People who are interested in using drones for real-world mapping are invited to attend a three-day intensive drone workshop in the Monterey Bay Area. The third annual DroneCamp will be offered June 18-20 by UC Agriculture and Natural Resources' Informatics and GIS Program. No experience with drone technology is needed to participate.
Drone mapping involves taking high-resolution photos with drones and stitching them together with software to make extremely accurate, orthorectified maps. More difficult than videography, it is widely used in agriculture, construction, archeology, surveying, facilities management and other fields. DroneCamp will cover all the topics someone needs to make maps with drones, including:
- Technology - the different types of drone and sensor hardware, costs and applications
- Drone science - principles of photogrammetry and remote sensing
- Safety and regulations - learn to fly safely and legally, including tips on getting your FAA Part 107 Remote Pilot Certificate
- Mission planning - flight planning tools and principles for specific mission objectives
- Flight operations - hands-on practice with both manual and programmed flights
- Data processing - processing drone data into orthomosaics and 3D digital surface models; assessing quality control
- Data analysis - techniques for analyzing drone data in GIS and remote sensing software
- Visualization - create 3D models of your data
- Latest trends - hear about new and upcoming developments in drone technology, data processing, and regulations
On the first day, DroneCamp instructors will discuss drone platforms, sensor technologies and regulations. On the following two days, participants will receive hands-on instruction on flying safely, using automated flight software, emergency procedures, managing data, and turning images into maps using Pix4D mapper and ArcGIS Pro.
Registration is $900 for the general public and $500 for University of California students and employees. Registration includes instruction, materials, flight practice and lunches. Scholarships are available.
This year DroneCamp is being held in conjunction with the Monterey Bay DART (Drones Automation & Robotics Technology), which is holding an industry symposium on Friday, June 21. DroneCamp participants get a $50 discount to attend the symposium.
Wine grape growers in the San Joaquin Valley who want to switch from hand pruning to mechanical pruning won't have to replant their vineyards to accommodate machinery, according to a new study published in HortTechnology by University of California Cooperative Extension researchers. Instead, growers can retrain the vines to make the transition, without losing fruit yield or quality.
Mechanical pruning reduced labor costs by 90%, resulted in increased grape yields and had no impact on the grape berry's anthocyanin content. That's welcome news for growers because the cost of re-establishing a vineyard in the region is roughly $15,600 per acre.
“We found that growers do not have to plant a new vineyard to mechanize their operations,” said Kaan Kurtural, UC Cooperative Extension specialist in the UC Davis Department of Viticulture and Enology. “We have proven beyond a doubt that an older vineyard can be converted to mechanization. There is no loss in yield during conversion and post-conversion yield is better and fruit quality is equivalent to or better than hand-managed vines. The economies of scale are evident in the savings per acre and per vine as depicted in the balance sheet provided with the newly published paper.”
The research was conducted in an 8-acre portion of a 53-acre, 20-year-old Merlot vineyard in Madera County. After completion of the research project, the grower converted the rest of the 53-acre vineyard to single high-wire sprawling system. Many other wine grape growers have followed suit.
The Wine Group, which manages 13,000 acres of vineyards across Central California, is establishing new vineyards and converting old vineyards for mechanical pruning and suckering, said vineyard manager Nick Davis. Davis, who works closely with Kurtural and the UCCE viticulture advisor in Fresno County, George Zhuang, said the company greatly values the UC Cooperative Extension research that is guiding the changes.
“I think extensionists are undervalued,” Davis said. “We lean on them for applied research, which has been wonderful. They offer us what we can't provide ourselves.”
More than half of all California wine grapes are grown in the San Joaquin Valley. Worker shortages, rising labor costs, low returns and occasional droughts are driving wine grape growers to seek innovative ways to sustain their businesses.
“To help growers maintain the profitability of their vineyards, we're studying the use of machines to reduce the number of people needed to perform tasks like pruning,” Zhuang said.
“Because the canopy architecture and yield characteristics of mechanically pruned vines are different from vines that are hand-pruned, the water and fertilizer requirements for the mechanically pruned vines can be quite different. So we are studying the yield and fruit quality of grapes produced on different rootstocks in mechanical pruning systems in the San Joaquin Valley,” Zhuang said.
