You are now in California and the U.S. category.

On February 20, California’s State Water Resources Control Board postponed a decision on the adoption of new statewide regulations meant to curb wasteful water practices. The regulations would make permanent some rules California enacted temporarily during the recent drought, which ended last year. After several public comment periods this winter, water board staff tweaked the regulations to address concerns and recommendations from water users and other groups, but the postponement came after a large number of water agencies claimed the regulations are a violation of water rights.

A new University of California report forecasts kick-to-the-gut climate-change realities for California farmers, especially those who grow permanent crops in the Central Valley. In a nutshell, the report anticipates big trouble ahead for crops such as almonds, peaches, table grapes, corn and rice. Scorching summer heat and longer periods of sustained drought will reduce yields. Higher temperatures also will provide a perfect incubator for insects and diseases. Some longtime Valley staples won’t be grown here at all. Ag is nimble in adapting to challenges.

If we had known a year ago that this winter would be so dry, would we have conserved water more aggressively last summer? Would ski resorts have installed more snowmaking equipment? Would farmers buy different seeds to plant this spring? These are among the tantalizing questions raised by a team of government and university scientists, who believe they have developed a tool to predict mountain snowpack in the West up to eight months in advance – long before the first winter snowflake has fallen.

After months of relatively dry weather in California, this winter’s biggest storm to date is set to deliver rain at lower elevations and feet of snow in the Sierra Nevada mountains. That’s good news for the precipitation-starved state, but will this storm be enough to mitigate the growing number of areas facing severe drought? The National Weather Service reports that the storm will begin late tonight and impact the state through Saturday.

California currently provides two-thirds of the country’s fruits and nuts, but according to a new study published Tuesday, by the end of the century California’s climate will no longer be able to support the state’s major crops, including orchards. The report, published in “Agronomy,” warns that the increased rate and scale of climate change is “beyond the realm of experience” for the agricultural community, and unless farmers take urgent measures, the consequences could threaten national food security.
