From wine grapes to cattle and hay, Oregon produces more than 220 different crop and livestock products. About one-quarter of Oregon’s land base (16 million acres) is in agricultural production, and these lands provide opportunities for carbon sequestration and resilient food systems in the face of climate change. However, these lands can also be attractive to developers, especially around urban areas. Because of the foundational nature of land to agricultural and conservation values, our statewide nonprofit organization Oregon Agricultural Trust (OAT) partners with farmers and ranchers to protect agricultural lands for the benefit of Oregon’s economy, communities, and landscapes.

Okay, okay- while baby kangaroos singlehandedly solving climate change is out of the question, the potential for baby kangaroo droppings to help decrease methane emissions is an exciting prospect!
Methane from ruminant digestion is a significant contributor to greenhouse gas emissions in agriculture- we’ve all heard the concern over cow burps, otherwise known as enteric emissions. The relative potency of greenhouse gases is assessed through both their warming potential and with their longevity in the atmosphere. Methane persists in the atmosphere for roughly 12 years while carbon dioxide warms for centuries. While methane’s longevity is significantly shorter than carbon dioxide, methane is about 20-30 times more potent of a greenhouse gas in terms of warming potential (IPCC 2007). Reducing methane emissions, whether from enteric digestion or other sources, provides a significant reduction in warming over a more immediate timeframe than carbon dioxide. It has thus been a priority for policymakers, researchers, and agriculturalists in the effort to mitigate climate change impacts. Proposed solutions for reducing enteric emissions from ruminants range from dietary changes to altering the rumen microbiota through vaccines, though each of these possible solutions is still in development.

When it comes to climate adaptation and mitigation opportunities in agriculture, few (if any) are of greater importance than practices that sequester more soil carbon, which can directly reduce the heat-trapping effects of atmospheric CO2. Boosting soil carbon also has multiple direct benefits for growers, such as increasing yield potential and resilience to both drought and heavy rainstorms.
This is a global challenge, including all producers across the Pacific Northwest (PNW). Its sheer size and scope mandates coordinated action across multiple sectors, including grower groups, the research community, industry, and government scientists. I serve on two such multi-sector groups: Conservation Technology Information Center (CTIC) and Field to Market. Continue reading

The passage of Washington State’s Clean Energy Transformation Act in 2019 mandates an electricity supply free of greenhouse gas emissions by 2045. Large-scale renewable energy projects are one way to achieve this mandate. Solar companies see this as an opportunity and are pursuing projects in the sunniest, least developed part of the state—the Columbia Plateau region. As many of you know, the area boasts some of the most productive farmland and ranchland in the state, as well as many endangered and threatened species and habitats, and Tribal cultural resources.
Concerned about losing these values to large renewable energy developments while acknowledging the need for renewables, the 2019 Washington State Legislature directed the Washington State University Energy Program (WSUEP) to pursue a Least-Conflict Solar Siting project for the Columbia Plateau. The project must be completed by June 30, 2023, and we are in the midst of working with a wide-ranging and diverse set of interests to produce maps that can help us balance the need for renewable energy with protecting Washington State’s productive farmland and ranchland, Tribal rights and resources, and species and habitats. You can assist with the project by reviewing draft maps, which will be available soon. Read on to gain an understanding of this novel and important process. Continue reading

2022 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

A new mandate
Agriculture accounts for an estimated 6.7% of the total greenhouse gas emissions in Washington. Could the Climate Commitment Act pose opportunities to help reduce or offset those emissions? Photo: Leslie Michel.
On January 1st, 2023, major portions of the Climate Commitment Act (CCA) will launch in Washington State. This ambitious law is part of Washington’s plan to eliminate or offset all greenhouse gas (GHG) emissions by 2050. The Washington State Department of Ecology estimates that agriculture accounts for 6.7% of the total emissions in Washington. Despite this sizable GHG contribution, agriculture is exempt from CCA mandates, due to existing laws that already regulate this sector. While it remains uncertain how regulations facing the food manufacturing sector may eventually impact agricultural producers, the CCA will not cap emissions from the production of unprocessed livestock and crops. Does this mean these activities will be entirely unaffected? Continue reading

In the face of climate change, much of the world looks to renewable energy. It offers the promise of preventing some of the worst impacts from climate change while allowing us to continue to live similar to how we do currently. Although we need to change how we live in addition to using renewables, without them, we would need to completely revert to pre-industrial times. However, I can guarantee that as I write this on my laptop in my air-conditioned house at my remote job that that is out of the question. With a power grid that runs off clean energy, the changes and reductions we make in our day-to-day lives have a larger impact. If we choose public transportation over driving, it makes a bigger difference if that train runs off a renewable energy powered grid. If we change to more efficient, long-lasting light bulbs and we use solar to power those bulbs, we are wasting less and not emitting carbon dioxide to power our house. The combination of action and renewables is powerful, but switching to 100% renewable energy has some challenges. Continue reading

This article is part of a series, Climate Friendly Fruit & Veggies, highlighting work from the Fruit & Vegetable Supply Chains: Climate Adaptation & Mitigation Opportunities (F&V CAMO) project, a collaborative research study that was co-led by investigators at the University of Florida and the Agriculture & Food Systems Institute. Other collaborators included researchers at the University of Arkansas, University of Illinois, the International Food Policy Research Institute, the World Agricultural Economic and Environmental Services, and Washington State University. This project identified and tested climate adaptation and mitigation strategies in fruit and vegetable supply chains.

As a child of the sixties, I can still remember our family sitting together to watch the coolest show on television, Star Trek (Figure 1). Every episode began with these poetic words: “Space: the final frontier. These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds. To seek out new life and new civilizations. To boldly go where no man has gone before!”
These words came to mind as I reflect on the conclusion of our five-year project to develop and apply the powerful tools of integrated modeling for a unique purpose: to identify climate adaptation and mitigation opportunities in U.S. fruit and vegetable (F&V) supply chains. Continue reading

The ability to store carbon in soils—to sequester carbon—has been receiving increased attention lately, including on AgClimate.net. Recent posts included articles about potential for croplands in the inland Pacific Northwest to sequester carbon and an article on the emerging carbon markets and their relevance for fruit and vegetable producers. Carbon markets offer the promise of monetizing the benefits of practices that add carbon to the soil, and are also good for soil health. If these markets are effective, they would provide a win-win for producers and environmental interests.
Thanks to the wonders of a zoom-friendly world, I recently attended a mini-workshop hosted by the University of Florida and the Institute of Food and Agricultural Extension where we explored carbon markets. Continue reading

Reservoirs are common infrastructure across the globe, with myriad benefits and costs attached. In the Pacific Northwest, for example, reservoirs are used for water storage, energy production, and flood control, but they impact salmon by blocking passage to spawning and rearing habitat and also lose water to evaporation. However, few people know that reservoirs are also a significant source of greenhouse gases, releasing emissions on the scale of thousands of teragrams (Tg) per year, globally. For reference, the entire U.S. usually emits between six and seven thousand teragrams of greenhouse gases each year. Estimates of reservoir emissions have remained uncertain, though, making it hard to find ways to reduce these emissions. Dr. John Harrison from Washington State University teamed up with colleagues from the University of Quebec at Montreal to try to narrow down estimates of global reservoir greenhouse gas emissions, which could help pinpoint where limiting emissions would be most helpful and illuminate specific methods for doing so.
