  1. 21. Decision Support Model for a Sustainable Regional Water Supply

    Författare :Karin Sjöstrand; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multi-criteria decision analysis; inter-municipal cooperation; drinking water supply; cost-benefit analysis; decision support; regionalization; sustainability; economic valuation;

    Sammanfattning : Water supply provision has traditionally been a municipal responsibility. However, environmental, social and economic drivers are now making it more attractive to manage the water services in a more aggregated way. LÄS MER

  3. 22. Sustainable agriculture : From global challenges to local land management

    Författare :John Livsey; Stefano Manzoni; Steve Lyon; Esteban Jobbágy; Stockholms universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; agriculture; irrigation; nutrients; soil properties; water management; fertilisation; Physical Geography; naturgeografi;

    Sammanfattning : Despite the success of agriculture management practices in increasing the availability of food needed to meet the requirements of the expanding global population, there are increasing demands placed on the resources on which the sector depends. Opportunities for the development of agricultural systems are constrained by increasing competition, from other sectors, for shared resources. LÄS MER

  4. 23. Fruit tree-based agroforestry on sloping uplands in northwest Vietnam: Effects on soil conservation, tree-crop performance and weed management

    Författare :Hung Do Van; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : On sloping land, agroforestry can be a more sustainable way to produce food andother products and services than sole-crop cultivation of crops. This thesis examinedwhether fruit tree-based agroforestry on smallholder farms on sloping uplands canhave a positive impact on sustainability. LÄS MER

  5. 24. Ammonia sanitisation of human excreta : treatment technology for production of fertiliser

    Författare :Annika Nordin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Safe reuse of plant nutrients from human excreta increases the sustainability of society and promotes health, both by decreasing disease transmission and by increasing agricultural production. This thesis examined ammonia sanitisation as a treatment method to produce a hygienically safe fertiliser from source-separated urine and faeces. LÄS MER

  7. 25. Plant resistance ecology - the role of resistance in plant-insect mutualisms

    Författare :Daniela Weber; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Global food security is largely dependent on the use of synthetic pesticides for pest control. This extensive reliance on pesticides, however, has promoted widespread loss of insect diversity; thereby jeopardizing the provision of insect ecosystem services like pollination and biological control.
