  1. 1. Drivers of carbon sink function in tropical seagrass beds : influence of carbon import, plant composition, seascape configuration and human activities

    Författare :Rashid O. Ismail; Mats Björk; Martin Gullström; Maria E. Asplund; Amelia S. Buriyo; Matern S.P. Mtolera; Teresa Alcoverro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon sequestration; tropical seagrass meadows; coastal seascape; landscape configuration and transformation; calcification; allochthonous carbon; community respiration; carbon sink; human disturbance; coastal conservation; Plant Physiology; växtfysiologi;

    Sammanfattning : Seagrass meadows are effective carbon sinks, sequestering atmospheric CO2 and capturing allochthonous organic material, storing organic carbon (Corg) in their sediments, so called Blue Carbon. In tropical areas, seagrass meadows have a high number of calcareous organisms, which can offset carbon sequestration by releasing CO2 through their calcification. LÄS MER

  3. 2. Bacterioplankton in the light of seasonality and environmental drivers

    Författare :Carina Bunse; Jarone Pinhassi; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; marine bacteria; marine microbiology; seasonal succession; ocean acidification; proteorhodopsin; photoheterotrophy; microbial time series; Akvatisk ekologi; Aquatic Ecology; Mikrobiologi; Microbiology; Miljövetenskap; Environmental Science;

    Sammanfattning : Bacterioplankton are keystone organisms in marine ecosystems. They are important for element cycles, by transforming dissolved organic carbon and other nutrients. Bacterioplankton community composition and productivity rates change in surface waters over spatial and temporal scales. LÄS MER

  4. 3. Stimulating the diffusion of environmental technologies through export

    Författare :Wisdom Kanda; Olof Hjelm; Dzamila Bienkowska; Totti Könnölä; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; Environmental Technology; Technology Diffusion; Export; Internationalisation;

    Sammanfattning : Contemporary environmental problems represent complex societal challenges, and as these problems become increasingly global, the international diffusion of environmental technologies is essential. One way to diffuse technologies internationally is through export. LÄS MER

  5. 4. Felling Forests from Afar: Quantifying Deforestation Driven by Agricultural Expansion and International Trade

    Författare :Florence Pendrill; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Forest transitions; Land cover; Carbon footprints; Agriculture; Forestry; Carbon emissions; Land use; International trade; Deforestation;

    Sammanfattning : Deforestation is a major source of human-caused greenhouse gas emissions and the largest threat to terrestrial biodiversity. Most forest loss is due to the expansion of agricultural land use increasingly driven by international demand for food, fuel and fibre. LÄS MER

  7. 5. Model for change in production systems triggered by environmental requirements : considerations, drivers, key factors

    Författare :Anna Sannö; Mats Deleryd; Mats Winroth; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; change management; environment; sustainable development; Innovation and Design; innovation och design;

    Sammanfattning : Industry is a key player in the transition to a sustainable society where manufacturing companies need to respond to the challenges of environmental concerns in several ways. Still, even if several efforts have been made in practise and academia, more research within operations management is addressed in relation to implementing sustainable solutions. LÄS MER
