Biochar is produced by pyrolysis of woody (technically, lignocellulosic) materials. By controlling the conditions under which it is produced, researchers can engineer biochar to be more effective for particular purposes. In previous articles, I explored work looking at the potential for biochar to draw down atmospheric carbon dioxide and increase water holding capacity in soils. Michael Aniayia (Figure 1) and his colleagues in the lab of Dr. Manuel Garcia-Perez at Washington State University, engineered biochar for a specific purpose – adsorbing phosphate, a nutrient that, because it is also common in wastewater and manure, can pollute waterways. Aniayia’s objective was to evaluate strategies for producing biochar in order to improve its ability to remove phosphate. Continue reading →

Our most recently published case study on resilience to climate change describes Brenda and Tony Richards’ family cow-calf operation in Murphy, Idaho.

Over the last few years at the Center for Sustaining Agriculture and Natural Resources we have developed a range of case studies highlighting individual farmers and ranchers in the Pacific Northwest that are implementing practices or strategies that provide ecological and economic benefits now in addition to increasing resilience to climate change. We’ve discussed some of these case studies in previous AgClimate articles (see those on the use of stripper headers and precision nitrogen). Our most recent series is the Rancher-to-Rancher series, which explores innovative approaches three Pacific Northwest ranchers are using that increase their resilience in the face of a changing climate. Though each case study is specific to the conditions of the particular rancher being profiled, insights and strategies from each case study may be applicable elsewhere.

Check out the most recently published case study, that describes Brenda and Tony Richards’ family cow-calf operation in Murphy, Idaho. Continue reading →

The USDA Northwest Climate Hub and National Drought Mitigation Center are hosting a Northwest Drought Workshop via three virtual sessions on 28 & 30 July 2020. This event is for aimed at USDA agency staff (NRCS, FSA, RD, RMA, FS, etc.) and Federal Partners, including Soil and Water Conservation Districts, Watershed Councils, Tribes, University Extension, and other State and Federal Agencies.

The objectives of these workshops are to get a better sense of drought and how it’s monitored, impacts of drought and interconnections in Oregon, Washington and Idaho, as well as share information and resources to raise awareness about drought and lead to changes in response to dry conditions in the region.

Intended outcomes include: Increasing drought impact reporting; remaining informed on drought status; developing a summary of information shared for adapting to drought conditions; and identifying participant-driven next steps and needs.

The first session will be held on 28 July from 8 am – 11 am PT. Participants will:

  • Learn about the U.S. Drought Monitor, including how it is made each week
  • Hear from local experts about drought in Oregon, Washington and Idaho
  • Learn how to report drought impacts
  • Discuss how drought affects USDA programs

The second session will be held on 30 July 8 am – 11 am PT. There will be an east-side focused session with a panel discussion and peer-to-peer learning about drought adaptation practices for lands east of the Cascades (Eastern Oregon, eastern Washington and Idaho). Panelists and peer-to-peer learning will include agriculture, forestry, and rangelands.

The third session will be held on 30 July 1 pm – 4 pm PT. There will be a west-side focused session with a panel discussion and peer-to-peer learning about drought adaptation practices for lands west of the Cascades (Western Oregon, Western Washington). Panelists and peer-to-peer learning will include agriculture, forestry, and rangelands.

Register via this link. You are welcome to register for as many of the workshops as you’d like, however, attendance is limited, so sign up as soon as possible to secure a spot.

The Lasting Impacts of Wildfire

In 1970, when a large lightening caused wildfire started in the Entiat Experimental Forest in north-central Washington, researchers had already collected 12 years of baseline data on three watersheds. Weather and streamflow (including quantity, quality, and timing of water discharge) had all been recorded. This provided a unique opportunity to study the long-term effects of post-fire recovery efforts on hydrology.

Decades after the fire occurred, Ryan Niemeyer, an adjunct professor in Washington State University’s Center for Sustaining Agriculture and Natural Resources, along with his colleagues Kevin Bladon and Rick Woodsmith, began examining the long-term impacts the fire had on the hydrologic system. His findings, recently published in the journal Hydrological Processes, reveal that fire can affect annual stream discharge, peak flows, low flows, and evapotranspiration even 40 years after the burn.

Are There More Multiyear Snow Droughts in Our Future?

As an environmental scientist, I’ve done plenty of hiking in the western U.S., always with a map, water bottle and list of water sources. In dry areas it’s always smart to ration water until you get to a new source. Sometimes a stream has dried up for the season, or a pond is too scummy to drink from, so your supply has to stretch further than planned. On one memorable hike, I found that a water source was dry. The next one, three miles later, was dry too. And the one after that had a dead bear carcass in it. While one dry water source was tolerable, several in a row created a serious problem.

