RECOCA will provide scientific outputs that facilitate the implementation of ecosystem-based environmental management of the Baltic Sea, since most management decisions combating eutrophication have to be carried out in the catchment area of the Baltic Sea. To manage remedial actions involving 85 million people in a dozen countries spanning over 105 major watersheds analysis and modelling tools are necessary, which can address the full scope and the various spatiotemporal scales of the problem. The overall aim of the proposed study is (i) to simulate possible future riverine nutrient loads to the Baltic Sea in realistic river basin management scenarios, (ii) to estimate cost functions for load reductions and improvements in ecological indicators, and (iii) to suggest cost allocation schemes for countries within the Baltic Sea catchment. We will apply a nested hierarchical approach to simulate nutrient loads to the Baltic Sea in combination with abatement costs for the various measures ranging from farm scale over regional meso-scale river basin representing EU water districts and characteristic river basin types to entire drainage basins to the Baltic Sea.
