California Spent Decades Trying to Keep Central Valley Floods at Bay. Now It Looks to Welcome Them Back

Land and waterway managers labored hard over the course of a century to control California’s unruly rivers by building dams and levees to slow and contain their water. Now, farmers, environmentalists and agencies are undoing some of that work as part of an accelerating campaign to restore the state’s major floodplains.

Green Infrastructure Can Be Cheaper, More Effective than Dams

Hundreds of studies on nature-based solutions to extreme events show that “green infrastructure” is often cheaper and more effective than engineered projects like dams, levees and sea walls, according to a new analysis.

Can Carbon Credits Save Sacramento-San Joaquin Delta Islands and Protect California’s Vital Water Hub?

The islands of the western Sacramento-San Joaquin Delta are sinking as the rich peat soil that attracted generations of farmers dries out and decays. As the peat decomposes, it releases tons of carbon dioxide – a greenhouse gas – into the atmosphere. As the islands sink, the levees that protect them are at increasing risk of failure, which could imperil California’s vital water conveyance system.
