  1. 11. An investigation of pea and cereal varieties for organic intercropping in Sweden

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Agnes Elise Matilda Wilson; [2024]
    Nyckelord :Intercropping; agroecology; organic; peas; cereals; heritage grains;

    Sammanfattning : Organic farming, intercropping and the conservation of landraces are agroecological methods of transitioning to a more sustainable and resilient agricultural system, however there is a lack of data on varieties suitable for organic intercropping. Therefore, two spatially parallel field trials were conducted with 11 pea varieties intercropped with oat, and 38 varieties of cereals (wheat, oat, and barley), in sole crops. LÄS MER

  3. 12. Shifting focus from yields to food supply : an evaluation of the ‘number of people fed per hectare’ indicator at farm and national level

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Ida Ekqvist; [2024]
    Nyckelord :Land use efficiency; Sustainability indicators; Agricultural productivity; Food production;

    Sammanfattning : The challenge of feeding a growing global population while reducing the pressure on climate and ecosystems has gained much attention in research over the last decades. A crucial yet often overlooked aspect in research addressing this complex challenge is the efficiency of food production in meeting nutritional needs within the constraints of global cropland resources.

  4. 13. Diving Deep: Seabird foraging tactics and local prey field

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Elin Andersson Sjöholm; [2024]
    Nyckelord :Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Sammanfattning : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. LÄS MER

  5. 14. Techno-Economic Analysis of Dye Separation in Textile Recycling

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :David Lundberg; [2024]
    Nyckelord :Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Sammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER

  7. 15. Orsaker till och åtgärder för att förbättra ekonomin i förstagallringar på Åland

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Robert Hellgren; [2024]
    Nyckelord :förstagallring; ekonomiskt utfall; Åland;

    Sammanfattning : Röjningsbehovet på Åland är stort och andelen eftersatta ungskogar ökar för varje år. Det ekonomiska utfallet i förstagallringar är väldigt dåligt och i många fall obetydlig, vilket gör att intresset för att röja är litet. Det leder många gånger till att ungskogarna röjs för sent och ibland uteblir röjningen helt. LÄS MER
