Overview

Agricultural Conservation

As the single largest water-consuming industry, agriculture has become a focal point for efforts to promote water conservation. The drive for water use efficiency has become institutionalized in agriculture through numerous federal, state and local programs. Since the 1980s, some water districts serving agricultural areas have developed extensive water conservation programs to help their customers (From Aquapedia).

Facing an uncertain water future

The future availability of irrigation water for California growers has never been less certain. To help growers survive a future of “water uncertainty,” the non-profit Soil Health Academy today announced an on-farm school at the Burroughs Family almond orchard April 30-May 2 in Denair, California, that will offer agricultural producers principles and tools to grow profits and resiliency with much less water. The school, sponsored by Simple Mills, will feature instruction, demonstrations and insights from world-renowned soil health pioneers Gabe Brown, Allen Williams, Ph.D., along with Chuck Schembre and other orchard, vineyard and vegetable production experts.

Better data key to informed water policy decisions

To adapt to climate extremes and become more water resilient in California, modernizing the state’s water data—including the way it is collected, stored, shared and used—may lead to more informed decisions. Improving data practices to best manage California’s water resources helped drive discussions last week as state and local water managers, farmers, environmentalists and others gathered in Sacramento for the 62nd annual California Irrigation Institute Conference. … With a theme of “Fluid Futures: Adapting to Extremes,” the Feb. 26-27 event focused on leveraging information and data technology to help with water-management decisions. Erin Urquhart, water resources program manager for the National Aeronautics and Space Administration, offered insights on the benefits of Earth-observing missions that gather water data from space.

Report: Unlicensed cannabis grows use more water than licensed grows in California

The University of California, Berkeley (UCB) recently published a scientific brief in February regarding illegal water use for cannabis plants. Entitled “Water Use: Cannabis in Context,” the brief was conducted by individuals at the Berkeley Cannabis Research Center, which is part of the College of Environmental Science Policy & Management. The Cannabis Research Center has been reviewing cannabis water use since 2017, and the most recent brief is split into four sections posed with a question. First, “How much water does cannabis use relative to stream flow?” explains that cannabis water use in regions along the Northern California coast and semi-inland areas (primarily Humboldt and Mendocino County) represents a “small fraction” of surface water supplies year-round, and especially during the months of July, August, and September.

OpenET study helps water managers & farmers put NASA data to work

As the world looks for sustainable solutions, a system tapping into NASA satellite data for water management has passed a critical test. Called OpenET, the system uses an ensemble of six satellite-driven models that harness publicly available data from the Landsat program to calculate evapotranspiration (ET)—the movement of water vapor from soil and plant leaves into the atmosphere. OpenET does this on a field-level scale that is greatly improving the way farmers, ranchers, and water resource managers steward one of Earth’s most precious resources. Researchers have now conducted a large-scale analysis of how well OpenET is tracking evapotranspiration over crops and natural landscapes. The team compared OpenET data with measurements from 152 sites with ground-based instruments across the United States. In agricultural areas, OpenET calculated evapotranspiration with high accuracy, especially for annual crops such as wheat, corn, soy, and rice.

California Water Agencies Hoped A Deluge Would Recharge Their Aquifers. But When It Came, Some Couldn’t Use It
WESTERN WATER IN-DEPTH: January storms jump-started recharge projects in badly overdrafted San Joaquin Valley, but hurdles with state permits and infrastructure hindered some efforts

An intentionally flooded almond orchard in Tulare CountyIt was exactly the sort of deluge California groundwater agencies have been counting on to replenish their overworked aquifers.

The start of 2023 brought a parade of torrential Pacific storms to bone dry California. Snow piled up across the Sierra Nevada at a near-record pace while runoff from the foothills gushed into the Central Valley, swelling rivers over their banks and filling seasonal creeks for the first time in half a decade.    

Suddenly, water managers and farmers toiling in one of the state’s most groundwater-depleted regions had an opportunity to capture stormwater and bank it underground. Enterprising agencies diverted water from rushing rivers and creeks into manmade recharge basins or intentionally flooded orchards and farmland. Others snagged temporary permits from the state to pull from streams they ordinarily couldn’t touch.

In the Heart of the San Joaquin Valley, Two Groundwater Sustainability Agencies Try to Find Their Balance
WESTERN WATER SPECIAL REPORT: Agencies in Fresno, Tulare counties pursue different approaches to address overdraft and meet requirements of California’s groundwater law

Flooding permanent crops seasonally, such as this vineyard at Terranova Ranch in Fresno County, is one innovative strategy to recharge aquifers.Across a sprawling corner of southern Tulare County snug against the Sierra Nevada, a bounty of navel oranges, grapes, pistachios, hay and other crops sprout from the loam and clay of the San Joaquin Valley. Groundwater helps keep these orchards, vineyards and fields vibrant and supports a multibillion-dollar agricultural economy across the valley. But that bounty has come at a price. Overpumping of groundwater has depleted aquifers, dried up household wells and degraded ecosystems.

As Deadline Looms for California’s Badly Overdrafted Groundwater Basins, Kern County Seeks a Balance to Keep Farms Thriving
WESTERN WATER SPOTLIGHT: Sustainability plans required by the state’s groundwater law could cap Kern County pumping, alter what's grown and how land is used

Water sprinklers irrigate a field in the southern region of the San Joaquin Valley in Kern County.Groundwater helped make Kern County the king of California agricultural production, with a $7 billion annual array of crops that help feed the nation. That success has come at a price, however. Decades of unchecked groundwater pumping in the county and elsewhere across the state have left some aquifers severely depleted. Now, the county’s water managers have less than a year left to devise a plan that manages and protects groundwater for the long term, yet ensures that Kern County’s economy can continue to thrive, even with less water.

Could the Arizona Desert Offer California and the West a Guide to Solving Groundwater Problems?
WESTERN WATER SPOTLIGHT: Environmental Defense Fund report highlights strategies from Phoenix and elsewhere for managing demands on groundwater

Skyline of Phoenix, ArizonaAs California embarks on its unprecedented mission to harness groundwater pumping, the Arizona desert may provide one guide that local managers can look to as they seek to arrest years of overdraft.

Groundwater is stressed by a demand that often outpaces natural and artificial recharge. In California, awareness of groundwater’s importance resulted in the landmark Sustainable Groundwater Management Act in 2014 that aims to have the most severely depleted basins in a state of balance in about 20 years.

Water Use Efficiency

The message is oft-repeated that water must be conserved and used as wisely as possible.

The California Water Code calls water use efficiency “the efficient management of water resources for beneficial uses, preventing waste, or accomplishing additional benefits with the same amount of water.”
