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 →

Basics of Biochar: On-Farm Kiln and Soil Amendment Options
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.

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 →
A number of our articles this year discussed using biochar in agriculture and in forestry. These earlier articles did not delve into the methods to apply biochar on large tracts of forests. You’d expect this to be a much more challenging task than spreading biochar on croplands. Researchers and technology developers are tackling this particular issue, developing a specialized forest biochar spreader. Take a few minutes to check out their Science Spotlights article and their video. Among the details they discuss in the video is a point Chris Schnepf and Darren McAvoy made in their AgClimate article: biochar can use—and store the carbon that is in—those “leftovers” that otherwise get burned, releasing that carbon into the atmosphere.
Topsoil has often been referred to as the “thin skin” of our planet, essential for producing the food that feeds us. Because it’s not easy to create new topsoil, conserving the soil that we have is essential for maintaining our region’s agricultural productivity. Reducing tillage, and leaving residue on the soil surface, is a proven way to reduce erosion. As residues break down, they increase the concentration of soil organic matter at the surface of the soil and help to form soil aggregates—a composite of soil particles that clump or bind together, giving soil its structure. Soil that is aggregated in larger particles is less prone to being eroded by the wind. And soils with more organic matter also benefit the climate, by storing more carbon.

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 →

One of the first ways we expect climate change to impact forests is with the behavior and effects of forest insects and diseases. To assess that, it is important to monitor forests for evidence of insects and diseases that kill trees. Continue reading →
