  1. 1. The environment of conflict. A quantitative analysis of the link between water scarcity, non-state conflict and the quality of government in Africa

    Kandidat-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Monica Berenji; [2021-02-12]
    Nyckelord :Freshwater resources; water scarcity; non-state conflict; impartiality; corruption;

    Sammanfattning : Environmental security has been diligently examined in previous research on both subnational and multinational levels and have not found consensus on the contributing factors for why and how environmental conflict occurs. This thesis aims to contribute to this strand of research, more specifically asking if water scarcities effect the number of non- state conflicts in Africa, depending on the quality of governments.

  2. 2. The hydrodynamic impacts of Estuarine Oyster reefs, and the application of drone technology to this study

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Oskar Evert Johansson; [2021]
    Nyckelord :Geography; Geographical Information Systems; GIS; Physical Geography; Oyster Reef; Drone; UAV; Hydrodynamics; Earth and Environmental Sciences;

    Sammanfattning : The impacts of climate change are being seen within the estuarine environment through erosion and shoreline retreat, associated with sea-level rise and changes in storm activity. Restoration oyster reefs have been identified as a working-with-nature strategy to protect and restore these shoreline environments, stabilising sediment, and reducing erosion. LÄS MER

  3. 3. Blue biotechnology : its role in the future of food

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Andrea Lundh; [2020]
    Nyckelord :Aquaculture; blue biotechnology; aquatic resources; SDG; sustainable development goals; blue growth; zero hunger; food security; agenda 2030;

    Sammanfattning : To provide healthy food and livelihoods to a growing population on Earth, while environmental issues becoming more adverse, as well as climate change becoming more critical, is one of today’s greatest challenges. By 2015 the United Nations come up with 17 Sustainable Development Goals (SDG’s) to tackle global challenges as poverty, global hunger, climate resilience, population growth control, achieving food security, and promotion of sustainable agriculture.

  4. 4. Water Purification : Research on the Energy Supply of Air Gap Membrane Distillation for Access to Clean Water

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik; KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Linda Yang; Robert Liao; [2020]
    Nyckelord :Air gap membrane distillation; water purification; energy system; Vattenrening; energisystem; luftspaltmembran;

    Sammanfattning : Water stress is an ongoing problem in many places in the world, while the demand for clean and safe freshwater is growing due to the increasing population. In many developing countries, water supplies often are contaminated with arsenic, fluoride, etc. LÄS MER

  5. 5. Miljöpåverkan av bioplast från skogsindustriellt avloppsvatten : En jämförande livscykelanalys av polypropen (PP) och polyhydroxyalkanoater (PHA) från Gruvöns massa- och pappersbruk

    Kandidat-uppsats, Karlstads universitet

    Författare :Joakim Eriksson; [2020]
    Nyckelord :life cycle assessment; LCA; bioplastic; forest industrial wastewater; BillerudKorsnäs; Gruvöns bruk; polyhydroxyalkanoates; PHA; livscykelanalys; LCA; bioplast; skogsindustriellt avloppsvatten; BillerudKorsnäs; Gruvöns bruk; polyhydroxyalkanoater; PHA;

    Sammanfattning : I den här studien har en beräkningsmodell byggts för hur PHA skulle kunna produceras av substrat i avloppsvatten från Gruvöns bruk. Därefter har en jämförande livscykelanalys utförts där PP-sugrör inom Europa ersätts med PHA-sugrör från bruket. LÄS MER
