CLEARANCE-CircuLar Economy Approach to River pollution by Agricultural Nutrients with use of Carbon-storing Ecosystems

Riverine wetlands provide a range of ecosystem services: cultural (esthetics, recreation and education), provisioning (storage and retention of water), supporting (soil formation and nutrient cycling), regulating (regulation of erosion, natural hazards, hydrological flows, climate, water purification and waste treatment). The project CLEARANCE focuses on the role of wetland buffer zones (WBZ) in agricultural catchments that clean water from excess nutrients before it reaches the river, as well as substantially contribute to the natural purification of river water. The project aims to demonstrate this role of WBZs using model catchments, while at the same time examining synergies between water purification and other ecosystem services. The key concept of CLEARANCE is to enhance multifunctional use of riverine wetlands via circular economy, where nutrients captured in wetland biomass are re-used to produce energy (via combustion, biogas or pyrolysis), materials or soil substrates (compost), while at the same time reducing greenhouse gas emissions via rewetting of drained organic soils and re-establishment of peat formation. Last but not least, riparian biodiversity and recreational functions of riverine wetlands are treated as co-benefits of the above-listed services, altogether allowing for a multi-faceted evaluation of WBZs and developing an integrated framework - socio-economic, environmental and political - for the implementation of WBZs in circular economy. CLEARANCE will deliver: (1) assessment of synergies and constraints between nutrient removal in WBZ and biomass utilization; (2) analysis of market and non-market values of rivers and river ecosystem services (as co-benefits of WBZ); (3) quantification and upscaling of costs and benefits of WBZ at the catchment scale; (4) policy and social network analysis concerning feasibility of using WBZ in circular economies as a solution to agricultural nutrients pollution; (5) market assessment of commodification options of WBZ-related ecosystem services, including nutrient removal and biomass production.
