… Climate change has exacerbated shortages, with studies indicating that recent Colorado River flows are near their lowest in at least 2,000 years. That has had severe consequences for fish: Of the 49 fish species native to the Colorado River Basin, 44 are already threatened, endangered or extinct. … New research led by University of Washington water policy expert Philip Womble found that a market-based approach to managing water could provide more reliable supplies for farmers, communities and industry. The right market design and a little extra investment could also help threatened fish species. The study, published June 20 in Nature Sustainability, details a new system for leasing rights to water from the basin while reallocating some water to imperiled habitats. Among the paper’s most substantial findings, researchers estimate that strategically spending 8% more than under the cheapest water conservation program could nearly triple the ecological benefits.
