Should farm fields be used for crops or solar? MSU research suggests both

“As farmers debate whether fields should be used for agriculture or solar panels, new research from Michigan State University says the answer could be both.   Jake Stid, a graduate student in the College of Natural Science Hydrogeology Lab, analyzed remote sensing and aerial imagery to study how fields have been used in California for the last 25 years. Using databases to estimate revenues and costs, Stid found that farmers who used a small percentage of their land for solar arrays were more financially secure per acre than those who didn’t.   His research, now published in Nature Sustainability, could provide a new roadmap to solvency for farmers struggling to pay the bills. Instead of converting entire fields to solar arrays, Stid hopes this research will help more farmers decide to keep producing crops by strategically placing arrays on lower-yield spots in their fields.  “The conversation shouldn’t be as much about solar or agriculture, but solar and agriculture,” Stid said. “They can work together, and it can be a collaboration rather than a conflict.” … ” Read more from Michigan State University.

DWR developing plans to protect SWP infrastructure from invasive golden mussels

“The California Department of Water Resources (DWR) is developing plans in order to protect California’s waterways from the spread of the invasive golden mussel.  A spokesman with the Department of Water Resources said that watercraft inspections at Lake Oroville and surrounding State Water Project facilities are set to begin within the next month.  Officials say that golden mussels, which first appeared in the waters of California in October 2024, pose a significant threat to the state’s water systems. These mussels could impact water quality and infrastructure if not controlled.  Golden mussels range from three-quarters of an inch to two inches in size and have yellowish-brown shells. They reproduce quickly and spread easily through infested waters. … ”  Read more from Channel 12.

Desert reservoirs found to trap organic carbon in sediment

“In 2021, while revelers across America celebrated the fourth of July, three researchers waded through a shallow river delta in the New Mexican desert. PhD student Abby Eckland (now graduated), INSTAAR faculty fellow and associate professor of geological sciences Irina Overeem and postdoc Brandee Carlson (now University of Houston) stood in what remained of the Rio Grande—years of drought had shrunk the river to a few small channels. Just downstream, the channels entered the Elephant Butte Reservoir—New Mexico’s largest.  Then, all of the sudden, the water started rising. First, to the scientists’ calves. Then above their knees.  The river became muddy and turbid. Debris—tamarisk leaves, pine needles and trash—floated down the widening channel. Dead fish rose to the surface and came to rest in the weeds on the riverbank. It was a flash flood.  At this point, a normal sightseer would probably head for the hills, but the scientists, instead, responded with excitement. This was an opportunity for inquiry into an ephemeral natural phenomenon. Eckland bottled up water samples while Overeem and Carlson checked on the sensing equipment they had placed in the river that morning. … ”  Read more from the University of Colorado at Boulder.

4 California critters making a comeback with help from UC researchers

“The mountain yellow-legged frogs of Yosemite National Park are in an epic fight for survival. Theirs is a tale of devastation and redemption, luck and suspense, and amphibians in helicopters.  And in an era of grim headlines about the state of nature, a recent UC study about them offers a rare glimmer of hope: These frogs, which were plagued nearly to extinction by a deadly fungus just a few years ago, are now poised for a comeback.  This Earth Day, we’re celebrating stories from the past year of UC research that illustrate the resilience of life on our planet and demonstrate the power of humans to help solve problems of our own making.  Once the most abundant amphibian in California’s high mountain lakes, the mountain yellow-legged frog has lately fallen victim to a fungus called Batrachochytrium dendrobatidis, or Bd.  From its origins in Asia, Bd has spread around the globe, an accidental byproduct of “human commerce and our propensity to move things from one place to another,” says UC Santa Barbara biologist Roland Knapp, who has devoted the past 20 years to helping the species endure Bd. … ”  Read more from the University of California..

We used to agree on Earth Day. Political division has changed the environmental priorities

“This year marks the 55th anniversary of Earth Day, but rather than enjoying its golden years, the planet is facing a new kind of peril. In recent weeks, the Republican party — the same party that oversaw the creation of the eco-conscious holiday back in 1970 — has delivered considerable blows to the environment, including taking steps to undo critical Nixon-era policies that protect the nation’s air, water, natural lands and threatened species.  President Nixon presided over the first Earth Day, founded in large part as a reaction to a devastating oil spill off the coast of California. Nixon and his wife, First Lady Pat Nixon, planted a tree on the White House lawn to commemorate the occasion.  The holiday ushered in a decade of environmental activism and legislation under his conservative leadership, including the creation of the U.S. Environmental Protection Agency and the signing of the Clean Air Act in 1970; the Clean Water Act in 1972; and the Endangered Species Act in 1973.  Now the landscape looks considerably different. … ”  Read more from the LA Times. | Read via Yahoo News.

