Regulation of nitrogen (N) loss from the agri-environment is a global challenge with dire consequences for food production and environmental management. This is also the case in Denmark where regulation largely relies on general measures for reducing N inputs. These measures have significantly reduced nitrogen emissions, but further reduction is needed to achieve sustainable low levels of N transport to freshwater and marine ecosystems in compliance with standards set by the EU Water Framework Directive. As an alternative to general regulation, we tested a watershed-based, collaborative planning approach, engaging stakeholders in solution identification. Six watersheds with substantial agricultural production were used as test areas. A collaborative planning process of two stakeholder workshops embedded within a scenario formulation process was executed. Stakeholder inputs about possible, desirable and sustainable futures were used to formulate scenarios, for which N reduction effects were calculated. Upon conclusion of this process, results were assessed using a structured evaluation method. Results indicate that the process we tested was successful in terms of (1) engaging relevant stakeholders, (2) providing relevant data, (3) achieving processual flexibility, (4) including local knowledge and (5) facilitating a creative and explorative process. On this basis, suggestions for improving collaborative planning processes are provided.

Rapid urbanization has caused significant land cover change (LCC) as well as changes in the land surface temperature (LST). However, the crucial land dynamic process, which could significantly contribute to the increase in LST and aggravation of the urban heat island (UHI) effect, remains poorly understood. Additionally, a strategy to optimize the most significant decreased land cover type in order to maximize the cooling effect is still lacking. Therefore, in this study, we selected the rapidly urbanizing and ‘hottest’ city in China, Fuzhou, as a case study. Two algorithms were selected to compare and obtain reliable LST data. A land use transfer matrix was used to detect critical contributions leading to the LST variations. The concept of cooling efficiency (CE) and the threshold value of efficiency (TVoE) are also proposed, defined, and calculated. The results show that LST values increased with increasing proportion of built-up land and sharply decreasing proportion of green space. Areas where LST differences exceed 4 °C cover 93% of the areas where green spaces decreased. Additionally, the LST variation is not only associated with the dominant land cover types but is also affected by the land cover transfer pattern and dynamics. Finally, we have calculated the TVoE of green space in Fuzhou city to be 4.55 ± 0.5 ha. This finding implies that when Fuzhou municipality implements urban/landscape planning, a green space area of 4.55 ± 0.5 ha is the most efficient to reduce the heat effect. This study extends the current understanding of LCC dynamics and LST variation. The concepts of the CE and TVoE are meaningful for landscape planning practice and can be used in other cases.

Scenario-building is a widely used tool to initiate discussions on future land uses. In scenarios possible futures can be explored and peoples' ideas as well as societal trends can be visualized by the use of maps, pictures and figures. With focus on agricultural nitrogen management, and point of departure in the farmers' decisions-regarding fertilizer inputs, crop rotations, land use, and drainage, landscape scenarios are formulated based on local ideas for future nitrogen management and general prospects for local development. The key research question addressed in this paper is how landscape scenarios can guide farmers to improve nitrogen management in smaller catchments dominated by farming. Participatory modelling was used to develop landscape scenarios, depicting the change of nitrogen emission as a result of changes in landscape management and agricultural practices. In the development of the scenarios we used an ArcMap based tool combining statistical data, experimental knowledge, nitrate leaching modelling and input from local stakeholders on biophysical as well as land use and farm management issues. The scenarios presented are the result of a collaborative planning experiment within the frames of the dNmark research alliance on nitrogen. Three different types of scenarios are presented and discussed and their effects in terms of N reduction are estimated. The three scenarios were called: River valley set-aside, constructed wetlands, and land zonation. All the modelled scenarios are estimated to have a positive effect i.e. a reduction of the level of N leached to the root zone. Based on the experience gathered in the project, the feasibility of using scenarios for future environmental planning in the agricultural landscapes is discussed. Further, this is related to the current discussion in Denmark on geographically targeted nitrogen regulation. It is concluded that the co-creative approach to formulation of scenarios can be an effective way of increasing the knowledge and ownership of possible future solutions, however the cost associated with this planning approach is likely to substantially higher that more traditional planning approaches. Consequently, the estimated transactions costs should be weighed against the expected benefits in terms of more successful implementation.

