Could Northwest growers have an opportunity to cultivate potentially displaced California almonds in the future? Photo: Flickr user Nicholas D under CC BY-NC 2.0.
California cultivates roughly two-thirds of the nation’s fruit and nut crops, including virtually 100% of the US almond supply. Growing demand and high profit-per-acre have driven a doubling in almond acreage in the Golden State since 1995, including a nearly 100,000-acre increase in almond plantations between 2011 and 2015, despite that period coinciding with the most severe drought in the state in a millennium.

Want to understand what carbon fertilization is, and what it could mean for the American West? Take a look at Linnia Hawkins’s (Oregon Climate Change Research Institute) post discussing research on whether the American West could become both drier and greener under climate change, which would affect wildfires. Linnia’s full article is in the Climate CIRCulator.

One challenge I struggle with when sharing research focused at global scales is how to tease out answers to questions that are meaningful in the region and at the scale I work in. My approach is to focus on how the big picture results sketch out, and think about what it all means (even when the specifics are not exactly right, which they rarely are). Hopefully I’ll be successful in this article about a paper I co-authored, on agriculture in temperate drylands (I define these below) at a global scale. Led by Dr. John Bradford at the U.S. Geological Survey, we looked at temperate drylands across the world, and explored how rainfed (non-irrigated) agricultural areas could shift as the climate changes. Read on, and see if I convince you that wheat growers in the Pacific Northwest should care about these results. Continue reading

As climate and agriculture researchers we’re constantly learning from farmers who we interact with. Our conversations with dryland wheat producers in the inland Pacific Northwest have shown us that many farmers are very skilled at managing for multiple risks at once and making decisions under various kinds of uncertainty. Climate models project substantial warming by mid-century (Figure 1) as well as more frequent storm events and more extreme minimum and maximum temperatures in the future. At the same time, a higher concentration of CO2 in the atmosphere may contribute to more rapid crop growth. As more detailed and sophisticated models of climate change and crop dynamics are developed, it is increasingly clear that managing under observed and projected climate change impacts will require new perspectives for farmers and other agriculture sector decision makers. Those involved in agriculture will need to develop their understanding of climate-related hazards and poise themselves to take advantage of emerging opportunities linked to a changing climate.

Weather in the Northwest has gotten more variable. We have recently experienced drought for two years followed by flooding in 2017. The 2015 drought coincides with future climate projections for the Northwest: warmer temperatures leading to lower and earlier melting of snowpacks. Though trees are locally adapted to climate and can tolerate moderate changes, rapid and large changes in climate may be beyond the capacity of some species. As we saw in 2015, longer and drier growing seasons affect tree regeneration, growth, and mortality. This poses challenges for foresters, which Chris Schnepf discussed in a recent article.

“This is the first good news I’ve heard about climate change” was among the feedback received after delivering a talk about changes expected for Pacific Northwest’s agriculture. The audience was primarily ranchers attending the Northwest Grazing Conference in Pendleton, Oregon this past May. Scheduling conflicts prevented the talk’s author, Chad Kruger, director of the Center for Sustaining Agriculture and Natural Resources from attending, and with some trepidation I agreed to present the topic on his behalf.
For many Americans, climate change is at best an abstract challenge, seemingly serious but without immediately obvious specific threats to one’s life and business. To the skeptic, it is a political football and a dark conspiracy, some nefarious excuse dreamed up to gain economic and political advantage for one interest group over another. With this in mind I attempted to summarize and translate the results of Northwest-focused climate research to an audience I expected viewed the topic at large with some level of hostility.

“Family forest owners own a large portion of forests in many PNW regions” (Photo – C. Schnepf)
Many westerners presume any forest they drive by is managed by the U.S. Forest Service. But nationally the largest portion of forests are owned privately. Even in the West, key regions have a very high percentage of private forests. For example, over half of the forests in the Idaho Panhandle are private.
Some people debate whether forestry should be considered part of agriculture. Like farmers, forest owners and managers are discerning how to adapt their management to a changing climate. But forestry in North America starts from a different point than most cropping systems. Continue reading

One of the best things about my work is that it connects me with researchers from a wide range of disciplinary backgrounds who are committed to conducting science that informs natural resource management decisions. I’ve been fortunate to work with WSU researchers studying regional climate change impacts for nearly 6 years now, and over that time many of my academic colleagues have developed new skills related to communicating their research to diverse audiences. I’ve also witnessed scientists’ growing interest in learning from stakeholders who make decisions about managing agricultural and natural resources “out there in the real world”. Continue reading
