A Vision for More Sustainable Farmlands

/in , /by /High Country Newsby Theo Whitcomb

From above, California’s San Joaquin Valley spills out of the Sierra Nevada in a checkerboard of earth-toned farmland. It’s some of the most valuable land in the world; every year, the agribusiness industry here produces billions of dollars’ worth of milk, vegetables and nuts. But the scale, and the industrial intensity, of agriculture require an enormous amount of groundwater to be pulled out of aquifers deep belowground — more than the industry can afford to pump, according to hydrologic modeling.

According to projections from the Public Policy Institute of California, between 535,000 and 750,000 acres — around 15% of the valley’s irrigated farmland — will need to be taken out of irrigated production in order to meet the requirements of the state’s Sustainable Groundwater Management Act.

Parts of SoCal to See First Rain of February. Here’s When and Where

/in , , /by /NBC Los Angelesby Accalia Rositani

Cooling down from weekend highs in the 90s, Los Angeles County has a chance for rain on Tuesday, its first in February.

An onshore flow Monday evening will start to push high clouds east, bringing cooler air to drop Tuesday’s temperature by 16 degrees. Monday’s highs are expected to be in the 70s and low 80s.

Showers will be scattered and light, with accumulations no more than 0.10 inch, but areas closer to the foothills might see up to an inch. The light precipitation will continue through the day Tuesday, drying up Wednesday morning.

This comes as the majority of LA County continues to experience a moderate drought, with the northernmost areas and neighboring Kern County experiencing a severe drought.

The Drought in the Western U.S. Could Last Until 2030

/in , , /by /National Geographicby Alejandra Borunda

There have been brief moments of reprieve in the drought that has stretched on since 2000 in the western United States—a water-rich 2011, a snow-laden 2019—but those breaks have only highlighted the more dramatic feature of the last few decades: unrelenting dryness.

Without human-driven climate change forcing Earth’s temperatures up, the ongoing drought would still be painful and parched. But it would be unexceptional in the grand scheme of the past 1,200 years. A new study in Nature Climate Change shows that Earth’s warming climate has made the western drought about 40 percent more severe, making it the region’s driest stretch since A.D. 800. And there’s a very strong chance the drought will continue through 2030.

Opinion: Will Salton Sea Lithium Dreams Come True? It Will Be Years Before We Know

/in , , /by /Desert Sunby Desert Sun Editorial Board

The underground chemical stew beneath the Salton Sea is believed to hold enough lithium to power millions of cars and homes with green energy. But only if — a big if — enough of that scalding “geothermal brine” can be brought to the surface and the lithium sifted out.

That’s an incredibly complex process. And it’s just about as hard for those who live around the sea to separate reality from dreams when it comes to the impact of all that lithium.

In the best case, we’ve heard over the years, a lithium boom could generate billions of dollars; bring thousands of badly needed jobs for those living near the sea; spur an environmental revival; and give clean energy to a region, the state and beyond.

Floating Solar Panels Could Be the Next Big Thing in Clean Energy

/in , , /by /Popular Scienceby Thor Benson

Solar panels can be placed on your roof, on a plot of land, or basically anywhere else where they  are anchored to something solid. That said, there are only so many solid spaces available to install them. To beat climate change, our electricity mix is going to need a lot more renewable energy systems to take over fossil fuels.  Many in the solar industry are looking for a new home for solar panels—possibly even floating on water.

Floating solar farms have been around for over a decade, but water-bound panels became much more prominent in the last few years. The basic idea is to attach solar panels to plastic floats which then drift on a body of water.

One Colorado Farmer Is Going Against the Grain to Use Less Water. It’s Working.

/in , , /by /The Colorado Sunby Chris Outcalt

On a chilly morning 5 miles north of Fruita, Lowell King, standing at the edge of a cornfield, reaches down, grabs a clump of dirt, and starts tearing at the soil with his meaty fingers. King eventually points to a tiny white spot in the dirt. “Anytime you can see stuff almost like that mold right there, that’s fungi,” he says. “And there’s all this other good stuff, and these roots intertwined; that’s what increases your water infiltration.”

King, who’s been farming in the Grand Valley since 2005, is illustrating an important principle of a concept known as regenerative agriculture — a technique he says could help Colorado stretch its dwindling water supplies. But adopting that philosophy also requires rejecting deeply entrenched conventional farming methods, such as tilling fields to prepare the ground for planting.

Despite Dry Winter and Drought Status, San Diego County Water Supply Is Steady

Quoted: San Diego County Water Authority

Despite San Diego County currently sitting at ‘moderate drought’ status and February bringing no rain so far, the San Diego County Water Authority (SDCWA) says the local water supply is safe.

According to SDCWA Water Resources Manager Jeff Stephenson, they have analyzed the current supply and feel confident that there will not be any water shortages for at least a five-year period because of their preparedness, even if drought status remains.

“We’ve spent 30 years diversifying those supplies so that we have seven, eight different sources of water in the region, so there’s no danger of running out,” said Stephenson.

Proposed San Vicente Reservoir Hydro Facility Project Aims to Meet Energy Goals

Quoted: San Diego County Water Authority

The leader of a conservation group opposes the idea of building this facility since it could be built on two preserves. Friday, the San Diego County Water Authority explained why it’s beneficial for California.

Neena Kuzmich from the San Diego County Water Authority says the proposed hydro energy storage facility at the San Vicente Reservoir will not only generate power for thousands of households, it will help California meet its energy goals.

“The state has an aggressive renewable state goal with 100% by 2045. With clean energy, this project will help in meeting these goals. It will use renewable energy during the day for later use and it does not emit greenhouse gases,” said Kuzmich.

Where California’s Key Reservoirs Stand After the 2nd Driest January Ever

/in , , /by /SF GATEby Amy Graff

California hasn’t seen rain in over a month, and some of the state’s key reservoirs are starting to be impacted.

Shasta Lake, the state’s largest reservoir, was at 54% of its historical average as of Feb. 9, compared to 72% last year, the California Department of Water Resources said. San Luis Reservoir on the eastern slope of the Diablo range is at 59% of its historical average, compared to 71% last year.

Other reservoirs are up from where they were at this time last year.

“This would be expected given that last year was the 2nd driest year for CA in our observed record and the 2020-2021 two year period set a new record for dryness,” Michael Anderson, the state climatologist for the Department of Water Resources, wrote in an email.

California Sizzles in February Heatwave

/in , , /by /phys.orgby Paula Ramon

A heatwave was bringing unseasonably high temperatures to California on Thursday, sending sun-worshippers to the beach, but also sparking a brushfire.

Forecasters issued a heat warning for the most populous US state through to Sunday, warning the mercury could hit a height-of-summer 90 Fahrenheit (32 Celsius) in Los Angeles, well above the average for winter.

California, in common with much of the western United States, is enduring a historic drought and wild swings in weather that scientists say is exacerbated by man-made climate change.

“If you warm the planet, you’re going to break heat records,” said geographer Justin Mankin of Dartmouth College.