The comprehensive management of ecosystem service benefits and losses provided by landscapes under land-use reorganization is essential for optimizing and regulating landscape patterns and ecological conservation under rapid urbanization. Of the many studies focusing on the quantification and visualization of ecosystem services, few have explored the visualization characteristics of the different scales related to ecosystem services and losses. In this study, we selected one of the most important urban agglomerations in China—the Yangtze River Delta (YRD)—as a case for the analysis of ecosystem service benefits (which include environmental purification, climate and air regulation, and tourism and leisure) and losses (pollen allergies, air pollution, and the heat island effect) and the spatial patterns of both at multiple scales (grid divisions, administrative districts, and functional areas). We found that the value of ecosystem service losses in the YRD, with a net value of approximately −$42.02 × 106, was slightly higher than the value of ecosystem service benefits. The patterns of ecosystem service benefits were consistent with urbanization processes and patterns, with the natural landscape always serving as the main provider of ecosystem service benefits while the spatial pattern of the urbanized landscape determined the ecosystem service losses. Based on K-means clustering using randomly selected objects as an initial cluster center, we divided the YRD into different functional areas (optimized-, key-, and restricted-development zones) within the grid to create divisions with consistent biophysical properties, thereby avoiding the impact of urban administrative boundaries on the results. To facilitate closing the gap between positive and negative ecosystem outcomes in a politically feasible manner, we also identified functional areas in terms of ecosystem service bundles at the administrative district scale. This study obtains quantitative knowledge of functional areas based on ecosystem services benefits and losses, and helps guide sustainable urban agglomeration planning and development.

Farm diversification presents important development opportunities and challenges in peri-urban landscapes. New economic activities in left over farm buildings have traditionally been seen as a way to broaden the income base in particular in more remote areas. The positive economic effects needs to be balanced with the negative effects of the hidden urbanization that may convert rural areas to de facto urban areas and an inefficient use of demarcated industrial zones. Nowhere is the range of interests and competition for land greater than in peri-urban areas, which therefore represent special planning challenges. We investigated the patterns and processes of On-farm Business Structure Diversification (OFBSD) in Greater Copenhagen, with a particular focus on the use of three resources: land, buildings and rural assets for OFBSD activities as well as the motives behind farm purchase. The results are based on a case study with 146 farm owners. They show that 60% of all land owners were involved in OFBSD activities. No significant relationship with particular farm or farmer characteristics was detected. An estimation of resource use indicates that buildings are essential for 95% of the OFBSD activities, while 47% and 31% of the activities rely on the use of outdoor space or nearby rural assets. The results indicate that most activities are “footloose” and might as well be located in an urban setting. Furthermore, the results indicate that many farm owners purchased their farm based on a range of motives, combining both private and business considerations. This result has important planning implications, as physical planning regulation traditionally has focused on separate domains of interest, which corresponds poorly with current dynamics of OFBSD activities in peri-urban areas.

Production of food and fibres has traditionally been the main function of agriculture. In the last decades an increased focus on the importance of other functions has been discussed within the framework of agricultural and general land use multifunctionality. To a large extent farmers’ decisions and actions determine which functions their farming practices support. The extent of the production function is straightforward to identify and quantify but problems persist in rating functions such as ecosystem maintenance, housing, and amenity values. This paper presents a method to quantify and compare multifunctionality at farm level. Four main farm functions–production, residence, provision of wildlife habitats, and recreation–are selected to describe multifunctionality. In the quantification process indicators are identified to produce four aggregated function scores based on farm characteristics and activities. The farm data that support the indicators is derived from an interview survey conducted in 2008. The aggregated function scores vary with farm size as well as farm type; smaller, hobby-based farms in general score highest in the residence function whereas bigger, full-time farms score highest in the production, wildlife habitat, and recreation functions. This suggests that trade-offs between production development on the one side and environmental and recreational concerns on the other side may not be as high as expected. Farm of sizes 50–100 ha showed the highest multifunctionality–in this paper described as balance among functions–whilst smaller and bigger farms were biased towards mainly residence and production concerns, respectively. Challenges in quantifying functions still persist, but the suggested approach offer a method by which functionality can be compared among farms and among functions. Knowledge on the functional focus at farm level may assist both farmers and spatial planners in decision making regarding future management of agricultural landscapes.

