water

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.

Scientists from the University of Texas at El Paso (UTEP) are working with stakeholders to determine the course their research will take.  The result, they say, is better science that is more useful to end users – and the scientists learn a lot, too.

Rather than have their own science-based questions direct their research, Dr. Josiah Heyman and his research partner Dr. William Hargrove will let stakeholders – the actual users of their science – point the way.  According to Heyman, this “participatory approach” is science for the public’s sake, not for the scientists’ sake.  The two lead a multi-institutional, multi-national project that is tackling drought-driven water supply issues in the Southwest.

The Schultz Fire of 2010 started with an abandoned campfire. High winds blew the flames into neighboring trees and brush, igniting a wildfire that would grow to 15,000 acres of the Coconino National Forest and threaten residents near Flagstaff, Arizona. In the following days 750 homes would be evacuated. It took 300 firefighters several weeks to contain the fire in the steep slopes North and East of the city.

Flagstaff had been spared from fire, but not its aftermath. In July 2010, heavy flooding due to monsoonal rain events on the burned-over slopes of the San Francisco Peaks caused an estimated $133-147 million in damage to neighborhoods just outside the city.  A 12-year-old girl, Shaelyn Wilson, was killed when she was swept away in a flash flood.

The mission of the Forest Service is to “sustain the health, diversity and productivity of the Nation’s forests and grasslands to meet the needs of present and future generations.” The provisioning of water resources – notably clean drinking water and flood control – is central to this. Growing demand for our water resources, spurred by population growth, and the effects of climate change further challenge the Forest Service to successfully meet the needs of present and future generations.

In the western United States – where water flowing from national forests makes up nearly two-thirds of public and commercial water supplies – water scarcity and wildfire threats have galvanized diverse stakeholders to invest in healthy headwaters. Local communities, public utility companies, businesses, non-governmental organizations and state and local agencies are investing in watershed restoration to avoid catastrophic economic losses.

Planning for the future of the nation’s water resources is more important now than ever before as severe drought grips the West, affecting heavily populated areas and critical agricultural regions. Forests generally yield huge quantities of water—much more than crops or grasslands—but also use a lot of water during the growing season, so some land managers wonder if forest thinning could boost water supplies to people and ecosystems in a changing climate.

U.S. Forest Service researchers from the Eastern Forest Environmental Threat Assessment Center and the Coweeta Hydrologic Laboratory tested this idea and found that the results were not so cut and dried. Their findings were recently published in a special issue* of the journal Hydrological Processes.

With drought reaching historic proportions in Western states, America needs people with both knowledge and experience in water management to help ensure that forests and working lands stay ahead of the effects of climate change.

The U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA) is partnering with land-grant universities, minority-serving institutions, federal agencies, and other organizations to get qualified students out of their classrooms and into the field where they can pick up real, hands-on experience in natural resource protection.

Imagine a rice farmer in Arkansas altering his water management techniques to deliver water more efficiently and use fewer days of flooding, allowing for more precise water and nutrient management while maintaining consistent yields. After a decision by the California Air Resources Board (CARB), in addition to improving water quality and reducing water use and nutrient input costs, that Arkansas farmer now has the option of selling carbon credits to large regulated emitters in California.   

In 2012, California put in place a cap-and-trade program for greenhouse gas emissions, one of the most aggressive climate change programs in the world. Last week’s groundbreaking vote by CARB adopted the first crop-based agricultural offset protocol, designed to reduce methane and nitrous oxide emissions from rice production. Methane and nitrous oxide are potent greenhouse gases emitted through the cultivation and fertilization of rice fields.

July in America.  It is summer time and school’s out. It is about vacations and maybe a trip to the beach. It is Independence Day—the 4^th of July—and parades and fireworks.  It is about barbecues, hotdogs, and burgers. 

2015 marks America’s 239^th birthday.

July is also the month for another important birthday in America—passage of the Morrill Act on July 2, 1862, which established the land-grant university system, ensuring access to education for all people.

This year I have had the pleasure of visiting a number of urban agriculture operations. From California to Cleveland, the ability of individuals to realize the multidimensional benefits of agricultural production and leverage them in an urban context has been nothing short of amazing.

This past week I visited a University that is heavily involved in both the research and extension aspect of urban agriculture -- right in the backyard of the Department’s Washington, D.C. headquarters. The University of the District of Columbia’s (UDC) Muirkirk Agricultural Experimentation is located about 20 minutes north of the school’s D.C. campus. Upon arrival I found everything from activists passionate about learning how to best provide their neighbors with fresh produce, to researchers developing improved hydroponics systems; and even students working with community organizations on rice varieties suitable to be grown in urban areas.

Getting from Point A to Point B is sometimes a difficult task; that’s why we have maps.  However, making maps is not always easy, either, especially when the image you’re trying to capture is carried on the wind.

For nearly 40 years a coalition of government, education, industry, and other organizations has worked to monitor “precipitation chemistry” – in other words, tracking the makeup and whereabouts of acid rain.  Their latest efforts have resulted in maps that indicate how nitrogen deposition in the United States threatens aquatic life in the Gulf of Mexico.

In the High Plains of Texas, water reigns. The area is one of the most productive agricultural regions in the world, making a reliable water supply key to the area’s rural economies.

The High Plains draws its water from the Ogallala Aquifer, an underground aquifer that spans eight states. Currently, the use of groundwater from the aquifer is unsustainable as withdrawals for cities, farms, ranches, industries and other uses exceed the natural recharge of the aquifer.
