  2. 1. Chlorine Cycling in Terrestrial Environments

    Author : Malin Montelius; David Bastviken; Teresia Svensson; Katarina Abrahamsson; Linköpings universitet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES; Chloride; organic chlorine; chlorination; dechlorination; 36Cl; risk assessment modelling; Klorid; organiskt klor; klorering; deklorering; klor-36; riskmodellering;

    Abstract : Chlorinated organic compounds (Clorg) are produced naturally in soil. Formation and degradation of Clorg affect the chlorine (Cl) cycling in terrestrial environments and chlorine can be retained or released from soil. READ MORE

    Abstract : This thesis studied the viability of recycling filter substrates as soil amendments after being used in on-site systems for phosphorus (P) removal from wastewater. Focus was put on the materials Filtra P and Polonite, which are commercial products used in compact filters in Sweden. READ MORE

  5. 3. Insect pollination of oilseed rape

    Author : Sandra Lindström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Ecological intensification of agriculture is suggested as a way to reach higher crop yields without increasing inputs that may degrade the environment. Increased insect pollination in crops, such as oilseed rape, Brassica napus, has been suggested to increase yields, but is rarely integrated in crop management. READ MORE

  6. 4. The complexity of seafood trade relations across scales

    Author : Laura G. Elsler; Maja Schlüter; Simon A. Levin; Anne-Sophie Crépin; Jennifer Jacquet; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; SOCIAL SCIENCES; vetenskap om hållbar utveckling; Sustainability Science;

    Abstract : There is growing concern about the unprecedented rise in international seafood trade that relies on increasingly overused and climate-driven fisheries. Seafood trade relations, the multi-dimensional relations between fishers, traders, and countries for seafood exchange and other interactions, are central in the process of globalization. READ MORE

  7. 5. Social-ecological performance of collaborative wildlife governance : the case of Swedish moose management

    Author : Sabrina Dressel; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; LANTBRUKSVETENSKAPER; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; AGRICULTURAL SCIENCES; SOCIAL SCIENCES;

    Abstract : Natural resources such as wildlife are part of social-ecological systems, which are characterized by inherent complexity, uncertainty, and changes. Therefore, collaborative, decentralized, and adaptive approaches tend to be preferred in environmental governance. READ MORE
