  2. 16. Diurnal variation of stratospheric short-lived species

    Author : Maryam Khosravi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; chlorine monoxide; short-lived species; Arctic ClO; diurnal variation; tropical middle stratosphere; Arctic stratosphere;

    Abstract : Diurnal variation of stratospheric short-lived speciesMaryam KhosraviChalmers University of TechnologyDepartment of Earth and Space SciencesAbstractThe depletion of ozone in the stratosphere has a direct impact on the amount of ultravioletradiation reaching the Earth’s surface. The ozone abundance and distributionis controlled by the photo-chemical reactions and catalytic cycles involving halogens(chlorine and bromine), odd hydrogen and odd nitrogen species as well as by atmospherictransport.

  4. 17. Sustainable nutrition: Opportunities, risks and uncertainties from environmental and health perspectives

    Author : Elinor Hallström; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; disease; health; nutrition; land use; climate impact; Diet;

    Abstract : Food production and consumption are key drivers of environmental pressures and are essential factors in the promotion and maintenance of health. Production of food occupies more than one third of global land areas and is estimated to be responsible for some 30% of global greenhouse gas emissions. READ MORE

  5. 18. Hydrological Modeling for Climate Change Impact Assessment : Transferring Large-Scale Information from Global Climate Models to the Catchment Scale

    Author : Claudia Teutschbein; Jan Seibert; Chris Kilsby; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bias Correction; Climate Change; Climate Models; Ensembles; GCM; HBV; Hydrological Modeling; Precipitation; RCM; Split Sample Test; Streamflow; Sweden; Temperature; Uncertainty; Physical Geography; naturgeografi;

    Abstract : A changing climate can severely perturb regional hydrology and thereby affect human societies and life in general. To assess and simulate such potential hydrological climate change impacts, hydrological models require reliable meteorological variables for current and future climate conditions. READ MORE

  6. 19. Sustainable Arsenic Mitigation A Strategy for Scaling-up Safe Water Access : A Strategy for Scaling-up Safe Water Access

    Author : Mohammed Hossain; Prosun Bhattacharya; Marinus Eric Donselaar; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bangladesh; drinking water; arsenic mitigation; local tubewell driller; sediment color tool; low-manganese; Intermediate Deep aquifer; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : In rural Bangladesh, the drinking water supply is mostly dependent upon manually operated hand pumped tubewells, installed by the local community. The presence of natural arsenic (As) in groundwater and its wide scale occurrence has drastically reduced the safe water access across the country and put tens of millions of people under health risk.

  7. 20. Life Cycle Considerations in Sustainable Business Development. Eco-efficiency studies in Swedish industries

    Author : Reine Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; effectiveness; LCA; cleaner technology; environmental management; life cycle assessment; eco-efficiency; product ecology; sustainability; recycling; industrial ecology;

    Abstract : This thesis shows that there are reasons for placing some trust in the possibilities of aligning business goals and environmental goals, as well as in the possibilities of increasing eco-efficiency through technological development. The possibilities, although not unlimited, are not utilised to their full potential. READ MORE
