  1. 1. Miljörörelsens mångfald

    Författare :Magnus Boström; Rolf Lidskog; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Environmental organisation; Environmental movement; Social movement; Ecological modernization; Environmental politics; Environmental knowledge; Framing processes; Resource mobilization; Political opportunity structure; Collective identity; Niche.; Sociology; sociologi; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : In the thesis, the conditions, possibilities, and limitations for Swedish environmental organisations to influence other actors — state agencies, political organisations, enterprises and the Swedish public — are analysed. The focus is on their practice in the nineties, implying a context in which different actors, to a greater extent, have accepted the significance of environmental issues, demand knowledge of and solutions to environmental problems, and with new conflicts continously arising.

  2. 2. Road Ecology for Environmental Assessment

    Sammanfattning : Transport infrastructure is closely linked to several politically relevant sustainability issues, and since 1985 a formalized environmental assessment process is linked to planning and construction of new roads and railways in the EU (EU directives 85/337/EEC and 2001/42). The aim of the environmental assessment process is to think in advance; to identify, predict and evaluate significant environmental changes resulting from a proposed activity, in order to adjust the proposed activity accordingly and to avoid unnecessary and unexpected consequences.

    Sammanfattning : In recent decades, Rwanda has been affected by the loss and fragmentation of natural habitats for native species of animals and plants. As a consequence, landscape connectivity—i.e. LÄS MER

  4. 4. Car movement patterns and the PHEV

    Författare :Lars Henrik Björnsson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; PHEV; Sweden; PHEV viability; PHEV potential; car movement pattern; GPS logging; BEV; electrification; brake energy regeneration; battery size;

    Sammanfattning : Roughly 30% of Sweden’s total greenhouse gas emissions originate from transport and a majority of them from cars. The plug-in hybrid electric vehicle (PHEV) avoids the range limitation of the fully electric vehicle while still allowing for a major share of the fuel to be replaced by electricity from the grid and can thereby reduce greenhouse gas emissions, local pollutants and energy security concerns.

  5. 5. Incorporation and preservation of geochemical fingerprints in peat archives

    Författare :Sophia V. Hansson; Richard Bindler; Dominik Weiss; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Peat; Beryllium; bulk density; C N-ratio; decomposition; deposition; downwash; elemental mobility; geochemistry; humification; lead; light transmission; mercury; peat accumulation; precipitation; Environmental Science; miljövetenskap;

    Sammanfattning : The present status of the environment, including environmental problems such as heavy metal accumulation in aquatic and terrestrial ecosystems, is in part the consequence of long-term changes. Cores from peatlands and other natural archives provide us with the potential to study aspects of the atmospheric cycling of elements, such as metal pollutants, on timescales much longer than the decade or two available to us with atmospheric deposition monitoring programs.
