  2. 1. Urban environmental stewardship : Roles and reasons for civic engagements in governance of social-ecological systems

    Author : Johan Enqvist; Maria Tengö; Örjan Bodin; Bengt Karlsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental governance; urbanization; social-ecological systems; Bangalore; India; collective action; naturresurshushållning; Natural Resources Management;

    Abstract : Stewardship as a concept is increasingly brought forward as a goal to reach sustainability goals of ensuring human wellbeing within the limits of Earth’s life support systems. Scholarship on the required capacities for planetary stewardship is growing rapidly, as are the insights. READ MORE

  4. 2. Phosphorus recovery for fertilisers from dairy wastewater – Sustainability assessment at early stages of technology development

    Author : Marta Behjat; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental impacts; LCA; screening; phosphorus recovery; sustainability; indicator; meta-analysis; wastewater treatment; dairy wastewater;

    Abstract : A reduction in the availability of phosphate rock resources for fertiliser production coincides with an increase in phosphorus-rich dairy wastewater in Europe. This confluence of events has led to the development of technologies for phosphorus recovery from dairy wastewater and the use of the products as fertilisers in agriculture. READ MORE

  5. 3. Method Development for Environmental Risk Assessment of Shipwrecks

    Author : Hanna Landquist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; environmental risk assessment; decision support; fault tree analysis; shipwreck;

    Abstract : Potentially polluting shipwrecks containing oil or other hazardous substances may posea threat to the marine environment. This is a global problem and many shipwrecks stemfrom the Second World War and have been deteriorating on the sea floor since then. READ MORE

  6. 4. 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

  7. 5. Modelling impact climate-related change on the thermal responses of lakes

    Author : Ana I. Ayala; Donald C. Pierson; Stéphane Goyette; Andreas Lorke; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Modelling; climate change; lakes; thermal structure; surface heat fluxes; extreme events;

    Abstract : In response to climate-related changes, lakes worldwide have experienced warmer surface water temperatures, shorter ice cover periods and changes in lake stratification. As these aspects of lake dynamics exert substantial control over nutrient availability, oxygenation and biogeochemical cycling, predicting changes in lake water temperature and stratification dynamics can improve our understanding of the consequences of warming on lake ecosystems.
