All over the world, deforestation and forest degradation are under the microscope because together they comprise the second greatest driver of climate change. If you focus on the country of Ghana, you’ll find one of the highest deforestation rates in Africa.

In fact, the country has lost nearly 90 percent of its original forests. The losses are due to a variety of factors including wood extraction and agricultural expansion. The remaining forests are home to forest elephants, Diana monkeys and many types of rare, endemic amphibians—and many rural communities that often struggle to support their families.

Although automation in agriculture is often synonymous with efficiency, that has not been the case with harvesting and processing berries.  That is about to change.

Automated berry processing systems often damage the fruit, which results in lower profitability for growers and marketers.  To counter this, a University of Georgia (UGA)-led research team is developing an advanced sensor system to help harvest and process fresh-market highbush blueberries at high-speed and with low yield loss.

Over the last 25 years, the American farmer has become increasingly aware of the impact of South American agricultural output on the global supply of grains and oilseeds.  For example, in recent years Brazil has risen to the number one position as an exporter of soybeans.  Further, the combined output of Brazil and its neighbors, Argentina and Paraguay, is challenging the United States’ position as the world’s leading supplier of corn.

Brazil is unique in that it has a relatively stable agricultural output trend due to improving production techniques, and in most years, abundant rainfall for production of various crops.  The climate and cropping patterns are behind the increases in agricultural production, which were made possible by the shift of production into regions less prone to drought.  There is also the potential for expansion into untapped lands, although infrastructure and land ownership issues are a limiting factor.  Meantime, thanks to ample rainfall and land resources enjoyed by producers, Brazil has the potential to become an agricultural powerhouse for years to come.

As a law student, I spent a summer working and living with the Sokoagon Band of the Chippewa, a Native American tribe located in rural Northern Wisconsin.  Tribal leaders and members extended to me their kindness, friendship, passion and laughter.  They are some of our country’s finest.

But, make no mistake, the Sokoagon face challenges shared by many persistently poor rural communities across our country.

That summer, I saw with new eyes the importance of dependable and consistent employment, housing, health care systems and education.  That summer I also saw that for many rural Americans these things, taken for granted by many, are luxuries.

A hike through Kentucky’s Red River Gorge is a trip that outdoor enthusiasts never forget. The adventure begins amid rugged terrain with towering sandstone cliffs that contour steep, forested slopes. Visitors discover hundreds of natural stone arches and other unique rock features that create some of the most splendid geological formations east of the Rocky Mountains. Within the beauty and solitude of the gorge resides a rare plant found nowhere else in the world.

The white-haired goldenrod occurs predominantly in the Daniel Boone National Forest, typically found growing along the base of cliffs or on ledges. In areas where the ground is undisturbed, this plant thrives in moist, sandy soil underneath rock shelters. During the fall, the plant blooms with bright yellow flowers along its upper stem. Alternating white-haired leaves line the stem from its base.

No-till farming used to be only about reducing soil erosion. Today, continuous no-till is the preferred tillage system in some areas. Why? It’s all about soil health.

The loss of organic matter in soil, which is the lightest soil component and the first to wash away, is the healthiest portion of our topsoil. It is the house where the biological systems in our soils live and includes everything from the tiniest organisms like bacteria, algae, fungi, and protozoa to the more complex nematodes, micro-arthropods (think tiny spiders), and the more visible earthworms, insects, small vertebrates, and plants. They are all part of healthy soil.

The Healthy, Hunger-Free Kids Act of 2010 celebrated its fifth anniversary last month, and I can tell you it has made a difference!  I think back on the past five years and am proud of the strides we’ve made in giving students access to more local and healthy food in our schools.

Accompanied by FNS Administrator Audrey Rowe, I had a wonderful visit with two Georgia elementary schools this fall. Our trip to Alexander II Magnet School in Bibb County and Westside Elementary School in Houston County highlighted 2015 National School Lunch Week celebrations (October 12-16) and offered a great example of progress on the school meals front.

For agricultural producers, it’s an age-old question: How do you grow the largest, healthiest, most-profitable crops possible? Oregon organic farmer Chris Roehm says the secret is in the soil.

Co-owner and operator of Square Peg Farm in Forest Grove, Roehm is among a growing number of producers, both conventional and organic, who are realizing the benefits of improving the health and function of their soil through working with USDA’s Natural Resources Conservation Service (NRCS).

The USDA Farmers Market, next to the Department’s headquarters and steps from the National Mall in Washington, D.C., is a “living laboratory” for identifying and testing strategies to help support local and regional food systems.

To mark the 20^th anniversary of the market, my colleagues and I at USDA’s Agricultural Marketing Service (AMS), which manages the weekly Friday market, tried a few new approaches during the 2015 season.  Our goals were to make the market more successful for vendors and more enticing to visitors.

For example, we opened the market a month early--in May instead of in June.  We also redesigned the layout of the market, allowing us to more than double the number of vendors from 14 to 32.

An intrepid fossil hunter on the U.S. Forest Service’s Flathead National Forest in northwest Montana doesn’t need to dig too deep to find exquisitely preserved fossil insects with traces of their original stomach contents. Amazing as this sounds you just need to visit rock outcrops of the Kishenehn Formation exposed on the banks of the Flathead River.

There, researchers affiliated with the Smithsonian’s National Museum of Natural History have discovered a treasure trove of tiny, 46-million year old fossil insects from the Eocene Epoch, which were deposited in sediments of an ancient lake early during the Age of Mammals. The preserved insects—over 7,000 specimens have been collected over the last several years—include fossil mosquitos. At least one specimen preserves an abdomen still engorged from its last meal.
