More than one-third of the world’s population lives in water-scarce regions, and by mid-century, half of the projected 9.8 billion people on Earth “could be at risk due to water stress,” said a report out today from the Chicago Council on Global Affairs.
With one month left in what are California’s three wettest months of the year, the snowpack in the Sierra Nevada is at 27 percent of average for the start of February, said the state Department of Water Resources.
State officials are expected to fight the Trump administration’s proposal to “maximize water deliveries” through the Central Valley Project to Southern California, including farmers in the Westlands Water District, the largest agricultural water district in the nation, says the Sacramento Bee.
For hundreds of years, a network of earthen canals that ribbon through New Mexico have been central to a thriving small-farm scene and a communal way of life. But those canals, called acequias, and the way of life they support, are being pushed to the brink by a changing climate, a development boom, and the imperatives of the modern economy, says Alexis Adams in FERN's latest story, published with The Weather Channel.

Midwestern farmers, seeking to expand their crop lands, are destroying millions of trees that helped protect the region's soil after the catastrophic Dust Bowl of the 1930s. The removal of these trees is expected to worsen the impact of a drought that could come as climate warms the region, says Carson Vaughn in FERN’s story with Weather.com.
A decade or more ago, farmers in the San Luis Valley in southern Colorado began to run out of irrigation water. The solution, after years of court cases and finger-pointing, was an agreement to raise the price of water, says the NPR blog The Salt.
Changes in soil moisture and increased temperatures could make some areas newly suitable for rainfed, non-irrigated agriculture, but others could lose viability, says a study published in the journal Nature by the U.S. Geological Survey.
The Ogallala aquifer shrank twice as fast in the last six years as it did in the previous 60, largely from over-pumping on farms, reports The Associated Press. The aquifer — a key source of irrigation water for farms in eight states — lost 10.7 million acre-feet of storage between 2013 and 2015, drying up streambeds, undermining fish species and threatening the farmers who rely on Ogallala for their crops.
The board of the largely agricutlural Westlands Water District voted 7-1 against taking part in Gov. Jerry Brown's twin-tunnel project "to remake the fragile estuary that serves as the hub of California's water delivery network," reports the Sacramento Bee. The decision, by the first water agency to vote on the project, is "a potentially fatal blow" to the $17-billion project.
An audit by the Interior Department's inspector general says the government improperly spent $84 million to help plan the mammoth twin-tunnel project to ship water to Southern California from northern parts of the state, reported The Associated Press. The audit said the expenditures meant the Bureau of Reclamation paid for one-third of the cost of project planning through 2016, when California water districts were supposed to bear the costs.
