  1. 16. Supply and value chain analyses of warqe food products in relation to post-harvest losses

    Författare :Ashenafi Chaka Tuffa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Post-harvest losses are a global problem and are of critical importance in food-insecure countries such as Ethiopia. Losses of root and tuber crops are known to be high in developing countries, where many of the population are dependent on these crops. Warqe (Ensete ventricosum (Welw.) Cheesman) is a staple crop in Ethiopia. LÄS MER

  3. 17. Of seagrass and society : Exploring contributions of tropical seagrass meadows to food security

    Författare :Benjamin Jones; Johan S. Eklöf; Lina M. Nordlund; Leanne C. Cullen-Unsworth; Richard K.F. Unsworth; Maricela de la Torre-Castro; Christina Hicks; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biodiversity; Blue food; Food security; Social-ecological systems; Small-scale fisheries; Seagrass meadows; marinbiologi; Marine Biology;

    Sammanfattning : Conserving biodiversity while simultaneously feeding a growing population is one of the grand challenges of the Anthropocene. Recently, global assessments have shone a light on the importance of the marine environment for the supply of food (often termed blue food), as well as the diverse and many livelihood opportunities associated to it.

  4. 18. ‘Less But Better’ Meat for Food System Sustainability - Exploring Meanings & Characterisations

    Författare :Kajsa Resare Sahlin; Line Gordon; Annika Carlsson-Kanyama; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ‘less but better’ meat; livestock; food system sustainability;

    Sammanfattning : Livestock systems are key drivers behind a range of pressing sustainability issues; but with that, also present central opportunities for leveraging positive food system change. The aim of this thesis is to contribute to increased understanding of what more sustainable meat production and consumption is, using ‘less but better’ as a framework. LÄS MER

  5. 19. Some Fluid Dynamic Characteristics in the Scale-up of Rushton Turbine-Agitated Tanks

    Författare :Eva Ståhl Wernersson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; Rushton turbine; turbulent kinetic energy; geometry; local energy dissipation rate; power input; scale-up; anemometry measurements; agitated tanks; turbulence; Kemiteknik och kemisk teknologi;

    Sammanfattning : Turbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. LÄS MER

  7. 20. Land Use, Freshwater Flows and Ecosystem Services in an Era of Global Change

    Författare :Line Gordon; Carl Folke; David Molden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; freshwater; green water; ecosystem services; integrated water resources management; food production; land use and land cover change; vulnerability; resilience; hydrological cycle; global change; Australia; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The purpose of this thesis is to analyse interactions between freshwater flows, terrestrial ecosystems and human well-being. Freshwater management and policy has mainly focused on the liquid water part (surface and ground water run off) of the hydrological cycle including aquatic ecosystems. LÄS MER
