Landscape Perception and Public Participation for the Conservation and Valorization of Cultural Landscapes: The Case of the Cinque Terre and Porto Venere UNESCO Site

: Europe retains a great variety of cultural landscapes that constitute a signiﬁcant part of the European cultural heritage. In the last decades, these high-quality landscapes are facing several challenges due to socio-economic transformations that often compromise their integrity. This situation is even worse for terraced landscapes, as in the case of the Porto Venere and Cinque Terre UNESCO World Heritage List site. The Management Plan developed for this area needs to deal with different issues: abandonment of terraced cultivations and growth of secondary forests, hydrogeological risk and high touristic pressure. Public participation is increasingly important in the process of decision-making, for incorporating the ideas and the needs of the local communities, helping to ﬁnd effective solutions for the valorization of historic landscapes and for improving the quality of life. This research has investigated the perception of the local community regarding the current landscape dynamics and other critical issues studying the opinions of two social groups: farmers and residents. The purpose was to identify the best management strategies for the Management Plan and to actively involve the population in the decisions. The involvement of the local community turned out to be a very effective tool for the development of the Management Plan, suggesting a focus on the conservation of dry-stone terraces and the reduction of reforestation processes, as the strongest perceived threat is the abandonment of cultivated terraces and the resulting risk of landslides. The methodology applied in this study can be reproduced in other cultural landscapes characterized by high quality, complexity and fragility, while an active involvement of the population turned out to be important also for increasing the feeling that institutions take care of its issues.


Introduction
Europe, and in particular Mediterranean countries, retains a great variety of historical rural landscapes, due to the millenary human presence that has shaped the territory with agro-pastoral activities [1,2]. Nowadays, historical rural landscapes represent a significant part of the European cultural heritage [3]. In Europe, the traditional landscapes remained almost unchanged until the early twentieth century, when the great socio-economic changes that affected the entire continent led to major consequences for the rural world and its landscape [4][5][6][7][8].
Many cultural landscapes still have high qualities (in terms of environmental services, tourism attractiveness, high-quality food production, biodiversity, cultural and historical value), but in recent years, it is increasingly urgent to find solutions for their maintenance, in the perspective of sustainable development, both from an environmental and an economic point of view [9]. This situation is even more common for terraced landscapes, whose presence is widespread in Southern Europe. Despite their historical and aesthetic it can contribute to verify the relationship between scientific research and the views and needs of the population [25][26][27]. The potential and suitability of involving local people in landscape management and planning is explicitly expressed in the Convention on Biodiversity [28], the European Landscape Convention [18] and the Aarhus convention [29]. Moreover, it is known that it is not possible to sustain the "intimate interaction between communities and land" by government intervention alone [30], without involving the local communities [31]. In fact, the people who inhabit a place have important perceptions and attitudes about planning issues and integrating social and perceptual information could improve the understanding of the impact of landscapes changes on the people who inhabit them [32]. Perception and aesthetic appreciation of a landscape depend on many factors, some of which are common to everyone and are stable in time and space. Other factors are determined by the social context in which a person lives. The perception of the landscape may be modified over time with changes to the territorial system, landscape and society that produced it. Both rural and urban landscapes have always been subjected to drastic transformations because "they are the expression of the dynamic interaction between natural and cultural forces in the environment" [3].
The goal of this research is to evaluate landscape perception and public participation for the drafting of a UNESCO site Management Plan, collecting data on the main issues and needs of the local community. This was done by analyzing the opinions of two social groups: farmers, who, through their work, conserve the cultural landscape, and residents and workers within the UNESCO site, who benefit daily from this territory. The purpose was to obtain information to support the strategies of the Management Plan, taking into account the real needs of an area with specific issues: crop abandonment, hydrogeological risk and management of tourism. In fact, this unique cultural landscape can be preserved only by actively involving those who still cultivate the land, with the support of the institutions and of the rest of the resident population, in order to try to apply a sustainable management model. Moreover, this methodology can be reproduced in other UNESCO sites' Management Plans. In fact, while public participation and the involvement of the local communities are recognized as fundamental for landscape and territorial planning, their use in addressing the UNESCO sites' Management Plans is not so widespread.

The Study Area
The UNESCO Site "Porto Venere, Cinque Terre and Islands" extends for about 4700 ha in the Region of Liguria, in northern Italy ( Figure 1). It comprises a very steep coastline where the human communities have adapted themselves to this rough and inhospitable territory by building settlements and by cultivating land and creating a unique and remarkable cultural landscape. Since the 12th century, the work of farmers has transformed the slopes into an intensively terraced landscape in order to make it suitable for agricultural activities, mainly for cultivating vines and olive trees [33,34]. Terranova [35] reported, for the Cinque Terre region, densities of 3300-6000 m of dry-stone walls per hectare, with a total length of the walls equal to about 6700 km. The area is characterized by Mediterranean climate, with warm winters and hot summers with frequent periods of drought. The average annual rainfall is equal to 1343 mm, with maximum peaks in autumn and spring. The mountain range runs parallel to the coast and despite the limited altitudes, due to the short distance from the sea, it causes a pronounced steepness of the whole territory. The hydrographic network consists of small streams, which frequently cause hydrogeological problems, such as erosion and landslides. The territory of Cinque Terre and Porto Venere has been inscribed into the UNESCO WHL according to criteria (ii), (iv) and (v), with the motivation that it embodies "a cultural site of outstanding value, representing the harmonious interaction between people and nature to produce a landscape of exceptional scenic quality that illustrates a traditional way of life that has existed for a thousand years and continues to play an important socioeconomic role in the life of the community" [36]. Thus, the reason for the inscription of this territory in the UNESCO WHL has to be found in the unique landscape, made of drystone terraces on steep slopes, built by men over the centuries [16]. Nowadays, terraces allow the cultivation of vines, olive trees, citrus trees and vegetables. Vineyards are the most widespread cultivation, carried out using the traditional pergola bassa technique, with the branches of the vines that grow on a pergola 80-130 cm high [37].
Since the end of World War 2 (WWII), this territory has undergone many socio-economic as well as environmental and land use changes that are currently threatening the historical landscape of terraced cultivations. The causes, threats, pressures and driving forces are manifold but can be summarized in a few key points to provide a complete framework to the readers: • Socio-economic situation: As in the majority of rural and marginal areas of Italy, Cinque Terre and Porto Venere also suffered from a significant depopulation. In the period 1931-2011, the depopulation in the municipalities touched by the UNESCO site (Porto Venere, Riomaggiore, Vernazza, Monterosso al Mare, Levanto) was equal to −34.5%. • Crisis of agriculture: Statistics on agriculture for this territory highlight the crisis of this sector, at least from the beginning of the twentieth century. As it has happened in many European rural landscapes, the management regime these activities developed under is no longer economically feasible [9]. In the territory of the municipalities interested by the UNESCO site, there has been a decrease in the number of farms equal to −76% in the period 1929-2010, and a decrease of the Utilized Agricultural Surface (SAU) equal to −46% in the period 1971-2010. Since 1929, the two main cultivations (vines and olive The territory of Cinque Terre and Porto Venere has been inscribed into the UNESCO WHL according to criteria (ii), (iv) and (v), with the motivation that it embodies "a cultural site of outstanding value, representing the harmonious interaction between people and nature to produce a landscape of exceptional scenic quality that illustrates a traditional way of life that has existed for a thousand years and continues to play an important socioeconomic role in the life of the community" [36].

Since 1929, the two main cultivations (vines and olive trees) began to suffer a strong decrease, with a reduction in their surfaces respectively equal to −85% and −75% [38,39]. Among the main causes of the decline of the local agricultural sector are: the difficulties inherent in practicing agriculture on terraces, since among the agricultural areas, terraced slopes are often the first to be abandoned due to accessibility and economic limitations [11], the fragmentation of the properties, since 61.6% of the farms are smaller than 2 hectares, the high average age, with 36% of the farms managed by persons aged over 75 years and only 3.8% led by people 35 years or younger [38], and the low level of technology in the management of the farms. • Spread of woodlands: The abandonment of agricultural activities caused the increase of woodlands and shrubland from 55% to 77% of the territory in the period 1973-2010. The increase in wooded areas and the resulting simplification of the landscape led to a decrease in biodiversity, as landscapes rich in biocultural diversity are often those resulting from small-scale farmers and traditional practices and with a complex landscape structure [40], that can provide a variety of environments and microhabitats. Forest increase is not only the result of the socioeconomic change but also of the environmental thinking and protection strategies, applied by managing authorities, favoring the re-naturalization of the territory [41,42].

•
Hydrogeological risk: The main consequence of the abandonment of the terraces and spread of newly established woodlands is the landslides and erosion increase. As a matter of fact, the role of managed terraces in slope stability is reported for multiple environments, as well as the effects of abandonment on marginal areas [43][44][45][46][47][48][49]. Abandonment of terraces is often followed by slope colonization by pioneer species, terrace degradation, hydrogeological hazards and diffuse slope instability phenomena [50][51][52][53]. In the Cinque Terre, as well, recent landslides are directly related to the abandonment of the terraces, due to the fact that the area is characterized by a high slope gradient. A study on the detachments of the landslides after the floods of October 2011 highlighted that 45% of detachments occurred in areas occupied by forests or shrublands, 47% occurred in recently abandoned terraces and only 6% on cultivated terraces [50]. • Tourism: Historical cultural landscapes are an important factor of attraction for rural areas, where rural tourism often represents an alternative and economic diversification that guarantees a higher income for the local population than the traditional agricultural activities [54][55][56]. Tourism, however, can also be a negative element. The territory of the UNESCO site, due to its widespread reputation, has become in recent years one of the main Italian tourist destinations. This has led to the presence of a large number of tourists in a small-sized and highly fragile territory, with consequent problems due to the lack of management of tourist flows, the maintenance and the crowding of the paths (too many people on small unpaved paths can cause soil compaction and consequent increase of erosion and runoff after the rain) and the fact that tourism-related activities are replacing agriculture as the main income. In fact, in the municipalities included in the UNESCO site, 33% of economic activities are accommodation and restaurant activities and 22% are trade-related [57], confirming the central role of the tourism industry. • Territorial Planning: Besides being a UNESCO Site, this territory is marked by the presence of the Cinque Terre National Park, the Regional Natural Park of Porto Venere, five Sites of Community Importance (SCI), different municipalities, a Province and a Region. There is, therefore, the need for a better coordination between the different levels of territorial planning, to face the various challenges in a coherent way.
All such pressures, driving forces and different characteristics, led to a high degree of complexity for this fragile territory, with the consequence that planners and managers have to deal with a wide range of issues (economic, social, environmental, etc.) for providing a sustainable future, as often happens for traditional cultural landscapes [9].
Although the overall situation may seem rather negative, there are recent initiatives with a positive impact. The spread of organic farming, the agricultural cooperatives, the use of rural development funds for the restoration of dry-stone walls and for monorails, can all contribute to increase once again the surface used for traditional crops. Moreover, in the last few years, a number of young people have decided to restore the terraces that belonged to their families and to cultivate them again. These efforts show a will of the population to face the issues and take care of the territory. Such initiatives are well worthy of attention and must be taken into account by the institutions.

The Methodology and the Use of Questionnaires
The methodology applied to investigate the landscape perception and to identify the main needs and threats has been based on questionnaires. The use of questionnaires in landscape perception studies has been attested since the 1980s, especially for research on static aspects and qualities of the landscape [58][59][60][61][62]. Questionnaires can be used directly in the field or at distance through computer-based surveys according to the sample to be surveyed and with different methodologies regarding data elaboration, correlation with spatial analysis, construction of the questionnaires and aim of the study [63][64][65][66]. More recently, the use of pictures, photomonatages or virtual images has spread to assess public preferences or the relation between landscape perception and ecological health and/or fitness [67][68][69][70].
In our survey, two types of questionnaires have been distributed, to be filled in anonymously: Questionnaire A for residents and workers (Appendix A), and Questionnaire B for farmers (Appendix B). The questionnaires were structured so as to obtain information that can be easily statistically processed, that would provide answers about the perception of the local landscape and its features, the main problems of the area and the role of public bodies in land management. At the beginning of the questionnaire, a brief introduction was added containing the motivations of the inscription of the site in the UNESCO WHL, the reason for the survey and the list of participants in the workgroup for the drafting of the UNESCO Site Management Plan.
The questionnaires were structured into four different parts, as follows. The first part has been set to collect personal information, including age, gender, education level, municipality of residence and occupation.
The second part dealt with the issues of landscape perception, with questions about the biggest changes perceived, the role of the woodland, the various landscape features and the role of agriculture. In the same part of the questionnaire, a photomontage has been inserted to investigate the perception in order to identify characteristics of the local landscape and the relationship between forest and agriculture. An actual picture of the terraced coast cultivated with the pergola bassa technique has been modified by increasing or reducing the presence of the forest in favor of vines, in order to simulate more cultivated or more abandoned/seminatural scenarios.
The third part focused on the role of the Parks, on the main threats as perceived by residents and farmers and on possible economic investments in order to minimize the critical issues and preserve the cultural landscape of terraces.
A fourth part has been added in the questionnaire tailored to farmers to investigate specific farming-related issues. The questions focused on the multi-functionality of the farm, on services for tourists offered by the farm, on the provenance of tourists, on farm characteristics (products, type of viticulture, marketing and certification of the products), on projects funded by the Rural Development Programs and on the issues and the possible solutions to improve the quality of life of the farmers.
Questionnaires to residents were distributed during different days, in different parts of the territory included in the UNESCO site, simply asking people if they wanted to participate in the survey. Questionnaires for farmers were distributed with the help of the local Cinque Terre Cooperative, and as a result, almost all the local farmers have answered the questions.

