  1. 1. Sustainable agriculture : From global challenges to local land management

    Författare :John Livsey; Stefano Manzoni; Steve Lyon; Esteban Jobbágy; Stockholms universitet; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL 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. 3. Historical Urban Agriculture : Food Production and Access to Land in Swedish Towns before 1900

    Författare :Annika Björklund; Mats Widgren; Johannes Renes; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban agriculture; urban history; urban geography; Sweden; town; food production; food consumption; Uppsala; historical geography; land allocation; cadastral maps; urban land-use; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

    Sammanfattning : This doctoral thesis analyses the role of historical urban agriculture in a long-time perspective, through a combination of overarching surveys of Swedish towns and detailed studies of one town – Uppsala in east-central Sweden. The study shows how agricultural land – town land – of various sizes was donated to towns repeatedly during medieval times and in the 16th and 17th centuries. LÄS MER

  5. 4. Land-Use and Climate Effects of Bioenergy: Carbon balances of Swedish forest bioenergy systems – and – Geospatial biomass supply-and-demand matching for Europe

    Författare :Olivia Cintas Sanchez; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; GIS; EU; bioenergy; Sweden; agriculture; residues; Forestry; climate change; GHG balances;

    Sammanfattning : In order to keep global warming below 2 degrees Celsius, greenhouse gas emissions have to be drastically reduced. Bioenergy can play a role in climate change mitigation by substituting for energy from fossil fuels; however, biomass is a limited resource associated with emissions from land use and land-use change.

  7. 5. Felling Forests from Afar: Quantifying Deforestation Driven by Agricultural Expansion and International Trade

    Författare :Florence Pendrill; Chalmers University of Technology; []