Meet the seed collector restoring California’s landscapes – one tiny plant at a time

“Deep in California’s agricultural heartland, Haleigh Holgate marched through the expansive wildflower-dotted plains of the San Luis national wildlife refuge complex in search of something precious.  She surveyed the native grasses and flowering plants that painted the Central valley landscape in almost blinding swaths of yellow. Her objective on that sweltering spring day was to gather materials pivotal to California’s ambitious environmental agenda – seeds.  “Over there it’s a brighter yellow, so I know those flowers are still blooming, rather than going to seed production,” she noted. “Versus over here, it’s these hues of deeper reds and deeper gold. That seed is ready.” As a seed collection manager with the non-profit Heritage Growers native seed supplier, Holgate is tasked with traveling to the state’s wildlands to collect native seeds crucial for habitat restoration projects. … ”  Read more from The Guardian.

Dan Walters: California’s economy was already sluggish before Trump’s global tariffs

“Last week, Gov. Gavin Newsom and Attorney General Rob Bonta filed a lawsuit challenging the legality of President Donald Trump’s broad imposition of tariffs on imported goods.  “President Trump’s unlawful tariffs are wreaking chaos on California families, businesses, and our economy, driving up prices and threatening jobs,” Newsom said in a statement.  The tariffs could have all of those negative impacts, but California’s economy was already sluggish.  As Gabe Petek, the Legislature’s budget analyst, said in a January response to Newsom’s state revenue forecast, “These gains are not tied to improvements in the state’s broader economy, which has been lackluster, with elevated unemployment, a stagnant job market outside of government and healthcare, and sluggish consumer spending.” … ”  Read more from Cal Matters.

California can’t wait for the political winds to shift. My bipartisan wildfire bill would save lives.

Senator Alex Padilla writes, “No matter how many times you’ve seen it, nothing can prepare you for the devastation you find in the aftermath of a wildfire.  Nothing.  I’ve visited the Forest Service’s Incident Post in Quincy as fire crews battled the raging Dixie Fire in 2021.  And I toured what’s left of the Pacific Palisades and Altadena neighborhoods that were hit worst by this winter’s fires. What I’ve seen is heart wrenching.  Car wheels melted into the sidewalk.  A sea of embers and ashes, interrupted only by chimneys and fireplace mantels where family photos once rested.  In some cases, brick sidewalks and doorways that once led to baby cribs and kitchen tables, that now lead to nowhere.  No one could walk away after seeing what I’ve seen, year after year in California, and still deny the threat of climate change.  We have to do more. … ”  Read more from the LA Daily News.

Local agencies condemn IEUA’s rushed rate hike vote, cite lack of transparency and accountability

“In a stunning disregard for public opposition and local economic realities, the Inland Empire Utilities Agency (IEUA) voted unanimously last Wednesday to approve an 18% rate hike, spread over two years, despite clear opposition from multiple member agencies, concerns from the public, calls for more transparency, and requests for more time to study the matter.  In a joint statement, local agency leaders for Chino, Montclair, Monte Vista Water District, and Ontario called IEUA’s vote “deeply disappointing and procedurally flawed,” pointing to the agency’s refusal to grant additional time for review, or to meaningfully collaborate with the cities and agencies most impacted.  “This wasn’t collaboration—it was a box-checking exercise,” said Chino Mayor Eunice Ulloa. “IEUA mischaracterized the process as thorough, while withholding key documents and dismissing any agency or person who raised concerns. Even the rate study that underpins this decision was withheld until the legal deadline, leaving no time for cities or residents to evaluate its assumptions or implications.

From wetlands to rocket fuel, how CSULB is fighting climate change

California’s climate story is often told in extremes — droughts and floods, wildfires and coastal erosion, smoggy freeways and warming waters. But at Cal State Long Beach, a quieter kind of climate work is underway: in labs, along the coast and in classrooms where students engage with more than 150 sustainability-related courses. And it’s not just theoretical. Faculty — especially in the colleges of Natural Sciences and Mathematics and Engineering — are tackling climate change head on: advancing clean energy, building resilient infrastructure and protecting wildlife.

An ancient irrigation system may help farmers face climate change

“On a stormy spring day, Devon Peña stood atop a sagebrush-covered hill and looked down on Colorado’s San Luis Valley. Dark clouds had unleashed a deluge just a few hours earlier, but now they hovered over the mountains, veiling the summits above. Below, rows of long, narrow fields extended from Culebra Creek toward a man-made channel, the main artery of the valley’s centuries-old “acequia” irrigation system. This was the “People’s Ditch,” a waterway holding the oldest continuous water right in Colorado. The channel carried water from tributaries of the Rio Grande, high in the Sangre de Cristo mountains, down to the fields below. There, the flow was diverted into smaller ditches that irrigated fields of alfalfa, cabbage, and potatoes, the water seeping naturally through the earthen walls. In the San Luis Valley as a whole, 130 gravity-flow ditches irrigated 30,000 acres of farmland and 10,000 acres of wetlands. “This is an incredibly productive, resilient, and sustainable system,” said Peña, founder of The Acequia Institute, a nonprofit that supports environmental and food justice in southern Colorado. … ”  Read more from Civil Eats.

Advocates say the technology works, and now they need to figure out exactly how much.  For a practice that has launched millions of dollars in funding, countless snowflakes and a string of death threats, the technology itself is strikingly uncomplicated. … ”  Read more from KUNC.