Results
Below are the main results of the questionnaires, highlighting the significant differences between the perception and expectations of residents and producers. An interesting fact comes from the difficulty of obtaining information from residents in the first phase of the survey. In fact, at the beginning, many residents refused to answer the questionnaires, complaining about the lack of attention from local institutions towards their needs, but after having explained to them the purpose of the survey also through some meetings with the population organized in the framework of a bigger participative process for the Management Plan, they started sharing their opinions and experiences. The total number of respondents is equal to 212 residents and workers and 120 farmers. The results are divided into: The role of the institutions and expectations for the future • Farms' characteristics, multifunctionality of agriculture and tourism (only for farmers)

Socio-Cultural Characteristics of the Respondents
Age and gender: The characteristics of the people who answered the questionnaire, regarding gender, age groups and distribution in the municipalities included in the UNESCO site, are representative of the local social situation. Regarding the farmers, 49% of them are over 60 years old, but a good percentage (26%) are under 45, highlighting an interesting generational turnover.
Level of education: 55% of the residents and workers completed high school and 27% are university graduates. Overall, the sample has a medium-high level of education, therefore we expected a fairly high sensitivity toward the themes of landscape protection and a considerable awareness of the respondents about living in a high-value territory. The average level of education of farmers is lower (32% completed high school and 6% have a university degree). This is mainly due to the low level of education that characterized the rural territories of Italy until the middle of the twentieth century.
Professional occupation of residents and workers: Among the residents, three main categories can be identified: traders (17%), employees of accommodation facilities or restaurants (11%) and managers of accommodation facilities or restaurants (12%). Altogether, these categories represent 40% of the respondents, excluding students (6%) and retirees (17%). It emerged that most of residents are employed in the tourism and trade industries. The level of unemployment in the sample was very low.

Landscape Perception
Identification of the most significant landscape change in recent years: For both groups, the most significant change perceived is the abandonment of the territory and of the cultivations. This answer was chosen by 53% of residents and workers, and by 93% of farmers. Residents also reported an increase in landslides (22%) among the main problems, while the spread of the woodland was chosen as the main problem by 7% of the residents and 5% of the farmers.
Importance of the different landscape features: The perception of the role of the forest within the UNESCO site is one of the main elements of difference between residents and farmers: 63% of surveyed residents consider the woods a fundamental feature of this landscape, compared with 9% of farmers ( Figure 2). To verify the importance of the main land uses, the respondents were asked to assign a score from 1 to 5 based on the importance of the different features ( Figure 3). The value attributed by residents and workers to the different landscape features are on average high, the only low score is related to pastures, a land use that disappeared from the territory many years ago, and of which remains almost no trace in the memory of the population.
The value attributed to terraced vineyards and terraced olive groves are the highest for both groups, and the importance given by farmers to vineyards and vegetable gardens is higher compared to the perception of the residents. Further interesting data concerns the scores given to woodlands and shrublands. These values show that residents have a propensity to perceive the overall environment around them as important, not only the man-built landscape but also the seminatural and spontaneous one.
Although the values assigned by farmers are lower and despite the fact that they do not perceive the woodland as a fundamental feature of the surrounding landscape, the deciduous forests received high scores on average. To verify the importance of the main land uses, the respondents were asked to assign a score from 1 to 5 based on the importance of the different features ( Figure 3).

