There’s no farming without water. Recent droughts in the United States and elsewhere underscore our need to conserve water in agricultural production, and studies have identified agricultural management practices that help protect water quality.  USDA’s Agricultural Research Service (ARS) researchers are making key contributions to these efforts.

For instance, ARS scientists use moisture information collected by satellites to develop the Evaporative Stress Index.  In 2012, this tool predicted that drought conditions were developing weeks before other drought monitoring networks made the same call. ARS researchers also use satellite data to design methods of estimating rainfall amounts in regions where setting up sampling stations would be a challenge, work that has long-range potential for improving precipitation estimates globally.

This week, USDA and its partners released the results of the eight annual national survey of honey bee losses. The survey shows good news—fewer honey bee colonies were lost this winter than in previous years. According to survey results, total losses of managed honey bee colonies from all causes were 23.2 percent nationwide.

That figure is a significant improvement over the 30.5 percent loss reported last winter, but it is still higher than the eight-year average loss of 29.6 percent and still far above the 18.9 percent level of loss that beekeepers say is acceptable for their economic sustainability.

While we're pleased to see improvement this year, these losses are still too high.

You’ve probably heard that the honey bees in this country are in trouble, with about one-third of our managed colonies dying off every winter. Later this week, we will learn how the honey bees survived this winter. With severe weather in a number of areas in the U.S. this winter, a number of us concerned about bees will be closely watching the results.

While scientists continue work to identify all the factors that have lead to honey bee losses, it is clear that there are biological and environmental stresses that have created a complex challenge that will take a complex, multi-faceted approach to solve.  Parasites, diseases, pesticides, narrow genetic diversity in honey bee colonies, and less access to diverse forage all play a role in colony declines.  To confront this diverse mix of challenges, we require a mix of solutions – the odds are that we won’t find one magic fix to help our honey bees.

During the month of April we have taken a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine.

Ag research month has been an excellent opportunity to showcase all the ways in which USDA is truly the “People’s Department.”

That’s how President Lincoln described it after USDA was established in 1862. More than 150 years later, we continue to find innovative ways to improve agricultural production and create new products to benefit the American people.

During the month of April we will take a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine. For example, finding sustainable ways to produce food for Americans and the growing global population.

Today is Earth Day, which gives us the opportunity to celebrate the magnificence of our planet.  It’s a day to observe and support our environmental commitment to our planet now and in the future.

USDA scientists play an important role in protecting our environment.  Much of our research is focused on finding sustainable agricultural solutions to producing food, feed and fiber to meet our nation’s and the world’s ever-growing demand.  We develop environmentally friendly practices that farmers, ranchers, and others involved in food production can integrate into their operations.

During the month of April we will take a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine, like innovative ways to make food safer.

More than 90 percent of American households have microwave ovens where people heat their food, yet this same technology is seldom used for large-scale production in the food industry.

As home cooks know, microwave ovens do not excel at heating food evenly.  The lack of commercial-scale microwave processing technology is, in part, due to the challenge of designing equipment that is capable of pasteurization – heating all of the food evenly to a predetermined temperature for a certain length of time.  Pasteurization makes food safe to eat, by inactivating bacterial and viral pathogens that can make people sick.

So far, Irvin Arroyo has not strayed too far from the farming world. Growing up, he lived and worked with his parents at a 200-acre vineyard in Madera, California, where he tended the vines and harvested the grapes.

When Arroyo went to college at California State University, Fresno (CSU Fresno), he was given a scholarship to work at USDA’s San Joaquin Valley Agricultural Sciences Center in Fresno as an intern.  The laboratory, now in Parlier, is part of USDA’s Agricultural Research Service (ARS). The scholarship had been established by CSU Fresno and ARS soil scientist Gary Bañuelos to foster minority student interest in science careers.

“Seeing the unseen” may sound like a science fiction movie theme, but it’s actually the real-life mission of USDA scientists who use special high-powered microscopes to view microscopic organisms that play a big role in agriculture.

The facility where these scientists produce the images of the unseen world--from fungal spores to plant cells--is called the Electron and Confocal Microscopy Unit (ECMU) and it’s operated in Beltsville, Md., by USDA’s Agricultural Research Service (ARS).

During the month of April we will take a closer look at USDA’s Groundbreaking Research for a Revitalized Rural America, highlighting ways USDA researchers are improving the lives of Americans in ways you might never imagine.  For example, researching mosquitoes that spread diseases that threaten human health worldwide.

Today is World Health Day, and this year’s theme is vector-borne diseases—those diseases spread by organisms like insects, ticks and snails.  Significant vector-borne diseases in the Americas include dengue fever, malaria, leishmaniasis, lymphatic filariasis and schistosomiasis.

One of the most egregious offenders is the mosquito, and the scientists of USDA’s Agricultural Research Service (ARS) are taking aim at this winged attacker with weapons ranging from traditional remedies to computer modeling and satellite images.

While most people have a mental image of research that involves scientists in lab coats, bubbling test tubes and beakers, and technical language that can seem complex, much of the groundbreaking research conducted by USDA scientists actually ends up on your plate, in your home, or on your back. Their discoveries in the lab truly translate into science you can see.

For example, many of us make a conscious effort to eat healthier and cut calories, but it can be tough when faced with a favorite snack, like French fries. USDA scientists have figured out a way to make French fries healthier. Before frying, scientists exposed potato strips to a few minutes of infrared heat. This forms a crispy outer shell on the outside of the fries, which helps to reduce their oil uptake and ultimately reduces calories per serving. If adopted commercially, this method is great news for both food processors and our waistlines.
