UC has a great web site designed to inform the public and other UC scientists about the research they are doing related to climate change in California. It can be found at http://groups.ucanr.org/CAClimateChangeExt.
The site was designed by Monique Myers, UCCE coastal community development advisor for Los Angeles and Ventura counties, and Susan Schlosser, UCCE marine advisor for Humboldt and Mendocino counties. “The objective is to raise awareness and get good science-based information out to the public. By expanding the site to include pages that highlight researchers doing California climate change research at UC, I think the info will be useful to other UC researchers,” Myers said.
The site is extremely interesting and features researchers covering many fields including: plant science, biometeorology, hydrology, sustainable energy, oceanography, environmental policy, climatology, geochemistry and much more. Information can be viewed in text format, or by watching video interviews with the researchers. The interviews are segmented into “Quick Topics” which are about 2-3 minutes in length. Not only do the interviews extend information, but the researcher’s positive commitment and passion on the issues add a powerful and personal touch. Examples of Quick Topics include: Climate Change Impacts on Water Supply, The West is Particularly Vulnerable, Emissions Trading, Transportation Solutions, and Carbon Footprinting.
Further information about the scientists and their research projects and publications is easy to find. A section of further links provides direction for additional learning.

Ventura County UCCE Staff Research Associate Maren Mochizuki shares current research which hopes to provide an organic method to kill plant pathogens and weed seeds in production agriculture.
Synthetic chemicals to fumigate soil have been used in some production agricultural systems, to kill plant pathogens and weed seed before planting crops. Here in Ventura County, this is a common practice for strawberry production. Joji Muramoto, Associate Researcher at UC Santa Cruz and Oleg Daugovish, Ventura County UCCE Farm Advisor and Maren Mochizuki, Ventura County UCCE Staff Research Associate are investigating an organic method to treat soil before planting by creating anaerobic, or oxygen-free, conditions. Most organisms, including plant pathogens, cannot survive without oxygen.
We incorporated rice bran from the Central Valley into the soil as a carbon source to trigger microbial activity. To test the applicability within a strawberry production system, we created planting beds topped with plastic mulch. The beds needed to be well-sealed to ensure no air leaks that could add oxygen. Using drip irrigation, we added sufficient water to the beds to fill all soil pores, further pushing out any air/oxygen. Each day we monitor the soil environment with sensors measuring soil water content, temperature, and the level of anaerobic conditions and add more water as needed. At the end of three weeks, we will evaluate the survival of a significant plant pathogen, Verticillium dahliae.

