potential differences in the attitudes of different age classes, the interviewees (n = 74) were divided into two categories: STK1 representing local people ranging in age from 65 to 93 (n = 53), and STK2 representing local people from 45 to 64 (n = 21). STK1 differs through vast life experience in the local environment that was essentially shaped by the Second World War and by the communist reforms of society, culture, economics, and politics. The professional profile of STK1 also differs greatly from STK2, as these interviewees had contributed to the perpetuation of many agrarian practices. Additionally, they had a deep attachment to religious practices. STK1 formed the majority within their communities and are characterized by a strong social cohesion. The individuals from the smaller STK2 group experienced a rather shorter period of time in connection with the traditional lifestyle. Dividing the interviewees into these two groups allowed analyzing separately people who were born and lived in a period when the Saxons were actively involved in preserving, maintaining and continuing to shape landscape features (STK1) and those who were born and lived in the communist period (STK2). The CCA enabled the assessment of whether these two groups differ regarding their perception of how and why heritage features have changed. Statistical analysis was carried out in R version 3.1.2, using the package Vegan for cluster analysis. The R function rect.hclust was used to visualize the cutting and the function cutree to make a classification vector with a certain number of classes [52]. The function cca was used for CCA.

Outcomes of the Interviews.
Based on the interviews, we identified 25 features considered relevant for Saxon heritage (V1 to V25 in Table 2). The features referred both to elements of the cultural landscape (such as fortified Saxon churches) and to intangible heritage (such as cultural/recreational events). Responses to Q3-Q5 revealed that eleven of the 25 features mentioned have completely disappeared and two are in the process of disappearing. Together these represent 52% of all features. Of the twelve remaining features, three (12%) continue in their traditional state ( Table 2). They belong both to the tangible heritage (e.g., old Saxon houses with heritage value, fortified Saxon churches) and the intangible heritage (e.g., religious mass). Nine features (36%) continue with some changes, most of them belonging to intangible heritage (e.g., culinary recipes, religious ceremonies, the Saxon dialect). Overall, 12% of the features determined were of high resilience, and 36% were of low resilience.
The analysis of the answers to Q6, revealed major differences between the traditional way of life once practiced in the village and the present way of life. We identified changes in relation to traditional land use (Table 3a), traditional activities (Table 3b), and socio-cultural capital (Table 3c).
Nine driving forces, related to demographic, political, economic, historical, and external factors were determined (Table 4). Six driving forces (DFN1-DFN6) were perceived by local people to negatively affect features of heritage that they greatly value. Three driving forces (DFP7-DFP9) were considered as positive factors for maintaining local traditional values. An important finding from the interviews was that the main factor responsible for the transformations of the traditional Saxon landscape was the migration of the Saxons at the end of the Cold War. Interviewees linked the Saxon migration to changes in the traditional activities related to the identity, authenticity, and integrity of the traditional structure of the cultural landscape (Q7). The present population no longer practices fruit farming and no longer processes the fruit to obtain juice and apple wine The Saxons practiced agriculture and supported a production society The present population no longer practices agriculture in the tertiary and secondary sector and becomes a consumer society (b) Traditional Activities.

Statistical Approach
Based on the results of the hierarchical clustering (Figure 3), the cultural features were assigned to one of the three types of resilience determined, i.e., high, low and no resilience (Rhigh, Rlow, and Rloss), respectively ( Table 2).

