Gov. Jared Polis and Dan Gibbs, Executive Director,
Colorado Department of Natural Resources announced Jason
Ullmann as the next Colorado State Engineer and Director of the
Division of Water Resources (DWR). … Jason brings over 20
years of experience in water resources engineering, 14 years of
which have been at DWR, most recently as the Deputy State
Engineer. Before his time with DWR, he gained valuable
experience in water resources management as a City Engineer for
the City of Montrose and as a consulting engineer for various
ditch and reservoir companies throughout Colorado.
Karrigan Börk, UC Davis professor of law and Associate Director
at the Center for Watershed Sciences, has been awarded the
prestigious $10,000 Morrison Prize for his paper on water
rights. The Sandra Day O’Connor College of Law at Arizona State
University recognizes Börk’s paper as “the most impactful
sustainability-related legal academic paper published in North
America” for 2023. Börk’s winning paper, “Water Exaction
Rights,” published in the Harvard Environmental Law Review,
proposes a solution to address current and future water crises
in the US: an exactions framework.
Does the public sector need the private sector’s help to
address the freshwater crisis? That’s the controversial thesis
of Stanford law and environmental social sciences professor
Barton “Buzz” Thompson’s provocatively titled new book: Liquid
Asset: How Business and Government Can Partner to Solve the
Freshwater Crisis. (Buzz is also a member of the PPIC Water
Policy Center’s research network.) We sat down with him to hear
more. … The private sector is already involved in water in
many ways, some more controversial than others. … We
think of the Sustainable Groundwater Management Act (SGMA) as a
public program, and it is. The legislature passed the law, and
public agencies are implementing it. But if you look carefully,
you’ll see private handprints all over SGMA’s success.
California farmers could save massive amounts of water if they
planted less thirsty — but also less lucrative — crops such as
grains and hay instead of almonds and alfalfa, according to new
research by scientists who used remote sensing and artificial
intelligence. Such a seismic shift in the nation’s most
productive agricultural state could cut consumption by roughly
93%, researchers with UC Santa Barbara and the NASA Jet
Propulsion Laboratory reported Monday. But Anna Boser, the
study’s lead author, acknowledged that replacing all of
California’s water-intensive crops with the least-intensive
ones is an unrealistic economic scenario. … In a
less-extreme scenario, Boser and her colleagues reported that
fallowing 5% of fields with the most water-intensive crops
could cut water consumption by more than 9%, according to
the study, published in the journal Nature Communications.
The first publication by the newly renamed California Nature
Art Museum in Solvang (formerly the Wildling Museum of Art &
Nature) builds quite nicely on the institution’s vision to “be
recognized as an exceptional and innovative leader in inspiring
our communities and visitors to value wilderness and other
natural areas through the lenses of a diversity of artists.”
Featuring text and stunning photography by George Rose,
California’s Changing Landscape: The Way of Water is an
expansive large-format documentation of California’s vast
terrain, complicated weather, and extensive biodiversity —
particularly as they relate to water and, as naturally follows,
climate change.
Efficiently managing agricultural irrigation is vital for food
security today and into the future under climate change. Yet,
evaluating agriculture’s hydrological impacts and strategies to
reduce them remains challenging due to a lack of field-scale
data on crop water consumption. Here, we develop a method to
fill this gap using remote sensing and machine learning, and
leverage it to assess water saving strategies in California’s
Central Valley. We find that switching to lower water intensity
crops can reduce consumption by up to 93%, but this requires
adopting uncommon crop types. … These results reveal diverse
approaches for achieving sustainable water use, emphasizing the
potential of sub-field scale crop water consumption maps to
guide water management in California and beyond.
Microplastics are tiny, nearly indestructible fragments shed
from everyday plastic products. As we learn more about
microplastics, the news keeps getting worse. Already
well-documented in our oceans and soil, we’re now discovering
them in the unlikeliest of places: our arteries, lungs and even
placentas. Microplastics can take anywhere from 100 to 1,000
years to break down and, in the meantime, our planet and bodies
are becoming more polluted with these materials every day.
Finding viable alternatives to traditional petroleum-based
plastics and microplastics has never been more important. New
research from scientists at the University of California San
Diego and materials-science company Algenesis shows that their
plant-based polymers biodegrade — even at the microplastic
level — in under seven months. The paper, whose authors are all
UC San Diego professors, alumni or former research scientists,
appears in Nature Scientific Reports.
With only three months left on her contract, the longtime
attorney for the powerful Kern County Water Agency was ousted
Monday, March 18, during a special meeting. Six of the agency’s
seven directors voted in favor of terminating General Counsel
Amelia Minaberrigarai’s contract after a short closed session.
Director Laura Cattani was absent. The contract was terminated
as of March 23. It is set to expire June 30. … The
agency did not respond to questions about whether the
termination was for cause. Nor to questions about
Minaberrigarai’s replacement. It is also unclear why her
contract was terminated with only three months before it
expired. If she was fired without cause, the contract
requires she receive a lump sum equal to her base pay,
plus vacation that would have accrued for the remainder of the
contract’s term.
NASA and the German Space Agency at DLR (German Aerospace
Center) have agreed to jointly build, launch, and operate a
pair of spacecraft that will yield insights into how Earth’s
water, ice, and land masses are shifting by measuring monthly
changes in the planet’s gravity field. Tracking large-scale
mass changes – showing when and where water moves within and
between the atmosphere, oceans, underground aquifers, and ice
sheets – provides a view into Earth’s water cycle, including
changes in response to drivers like climate change.
Set against the context of unprecedented demand for water
supply solutions, Brownstein and WestWater Research brought
together water industry and finance leaders for the second
annual Sustainable Water Investment Summit. The World Resources
Institute’s latest data helps articulate the scale of the
demand for water supply reliability, sustainability and
innovation: by 2050, an additional billion people will be
living in arid areas and regions with high water stress, and by
2050, around 46% of global GDP is expected to come
from areas facing high-water risk (up from 10% currently).
Given these realities, it’s unsurprising that diverse interests
are now converging to meet the challenges of ensuring a
resilient and accessible water future. Polls find that 63% of
global companies now undertake water-related risk assessments,
and 1,100 CEOs have annual performance reviews tied to results
around water goals.
What if the looming calamities of climate change, plastic
pollution, the energy crisis and our whole environmental
doom-scroll are symptoms of just one malady and it’s something
we actually can fix? That’s right, the planet is fighting a
single archvillain: Waste. Americans live in the most wasteful
civilization in history. … Waste is so deeply embedded in our
economy, products and daily lives that it’s hard to see
clearly, or to see at all. … How is it “normal”
that 40% of what our industrial farm and food system
produces ends up as garbage? … The average American
throws out three times more trash today than in 1960. Pin much
of that garbage growth on plastic waste, so pervasive now that
tiny bits of it are in food, water, beer and even human hearts,
lungs and newborn babies’ poop. -Written by Edward Humes, a Pulitzer Prize-winning
journalist. His latest book, “Total Garbage: How We Can Fix Our
Waste and Heal Our World,” will be published in April.
The Gila River Indian Community says it does not support a
three-state proposal for managing the Colorado River’s
shrinking supply in the future. The community, which is located
in Arizona, is instead working with the federal government to
develop its own proposal for water sharing. The tribe is among
the most prominent of the 30 federally-recognized tribes that
use the Colorado River. In recent years, it has signed
high-profile deals with the federal government to receive big
payments in exchange for water conservation. Those deals were
celebrated by Arizona’s top water officials. But now, it is
diverging from states in the river’s Lower Basin — Arizona,
California and Nevada. Stephen Roe Lewis, The Gila River Indian
Community’s Governor, announced his tribe’s disapproval of the
Lower Basin proposal at a water conference in Tucson, Ariz.,
while speaking to a room of policy experts and water
scientists.
The European Commission said on Wednesday it was taking Greece
to the EU’s top court for failing to revise its flood risk
management plans, a key tool for EU countries to prepare
themselves against floods. The action comes five months
after the worst rains in Greece flooded its fertile
Thessaly plain, devastating crops and livestock and raising
questions about the Mediterranean country’s ability to deal
with an increasingly erratic climate. Under EU rules,
countries need to update once in six years their flood
management plans, a set of measures aimed to help them mitigate
the risks of floods on human lives, the environment and
economic activities. Greece was formally notified by the
Commission last year that it should finalise its management
plans but the country has so far failed to review, adopt or
report its flood risk management plans, the Commission said in
a statement.
