Recommendations for further action
The BONUS RETURN project explored ecotechnologies to reduce, recycle and reuse the biomaterials of wastewater and agriculture in the Fyrisån (Sweden), Vantaanjoki (Finland) and Slupia (Poland) river basins. The Vantaanjoki case study shows that gypsum offers one way to address Baltic Sea eutrophication problems. This brief highlights the potential for upscaling gypsum use in the Baltic Sea Region as a promising component of Baltic Sea protection actions.
Project SAVE, the River Vantaanjoki project and NutriTrade, a project of the EU’s Interreg Central Baltic Programme, offer the following policy recommendations for further action to assess and encourage implementation of gypsum soil amendment across the Baltic region:
- Development of a national plan to implement the use of gypsum in the coastal areas of Southern Finland, and to include gypsum in the national Finnish agricultural support scheme.
- Provision of government agricultural subsidies to cover the costs farmers face in using gypsum soil amendment.
- Amendment of the EU Common Agricultural Policy (CAP) and HELCOM recommendations to promote gypsum application in the Baltic Sea catchments. The currently scheduled CAP reform for 2021 is a particularly important opportunity.
- Additional research on the economic, environmental and societal benefits of gypsum in countries outside of Finland.