With future funding of Colorado’s water projects uncertain, lawmakers begin to hunt for solutions

“With a critical source of funding for Colorado’s water projects facing an uncertain future, lawmakers want to task a group of experts with providing recommendations for solutions.  Severance taxes, which are imposed on nonrenewable energy extraction like oil drilling and coal mining, have long served as a key source of revenue for water-related initiatives. The funding stream, however, is also one of the state’s most volatile due to extreme swings in the energy market.  Over the past two decades, tax revenue has gone from skyrocketing one year to plummeting the next. The issue has compounded in recent years due to state budget writers siphoning some of the money to help balance the state’s spending plan. … ”  Read more from the Aspen Times.

Stripping federal protection for clean water harms just about everyone, especially already vulnerable communities

“Before Congress passed the Clean Water Act in 1972, U.S. factories and cities could pipe their pollution directly into waterways. Rivers, including the Potomac in Washington, smelled of raw sewage and contained toxic chemicals. Ohio’s Cuyahoga River was so contaminated, its oil slicks erupted in flames.  That unchecked pollution didn’t just harm the rivers and their ecosystems; it harmed the humans who relied on their water.  The Clean Water Act established a federal framework “to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters.”  As an attorney and law professor, I’ve spent my career upholding these protections and teaching students about their legal and historical significance. That’s why I’m deeply concerned about the federal government’s new efforts to roll back those safeguards and the impact they’ll have on human lives. … ”  Read more from The Conversation.

Facing shortages, cities tap sewers to bolster drinking water supply

“On a hot day, there’s nothing quite like a refreshing drink of water. But how would you feel if that water was sourced from the sewer?  As cities across the West brace for a drier future, they’re investing in advanced water purification technology. It flushes out the contaminants in wastewater so that the murky stuff that goes down your toilet can eventually come out ready to drink at your sink.  “There’s a lot of uncertainty here in terms of water resources, so we think that this is that next bucket of water that we need to tap into,” said Nazario Prieto, assistant director of Phoenix Water Services.  The city of 1.6 million people is building its first advanced water purification plant that could eventually process up to 15 million gallons of wastewater a day. … ”  Read more from WBUR.

From sewer to solution: Stanford engineers reinvent wastewater purification to unlock valuable resources

“Wastewater isn’t just waste – it’s packed with hidden value. Stanford researchers are developing cutting-edge resins – porous beads that together act like a coffee filter – not only to remove contaminants but also to recover valuable products, like ammonia for fertilizer. With global demand for drinkable water projected to exceed supply by 40% by 2030, the project has the potential to make water treatment cheaper, more efficient, and even profitable.  “Amidst efforts to reduce the emissions, energy, and cost of chemical manufacturing, selective resins can enable circular economies that convert pollutants into products by using wastewater as a feedstock,” said William Tarpeh, assistant professor of chemical engineering and one of the project’s principal investigators. “Wastewater treatment plants are increasingly being reconceptualized as water resource recovery facilities that achieve multiple co-benefits at once.” … ”  Read more from Stanford News.

AI cooling demands push data centers into deep water

With AI driving rapid growth in global data center infrastructure, the water required to cool those facilities is emerging as a significant financial, operational, and reputational risk.  According to a recent Moody’s report, “water stress” is escalating in key data center markets.  The consulting firm identifies water scarcity as a growing credit risk for data center operators, particularly hyperscale providers supporting AI workloads that require denser compute power and higher thermal loads.  “As cloud computing and hyperscalers build or lease new data centers to meet escalating computing demand, their water consumption may strain resources in some markets,” the report cautions. … ”  Read more from Data Center Knowledge.

EPA orders staff to begin canceling research grants

“Following in the footsteps of other federal science agencies under President Donald Trump’s administration, the Environmental Protection Agency (EPA) last week ordered its staff to start canceling grants already awarded to universities and research institutes, according to an agency source and an email seen by Science. Although EPA is not a large funder of R&D compared with other federal agencies, it does provide $35 million to $40 million each year to researchers studying the impacts of pollution and ways to reduce them.  The internal email, sent between senior agency administrators, gave no reason for scrapping the grants, but the Trump administration has also been downsizing EPA activities in other ways. … ”  Read more from Science.

EPA administrator defends sweeping grant terminations amid legal blowback

“EPA Administrator Lee Zeldin on Monday defended his agency’s abrupt cancellation of billions of dollars in federal clean energy and environmental justice grants, insisting the EPA retains discretion to terminate awards despite a federal court ruling that sharply questioned the legal basis for the move.  Facing mounting scrutiny, Zeldin held a press conference ahead of his Earth Day trip to the U.S.-Mexico border to address sewage contamination. He said the terminations were a responsible effort to prevent “lighting billions of dollars on fire” and repeated his claims of program mismanagement and political favoritism, which have been challenged in court.  The money at issue is the $27 billion Greenhouse Gas Reduction Fund (GGRF) initiative created under the Inflation Reduction Act to accelerate clean energy lending and community investment. … ”  Read more from Inside Climate News.