A new study by Cal State Fullerton researchers shows evidence
of two epic floods that occurred within the past 500 years in
Southern California during the Little Ice Age. Their
research is the first-ever, land-based, flood-event evidence
from 1450 to 1850 — a documented period of above-average
wetness in Southern California, said Matthew E. Kirby,
professor of geological sciences. According to scientists,
floods — not earthquakes — represent California’s single most
significant socioeconomic natural hazard risk.
… Climate models predict that the frequency of
large flood-producing precipitation events will increase in the
21st century due to climate change.
California citrus farmers are finding ways to adapt to the
changing landscape, as the challenges of this production year
come to light. Amid the harvest of California navels,
mandarins, and other specialty varieties, two industry leaders
share their perspectives on the prospects of the industry.
… Jim Phillips, President and CEO of Sunkist, expressed
similar concerns regarding production but also emphasized the
current state of affairs regarding the Sustainable Groundwater
Management Act (SGMA). California citrus farmers need the
support of the legislature regarding water access, as the issue
is outpacing almost every other concern for growers, said
Phillips. Both Bates and Phillips noted that the
substantial amount of rainfall and snowpack over the past two
winters are supporting growers in the fight for water access.
A powerful winter storm buried the Sierra last weekend, with
wet weather continuing for days in the Bay Area and Central
Coast. Thunderstorms Wednesday drenched Salinas, dropping
an entire inch in just 25 minutes. After historic weather last
year, intense California storms have persisted this winter,
with strong downpours causing widespread flooding in San Diego
and damaging landslides in places like Los Angeles. Many
ingredients contribute to extreme storm activity, but
scientists agree that climate change is already amping up
winter rains — and may bring even wilder weather in the
future.
California has set ambitious climate goals, including phasing
out the use of fossil fuels and becoming carbon neutral by
2045. Our guest today is here to talk about the role nature can
play in meeting those goals. Laurie Wayburn is the co-founder
and president of the Pacific Forest Trust and the chair of the
California Natural and Working Lands Expert Advisory Committee.
She was also the lead author of a recent report suggesting the
state should invest “as much in nature-based climate solutions
as it has in clean energy and transportation.” With proper
forest management, California could capture 400 million tons of
carbon each year, lower wildfire risk and vastly improve flood
protection in the state.
This month, several wildlife conservation groups petitioned the
California Fish and Game Commission to list these owls as
endangered or threatened under the California Endangered
Species Act. … [Chair of the environmental studies department
at San Jose State University Lynne] Trulio’s speciality is
urban species, and she’s contributed to the research that
underpins Santa Clara County’s habitat conservation plan on
burrowing owls. But before that she was also the lead scientist
for the South Bay Salt Pond Restoration Project, one of
the largest tidal wetland restoration projects on the West
Coast. “One of the things that drove the effort was the
fact that there were endangered species” in wetlands, said
Trulio. She said it took years to change the perception of the
wetlands as a dumping ground and to get a ballot measure to
fund its preservation.
Cannon Michael has been re-elected as the chairman of the San
Luis & Delta-Mendota Water Authority. The San Luis &
Delta-Mendota Water Authority announced Michael’s re-election
on Monday. The big picture: Michael is the president
of family-owned Los Banos farming operation Bowles Farming
Company. He also serves as the chair of the Henry Miller
Reclamation District, as a board member of the Water Education
Foundation and as an advisory board member of the Public Policy
Institute of California.
A pair of new state bills are looking to crack down on some of
the polluters fueling the cross-border sewage crisis that has
hobbled access to San Diego County’s southernmost beaches for
decades. Senate Bill 1178 and Senate Bill 1208, introduced on
Monday by State Sen. Steve Padilla, add regulations to water
discharges for large corporations, as well as prevent water
authorities from issuing additional permits for waste releases
into areas in the Tijuana River system.
