  1. 1. Increased body growth rates of northern pike (Esox lucius) in the Baltic Sea : importance of size-selective mortality and warming waters

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Terese Berggren; [2019]
    Nyckelord :Northern pike; Esox lucius; Back-calculated length; Body growth; Size-selective mortality; Warming waters; Baltic Sea;

    Sammanfattning : The northern pike, Esox lucius Linnaeus (1758), is a highly valuable species in recreational fishing, and plays a vital role as a keystone predator in the structuring of fish communities in temperate lakes and brackish waters. Ma-jor declines of pike in the Baltic Sea have been recorded, particular of larger pikes, which may have cascading effects on abundances of lower ecosys-tem compartments. LÄS MER

  2. 2. Biologisk påverkan på den marina kolcykeln

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Charlotta Ruuskanen; [2018]
    Nyckelord :Earth and Environmental Sciences;

    Sammanfattning : The rising amount of carbon dioxide in the atmosphere is an environmental problem. The temperature of the Earth is rising as a result of the large quantities of greenhouse gas emissions. LÄS MER

  3. 3. A GIS analysis of electricity production using pressure retarded osmosis in the Nordic countries

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :David Jirout; [2015]
    Nyckelord :osmotic power; pressure retarded osmosis; sustainable development; carbon neutral renewable energy; GIS; NORDEL;

    Sammanfattning : Osmotic power is an unexploited source of renewable energy that is based on mixing two types of water with a different salinity gradient. Osmotic power production (if life-cycle analysis of all necessary components is ignored) does not emit greenhouse gases to the atmosphere as opposed to fossil fuels employed in electricity production today, thus osmotic power does not systemically contribute to global warming and climate change.

  4. 4. Local solutions for water management at Muhanga Resource Center, Uganda

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Juanhan Guo; [2015]
    Nyckelord :Uganda; Muhanga; Stormwater; ArcGIS; PRA; Flooding; Drought; Water Harvesting; Sanitation; Solutions; Technology and Engineering;

    Sammanfattning : Uganda has experienced extreme weather for example droughts and flooding for many years resulting from rainfall deficits and variability. With the increased manifestation of negative effects related to climate change and global warming, this challenge is becoming greater and greater. LÄS MER

  5. 5. Integrating Sustainability in the Food Supply Chain : Two Measures to Reduce the Food Wastage in a Swedish Retail Store

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Herman Nilsson; [2013]
    Nyckelord :Food loss; Food Supply Chain; Climate Impact; Resource Depletion; Sustainable Development.;

    Sammanfattning : Due to the growing world population, the environmental impact from the food supply chain is currently increasing in a global perspective, essentially because the global food consumption is increasing in general. The UN Food and Agriculture Organization (FAO) estimates that about one third of the edible portions of the food produced globally is lost or wasted along the way from raw materials to the dinner plate.
