  1. 11. Restoration of semi-natural grasslands : Impacts on biodiversity, ecosystem services and stakeholder perceptions

    Författare :Emelie Waldén; Regina Lindborg; Sara A O Cousins; Erik Öckinger; Aveliina Helm; Stockholms universitet; []

    Sammanfattning : Humans play a major role shaping the living conditions for not only ourselves, but also all other species on Earth. In fact, some species-rich habitat types require human management to uphold the biodiversity and related ecosystem services. LÄS MER

    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.

  5. 14. Nature, culture, rights : exploring space for indigenous agency in protected area discourses

    Författare :Elsa Reimerson; Camilla Sandström; Ulf Mörkenstam; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Protected areas; conservation; biological diversity; heritage; Indigenous peoples; Indigenous rights; Sami; discourse; postcolonial theory; participation; agency; Skyddade områden; naturvård; biologisk mångfald; världsarv; urfolk; urfolksrättigheter; samer; diskurs; postkolonial teori; deltagande; handlingsutrymme; statskunskap; political science;

    Sammanfattning : There is considerable geographical overlap between areas set aside for nature conservation or protection and Indigenous peoples’ lands, and the social, economic, and political consequences of protected areas have often been extensive for Indigenous peoples. Discourses of conservation converge with discourses of Indigenous peoples, and both carry a legacy of colonial constructs and relationships. LÄS MER

    Sammanfattning : Land use change constitutes a primary driving force in shaping social-ecological systems world wide, and its effects reach far beyond the directly impacted areas. Graph based landscape ecological tools have become established as a promising way to efficiently explore and analyze the complex, spatial systems dynamics of ecological networks in physical landscapes.
