By use of megafossil tree remains, preserved exposed on the ground surface, treeline shift over the past millennium was investigated at multiple sites along the Scandes in northern Sweden. Difference in thermal level between the present and the Medieval period, about AD 1000-1200, is a central, although controversial, aspect concerning the detection and attribution of anthropogenic climate warming. Radiocarbon-dated megafossil pines revealed that the treeline was consistently positioned as much as 115 m higher during the Medieval period than today (AD 2000-2010), after a century of warming and substantial treeline upshift. Drawing on the last-mentioned figure, and a lapse rate of 0.6 °C/100 m, it may be inferred that Medieval summer temperatures were about 0.7 °C warmer than much of the past 100 years. Extensive pine mortality and treeline descent after the Medieval warming peak reflect substantially depressed temperatures during the Little Ice Age. Warmer-than-present conditions during the Medieval period concur with temperature reconstructions from different parts of northern Fennoscandia, northwestern Russia and Greenland. Modern warming has not been sufficient to restore Medieval treelines. Against this background, there is little reason to view further modest warming as unnatural.","PeriodicalId":38803,"journal":{"name":"Landscape Online","volume":"42 1","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2015-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69300975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attractive landscape and experience of nature are the most important reasons to visit this region and to spend leisure time there. Particularly mountain meadows, raised bogs and mixed forests are highly appreciated. Deforestation, industrial development and the decline of biodiversity would reduce attractiveness for visitors. We also assessed whether the tourism sector is prepared to contribute to the funding of nature conservation and landscape management. Use of general tax revenues is favoured, but other modes would also be accepted, e.g. a nature tax. Willingness to pay (WTP) is ranging between €0.75 and €1.36 per guest per night by TSP, or between €1.06 and €2.73 per day by visitors. With respect to landscape preference and WTP we found in some cases significant differences among visitors, depending on region of residence, age and education level. A major part of the annual costs for nature conservation and landscape could be covered by public funds (taxes), if the results of the WTP approach were understood as a sign of societal demand and a call to action.","PeriodicalId":38803,"journal":{"name":"Landscape Online","volume":"41 1","pages":"1-23"},"PeriodicalIF":0.0,"publicationDate":"2015-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69300962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how this knowledge will foster decisions that lead to more desirable outcomes and analyses necessary to transition to sustainability remains a critical theoretical and empirical question for basic and applied research. We argue that we are still underestimating the tendency to lock into certain patterns that come at the cost of the ability to adjust to new situations. This rigidity limits the ability of persons, groups, and companies to respond to new problems, and can make it hard to learn new facts because we pre-select facts as important, or not, in line with our established values. Changing circumstances demand to reappraise values like in the case of Pirsig's monkey and its rice. There is an urgent need to go beyond such local, static and short-term conceptions, where landscape sustainability has been incorrectly envisioned as a durable, stable condition that, once achieved, could persist for generations. We argue that to manage a global transition toward more environmentally efficient and, therefore, more sustainable land-use we have to reappraise societal values at the root of overregulation and rigidity.","PeriodicalId":38803,"journal":{"name":"Landscape Online","volume":"40 1","pages":"1-19"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69300898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interrelations between ecosystem services and socioeconomics have scarcely been considered in the context of urban-rural areas. We investigated the spatial gradients and the mutual linkages of several ecosystem services and socioeconomic variables in the urban-rural areas of Leipzig, Germany, and Kunming, China. The results showed some regularities in the spatial patterns of ecosystem services and socioeconomic dimensions in both study areas. Habitat quality and f-evapotranspiration of Leipzig and habitat quality of Kunming demonstrated apparent increasing trends along all gradient patterns. However, the other ecosystem services presented divergent spatial variabilities in different gradient patterns. Road density, urban fabric and population density showed identical declining trends in both case study areas. Differently, household size, housing area as well as unemployment rate in Leipzig presented inconsistent spatial dynamics with considerable fluctuations. With regard to the gradient interrelations, road density, urban fabric and population density were strongly correlated with most ecosystem services in both case study areas. In contrast, the gradients of household size, housing area and unemployment rate of Leipzig showed inconsistent correlations with the ecosystem services gradients. Our study provides evidence to the argument that typical patterns of ecosystem service gradients do not exist in different urban-rural areas.","PeriodicalId":38803,"journal":{"name":"Landscape Online","volume":"39 1","pages":"1-31"},"PeriodicalIF":0.0,"publicationDate":"2015-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69300871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Often, landscapes or landscape types are treated in the literature as essentialist or at least as uncontested categories. We analyse two examples of local controversies about wind energy, in which “landscape” is employed by supporters and opponents alike, from a poststructuralist and discourse theoretical angle. The aim is to identify and compare landscape constructs produced in the micro discourses of wind energy objectors and proponents at local level (a) within each case, (b) between the two cases and (c) with landscape constructs that were previously found in macro discourses. One major finding is that several different landscapes can exist at one and the same place. Furthermore there seems to be a relatively stable set of competing landscape concepts which is reproduced in specific controversies. The paper concludes by highlighting  practical consequences and by identifying promising avenues of further research.","PeriodicalId":38803,"journal":{"name":"Landscape Online","volume":"38 1","pages":"1-18"},"PeriodicalIF":0.0,"publicationDate":"2014-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69300819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participation of stakeholders is still a major methodical and conceptual challenge for implementing ES. Therefore, we conducted an online survey and a literature analysis to identify benefits and challenges of the application of ES in participatory processes. The results show that the purpose of stakeholder engagement is very diverse as a result of varying objectives, spatial scales and institutional levels of analysis. The complexity, terminology and (lacking) coherent classification of ES are pivotal aspects that should be accounted for in the design of studies to improve stakeholder participation. Although limitations of time and financial resources are bigger challenges than ES related ones, tailoring communication strategies and information for different stakeholder groups are of major importance for the success of ES studies. Results support the view that the potential benefits of applying ES, e.g., consensus finding, and development of integrated solutions, cannot be realized consistently across the different spatial scales and decision-making levels. Focusing on stakeholder processes represents a means to increase the relevance, reliability and impact of study results and to move participation in ES research from theory to reality.","PeriodicalId":38803,"journal":{"name":"Landscape Online","volume":"37 1","pages":"1-25"},"PeriodicalIF":0.0,"publicationDate":"2014-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69300770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A two-stage empirical survey was conducted integrating a citizen and an expert Delphi survey. The results show that the noise from the motorway heavily affects the quality of life in health, economic and ecological respects. Sustainable noise abatement should take into consideration ecological and social aspects like landscape integration and contribution to local development due to the unique location of the municipality. Enclosed motorway canopies are particularly beneficial to meet these criteria. The costs for sustainable noise abatement measures should be weighted as less important; however, financial costs are crucial for the federal government due to the requirements of the Federal Pollution Control Act. Hence, residents and experts assume that noise barriers as the cheaper noise abatement measures will be implemented. However, the results of the study and the latest developments in the expansion plans suggest that the implementation of enclosed motorway canopies, which go beyond the legal requirements, is feasible through extensive citizen participation and community-specific planning.","PeriodicalId":38803,"journal":{"name":"Landscape Online","volume":"36 1","pages":"1-23"},"PeriodicalIF":0.0,"publicationDate":"2014-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69300755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Information on LULC is needed for the assessment of ecosystem services and is used as input data for mapping and modelling. This information is important for decision-making and management of ecosystems and landscapes. In this study, LULC were analysed in two agricultural areas in Northern Germany by means of a pixel-based maximum likelihood classification approach of 11 Landsat TM 5 scenes between 1987 and 2011 followed by a post-classification refinement using the tool IRSeL. In this time period, grassland declined by about 50 % in both case study areas. This loss in grassland area can be associated with changes in provisioning ecosystem services as the supply of fodder and crops and the number of livestock declined from 1987 to 2007. Furthermore, an on-going increase in maize cultivation area, which is nowadays more and more used as biomass for biogas production, documents the addition of another provisioning service, i.e., biomass for energy. Combining remote sensing and research on ecosystem services supports the assessment and monitoring of ecosystem services on different temporal, spatial, and semantic scales.","PeriodicalId":38803,"journal":{"name":"Landscape Online","volume":"35 1","pages":"1-24"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69300702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, the current state of the art of ecosystem service science regarding spatial localisation, indication and quantification of multiple ecosystem service supply and demand is reviewed and discussed. Concepts and tables for regulating, provisioning and cultural ecosystem service definitions, distinguishing between ecosystem service potential supply (stocks), flows (real supply) and demands as well as related indicators for quantification are provided. Furthermore, spatial concepts of service providing units, benefitting areas, spatial relations, rivalry, spatial and temporal scales are elaborated. Finally, matrices linking CORINE land cover types to ecosystem service potentials, flows, demands and budget estimates are provided.

Because these ecosystems are still undergoing fundamental changes, the interest of the society is to know more about future developments and their ecological impacts. To describe and analyze these changes, scenarios can be developed and an assessment of the ecological changes can be carried out subsequently. In the project \"Landscape Saxony 2050\"; a methodology for the construction of exploratory scenarios was worked out. The presented methodology provides a possibility to identify the driving forces (socio-cultural, economic and ecological conditions) of the landscape development. It allows to indicate possible future paths which lead to a change of structures and processes in the landscape and can influence the capability to provide ecosystem services. One essential component of the applied technique is that an approach for the assessment of the effects of the landscape changes on ecosystem services is integrated into the developed scenario methodology. Another is, that the methodology is strong designed as participatory, i.e. stakeholders are integrated actively. The method is a seven phase model which provides the option for the integration of the stakeholders' participation at all levels of scenario development. The scenario framework was applied to the district of Gorlitz, an area of 2100 sq km located at the eastern border of Germany. The region is affected by strong demographic as well as economic changes. The core issue focused on the examination of landscape change in terms of biodiversity. Together with stakeholders, a trend scenario and two alternative scenarios were developed. The changes of the landscape structure are represented in story lines, maps and tables. On basis of the driving forces of the issue areas \"cultural/social values\" and \"political control\", three scenarios were developed up to the time horizons in 2030 and 2050. They are titled \"Trend\", \"Tradition and Ecology\" and \"Technology and Energy\". These scenarios differ markedly in the degree of the future lignite exploitation, in the use of renewable energy and in the environmental compatibility of the agricultural production. In total, the investigation shows that the integration of the ecosystem services approach into the scenario technology has brought new aspects. However, the procedure became more complex. For the development of the scenarios a precise definition of the driving forces turned out to be essential. The experiences of the project further show that only two or at most three key driving forces (KDF) can be distinguished really sensibly or can be looked at in their interactions. It could be shown that from these results itself concrete measures can be derived which support desirable developments or counteract against undesirable effects.
