  1. 1. Effective soil organic carbon monitoring in perennial agriculture systems - Sampling protocol development and evaluation

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

    Författare :Maja Holm; [2024]
    Nyckelord :Physical geography; ecosystem science; soil organic carbon; soil sampling; perennial crops; carbon sequestration; carbon farming; Kernza™; soil organic carbon stock; Earth and Environmental Sciences;

    Sammanfattning : Perennial agriculture systems are gaining ground as a more sustainable alternative to conventional annual agriculture, partly for their potential to increase the soil organic carbon (SOC) content. Carbon farming is another hot topic for SOC sequestration, as it creates economic incentives for farmers. LÄS MER

  3. 2. Greenhouse gas emissions from peat soil thawing in spring : a comparison between fertilized and unfertilized soil

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Fanny Otterlin Karlsson; [2024]
    Nyckelord :agricultural soil; carbon dioxide; freeze-thaw cycles; nitrous oxide; soil temperature; water content;

    Sammanfattning : Peat soils drained for agriculture and forestry contribute to a significant amount of greenhouse gas emissions. Nitrous oxide is a greenhouse gas with high warming potential and agriculture in general accounts for about 70 % of nitrous oxide emissions. LÄS MER

  4. 3. Can blue mussel shells be used for retrospective 14C-analysis in the marine environment of nuclear power plants?

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Sofia Bjarheim; [2024]
    Nyckelord :Radionuclide; Marine Environment; Blue Mussels; 14C; Nuclear Power Plant; Physics and Astronomy;

    Sammanfattning : Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. LÄS MER

  5. 4. Influence of different carbon sources on methane fluxes in sediments of eelgrass beds and unvegetated areas: a case study on the Swedish west coast

    Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Hampus Holmberg; [2023-06-22]
    Nyckelord :;

    Sammanfattning : One of the best ways to mitigate climate change is through natural carbon sequestration. An efficient way to mitigate climate change is through carbon sequestration from coastal habitats. LÄS MER

  7. 5. Sustainability education in early childhood: Preschool teachers´perceptions and approaches in nurturing sustainability education practises

    Master-uppsats, Göteborgs universitet/Institutionen för didaktik och pedagogisk profession

    Författare :Rose Anyanwu; [2023-01-25]
    Nyckelord :Education; Sustainability; Sustainable Development SD ; Education for Sustainable Development ESD ; Early Childhood for Sustainable Education; Preschool teachers;

    Sammanfattning : Aim: This study aims to examine early childhood teachers’ perceptions of Education for Sustainable Development as well as their pedagogical approaches for nurturing sustainability in Swedish preschools, and how their perceptions of ESD relate to their teaching strategies in nurturing sustainability education. Theory: Lev Vygotsky’s social constructivism emphasizes the significance of language and thought, social interaction, zone of proximal development, scaffolding, mediation, and collaborative work in learning.
