While the nationally televised Seahawks game was delayed for lightning Sunday night, much of the inland Pacific Northwest braced for the fourth major storm event this summer, with warnings for high winds and severe dust storms, massive electrical storms, heavy rainfall with localized flash flooding, mudslides and extensive power outages. Fortunately, my family did NOT get struck by lightning during this storm as we did in the August 10th storm and this storm also doesn’t seem to have sparked any new wild fires! In light of the on-going flood events in Colorado this week, it looks like we probably had it easy this time with only some inconveniences that should be corrected in the next 24-48 hours. However, given that September is National Preparedness Month, this seems like a good opportunity to highlight a recent commentary paper that I co-authored with some colleagues around the country evaluating research needs regarding the vulnerability of the food system to climatic disruptions. As with most commentary articles, this activity included a review of published literature coupled with expert assessment of where there are gaps in our understanding of vulnerabilities. Read more »

The dog days of summer have arrived in Eastern Washington – with daily temps reaching the high 90s every day. This is the second extended stretch of heat in the region this year. Read more »

After nearly a decade of work, we’re finally ready to “show off” our achievements in improving the environmental performance of dairies. Take a look at the brief video we recently produced describing our efforts and join us in the field on July 10th!

This weekend marks the 93rd Washington State Apple Blossom Festival in Wenatchee – one of the true highlight events celebrating agriculture and community in the state. And, after a few weeks of unseasonably cold temperatures, frosts, freezes and high winds, the weekend weather outlook is dazzling – sunny, mid-80s and calm! So, if you don’t have plans this weekend, come on over and enjoy a great community event in the fantastic spring weather!

Agriculture is a seasonal endeavor. And so the weather during each season can profoundly impact farmers and the crops they produce. Now, researchers at University of Idaho and Oregon State University are providing some new insights on how the seasonal climate has changed over the last century in the PNW, and how it might change over the next 50 years.

In the comment string of my original post Reflections on Savory, reader Rondi Lightmark asked a very legitimate set of questions:
How much closer are we going to get to catastrophes far worse than the Dust Bowl while scientists sit around and debate the merits of a new idea? Allan [Savory] has adequately demonstrated the success of his work to warrant significant support for implementing his methods on a large scale. What do we have to lose if we do? Who can answer that question?
While I responded to the comment in that post, I’ve had several similar questions raised in other settings recently so I thought this topic justified its own more general post. Do we wait for more data or act in good faith based on what we know? Here is the rub between science and action on challenging issues like climate change, soil erosion or desertification. I completely understand the frustration that it often seems as though science moves “too slowly” to enable us to respond effectively to increasingly complex global problems. On the question of climate and global carbon emissions, scientists like James Hansen (Hansen et al., 2008) have actually indicated that we may, in fact, have waited too long to take serious action and that we may be too late to curb the more detrimental global effects of a changing climate. With this in mind, it makes acting seem more urgent and often leads us to make significant societal investments in ideas that don’t have solid quantification or evaluation to support. Read more »

USDA recently released a report that provides a comprehensive interpretive review of the scientific literature on the impacts of climate change on agriculture in the U.S. This report was undertaken in response to the soon to be released 2nd National Climate Assessment – an effort that reviews the impact of climate change on several sectors of the U.S. economy. The USDA report, entitled Climate Change and Agriculture in the United States: Effects and Adaptation, can be accessed from the website of the USDA’s Chief Economist .

A recent paper (Olson, 2013) finds a number of long-term studies were wrong about no-till practices building soil organic matter and thus sequestering carbon. The problem, says Kenneth Olson, soil scientist at the University of Illinois, is how the studies in question measured the gains or losses in soil organic carbon (SOC; organic carbon is about 50% of soil organic matter by weight). According to Olson, these long-term studies made soil carbon measurements during or at the end of the experiments which compared the results of no-till (NT1 in figure 1) to moldboard plowing (MP). They then concluded that carbon was sequestered in the soil under no-till but not in tillage systems. The figure below represents what Olson says these studies measured. Read more »

If you pay any attention to the climate change topic, you are likely seeing an increasing number of headlines and announcements related to various climate change reports. In the absence of context, this seeming proliferation of reports and events could be somewhat confusing. This post is a very quick introduction on what this is all about, with information about how you can learn more.

Managing Change Northwest recently brought Allan Savory of the Savory Institute to the Pacific Northwest to speak to the Washington Cattleman’s Association, the Tilth Producers of Washington, and a special workshop and keynote in Seattle for consumers. CSANR co-sponsored Savory’s PNW tour because we thought he brought a challenging message that many in our region needed to hear. Below is the second of a two-part post of my reflections on what Savory had to say when he was here.
Part 2: The Philosophy
In my previous post on this topic I shared my thoughts on the controversial nature of the science behind Allan Savory and Holistic Management (HM). In this post, I will focus on my view of the philosophical challenge Savory presented when he was here. Read more »
