Katarzyna Izydorczyk is a professor at the European Regional Centre for Ecohydrology, Polish Academy of Sciences (ERCE PAS). Her research concentrates on systemic ecohydrological solutions in catchment-level management of water resources, with special emphasis on eutrophication of reservoirs and reduction of non-point source pollutions in agricultural catchments. She was the main researcher in the European project LIFE+EKOROB, awarded by the European Commission as “Best of Life+”. Prof. Izydroczyk currently participates in the international projects WATERDRIVE (Water driven rural development in the Baltic Sea Region of the Interreg Baltic Sea Region EU Programme) and RECONNECT (Regenerating ecosystems with nature-based solutions for hydro-meteorological risk reduction, Horizon 2020 EU Programme).
