Mitigation measures for phosphorus and nitrogen under changing climate: conflicts and synergies


Nutrient concentrations, loads and stoichiometry (i.e., N:P ratio) in agricultural runoff affect the quality of surface waters. In Norway, the reduction of nutrient runoff is challenged by the sloped landscape, variable weather and changing climate with an increasing number of extreme hydrological events.
Mitigation measures for reducing nutrient losses are pressingly needed but they do not always work simultaneously or equally for both N and P, due to the differences in their agronomic and biogeochemical characteristics and dominant transport pathways. In support of decision-makers and farmers’ selection of effective mitigation measures, this project aims to increase the knowledge base on how nutrient, soil, crop, water and landscape management options affect P and N losses in runoff as well as N:P stoichiometry similarly or differently under variable weather conditions and changing climates, and to identify effective mitigation measures with climate-adaptation potential. The project will be conducted through an inventory, analysis and synthesis of available data in Norway to demonstrate how/where/when different management options have worked in reducing N and P concentrations and loads and changing N:P ratios, and potential conflicts and synergies in N and P reductions. The project will provide suggestions on mitigation measures that can be used by farmers for simultaneously reducing both N and P.

PATH4MED: Demonstrating innovative pathways addressing water and soil pollution in the Mediterranean Agro-Hydro-System.


Path4Med is a multi-participatory and multidisciplinary project that will pave clear pathways towards zero water and soil pollution in the agro-hydro-system of the Mediterranean sea basin and other European seas through an innovative triple bottom line approach achieving economic, social, and environmental sustainability to ensure human well-being and ecosystems functioning.
