The impact of climate change on cattle producers in the Northwest is not expected to be as extreme as other regions of the United States. According to a recent study led by Shannon Neibergs and published in Climatic Change, Northwest producers have a comparative advantage because droughts will be less severe in the Northwest and they have access to feed via extensive irrigation systems than can mitigate the effects of drought. That’s compared to the rest of the United States, though. But what impacts can livestock producers expect here? Can they continue business as usual? Probably not, but there are clear options moving forward, conclude Neibergs and colleagues. Continue reading

What will climate change look like on Pacific Northwest rangelands, which cover a huge area of our region? It will undoubtedly have complex impacts on the physical environment, environmental stressors, socio-economic factors, and the animals, plants, and other rangeland organisms. Recently, I took a look at the literature to see what the state of the science is relating to rangelands’ vulnerability to climate change. While there are a number of relevant studies that I mention below, I focus in this article on one of the few quantitative analyses, led by Matt Reeves, that updates Reeves’ previous work that was also discussed on agclimate.net.

Water is a precious resource in the Columbia River Basin, and climate change could lead to changes in factors that affect how to most efficiently allocate water to the many uses and values in the region, a challenge even now. This future is not bleak, however. A research team led by Jon Yoder at Washington State University has been funded to develop new technologies to help decision-makers improve how they use water to meet the diverse needs of farms, people, fish and the rivers themselves. Check out this article on their research plans into smart market technology, seasonal forecasting, and automated monitoring of agricultural (and other) water use.

The National Integrated Drought Information Systems, via Drought.gov, working with a team of Northwest stakeholders, have just put together and released a new Drought Status Update that highlights current drought conditions that are affecting the Northwest. Continue reading

Multiple climate projections for the Pacific Northwest suggest that our region’s agriculture will be impacted as our climate continues to change. Are farmers preparing for these changes? And if not, why not? These are the questions I hoped to answer as part of my research.

Turns out that understanding how changes in climate are affecting the demand for water for irrigation in the Columbia River Basin is really important for our overall understanding of how water use and management may need to change in the future. Check out this Washington State University newsletter article on a recent study into this topic, led by AgClimate’s sometime-contributor Kirti Rajagopalan.

The contrast between the arid west—rangelands, wheat, conifer forests, irrigated agriculture—and the Midwest’s Great Plains—corn, soybean, prairies—is well known. There is a somewhat abrupt line separating arid from humid, close to the 100th meridian. That line is now shifting, as climate change affects temperatures, precipitation, and wind patterns that control that arid-to-humid line. Take a look at a recent study from Columbia University on how the line is shifting eastward from the 100th meridian. And you might want to start with the blog article “The 100th Meridian, Where the Great Plains Begin, May Be Shifting.”

Many countries enthusiastically plant trees that are not native to their shores. One of the best examples is New Zealand, which has extensive plantations of genetically improved Pinus radiata, a species native to northern California and known here as Monterey pine. If you noticed pine forests that humans, elves, and orcs scurried through in the Lord of the Rings movies (filmed in New Zealand), you were likely looking at planted, non-native trees.

Yes, more on snow… because there’s less snow. Read Nathan Gilles’s article in the Climate CIRCulator, that discusses research that found that mountains in the western United States have seen snowpack decreasing by an amount similar to the size of Lake Mead over the last 60 years.