Below you will find a summary of what we did last month. By no means does this summary capture all that we accomplished or began, but it gives a nice glimpse of what we do.
1. Research Activities
This is a sampling of the research activity conducted in June.
- Established an experiment testing an herbicide for management of yellow nutsedge, a major weed in production agriculture costing Ventura County growers thousands of dollars annually to control. For more information on nutsedge and its impact, please read previous blog posts.
- Established an experiment testing an organic method of soil disinfestations by creating anaerobic conditions in strawberry beds and monitoring effects on plant pathogen Verticillium dahliae. This research makes direct contributions by addressing the issue of seeking alternatives to fumigants such as methyl bromide.
- Finished four field trials that evaluate management options for four pests detrimental to the strawberry industry. Management strategies included physical, thermal and chemical control measures.
- Initiated a project with CA Dept. of Food and Agriculture and local strawberry growers to introduce a biocontrol agent for Lygus bug, the #1 insect pest for strawberries and significant for other row crops.
- We are continuing research on minimizing irrigation needs for strawberries, which addresses both economic and environmental issues.
2. Educational Activities
This is a sampling of the educational activities conducted in June.
A. Grower/Clientele Education
- Jim Downer presented sessions at a regional meeting on nutrition of palms and diseases of shade trees. 100 in attendance.
- Ben Faber participated in a program at UC Riverside on Asian Citrus Psyllid (ACP), which poses a significant threat to the citrus industry. It was clear that fruit from affected areas coming into Ventura County packing houses could be a host for the psyllid. Ben spoke to Henry Gonzales about this and as a result the import of lemons from Imperial County (quarantine area) to Ventura for repacking has been restricted to reduce the likelihood of introducing the pest here. Both Faber and Rose Hayden-Smith participated in a meeting that brought packers together with the Ag Commissioner, where they hammered out a solution/agreement.
- Ben Faber delivered two grower workshops, one on avocado irrigation and the other on techniques to reduce surface water contamination.
- Rose Hayden-Smith presented her research on gardening and community development at a City of Minneapolis/IATP event attended by more than 100 people. She also presented a two-hour workshop on Victory Gardens, past and present, to a sold-out audience in Minneapolis. She offered a talk on gardening trends and public policy in Oxnard to an audience of 75. Earlier in the month, she facilitated an Urban Agriculture Symposium for 175 people in Chicago, which generated public policy recommendations for the USDA.
- Monique Myers presented the Ventura County RESTOR Project at the National Marine Educators conference in Monterey.
- Monique Myers organized a focus group for Ventura City/County Planners and city storm water experts addressing low impact development and emergency safety issues.
- 4-H staff trained staff at Pt. Mugu and Port Hueneme Naval Bases in the basics of 4-H program management. Also trained new 4-H club leaders.
B. Youth Education
- Monique Myers directed/facilitated the last of 8 RESTOR teacher/student field trips to Ormond Beach (~70 students per trip). RESTOR is a grant-funded wetlands/ecological restoration program linking teachers and youth with science education and community service opportunities.
- Monique Myers led a RESTOR Project field trip with 28 student essay contest winners and their teachers on the NOAA research vessel Shearwater.
- 4-H held a Science, Engineering and Technology Day at the military base.
- 4-H held events at both military bases kicking off the new 4-H programs there.
- UCCE staff. Launched a UCCE/Farm Advisor blog http://ucanr.org/blogs/venturacountyucce/
- UCCE staff. Produced a new UCCE/Farm Advisor educational brochure.
- Daugovish, Oleg and Maren Mochizuki submitted a paper to HortTechnology detailing the potential for carbon dioxide to be taken up by raspberry plants to boost productivity instead of being released to the atmosphere as a greenhouse gas. We hope this method will gain attention as one of the ways to tackle a global issue on a local scale.

See below for great news recently sent to the Ventura County UCCE office! For anyone who is interested we have copies of California Agriculture going back to 1950 in our library. Feel free to come by and take a look. To avoid disappointment, please call first to make sure the library is not being used for a meeting.
Sixty-three years of California Agriculture journal now online
This week, California Agriculture capped off a two-year effort with a keystroke, posting the full text of 63 years -- close to 6,000 articles -- to the World Wide Web. This rich store of peer-reviewed science dating back to 1946 is now freely accessible and searchable at the journal's redesigned Web site: http://californiaagriculture.ucanr.org/.
The previous California Agriculture Web site included articles back to 2000. Until now, however, most of the journal's long history of research has been in the shadows, accessible only as bound volumes in the stacks of a few UC libraries and others scattered around the world.
"This highly valuable research is now widely available online for the benefit of authors, readers and scientists worldwide," said Janet White, executive editor of California Agriculture journal. "Our old, well-worn hard copies have been transformed into high-quality, reusable XML-based content and full-text PDFs, with the highest levels of data integrity and readability."
Published by the University of California, California Agriculture began as a four-page broadsheet in December 1946. Today both print and Web versions are known for presenting new, peer-reviewed research in a meaningful context with technical terms defined -- making it accessible to a diverse audience of people who can use it, taking the final step in the research and delivery process.
California Agriculture is one of the oldest, continuously published, land-grant university research publications in the country, with one of the largest circulations among journals of its kind. Print subscribers include 17,000 growers, faculty members, environmental and health professionals, government researchers, public officials and others.
The California Agriculture archive includes landmark research that knits together our understanding of food and fiber production, forestry, fisheries, human health and nutrition, and how those endeavors have interacted with the natural environment and its ecosystems at every scale.
Aptara of Falls Church, Va., was hired to process over 550 back-dated journal issues, using the University's custom editorial specifications, converting them into XML files with cross-referencing for immediate posting online. The Web site redevelopment team included Janet White, Andrea Laue, Michael Talman, Davis Krauter, Karl Krist, Dave Krause and Janet Byron.
California Agriculture is still fine-tuning the Web site, and welcomes comments and feedback. Please take the online survey on the home page, or write to us at email@example.com .
