We know that antibiotics are those miracle drugs Alexander Fleming stumbled upon in the 1920’s when his lab was left untidy. Since that happy accident, scientists have identified additional naturally-occurring antibiotics and developed synthetic drugs to add to our arsenal to combat bacterial infections.

So we’ve had bacteria, through their need to survive, learning how to develop resistance to naturally occurring antibiotics in the environment for eons; long before we started purposefully adding more antibiotics to the mix. So though we need antibiotics, it would be really nice if we could find ways to rely on them less.

Just like a smart phone helps users learn, communicate and make important decisions, smart technology—known as precision agriculture—helps farmers know and apply critical information about the right investments in fertilizer, seed, pesticide and water needed to produce their crops. Through new technologies, farmers produce more efficiently and see an increase in profits while improving stewardship of ecosystems and local communities.

To talk about precision agriculture is to talk about mapping the amount of a crop grown per acre (yield) or the types of soils in a given area. It also includes the technology that automatically guides farm machines and controls variables like the rates of seeds, fertilizers or chemicals.

July is the height of summer grilling season, and throughout the month USDA is highlighting changes made to the U.S. food safety system over the course of this Administration. For an interactive look at USDA’s work to ensure your food is safe, visit the USDA Results project on Medium.com and read Chapter Seven: Safer Food and Greater Consumer Confidence

Have you ever wondered how to safely grill your burgers? How about determining the latest food safety recalls?  USDA provides a number of resources to ensure that you have access to the most up to date information on food safety.

Keeping the food on America’s tables safe to eat is a serious challenge and USDA is serious about helping families avoid dangerous bacteria and other contaminants that can lead to foodborne illness. The Centers for Disease Control and Prevention estimates that one in six Americans are likely to become ill from foodborne illness each year, but most of these illnesses are thought to be preventable. That’s why USDA provides a number of tools consumers can use in order to prevent or reduce the risk of foodborne illness that would spoil the meal.

In 2050, there will be about 9 billion people in the world. How do you feed 9 billion people? Clearly, we need more food, greater production, and more efficient processes, but how do we achieve that and how does that translate to success?

The answer may be found through science and data.  USDA works hard to provide good data to decision makers on the farm, in the field, at the lab and in the office place. This data includes economic information that characterizes and evaluates global market performance and keeps food and agricultural systems working smoothly.  Information includes data on crop production, farm income, food and agricultural prices, trade, nutrition, and food security.

Responding to Climate Variability is one of the goal areas of the REE Action Plan.  The objective is to develop science-based knowledge to address climate variability, position agricultural communities to reduce emissions of greenhouse gases, and enhance carbon sequestration.

Many valuable USDA accomplishments for the year 2015 were the result of cross-divisional teams that developed useful tools to support decision-makers with research-based data.  Knowing weather and climate patterns--driving forces behind the success or failure of cropping systems--is vital information to land managers.  One such tool, AgroClimate, supported by REE and the National Oceanic and Atmospheric Administration (NOAA), helps users manage climate risk with tools that provide information on crops best suited to grow in their region, based on water availability and the amount of water a crop will use.

Recently, USDA participated in the White House launch of the Federal Crowdsourcing and Citizen Science (CCS) Toolkit. By providing federal employees with information about developing CCS activities, the Toolkit will eventually allow the Federal government to design more programs that ask citizens to help us in solving both simple and complex problems.

Now, USDA is excited to announce our role in helping to harness “the power of the crowd” with the official release of CitizenScience.gov.

Recently, the National Society of Minorities in Agriculture, Natural Resources, and Related Sciences (MANRRS) hosted its 31^st National Career Fair and Training Conference. MANRRS is a non-profit organization that promotes academic and professional advancement by empowering minorities in agriculture, natural resources, and related sciences, and has more than 1,650 members in 38 states.  Welcoming people of all racial and ethnic backgrounds, MANRRS works to increase diversity of talent in the field of agriculture.

As a longstanding partner with this organization, USDA helped sponsor the 2016 MANRRS conference, where over 950 participants from across the Nation gathered to discuss ways to grow the next generation of leaders. Participants ranging from high school students to professional members explored the latest developments in the agriculture, natural resources, and related sciences along with professional development, networking, and mentoring.

Nearly 99% of farms in the United States are family operated, and they account for roughly 90% of agricultural production. With statistics like these, it’s not surprising that many people associate jobs in agriculture with small-town America, farmers and tractors, and corn fields and cattle.

While the importance of farmers cannot be overstated, the diversity of careers available in the agricultural sector is staggering and often underappreciated. According to a 2013 study funded by USDA’s National Institute of Food and Agriculture (NIFA), an average of 57,900 jobs will open every year from 2015 to 2020 and require a bachelor’s degree or higher in food, agriculture, natural resources, or environmental studies. These jobs will include a range of sectors, including management and business; science, technology, engineering, and mathematics (STEM); food and biomaterials production; and education, communication, and government services.  Strikingly, it is also expected that 39% of positions will go unfilled.

We’re all fortunate to live in a country that has one of the most productive and efficient food production systems in the world.  The United States produces over 430 billion pounds of food each year.  However, nearly a third of the food produced by farmers goes uneaten, representing $161.6 billion.  That’s enough food waste to fill 44 Sears Towers every year.  To meet this challenge, USDA scientists are developing innovative programs and using cutting-edge research to reduce food waste on the farm, on supermarket shelves, and in the home.

USDA scientists work 365 days to provide safe and sustainable food, water, and natural resources in the face of a changing climate and uncertain energy sources. To recognize the contribution that agricultural science and research makes in our daily lives, this week’s “Banner Year” series features stories from 2015 that show the successes that USDA science and statistical agencies made for us all.

In 2015, we’ve seen agriculture and natural resources at the crossroads of the world’s most critical problems: establishing sustainable food production, providing clean and abundant water, responding to climatic variability, developing renewable energy, improving human health, and strengthening food safety.  The immensity and diversity of the difficulties Americans face allowed USDA an excellent opportunity to once again demonstrate our ability and capacity to rise and meet the greatest of challenges.

Here are five stories from 2015 to review:
