  1. 11. Sustainable agriculture : From global challenges to local land management

    Författare :John Livsey; Stefano Manzoni; Steve Lyon; Esteban Jobbágy; Stockholms universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; agriculture; irrigation; nutrients; soil properties; water management; fertilisation; Physical Geography; naturgeografi;

    Sammanfattning : Despite the success of agriculture management practices in increasing the availability of food needed to meet the requirements of the expanding global population, there are increasing demands placed on the resources on which the sector depends. Opportunities for the development of agricultural systems are constrained by increasing competition, from other sectors, for shared resources. LÄS MER

  2. 12. Managing sea cucumber fisheries and aquaculture : Studies of social-ecological systems in the Western Indian Ocean

    Sammanfattning : Collecting sea cucumbers to supply the high value Chinese dried seafood market is a livelihood activity available to many people in the Western Indian Ocean (WIO), making it an important part of local economies. These fisheries are generally not successfully managed and tropical sea cucumber fisheries show continuing signs of decline. LÄS MER

  3. 13. Global patterns of international fisheries conflict

    Författare :Jessica Spijkers; Henrik Österblom; Matthew Osborne; Tiffany Morrison; Graeme S. Cumming; Geoff Dabelko; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fisheries; conflict; environmental security; social-ecological systems; complex adaptive systems thinking; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Are international conflicts over fishery resources a growing security concern? High-profile incidences of conflict, diminishing fishery resources and climate impacts on marine systems have made the international community increasingly wary of fisheries conflict. However, we lack knowledge on conflict incidences over time, as well as the contexts in which the conflicts occur, to assess if fisheries conflict is a growing security threat. LÄS MER

  4. 14. Broadening the perspective on seafood production: Life cycle thinking and fisheries management

    Författare :Sara Hornborg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LCA; Nephrops; fuel use; Eastern Baltic cod; fisheries management; threatened species; trophic indicators;

    Sammanfattning : Decisions made by fisheries managers strongly influence the overall resource use and environmental impacts associated with the seafood product from capture fisheries. These findings come from Life Cycle Assessments (LCA), a method that aims at quantifying all relevant resource use and environmental impacts throughout the life cycle of a product. LÄS MER

  5. 15. Barriers and bridges for intensified wood production and biodiversity conservation in NW Russia's boreal forest

    Författare :Vladimir Naumov; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Wood production and biodiversity conservation are two key objectives of sustainable forest management policy. These goals are rival and, therefore, hard to achieve at the same time and space. LÄS MER
