  1. 1. Salt tolerant horticultural plants to save freshwater usage

    Kandidat-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Tsun-Ya Chuang; [2024]
    Nyckelord :climate change; freshwater scarcity; halophyte; salt tolerance; bonsai;

    Sammanfattning : As freshwater becomes scarce worldwide due to climate change and population increases, there is an urgent need to develop innovative approaches to address the issue of reducing freshwater consumption. Selecting species with high ornamental value and salt tolerance for use as green hedges or bonsai in urban or coastal areas could be a strategic approach for promoting greening and maintaining water resource sustainability.

  3. 2. Wells of Conflict : A Qualitative Study on How Groundwater Scarcity Affects Communal Conflict

    Kandidat-uppsats, Uppsala universitet/Institutionen för freds- och konfliktforskning

    Författare :Rebecca Ander; [2024]
    Nyckelord :Groundwater; Water Scarcity; Communal Conflict; Ethnic Conflict; Kenya;

    Sammanfattning : The topic of whether resource scarcity affects conflict has for long been debated in the field  of peace and conflict studies. This study aimed to understand if there is a correlation between groundwater scarcity and communal conflict by answering the research question ‘How does groundwater scarcity affect communal violence in the Arid and Semi-Arid Land of Kenya’.

  4. 3. Sustainable use of calcium nitrate fertilizer under variable precipitation, soil properties and crop management

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

    Författare :Liliana Marcela Daza Gomez; [2023]
    Nyckelord :nitrogen.; calcium nitrate; ammonium-based fertilizers; urea; nitrate leaching; nitrous oxide emissions; crop yield;

    Sammanfattning : Application of nitrogen fertilizers in agriculture contributes substantially to global greenhouse gas emissions and nitrogen leaching. Accordingly, there is a need to increase knowledge about sustainable farming practices to reduce nitrogen losses to the environment without curtailing crop harvest. LÄS MER

  5. 4. The impact of CO2 fertilisation on foliage in West and East Africa

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

    Författare :Gaetane Demyttenaere; [2023]
    Nyckelord :Physical geography and ecosystem analysis; CO2 fertilisation; semi-arid ecosystems; remote sensing; Normalised Difference Vegetation Index; Earth and Environmental Sciences;

    Sammanfattning : Anthropogenic impact on terrestrial ecosystems continues to grow as we further enhance atmospheric Carbon Dioxide (CO₂) concentrations. The changing climatic conditions and direct influence of CO₂ on vegetation has a big impact on ecosystem functions. LÄS MER

  7. 5. Post-Fire Vegetation Recovery Monitoring using MODIS Time Series: A Case Study in California

    Kandidat-uppsats, KTH/Geoinformatik

    Författare :Julia Edje; [2023]
    Nyckelord :vegetation recovery; MODIS; HRT; EVI; fire; burn severity; land cover; climate zone; California;

    Sammanfattning : Human-caused forest fires have increased in magnitude and frequency, affecting global vegetation and requiring a re-evaluation of fire regimes. Changing fire regimes have led to reduced burned areas in fire- dependent ecosystems and increased areas in fire-independent ecosystems, resulting in changes in land cover and posing a threat to native plant communities.
