  1. 26. Assessment of freshwater ecosystem services : with a case study in river Arbogaån

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Emelie Möllersten; [2018]
    Nyckelord :ecosystem services; freshwater; climate change; flooding; assessment;

    Sammanfattning : Humans are dependent on a large variety of services that come from the eco-systems around us. Some of these ecosystem services are provided by rivers and lakes and include for example drinking water, water for irrigation and industry, flood control, climate regulation, and recreation.

  3. 27. Development of Tempeh on Swedish Legumes

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Nils Åström; [2018]
    Nyckelord :Product development; Process optimization; Food technology; Fermentation; Tempeh; Meat substitute; Vegan product; Swedish legumes; Livsmedelsteknologi; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : The emerging market for meat substitutes has largely been filled with different types of soy products. Although soy usually has a lower environmental impact than meat, soy is not entirely unproblematic. Deforestation and global transportations are two negative effects of the increasing production of soybeans. LÄS MER

  4. 28. The influence of soil management on soil health : an on-farm study

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Hanna Williams; [2018]
    Nyckelord :crop diversity; soil health assessment; indicator; soil quality; ecosystem services;

    Sammanfattning : The capacity of a soil to provide ecosystem services without negative impacts on the environment is defined as soil health. Healthy soils are a fundamental resource for agricultural production and our ability to feed a growing global population. We must therefore increase our understanding of how soil health is affected by soil management. LÄS MER

  5. 29. Hassel i gotländska ängen. Samband mellan historiskt hasselbruk och biologisk mångfald

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Elina Ambjörnsson; Max Lindgren; [2017-06-13]
    Nyckelord :hazel; biodiversity; intangible cultural heritage; environmental management; long-horned beetles; hassel; biologisk mångfald; immateriellt kulturarv; naturvård; långhorniga skalbaggar;

    Sammanfattning : This essay explores the traditional usage of hazel in wooded meadows in the island of Gotland, and the relations between this usage and the biodiversity of these lands. Research on relations between historical land-use and biodiversity is a relatively new field and there is presently no such undertaken research on traditional usage of hazel. LÄS MER

  7. 30. Multiple Substrate-Induced Respiration and Isothermal Calorimetry : Applicability in Risk Assessment of Contaminated Soil

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Caroline Wright; [2017]
    Nyckelord :Risk assessment; biological indicators; multiple substrate-induced respiration; MSIR; MicroRespTM; isothermal calorimetry; calorespirometric ratio; contamination; Cu; PAH; Riskbedömning; biologiska indikatorer; multipla substrat-inducerad respiration; MSIR; MicroRespTM; isotermisk kalorimetri; calorespirometric ratio; förorening; Cu; PAH;

    Sammanfattning : At present, soils face great threats. Consequences of human activities, such as climate change, acidification and contamination result in decreased soil health. This is a threat to human health and well-being, since our society is dependent on soil ecosystem services. LÄS MER
