- (Public Value) UCANR: Safeguarding abundant and healthy food for all Californians

Last month, I had a chance to attend the Society for Range Management annual convention in Denver, Colorado. Among the symposia I attended was one entitled "Transforming ranching through precision livestock management on extensive rangelands" - fancy title, right?! But despite the lengthy (and overly academic) title, I found the talks to be outstanding! And the possibility for using technology to improve livestock management presents an exciting opportunity!
The first speaker was Dr. Mark Trotter from CQ University in Queensland, Australia. He suggested that cooperative extension can and should play an important role in the development and use of new technology. First and foremost, this technology should have economic value for producers - either by increasing revenue or reducing costs. Dr. Trotter also suggested that extension should guide the development of technology and help test the hardware in real-world settings. Extension should help test the animal behavior algorithms that make the technology relevant in production settings. Finally, extension can help prepare the industry for the widespread adoption of these new technologies.
The most exciting technological developments, at least to me, are those that can help make labor more efficient. Dr. Trotter and Dr. Derek Bailey (from New Mexico State University) talked about new applications for global positioning system (GPS) technology and ear tag mounted accelerometers. Researchers are finding that these systems can predict when cattle or sheep will give birth and can even alert a producer about a calving or lambing problem. Other researchers are using these systems to detect diseases and predation impacts. Trotter and Bailey also talked about the potential for using this kind of technology to place water troughs in areas that will facilitate more efficient forage use, as well as helping managers predict when livestock need to move to fresh pasture.
The final speaker was Dr. Tony Waterhouse, professor emeritus from Scotland Rural College. He spoke about the need for durable technology: "Sheep break things a bit; cows break things a lot," he said. He has experimented with technology that records a ewe's proximity to specific lambs as a way to match a ewe with her offspring (often a difficult task in extensive range-based sheep production systems).
At least for me, technology will never replace the need for people to manage livestock. These are complex biological, economic, and social systems - the rancher's "eye" will always be critical. However, I do think that there may be ways - in the not too distant future - where this technology can help our eyes see patterns and behaviors we couldn't see previously. Stay tuned! I hope to begin testing some of this technology in the coming years!
In the meantime, here are some links to several of the technology firms mentioned in the symposium:

Between PG&E's public safety power shutoffs and a lack of precipitation, October was an interesting month for foothill ranchers. Many areas received a germinating rainfall in mid-September; most of that new grass withered in an October that saw only 0.02 inches of rain in Auburn. And while many operations are used to having irrigation water turned off in mid-October, the lack of rain and multiple blackouts by PG&E made getting drinking water to livestock a challenge. Last week, I sent a survey to area ranchers to help get a handle on the impacts from the public safety power shutoffs. While I'm still collecting data (if you're a rancher and have not yet participated in the survey, click on this link: http://ucanr.edu/oct19livestockwatersurvey), I wanted to share some preliminary results.
To date, 39 people have completed the survey. Most respondents receive water from the Nevada Irrigation District; an equal number use groundwater. Many operations use water from more than one source. Most of the operations responding are in Placer County, although a number of operations raise livestock in more than one county. Of those responding, 41 percent purchase winter water from their water district(s).
Here are more details on the responses so far:
