November is time to enjoy fresh #pomegranates, says #UCCE advisor Katie Johnson. "Pomegranates are at their peak during the fall. A ripe pomegranate should feel firm and heavy for its size, reflecting an interior that is well-filled with juicy seeds." http://ow.ly/RipX50C9rXt

In California, most ghost towns were created when a local industry collapsed. Now, climate change is more often to blame when booming communities whither and die, reported Daniel Cusick in E&E News.

Cusick wrote about five towns around the nation that have died or are dying from climate-related disasters. Historic Shasta and Helena, Calif., featured in one of the vignettes, fell to wildfire.

Cattle, forage and ranching infrastructure losses from the SCU Lightning Complex fire, which burned 396,624 acres of primarily rangeland in Alameda, Santa Clara, San Joaquin, Merced, Contra Costa and Stanislaus counties, reached $68.2 million, according to an initial assessment by UC Cooperative Extension livestock and natural resource advisors Theresa Becchetti and Sheila Barry.

Outsized wildfires, rising sea levels and disappearing glaciers are dramatic signs of climate change, but not the only ones.

New UC ANR research provides forewarning of a change that will be economically and environmentally costly to California – a fifth generation of navel orangeworm, the most destructive pest of almonds, walnuts and pistachios.

“Elderberries have this great potential as a ‘win-win’ crop. Farmers harvesting and selling elderberries from their hedgerows can receive a direct income from a farm practice that benefits the local ecosystem,” says Sonja Brodt, deputy director of the UC Sustainable Agriculture Research & Education Program.

The Case for Reviving the Civilian Conservation Corps

Lenya N. Quinn-Davidson, area fire adviser for UC Cooperative Extension - Humboldt/Del Norte Counties, cofounded the Humboldt County Prescribed Burn Association. The group’s experts craft prescribed burn plans for owners of private land, and local volunteers do the actual work.

“It really is a social movement around prescribed fire,” Quinn-Davidson says. Since their founding, a dozen other similar groups have formed across California. “It's a great grassroots, local model of people helping each other out, and getting the work done virtually for free,” Quinn-Davidson tells WIRED.

California now produces more than 360 commodities organically, worth over $3 billion, according to a new UC report. San Diego County had the most organic growers in 2016, but Kern County’s organic farmers earned the most in total organic sales.

“The average gross income of organic farms increased 14-fold from 1994 to 2016, reaching $1 million in 2016,” said Joji Muramoto, UC Cooperative Extension organic production specialist at UC Santa Cruz Center for Agroecology & Sustainable Food Systems and coauthor of the report. “However, 77% of growers received less than $500,000 per year and 22% of growers who made $500,000 or more per year received 94% of the total gross sales."

Improved soil health, increased profitability & reduced #wildfire fuel are among benefits of livestock grazing on the landscape.

Nick Jorgensen, CEO of Jorgensen Land and Cattle in Ideal, SD, said that grazing allows his operation to increase soil organic matter by up to 0.75% per year and cut fertilizer costs by $50 per acre with no yield loss.

South Dakota Soil Health Coalition and UCCE Sonoma are connecting landowners with livestock owners for free. In California, check out MatchGraze.com. In South Dakota, it's sdgrazingexchange.com.

Society gains $10 in benefits, on average, per $1 invested in international agricultural research and development, according to a new report by the Supporters of Agricultural Research (SoAR) Foundation.

“This report shows that international agricultural R&D, of the type that drove the Green Revolution, continues to generate a fantastic rate of return and that we have not been investing nearly enough in the types of agricultural R&D undertaken by the CGIAR,” said Julian M. Alston, distinguished professor of agricultural resources economics at College of Agricultural and Environmental Sciences, UC Davis and coauthor of “The Payoff to Investing in CGIAR Research.” https://bit.ly/2IzL5wF

Changes like cafeteria redesign, education for teachers on school lunches and increased vending machines and food carts boosted positive perceptions about school lunches, UC researchers found.

"We found that these positive perceptions toward school lunch also increased reports of consumption of fruits and vegetables among students very modestly," said Lorrene Ritchie, director of UC ANR's Nutrition Policy Institute.

"The most successful reforestation happens if planning begins as soon as the flames die down,” says Dr. Bill Stewart, co-director of Berkeley Forests. Today, the organization released a new book, "Reforestation Practices for Conifers in California," for free download.

The manual presents a planning process, with a detailed explanation of the options at each step. These basic steps are the same for a small landowner, large landowner, or an agency.
