The AgWater Challenge, launched in October 2016 by WWF and Ceres, engages food and beverage companies in reducing water risks in their supply chains. The inaugural cohort of seven companies committed to measurable goals across five stewardship 'ingredients': risk assessment, sustainable policies, time-bound goals, watershed collaboration, and farmer support. While companies showed progress in risk assessment and policy setting, supporting growers remains a significant challenge. Key participants like PepsiCo, Diageo, and Kellogg have implemented specific targets for water efficiency and sustainable sourcing, emphasizing the need for senior management buy-in and holistic risk management.

The 2016 Orinoco River Basin Report Card evaluates the health of various sub-basins in Colombia, assigning an overall grade of B- (63%). The assessment reveals a strong west-east gradient, with Andean headwaters in the west facing severe degradation from mining, oil and gas, and agro-industry, while eastern sub-basins like the Matavén (Grade A) remain more intact. Key concerns include poor human nutrition in the Inírida basin and significant data gaps in water quality monitoring and biodiversity surveys across several tributaries.

WWF and the University of Maryland’s Center for Environmental Science (UMCES) are implementing a standardized process to create freshwater basin report cards. These tools synthesize complex data into accessible grades to empower stakeholders and improve management. The process involves six steps: stakeholder engagement, indicator selection, threshold definition, scoring, communication, and score improvement. A 2016 case study of Colombia’s Orinoco River Basin, which received a B-minus grade, demonstrates the model's application in addressing threats like land-use change and extractive industries.

The report examines 'water balance' goals, where companies aim to restore a volume of water equivalent to what they consume. While these goals provide clear communication and incentive for action, the document argues that they must be grounded in local basin contexts and collective action to avoid 'greenwashing' and effectively mitigate physical, regulatory, and reputational risks. It highlights the transition toward 'context-based targets' aligned with Sustainable Development Goal 6.

The report examines the fragmentation of watershed data collection in Canada, where varying methodologies across municipal, provincial, and international borders hinder a coherent understanding of watershed health. Through webinars and workshops conducted by the Canadian Sustainability Indicators Network (CSIN) in 2014–2015, the report identifies key obstacles such as imbalanced institutional capacities and the lack of standardized guidance for indicator selection. It provides recommendations for improving indicator frameworks, including the integration of social and economic data, the use of metadata to enhance comparability, and the adoption of staggered reporting to make information more digestible. The document also notes a tension between the desire for national consistency and the risk of using a 'least common denominator' approach that may sacrifice local data resolution.

The report evaluates a wide array of in-lake remediation techniques to combat eutrophication, emphasizing that these methods are generally only effective if external nutrient loads are simultaneously reduced. It categorizes treatments into biological engineering (e.g., biomanipulation, floating wetlands), physical engineering (e.g., hypolimnetic withdrawal, dredging, artificial circulation), and chemical applications (e.g., alum, Phoslock, algicides). The document provides detailed case studies from North America and Europe, analyzing the effectiveness, longevity, and costs of each method, while highlighting the critical role of internal phosphorus loading in delaying lake recovery.

The briefing discusses the importance of integrated policy approaches for regional sustainable development, specifically focusing on river basins and deltas. It highlights the Tennessee Valley Authority (TVA) as a model of integrating economic growth with environmental protection and discusses the transition toward a green economy. The text also references the 'Green Lake Friendly' initiative in Canada and China's national policies on ecological civilization to emphasize the need for policy coherence across different jurisdictions.

The report details a USAID-funded project led by the Stockholm Environment Institute to integrate climate change considerations into Colombian water management. By deploying the WEAP modeling system and a participatory RDS process in the Otún, La Vieja, and Alto Magdalena watersheds, the program built technical capacity within regional environmental authorities (CARs) and academic institutions. Key findings include the critical role of páramo ecosystems in maintaining dry-season baseflows and the potential for hydropower development to disrupt downstream wetland dynamics in the Magdalena-Cauca basin. The project emphasizes moving from 'conscious incompetence' to 'conscious competence' in climate adaptation planning through institutional capacity building and the creation of a professional community of practice.

The 'Ríos del Páramo al Valle' project (2012-2015) focused on enhancing the adaptive capacity of Colombia's regional environmental authorities (CAR) in managing water resources under climate uncertainty. By implementing the Robust Decision Support (ADR) framework and the WEAP modeling system, the project provided technical tools and capacity building across several key basins: the Otún, La Vieja, Alto Magdalena, and the broader Magdalena-Cauca macro-basin. Key outcomes include the identification of basin-specific adaptation strategies—such as páramo conservation in the Otún and wastewater treatment in La Vieja—and the development of new WEAP functionalities to model floodplain dynamics and hydrological alteration. The project emphasized a gender-inclusive approach and the creation of a regional community of practice involving universities and government agencies like IDEAM to ensure the long-term sustainability of climate-informed water planning in Colombia.

The report argues that achieving sustainable groundwater management in California requires the establishment of clear, quantitative measurable objectives to avoid 'undesirable results' such as land subsidence and seawater intrusion. It advocates for an adaptive management approach involving clear baselines, quantitative thresholds, and protective triggers. The authors propose a six-step preliminary framework for setting thresholds and recommend that the state develop a common framework to ensure consistency in data, assumptions, and metrics across different groundwater sustainability agencies.

