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 →

Most of our moms urged us to “eat our fruits and vegetables,” and multiple studies confirm this motherly advice. For instance, the U.S. National Institutes of Health recently reported that consuming more fruits and vegetable results in reduced mortality. Unfortunately, the same report tells us what we already know: most Americans don’t consume anywhere near the five servings a day needed for maximum health benefits.

But what if we did? Could America’s farmers grow all of that additional produce? Continue reading →

Soil has been called “the living skin of the Earth.” The effort to maintain the health of this “living skin” in Washington got a boost in 2021 when the State Legislature passed the Washington Soil Health Initiative with a $2.1 million annual allocation (half of which goes to Washington State University). Washington State is just one of many states in the U.S. where interest in soil health has resulted in initiatives focused on maintaining soil health on working lands, but, notably, no other state’s soil health initiative is investing as much into research as Washington’s. Soil health is defined by the USDA NRCS as “…the continued capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans.” Soil health is often described as a “win-win” with positive outcomes both on-farm and off-farm. For example, on-farm benefits include improved soil tilth, nutrient cycling, water holding capacity, and disease suppression. Off-farm benefits include reduced soil erosion and improved water quality, as well as reducing the impact on our climate, most directly through carbon sequestration.

The win-win nature of soil health allowed the Washington Soil Health Initiative to gain support from commodity groups in Washington as well as environmental organizations. Continue reading →

Climate change is expected to alter both the availability and demand for water. In the western United States, roughly 80% of surface water is allocated to agricultural uses, and the pressure to find more efficient ways to manage water is on, especially in drought years. Eastern Washington is no exception: the mountains in this region are relatively low in elevation, meaning that as the region warms, temperatures will cross that 32°F threshold more frequently, more precipitation will fall as rain rather than as snow, and snowmelt will occur earlier. Because the Pacific Northwest relies on snowpack for much of its summer water supply, this could create challenges for managing water. While previous articles have focused on the likely timing and availability of water in the Columbia River Basin, in this article I focus on water markets, or the transfer or leasing of water and water rights from one user to another. These markets provide a tool that could potentially help reallocate water to where it is critically needed during times of shortage. Continue reading →

In this era with record-setting temperatures multiple years in a row, scientists are looking for methods to sequester carbon to slow the process of climate change. Agriculture plays a key role in not just the global economy, but also the global carbon cycle: cropland soils have the potential to be either sinks or sources of greenhouse gases, notably carbon dioxide. The conversion of native ecosystems to cropland agriculture has resulted in enormous carbon losses, estimated to be between 20-70% of the original carbon stored in native soils in the US. The Pacific Northwest is an agricultural powerhouse: in 2017, Washington, Idaho, and Oregon produced $22 billion in agricultural production on over 42 million acres. That’s a lot of soil. I recently read a white paper by Georgine Yorgey and colleagues at Washington State University titled “Carbon sequestration potential in cropland soils in the inland Pacific Northwest: Knowledge and gaps,” that summarizes research on carbon sequestration in the inland Northwest. It turns out that it is not a one-size-fits-all answer: the potential of certain croplands to either release or sequester carbon depends on climate, the cropping system, the soil type, and other factors. Fortunately, though, some soils do have great carbon sequestration potential. Continue reading →

Climate Friendly Farming Policy Considerations for the Inland Pacific Northwest

Quote: America’s farmers, ranchers, and forest landowners have an important role to play in combating the climate crisis and reducing greenhouse gas emissions, by sequestering carbon in soils, grasses, trees, and other vegetation and sourcing sustainable bioproducts and fuels.” - President Biden’s Executive Order on Tackling the Climate Crisis at Home and Abroad

https://www.whitehouse.gov/briefing-room/presidential-actions/2021/01/27/executive-order-on-tackling-the-climate-crisis-at-home-and-abroad/

Efforts are underway at the federal level to combat climate change on the agriculture front. USDA has just finished a “listening period” to help develop and refine actions they may implement to accomplish this. Just what those actions may be and what effects they may have on the day-to-day operation of Pacific Northwest farmers is an understandable cause of some uncertainty and trepidation.

Recently I spoke with a farmers’ coop manager who asked what programs or policies are likely to be put into effect and whether long time direct-seeders would stand to benefit or lose out. Our discussion (summarized and edited) highlights a few important questions: “If the greatest gains in carbon sequestration are going to be made in the most organic matter-depleted fields, how will those who have already stockpiled organic mater to near a maximum point benefit?” and, “Will there need to be a system of soil carbon auditing or compliance enforcement?” and the inevitable big one, “Inland Pacific Northwest agriculture is very different from Midwest agriculture, will these new policies unfairly benefit some farmers over others?” Continue reading →

I explored opportunities to reduce environmental impact related to food preparation and food waste in previous AgClimate.net articles. However, transportation in the food supply chain is a significant contributor to carbon emissions: all the transportation and miles in between the farm and your plate are part of the journey of fruits, vegetables, and all of your favorite foods. Those food miles and methods of transportation look different today than they did several decades ago. The “last mile” that your food travels through before it lands at your door, otherwise known as the stage from the processor or retailer to the consumer’s hands, is changing too, and it has the potential to be a great opportunity for greenhouse gas emissions reduction. Americans are spending 100 billion dollars a year on online groceries alone. The home delivery meal kit industry is valued at 1.5 billion dollars in the United States and is experiencing a growth rate of 25 percent annually (Heard et al.). While 23 percent of Americans were buying their groceries online in 2016, projections indicate that up to 70 percent of consumers will make the switch by 2024, partially due to the rise in home deliveries throughout the COVID-19 pandemic (Food Marketing Institute). What do all of these at-home deliveries mean for the environment? How are our decisions on the manner in which our food arrives at our dinner table impacting the so-called “last mile” emissions?

While many scientists, producers, and consumers recognize the importance of quantifying the carbon footprint of agriculture, most efforts focus on on-farm activities. The journey food takes before it lands on a consumer’s plate is complex and requires looking beyond the farm gates: as it turns out, the consumer’s plate plays an important role in the overall environmental footprint of a given product. In a recent article, we explored insights related to preparation of French fries from a study led by Ranjan Parajuli on the relative impact of different parts of the supply chain (on-farm, processor, retail, and consumer) for fresh and processed potato and tomato products. Here, we examine another aspect of supply chain impacts of potato and tomato products: food waste. The results indicate that waste contributes significantly to greenhouse gas (GHG) emissions.  Continue reading →

Washington State is taking steps to foster environmental stewardship in agriculture using an alternative approach to direct regulatory oversight. Twenty-seven counties in Washington have opted into the Voluntary Stewardship Program (VSP), which requires them to self-assess (with state oversight) whether voluntary management actions are maintaining or enhancing Critical Areas. Critical Areas include wetlands, fish and wildlife habitat conservation areas, critical aquifer recharge areas, frequently flooded areas, and geologically hazardous areas. Most counties cite riparian conservation measures as a strategy to maintain or enhance at least one type of Critical Area. Riparian conservation measures, like planting or allowing natural vegetation to grow, can also address the impacts of climate change, providing shade to cool water in the stream, improving habitat for species stressed by climate change, and possibly helping moderate extremes in moisture availability year-round. Conserving small land areas can thus have a large impact for mitigating the effects of climate change. The question is, how can we quickly determine if these measures are working, and meeting the goals of the VSP? Continue reading →
