Although it’s no longer her job, Anna Miller still takes time to volunteer for the Lee County Water Festival every spring in Auburn, Alabama. The annual event has attracted hundreds of fourth graders with lessons on aquifers, the water cycle and water filtration, since it first began in 2004.
“Students learn about their environment; they learn about water and how precious it is,” said Miller. Read more »
USDA's Economic Research Service, and other researchers, analyzed the similarities and differences of the Chesapeake Bay and the Baltic Sea to help preserve the water quality of each.
Situated on two different continents and separated by thousands of miles, the Chesapeake Bay on the East Coast of the United States and the Baltic Sea in northern Europe face remarkably similar problems. Both are relatively shallow basins of brackish water. Both marine areas suffer from eutrophication–pollution caused by introduction of chemical nutrients. For both water bodies, agriculture is the single most important source of those nutrients, and governments have implemented policies to reduce nutrient loads and improve marine ecosystems.
Researchers at the Natural Resources Institute Finland, USDA’s Economic Research Service, and the University of Helsinki have analyzed the similarities and differences between the institutional settings and protection policies of the Chesapeake Bay and the Baltic Sea. The aim was to identify avenues for reducing the cost of meeting water quality objectives. The very different political and institutional histories of the jurisdictions within the respective watersheds provide both contrasts and similarities. The six U.S. States in the Chesapeake watershed have a common political history and operate under Federal environmental law. The Baltic watershed is made up of 14 nations whose intergovernmental relations are strongly influenced by Cold War legacies. Yet current policies in both watersheds rely heavily on voluntary approaches to control agricultural runoff. Read more »

Water is a precious resource and will become scarcer as the human population continues to grow. In many areas, climate change is expected to affect weather patterns. In general, the wetter areas are expected to get wetter and the drier areas are expected to get drier. This year, California’s drought has highlighted how important it is for land managers and producers to exercise best practices to increase water quality and quantity so there is enough to go around.
This year, USDA participated in the 7th Annual World Water Forum in Daegu, Republic of Korea. Every three years, the World Water Council hosts the Forum and develops the program in cooperation with the private sector, governments, industry, international governmental organizations, nongovernmental organizations and academic groups.

For the foothill yellow-legged frog, breeding can be a challenging matter.
It is the only true frog in western North America that breeds exclusively in streams, preferring warm stream edges. Its eggs can be swept away with spring rains and rapid currents, so a relatively long breeding season allows mates to wait until weather and water conditions offer the best chance for eggs to develop and hatch in this dynamic environment.
But yellow-legged frogs face a new challenge in a Northern California river managed for agriculture, energy, and habitat for steelhead, Chinook salmon and coho salmon. Read more »
Nothing is a basic as clean pure water for this generation and generations to come.
It’s a fact most of us learned in grammar school. More than seventy percent of the earth’s surface is water. On this 45th Earth Day, I can’t help but be proud to recognize the work that USDA Rural Development is doing to improve water quality and availability in Rural America. Today, USDA is announcing over $112 million in loans and grants to rural communities across the country for better water and wastewater systems.
To recognize Earth Day, today I visited the rural community of Henderson, Maryland. The town’s water system recently failed completely, leaving the 146 residents of Henderson without water. However, Rural Development stepped in to help. USDA is providing the town with a $175,000 Emergency Community Water Assistance Grant to make critically needed repairs to the system. Read more »
USDA-ARS agricultural engineers Susan O’Shaughnessy and Nolan Clark adjust the field of view for wireless infrared thermometers mounted on a center pivot irrigation system. The wireless sensors are used to measure crop canopy temperature for indications of water stress.

With droughts becoming more severe, water tables getting lower and an increasing demand for water from growing suburbs and cities, farmers know they need to use water more sparingly. That’s why recently patented technology developed by USDA’s Agricultural Research Service (ARS) scientists in Texas is so important.
Steve Evett, Susan O’Shaughnessy, and their colleagues at the ARS Conservation and Production Research Laboratory in Bushland, Texas have spent years trying to help growers maximize water in a region that depends on the Ogallala Aquifer, a massive underground reservoir under constant threat of overuse. They recently developed two complementary technologies that offer practical ways to ensure that crops get only as much water as they need. Read more »