The lack of generic methods to assess the environmental consequences of agricultural practices and the lack of consensus on monitoring and evaluation of environmental, agricultural and socio-economic effects of agri-environment schemes (AES) in EU Member States call for better evaluation methods. The ‘Agri-environmental Footprint’ project proposed to deal with these problems by establishing a new evaluation method, the Agri-Environmental Footprint Index (AFI). The AFI is an index customised to local stakeholder preferences, using expert knowledge for assessment of impacts and sensitivity, and indicators of the environmental state at farm level. In a Danish test case, agricultural practices at twenty-five farms in two groundwater protection zones were assessed. Data was collected from databases, registers, maps and interviews with farmers. The index was calculated for 1996/7 and 2006/7 to track temporal development and effects of entering an agri-environmental scheme. The Danish case demonstrated that the index can be used to track changes in environmental impacts and that entering agri-environmental scheme had a positive impact on the index value. However, the index should be used with caution. It is important to consider the robustness of each indicator: to assess whether changes will occur over time; whether changes are linked to management practices or external factors; and whether data are available up to date. Indicators dependent upon uptake data from agri-environmental schemes should be used with great caution. Retrospective use of stakeholder preferences is subject to uncertainty because preferences may have changed over time.

The subject of this paper is the views of farmers concerning their local landscape. In two contrasting Danish case study areas previously analysed in the 1990s, a small number of farmers have been interviewed regarding their views of the landscape and recent changes in their respective area including landscape changes. One of the areas (Hvorslev) is characterized by good conditions for agriculture, intensive husbandry production and a relatively stable landscape history. The other (Nees) has more marginal conditions and major changes in land use characterize the recent landscape history. We analyze the way in which the landscape is perceived by farmers and compare their views of the changing landscapes with the actual recorded changes on the one hand, and with other significant changes on the other. Farmers in both areas emphasized the same type of structural changes in agriculture and in the villages as significant, whereas only farmers in Nees indicated that the landscape had changed. When aske...

Among ecosystem services, the various categories of intangible services linked to human perception, such as aesthetics, recreational values and cultural heritage, must be rated alongside tangible services linked to physical processes, such as wildlife habitats, clean water and air, and filter- and buffer effects. This is a pre-requisite for a sustainable development with a balance between ecological, social and economic values. We analyse ecosystem services in areas of the urban fringe of Copenhagen, where the services provided are mainly related to human perception. We employ relatively simple methods in selected landscapes to qualify or quantify the aesthetics and recreational value, and the scale of the welfare economic value of these ecosystem services. In the first case area, the Danish state acquired 50 villas covering more than 50 ha in order to recreate open vistas and gain access for the public to the seaside. In the second case area, peri-urban open landscapes were protected by conservation orders, to maintain and enhance the benefits of green space for the growing urban population. We assess the value – in a broad sense – of these ecosystem services using three practical methods: a landscape evaluation in terms of services and qualities, an assessment of actual recreational use, and finally an assessment of the costs – in terms of residential development values lost – of securing the provision of aesthetic qualities and recreational opportunities. Searching the original planning documents we uncovered the original motivation for the land evaluation and decision. The arguments behind the designation and protection of the areas were primarily aesthetic and potentials for recreational use. The two areas receive annually 2–2.5 million and 400.000 visits respectively, proving their strong recreational value. The value of the demolished houses in the first case area exceeds 115 million €, and the value of the lost development opportunities in the second case area exceeds 280 million €. By combination the three methods, we substantiated that the intangible services may dominate the tangible in cases like these, stressing the need for planners to assess the role and value hereof.

