  1. 36. Modelling the Impact of Climate and Socio-Economic Changes on Nutrient Dynamics in the Catchment of Lake Vomb

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Yanhe Zhou; [2023]
    Keywords : Climate change; hydrological modelling; nutrient; RCP; socioeconomic development; SSP; SWAT; water quality modelling;

    Abstract : Climate change and socio-economic development are greatly affecting the quality of freshwater, especially the excessive accumulation of nutrients (N and P), which eventually leads to the occurrence of eutrophication. Lake Vomb is one of the main sources of drinking water in southern Sweden and the nutrient load from the catchment makes it a eutrophic lake with recurring algal blooms. READ MORE

  4. 38. System ecology of legumes mixes in ley production : impact on pollinating insects and further implications for production in northern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Philippe Simon; [2023]
    Keywords : Ley production; Nitrogen fixation; Pollination ecology;

    Abstract : The population and diversity of pollinating insects in Europe are declining, partly due to lossof habitat. In agricultural landscapes, farming practices with more intensified land use haveincreased. In Swedish agricultural habitats, most ley production is dominated by grass and red clover (Trifolium pratense). READ MORE
