  1. 1. Småbrukbondens förökningsmetoder på Siargao - Traditionellt småbruk på en tropisk ö i Stilla havet, Filippinerna

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Mary Bergenheim; [2023-05-12]
    Nyckelord :traditional knowledge; tacit knowledge; sustainable farming in tropics; propogation;

    Sammanfattning : Several studies and reports regarding traditional knowledge are describing the importance of this knowledge in development of a sustainable farming in the future. Traditional farming is important in sustaining ecosystems and their services as well as the planets biodiversity. LÄS MER

  3. 2. Ecosystems Services in swidden agriculture in the Peruvian tropical Andes : the Kechwa-Lamas farm-forestry system

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Geannine Gisset Chabaneix Portocarrero; [2023]
    Nyckelord :swidden agriculture; ecosystem services; Peru; Amazon;

    Sammanfattning : In the Amazon, life supporting services are importantly associated to forest areas. Nevertheless, the connection of ecosystem services to agricultural systems it is also of great importance, because agriculture is one of the most important causes of degradation and loss of these areas.

  4. 3. Trade-offs between land conservation and agricultural production: Case study of the Spanish Lookout area and the Belize Maya Forest Reserve

    Kandidat-uppsats, Lunds universitet/Sociologi

    Författare :Tomas Castro Rojas; [2022]
    Nyckelord :LULUCF; agriculture; deforestation frontiers; remote sensing; biodiversity; Social Sciences;

    Sammanfattning : Habitat destruction (evidenced in land use change) represents one of the biggest threats to environmental resources and biodiversity. In the tropics, this threat is maximized as deforestation frontiers have expanded into natural ecosystems at increasing rates over the last decades for agricultural cropping and livestock husbandry.

  5. 4. Intercomparison of a Dynamic Ocean for Earth-like Aqua-planets

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Fredrik Plane; [2022]
    Nyckelord :Astrobiology; Planets; Aqua-planets; Atmosphere and Ocean physics; Exoplanet; Habitability; General Circulation Model; GCM; Climate Modelling; Dynamic Ocean;

    Sammanfattning : I present herein an ensemble of ROCKE-3D aqua-planet simulations which I compare with the simulations presented in the work of Yang et al. (2019) and other similar works. The focus was on contrasting differences in the greenhouse effect between the models. LÄS MER

  7. 5. The Biogeographical Extent and Global Synchronicity of the Late Miocene Reticulofenestra pseudoumbilicus Paracme

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Joseph Asanbe; [2022]
    Nyckelord :late Miocene; biogenic bloom; nannofossil biostratigraphy; paleo-productivity; Reticulofenestra size variation;

    Sammanfattning : Previous biostratigraphic studies in the Indian Ocean, equatorial Pacific, Atlantic Ocean and the Caribbean Sea document the temporal disappearance of Reticulofenestra pseudoumbilicus in the late Miocene (Tortonian age). This interval has been subsequently defined as the R. pseudoumbilicus paracme. LÄS MER