Agri-Environment Schemes (AES) to maintain or promote environmentally-friendly farming practices were implemented on about 25% of all agricultural land in the EU by 2002. This article analyses and discusses the actual and potential use of impact models in supporting the design, implementation and evaluation of AES. Impact models identify and establish the causal relationships between policy objectives and policy outcomes. We review and discuss the role of impact models at different stages in the AES policy process, and present results from a survey of impact models underlying 60 agri-environmental schemes in seven EU member states. We distinguished among three categories of impact models (quantitative, qualitative or common sense), depending on the degree of evidence in the formal scheme description, additional documents, or key person interviews. The categories of impact models used mainly depended on whether scheme objectives were related to natural resources, biodiversity or landscape. A higher proportion of schemes dealing with natural resources (primarily water) were based on quantitative impact models, compared to those concerned with biodiversity or landscape. Schemes explicitly targeted either on particular parts of individual farms or specific areas tended to be based more on quantitative impact models compared to whole-farm schemes and broad, horizontal schemes. We conclude that increased and better use of impact models has significant potential to improve efficiency and effectiveness of AES.

Management of ecological entities in agricultural landscapes is often challenged by a complex ownership structure governed by a cadastral system dictated by agricultural interests and historical land use practices. The cadastral division is suspected to obstruct the deliverance of ecosystem services (ES) from the landscape. The objective of this analysis is to quantify the cadastral fragmentation of selected landscape-scale ES. Contiguous ecological units and landscape entities as designated in Danish municipal planning were analyzed. The designations comprised the existing ES represented by EU Natura 2000 areas, drinking water protection areas and valuable landscapes, and potential ES in areas designated for potential wetlands, afforestation and recreational trails. In each designated area the cadastral structure in terms of number of units, size, and number of affected properties was analyzed. In all cases a large number of rather small (mean area

Danish landscape research blossomed during the 1990s thanks to several transdisciplinary research programmes involving several institutions. The main themes of the programmes encompassed landscape change, landscape and biological diversity, nature and landscape management, use and monitoring of the countryside. The values of the Danish landscape pertain mainly to the coastal landscapes. The threats include the industrialization of the agricultural landscapes and, in places, urban sprawl. Les travaux de recherche consacrés aux paysages du Danemark ont connu, au cours des années 90, un essor considérable grâce à différents programmes de recherche transdisciplinaire menés au sein de plusieurs institutions et centrés sur l’évolution des paysages, la diversité paysagère et biologique, la gestion de la nature et du paysage, l’affectation et le suivi des campagnes. Les points forts du paysage au Danemark sont les paysages côtiers, tandis que les principales menaces proviennent de l’industrialisation des paysages agricoles et, par endroits, de la croissance urbaine.

With more than 60% of the land farmed, with vulnerable freshwater and marine environments, and with one of the most intensive, export-oriented livestock sectors in the world, the nitrogen (N) pollution pressure from Danish agriculture is severe. Consequently, a series of policy action plans have been implemented since the mid 1980s with significant effects on the surplus, efficiency and environmental loadings of N. This paper reviews the policies and actions taken and their ability to mitigate effects of reactive N (Nr) while maintaining agricultural production. In summary, the average N-surplus has been reduced from approximately 170 kg N ha?1 yr?1 to below 100 kg N ha?1 yr?1 during the past 30 yrs, while the overall N-efficiency for the agricultural sector (crop?+?livestock farming) has increased from around 20?30% to 40?45%, the N-leaching from the field root zone has been halved, and N losses to the aquatic and atmospheric environment have been significantly reduced. This has been achieved through a combination of approaches and measures (ranging from command and control legislation, over market-based regulation and governmental expenditure to information and voluntary action), with specific measures addressing the whole N cascade, in order to improve the quality of ground- and surface waters, and to reduce the deposition to terrestrial natural ecosystems. However, there is still a major challenge in complying with the EU Water Framework and Habitats Directives, calling for new approaches, measures and technologies to mitigate agricultural N losses and control N flows.

