On October 16, World Food Day, it is hard to not be struck by how lucky we are in the United States. We have abundant food that costs us less to produce, on a per unit basis, than almost any other country in the world. Our farmers and ranchers produce more than we need, allowing us to be a powerhouse in global exports. And our food supply is among the safest of all the world’s nations.

All that abundance and security has been underpinned by science and know-how.  Between the 1940s and the 1970s, agriculture science blossomed in what has become known as the Green Revolution. Thanks to the research done by Norman Borlaug, the “Father of the Green Revolution,” working with researchers around the world, developed high-yielding varieties and modern production practices that helped save untold numbers of people from starvation.

Organic agriculture is proving itself to be a veritable cornucopia, according to the results of the first-ever report on certified USDA organic production, which we released earlier this month. While the number of organic farms is a fraction of its conventional counterpart, an organically produced version of virtually every crop or animal product is now available in the United States.

This was the first time the National Agricultural Statistics Service (NASS) conducted this survey, which means that we cannot see trends yet, but we can already easily see some of the impacts of organic production in the United States. From four farms in Alabama, Alaska or Delaware to 1,898 farms in California, every state in the nation is now home to USDA-certified organic producers. And while these farmers make up less than a half of one percent of all U.S. farmers, they already sell more than $3.5 billion worth of agricultural products.

It’s shaping up to be a good year for students in Indian Country.

For the first time in school history, students at Saginaw Chippewa Tribal College in Mount Pleasant, Michigan can register to take physics thanks to an upgraded laboratory. And at Leech Lake Tribal College in Cass Lake, Minnesota, students were able to take trigonometry for the first time last year.  Funded and supported by USDA’s National Institute of Food and Agriculture (NIFA ), both schools made  improvements to bolster their students’ learning in the areas of science and mathematics.

NIFA’s Tribal Colleges Education Equity Grant is a noncompetitive program that enhances educational opportunities for American Indians in the food and agricultural sciences.  These grants strengthen formal educational opportunities at the associate, baccalaureate, or graduate level at 1994 land-grant institutions, also known as tribal colleges.

Even back in the days of Mark Twain’s riveting tales of steamboat pilots and derring-do on the Mississippi River, it was known that you could catch a crook by means of almost invisible clues left at the scene of the crime:  the unique patterns of his fingertips.  How do we know this? In Twain’s “Life on the Mississippi,” published in 1883, a murderer was identified by his fingerprints.

Farmers are the ultimate survivors.  By definition, their work requires incredible planning, but it also requires creativity. This year, farmers have faced the test of limited summer rains, which have lowered the productivity of many farmers’ yields.  With fall approaching, farmers have an opportunity to invest today for better outcomes next year by planting what are called “cover crops.” Not harvested like a main crop, cover crops are mowed to stay on top of the soil or disked in for soil improvements.

Cover crops offer a wide range of benefits: they “trap” nitrogen left behind by fertilizer in the field, which otherwise may be washed away over the winter. They conserve water, improve the quality of soil, suppress weeds, and control insect pests and erosion.  Cover crops can also provide an excellent source of animal feed during periods when drought has reduced forage.

USDA science counts conservation research as an important area, so our scientists continually study cover crops, including timely focus on the impacts of drought stress to reduce potential losses in U.S. production capacity.  Using a grant provided by USDA’s National Institute of Food and Agriculture, researchers at Purdue University show that cover crops left on the soil surface after germination in spring will conserve soil moisture acting as a soil cover. This can increase crop yields in dry years and reduce year-to-year variability in yields.

For many military veterans and their families, the transition from the military to civilian life is a complex undertaking; however, reports and personal accounts indicate that many military veterans have discovered that farming offers a place for employment, training and healing.  The problem is there are few educational programs tailored to meet the particular needs and abilities of returning veterans.

The National Institute of Food and Agriculture’s (NIFA) Beginning Farmer and Rancher Development Program (BFRDP) makes it possible to fill that gap in training.  At the University of Arkansas, Dr. Dan Donoghue used BFRDP funds to develop internships, workshops and online courses that focus on the needs of veterans interested in pursuing farming after their service to our country.

Words like eco-friendly, green, fair, climate-friendly, community-based and organic are popping up daily – in the news, in ads and labels, and in conversations ranging from kitchen tables to international conferences.  All of these and more come under the umbrella of sustainability, which people often describe as caring for people, planet and proceeds all at the same time.

When Leech Lake Band of Ojibwe water resource professionals discovered that 60 percent of the Minnesota reservation’s septic systems were sub-standard or failing, they feared for the reservation’s health, indigenous rice fields, and fish populations.

Shirley Nordrum, a Leech Lake Extension educator with the University of Minnesota, responded with an extensive education program.   She explains to homeowners how having the sanitation department pump their septic systems could protect their health and contribute to the safety of the environment and their community.  She uses funds from U.S. Department of Agriculture’s (USDA) Federal Recognized Tribes Extension Program (FRTEP) to conduct this outreach effort.  Her program has become a model for other communities.

Today, President Obama and I continue doing all we can to help farmers and ranchers impacted by the drought. As Congress comes back to Washington in September we will continue to encourage passage of a Food, Farm and Jobs Bill as soon as possible – to give USDA tools to help those who have been impacted by drought, while giving more certainty for farmers and ranchers.

While the drought has taken a toll on agriculture this year, we also know that America’s history of agricultural innovation and research advancement means farmers and ranchers are better-prepared than ever before to mitigate its effects.

USDA scientists and research partners have helped to provide these important new tools for decades – and their work continues today.

When it comes to microorganisms that contaminate our foods, you may think it’s a veritable jungle out there—but in fact, in the United States, most of the illnesses, hospitalizations and deaths caused by foodborne pathogens come down to 14 bad players.
