1. 6. Catching values of small-scale fisheries : A look at markets, trade relations and fisher behaviour

   Författare :Elizabeth Drury O'Neill; Beatrice Crona; Tim Daw; Therese Lindahl; Ragnhild Overå; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; small-scale fisheries; value chains; gender; seafood trade; global markets; patron-client; human wellbeing; benefits; markets; local social dynamics; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : This thesis explores small-scale fisheries trade, markets and the accompanying relationships. It does so to understand how they contribute to human wellbeing and ecosystem health through fisher's behaviour in the marine environment. LÄS MER

3. 7. Effects of confinement and initiation delay on fragmentation and waste rock compaction : Results from small scale tests

   Författare :Daniel Johansson; Gideon Chitombo; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Sammanfattning : Sub-level caving (SLC) is classified as a mass mining method and there is an increasing interest in its application worldwide and in a very wide range of geotechnical environments. Design of sub-level blasting rounds and optimization has become more important now when the sizes of the blasting rings have become larger. LÄS MER

4. 8. 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

5. 9. Income diversification as a response to social-ecological traps : A case study of small-scale fisheries and aquaculture in the Tam Giang lagoon, Central Viet Nam

   Författare :Tong Thi Hai Hanh; Wiebren Boonstra; Melissa Marschke; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; alternative livelihoods; aquaculture households; income diversification; fishing households; small-scale aquaculture; small-scale fisheries; social-ecological traps; and Tam Giang lagoon; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

   Sammanfattning : Many small-scale fishing and aquaculture households in the global South struggle with reinforcing feedbacks between resource degradation and livelihood impoverishment – a situation that is often resembled to a social-ecological trap. Studies suggest that facilitation of income diversification contributes to mitigation and even prevention of trap situations as it reduces exploitation pressure while at the same time makes the households’ livelihood more resilient.

7. 10. Learning ecosystem complexity : A study on small-scale fishers’ ecological knowledge generation

   Författare :Diana Garavito-Bermúdez; Camilla Thunborg; Cecilia Lundholm; Beatrice Crona; Alan Reid; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; small-scale fishers; informal learning; knowledge generation; systems thinking; ecological knowledge; ecosystem complexity; work practices; emotional bonds to place; sustainable fisheries management; environmental learning; Vättern; Blekinge; Baltic Sea.; pedagogik; Education;

   Sammanfattning : Small-scale fisheries are learning contexts of importance for generating, transferring, and updating ecological knowledge of natural environments through everyday work practices. The rich knowledge fishers have of local ecosystems is the result of the intimate relationship fishing communities have had with their natural environments across generations (see e. LÄS MER
