  1. 11. Reeling in private governance approaches for sustainable fisheries : A study of Fishery Improvement Projects

    Författare :Sofia Käll; Beatrice Crona; Tracy Van Holt; Tim M. Daw; Andrés Cisneros-Montemayor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : In response to the global fisheries crisis new governance models have been developed. In this thesis, I study one such model, Fishery Improvement Projects (FIPs), that have increased in numbers and importance globally, yet received little scientific attention. LÄS MER

  3. 12. Natural resources and institutional performance : linking social and ecological systems in fisheries

    Författare :Carl Rova; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political Science; Statsvetenskap;

    Sammanfattning : In times of resource scarcity, the management system should be able to adjust, thus enabling it to respond and reorganise when changes in the ecosystem occur. For a successful resource management, ecological resilience must be combined with institutional resilience. LÄS MER

  4. 13. Fish for Food and Ecosystem Function : Fisheries, Trade and Key Ecosystem Processes in Coral Reefs

    Författare :Matilda Thyresson; Magnus Nyström; Edward H. Allison; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fish; food; key ecosystem processes; functional groups; coral reefs; trade; gear; small-scale fisheries; social-ecological systems; Zanzibar; Tanzania; Western Indian Ocean; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Fish is a key source of food and income to millions of people living along tropical coastlines. They also play essential roles underpinning key ecosystem processes in coral reefs. For example, herbivorous fish keep algae in check that otherwise may outcompete corals, reducing the reef’s social-ecological values. LÄS MER

  5. 14. Contributions to linear discriminant analysis with applications to growth curves

    Författare :Edward Kanuti Ngailo; Martin Singull; Dietrich von Rosen; Anuradha Roy; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns contributions to linear discriminant analysis with applications to growth curves.Firstly, we present the linear discriminant function coefficients in a stochastic representation using random variables from the standard univariate distributions. LÄS MER

  7. 15. Fishing for sustainability : Towards transformation of seagrass-associated small-scale fisheries

    Författare :Sieglind Wallner-Hahn; Maricela de la Torre-Castro; Christina Hicks; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; small-scale fisheries; co-management; social-ecological systems; ecosystem services; institutions; transformation; seagrass meadows; destructive gear; food-web interactions; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Small-scale fisheries employ many millions of people around the world, and are particularly important in developing countries, where the dependency on marine resources is high and livelihood diversification options are scarce. In many areas of the world however, small-scale fisheries are at risk which threatens the food security and wellbeing of coastal people. LÄS MER
