Tidskriftsartikel (refereegranskat)abstract
- Cultural ecosystem services (CES) are nonmaterial benefits that people obtain from ecosystems. The CES subcategories cover a wide range of domains (e.g. recreation, conservation of cultural heritage, human-nature relations). The CES concept has been proposed to acknowledge the nonmaterial values linking people and nature in social-ecological systems. Agricultural landscapes are outstanding examples of complex social-ecological systems where synergies and trade-offs between production and conservation determine the CES values. Europe is still rich in such landscapes/systems with outstanding cultural and natural values that deliver a multitude of CES. In this paper, we address the knowledge and perceptions of identified experts on the role of CES in the management of European agricultural landscapes. To achieve this goal, we developed a questionnaire on CES which was answered by experts working with various issues of European agricultural landscapes, including sustainable agriculture, landscape ecology, grassland management, nature conservation, cultural heritage conservation, environmental policy, sustainability research and rural development. The results show a wide knowledge and acceptance of the CES concept within such expert communities. Especially the aesthetic, cultural heritage, educational and recreational values were considered the most relevant CES subcategories. Interdisciplinary approaches, landscape planning and integrative science-policy approaches were perceived as the most promising methodologies to improve the CES approach for policy and management. Our results also show that according to experts the CES concept is still far from practical implementation in policies that target agricultural landscapes. In order to sustain such systems, we suggest the better implementation of inter- and transdisciplinary research for the development of CES-integrative policy and decision-making.

Tidskriftsartikel (refereegranskat)abstract
- Improving our understanding of the relationships between biodiversity and the delivery of ecosystem services is crucial for the development of sustainable agriculture. We introduce a novel framework that is based on the identification of indicator species for single or multiple ecosystem services across taxonomic groups based on indicator species analyses. We utilize multi-species community data (unlike previous single species approaches) without giving up information about the identity of species in our framework (unlike previous species richness approaches). We compiled a comprehensive community dataset including abundances of 683 invertebrate, vertebrate and plant species to identify indicator species that were either positively or negatively related to biological control, diversity of red-listed species or crop yield in agricultural landscapes in southern Sweden. Our results demonstrate that some taxonomic groups include significantly higher percentages of indicator species for these ecosystem services. Spider communities for example included a higher percentage of significant positive indicator species for biological control than ground or rove beetle communities. Bundles of indicator species for the analysed ecosystem service potentials usually included species that could be linked to the respective ecosystem service based on their functional role in local communities. Several of these species are conspicuous enough to be monitored by trained amateurs and could be used in bundles that are either crucial for the provision of individual ecosystem services or indicate agricultural landscapes with high value for red-listed species or crop yields. The use of bundles of characteristic indicator species for the simultaneous assessment of ecosystem services may reduce the amount of labour, time and cost in future assessments. In addition, future analysis using our framework in other ecosystems or with other subsets of ecosystem services and taxonomic groups will improve our understanding of service-providing species in local communities. In any case, expert knowledge is needed to select species from the identified subsets of significant indicator species and these species should be validated by existing data or additional sampling prior to being used for ecosystem service monitoring.

Tidskriftsartikel (refereegranskat)abstract
- The assessment of effects of anthropogenic disturbance on biodiversity (BD) and ecosystem services (ES) and their relationships are key priorities of the Intergovernmental Panel for Biodiversity and Ecosystem Services. Agricultural landscapes and their associated BD provide multiple ES and it is crucial to understand how relationships between ES and BD components change along gradients of landscape complexity. In this study, we related eight ES potentials to the species richness of five invertebrate, vertebrate and plant taxonomic groups in cereal farming systems. The landscape complexity gradient ranged from areas dominated by annually tilled arable land to areas with high proportions of unfertilized, non-rotational pastures and uncultivated field borders. We show that after accounting for landscape complexity relationships between yield and bird richness or biological control became more positive, but relationships between bird richness and biological control became less positive. The relationship between bird and plant richness turned from positive to negative. Multidiversity (overall biodiversity), was positively related to landscape complexity, whereas multifunctionality (overall ES provision), was not significantly related to either one of these. Our results suggest that multidiversity can be promoted by increasing landscape complexity; however; we found no support for a simultaneous increase of several individual ES, BD components or multifunctionality. These results challenge the assumption that bio-diversity-friendly landscape management will always simultaneously promote multiple ES in agricultural landscapes. Future studies need to verify this pattern by using multi-year data, larger sets of ES and BD components and a study design that is appropriate to address larger spatial scales and relationships in several regions.

Effects of farm type on food production, landscape openness, grassland biodiversity, and greenhouse gas emissions in mixed agricultural-forestry regions
- 2021
-
Ingår i: Agricultural Systems. - : Elsevier BV. - 0308-521X .- 1873-2267. ; 189

Tidskriftsartikel (refereegranskat)abstract
- Context: The global demand for food is expected to continue increasing for decades, which may drive both agricultural expansion and intensification. The associated environmental impacts are potentially considerable but will depend on how the agricultural sector develops. Currently, there are contrasting regional developments in agriculture; expansion and/or intensification in some regions and abandonment in others, as well as changes in the type of farming. However, the environmental consequences of changes in farm type are not well understood. Objective: We have evaluated the impacts of farm type on food production and three key environmental variables—landscape openness, grassland biodiversity and greenhouse gas (GHG) emissions—in three marginal agricultural regions in Sweden. Methods: We do this by first dividing the population of farms in each region into types, based on their land-use and livestock holdings using an innovative clustering method. Thereafter we analysed changes in production activities for farm types over time and evaluated the environmental and food-production impacts, where landscape openness is quantified using a novel indicator. Results and conclusion: Our results show that there is not one single farm type that would simultaneously maximize food production, grassland biodiversity, and landscape openness, whilst minimizing GHG emissions. However, there exists considerable potential to manage the trade-offs between food production and these environmental variables. For example, by reducing land use for dairying and instead increasing both cropping for food production and extensive livestock grazing to maintain landscape openness and biodiversity-rich semi-natural pastures, it would keep food production at similar levels. Significance: Our farm typology allows us to assess the multifunctionality of farming, by relating contrasting production activities to multiple ecosystem services, grassland biodiversity and GHG emissions for informing policy towards more sustainable agriculture. We have demonstrated this with examples under Swedish conditions, but it should to a large extent also be applicable for other countries.

The potential for indirect effects between co-flowering plants via shared pollinators depends on resource abundance, accessibility and relatedness
- 2014

Tidskriftsartikel (refereegranskat)abstract
- Co-flowering plant species commonly share flower visitors, and thus have the potential to influence each other's pollination. In this study we analysed 750 quantitative plant-pollinator networks from 28 studies representing diverse biomes worldwide. We show that the potential for one plant species to influence another indirectly via shared pollinators was greater for plants whose resources were more abundant (higher floral unit number and nectar sugar content) and more accessible. The potential indirect influence was also stronger between phylogenetically closer plant species and was independent of plant geographic origin (native vs. non-native). The positive effect of nectar sugar content and phylogenetic proximity was much more accentuated for bees than for other groups. Consequently, the impact of these factors depends on the pollination mode of plants, e.g. bee or fly pollinated. Our findings may help predict which plant species have the greatest importance in the functioning of plant-pollination networks.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This book is meant as a guide to the evidence available for different conservation interventions and as a starting point in assessing their effectiveness. The assessments are based on the available evidence for the target group of species for each intervention. The assessment may therefore refer to different species or habitat to the one(s) you are considering. Before making any decisions about implementing interventions it is vital that you read the more detailed accounts of the evidence in order to assess their relevance for your study species or system.Full details of the evidence are available at www.conservationevidence.comThere may also be significant negative side-effects on the target groups or other species or communities that have not been identified in this assessment.A lack of evidence means that we have been unable to assess whether or not an intervention is effective or has any harmful impacts.

Farmland Conservation : Evidence for the effects of interventions in northern and western Europe
- 2014
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- This synopsis covers evidence for the effects of conservation interventions for native farmland wildlife. It is restricted to evidence captured on the website www.conservationevidence.com. It includes papers published in the journal Conservation Evidence, evidence summarized on our database and systematic reviews collated by the Collaboration for Environmental Evidence. It is the thrid volume in the series Synopses of Conservation Evidence. Evidence was collected from all European countries west of Russia, but not those south of France, Switzerland, Austria, Hungary and Romania. A list of interventions to conserve wildlife on farmland was developed collaboratively by a team of thirteen experts. A number of interventions that are not currently agri-environment options were added during this process, such as 'Provide nest boxes for bees (solitary or bumblebees)' and 'Implement food labelling schemes relating to biodiversity-friendly farming'. Interventions relating to the creation or management of habitats not considered commercial farmland (such as lowland heath, salt marsh and farm woodland) were removed. The list of interventions was organized into categories based on the International Union for the Conservation of Nature (IUCN) classifications of direct threats and conservation actions. Interventions that fall under the threat category 'Agriculture' are grouped by farming system, with separate sections for interventions that apply to arable or livestock farms, or across all farming types.

Collective Implementation of Ecological Focus Areas : Evaluation of the effects on ecosystem services, agriculture and administration
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Ecosystem services are fundamental to the welfare of mankind, yet these services are often invisible in many social decisions. This report evaluates the effects on the ecosystem services pollination and biological pest control if Sweden were to introduce collective implementation of EFAs as part of the single payment scheme, including quality improvement measures such as establishing flowering plants.The potential environmental effects are seen in relation to the impacts on the economies of farmers and their acceptance of collective implementation, as well as the administrative costs for the authorities. This study is a step towards integrating the value of ecosystem services into decisions in society, something that is to be achieved by 2018 under the milestone targets in Sweden's environmental objectives system.The study that formed the basis of this report was carried out by the Centre for Environmental and Climate Research at Lund University. The work was carried out within the government commission Environmental effects of the CAP. The Swedish Environmental Protection Agency is the primary authority responsible for this report. The Swedish Board of Agriculture, the Swedish National Heritage Board, the Swedish Agency for Marine and Water Management and the County administrative boards also participated in this project.