The report examines the role of Netley-Libau Marsh in mitigating phosphorus overloading in Lake Winnipeg. It finds that total phosphorus concentrations in the marsh significantly exceed Manitoba Water Quality Guidelines. The study estimates current phosphorus and nitrogen storage in plants and sediment, suggesting that a 25 per cent restoration of cattail and other marsh plants could increase storage potential by 130 tonnes of phosphorus and 500 tonnes of nitrogen.

The document details the methodology for the Aqueduct Water Risk Atlas Global Maps 2.1, which updates the 2013 version by incorporating GLDAS-2 NOAH v. 3.3 runoff data. It outlines 12 indicators categorized into physical risk (quantity and quality) and regulatory and reputational risk. The framework utilizes a combination of public domain data, literature reviews, and original datasets to estimate water availability and use at the hydrological catchment scale. Key metrics include baseline water stress, inter-annual and seasonal variability, flood and drought severity, and groundwater stress, alongside socio-economic indicators like media coverage and access to water.

The document details the construction of the Aqueduct Water Risk Atlas, which uses a composite index approach to map global water risks. It describes the development of six modeled indicators (baseline water stress, inter-annual variability, seasonal variability, upstream storage, return flow ratio, and upstream protected land) and the adaptation of six externally sourced indicators (flood occurrence, drought severity, groundwater stress, media coverage, access to water, and threatened amphibians). The methodology involves using an ensemble of regression models to project water withdrawals to 2010, spatial disaggregation to the catchment scale, and a catchment-to-catchment flow accumulation approach for water supply. The final water risk scores are generated through a linear weighted aggregation process, allowing users to customize weights based on their specific sector or risk sensitivity.

The report investigates water constraints in the Berg Water Management Area (WMA) and Saldanha Bay, South Africa. It finds that traditional linear planning—based on generalized growth percentages—fails to account for the 'stepped' water demand of large industrial projects, potentially leading to supply shortfalls between 2017 and 2019. The document argues for a 'smart' allocation model that links water productivity (GDP/jobs per drop) to resource allocation and explores a Water Exchange Network (WEN) to reduce freshwater intake by up to 15% through industrial water cascading. It also highlights that high salinity in the Berg River poses a significant operational cost and production risk to the steel processing industry in Saldanha.

The report highlights Lake Winnipeg's extreme vulnerability to upstream pressures due to its very low volume relative to its massive drainage basin. It argues that managing the lake in isolation is insufficient and recommends a transboundary, basin-wide framework that treats land as 'ecological infrastructure.' By implementing distributed storage and wetland restoration, the region can mitigate floods, capture nutrients, and buffer against climate change while supporting hydroelectric generation. The document draws on case studies from the Columbia River and Murray-Darling basins to illustrate how integrated water resources management (IWRM) and ecosystem services can balance competing economic and environmental needs.

The report evaluates water consumption in peach and plum orchards in the Western Cape, finding that while South African farmers are significantly more water-efficient than global averages, local improvements are possible through better irrigation scheduling and the adoption of drip irrigation over micro-sprinklers. It also details a pilot project testing the AWS standard across nine farms, identifying drought, social risks (theft), and regulation as primary concerns for farmers, and recommending the alignment of the AWS standard with other agricultural certifications like GlobalGAP.

The document argues that agricultural management is overly driven by food production, leading to a decline in the ecosystems it depends on. It advocates for an ecosystem-based approach to food security and introduces semantic meta-modelling as a tool to integrate various models and quantify trade-offs between crop yields and regulating services like water quality and climate regulation. Using a case study in the Basque Country, the authors demonstrate that informed farming practices, such as adjusting manure application and reducing tillage, can significantly reduce emissions and nitrate leaching without necessarily compromising winter wheat yields.

The briefing outlines the 'From Farms to Regions' project, which used a participatory framework and the Envision geospatial modelling platform to develop climate adaptation strategies for southeastern Ontario. By engaging stakeholders and analysts, the project identified key drivers of change—climate change, markets, and governance—and created five future scenarios (Business-as-Usual, Targeting foreign markets, Promoting the bioeconomy, Moving towards greener agriculture, and Living locally). These scenarios were used to quantify impacts on land use and environmental indicators, leading to the identification of over 50 adaptation actions clustered into farm-level changes, new insurance mechanisms, ecosystem service support, information tools, and public education. The document concludes with a framework for monitoring the integration of these adaptation measures into cross-sectoral policy and planning.

The document outlines a framework for mainstreaming climate change adaptation by combining stakeholder engagement with quantitative spatial modelling. Using the 'Farms to Regions' (F2R) project in Eastern Ontario as a case study, it describes a process of identifying regional drivers, developing qualitative and quantitative scenarios (including a Business-As-Usual baseline), and simulating these futures using the Envision modelling platform. The guide emphasizes the use of integrated decision units (IDUs) to map impacts on farm income and environmental services, providing a toolkit for planners to evaluate trade-offs and develop robust adaptation strategies.

A World Resources Institute (WRI) analysis finds that the U.S. Department of Agriculture (USDA) could achieve seven to 12 times more environmental benefits for the same budget by combining geographic and benefit-cost targeting for water quality improvements. Currently, only about $335 million of the $5 billion annual federal conservation budget is spent on controlling soil erosion and fertilizer runoff. The analysis shows that nitrogen pollution reductions could increase from 91 million pounds annually at $3.65 per pound to 1.1 billion pounds at $0.30 per pound through optimized targeting. However, technical gaps in identifying cost-effective acres, the voluntary nature of programs, and political resistance to shifting funds act as barriers. WRI recommends quantifying environmental benefits, incorporating benefit-cost principles into planning tools, conducting pilot projects, and revisiting state funding allocation formulas.