The photomontages: To further reinforce the perception of the cultural landscape, the abandonment of crops and the increase of the forest, a photomontage of a terraced slope was prepared. The intermediate level (photo B) is a real photo of a slope with traditional terraced vineyards and with some woods. Then, two other scenarios have been realized increasing the woodlands (photo C) or the terraced vineyards (photo A) (Figure 4). We asked residents and farmers to choose what kind of landscape they prefer and that best represents the place: 94% of farmers opted for the same answer, with a clear preference towards a mainly terraced and cultivated landscape (photo A), while among the residents, the preference for the same landscape is lower (78%, while 22% preferred photo B), but still predominant.

The Role of the Institutions and the Expectations for the Future
The role of the Parks: In order to understand the opinions about the role of the Parks in protecting the territory, the population were asked if they perceive a change since the National Park of Cinque Terre (1999) and the Regional Natural Park of Porto Venere (2001) were established. The awareness of residents of the presence of two parks is high, with only 1% of the sample not able to determine if they reside or work inside one of the two parks, and 65% of the respondents stated that they have perceived a change. Most of these changes, however, are seen as negative by residents. Many answered that the creation of the Parks merely resulted in increased tourism, and this is not always perceived positively. Tourism initially brought benefits to life and to local economy, but later caused a decline in the quality of life due to overcrowding and loss of basic social services (school, pharmacy, post office, etc.). The Parks are considered to excessively focus on tourism marketing, rather than investing in effectively restoring and maintaining dry-stone terraces. As far as the farmers are concerned, they have been asked to identify the main problems related to their specific activities. Excessive bureaucracy is the most frequently mentioned one (85%), followed by workforce availability (73%), damages caused by wildlife (69%), lack of awareness by the tourists of the characteristics and of fragility of the territory (68%) and the lack of adequate roads and paths (57%). Of the farmers, 67% identified the National Park as the institution that should primarily take care of land management.
Threats and expectations for the future: One of the main threats for residents is related to landslides and erosion, and the investments towards the mitigation of hydrogeological risk are considered a priority, followed by investments in the protection of the cultural landscape and agricultural activities. Natural aspects appear to be secondary to landscape and agriculture, confirming that the UNESCO site is perceived as a place of conservation of a cultural landscape heritage rather than of naturalistic features. Tourism has also been chosen as a relevant sector of intervention, not with the purpose of increasing the number of tourists, but to improve its management and change its characteristics. According to farmers, there are two main priority sectors of investments: tourism, chosen by 27%, and creation of a network of farmers, chosen by 24%. Farmers ask for public support

According to farmers, there are two main priority sectors of investments: tourism, chosen by 27%, and creation of a network of farmers, chosen by 24%. Farmers ask for public support for investment in rural hospitality and policies to implement a more sustainable tourism, based on the discovery of local products, making the farm the main reference point for the tourists. Another 21% of farmers chose the theme of nature, particularly with regard to wildlife management, since it is perceived as a relevant problem due to the damages caused by wildlife and the costs of fencing off agricultural areas. The theme of the hydrogeological risk was chosen by 17%, because they consider that the costs of management and maintenance of the dry-stone terraces cannot fall entirely on farmers, since the entire community takes advantage of it.

Farms Characteristics, Multifunctionality of Agriculture and Tourism (Farmers' Questionnaires Only)
Characteristics of the farms: Agriculture is the main activity for only 13% of farmers, suggesting that the agricultural economic system, as it is currently organized, is not viable enough to ensure a fair income for farmers. The surveyed farms have an average size of about 1.5 ha, with only four properties that exceed 5 hectares ( Figure 5): 80% of the farmers deliver their grapes to the wine cooperative, so only a minority of the respondents produce wine directly from the farm. Despite the small size of the properties, 82% of respondents stated that they own uncultivated plots, highlighting how abandonment also involves active farms, mainly because of the difficulty to access some fields, or for the high costs of putting terraces back into production that have been left uncultivated for years, on which trees and shrubs have grown. A lack of cooperation between farmers is also noticeable: about 90% of them work individually without collaboration with other farmers. Cooperation, especially for sharing equipment or for common agricultural operations, although viewed positively by the farmers themselves, is uncommon. for investment in rural hospitality and policies to implement a more sustainable tourism, based on the discovery of local products, making the farm the main reference point for the tourists.

