  1. 1. Ecosystem services from woody vegetation in East African rangelands

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Anna Linnéa Elisabeth Swärd; [2023]
    Nyckelord :dryland ecosystems; rangelands; rangelands; woody vegetation; restoration; Karamoja; West Pokot; pastoralists; agro-pastoralists; East Africa;

    Sammanfattning : Drylands cover nearly half of the Earth's land surface and are dominated by croplands and rangelands. Dryland ecosystems worldwide are affected by land degradation. Increased population pressure, climate change and unsustainable land use threaten essential ecosystem services and adversely impact people’s livelihoods and well-being. LÄS MER

  3. 2. Drivers and Barriers for Biochar Deployment in Swedish Agriculture : a Multi-Level Perspective on Sustainability Transitions

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Danielle Jansen; [2023]
    Nyckelord :Agriculture; Socio-technical transitions; Multi-level perspective;

    Sammanfattning : There are several sustainability challenges (e.g., environmental degradation, biodiversity loss, and food insecurity) that agro-food systems face. Simultaneously, agriculture is a major contributor to greenhouse gas emissions. LÄS MER

  4. 3. Assessing the Impacts of Climate Change and Water Scarcity on Agricultural Practices in Kenya -Implications for Adaptation Strategies

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

    Författare :Sanjina Rahi Oishee; [2023]
    Nyckelord :Climate Change; Agriculture; Temperature; Precipitation; Water Scarcity; Agro-Climatic Zone; Earth and Environmental Sciences;

    Sammanfattning : Like other African countries, Kenya’ economy and food security is heavily dependent on agriculture. Climate change has led to variability in temperature and precipitation, and extreme weather events such as droughts and floods, all of which can significantly impact crop productivity and food security in the long-term.

  5. 4. Urea-Based Treatments of Unretted Hemp Fibres from Residual Streams

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Danilo Esteban Ortiz Sarasty; [2023]
    Nyckelord :Finola waste; stalks; unretted hemp fibres; degumming; cold urea alkali; microwave-urea;

    Sammanfattning : More sustainable and efficient degumming methods are required to extract finner bast fibres, especially from agro-industrial waste streams such as stalks from hemp for food purposes. For this reason, in this study, two urea-based treatments were evaluated as degumming alternatives for unretted hemp fibres from residual streams, one at cold and alkaline conditions (CUA) and the other in combination with microwave radiation (MWU).

  7. 5. The sources and dynamics of technological change in cassava farming in Ghana

    Master-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Chekhros Kilichova; [2023]
    Nyckelord :Ghana; cassava; technology adoption; agricultural transformation; farm size; agricultural extension service; Business and Economics;

    Sammanfattning : Farm size expansion in some countries in Sub-Saharan Africa, including in Ghana, is a recent phenomenon, and is indicative of the agricultural transformation process taking place in the region. Technology use and adoption level is an integral and complex part of this process, which is studied in relation to the expanding farm sizes and agricultural transformation in this study. LÄS MER
