USDA SARE (Sustainable Agriculture Research & Education) recently published a new resource for land managers and those who advise them titled, “Cultivating Climate Resilience on Farms and Ranches.” This resource outlines some of the challenges that farmers and ranchers will face as climate change leads to more extreme and variable weather. While the resource is national in scope, there is a great table that briefly explores the observed and expected changes in weather across seven U.S. regions, including the Northwest (Table 1).

Tools for Reducing the Increasing Forest Fire Risks

It was impossible to watch all the media coverage of the California fires last year, with many homes and forests burning, and not be moved. When large destructive fires like this hit, people have a natural desire to put some meaning to it. A variety of voices spoke of the changes in climate as being the culprit. Some pointed to fuel build-ups that were heavier than those forests had historically. Others pointed to people moving into parts of the landscape that were very fire prone, and suggested it was only a matter time before homes burned in forest fires. As with so many things, all these explanations for the impact of the fires contain some truth. Continue reading

Could Wood Plastic Composites Motivate More Investments in Climate-Friendly Anaerobic Digestion?

By Karen Hills

Picture this future scenario: it’s a hot summer day and you are sitting with some friends on their deck enjoying a cold beverage. You notice they recently replaced their deck and, interested, you ask about the decking material they used, only to find out that it’s made partially out of . . . manure from dairy cows! Surprised? Work done by researchers at Washington State University investigated this potential method for adding value to an agricultural waste product.

Shared Data is a Key Part of Integrated Floodplain Management in the Puyallup Watershed

By Jordan Jobe, Center for Sustaining Agriculture and Natural Resources, Washington State University

In the Puget Sound Region, it’s clear that climate change impacts will involve changes in precipitation that will impact agriculture, especially agriculture in floodplain areas (Mauger et al. 2015). However, it’s not yet known how precipitation pattern changes will combine with changes in stormwater run-off and sea-level rise… and how these changes might differ between different watersheds. Flood risk reduction folks want this information so that they know how to properly size new culverts. Fish folks want this information to place and design salmon habitat restoration projects.

Engaging Climate Science through Citizen Science Apps

Trying to understand how climate is changing, and how these changes affect the crop yields, forest growth, water from melting snowpacks, and all the other parts of our natural world, is very challenging. Increasingly, some of the primary tools for understanding these phenomena are models.

One of the biggest misconceptions about models is the idea they are not based in the real world – that they are just theoretical constructs, untethered to actual measurements. There are models like that – even philosophers are playing with models these days. But most of the models used in the natural sciences depend on empirical data – measurements of things like temperature, precipitation, crop yields, tree mortality, and many other attributes.

Check it out: The State of the Science on Climate Change in the Pacific Northwest

By Gabrielle Roesch-McNally

The Fourth National Climate Assessment (NCA4) was just released on November 23, 2018. The Global Change Research Act of 1990 mandates that the U.S. Global Change Research Program (USGCRP) provide a report to Congress and the President just about every four years. This report focuses on the human welfare, societal and environmental impacts associated with climate change and variability across 10 regions in the U.S., and across 18 topics of national significance. Many collaborators across the Northwest participated in writing for the Northwest chapter. In this chapter, we outline five Key Messages that illustrate how climate change will impact different aspects of life in the Northwest (Figure 1):   Continue reading

Flexibility is Key to Northwest Cattle Production’s Future Success

By Laurie Houston

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

Northwest Rangelands – Where Do our Climate Vulnerabilities Lie?

By Georgine G. Yorgey

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.

Irrigation Efficiency: What Do the Researchers Say?

Are more efficient irrigation systems good for farmers and the rest of society? This is a question that may receive a straight “yes” from many of our readers. However, agro-hydrologists and others know that there’s more to the discussion. Continue reading
