National Climate Assessment

The US Global Change Research Program released the Third National Climate Assessment a couple of weeks ago. Unlike some other recent climate report releases (USDA’s Climate Change and Agriculture Report, the Northwest Climate Assessment and the IPCC AR5 Draft Report), this one seemed to have been picked up to a much greater extent by the major national and regional news agencies. In fact, I’ve been interviewed by two separate NPR reporters in the region for my interpretation on what the Assessment means for PNW agriculture. Part of the reason for the media attention likely stems from the much more aggressive promotional messaging – specifically stating that climate change is hurting the economy now (I’ll have more to say on that idea in a future post).

When engineering a green solution has gone too far…

Posted by Chad Kruger | May 12, 2014

I’ve seen a lot of crazy ideas in the realm of agricultural technology and even toyed with a few crazy ideas myself. Crazy ideas seem to have an appeal in our society that exceeds any rational expectation for the likely success or concern regarding the downside of any given technology. Perhaps this is because people are always looking for the next revolutionary technology like tractors, hybrid seeds, and solar fence electrifiers. Or perhaps it’s because we’re hard-wired to expect technological silver bullets to solve distinctly human problems. In fact, I suspect the reason that our own crazy (and not quite perfect) idea for a household-scale biogas reactor is among the most visited pages on the CSANR website is because it conjures up images of this infamous science fiction idea:

Who wouldn’t want to have that? Read more »

Summer nights are getting hotter faster than summer days. What does it mean for agriculture?

Posted by Chad Kruger | May 8, 2014

Nick Bond, the Washington State Climatologist, pointed out an interesting observation at a meeting I attended last week. For summers from 2000-2010, nighttime temperatures (T-min) in many locations in the Pacific Northwest have shown a strong warming trend while daytime temperatures (T-max) have shown a general cooling trend (Panel 1).   Each circle on the map is scaled based on the station’s temperature trend with red indicating increasing temperature and blue decreasing. This could be part of the reason I’ve had trouble sleeping at night in recent summers – more below!

The disconnect between the production and consumption of food

Over the past several months we’ve seen: a freak early-season snow storm in the Dakotas that killed tens of thousands of cattle that could take affected ranchers more than a decade to recover from, continued and expanding drought conditions in the corn belt of the Upper Midwest, extended drought cutting off irrigation water in the “produce basket” of the Central Valley of California, massively destructive storms and flooding in the Gulf Coast, and a deadly virus killing piglets in more than half the country. In spite of this, we’re just finally seeing reports that the price of food is creeping higher – a whopping 0.4% two months in a row! – with the increasing price of bacon the one most people are complaining about.

Climate Change or Climate Variability: which matters more for crop production in the PNW?

Posted by Chad Kruger | April 18, 2014

Several modeling studies have been conducted in recent years to estimate the potential impact of climate change on future crop production.  These studies generally indicate that the magnitude of the potential near-future impact (through 2050) is relatively modest for most crops in the Pacific Northwest – and usually somewhat positive.  Climate variability, on the other hand, already impacts crop yields at magnitudes equal to or greater than those projected for mid-century, and often in a very negative way.  So why do these studies focus on future climate if current climate seems to be the bigger concern?

When MANAGING for soil carbon really pays

Posted by Chad Kruger | September 27, 2013

In August I published a post describing one mechanism by which increasing soil organic carbon (SOC) can lead to direct financial benefit on irrigated farms. In that particular example, the agronomic value of the carbon could be more than 10X greater than the potential value of a “carbon credit”.  While it’s clear that there are general benefits to increasing SOC, in reality the specifics of each situation, such as the climate, soils, and management system, will all have an impact on monetizing any benefit. In this post I’ll examine a different case example published by some of my colleagues working at the WSU Cook Agronomy Farm, a dryland wheat farm near Pullman, Washington. Read more »

Considering the vulnerability of our food system to climatic disruptions

Posted by Chad Kruger | September 17, 2013

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 »

When soil carbon sequestration REALLY pays

Posted by Chad Kruger | August 15, 2013

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 »

Anaerobic Digestion: Beyond Waste Management

Posted by Chad Kruger | June 13, 2013

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!

Where are all the apple blossoms?

Posted by Chad Kruger | May 2, 2013

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!

Just don’t expect to see many apple blossoms. Full apple bloom was well over a week ago (see Wenatchee World). Read more »
