  1. 1. 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.

  3. 2. Integrating Waste Heat from Hydrogen Production Into District Heating

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fawzi Kayali; [2023]
    Nyckelord :Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

    Sammanfattning : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. LÄS MER

  4. 3. Students’ perceptions of genetically modified organisms : what is required to increase acceptance?

    Master-uppsats, SLU/Dept. of People and Society

    Författare :Emma Lif; [2023]
    Nyckelord :Genetically modified organisms; perceptions; acceptance; students; qualitative semi-structured interviews;

    Sammanfattning : Producing enough food for the world's growing population is a challenge that puts great pressure on the agricultural food system to ensure global food security Furthermore, climate change is additionally exacerbating this challenge. Part of the solution could be genetically modified organisms (GMOs), but their use has been a source of controversy among various actors that have hindered their adoption. LÄS MER

  5. 4. Shortening the chains : social relations and dynamics of production in Uppland's alternative food networks

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

    Författare :Eleni Katsika; [2023]
    Nyckelord :alternative food networks; food commoning; dynamics of production; political ecology; social relations; Sweden;

    Sammanfattning : Current global food systems are characterised by a highly concentrated capitalist market where food is treated as a globalised hyper commodity and small-scale farmers are pushed into the side-line. The need for the transformation of that food system is urgent and acknowledged worldwide. LÄS MER

  7. 5. Cultivating Resilient Local Food Systems: Identifying opportunities and strategies for sustainable public procurement

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Madison Sherwood-Walter; [2023]
    Nyckelord :Sustainable Development; Local Food Systems; Public Procurement; Innovation; Agricultural Policy; Rural Development;

    Sammanfattning : The industrialization of the global food system has drastically altered agricultural practices, transitioning from small-scale, subsistence farming to large-scale, transnational supply chains dominated by agribusinesses. While this shift has increased productivity, it has led to environmental degradation, economic inequity, and loss of traditional agricultural knowledge. LÄS MER
