In recent years, wildfires in the western United States have occurred with increasing frequency and scale. Climate change scenarios in California predict prolonged periods of drought with potential for conditions even more amenable to wildfires. The Sierra Nevada Mountains provide up to 70% of the state’s water resources, yet there is little known on how wildfires will impact water resources in the future.
A handful of US states – including New Mexico and California – are facing significant strains on their water supplies that will only intensify with global heating, according to new rankings. New Mexico tops the list and is the only state with “extremely high” pressures on its water availability. The state’s score is on par with the United Arab Emirates in the Middle East and Eritrea in Africa, the World Resources Institute (WRI) found. California ranks second, followed by Arizona, Colorado and Nebraska. “We’re stretching our water supply pretty much as far as it can go … and even further,” said Leah Schleifer, a spokeswoman for WRI’s water program. Experts with WRI said the data shows a global water crisis. “The picture is alarming in many places around the globe, but it’s very important to note that water stress is not destiny,” said Betsy Otto, WRI’s global water director. “What we can’t afford to do any longer is pretend that the situation will resolve itself.”
A series of interconnected decisions this summer could affect water availability for years to come. As Farm Bureau has reported through the years, several fish species in the Sacramento-San Joaquin Delta and its tributaries are protected as either “threatened” or “endangered” under both federal and state endangered species laws. As a result, projects and activities that could potentially affect these species require a permit. For many years, federal “biological opinions” for delta smelt and winter run chinook salmon have dictated restrictions on operations of the pumps, reservoirs and canals of the federal Central Valley Project and State Water Project—major water works that “move the rain” from Shasta clear to San Diego.
Looking back 40 years, Jeff Stone said the greenhouse and nursery industry was barely a blip on the radar of Oregon agriculture. Now nursery stock is consistently among the state’s most valuable farm commodities, with sales of $947 million in 2017. Stone, executive director of the Oregon Association of Nurseries, said the momentum really took off in the 1980s and 1990s. Based in Wilsonville, about 15 miles south of Portland, the association represents 800 members, including 600 growers. It is a success story driven by the availability of water, along with the Mediterranean climate — cool, wet winters followed by hot, dry summers — and rich soils of the Willamette River Basin.
