  1. 1. Microalgal solutions in Nordic conditions : industries transition toward resource recovery?

    Författare :Lina Mattsson; Catherine Legrand; Elin Lindehoff; Hanna Farnelid; Kristian Spilling; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microalgae; algal cultivation; polyculture; resource recovery; seasonal variation; industrial partnership; CO2 mitigation; nitrogen removal; community composition; Ecology; Ekologi; Environmental Biotechnology; Miljöbioteknik; Miljövetenskap; Environmental Science; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology;

    Sammanfattning : Microalgal solutions can through photosynthesis recover greenhouse gas (CO2) and nutrients from industrial waste, reducing climate footprint and eutrophication. An added value to the process is algal biomass containing lipids, proteins, and carbohydrates with commercial potential for biofuel, feed, and fertilizer. LÄS MER

  3. 2. Colonised Coasts : Aquaculture and Emergy Flows in the World System: Cases from Sri Lanka and the Philippines

    Författare :Daniel A. Bergquist; Lennart Strömquist; Clas Lindberg; Torbjörn Rydberg; Aida Aragao-Lagergren; Örjan Sjöberg; Uppsala universitet; []

    Sammanfattning : This thesis conceives aquaculture as a transfer of resources within and between different parts of the world system. It is argued that due to inappropriate human-nature interactions, resources tend to flow from the South to the North, as a process of coastal colonisation. LÄS MER

  4. 3. Ecosystem processes and biodiversity : theoretical studies and experiments with an aquatic model ecosystem

    Författare :Jon Norberg; Michael L Pace; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Systems Ecology; systemekologi;

    Sammanfattning : Today, human enterprise has implications for all of nature, from the well being of the smallest organism, to the alteration of global biogeochemical cycles. To understand how major ecosystem processes are affected by environmental changes and decreasing biodiversity is crucial as many of natures services depend of such processes. LÄS MER

  5. 4. Sowing the Seeds of Change : Entrepreneurial Practices in a North-South Collaboration on Pemba Island from a Structuration Perspective

    Författare :Alina Husung; Malin Tillmar; Richard Ferguson; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social entrepreneurship; entrepreneuring; structuration theory; sustainability; Global North-Global South partnership; East Africa; climate change; Business administration; Företagsekonomi;

    Sammanfattning : This dissertation aims to expand our understanding of social entrepreneuring on the micro- and meso-levels in the Global South. The study employs structuration theory by Giddens to explore how social entrepreneurs in a North-South collaboration engage in everyday practices that aim to affect socio-ecological regenerative change.
