Powering Planes through Arrested Anaerobic Digestion

Waste is not glamorous. Just look at the moldy pumpkin leftovers from Halloween and Thanksgiving (yes, there are still quite a few around my neighborhood!) and you know why so many of us prefer to not spend our time thinking about wastes. From an energy standpoint, however, waste contains a largely untapped reserve of resources that can be recycled into the products we utilize daily as consumers. When we recover these materials, we have fewer materials to deal with as waste – and also reduce our consumption of raw materials. So why is waste recovery not a typical component of our infrastructure?

Implications of Shifting Timing in Water Availability in Eastern Washington

The Columbia River Basin has grappled with limited water supplies for decades. This was most noticeable during 2015, when we experienced severe summertime drought across large areas of Washington State, which reduced the amount of water available to meet the region’s demands. The 2015 drought and other recent occurrences of lower water availability are representative of a warmer future with lessening snowpack and earlier snowmelt. In fact, Washington is expected to experience drought again this summer due to rapidly melting snowpack and low precipitation forecasts, underscoring the prevalence of water supply issues for the state.

Sagebrush Shrub-steppe or Cheatgrass Prairie?

Although I work in irrigated agriculture, the views on my morning commute are all sagebrush, or the shrub-steppe as this native plant community is called. And cheatgrass, a lot of cheatgrass. Where there have been recent fires, stands of cheatgrass thrive. Sagebrush, the iconic plant of the shrub-steppe ecosystem, is having a hard time. The combined effects of fire frequency, climate change, and cheatgrass invasion have made sagebrush recovery an uphill battle. Will the shrub-steppe recover to its former subtle beauty, or should we get used to the cheatgrass prairie?

Building the Case for Compost and Carbon Sequestration

In the spirit of “what gets measured gets managed”, there has been recent attention directed to how we can quantify potential benefits of compost as an agricultural soil amendment, and its potential to sequester carbon. Accounting for benefits in a defensible way is one key to creating channels for the most impactful action. The beauty of CSANR often lies in its ability to meet challenges like this where they are, to bring science to bear, and provide pathways forward to sustainable solutions.

A multi-state team is addressing agricultural climate change preparedness through creatively paired conversations in the newly funded “Analogs for Dialogs” grant

When it comes to climate change resilience in agriculture, the question is generally not why agricultural operations should be prepared, but which preparations will be effective? Through this $1.5 million grant funded by AFRI’s Foundational and Applied Science Program, a national team led by WSU’s Center for Sustaining Agriculture & Natural Resources aims to build Extension and USDA Climate Hub professionals’ capacity to answer the “which” within specialty crop systems, and move the bar forward in climate change resilience.

What Do Hurricanes and Soil Carbon Have in Common? The Wisdom of a Multi-Model Ensemble Approach

“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.

Water Markets: The Complexity of Trading Private Rights to a Public Good

WSU researchers are examining water markets and barriers to their adoption as a potential strategy to adapt to climate changes. Those implementing water markets must navigate legal and administrative complexities, a big one being the need to treat water resources as both a public resource and a private property.

Deficit Irrigation Conserves Water in Agriculture to Aid in Combating Water Stress

Washington State has nearly 15 million acres of farmland with around 39,000 operating farms, each producing necessary agricultural commodities. A few of the most well-known crops that are produced and distributed from Washington State are apples, cherries, hops, raspberries, and pears. Even when traveling across the country, I can find Chelan apples, which shows
