Incentivizing Multibenefit Outcomes in Surface and Groundwater Markets

This research highlight explores how water markets can be designed to achieve environmental and economic benefits simultaneously. While water markets can help reallocate scarce water resources among users, they may also create secondary impacts such as reduced instream flows, groundwater depletion, or habitat degradation. The study expands the Open Water Trade smart market algorithm to include targeted third-party incentive payments that encourage trades producing environmental benefits.

Using applications in Washington’s Yakima Basin and California’s San Joaquin Valley, the model demonstrates how small payments from an environmental buyer can influence trade patterns to increase instream flows or reduce groundwater pumping near sensitive habitats. The results show that incentive-based approaches embedded in smart market systems can mitigate environmental impacts at lower cost than direct regulatory restrictions. This approach provides a flexible policy tool for managing water scarcity while supporting ecosystem protection and water market participation.
