Each year CSANR administers an internal competitive grant program called BIOAg to fund new research and education projects focused on improving the sustainability of agriculture in Washington State. To date, through BIOAg and precursor internal grant programs, CSANR has funded 150 projects – many of which have led to significant new investments of extramural funding to further advance these ideas. Over the course of the program [and within each year] we have funded projects ranging from basic science to applied research to extension and educational products and we’ve always been able to maintain a good blend across this continuum.  Read more »

Is this the new climate normal?

I will remember winter 2014-2015 as the winter of seemingly never-ending fog, and snow that didn’t stick. That sucks on so many levels, particularly for what it will mean come July and August when we have a serious water problem in the Inland Northwest. I keep getting asked “is this climate change” and “is this what we have to look forward to?” Read more »

Does an anaerobic digester cost too much?

Anaerobic digestion (AD) with methane capture and conversion is the most straight-forward, bankable strategy for reducing agricultural greenhouse gas emissions. In fact, it is the only agricultural carbon mitigation strategy that has achieved wide-spread acceptance in a variety of voluntary and mandatory carbon mitigation policies. In a sense, it is the closest thing to a “silver bullet” carbon mitigation solution that exists in agriculture. However, AD still has limited overall market penetration in US livestock production systems, in large part because of the perception that it is really expensive technology. Read more »

On why I might be wrong

Posted by Chad Kruger | November 4, 2014

In two prior posts (threats and variability), based on our research, I have argued that climate change is not likely to be a major cause for concern for agricultural production in the Pacific Northwest until at least mid-century. A little bit of warming and a little bit of CO2 elevation is actually positive for most crops in the PNW. In this post, I’m going to tell you why I might be wrong. Read more »

Is PNW warming human caused or not? Does it matter to agriculture?

Posted by Chad Kruger | September 29, 2014

The observed temperature records of the US Pacific Northwest show a small, but statistically significant amount of warming of just over 1 degree F since the year 1900. A paper published in March of this year by Abatzaglou, Rupp and Mote (2014) used a multiple linear regression model to “tease out” the contributions of different influences on climate and “to apportion trends to internal climate variability, solar variability, volcanic aerosols, and anthropogenic forcing [a.k.a. human greenhouse gas emissions]”. Unsurprisingly, the finding of this study was as expected:

Anthropogenic forcing was a significant predictor of, and the leading contributor to, long-term warming; natural factors alone fail to explain the observed warming.

FY15 BIOAg Request For Proposals released

Posted by Chad Kruger | September 25, 2014

BIOAg logoThis week, CSANR released its annual BIOAg Program request for proposals for new research and extension projects. The RFP can be found here.

This competitive grant program is the key mechanism that CSANR has to engage a broad, interdisciplinary spectrum of WSU faculty in projects that further the development, understanding, and use of biologically intensive and/or organic principles, practices, and technologies to improve the sustainability of agriculture and food systems in Washington State.

Are we at risk of a megadrought in the PNW?

One of the caveats I always state when presenting the results of our research on projected climate change impacts on PNW agricultural production is: we don’t yet know if climate change will disrupt our existing regional climate cycles. To date, the climate forecasts for our region indicate a future where climate change amplifies the current cycles – resulting in a future that is warmer and possibly slightly wetter on average, but still keeping the pattern of relatively short-cycling between wet and dry periods. These wet and dry periods rarely last for more than a couple of years. Read more »

The biggest threat to food security?

Posted by Chad Kruger | September 9, 2014

In a recent interview that covered the gamut of oft-cited threats to agricultural sustainability and food security (drought, food safety, energy disruption, economics, terrorism, chemical pollution, genetic pollution, impacts on pollinators, soil erosion, climate change, etc.), I was asked which threat I thought was the biggest. I was completely stumped. For every threat that came to mind as “the big one” I could come up with at least two arguments why a different threat was bigger. Read more »

Have we drastically underestimated the productive capacity of plants?

Posted by Chad Kruger | August 28, 2014

A new paper published in Environmental Science & Technology (DeLucia et al., 2014) suggests that scientists have drastically underestimated the earth’s theoretical potential to produce biomass – by as much as 2 orders of magnitude! That’s going to take a minute to wrap my mind around.

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).
