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.

This Sustainable Asset Valuation (SAVi) report assesses the economic and environmental impact of nature-based infrastructure (NBI) and hybrid infrastructure interventions in the Bogotá River basin, concluding that these investments provided significant net benefits in flood protection and water quality.

A SAVi assessment of the SUNCASA project in Johannesburg's Jukskei River catchment finds that nature-based solutions—including riparian restoration of 469 hectares and planting 46,000 trees—will generate USD 8.6 million in net benefits over 25 years. The highest return comes from improved water quality, which is expected to save USD 3.7 million in health costs.

This executive summary describes a spatial targeting strategy developed by the International Institute for Sustainable Development (IISD) to optimize the placement of water retention projects, such as wetlands and small naturalized dams, to reduce phosphorus loading in Canadian Prairie watersheds.

A research paper based on a survey of global and regional experts regarding the governance of the Guarani Aquifer System in South America, focusing on regulation, resource ownership, and the state of groundwater quality and quantity.

A research paper by the Inter-American Institute for Global Change Research detailing a survey of state agency officials regarding groundwater governance in the United States, highlighting fragmented legal frameworks and shared priorities.

This executive summary describes a project led by the Inter-American Institute for Global Change Research to establish the Nitrogen Human Environment Network (Nnet). The project aims to map the nitrogen (N) cycle across Latin America, analyzing the impacts of human activities—such as fertilizer use, soy production, and mining—on ecosystem processes and biodiversity to provide guidelines for regional nitrogen management policies.

This executive summary describes a project aimed at quantifying how inland activities and climate change impact coastal resources in several Caribbean island nations. The project utilizes hydrological modeling of 84 catchments to analyze the flow of water, sediments, and contaminants to coastal ecosystems to support sustainable management and restoration.

The 'Essential Monitor’s Guide for Prairie Water Retention' is a technical guidebook published by the International Institute for Sustainable Development (IISD) in February 2024. It provides a framework for monitoring the water quantity and quality of water retention projects—natural infrastructure designed for flood and drought mitigation, water quality improvement, and biodiversity enhancement. The guide details the necessity of water and contaminant mass balances, recommends specific monitoring tools and equipment, and explains how to use rating curves and automated samplers to collect data in the challenging environments of the Canadian Prairies.

This briefing by the Environmental and Energy Study Institute (EESI) describes the USDA Natural Resources Conservation Service’s (NRCS) Regional Conservation Partnership Program (RCPP). The program coordinates conservation activities with partners to address natural resource concerns on a regional or watershed scale, with a specific focus on implementing practices that mitigate climate change.

This report by the International Institute for Sustainable Development (IISD) evaluates the costs and economic benefits of 10 water retention projects implemented between 2014 and 2020 in the Seine Rat Roseau Watershed District of Manitoba. The analysis finds that for livestock producers, the average benefit-cost ratio is 3.16, with benefits including improved water quality, extended grazing, and reduced operational costs. While most projects showed a positive return on investment, those on crop-only farms were more likely to have costs outweighing benefits due to high upfront construction expenses.

This briefing note from the Canadian Association of Physicians for the Environment outlines priority amendments to Bill S-5, which aims to modernize the Canadian Environmental Protection Act, 1999 (CEPA). The document advocates for strengthening the right to a healthy environment, improving transparency regarding harmful chemicals in consumer products, and establishing strict timelines for chemical assessments and risk management to protect public health and the environment.

This report details a Sustainable Asset Valuation (SAVi) assessment of wastewater treatment infrastructure options for the Hartenbos estuary in South Africa, evaluating their impact on water quality, nutrient loads, and potential for agricultural water reuse.

This policy brief argues that Community-Based Water Monitoring (CBWM) is a cost-effective and scientifically rigorous method for collecting long-term water quality data across Canadian watersheds. It advocates for a shift from short-term competitive grants to long-term core funding to prevent the loss of technical capacity and the creation of 'dark data' that cannot be used for policy decisions.

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.

The Centre for Environmental Rights, acting for the Vukani Environmental Justice Movement in Action (VEM), wrote to Minister Lindiwe Sisulu on 9 April 2020 to demand urgent water provision for communities in and around eMalahleni. The letter highlights that several areas have lacked reliable water since September 2019, forcing residents to use contaminated streams, which increases health risks during the COVID-19 pandemic.

This research paper assesses the combined impacts of climate change and mining activities on streamflow and heavy metal loading in the Chindwin River, Myanmar, using hydrological and geochemical modelling.

This technical note describes the Aqueduct 3.0 water risk framework, which aggregates 13 indicators—covering quantity, quality, and reputational risks—into a composite overall water risk score to help decision-makers identify high-risk regions or assets.

This report applies the Sustainable Asset Valuation (SAVi) methodology to evaluate ecological restoration options for South-West Beira Lake in Colombo, Sri Lanka, focusing on the economic impacts on property values and recreational spending.

This briefing describes the use of open spatial data to identify environmental 'hotspots' in Manitoba to optimize the allocation of limited resources for water quality, sustainable agriculture, and carbon sequestration.
