  2. 21. Novel approaches in modeling of soil carbon : Upscaling theories and energetics

    Author : Arjun Chakrawal; Stefano Manzoni; Hyun-Seob Song; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Microorganisms; soil C cycling; spatial heterogeneity; energetics; thermodynamics; microbial metabolism; calorespirometric ratio; microbial traits; heat dissipation; microscale; Physical Geography; naturgeografi;

    Abstract : Soils contain more carbon (C) than terrestrial (above ground) and atmospheric carbon combined. Mismanagement of soil C could lead to increased greenhouse gas emissions, whereas practices leading to increased C storage would help mitigate climate change while improving soil fertility and ecological functions.

  4. 22. Unravelling Sustainability : The complex dynamics of emergent environmental governance and management systems at multiple scales

    Author : Lucas Dawson; Ingrid Stjernquist; Marine Elbakidze; Raimonds Ernsteins; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Integrated adaptive environmental governance and management; Social-ecological system dynamics; Complex systems; Sustainability transitions; Sustainability strategies; Multi-level governance; Causal loop diagrams; Green Infrastructure; Landscape restoration; Habitat restoration; Biodiversity conservation; Comprehensive planning; Stakeholder participation; System thinking; Water Framework Directive; Sustainable water governance; Collaborative learning; Communities of practice; Knowledge management; Physical Geography; naturgeografi;

    Abstract : This thesis adopts a complex systems approach to investigate the dynamic emergence of sustainable environmental governance and management systems in multiple contexts in Europe. Accelerating rates of environmental degradation across the world have called the legitimacy of previous environmental governance and management arrangements into question. READ MORE

  5. 23. Waterborne pollution from mining in cold climates : Potential catchment-scale immobilization of substances by microbial sulfate reduction (MSR)

    Author : Sandra Fischer; Jerker Jarsjö; Gunhild Rosqvist; Carl-Magnus Mörth; Anna-Kaisa Ronkanen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; abandoned mines; metal pollution; sulfur isotopes; bacterial sulfate reduction BSR ; nature-based solution NBS ; naturgeografi; Physical Geography;

    Abstract : Waterborne pollution from mining is impacting groundwater and surface water resources in many regions of the world. Main problems include acidification and high levels of dissolved toxic metals that adversely affect humans and ecosystems. READ MORE

  6. 24. Comparison of dating methods for paleoglacial reconstruction in Central Asia

    Author : Natacha Gribenski; Krister N. Jansson; Arjen P. Stroeven; Frank Preusser; Jonathan M. Harbor; Marc Bateman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciation; Optically stimulated luminescence dating; Cosmogenic nuclide exposure dating; EMCCD camera; Physical Geography; naturgeografi;

    Abstract : Reconstruction of former Central Asian glaciers extents can provide valuable information about past atmospheric circulation variations. These extents, often marked by terminal moraines, need to be chronologically constrained. Cosmogenic nuclide exposure (CNE) dating is widely used to directly date moraines. READ MORE

  7. 25. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities

    Author : Daniela Guasconi; Gustaf Hugelius; Sara Cousins; Stefano Manzoni; Petra Fransson; David Johnson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soil; soil carbon; soil ecology; roots; root traits; microbial communities; grasslands; climate change; drought; land management; compost; naturgeografi; Physical Geography;

    Abstract : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. READ MORE
