  1. 1. Grasslands in a changing climate : Summer drought and winter warming effects on grassland vegetation

    Författare :Nina Roth; Sara A. O. Cousins; Carly Stevens; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; climate change; compost; floral resources; grasslands; in-situ experiments; mowing; nectar; open-top chambers; plants; rain-out shelters; sheep grazing; soil amendments; summer drought; winter warming; naturgeografi; Physical Geography;

    Sammanfattning : Grasslands harbour a high biodiversity of both plants and animals, and they provide many ecosystem services such as fodder production, pollination, and carbon storage. Climate change is likely to alter grassland ecosystems, with the effects varying according to the exact nature and timing of changes. LÄS MER

  3. 2. Boreal Forest Wildfire in a Changing Climate

    Författare :Johan Eckdahl; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; boreal forest wildfire; carbon emissions; nutrient cycling; nitrogen; microbial community; plant community; climate chnge; secondary succession; Sweden; Fennoscandia; biodiversity; boreal skogsbrand; koldioxiduttsläpp; näringscykling; kväve; mirkobiellt samhälle; växtsamhälle; klimatförändring; sekundär succession; sverige; Fennoskandien; biologisk mångfald;

    Sammanfattning : The boreal region contains 40% of the earth’s carbon (C) that is stored in vegetation and soils with its forests accounting for almost 30% of the terrestrial C sink. Boreal forests are experiencing some of the most rapid rates of climatic warming and increases in fire activity, threatening to release large amounts of their dense C reserves to the atmosphere.

  4. 3. Sustainable Urban and Regional Development and Related Ecosystem Services and Water-Climate Interactions

    Författare :Jessica Faye Page; Zahra Kalantari; Georgia Destouni; Bev Wilson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; urban planning; regional planning; sustainable cities; nature-based solutions; climate change; planning support systems; sustainable development; naturgeografi; Physical Geography;

    Sammanfattning : To accommodate a growing global population while mitigating climate change, urban areas must grow while minimising environmental impacts. To achieve this, a city must be treated as a complex socio-ecological system in which many actors and subsystems act in unclear and unpredictable ways. LÄS MER

  5. 4. Bridging the floods - The role of social learning for resilience building in urban water services

    Författare :Åse Johannessen; Avdelningen för Riskhantering och Samhällssäkerhet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; urban water services; climate change; adaptation; urban transformation; transition; flood risk management; water resources management; disaster risk reduction; resilience; resilient cities;

    Sammanfattning : The development of cities is increasingly threatened by a worldwide water crisis. Urban water services (including drinking water, sanitation and drainage) are facing complex and multiple pressures, which are becoming increasingly frequent and severe. LÄS MER

  7. 5. Reconnecting with nature through concepts : On the construction of values in the ecosystem services paradigm

    Författare :Sanna Stålhammar; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ekosystemtjänster; hållbarhetsvetenskap; Vetenskapsteori; människa↔natur; värde; Ecosystem Services; Ecosystem services concept; ecosystem services value; Ecosystem service assessment; Cultural ecosystem services; socio-cultural valuation; connectedness; Relational value; experienced and context-based perspective.; Urban green infrastructures;

    Sammanfattning : The alarming rates of extinction and degrading ecosystems call for new means of understanding and accounting for how people depend on nature. Ecosystem services (ES) is a contested but widely applied concept aiming to connect ecosystem functions to human wellbeing and to assess and account for how nature matters in decision-making. LÄS MER
