  1. 16. Social diversity for ecosystem management in La Palma Biosphere Reserve, Canary Islands : Perspectives, knowledge and management practices among local stewards in the near-shore marine ecosystem

    Master-uppsats, Stockholms universitet/Stockholm Resilience Centre

    Författare :Laia d'Armengol i Catà; [2013]
    Nyckelord :adaptive co-management; local stewards; La Palma; biosphere reserve; social diversity; local ecological knowledge; local management practices; social networks; mental models.;

    Sammanfattning : Adaptive approaches to ecosystem management emphasize that ecosystems need to be treated as complex social-ecological systems. Furthermore, both ecological and social diversity need to be enhanced to improve the adaptability of such systems to surprises. LÄS MER

  3. 17. Determining the depth of magma storage by investigation of samples from the eruption on La Palma 1971

    Kandidat-uppsats, Institutionen för geovetenskaper

    Författare :Anna Svensson; [2013]
    Nyckelord :canary islands; volcanism; magma storage;

    Sammanfattning : The Canary islands are formed by a slow moving hotspot, from Fuerteventura 20 Ma to el Hierro 1.2Ma years old and La Palma is in the shield building stage of evolution. La Palma had its last eruption 1971 and has had seven eruptions since 1430, which makes it the most active of the islands in our times. LÄS MER

  4. 18. Disintegration and Devolatilisation of Sandstone Xenolith in Magmatic Conduits: an Experimental Approach

    Kandidat-uppsats, Berggrundsgeologi

    Författare :Sylvia Berg; [2010]
    Nyckelord :xenolith; melting; bubbles; gas migration; crustal volatiles; magma-crust interaction; magma volatile budget; explosive eruption;

    Sammanfattning : Xenoliths preserve evidence of magma-crust interactions in magmatic reservoirs and conduits. They reveal processes of partial melting of country rock, and disintegration into magma. Widespread evidence for frothy xenoliths in volcanic deposits exists, and these evidently indicate processes of gas liberation, bubble nucleation and bubble growth. LÄS MER

  5. 19. Välkommen till Kanarieöarna. Våldsam skillnadspolitik i bemötandet av turister och båtflyktingar

    Kandidat-uppsats, Malmö högskola/Fakulteten för kultur och samhälle (KS)

    Författare :Hanna Lindskog; [2009]
    Nyckelord :skillnadspolitik; båtflyktingar; turister; Kanarieöarna; uteslutning; uppdelning; våld; Galtung;

    Sammanfattning : This is a qualitative case study about tourists and boat migrants in movement to and in place on the Canary Islands, Spain. The aim is to study how these two groups of guests are treated differently, either as guests or strangers, based on how they move, illegally or legally, where they come from and where they have rights to go.

  7. 20. A geochemical characterization of the lower part of the Miocene shield-building lavas on Gran Canaria

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Romina Peetz; [2009]
    Nyckelord :Gran Canaria; shield-building lavas; Güigüi Formation; Earth and Environmental Sciences;

    Sammanfattning : Ocean islands offer a great potential to provide information about mantle processes and the composition of the mantle. Gran Canaria is located in the centre of the Canary Island Archipelago and is well suited for such studies. A comprehensive study of the lower Miocene shield-building lavas is performed for this thesis. LÄS MER
