  1. 6. Global trade, food production and ecosystem support : Making the interactions visible

    Författare :Lisa Deutsch; Carl Folke; Karin Limburg; Max Troell; David Waltner-Toews; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; global trade; food production; ecosystem support; resilience; agriculture; ecosystem performance; food consumption; ecological footprint; indicators; aquaculture; agricultural intensification; fishmeal; vulnerability; Sweden; animal feed; critical natural capital; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Modern food production is a complex, globalized system in which what we eat and how it is produced are increasingly disconnected. This thesis examines some of the ways in which global trade has changed the mix of inputs to food and feed, and how this affects food security and our perceptions of sustainability. LÄS MER

  3. 7. Land Use, Freshwater Flows and Ecosystem Services in an Era of Global Change

    Författare :Line Gordon; Carl Folke; David Molden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; freshwater; green water; ecosystem services; integrated water resources management; food production; land use and land cover change; vulnerability; resilience; hydrological cycle; global change; Australia; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The purpose of this thesis is to analyse interactions between freshwater flows, terrestrial ecosystems and human well-being. Freshwater management and policy has mainly focused on the liquid water part (surface and ground water run off) of the hydrological cycle including aquatic ecosystems. LÄS MER

  4. 8. Masking environmental feedback : Misfits between institutions and ecosystems in Belize and Thailand

    Författare :Miriam Huitric; Carl Folke; Nils Kautsky; Juan Carlos Castilla; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine reserves; ecosystem change; sequential exploitation; pathology of resource use; institutions; driving forces; coral reefs; social-ecological systems; mangroves; aquaculture; Belize; Thailand; Maine; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The thesis analyses relationships between ecological and social systems in the context of coastal ecosystems. It examines human impacts from resource extraction and addresses management and governance behind resource exploitation. LÄS MER

  5. 9. Man, murres and modern fisheries : A case study in the Baltic Sea

    Författare :Martina Kadin; Henrik Österblom; Olof Olsson; Carl Folke; Morten Frederiksen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seabirds; ecosystem dynamics; fisheries; indicators; ecosystem services; Baltic Sea; common murre; common guillemot; Uria aalge; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Overfishing and climate change put increasing pressure on marine systems, with effects on commercially targeted fish and top predators dependent on these resources. To achieve sustainable resource use, governance mechanisms need to incorporate knowledge about ecosystem dynamics. LÄS MER

  7. 10. Rethinking Urban Nature : Maintaining Capacity for Ecosystem Service Generation in a Human Dominated World

    Författare :Jakob Lundberg; Thomas Elmqvist; Carl Folke; Johan Colding; Steven N. Handel; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Human action has transformed the major part of the Earth’s ecosystems. A growing human population puts further pressure on dynamic landscapes and resources. Crucially, for the first time in history, most people live in cities and environmental change has become truly global. LÄS MER