Characteristics of the agricultural productions: Despite the great importance of agricultural activities for the maintenance of a unique cultural landscape and the high quality of the local products, the local agricultural sector is very small in terms of workforce involved and quantity of goods produced. Farmers were asked about the chosen method of cultivation, to see if they are taking advantage of the opportunities given by an evolving market which is increasingly oriented towards high-quality and sustainable produce, with consumers willing to spend more in exchange for better quality.

Farmers were asked about the chosen method of cultivation, to see if they are taking advantage of the opportunities given by an evolving market which is increasingly oriented towards high-quality and sustainable produce, with consumers willing to spend more in exchange for better quality. Many farms are conducted with conventional methods (40%), but despite the difficulties of a conversion to more natural methods due to vines' pathogens, almost 47% of farmers opted for the Integrated Pest Management (IPM) and 12% for organic farming (Figure 6a). The quality of the products is ensured by the DOP (Protected Designation of Origin) and DOC (Controlled Designation of Origin) certifications that help with market positioning. The main products are related to wine (mainly Cinque Terre DOC and Sciacchetrà DOC) and DOP olive oil, but there are also other popular products (citrus fruits, honey, vegetables). Most farms (72%) have concentrated their production only on one product. This choice creates a greater vulnerability because it is subject to market fluctuations, to adverse climatic conditions or to pathogens, but is explained by the small average size of farms and by the fact that farming is the main activity of only 13% of respondents. Of the sample, 15% have differentiated production with at least two products, and only a small percentage of farmers achieve a very high degree of differentiation in production (Figure 6b).

The main products are related to wine (mainly Cinque Terre DOC and Sciacchetrà DOC) and DOP olive oil, but there are also other popular products (citrus fruits, honey, vegetables). Most farms (72%) have concentrated their production only on one product. This choice creates a greater vulnerability because it is subject to market fluctuations, to adverse climatic conditions or to pathogens, but is explained by the small average size of farms and by the fact that farming is the main activity of only 13% of respondents. Of the sample, 15% have differentiated production with at least two products, and only a small percentage of farmers achieve a very high degree of differentiation in production (Figure 6b). Vines' cultivation: In recent years, the cultivation of the vine is facing a significant transformation. The traditional pergola bassa technique, with the branches left to grow on a pergola made of wooden poles and steel wire, is gradually replaced by rows. Reasons for this are found in a greater ease in performing the different operations (pruning, treatments, planting, harvesting), rather than in an increase of production. The consequence is a certain negative impact on the local landscape, as modern rows are aesthetically very different from the pergola bassa and they are found in almost all the modern vineyards in Europe. Moreover, the pergola bassa completely covers the terrain, and it is therefore more effective in reducing soil erosion during heavy rains. Of the farmers, 63% continue to cultivate the vines mostly in the traditional way, while 35% have already changed the training to the row system and 2% are currently converting them.
Use of Rural Development funds: The funds of the Rural Development Plans 2007-2013 proved to be really effective as a tool for restoring and maintaining the historic landscape. Of the farmers, 94% applied to receive these funds, to be used for the restoration of dry-stone walls (90% of the applications).
Multifunctionality of farms and the role of tourism: In such a complex territory, tourism plays a central role, as already mentioned, with positive and negative consequences.

On the one hand, it increases the market for the local products, representing a chance of economic diversification for the farmers and increasing job opportunities; on the other hand, it has caused a deterioration in the quality of life of the local population, due to the excessive number of tourists and to the prevailing of mass tourism. Questionnaires show how important tourism is for farmers, and consequently for the maintenance of agricultural activities and the Cinque Terre cultural landscape. On a scale from "not important at all" to "crucially important", 84% of the sample consider tourism to be "very important" or "of crucial importance" for their own farm (Figure 7a), but it seems that this resource is not adequately exploited by the farmers themselves. In fact, 76% of farms do not offer direct services to tourists, a sign that farmers mainly rely on the tourists who buy their products from other retailers, while only 14% practice direct sale and 6% provide accommodation for tourists (Figure 7b).