Based on the results of the hierarchical clustering (Figure 3), the cultural features were assigned to one of the three types of resilience determined, i.e., high, low and no resilience (Rhigh, Rlow, and Rloss), respectively ( Table 2). The CCA analysis was used to refine the clustering and gain an improved understanding of the relationship between driving forces and features of heritage as perceived by the interviewees. It was thus possible to determine the driving forces that contributed the most to the preservation or change of the values and to analyze potential related differences between the age groups STK1 and STK2. The outcomes of the CCA are represented in Figure 4 as a triplot, showing the projections of the observations (corresponding to the answers of respondents), the heritage values (represented as points) and the driving forces (explanatory variables, represented as arrows). Overall, of the 25 values identified, four were mentioned by both groups, 16 were mentioned only by respondents from STK1, showing a greater connection to Saxon heritage compared with STK2, who only identified five unique features (Table 5). To test that the statistical significance of the CCA analysis was not random [53], permutation tests were performed (999 permutations, alpha = 0.05) [51]. The variables that significantly contribute to understanding the resilience of the landscape are highlighted: DFN1 (with a weight of 0.98), DFN4 (weight 0.86), DFP7 (weight 0.56), and DFP9 (weight 0.54). These driving forces (see also Table 4) are mainly related to the demographic factor (DFN1-Saxon migration and DFP7-group cohesion), but also to economic (DFN4-evolution of the technique) and political factors (DFP9-uncertain property rights). We conclude that the answers of the local people in the first category (STK1) were mostly related to variables which explained factors that led to the loss, preservation or modification of heritage features.

Loss and Preservation of Saxon Heritage
Following eight centuries of presence [39,54] and cohabitation in Transylvania [33], the resulting distinct Saxon cultural landscape fulfills the criteria of a traditional, historical landscape, co-evolved with a specific Saxon heritage [42]. The spiritual, symbolic (intangible) and tangible features identified in this study show great variability regarding their ability to persist, as 12% showed high resilience, 36% showed low resilience and 52% have already disappeared.
Moreover, our multivariate analysis showed that the Saxons are very attached to both features of tangible and intangible heritage and appreciate them in various ways. This was especially the case for the older age group assessed (STK1), who contributed to the shaping and maintenance of Saxon heritage and cultural landscapes through, e.g., agricultural practices. The younger generation group (STK2) was less aware of what had been lost or kept and mentioned much fewer specific features of tangible and intangible heritage (Table 5), nevertheless, they wish to keep these values for future generations.

High Resilience
Features of intangible heritage which have perpetuated in their traditional state are only to be found in the context of the religious tradition of Sunday mass. This continuity is fostered by the fact that the Church as an institution values tradition very highly [31], as the content and choreography of religious rituals continue in their original forms, and the penetration of modern influences is restricted. Sunday mass is, therefore, the most well-preserved tradition, which goes in parallel to the important role of the church in the management, administration, and education of the Saxons as an ethnic group. This effect is particularly pronounced in the Mălăncrav village, whose intangible heritage showed a high resilience. The community has been served by the same evangelical priest (originating from Germany) since 1991. The village is characterized by its remote locality, a relatively low and late migration of the Saxons, the existence of a young population and high group cohesion within the Saxon community. These aspects correspond well with the preconditions for the persistence of cultural landscapes in Europe as determined by [25]-and we might add that they also seem to be important for explaining the high resilience of intangible heritage.
Tangible heritage. Saxons left visible marks on the landscape (Figures 5 and 6) through fortified citadels and churches and the architecture of the houses they built [33,55]. Fortified citadels and churches are historical monuments with a high cultural value [56,57] which deserve and receive preservation and protection measures [58] and thus have persisted. The fortified churches in southern Transylvania [59], including those of the analyzed villages Prejmer, Hărman, Biertan, Mălăncrav, and Vulcan, are very well preserved, unlike the one in Sânpetru, which needs extensive restoration work. The overall good condition of these churches illustrates well the interconnectedness of tangible and intangible heritage, i.e., religious practices. It is very likely that the Evangelic church, through its role in the spiritual life of the communities, contributed to the resilience not only of the intangible, but also and the tangible heritage and, consequently, the Christian beliefs and values contributed to the protection of the material patrimony of the Saxons. Today, a range of other values, such as memorial, historic, scientific, and architectural, become increasingly important for the preservation of the fortress-type churches.
The houses built in the Saxon architectural style and the traditional gates have most likely persisted due to their highly durable building materials (rocks, sand, and lime), specific construction techniques, the resistance of the buildings to earthquakes, their aesthetics and the registration of these houses on the list of historical monuments. Paradoxically, the element that contributed to the persistence of these buildings in their present form, especially in the communist period, was uncertain property rights-a factor highlighted in the CCA. These Saxon houses were nationalized and subsequently rented for decades, because the state did not have the right to sell the houses. As the tenants did not own the houses, they did not renovate the houses but maintained their integrity while awaiting the resolution of the legal status of these buildings. Their rightful owners were Saxons who had emigrated to Germany or East Germany before 1989. After the fall of communism in 1990 [2], they started to return to their villages and to claim their houses again. During the decades of uncertainty regarding the property rights, the Saxon houses remained relatively intact. Moreover, local people started to appreciate the patrimonial value of these houses, and they gradually became the symbol of the local communities. The local authorities in several communities (Prejemer, Hărman, Vulcan, Biertan, Cârţa, and Mălăncrav) have established General Urban Plans [60] enforcing the maintenance of intact facades of Saxon houses by their owners. Another factor contributing to the continuity of the tangible heritage in the old centers of Saxon villages was their inclusion in the buffer area of sites classified on the UNESCO world heritage list, such as Strada Mare and the Fortified Citadel and Church in Prejmer. The status of the UNESCO protected the site of the Fortified Church of Prejmer [59,[61][62][63] forced the local authorities in Prejmer to apply the management plan, with which the identity, authenticity, and integrity of the houses in the buffer area, in this case of those on Strada Mare, are preserved. The tourist attraction of the Saxon heritage contributed in equally to the preservation and persistence of the Saxon houses. Outside the perimeter of the UNESCO sites, prominent examples of the persistence of tangible heritage can also be found, for example in Hărman, where the authenticity and historical identity of the historical center and the Fortified Evangelical Church are very well preserved.

Low Resilience
Traditional activities. We determined nine elements of Saxon intangible heritage, which persist with some modern influences. (i) The Saxon dialect is currently spoken by very few Saxons, most of whom are old; the few young people who come from mixed families declare themselves to be of Saxon ethnicity but no longer speak the dialect. As Mr. H.G. of Harman stated, "the Saxon dialect needed about 300 years to form and spread in the Saxon communities in Transylvania and very little to disappear". (ii) The number of subscribers to Saxon publications in German is decreasing in parallel with the Saxon speaking population. (iii) The Fashing Festival in Prejmer is a Saxon tradition which continues to date thanks to the involvement of the local authorities and the Saxon communities. As recounted by Mr. W.T. of Prejmer, this festival is organized in February each year by the Saxons and consists of a parade on the village roads of horse-drawn carriages equipped with stoves on which pancakes are cooked. The carriages go from door to door and receive products from the citizens, such as eggs, flour, milk, sugar, and oil, and give pancakes in exchange. Overall, the importance of (iv) culinary recipes declined. (v) The cult of the dead and (vi) the Christmas/Easter ceremonies have a reduced resilience, mainly because of the loss of other intangible traditional aspects, such as fanfares, choirs, and pipe organs in the churches. (vii) The christening of young people and youth confirmation festivities continue with influences related to ethnicity, age, and time of officiating this religious ceremony. Regarding (viii) Crops and (ix) animal rearing, many changes occurred due to the spreading of new agricultural technologies, related to mechanization and motorization of agriculture. Additionally, after the fall of communism, subsistence agriculture became unprofitable, and livestock numbers and grassland areas have declined noticeably as in many areas throughout Eastern Europe [64].

Loss of Tangible and Intangible Heritage
Thirteen mostly intangible heritage features are no longer continued. For instance, the fanfare, an instrumental group that appears in religious ceremonies and plays, for example, traditional funeral music. The original two to three fanfares per village, are reduced today to only one semi-professional group, and the original repertoire changed. We additionally observe a decline in a series of traditional feminine activities (crafts, sewing of traditional clothes) as well as traditional masculine occupations (house construction techniques, the local manufacturing of bricks, manufacturing carts and cartwheels, ironwork, shoeing horses, masonry, and carpentry). The decline of these activities is due to social dynamics, technological developments, as well as to the before mentioned decline in Saxon population.
All the interviewed persons expressed feelings of great nostalgia for the past social climate. Due to the emigration of Saxons, villages lost part of their multicultural and multi-ethnic diversity and traditional identity. The interviewees display a strong feeling of nostalgia with regard to what Saxon villages used to represent, while also acknowledging a sense of concern regarding the preservation of heritage.

