Relationships between visual landscape preferences and map-based indicators of landscape structure

There is increasing awareness of the need to monitor trends in our constantly changing agricultural landscapes. Monitoring programmes often use remote sensing data and focus on changes in land cover/land use in relation to values such as biodiversity, cultural heritage and recreation. Although a wide range of indicators is in use, landscape aesthetics is a topic that is frequently neglected. Our aim was to determine whether aspects of landscape content and configuration could be used as surrogate measures for visual landscape quality in monitoring programmes based on remote sensing. In this paper, we test whether map-derived indicators of landscape structure from the Norwegian monitoring programme for agricultural landscapes are correlated with visual landscape preferences. Two groups of people participated: (1) locals and (2) non-local students. Using the total dataset, we found significant positive correlations between preferences and spatial metrics, including number of land types, number of patches and land type diversity. In addition, preference scores were high where water was present within the mapped image area, even if the water itself was not visible in the images. When the dataset was split into two groups, we found no significant correlation between the preference scores of the students and locals. Whilst the student group preferred images portraying diverse and heterogeneous landscapes, neither diversity nor heterogeneity was correlated with the preference scores of the locals. We conclude that certain indicators based on spatial structure also have relevance in relation to landscape preferences in agricultural landscapes. However, the finding that different groups of people prefer different types of landscape underlines the need for care when interpreting indicator values.     

Spatio-temporal dynamics and evolution of land use change and landscape pattern in response to rapid urbanization

Analyzing spatio-temporal characteristics of land use change is essential for understanding and assessing ecological consequence of urbanization. More importantly, such analysis can provide basic information for appropriate decision-making. By integrating historical high spatial-resolution SPOT images and spatial metrics, this study explored the spatio-temporal dynamics and evolution of land use change and landscape pattern in response to the rapid urbanization process of a booming-developing city in China from 1996 to 2006. Accurate and consistent land use change information was first extracted by the change detection method proposed in this study. The changes of landscape pattern were then analyzed using a series of spatial metrics which were derived from FRAGSTATS software. The results indicated that the rapid urbanization process has brought about enormous land use changes and urban growth at an unprecedented scale and rate and, consequently, given rise to substantial impacts on the landscape pattern. Findings further revealed that cropland and water were the major land use types developed for urban sprawl. Meanwhile, the landscape pattern underwent fundamental transition from agricultural-land-use dominant landscape to urban-land-use dominant landscape spanning the 10 years. The results not only confirmed the applicability and effectiveness of the combined method of remote sensing and metrics, but also revealed notable spatio-temporal features of land use change and landscape pattern dynamics throughout the different time periods (1996–2000, 2000–2003 and 2003–2006).     

The emerging role of visual resource assessment and visualisation in landscape planning in Switzerland

The evolution of our understanding of landscape planning and therefore of landscape as a visual resource occurred in parallel with the changes of perception of spatial planning (urban and regional planning), since landscape planning is part of spatial planning. Already in the 1970s the visual landscape was an issue in spatial planning. This can be traced back to the romantic period when the close emotional ties with one’s home country were very important.With the emerging discussion at the end of the 1970s about ecology and ecological planning, more and more the components of natural science of ecological planning were discussed, at the expense of the visual landscape and aesthetics. With the improvement of the possibilities of the digital 3-dimensional (3D) representation of landscape, it seems that landscape as visual resource has once again become more important in the discussion. 3D visualisation will support participation in the planning process and will become an important part of decision support systems in spatial planning. The use of virtual landscapes will help to study processes in the landscape such as fragmentation of landscape and/or urban sprawl.     

New wilderness in the Netherlands: An investigation of visual preferences for nature development landscapes

The present research investigated visual preferences for nature development landscapes among 500 residents from six plan areas in The Netherlands. Significant differences in relative preferences for wild versus managed scenes were found between landscape types and respondent groups. Development of wild nature was evaluated less positively in a forested area than in more open, rural areas. Among the background variables included in the study, place of residence, age, socio-economic status, farming background, preference for green political parties, and recreational motives were found to be systematically related to relative preferences for wild versus managed nature scenes, accounting for 16% of the variance in preference ratings. These findings are discussed within an applied decision making context in The Netherlands.     