The Madera field study was conducted for three consecutive seasons in the hot climate conditions typical of the San Joaquin Valley. In this area, traditional vineyards are head-trained to a 38-inch-tall trunk above the vineyard floor and two eight-node canes are laid on a catch wire in opposite directions and two eight-node canes are attached to a 66-inch high catch wire. Although this traditional training system can work for mechanical harvesting, it doesn't accommodate mechanical dormant pruning and shoot removal with limited success in other mechanical canopy management operations.
To accommodate mechanical pruning and shoot removal, the vines were converted to a bilateral cordon-trained, spur-pruned California sprawl training system, or to a bilateral cordon-trained, mechanically box-pruned single high-wire sprawling system.
The latter option proved to be the most successful system for mechanical pruning in the San Joaquin Valley.
On Feb. 19, San Joaquin Valley grape growers are invited to discuss the latest UC research on mechanical pruning, trunk disease and rootstocks with UC Cooperative Extension advisors and specialists in Fresno. Growers will also get to observe a field demonstration of grapevines being mechanically pruned.
“We have been hearing from California grape growers that they are having a hard time finding enough workers to maintain their vineyards and increasing labor cost starts challenging grape-farming economic sustainability so we are studying the use of machines to reduce the number of people needed to perform tasks such as pruning,” said George Zhuang, UC Cooperative Extension viticulture advisor for Fresno County.
Gabriel Torres, UC Cooperative Extension viticulture advisor for Tulare and Kings counties, will discuss plant diseases that may result from trunk injuries and pruning wounds from the machinery.
Karl Lund, UC Cooperative Extension viticulture advisor for Mariposa, Merced and Madera counties, will discuss how to select rootstock for a vineyard that will be mechanically managed.
“Because the canopy architecture and yield characteristics from mechanically pruned vines are much different from hand-pruned vines, the water and fertilizer requirements of mechanically pruned vines can be quite different,” Zhuang said. “Therefore, performance of different rootstocks under mechanical pruning system is critical to achieve both yield and fruit quality targets of grape production in the San Joaquin Valley.”
Kaan Kurtural, UC Cooperative Extension viticulture specialist in the UC Davis Department of Viticulture and Enology, will go over the basic principles of mechanical pruning of wine grape vines.
From 8 a.m. to 10:30 a.m., UC Cooperative Extension advisors and specialists will meet with growers in a Golden State Vintners vineyard at 7409 W Central Ave in Fresno.
“We will discuss current grape issues and the future of viticulture in the valley,” Zhuang said.
The meeting, which is being co-hosted by UC Cooperative Extension and San Joaquin Valley Winegrowers Association, is free. For more information, contact Zhuang at email@example.com or (559) 241-7506.
Glenda Humiston has always been involved in rural issues from her days growing up on a cattle ranch to her current efforts to connect rural communities to more resources as University of California vice president for agriculture and natural resources.
In recognition of her contributions to sustain California as a place to create and thrive and to bestow to future generations, Humiston will be presented the 2018 California Steward Leader Award by California Forward and the California Stewardship Network at the California Economic Summit in Santa Rosa on Nov. 16. She currently serves on the 2018 Economic Summit Steering Committee and is the Action Team co-lead for Working Landscapes and co-chair of Elevate Rural California.
She has been involved with the California Economic Summit from the beginning, chairing the Access to Capital Action Team at the first Summit in 2012. To raise awareness of innovative options for financing projects, she founded and chaired the California Financial Opportunities Roundtable and was instrumental in producing the Access to Capital Guidebook, a widely used resource for small business owners, policymakers and financial institutions.
Humiston served as deputy undersecretary for natural resources and environment at USDA from 1998 to 2001 under President Clinton. She then managed the Sustainable Development Institute at the 2002 World Summit for Sustainable Development in South Africa and the 2006 World Water Forum in Mexico City. In 2009, Humiston was appointed by President Obama to serve as the California State Director at the United States Department of Agriculture (USDA), Rural Development.
Working landscapes a significant sector of the economy
He added, “The fact that rural issues are on the agenda, the fact that we're talking about ecosystem services and the contributions that Working Landscapes can make in terms of meeting the Economic Summit's million-acre feet of water goal, Glenda has done a tremendous amount to make that possible.”
Sonoma County Supervisor James Gore agreed. “Glenda is a powerful and relentless advocate for triple bottom line prosperity. She has championed and delivered in every position I have seen her in. As one of the Co-chairs/Steering Committee for the Economic Summit, she has ensured that working landscapes remains a driver for rural prosperity.”
