This report details a five-year study (2019-2023) of the De Salaberry water retention project in southeastern Manitoba, examining how a small, naturalized dam affects phosphorus reduction to combat eutrophication and harmful algal blooms in Canadian freshwater systems.

A research paper by the Stockholm Environment Institute evaluating the sustainability and economic feasibility of ecotechnologies for recovering carbon and nutrients in Sweden, Poland, and Finland using a bottom-up cost-benefit analysis.

This report, commissioned by the Swedish Agency for Marine and Water Management and led by WSP, examines the feasibility of introducing a trading system for eutrophication in the Baltic Sea region to accelerate recovery efforts and ensure compatibility with EU legislation.

This report describes the release of three baseline SWAT (Soil and Water Assessment Tool) model applications for river basins in Finland, Sweden, and Poland. These models, developed as part of the BONUS RETURN project, are hosted in the Finnish Environment Institute (SYKE) open data repository to allow researchers and practitioners to utilize existing parameterizations or develop new scenarios for these specific catchments.

This report details a multi-criteria analysis (MCA) conducted by the BONUS RETURN project to evaluate the sustainability of various eco-technologies for recovering nutrients and carbon from waste. The study focuses on three catchment areas: Vantaanjoki in Finland, Fyrisån in Sweden, and Słupia in Poland. By engaging local stakeholders to weight sustainability criteria, the report compares baseline management systems against alternatives such as anaerobic digestion, pyrolysis, and source-separation of wastewater.

This report documents the 'Nutrients and Carbon Reuse Challenge,' an open competition launched by the BONUS RETURN project to identify and support emerging eco-technologies capable of recovering nutrients and carbon in the Baltic Sea Region. The document outlines the competition's criteria, the evaluation process conducted by a panel of experts, and the selection of three winning technologies—Biophree, TerraNovaUltra, and Ravita—to enter a pre-commercialization process.

This fact sheet by the Environmental and Energy Study Institute examines the impact of agricultural nutrient runoff—specifically nitrogen and phosphorus—on water quality in the United States, focusing on the Upper Midwest, the Great Lakes, and the Gulf of Mexico. It details the environmental consequences of eutrophication and hypoxia, the legal and regulatory landscape including the Clean Water Act's exemptions for irrigated agriculture, and the role of the USDA's Regional Conservation Partnership Program (RCPP) in funding voluntary conservation efforts to reduce pollution.

This research paper examines the governance challenges facing Uganda's Nile perch fishery in Lake Victoria, highlighting a significant gap between regional policies and local implementation. While the fishery is a critical economic resource and foreign-exchange earner, it is threatened by overfishing, illegal gear, and corruption. The author argues that the sustainability of the resource depends on passing stalled legislation, improving funding models, and strengthening community-based management units.

The International Institute for Sustainable Development proposes a multi-level Water Quality Trading (WQT) system architecture for the Lake Winnipeg Basin to reduce phosphorus emissions and combat eutrophication.

This report examines the risks associated with "peak phosphorus"—the point when demand for rock phosphate exceeds supply—and its implications for global food security and water quality. It focuses on the Lake Winnipeg Basin as a case study for extreme eutrophication and proposes a transition toward phosphorus stewardship through nutrient recovery, recycling, and improved agricultural practices to reduce dependence on mineral fertilizers.

This report presents interim results from a Sustainable Asset Valuation (SAVi) analysis conducted by the International Institute for Sustainable Development (IISD) to develop a business case for the long-term conservation of Lake Dal in Srinagar, India. The analysis evaluates five infrastructure scenarios to address water quality degradation caused by sewage, encroachment, and runoff, comparing their costs, benefits, and impacts on water quality indicators between 2019 and 2060. The project was halted in June 2018 due to the imposition of Governor's Rule in Jammu & Kashmir.

A study by the Stockholm Environment Institute (SEI) Tallinn, conducted as part of the Waterdrive project, analyzed agriculture-related water policy recommendations for the Baltic Sea from 2014 onwards. The research found that a significant portion of recommendations focus on governance but are often too general and lack specific addressees, hindering their effectiveness in combating eutrophication.

This policy brief by the Stockholm Environment Institute examines the implementability of agro-environmental targets in Estonia, focusing on combating eutrophication in the Baltic Sea. It reviews the regulatory framework, the impact of agricultural transitions, and identifies institutional and technical challenges in meeting water and soil quality goals.

This policy brief examines the implementation of agri-environmental targets in Sweden, focusing on efforts to combat eutrophication in the Baltic Sea. It analyzes the roles of various implementing actors, the tension between voluntary and mandatory measures, and the challenges associated with current monitoring and evaluation systems.

This policy note from the World Resources Institute outlines the causes and drivers of eutrophication, noting a significant increase in coastal dead zones and the primary role of human activities—specifically wastewater, agriculture, and fossil fuel combustion—in nutrient pollution.
