The Bulgarian Wetlands Restoration and Pollution Reduction Project, a pilot initiative under the GEF Black Sea/Danube Strategic Partnership, aims to control nutrient inflow to the Black Sea. The project focuses on wetlands restoration and nature protection, with Persina Nature Park and Kalimok/Brushlen Protected Site as key areas. It received funding from GEF, the World Bank, and other donors, totaling USD 13.28 million. By reconnecting wetlands to the Danube and promoting sustainable land use, the project aims to reduce trans-boundary nutrient loads and restore biodiversity.
