NWAL holds first climate resilience workshop

The end of a multi-year drought has created new challenges for farmers on tribal lands in Nevada, according to participants in a Climate Resilience Workshop held by Native Waters on Arid Lands (NWAL) on May 9, 2017. After above-average winter precipitation during the 2017 water year, drought conditions have given way to an excess of water in parts of the state, causing problems such as flooded fields, delayed planting schedules, and invasive weed growth.

The workshop, which was held in conjunction with Nevada FRTEP‘s Nevada Indian Summit, provided an opportunity for NWAL researchers and tribal members to share information about the impacts of the recent drought and the current winter’s water supply on traditional and production agriculture in Nevada. A full agenda for the workshop and Summit is here.

More than 35 people attended the one-day workshop, including members of the Duck Valley Shoshone-Paiute Tribe, Walker River Paiute Tribe, Pyramid Lake Paiute Tribe, Yerington Paiute Tribe, Fort McDermitt Paiute and Shoshone Tribe, Duckwater Shoshone Tribe, the Elko band and South Fork band of the Te-Moak Tribe of Western Shoshone, Cheyenne River Sioux, the University of Nevada Cooperative Extension, University of Nevada, Reno, Utah State University, University of Arizona, the Desert Research Institute, Western Regional Climate Center, Great Basin Landscape Conservation Cooperative, USGS and the USDA.

This workshop for members of Nevada tribes was the first of three climate resilience workshops that will be held by Native Waters on Arid Lands. In future months, there will also be workshops for Arizona/New Mexico tribes and Utah tribes.



Reflecting on precipitation patterns

Nina Oakley, Regional Climatologist with the Western Regional Climate Center at the Desert Research Institute, provided an overview of recent drought and precipitation patterns in Nevada.

Nevada experienced the wettest Dec-Feb conditions in a 123-year period of record during 2017, Oakley said, as atmospheric river storms dropped moisture throughout the region. At present, according to the US Drought Monitor, the state is drought-free, with only a few areas that are “abnormally dry”.

During the last two decades, Oakley explained, we’ve experienced three notable periods of drought, each followed by a wet year: a drought from 2001-2005, a wet year in 2006; a drought from 2007-2010, a wet year in 2011; a drought from 2012-2016, and a wet year in 2017. Although conditions across Nevada are currently quite wet (the April 1 snowpack was 110 to 220 percent of normal across the state), it seems likely that drought conditions will return again in future years. Oakley also noted that summer 2017 is expected to be warmer than average in Nevada.


Roundtable discussion: Impacts of recent drought and wet years

A roundtable discussion led by NWAL team members Staci Emm (University of Nevada Cooperative Extension) and Kynda Curtis (Utah State University) asked workshop participants to reflect on the impacts of recent years (2012 to 2017) on tribal water supplies and traditional and production agriculture.

During drought years, impacts to farmers included:

  • Reductions in crop production/crop yields and loss of income.
  • Loss of entire fields of alfala, which now must be replanted (alfalfa can generally be harvested for five years without replanting, and can be cut several times during the growing season).
  • Less water available for irrigating, which resulted in fewer cuttings of alfalfa than normal.

As conditions across much of Nevada have changed from very dry to very wet, impacts reported by workshop participants included:

  • An increase in noxious weeds in their fields, including species they haven’t seen before which were brought in by flooding.
  • Swampy conditions in growing fields, or fields that are completely underwater. This delays/prevents planting, and may create problems with mosquitos.

Other impacts experienced by workshop participants included:

  • An increase in the length of the growing season (with more warm days earlier in the spring and later in the fall), which requires more irrigation water to support crops.
  • Day-to-day temperature variations.
  • Weeds such as Canada thistle, Musk thistle and Scotch thistle can ruin an entire field of alfalfa; these pop up after the field is plowed for planting.

To adapt to the climate conditions experienced during recent years, some farmers have made changes to agricultural practices, including:

  • Planting triticale (a wheat/rye hybrid that is drought-tolerant, high in protein, and must be replanted annually). Workshop participants reported planting this crop instead of alfalfa, or planting it in the same field as alfalfa. They reported that it grows so thick that it crowds out weeds. It can be planted in fall and harvested in spring, requiring no irrigation.
  • Planting experimental crops, like teff. Teff is a fast-growing annual and good for animal feed, but doesn’t do well in the cold. It is an Ethiopian grain that is high in iron and protein. Teff can also be eaten by people.
  • Adjusting the timing of planting. If fields are too wet, crop planting occurs later in the season.
  • For community gardens and small-scale family gardens, hoop house projects have become popular.

Conference participants were asked to reflect on which changes worried them the most, economically and culturally. Concerns included:

  • The potential for increased numbers of crickets and grasshoppers, which feed on alfalfa and other crops. This has happened in the past after similar cycles of drought and wetness.
  • Difficulties related to planning and figuring out what to spend money on during times of uncertain climate conditions.
  • Concerns about planting alfalfa (a five-year crop) given the recurring cycle of drought periods that has occurred during recent years.
  • Concerns regarding the behavior of honeybees. Bees form a tight ball in the hive to stay warm during winter, and “unball” when the weather warms. As we experience more warm days early in the spring, bees may unball too early and be killed by a late freeze. Colony Collapse Disorder is also a concern.
  • The cost and risk involved with growing experimental crops. The cost of buying equipment for planting new crops can be prohibitive.