Fostering Resilience of the Saxon Tangible and Intangible Heritage
In a recent publication [7] present a framework for strategies to foster resilience-aspects of which can also be observed in the study region, as, e.g., by interviewees who are actively involved in the revitalization of the Saxon community's social and cultural life. Mrs. U.C. stated "I am a professional musician and I get involved only in the cultural activities of the Saxon community. I organize shows with the children in the church, I accompany them with the piano, I play the organ every Sunday during the religious mass, in terms of gastronomy I have kept some recipes from my mother, I make cakes, jams, jelly". Mrs. E. mentioned organizing Harvest Day and staging artistic shows for Christmas and Easter. A private entrepreneur of Swiss origin opened an organ repair workshop in Haman ten years ago because of the high numbers of repair-related requests-a consequence of all Saxon evangelist churches being very old, with old organs requiring repair.
Population decline poses a great threat to heritage preservation. Among the villages studied, the Saxon population amounts to an average of 64 inhabitants, corresponding to 2.7% of the respective total population ( Table 1). The demographic decrease of Saxons threatens the continuation of the evangelical cult, as its practices have become increasingly difficult. Thus, despite financial support from the diaspora (former members of the community who now live abroad) the declining number of community members is threatening the continuation of local traditions.
An important development supporting the preservation of the built tangible heritage is their inclusion on the historical monuments list [65]. The rural site Biertan has the protected status from UNESCO, being the first Romanian site included on the World Heritage List. The local authorities have managed to preserve the architectural integrity and authenticity for several streets of the village. Similarly, the nomination of the fortified citadel and church in Prejmer on the UNESCO World Heritage List encouraged the local authorities to preserve the buildings in the old center of the village. Overall, the UNESCO international protection status of the rural sites Biertan and Prejmer is a core element to increase heritage's resilience.

Conclusions
The Saxon cultural landscape was and still is vulnerable to historical and socio-economic changes. The results of interviews indicate a high persistence of tangible heritage in the cultural landscape, such as churches, citadels, and traditional houses, which are well preserved and can, therefore, persist for a long time. However, more than half of the heritage features mentioned by local people were reported to have disappeared, most of which were intangible forms of heritage. This loss is partly explained by the fact that they could not be passed on further, due to population decline. Therefore, the main factor responsible for changes in the Saxon cultural landscape was the mass emigration of the Saxons, driven by political and economic factors. Long term persistence of the remaining tangible and intangible Saxon heritage relies on the Saxon people who remain in the area and are willing to maintain and revitalize specific heritage features.
As stated in the introduction, landscape researchers tend to reduce the diversity of tangible heritage to physical aspects of cultural landscapes, and intangible heritage to land use practices which have a direct and visible impact on the landscape. Broadening the analysis to include additional forms of heritage is challenging but rewarding. We consider that by applying a more comprehensive view of people, landscape and heritage, it is possible to develop novel ways of (I) increasing the understanding of the role and relevance of the local landscape for local stakeholders, (II) engaging the local population in conservation measures, (III) jointly developing concepts for preserving and further developing various dimensions of cultural heritage and (IV) potentially increasing the resilience of socio-ecological systems under current scenarios of global change.
In the case study presented, we deliberately did not ask for specific landscape-related features but allowed respondents to choose what they considered a part of their heritage. In our view such a list of features, enriched with information regarding resilience and related driving forces, opens up the arena for community-based processes, e.g., using a joint learning circle procedure [66]. Our methods could be further developed by building specific direct and indirect links between the features assessed and the cultural landscape, in order to more fully understand dynamics in the past, drivers of change [67], and vulnerability and development potential for the future [68].