Landscape characteristic aesthetic structure: Construction of urban landscape characteristic time-spatial pattern based on aesthetic subjects☆

The paper presents means and models of city-landscape characteristic structure construction on the aspect of landscape aesthetics subjects, which is called the landscape characteristic aesthetic structure and in short as LCAS. In this paper, the steps of LCAS research are as follows:Describes the concepts of the landscape characteristic aesthetic structure (LCAS), and expounds the LCAS properties: systematic quality, temporal and spatial quality, and virtual existence.Learns from typology research methods, discusses the elements and types needed in a landscape characteristic aesthetic system, and constructs research method for LCAS pattern. As for the temporal dimension, the dynamic evolution and interaction expressed in LCAS between the “tradition” and “modernity” landscapes conflict. As for the spatial dimension, this paper explores the LCAS patterns in macroscopic scope of city group, the middle scope of single cities and the microcosmic scope of urban spaces with questionnaires and examples research.Uses pattern language to express different LCAS types in the temporal and spatial system.We develop the patterns of various LCAS types with graphical patterned representation, as well as construct the LCAS research method and theory which is based on the general people's aesthetic standards and sensibilities to build city characteristics and urban landscapes as a guidance.     

Remote sensing and GIS in modeling visual landscape change: a case study of the northwestern arid coast of Egypt

Land use planners in many countries have recognized the importance of the aesthetic values of landscape. Their desire to incorporate these values into decision-making processes has created a need to identify valid ways to quantify the scenic characteristics of landscapes. This has led to an increasing interest in the use of spatial data and geographic information systems (GIS) methodology in assessing visual attributes of the landscape. The objective of the present study is to assess the visual changes in a rapidly developing coastal area of Egypt using remotely sensed data (satellite images and aerial photographs) and raster GIS modeling. The analysis assesses changes between a period characterized by a vernacular, relatively natural landscape (1950s) and the beginning of the exploitation of the region for resorts (1990s). Using land use/land cover classes extracted from the satellite images and aerial photographs, four visual attributes of landscape are identified: land use/land cover diversity, activity (degree of naturalness), proximity to the shoreline, and topographic variety. A composite index is also developed. Although these attributes and the composite index rely mostly on the type of land use/land cover information on the landscape under consideration, the adopted techniques succeed in detecting several changes in the attributes, spatially locating them and mapping the magnitude of their changes. This study demonstrates what can be done to analyze and assess what is usually considered an incommensurable resource, the visual attributes of landscapes. It also reveals the extent of the impact of unplanned or ill-planned activities on one of the fragile resources of arid landscapes.     

Assessment of landscape composition and configuration via spatial metrics combination: conceptual framework proposal and method improvement

Landscape transformations have been a central topic in landscape ecology due to their influence on ecosystem services and biodiversity conservation. Landscape dynamics can be very complex and one of the most difficult issues to analyse is the contribution and the effects of landscape composition and configuration changes to the overall impact. We enhanced an existing approach designed to assess landscape transformation via metrics combination. Based on the area and the number of patches, we defined a Landscape Dynamics Typology (LDT) with eight different dynamics. The agro-forestry areas dynamics between 1990 and 2006, in Portugal, is presented as a practical example to show the implementation steps and the outputs obtained. A diagnostic tree is provided to help identify which dynamics are present. This new method provides detailed results concerning the location of the different dynamics within a landscape. The LDT is a versatile tool and is able to accommodate upgrades.     