Opportunities for future adaptation:

  • Buy a cuber. Weeds like Canada thistle, Scotch thistle and Musk thistle can ruin an entire crop of alfalfa; sometimes the field must be burned to kill the seeds. Equipment called a “cuber” could be purchased, which turns hay or alfalfa into small cubes (pellets) and cooks the seeds in the hay so that they are no longer viable. This equipment would be expensive, but maybe a good investment for a group of farmers to share.
  • Grow native plants for seed. In Nevada, seeds of native plants are needed/required by some federal agencies for post-fire rehabilitation in burned areas. Penstemon, basin wildrye, and indian ricegrass were a few options mentioned; farmers should check and make sure there’s a good market for whatever they decide to grow. Comstock Seed is one organization that buys seed.
  • Develop a cooperative marketing strategy. Small farmers from tribal lands must compete in the market against large producers. Can we create a marketing strategy that groups together people from various reservations to collectively market goods?
  • Apply for funding from government programs.


Past and future climates of the Southwestern US

After the roundtable discussion, Dr. Michael Dettinger, a Senior Hydrologist with the USGS and member of the NWAL team, gave a presentation about past climates of the southwest and predictions for future change. In his talk, Dr. Dettinger provided an overview of what scientists have learned about changes in climate in the Northern Hemisphere and Great Basin over many thousands of years, including evidence of temperature changes and ancient megadroughts, with information obtained from sources like tree rings, flood sediments, sediments/microfossils, geochemistry and ice cores.

In recent times, CO2 levels in the earth’s atmosphere have spiked dramatically. Temperature projections show that increases of 3-9oF degrees are likely by the end of the century, Dettinger said, and scientists are already observing changes such as an increase in the amount of precipitation falling as rain (versus snow), warming temperatures, earlier snowfed streamflow, and lower snowpacks across the west. In the NWAL study area, he has created climate projections for individual reservations that show changes in temperature and precipitation through the end of the century. According to the projections, we should expect warming across the region and an increase in the range of variability of precipitation (the large storms will get larger, and the number of dry days will increase as well).


Roundtable discussion: Making climate data accessible

NWAL team members Dr. Alex Lutz and Christine Albano led a discussion between researchers and tribal members to gather feedback about how to best make climate data accessible and useful for climate adaptation planning, water management and agricultural decision-making.

Suggestions from workshop participants about data delivery needs included:

  • NWAL should provide climate predictions that go six months out, to help farmers figure out when to plant or harvest crops.
  • Provide weather data that goes six months back. This is what farmers need to give farm service agencies.
  • Send information by email, in quarterly updates that are short and to-the-point.

Overall, farmers expressed interest in data related to:

  • For farmers of alfalfa, warmer weather results in faster growth, and there seems to be no upper temperature limit. Cooler weather results in slower growth.
  • Mid-summer precipitation. Rain that falls on a crop after it is cut is very bad, but between cuttings, rain is good for the crop.
  • Changes in snow versus rain.
  • Changes in the timing of snowmelt runoff. In some regions, farmers have no water storage, and rely entirely on runoff for farming.

Several farmers also provided information to the research team about some of the challenges and logistics involved in growing the following crops:

  • Alfalfa: High temperatures are not a concern for alfalfa farmers, because warm temperatures result in faster growth. In southern Nevada, they get ten cuttings per year in 120oF temperatures. As long as there is enough water, it grows well. When weather is cooler, alfalfa growth slows down, and frost shuts down growth. If you’re harvesting alfalfa for cattle and horses, you want about 10-15% of the field to bloom. For dairy quality hay, you have to cut it before it blooms.
  • Teff: An annual. Does not do well in the cold.
  • Triticale: An annual. Does well when planted in the fall because it likes cooler weather and winter moisture. Farmers who plant this crop early in fall can let cattle graze on it and then later let it go for hay. Alfalfa and triticale can be planted in the same field, because they are harvested at different times.
  • Birdsfood trefoil: A perennial. Makes good feed for cattle, needs very little water. Grows up by Susanville in the wild, and in Gardnerville in pastures. A legume.

Roundtable discussion: Adaptations in agriculture

In the final roundtable discussion, NWAL team members Dr. Beverly Ramsey (Director, Earth & Ecosystems Science, DRI) and Trent Teegerstrom (Native Programs Director, University of Arizona) asked workshop participants to share thoughts about how to adapt agriculture to increasing variability of water supplies and warming temperatures. Much of the discussion focused on the use of hoop houses.

Hoop house projects have become popular on many reservations.

  • In AZ, people are using hoop houses to grow fruit trees at higher elevations.
  • In NM, people use hoop houses to start plants, so that they can get them into the ground at the right time to align with water resources
  • Hoop houses must be built with the right materials, built for UV resistance. Plastic breaks down over time; maintenance is needed.
  • Hoop houses are useful in growing nutritious, locally produced food. Can be used to grow food year-round, depending on the crops. A great asset for reservations that are located a long distance from a grocery store.
  • Small-scale family owned hoop houses are working well.
  • For community gardens or larger community hoop houses, it may be best to hire an employee to be in charge of daily operations. Otherwise, there have been problems with maintenance (for example, having someone responsible for opening the vents every day).
  • At lower elevations, or as temperatures warm, you can remove the plastic from the top of hoop houses and put up shade cloth.



Second Annual Native American Nutrition Conference

In closing, Beverly Ramsey encouraged workshop participants to consider attending the second annual Native American Nutrition Conference, which will be held Sept 19-20, 2017 in Prior Lake, MN. This conference is organized by Seeds of Native Health, with talks and workshops focused on native nutrition and food sciences. Beverly attended the first conference, and found it to be a very worthwhile event. Seeds of Native Health also offers scholarships to tribal members and officers. For more information, visit:
