  1. 21. Exploring synergies – management of multifunctional agricultural landscapes

    Författare :Lovisa Nilsson; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multifunctionality; ecosystem services; functional biodiversity; agri-environmental policy; CAP; agri-environmental measures;

    Sammanfattning : AbstractHuman ingenuity and activities have resulted in erosion of ecosystems and their capacity to support the sustainable production of goods and functions that we depend on. Biodiversity i.e. LÄS MER

  3. 22. From Vision to Action- Advancing green qualities in local planning practice

    Författare :Sara Khoshkar; Berit Balfors; Monica Hammer; Sara Borgström; Fabiano Lemes de Oliveira; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Municipal planning; strategic environmental assessment; governance; ecosystem services; planning practice; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Biodiversity and ecosystem services have been negatively affected as a result of urbanization. Agenda 2030 emphasizes that biodiversity and ecosystem services issues are important for all Sustainable Development Goals and that measures are needed to reverse the negative trend. LÄS MER

  4. 23. Biodiversity in Agricultural Landscapes: Landscape and Scale-Dependent Effects of Organic Farming

    Författare :Maj Rundlöf; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Natural science; Naturvetenskap; Ekologi; Animal ecology; plants; spatial scales; species richness; Ecology; landscape ecology; agri-environment schemes; farming practice; conservation; butterflies; bumble bees;

    Sammanfattning : Declines in the distribution and abundance of many farmland species during recent decades have been attributed to agricultural intensification. Agri-environment schemes are commonly used in Europe to reduce this loss of farmland biodiversity, but their effectiveness may depend on several external factors. LÄS MER

  5. 24. Grassland restoration : Connectivity, plant community change and cows

    Författare :Rozália E. Kapás; Sara Cousins; Adam Kimberley; Lars A. Brudvig; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; biodiversity; colonization; connectivity; dispersal; distance to species pool; diversity; grassland restoration; grassland specialist species; grazing livestock; habitat availability; plant community composition; restoration; semi-natural grassland; species richness; naturgeografi; Physical Geography;

    Sammanfattning : The ecological significance of semi-natural grasslands is high because these habitats provide a home for a diverse flora and fauna and support a range of associated ecosystem services. Due to large-scale land-use changes the extent of grassland habitat has declined. LÄS MER

  7. 25. Natural enemies: Functional aspects of local management in agricultural landscapes

    Författare :Helena Hanson; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Agricultural intensification; sustainable agriculture; land use; management intensity; landscape scale; ecosystem services; biological control; species trait; pesticides; predatory arthropods; parasitoids; pollen beetles;

    Sammanfattning : Agricultural intensification has raised the global food production but also caused major concerns about environmental and health effects, including contamination by pesticides. Pesticide applications may induce toxicity not only on the target pest species but especially on non-target species. LÄS MER