Discussion
Public participation and perception are nowadays considered a priority for landscape planning decision-making, for exploring co-management options, adaptation alternatives and for integrating the knowledge processes which can guide future landscape and nature management policies [71]. Our results showed that the perception of residents and farmers is not always the same. Results also showed that there are no significant differences inside the two groups, and that socio-cultural characteristics (age, gender, level of education, etc.) of the respondents do not seem to statistically influence their opinions. This is something commonly found with other rural areas, as other studies highlighted how people actively involved in agricultural activities hold a higher body of non-scientific knowledge, called local ecological knowledge (LEK), with respect to people visiting the area or living inside the area but not directly involved in agricultural activities [72,73]. The feeling of belonging to a rural and agricultural culture is still perceived by the Cinque Terre population, but this feeling is not equally strong among all the residents, since many have lost their rural roots as they have always been working in the tourism industry. This is also confirmed by the old average age of farmers, although in recent years, a generational turnover has begun. The lower average level of education of farmers does not necessarily correspond to a low level of knowledge and awareness of the landscape, since the experience gained in the field can be much more effective.
The main difference between farmers and residents refers to the different perception of the woodlands: something thoroughly negative for almost all of the farmers, while residents perceive them partly as an important feature of the landscape and partly as a problem. However, it is possible to identify some common and crucial key points.

The main difference between farmers and residents refers to the different perception of the woodlands: something thoroughly negative for almost all of the farmers, while residents perceive them partly as an important feature of the landscape and partly as a problem. However, it is possible to identify some common and crucial key points. All the respondents identify the local landscape with the idea of "man-made environment", in which the fundamental features are represented by dry-stone terraces and cultivation of vines and olive trees; in the collective imagination of the respondents, there is a terraced and cultivated landscape, where the wood is the natural frame.
Tourism appears to be the priority area of interventions for both groups and deserves special attention for its consequences on the territory. Worldwide, the relationship between the territories included in the WHL and tourism seems controversial and not always easy to understand, since many authors report a long-standing conflict between heritage protection and tourism development [74][75][76]. On one side, world heritage sites can attract large numbers of tourists and then generate revenue and create jobs, while on the other side, they can attract excessive numbers of visitors, with the result that the latter have the potential to destroy the environmental and cultural integrity of the World Heritage Sites themselves. Generally seen as a positive factor induced by the creation of the Parks, in the last decade, tourism has caused a worsening of the quality of life for the local population. Despite all the problems related to tourism and the difficulty to make the most of the potential that it could offer for farmers (76% do not provide direct services to tourists), 60% of the farmers believe that the services offered to tourists should be increased. More than a real desire to increase tourism, the data points to a need to rethink the organization of hospitality and the services provided for this specific territory and to differentiate the types of tourism. Tourism is in fact currently concentrated in the villages, and it is a mainly daytrip tourism, so only a very small part of the revenue gets to farmers, who are the ones who maintain the territory and the landscape of the Site. As happens in other parts of the world, farmers in many rural communities have historically been able to conserve biodiversity and the territory while supporting their livelihoods [77] through the application of traditional practices, as the transmission of knowledge across generations is crucial [72].
The opinion of the farmers has been therefore very useful in addressing the Management Plan. Tourism-related strategies for the area have been addressed to increase the presence of tourists in the rural areas. This could lead to benefits for both the residents, since the overcrowding in the small villages would be reduced, and the farmers, who may increase their incomes that could be reinvested in agricultural activities. The risk, which, in part, has already become the reality, would be that the hospitality activities carried out by farmers would replace the agricultural activity if the incomes from hospitality are significantly higher.
The agricultural sector has significant weaknesses (property fragmentation, lack of cooperation between farmers, lack of services offered directly to tourists, limited direct selling of products), but it also shows some encouraging signs of a slow recovery. In fact, in recent years, there has been a slow but perceptible return by some young people to agricultural activities, together with the spread of local associations of citizens who are involved in restoring dry-stone walls, removing shrubs from abandoned terraces and turning them back into cultivated areas or promoting organic agriculture or IPM.
The strategies developed for the Management Plan intend to encourage local institutions in providing tools and expertise for supporting farmers in offering new services (guided tours to the wineries, tastings, etc.), helping them to reach out more and more to tourists interested in discovering the local products and the local rural life.
The strongest perceived threat, for both groups, is the abandonment of the terraces and the resulting risk of landslides. Despite the fact that the "spread of woodland" was not the first answer chosen, it is possible to state that, especially in the consciousness of the farmers, there is a cause-effect correlation between the abandonment of the terraces, the spread of woodland and the hydrogeological risk. The fact that hospitality activities offer lower risks and higher profits than farming is another threat to agricultural activities.
The priority sectors of investments identified through the questionnaires reflect the critical issues and the expectations perceived by residents and producers. Farmers call for a greater support from the National Park regarding the applications and the access to Rural Development Plan funds, the availability of skilled workforce for reconstruction the dry-stone walls, the streamlining of bureaucracy and less administrative procedures and permits for removing shrubs and trees on abandoned terraces, where there is a will to recover them for cultivation. Both residents and farmers would advocate that investments in tourism would not lead to an increase in the flows, but to a better distribution in the territory, promoting sustainable tourism and directing it towards the rural part of the territory, relieving the pressure on villages. Finally, investments in the field of land management and for the decrease of hydrogeological risk appear to be crucial.