Ecological restoration is becoming a main component in nature management; hence, its definitions and interpretations of the underlying principles are widely discussed. In Denmark, restoration has been implemented for decades, and the LIFE Nature program has contributed to several large-scale projects. Our aim was to indicate tendencies in Danish nature policy by analyzing a representative sample of nature management projects. Using qualitative document analyses of official reports, we investigated how well 13 LIFE Nature cofinanced projects undertaken in Denmark fit with the principles of ecological restoration, as formulated in the nine attributes of the Society for Ecological Restoration's Primer on Ecological Restoration, and based on the five myths of ecological restoration. Objectives of the analyzed projects were divided into three categories: conservation of a single or a group of species; restoration of set-aside areas, mainly on abandoned agricultural land; and habitat management of Natura 2000 areas. Despite this grouping, improvement in living conditions for certain species associated with specific nature types was in focus in all projects. No projects considered or fulfilled all nine attributes. It seems that attributes associated with fundamental requirements for the existence of target species or habitats were more often fulfilled than attributes associated with continuity of the ecosystem as a whole, which indicated a focus on ecosystem structures rather than on processes. We found that the two assumptions of a predictable single endpoint (the myth of the Carbon Copy) and that nature is controllable (the myth of Command and Control) were notably frequent in the Danish projects. Often, the target ecosystem was associated with a semicultural landscape, and management focused on keeping the vegetation low and preventing overgrowth of colonizing trees. The results indicated that nature policy in Denmark and the LIFE Nature program are based on a control paradigm, with the focus on structures rather than on processes. Further, the results revealed that the definition and interpretation of ecological restoration is ambiguous, and according to land use history, there is a need for concepts and approaches to be clearly defined.

Land areas in collective ownership or use are traditionally referred to as commons. Through history, the common use and ownership has been a widespread means of regulating the use of natural resources. Changing economic conditions and technology spawned a process however where land use rights and landowner rights aggregated into the modern form of private ownership of individual farms with full management and owner rights. This process had obvious rationales in terms of production of marketable agricultural products. However, in the twentieth century increasing awareness of the supply of externalities such as clean groundwater and recreational opportunities from landscapes turned the attention once again to commons as an instrument for managing natural resources. Using groundwater and coastal landscapes as case examples, we pinpoint problems where outputs from the landscape are multiple consisting of a mix of public and private goods. In some instances central intervention is needed to ensure provision of public goods. In situations where transaction costs are too high to justify the guaranteed supply of goods, local initiatives, cooperatives and networks may be suitable regulatory alternatives to the predominant private and individualised ownership. It is concluded that the management regimes chosen should reflect the dominant functionality of the area in question.

The Agri-Environment Footprint Index (AFI) has been developed as a generic methodology to assess changes in the overall environmental impacts from agriculture at the farm level and to assist in the evaluation of European agri-environmental schemes (AES). The methodology is based on multicriteria analysis (MCA) and involves stakeholder participation to provide a locally customised evaluation based on weighted environmental indicators. The methodology was subjected to a validation and feasibility assessment in a series of case studies across the EU. The AFI approach was able to measure significant differences in environmental impact between farms that participated in an AES and non-participants. Wider environmental concerns, beyond the scheme objectives, were also considered in some case studies and the benefits for identification of unintentional (and often beneficial) impacts of AESs are presented. The participatory approach to AES evaluation proved efficient in different environments and political contexts. The approach proved to be appropriate for environmental evaluation of complex agri-environment systems and is available now to complement any evaluation conducted under the Common Monitoring and Evaluation Framework. The applicability of the AFI in routine monitoring of AES impacts and in providing feedback to improve policy design is discussed., JRC.J.5-Agriculture and Life Sciences in the Economy

In contemporary sciences dealing with cultural landscapes, the concept of multifunctionality has gained increasing attention in the last decade. The scientific literature displays several attempts to frame the concept (e.g DeVries 2000; Anon 2001; de Groot et al. 2002) but there is much frustration regarding proper sets of broadly based definitions and clear statements concerning the authors’ scientific points of departure (Anon 2001). Multifunctionality is on the one hand used to characterize the activities in the primary production sector, and the land use reflecting the material consequences of the various demands set by the society on land territories — these approaches relate to the agricultural understanding of multifunctionality. On the other hand, multifunctionality is used to characterize the landscape per se. The primary production sector (i.e. agriculture, forestry, horticulture and related land dependent activities) is considered having a primary or main function (production), and related joint productions, typically including a mix of material and non-tangible goods as well as a mix of private and public goods (externalities). Production of food and fibres is generally considered the primary products in this context, but the primary sector produces other material goods too, such as CO2 sequestration, groundwater recharge etc.