Measuring the spatial quality of bedrooms in nursing homes with visual environmental performance

The elderly’s perception of their environment largely depends on acquired visual information. This study provides a quantitative analytical method for designing bedrooms in nursing homes by developing a computational model that uses viewing distance, viewing angle, and viewing field as variables. The model is utilized to measure a range of visual environmental properties, including privacy, accessibility, permeability, and visibility, which reflect the quality of bedrooms in nursing homes. The suitability levels of bedroom planes for the elderly and their main living functions as well as the fitting degree of the functional layout are calculated based on these data. After validating the computational model’s feasibility, this study optimizes the typical schemes of single and double rooms in nursing homes. Results reveal certain advantages of the arrangement where bathroom doors are set toward the inside of the bedroom and double rooms have a large width. The computational model can be used in measuring the spatial quality of bedrooms in nursing homes and as a mathematical model for related algorithm design and software programming to assist in the design and optimization of bedrooms for the elderly.     

Using GIS and landscape metrics in the hedonic price modeling of the amenity value of urban green space: A case study in Jinan City, China

Urban green spaces have important amenity values that include provision of leisure opportunities and aesthetic enjoyment. However, most of these values lack a market price. Consequently, they are usually ignored or underestimated by urban planning policy-makers, with the result that remnant urban green spaces are being gradually encroached upon by urban sprawl. As a result, quantitative information regarding the implicit, non-market price benefits from urban green space is urgently required. Properties bought and sold on the market are compound commodities that embody amenity values and people are willing to pay to live in the proximity of local amenity environment. Thus hedonic models, which use such properties as proxies, can often be employed to quantify environmental amenities. In China, residential housing reform (in place since 1998) has terminated the traditional residential welfare system, and made it possible to quantify the monetary value of green space amenities based on hedonic pricing models. This study was conducted in Jinan City, and will help address the previous absence of the application of hedonic price models to the valuation of urban green space amenities in mainland China. GIS and landscape metrics were used in determining hedonic price model variables. As expected, the results proved that the hedonic pricing model performed well using this approach, and accordingly it was further improved. Results also confirmed the positive amenity impact of proximate urban green spaces on house prices, and highlighted the preferences of homeowners in Jinan City. Green space amenity variables that were statistically significant at the 5% level included the size–distance index of scenery forest, accessibility to park and plaza green space types, and the percentage of urban green space. In addition, land-use patch richness, the location sector and the education environment also proved to be highly significant variables. The results of the study should provide insights to policy-makers involved in urban planning.     

Changes in agricultural landscape pattern and its spatial relationship with forestland in the State of Selangor, peninsular Malaysia

In Malaysia, the development of two major agricultural crops, i.e. oil palm and rubber, is one of the primary causes of forest loss. However, understanding of this relationship has not been quantified, which is vital to improve the planning and management of the agricultural land uses. To understand the relationship, this study addresses their dynamic change, patchiness and spatial relationship with forestland in the State of Selangor, Malaysia as a case study. Data development and analysis were based on three land-use maps of 1966, 1981 and 1995 where forest and, wetland forest and marshland land use categories were referred to as forestland. Two defined natural landscapes; forest and wetland landscapes were used as a basic unit of analysis to determine the patchiness of the agricultural lands at the expense of large tract of forestland. During the periods studied, oil palm area increased whereas rubber area reduced. The development of oil palm had caused loss much of forestland, particularly wetland forest and marshland. Its expansion at the expense of large tract of wetland forest and marshland earnestly occurred between 1966 and 1981 but slowed down between 1981 and 1995. By using the landscape type approach this study recommended a way to determine the patchiness of the agricultural lands at the expense of large tract of forestland. With these findings, we conclude that it is important to understanding the relationship quantitatively in order to describe the implications for land development of the agricultural crops.     

