Modelling the effects of bio-based fertilizers use on air and surface water pollution at sub-basin and European scales

Agricultural activities led to considerable nutrient losses to the environment causing pollution. Upcycling organic waste is one of the promising options to produce renewable bio-based fertilizers. However, the environmental impacts thereof are not completely known. My research aims to assess the effects of bio-based fertilizer use on water and air pollution at sub-basin and European scales, and to explore mitigation options. To this end, I will link an agricultural and a water quality model to quantify the nutrient emissions to air and waters. Then, I will assess the mitigation options to reduce environmental impacts of increased bio-based fertilizer use.
