Whether visiting Napa or making my way across California’s central valley, I see more and more solar panels and wind turbines on the Golden State’s farms and ranches. And that’s not surprising to me since California has been leading the way towards energy independence and renewable energy production and use.

Remember the good old days when you only got the “spring sniffles” for a few weeks as the new leaves began sprouting on the trees?  And doesn’t it seem like now, for some reason, you’re taking your antihistamine almost as often as you take your multi-vitamin?  That’s not your imagination; that’s climate change at work.

A USDA scientist and his collaborators have proven that ragweed pollen in some parts of the northern United States and Canada now hangs around almost a month longer than it did as recently as 1995.  The researchers’ results show those increases are correlated to seasonal warming shifts linked to climate change dynamics in the higher latitudes.

Rural America is often portrayed in Hollywood as an idyllic place where kids can run free, ride their bikes and pick fresh food out of gardens. The reality is that rural communities face challenges that are different than those experienced in urban areas – especially challenges that contribute to rising childhood obesity levels among rural youth. Despite a perception of abundant resources, including land for growing food and active recreation, rural children face a lack of access to and availability of fresh and nutritious foods, and the distances between destinations makes it difficult to walk or bike and participate in structured and unstructured physical activity programs.

Japanese beetles are tough hombres in the bug world, ripping and chomping their way through more than 300 plant species and nearly 80 plant families.  Farmers and ornamental plant growers spend more than $450 million annually on control measures and replacements for plants destroyed by the beetle, which is by far the most destructive pest of ornamental and turf plants in the eastern United States.

It’s an all-too-familiar truism: Americans don’t eat enough fruits and vegetables. Last week, USDA unveiled the 2010 Dietary Guidelines for Americans, and among the key recommendations was to increase the intake and variety of fruits and vegetables.  A practical tip in the new Guidelines is to fill half of each plate of food with fruits and/or vegetables.

This year’s weather has presented some challenges for Florida’s citrus growers. In December, sub-freezing temperatures hit the citrus-growing region in the state, threatening this year’s citrus crops, which account for more than half of all citrus production in the United States.

1935:  It was the year when baseball legend Babe Ruth hung up his spikes, and New Deal programs like the Works Progress Administration and the Civilian Conservation Corps extended a helping hand to a nation devastated by the Dust Bowl and gripped by the Great Depression.

The National Agricultural Statistics Service (NASS) proudly serves as the statistical arm of the U.S. Department of Agriculture. What some may not realize is that NASS provides statistical information in a variety of formats beyond the traditional paper report, which dates back more than a century.

Just yesterday, NASS launched a new geospatial data service called CropScape. Operated by my team in NASS’s Research and Development Division, CropScape significantly eases users’ access to agricultural geospatial satellite products. By applying the best practices in science and technology, this service links space and agriculture.

For nearly 60 years, a relentless Asian insect with a silly-sounding name--the hemlock woolly adelgid, or HWA--has chomped a deadly swath through 17 northeastern states, portions of Canada and the Appalachian Mountains, literally sucking the life out of native hemlock trees.

If there is one thing you can count on during the holidays, it is food – and in large quantities! While you may not be able to avoid the endless stream of Christmas treats, our eating habits the rest of the year are really important. Especially those we teach our children.