Spatial and temporal dynamics of land use pattern in Turkey: A case study in İnegöl

Recognition and understanding of landscape dynamics as a historical legacy of disturbances are necessary for sustainable management of forest ecosystems. This study analyzed forest dynamics and spatial–temporal changes in land use/land cover pattern in a sub-temperate like alluvial forest land with 1778 km² area along the Eagan Sea coast of Turkey (İnegöl). This area is studied by comparing Landsat images from 1987 to 2001 and evaluated with spatial analyses of forest cover type maps from 1972, 1983, 1993 to 2004 using GIS. The study investigated temporal changes of spatial structure of forest conditions over the period using Fragstats™.The results showed that the forested areas increased both in between 1972 and 1993 years (3.3%) and between 1987 and 2001 years (6.7%). In terms of spatial configuration, İnegöl forests are generally fragmented in the latter periods due to intensive forest utilization, illegal use, expansion of settlements and infrastructural development in the lowlands. Land use pattern significantly changed over time depending on a few factors such as unregulated management actions, social pressure and demographic movements. In conclusion, land use changes have developed in favor of forestry over time between 1972–1993 and 1987–2001. The study revealed that demographic movements have a minor effect on landscape dynamics. Both spatial and temporal changes and the factors affecting these changes should be determined for developing sustainable management of forest resources.     

Economic clusters: A bridge between economic and spatial policies in the case of Beijing

Economic clusters have been recognised as important elements of urban and regional economic strategies, but their role in spatial planning is under-appreciated. This paper examines the initiatives and outcomes of economic clusters in relation to urban spatial planning in the periods of planned and market economies in China. Through an examination of the planning and development practices in Beijing, the effect of economic clusters in facilitating local growth and shaping urban spatial structure is revealed. The significance of economic clusters in achieving synergy between economic and spatial policies is discussed.     

Interaction between farming systems, riparian zones, and landscape patterns: a case study in western France

We analyze the factors driving land use within and outside riparian zones in four small (about 800 ha) watersheds in Brittany. The results show a difference between riparian and non-riparian zones (less used for grassland), but other factors are also important, such as field size or farm management type. In large farms, small fields are easily abandoned. A multivariate analysis with farm and field characteristics explains 30% of land use variation. Our results suggest that farm type deflects land use from the regional mode, so it is important, in the implementation of environmental zoning, to assess constraints at the farm level.     

Exploring farmer's knowledge as a source of information on past and present cultural landscapes: A case study from NW Spain

The primary goal of this research was to explore the potential of farmer's knowledge as a source of information on the past and present cultural landscapes, focusing on the land-use system, the cultural heritage, and the farmer's perception of landscape changes, from the 1950s to the present day. For this purpose, 42 semi-structured interviews were conducted from a random sample of 10% of the villages in an area of the Northern Mountains of Galicia (NW Spain). As shown in farmers’ reports, the main crops in the 1950s were wheat or rye, potatoes or maize (only near the coast) and turnips. Scrubland areas were an essential resource for pasture, litter, temporary crops and charcoal, whereas deciduous forest was mainly used as a source of wood for carpentry, firewood and litter. Agriculture was the main economic activity, whereas crafts and other activities in the fisheries or forestry industry were secondary. Granaries, watermills and stone laundry basins were the most frequent elements of built heritage that was mentioned in the interviews. Farmers were also comprehensively aware of the broad changes that occurred in the landscape. The results indicate that farmer's knowledge is a valuable source of information for documenting past and present land-use practices, local cultural heritage and changes in the landscape, all of which are helpful for the design of landscape-orientated policies. Moreover, observed ancestral cultural practices, such as extensive grazing in scrubland areas, may be promoted as strategies for helping the sustainability of cultural landscapes in the study area and in other areas with similar characteristics.

Empowering nature conservation in Japanese rural areas: a planning strategy integrating visual and biological landscape perspectives

There has been much discussion about the importance of nature conservation, but a concrete strategy has been lacking. Most conservation measures are reactive to development projects that threaten the sites’ conservation values. There is little synergy between nature conservation and other competing land-use policies. Furthermore, conservation messages are not communicated well because there are few opportunities for those involved in research, policy formation and policy implementation to interact. We illustrate the methodological framework that can be used to address these issues in rural nature conservation by presenting our research conducted in the Arai-Keinan district of Niigata, Japan. The proposed methodological framework consists of integrating visual and biological landscape approaches to understand the area’s natural environment and using participatory research to narrow the communication gaps among those involved. We stress the importance of expressing the research results and recommendations on a map as a strategy for effective nature conservation. The graphical presentation of a map not only allows for clearer delivery of messages from researchers to government officials and residents, but also facilitates coordination among competing land-use policies. The map is the central ammunition in reversing the reactive nature of conservation policies to that of a “preemptive” nature. Future research directions to gain stronger political support are also discussed.     

