  2. 16. Colonised Coasts : Aquaculture and Emergy Flows in the World System: Cases from Sri Lanka and the Philippines

    Author : Daniel A. Bergquist; Lennart Strömquist; Clas Lindberg; Torbjörn Rydberg; Aida Aragao-Lagergren; Örjan Sjöberg; Uppsala universitet; []
    Keywords : Social and economic geography; Aquaculture; Capitalism; Socio-economic effects; Environmental effects; Benefit distribution; Sustainability; Sustainability assessment; Fairness; Development; Interdisciplinary; Transdisciplinary research; Geography; Emergy; World System Theory; General Systems Theory; Sustainable development; Sri Lanka; Philippines; Kulturgeografi;

    Abstract : This thesis conceives aquaculture as a transfer of resources within and between different parts of the world system. It is argued that due to inappropriate human-nature interactions, resources tend to flow from the South to the North, as a process of coastal colonisation. READ MORE

  4. 17. Of Mangroves and Middlemen : A study of social and ecological linkages in a coastal community

    Author : Beatrice Crona; Patrik Rönnbäck; Nils Kautsky; Neil Adger; Stockholms universitet; []
    Keywords : mangroves; restoration; ecosystem goods and services; natural resource management; local ecological knowledge; social networks; social-ecological systems; East Africa; co-management; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis studies some of the links between the social and ecological components in a coastal Social-Ecological System (SES) of East Africa to gain insight into factors affecting natural resource management at a community level. It does so by assessing the return of ecosystem goods and services in restored mangroves through both ecological and socio-economic measurements, and by empirically studying variations and diversity in content of local ecological knowledge among resource users, its relation to valuation of ecosystem goods and services and its distribution across a social network.

    Abstract : Over time, the Baltic Sea has been contaminated by increasing discharges of pollutants from human activities. Persistent organic pollutants (POPs) have caused toxic effects in wildlife and excess of nutrients have led to eutrophication. READ MORE

  7. 20. Use of Recombinant Allergens for Component-Resolved Diagnostics (CRD) in IgE-Mediated Allergy

    Author : Åsa Marknell DeWitt; Pia Ek; Jonas Lidholm; Ronald van Ree; Uppsala universitet; []
    Keywords : Biomedical laboratory science; recombinant allergen; IgE; component-resolved diagnostics; CRD; tropomyosin; Phl p 11; Phl p 4; Pen a 1; Hev b 5; Biomedicinsk laboratorievetenskap;

    Abstract : Immunoglobulin E (IgE)-mediated allergy occurs when our immune system causes a reaction to otherwise harmless substances (allergens). Allergens are predominantly proteins present in biological materials such as pollens, mites, animal epithelia, moulds and foods. READ MORE