Conclusions
Both residents and farmers seem well aware of the vulnerability of their territory and of the strong connections between land abandonment, spread of woodlands and increased hydrogeological risk. To deal with these problems, they call for a stronger support from public authorities, especially with regard to interventions related to hydrogeological risk. Despite that Rural Development Funds proved to be effective and most of the farmers applied for them, they are not sufficient, i.e., even if a farmer restores his/her dry-stone walls and preserves them in perfect condition, if the terraces of neighboring properties, located upstream, are not well preserved, the hydrogeological problems remain, and his/her cultivations are still at risk. Farmers complain that they are the only ones currently taking care of the land, since it is precisely through farm management and drystone walls' restoration that they generate positive externalities and ecosystem services. Territorial management cannot just rely on their willingness to preserve dry-stone walls and continue to cultivate the terraces. If adequately supported, also through the UNESCO site Management Plan, farmers can represent, for local authorities, the most inexpensive and simple system of monitoring and managing this territory. There are many positive local examples supporting this concept and the desire to become more involved in the decision-making processes is evident.
Especially complex territories, characterized by cultural landscapes of high importance, but equally high fragility, have to deal with different critical issues due to significant changes in the social and economic structure, with new challenges to be undertaken. It is also clear that the idea of a "return to nature" as a positive strategy for any rural areas, quite widespread among the citizens, is conflicting with the importance assigned to the agricultural features of this area and with the goals of the UNESCO site and of the National Park. More recently, the Italian Forest Law introduced the possibility of removing secondary vegetation to restore abandoned cultivated land, testifying a change in the vision of public policies at the national level.
The extreme variability of the different UNESCO WHL sites, both at national and international levels, in terms of type, size and type of entities involved in their management, require to find the most suitable form of "governance" each time. The involvement of the population, through the study on landscape perception, critical issues, needs and expectations, carried out through questionnaires to residents and farmers, has proven to be a very effective tool to identify the focus of the Management Plan and some priority lines of action.
Moreover, actively involving the population, not only through the questionnaires but also through public meetings, increases the feeling among the community that the institutions are actually taking care of their problems. In fact, one of the most frequent criticisms was that in recent years, the Parks have disregarded the needs of the citizens, in favor of uncontrollably increasing tourist flows, with particularly negative consequences for the territory. The main limitation regarding the proposed methodology is due to the fact that it takes a lot of time to effectively involve the population, in particular to overcome the initial mistrust, and the support of local authorities is fundamental in organizing public meetings. Moreover, as often happens for landscape perception-based studies, another limitation is the lack of solid statistical validation [78].
The exchange of ideas, solutions and views between the population and the decisionmakers, was demonstrated to represent an effective tool in establishing priority guidelines for investments and to reconcile institutions and the community [79], to make Management Plans a more effective instrument in order to preserve and improve the landscape quality and therefore, the quality of people's lives. In fact, results of the questionnaires have been transferred into real strategies and actions for the Management Plan of the UNESCO site and we believe that sharing this kind of experience and methodology could be useful for other planners and scholars who are trying to turn different public participation approaches into real planning instruments. The applied methodology can be easily reproduced in similar situations, to target the management strategies more effectively, especially in the case of cultural landscapes characterized by high quality, complexity and fragility, that due to significant social and economic changes, have to deal with new challenges and transformations.   11.