Agricultural landscapes between intensification and abandonment: the expectations of the public in a Central-Alpine cross-border region

The aim of this study is to find out what locals and tourists in a Central-Alpine, multilingual cross-border region expect from an Alpine landscape, with a special focus on agriculture. Using a standardised questionnaire, we carried out more than 3500 face-to-face interviews with locals and tourists in Tyrol (Austria) and South Tyrol (Italy). The questionnaire comprised (1) content-related questions and (2) questions to collect demographic data on the interviewees. We employed nonparametric methods to analyse the survey results and differences between demographic groups. More than 70% of the study participants liked traditional land-use and did not have major reservations about agricultural intensification or extensification. Of those interviewed, 73% were in favour of giving public financial support to farmers. The findings obtained in this study suggest broad acknowledgement and acceptance of environmental compensation schemes and the maintenance of extensive and traditional land-use systems.     

Landscape diversity and land use planning: a case study in Bavaria

A maximum of landscape diversity is to be regarded as a helpful target as well as an analytical tool to detect actual planning deficits. First of all, specific indicators and targets for ecosystem and landscape levels will be defined. Ecosystem types are derived from landscape ecological site conditions, and are combined with the demands of minimal areas related to present and potential ecosystem types.The suitability of management practices for the site conditions, and the requirements mentioned above, will together form the basis on which a target landscape in its pattern, and the management practices suggested can be mapped. In comparison with the present use of the landscape, measures are derived which indicate that the target of a high landscape diversity has real practical meaning: conversion of about 15% of the arable land into forests and grasslands as one result of this study fits into the political and administrative programmes already established. In addition, four modification categories of the actual usage are mapped and described in size and number in this case study. The basic assumptions of this approach will be explained, to provide further working hypotheses for an interdisciplinary and integrative research into landscape ecology in rural landscapes.     

Connecting landscapes: examining and enhancing the relationship between stakeholder values and cultural landscape management in England

In England’s post-Brexit environment, as the nation’s approach to cultural landscapes is reassessed, understanding what stakeholders value and how they currently engage with landscape management is likely to be increasingly important. This study explores this at a localised scale. Examining the value of an ecosystems services perspective, it focuses on two case-study landscapes in Gloucestershire. Using interviews, focus groups, mapping tasks and questionnaires it examines how stakeholder values intersect with current policies and practices. Based on this analysis, it suggests the need for greater integration and knowledge exchange between stakeholders to ensure the sustainability of landscape management. It suggests new strategies, such as a centralised e-portal of resources, are required to ensure awareness and dialogue between stakeholders. This study is part of a larger European project comparing how the values of stakeholders in heritage landscapes can be better integrated into cultural landscape management.     

European and natural landscapes as carriers of place identity: a correlational study in Italian and Spanish regions

This study investigated whether European, Mediterranean and natural landscapes might trigger identification responses among residents of Mediterranean Europe. The participants (N = 546) were students from three Italian and three Spanish regions who rated their level of place identification by looking at eight pictures of prototypical landscapes, each depicting a unique combination of attributes in a 2×2×2 research design (European/non-European, Mediterranean/non-Mediterranean and natural/built). The results confirmed both European and natural landscapes as stronger carriers of identification than non-European and built landscapes, respectively, whereas no differences emerged between Mediterranean and non-Mediterranean landscapes. The statistical analysis of two-way interactions showed the amplification effect of the combined European–natural landscape, whilst a less clear picture emerged from the other two interactions. These findings suggest that landscape images may be used to foster a more inclusive identity at the supranational level and thus increase the sense of belonging among European citizens.
