Word cloud from 2022 article titles, with 2022 Top Reads! overlaid2022 has come to a close, and 2023 seems to have revved up and is roaring along. We are still early enough in the year, though, to look back on 2022 and reflect on what you, our readers, found worthy of your time and attention. Here are the three most read 2022 articles, and three still-popular articles from earlier years. It is worth taking a look. I was struck by the breadth of topics and production systems these articles discuss, which is reflective of the variety in the Pacific Northwest that we explicitly try to cover in AgClimate.net. All these articles also have something in common: they discuss science-based resources that can help agricultural and natural resource professionals understand the implications of a changing climate, and explore options to be better prepared for the future. That is what AgClimate.net is about. Enjoy these top reads in 2022! Continue reading →

Farmers growing crops such as wheat and corn might be more interested in leasing some – rather than all – of their water to support instream flows in times of water scarcity, which are likely to occur more frequently as the climate changes.

If you are a Washington agricultural producer who has a water right and wants to lease your water to another user, you are currently allowed to either lease your entire water right and fallow your land (that is, not use any of the water yourself) or not lease and use your full water right for crop production. The option of leasing a part of your water right (partial leasing) does not exist.

Introducing an option for partial leasing could make more farmers willing to participate in water markets, and thus expand markets’ potential as a tool for meeting diverse water needs, especially as climate change increases the likelihood that water supplies won’t be sufficient to meet all demands, all the time. For example, farmers might lease some of their water to support instream flows in times of water scarcity, which are likely to occur more frequently as the climate changes. Although there are a number of challenges that would need to be overcome to make partial leasing a reality (I discuss those later), we started by asking the question of whether the potential benefits of partial leasing are big enough to make it worth bothering to invest the time and money it would take to overcome those challenges.

Extensive sagebrush steppe rangelands play a crucial role in the success of Northwest ranching operations, allowing livestock to graze throughout the spring and summer months on fresh forage. However, as wildfire frequency and size increase in sagebrush steppe due to climate change, burned areas of varying sizes within these rangelands will need to be rested as they recover. Ranchers and rangeland managers will need new, cost-effective methods of separating cattle from these sensitive, burned areas on public rangelands while still grazing neighboring unburned areas.

Virtual fencing presents a compelling climate change adaptation option for doing just that. Continue reading →

Exploring the Nexus of Solar Energy and Agriculture: How Do We Invest in Climate-Friendly Energy While Ensuring the Future of our Food Supply?

Given ambitious state and federal goals for reducing greenhouse gas emissions, the pace of solar energy development is accelerating rapidly in the Pacific Northwest, placing significant pressure on the region’s agricultural land and its stewards. According to a US Department of Energy study, by 2050, 90% of solar energy will come from utility-scale projects in rural communities (Ardani et al. 2021). Our team at American Farmland Trust (AFT) recently looked specifically at solar development as a contributor to farmland loss (Hunter et al. 2022). In addition to the nearly 200,000 acres at risk of conversion to urban and low-density residential development, Washington State could lose as many as 86,000 acres to solar development by 2040 (Figure 1).  We estimate that about 80% of that development – or 68,800 acres – will occur on agricultural land. While this may not sound like a lot given Washington’s vast agricultural landscape, it’s equal to or more than the total acreages used by some flagship crops: barley (70,000 acres), hops (43,000 acres), cherries (39,000 acres), or onions (19,000 acres).

 The opportunity to lease land to solar developers may have considerable appeal for a farmland owner given the many challenges that face our region’s producers: unstable commodity markets, rising property values, labor shortages, climate change, and lack of successors, just to name a few. But solar leases also carry significant risk for the landowner and for the land. Here we discuss two approaches AFT is taking to help ensure that the interests and values of agricultural lands and landowners are equitably considered at all levels of decisions around solar development.

“It’s difficult to make predictions, especially about the future.” So goes an apparently ancient Danish aphorism also mistakenly credited to a wide range of humorists, from Yogi Berra to Mark Twain – and even to a Nobel Laureate, Niels Bohr. Whatever its origins, it is undeniably true. I will discuss an approach for hedging our bets against an uncertain future. I will start with an example where this is already being done, and then we can tackle soil carbon. Continue reading →

Check it out: Another La Niña? What Does That Say About Climate Change?

Leave a reply

By Sonia A. Hall, Center for Sustaining Agriculture and Natural Resources, Washington State University

The weather we experience any given year is the product of a complex combination of short-term variations (think cold fronts), mid-term cycles (think of El Niño and La Niña years as an important example affecting our region), and long-term trends (think of warming due to climate change). This complexity can lead to years that do not fit either with what’s happened historically, or with what climate change science leads us to expect. Our recent experience with snow in April is an example of such “weirdness.” So I found this news article from the University of Washington really interesting. Check it out. The article discusses a study that suggests that Map of the PAcific Ocean showing cooler (blue) and warmer (red) temperaturesclimate change is, in the short term, favoring La Niña years. This is counter to the expected trend towards more frequent El Niño years as the world warms. Bottom line, there are aspects of the changes in sea temperatures that we are seeing that are not well captured in our current climate change models, which in the short term load the dice for La Niña, though in the long term we expect a switch to El Niño. And this is a great window into how the use of models in science works – weirdness is an important step in identifying what questions we still need answers to, and attracting curious minds to try to answer them.

 

Here’s the study the article discusses. It has a good plain language summary:

Growing up, I remember my grandfather bringing my family fresh Honeycrisp apples from his orchard in the Chelan area, describing the qualities that made them special. As an orchardist, my grandfather always strived to have delicious, high-quality produce coming from his orchards. My grandfather is not alone in this quest; growers across the state are looking for ways to enhance the quality of their crops. As climate change progresses and temperatures rise, fruit quality could be affected: climate change has been linked to delayed fruit ripening, low fruit quality, low fruit yield, sunburn, and more.  Regulated deficit irrigation (RDI) is one possible way to combat some of these impacts.
