In this paper, we outline several recent insights for the priorities and challenges future research reducing phosphorus (P) based water eutrophication in agricultural landscapes of Northwest Europe. We highlight that new efforts best be focused on headwater catchments as they are a key influence initial chemistry larger river catchments, here many management interventions most effectively made. emphasize lack understanding how climate change will impact P losses from landscapes.

Wetland Technology: Practical Information on the Design and Application of Treatment Wetlands

IWA Publishing eBooks, Journal Year: 2019, Volume and Issue: unknown

Published: Oct. 14, 2019

Water quality standards across the world are being re-written to promote healthier ecosystems, ensure safe potable water sources, increased biodiversity, and enhanced ecological functions. Treatment wetlands used for treating a variety of pollutant waters, including municipal wastewater, agricultural urban runoff, industrial effluents, combined sewer overflows, among others. particularly well-suited sustainable management because they can cope with variable influent loads, be constructed local materials, have low operations maintenance requirements compared other treatment technologies, provide additional ecosystem services. The technology has been successfully implemented in both developed developing countries.The first IWA Scientific Technical Report (STR) on Wetland Technology was published 2000. With exponential development since then, generation new STR facilitated by Task Group Mainstreaming Technology. This conceptualized written leading experts field. report presents latest applications within an innovative planning framework multi-purpose wetland design. It also includes practical design information collected from over twenty years experience practitioners academics, covering experiments at laboratory pilot-scale up full-scale applications.Scientific No. 27

Optimisation of urban-rural nature-based solutions for integrated catchment water management

Journal of Environmental Management, Journal Year: 2022, Volume and Issue: 329, P. 117045 - 117045

Published: Dec. 20, 2022

Nature-based solutions (NBS) have co-benefits for water availability, quality, and flood management. However, searching optimal integrated urban-rural NBS planning to maximise at a catchment scale is still limited by fragmented evaluation. This study develops an optimisation framework based on the CatchWat-SD model, which developed simulate multi-catchment cycle in Norfolk region, UK. Three rural (runoff attenuation features, regenerative farming, floodplain) two urban (urban green space, constructed wastewater wetlands) interventions are into model range of implementation scales. A many-objective problem with seven management objectives account flow, quality cost indicators formulated, NSGAII algorithm adopted search portfolios. Results show that more significant impacts across catchment, increase implementation. Integrated can improve simultaneously, though trade-offs exist between different objectives. Runoff features floodplains provide greatest benefits availability. Regenerative farming most effective management, it decreases availability up 15% because retains soil. Phosphorus levels best reduced expansion space decrease loading combined sewer systems, this trades off against flood, nitrogen suspended solids. The proposed enables spatial prioritisation NBS, may ultimately guide multi-stakeholder decision-making, bridging divide
