The Bonus Programme- Science for a better future of the Baltic Sea Region The BONUS Programme is supported by the national research funding institutions in the eight EU member states around the Baltic Sea and the EU Research Framework Programme (Article 185). Scientists from the Russian Federation participate in BONUS research projects through special agreements. For info on BONUS see: http://www.bonusportal.org/ For info on EC Article 185 see: http://cordis.europa.eu/fp7/art185/about-185_en.html
Main objective of Soils2Sea: • To develop new innovative tools for reducingnutrientloadings to the Baltic Sea throughimprovedunderstanding of nutrientspathways, retention processes and differentiated and optimizedregulation

Keyoutcomes - 1 Soils2Sea will carry out a joint research effort at a macroregional level with the following key outcomes: • New methodologies for the planning of differentiated regulations based on new knowledge of nutrient transport and retention processes between soils/sewage outlets and the coast. • Evaluation of how differentiated regulation can offer more cost efficient solutions towards reducing the nutrient loads to the Baltic Sea. • Analysis of how changes in land use and climate may affect the nutrient load to the Baltic Sea as well as the optimal location of measures aiming at reducing the load.
Keyoutcomes - 2 4. A high-resolution model for the entire Baltic Sea Basin with improved process descriptions of nutrient retention in groundwater and surface water tailored to make detailed simulations of management regulationsdifferentiated in space. 5. New knowledge based governance and monitoring concepts that acknowledge the relevant aspects of EU directives and are tailored towards decentralised decision making and differentiated regulations. 6.Test of concepts and tools at a hierarchy of scales ranging from small scale (km2) through medium scale (103 km2) to the Baltic Sea catchment scale (106 km2).
