  2. 21. Actors at the interface between socio-technical and ecological systems: Analytical starting point for identifying mitigation possibilities in the case of on-site sewage systems

    Author : Are Wallin; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; interface-actors; Eutrophication; problem-structuring approach; wastewater treatment systems; homeowners;

    Abstract : The thesis addresses several issues related to factors influencing actors around environmental problems to decrease the environmental pressures. Systems treating sewage at the scale of one to a few households (on-site sewage systems, OSSs) comprise a Swedish case study. READ MORE

  4. 22. Sulfur Capture and Oxidation of Calcium Sulfide in PFBC

    Author : Kuanrong Qiu; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxidation; model; pressure; sulfur; PFBC; CaS; limestone; CaSO4; PTGA; regeneration;

    Abstract : Sorbents such as limestone are successfully used for removal of SO2 during pressurized fluidized bed combustion (PFBC) processes. However, there still remains a strong incentive to reduce the consumption of such sorbents. READ MORE

  5. 23. A Pressure-oriented Approach to Water Management

    Author : Xingqiang Song; Björn Frostell; Ronald Wennersten; Maarten Siebel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DPR model. DPSIR framework. human-environment. industrial ecology. life cycle thinking. pressure-oriented approach. socioeconomic metabolism. systems thinking. water information. water quality. water quantity;

    Abstract : Without a comprehensive understanding of anthropogenic pressures on the water environment, it is difficult to develop effective and efficient strategies to support water management in a proactive way. A broader systems perspective and expanded information systems are therefore essential to aid in systematically exploring interlinks between socioeconomic activities and impaired waters at an appropriate scale.

  6. 24. From Corals to Corporations : Social-ecological dynamics in the Anthropocene ocean

    Author : Jean-Baptiste Jouffray; Magnus Nyström; Toby Gardner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anthropocene; Ocean; Coral reef; Finance; Regime shift; Sustainability; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : The ocean has always been of paramount importance for the development of human civilisation. Today more than ever, the prospect of a new era of ‘blue growth’ poses great sustainability and governance challenges as marine ecosystems worldwide face unprecedented cumulative pressures from local human impacts, global climate change and distal socioeconomic processes.

  7. 25. Assessing future effects on lake ecosystem resilience using data analysis and dynamic modelling : Modelling the effects of extreme weather events and climate warming on lakes

    Author : Jorrit P. Mesman; Bastiaan W Ibelings; Stéphane Goyette; Don C Pierson; Karsten Rinke; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extreme events; Storms; Modelling; Climate change; Thermal structure; Phytoplankton;

    Abstract : Extreme weather events can have short-term and long-term effects on lake thermal structure, nutrient dynamics, and community composition. Moreover, changes in lake variables induced by global climate change may influence the response and recovery of lake ecosystems to extreme weather events. READ MORE
