First achievements 2 Schlei Fjord © OpenStreetMap-contributors www.openstreetmap.org/copyright 3 Water catchment area „Schlei“ • Schlei > 42 km length; catchment area approx. 70.000 ha • 1 Federal Waterways and Shipping Office • Adminstrative levels: 2 districts and over 60 rural municipalities • 20 water and ground associations (maintaining water bodies) • 3 regional farmer associations 4 The unique history of the „Schlei“ UNESCO World Heritage : Haithabu & Danewerk Historic trading route : Baltic & North Sea Territorial changes: Danish-Prussian War in 1864 Different (agrarian) history: North ( Angeln ) & South ( Schwansen ) 5 EU Water Framework Directive Thematic map to the 2nd WFD management plan Ecological status for lakes & coastal waters very good good moderate unsatisfactory bad not classified Other EU-Regulations: Natura 2000 network (Habitats and Birds Directives) Marine Strategy Framework Directive + HELCOM Local working groups (mainly in honorary office): WG - Water Framework Directive • Natura 2000 advisory board 6 Agriculture – the key issue • Different agricultural structures in the North (Angeln) and South (Schwansen) of the Schlei fjord • Catchment area: 79 % agricultural land mainly high productive arable land • Main crop ranking: 1. Winter wheat 2. Silage maize 3. Winter oilseed rape 4. Winter barley * Catchment Area ** Entire characteristic landscape area in Schleswig-Holstein Data: agricultural structure survey 2016 (Statistical office North Germany) 7 Biogas production Landscape changes: increase of biogas plants 1990 - 2013 Increase of biogas plants per km² 0 – 0,1 0,1 – 0,5 0,5 – 1,8 Increase of installed electric power (kW/km²) 0 – 48 kW 48 – 88 kW 88 – 784 no changes without biogas plants MELUND Landschaftsrahmenplan 2019 In the north-eastern part of Schleswig-Holstein > 200 biogas plants with more than 180.000 kW installed electrical power Bundesnetzagentur 2014 8 Farm-gate nutrient balances Phosphorus Nitrogen Henning & Taube 2020 9 Pathways of phosphorus Pathways of phosphorus of the river basin districts in Schleswig Holstein Run off Erosion Interflow Ground water Drainages Deposition Sewage separation Small wastewater treatment plants Industry Large wastewater treatment plants Tetzlaff et al. 2016 Risk due to water erosion : medium to very high landscape: glacial carved, slightly hilly Nutrient availability in the upper soil: predominantly high to very high 10 Nutrient inputs Schlei fjord low freshwater inflow few water exchange with the open sea River system „Füsinger Au“ drains over 55 % of the catchment area 11 Nutrient inputs Schlei fjord low freshwater inflow few water exchange with the open sea River system Füsinger Au drains over 55 % of the catchment area 12 Initiation Modell Projekt Schlei Foto: Klaus-Günter Nebel, 2018 Foto: Thomas Eisenkrätzer 13 Outline 1.
