Quantifying the Potential Benefits of Land Conservation on Water Supply to Optimize Return on Investments uses economic valuation to determine specific spatial areas for conservation and development in the Catawba-Wateree Watershed. Using spatial models, potential conserved areas that would create the largest benefits were identified based on their reduction in sediment load. Other valuations such as air quality improvements from forest management are also considered.

Green Infrastructure: Guide for Water Management examines case studies of green infrastructure projects throughout the United States. The report argues that a lack of awareness of the solutions and additional cost benefits that green infrastructure projects can provide is the major barrier to implementation of green infrastructure solutions. The case studies include green infrastructure projects such as green roofs, permeable pavement, levee setbacks, wetland conservation and construction, reforestation and afforestation, and flood bypasses and coastal protection. The case studies cite benefits from the ecosystem service categories (i.e., provisioning services, regulating services, cultural services, habitat or supporting services), providing a qualitative discussion of primary benefits and co-benefits for each case study.

Public Private Partnerships and Finance of Large-Scale Green Infrastructure in the Great Lakes Basin is a report presenting the outcome of an initiative to implement “large-scale” green infrastructure projects using private financing and/or private delivery in the Great Lakes Basin. “Large-scale” is defined as a green infrastructure project that requires an investment of at least $50 million in a particular region. The report identifies main economic and regulatory drivers for green infrastructure, as well as presents a decision tree as a tool to help communities decide if private financing is appropriate for their needs.

Assessing the Return on Investment in Watershed Conservation applies a return on investment (ROI) framework to a watershed conservation project in Santa Catarina, Brazil. The framework involves quantification of the relationships between 1) intervention, 2) ecosystem structure, 3) ecosystem function, 4) ecosystem service, 5) benefit, and 6) values and program cost. The report illustrates that restoring source watersheds is a cost-effective way to reduce drinking water treatment costs, improve water supply resilience, and protect biodiversity. The ecosystem services quantified in the study include sediment concentrations at water treatment intake, which when reduced can lead to avoided peak season water loss, avoided use of chemicals, avoided dry sludge landfilling, and avoided pumping. The report also includes costs for landowner engagement and interventions, as well as land rentals.

Quantifying Watershed Restoration Benefits in Community Water Partnership Projects is a report that aims to quantify water-related benefits of Coca-Cola Company watershed protection, water for productive use, and water access projects. The report identifies nine categories of watershed restoration actions, including agricultural land practice changes, stormwater management, land use/land cover alterations, hydraulic/hydrologic waterbody alterations, recaptured leakage from water systems, wastewater treatment, biologic management, water reuse, and rainwater harvesting and aquifer recharge. The benefits quantified within this report include water quantity and water quality (i.e., sediment reduction), and the benefits not quantified include habitat improvement, biodiversity, and carbon sequestration.

Impacts of forest restoration on water yield: A systematic review provides an academic review of 666 journals and studies conducted on the impact of forest restoration on water yields. From the works reviewed, forest restoration generally led to decreases in water yields, baseflow, and groundwater temporarily. The report suggests that green water may increase from reforestation, but there is little evidence to suggest that blue water will increase from reforestation.

The California Water Plan presents a guide on water management strategies that can provide multiple benefits both regionally and statewide in California. The management strategies are organized by goals, such as reducing water demand, improving operational efficiency, or improving water quality, and the benefits are categorized under water supply, drought preparedness, water quality, operational flexibility, flood impacts, environmental benefits, energy benefits, recreation, and groundwater overdraft risk. The report also includes guidance on the quantitative analysis of multiple benefits for policymakers and water resource managers.