Something similar is happening to snow resources in the western United States. Scientists have long known that the warming temperatures associated with climate change are diminishing the region’s snowpack, with more precipitation falling as rain, rather than snow. That’s a problem because snowpack is a critical resource, acting as a natural reservoir that stores winter precipitation. Are we likely to face several low snowpack years in a row?

A New Method for Measuring Plant Available Water Capacity Helps Document Benefits of Biochar-Soil Mixtures

Biochar has potential to draw down atmospheric carbon when applied to agricultural soils (as discussed in my previous article on this topic). There is currently not a robust way for farmers to be directly compensated for the benefits to society such drawdown provides. However, researchers have been exploring other co-benefits of using biochar as a soil amendment. One such co-benefit is biochar’s ability to increase the water-holding capacity of agricultural soils, and thus increase plant productivity in situations where water is limiting. However, documenting this effect has been limited by how time consuming and expensive it is to measure plant-available water-holding capacity (PAWC) by standard methods (See Figure 1 A, B, C). In an effort to alleviate this barrier, Jim Amonette at the Pacific Northwest National Laboratory and Washington State University’s Center for Sustaining Agriculture and Natural Resources led the development of a new, inexpensive, rapid method for measuring PAWC of soil-biochar mixtures (See Figure 1 D, E), based on applying a specific level of water potential to a sample using a centrifuge. The sample is supported by a filter membrane fixed midway in a centrifuge tube, thus allowing drainage into the bottom of the tube to occur. Continue reading →

Pacific Northwesterners, especially those of us living and breathing in the inland Northwest, expect wildfires every summer. It’s not about if, but about when, where, and how severe they will be, both in forest and rangeland landscapes. As with many other aspects of natural resource management, climate change continues to add a layer of complexity and uncertainty both in terms of the patterns of fire expected in the future, and in terms of the response of land managers. The USDA’s Northwest Climate Hub’s April 2020 newsletter highlighted the findings of two scientific articles that are addressing questions around future patterns in wildfires and what can be done to prepare.

How Can Long-Term Water Storage Management Mitigate Problems in an Era of Water Resource Deficits?

Figure 1. Managed Aquifer Recharge, like this example for the Merti aquifer shared between Kenya and Somalia, can help provide additional water in periods of water scarcity. The photo is from the Intergovernmental Authority on Development. (IGAD).

The 2015 drought caused more than $700 million in economic losses across Washington State. Even with current water storage management, both in places where rivers, lakes, and reservoirs generally provide sufficient water and in places where aquifers are the most stable water resource across seasons, extreme drought still impacted our economy. While droughts may impact different places with varying intensity, the risk of long-term water scarcity is greater when aquifers provide water today at the expense of tomorrow’s supply. As the region faces population increases and increasing competition for water resources to provide environmental value and economic value, the risk may increase further. So what water management options can help us mitigate the impacts of drought in the future?

In our region, we are experienced in using surface reservoirs as buffers between the naturally variable water cycle and the relatively more consistent agricultural water demand. The less visible buffer underground has often been ignored. Yet interest is growing, as aquifers may also be a useful reservoir over the long term, if managed sustainably. Our research team is evaluating managed aquifer recharge (MAR), an approach that stores water in the aquifer during the snowmelt season, allowing users to pump it for irrigation during periods of water scarcity (Figure 1). We have been asking questions about how to recharge aquifer systems to optimally achieve both short-term usage and long-term water supply sustainability. Imagine that the amount of water recharged into the aquifer becomes your future available MAR entitlement to pump up when needed. The more water that recharges the aquifer, the more effective the MAR will be in mitigating drought impacts. We are interested in answering specific questions, such as ‘What timing of recharge and infiltration area would have been needed for managed aquifer recharge to provide an effective buffer against the 2015 drought?’ or ‘How effective is managed aquifer recharge for maintaining sustainable water supply during single-year drought or even multi-year droughts?’ Continue reading →

Being involved in FireEarth, a large research project exploring what makes communities more or less vulnerable to the impacts of wildfire and its cascading consequences, I am really interested in the complexity of impacts and, just as important, what communities, agencies, and other organizations can do to reduce their vulnerabilities. It is not unusual for the initial hypothesis associated with these questions to be that wildfire risk reduction projects in the watershed upstream and around a community have costs associated with them, and we need to understand those costs—as well as the targeted risk reduction benefits that such projects provide—to make sound investment decisions. Now recent work published by the US Geological Survey and partners explores other advantages of such projects: Continue reading →
