  2. 16. Shaping sustainable food systems : Local participation in addressing global challenges

    Author : Aniek Hebinck; Line Gordon; Joost M. Vervoort; Stephan Barthel; Moya Kneafsey; Stockholms universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; food systems; sustainability; food governance; transformative change; participatory processes; participation; civil society; niche level; food policy; urban food; urban agriculture; food poverty; imagined futures; foresight; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : The current unsustainable trajectory of food systems puts the social and ecological processes and functions on which human flourishing depends at risk. This last decade has seen, on one hand, continued insistence on transformative action and on the other, uncertainty and instability with respect to traditional, established institutions, such as the state.

  4. 17. Phosphorus speciation in Swedish arable soils with high leaching potential

    Author : Frank Schmieder; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Eutrophication is threatening biodiversity and ecosystem functions in inland water bodies and estuaries world-wide. Phosphorus (P) export from arable land by e.g. leaching is a major contributor to eutrophication, with high P leaching losses from long-term manured mineral soils and cultivated organic soils (Histosols).

  5. 18. Deltas Apart - Factor Endowments, Colonial Extraction and Pathways of Agricultural Development in Vietnam

    Author : Montserrat Lopez Jerez; Ekonomisk-historiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Equality of Opportunity; Factor Endowments; Extraction; Agricultural Transformation; Initial Conditions; Rice Economy; Colonialism; Vietnam; Tonkin; Cochinchina;

    Abstract : This study provides an explanation of the different pathways of agricultural change and economic development in north and south Vietnam. It shows that pre-colonial factor endowments conditioned the development of the rice economies of the two deltas in Tonkin and Cochinchina. READ MORE

  6. 19. Ash transformation in thermochemical conversion of different biomass resources with special focus on phosphorus

    Author : Ali Hedayati; Marcus Öhman; Christoffer Boman; Kentaro Umeki; Anita Pettersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; agricultural biomass; forest residues; sewage sludge; ash transformation; release; potassium; phosphorus; combustion; gasification; bio charcoal; phosphorus recovery; Energy Engineering; Energiteknik;

    Abstract : A great potential exists for increasing the use of bioenergy in thermochemical processes by utilizing agricultural biomass, forest residues, and sewage sludge that have high availability. Many of these biomass assortments have high ash contents with relatively high concentrations of ash-forming elements such as potassium (K), calcium (Ca), silicon (Si), and phosphorus (P). READ MORE

  7. 20. Studies of ash transformation processes in thermochemical co-conversion of phosphorus-rich manure and sludge with biomass residues

    Author : Gustav Häggström; Marcus Öhman; Anders Lagerkvist; Nils Skoglund; Flemming Jappe Frandsen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sewage sludge; agricultural residues; forest residues; ash transformation; potassium; phosphorus; combustion; gasification; phosphorus recovery; Energy Engineering; Energiteknik;

    Abstract : Efficient use of resources and sustainable recovery of various materials are important to minimize the anthropogenic impact on the climate and environment. One such resource is the phosphorus (P) present in manure and sewage sludge. READ MORE
