Sacramento State webinar: The Future of Water: Will it be there for us? Friday, April 18, 12 pm to 1 pm

Seminar on the future of water by Art Umble via Zoom, April 18, 12-1 PM, hosted by OWP Sacramento State.

 Our global water environment is under stress, creating significant uncertainty about our planet’s ability to support humanity into the future. And the changing climate isn’t helping. As the demand for water continues to grow, meeting demand is no longer just about its scarcity. It’s also about its security because of the socioeconomics of accessibility and equity in water’s numerous consumptive uses across all scales of modern civilization.

This presentation considers the impacts of rapid global urbanization on water, the geopolitical ramifications of water demands across geopolitical boundaries, and the influence of modern agricultural practices on water’s future. To what degree is climate change responsible? What is the role of public policy at the local, regional, and national level in shaping water’s future? What role does the environmental engineering community play in addressing this incredibly complicated challenge? Are there feasible, practical, cost-effective technical solutions that will ensure a sustainable future where water will be available, safe, and secure? Link to Zoom registration.

CA Water Data Consortium Webinar – April 23, 2025

Join us on Wednesday, April 23, for an exploration of "riverine heat waves" — those concerning periods of unusually warm water temperatures that stress river ecosystems and threaten aquatic species. Jonathan Walter from the University of California Davis Center for Watershed Sciences will share eye-opening research showing how these warming events have doubled in frequency over the past 25 years. You'll discover how climate patterns and water management decisions create critical cool refuges during hot periods, and gain practical insights for protecting aquatic species when our rivers need it most. Register now for this timely Earth Month discussion. Register Here