“Glenda embodies what CA Forward and the California Stewardship Network are all about: empowering regional hubs to own their own future,” added Gore, who served with Humiston at the U.S. Department of Agriculture as presidential appointees under President Obama.
Her work on rural issues continues. “Our Ecosystems Services Team has done a fantastic job in highlighting the opportunities for ecosystem services to be a powerful policy instrument as well as a compensation instrument for landowners to ensure that the many benefits from ecosystem services are available to the general public,” Humiston said. She added that recommendations from last year's Summit may be included in upcoming legislation.
Biomass, rural broadband and water infrastructure
As co-chair of Elevate Rural California, she is working on three main areas: biomass, rural broadband and water infrastructure. “We identified those issues at last year's Summit and worked this year to identify where the opportunities were as well as options to pursue. We're bringing that information to the Summit this year to get people to really rally around those three issues and move forward working on implementation.”
To support these initiatives, Humiston is working to enhance economic development efforts throughout the state by ensuring that the research and resources of the University of California are delivered to every single community in the state. UC Cooperative Extension is in 70 communities and serves all 58 counties; its mission is to conduct research and extend knowledge that supports food security, healthy environments, science literacy, youth development and economic success in a global economy.
Humiston, who joined the university in 2015 and clearly loves her work, said, “I love the mission of the programs I oversee for the University of California. This work is critical as we seek solutions to the challenges we all face: climate change, invasive species, changing workforce demands, water management and more.”
Vision based on partnerships
Her vision is really based on partnerships. “I also see great opportunity for increased collaboration between UC, CSU and the Community Colleges," she said. "Working together we can offer more robust support for innovation, regional industry clusters, new business opportunities and other aspects of local economic development; we can bring a lot of resources to the table. Working with the California Economic Summit allows us to leverage the resources of various regional initiatives as well as other sectors; this helps all the Summit's efforts to be more successful.”
As for the award, Humiston is humbled. “It's quite heart-warming to be selected by people I respect for something like that and certainly to be in the company of people who have won it in past years,” she said.
Previous recipients of the California Steward Leader Award include former California State Senator Becky Morgan, California Emerging Technology Fund's Sunne McPeak and Van Ton-Quinlivan, vice chancellor of the California Community Colleges.
Humiston will receive the award on Friday, Nov. 16, at the annual gathering of the California Economic Summit in Santa Rosa.

Open Farm started in 2016 at Terranova Ranch with the support of a research grant from the California Energy Commission (EPC-14-081). In 2017, the event grew to a wider gathering with peer-reviewed presentations organized by UC ANR and field demonstrations led by West Hills College. Both organizations are involved in the broadband initiative to bring better broadband services in the Central Valley.
“The future of ag tech innovation and implementation on the West Side depends on access to broadband internet in the fields,” said Terry Brase, ag science instructor at West Hills Community College. “West Hills is proud to partner with UC ANR to champion an initiative that would make this possible for local growers.”
PowWow Energy, Pumpsight and WiseConn Engineering are examples of companies that have worked with the farming community and established application programmable interfaces (API) that allow farmers to protect their data and get the different applications to talk to each other.
“It makes the lives of growers easier, not harder,” said Olivier Jerphagon, founder and CEO of PowWow Energy, Inc.
The three vendors went through the Water Energy Technology (WET) center at Fresno State, which is one of the incubators in California connected by the VINE.
“Agriculture needs standards to support the better integration of systems and data to make using technology easier and less expensive, while protecting the privacy of farms,” said Gabe Youtsey, UC ANR chief innovation officer. “We need to work together across industry, academia and government to share best practices and form partnerships to solve real problems and adapt the integration of software and data to the needs agriculture. This is why we started the VINE.”
The VINE – the Verde Innovation Network for Entrepreneurship – is a connected community of innovators and resources that sustainable agriculture and food innovators can leverage, including incubators, research labs, field testing facilities, mentors and industry experts.
“The food and agriculture industry is changing fast, and for an organization like ours to add value, we have to understand the diversity of innovation that is happening in the industry,” said Helle Petersen of Fresno State's WET Center. “The VINE community helps us navigate the field, and leverages the many assets of our region. The Open Farm is one of those opportunities, a unique event that brings together researchers, farmers, industry and others to share their knowledge, best practices and find opportunities for partnerships.”
