  1. 21. Adaptive capacity for social and environmental change : The role of networks in Chile’s small-scale fisheries

    Författare :Andrés Marín; Beatrice Crona; Nadine Marshall; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; artisanal; benthic; Chile; coastal areas; collaborative management; disasters; ecosystem services; hazards; livelihoods; post-disaster; QCA; recovery; TURFs; Análisis Cualitativo Comparativo; artesanal; bentónico; Chile; desastres; manejo colaborativo; medios de vida; peligros; post desastre; recuperación; servicios ecosistémicos; zonas costeras; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : World’s small-scale fisheries (SSF) face permanent and increasing external changes and shocks that challenge their viability and potential as an engine of human sustainable development. It is broadly assumed and expected that fishers and their communities have the capacity to adapt to current and future social and ecological changes. LÄS MER

  3. 22. Salmonids and grey seals (Halichoerus grypus) : mitigation in pontoon traps

    Författare :Linda Calamnius; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In the 1970’s, the seal populations of the Baltic Sea Area were at historically low levels. They have recovered and increased since then. The increase of the seal populations is a success for the management of the Baltic Sea Area environment. It has also meant an increase in number of interactions with coastal fisheries. LÄS MER

  4. 23. 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. 24. Size Selection of Fish in the Trap Fisheries of the Baltic and Bothnian Seas

    Författare :Mikael Lundin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A sustainable fishery in the Baltic Sea requires fishing gear that fishes selectively and at the same time excludes raiding seals. A successful type of trap recently developed in response to the seal problem is the pontoon fish chamber, which significantly decreases damage to gear and catch losses caused by grey seals. LÄS MER

  7. 25. Managing Mangrove Ecosystem Services for Local Livelihoods and Adaptations in Tanzania

    Författare :Baraka Nyangoko; Håkan Berg; Martin Gullström; Mwita Mangora; Mwanahija Shalli; Johan Hollander; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mangroves; ecosystem services; mangrove management; livelihoods; ecosystem-based adaptation; Tanzania; naturgeografi; Physical Geography;

    Sammanfattning : Recognizing the importance of ecosystem services (ES) for peoples' livelihoods and well-being is important for decision-making processes on conservation. Mangrove ecosystems in Tanzania are protected by law, but they continue to be exposed to degradation and loss, and there is still limited information about the awareness, preferences, status and trends of the ES they provide.
