  2. 16. Implications of land use on the carbon cycle - Impacts of long-term human activities on terrestrial organic matter input to aquatic ecosystems in southern Sweden

    Author : Bingjie Yang; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lignin phenols; pollen; Land Reconstruction Algorithm; terrestrial organic matter; southern Sweden; sediments;

    Abstract : Human activities have a huge impact on the carbon cycle by modifying the landscape. Vegetation cover changes attributed to forest clearance and the expansion of agricultural land increases soil erosion, organic matter and other nutrient delivery from terrestrial to aquatic ecosystems.

  4. 17. Modelling trade-offs between forest bioenergy and biodiversity

    Author : Xi Pang; Ulla Mörtberg; Karin Öhman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : Globally, biodiversity is declining due to loss, fragmentation and degradation of habitat, which undermines ecosystem functioning and therefore threatens also the ability of ecosystems to supply ecosystem services. Moreover, there is a need for adapting to climate change as well as securing the supply of energy, which have led to a shift in energy consumption from fossil fuel to renewables, especially biomass, which in turn put increasing pressure on ecosystems and biodiversity.

  5. 18. Data preparation, hydrodynamic and contaminant transport shallow-water simulations of Lake Victoria

    Author : Seema Paul; Vladimir Cvetkovic; Jesper Oppelstrup; Roger Thunvik; Felix Mtalo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lake bathymetry model; Steady-state analysis; Numerical model validation; Lake water balance; Correlation and seasonal variations; Solute transport; Vattendjupskarta; Validering av numerisk modell; Vattenbalans; Korrelationer och säsongs-variation; Transport av lösliga ämnen; Mark- och vattenteknik; Land and Water Resources Engineering;

    Abstract : This study explores shallow lake numerical hydrodynamic processes that support model development and validation, extreme events and effects of water circulation in Lake Victoria. Lake Victoria is the second largest freshwater lake in the world, and the largest in East Africa. READ MORE

  6. 19. Private Rivers : Politics of Renewable Energy and the Rise of Water Struggles in Turkey

    Author : Mine Islar; LUCSUS; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Renewable energy; neoliberal state; water rights; privatisation; Turkey; sustainability;

    Abstract : Private Rivers is a study of contested processes whereby use rights to water are privatised for electricity production. It engages with the issues of renewable energy solutions and the sustainability of run-of-river hydro projects in Turkey by investigating the connection between these policies and justice for rural populations, whose livelihood depends on the rivers.

  7. 20. The Collective Action Dilemma in Managing Transboundary Freshwaters : An Analysis of an Outcome-Driven Framework

    Author : Jakob Granit; Carl Christiansson; Helle Skånes; Aaron Wolf; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Benefit generation; common-pool resources; governance; management; outcomes; regional public goods; transboundary waters; value chain; geografi med naturgeografisk inriktning; Geography; Physical Geography;

    Abstract : It is recognised by society that freshwater resources play a major role in economic development and in maintaining life supporting ecosystems services. Transboundary river basins cover about 45% of the earth’s land surface and their governance is therefore of critical importance. READ MORE
