  1. 16. Change for sustainable agricultural business. Addressing business model transformation and sustainable value creation

    Författare :Vera Sadovska; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Society is facing global challenges, such as poverty and climate change, that affect entire ecosystems and human communities. Many sustainability challenges arise from existing production and consumption patterns, and thus many believe that business transformation to sustainability is essential to solving global socio-ecological problems.

  3. 17. Earthworm and arbuscular mycorrhizal communities in agricultural soils : management of key soil organisms for sustainable agriculture

    Författare :Kaisa Torppa; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Intensive agriculture is detrimental to soil biodiversity and functioning. Promoting communities of key soil organisms, such as earthworms and arbuscular mycorrhizal (AM) fungi, may help improve agricultural sustainability by replacing inputs with ecosystem services. LÄS MER

  4. 18. Towards sustainable livestock systems: Developing and applying methods for broad sustainability assessment of pig and cattle systems

    Författare :Stanley Zira; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Meat and milk are valuable foods from livestock that contribute to quality of life for humans but have negative environmental, social and economic impacts. Measuring such impacts in sustainability assessments requires methods with a broad and deep focus. LÄS MER

  5. 19. Nutrient economy in annual and perennial crops : comparisons between and within crop species in a sustainability context

    Författare :Fereshteh Pourazari; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Nitrogen use efficiency (NUE) of agricultural crops is related to crop nitrogen (N) uptake and thereby the amount of N that is removed from agro-ecosystems through crop harvest. As the N removal through harvest is linked to the fertilization requirements and the risk of N leaching, the crop NUE is an important aspect of sustainability in agriculture. LÄS MER

  7. 20. The Technology and Economy of Farm-Scale, High-Solids Anaerobic Digestion of Plant Biomass

    Författare :Mattias Svensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; farm-scale; Bioteknik; farmhouse construction; Lantbruksteknik; Biotechnology; agricultural machines; kontroll av utsläpp; Agricultural engineering; Miljöteknik; pollution control; Environmental technology; Lantbruksekonomi; straw bed priming; stratified bed digesters; nitrogen recycling; greenhouse gases; Sweden; Agricultural economics; sequential single-stage fed-batch; ley crops; sustainability; wheat straw; sugar beet tops; crop residues; high-solids; economy; Anaerobic digestion; biogas upgrading;

    Sammanfattning : Anaerobic digestion is a microbially mediated process occurring in nature in the absence of oxygen and other non-carbonaceous electron acceptors. The majority of the carbon of the organic matter degraded in the process is transformed into carbon dioxide and methane. LÄS MER
