Breadfruit has been a hit in Melanesia, Micronesia and Polynesia for more than 3,000 years because of its many pluses: This tropical staple food crop is plentiful and packed with nutrients. It’s hailed by some as a possible solution to world hunger, but it could play a totally different—but equally important—role in saving lives.
Scientists with USDA’s Agricultural Research Service (ARS) have found that breadfruit flowers contain three chemicals that work wonderfully for repelling flying insects, including mosquitoes. In Hawaii and other regions, people have known for years that burning dried clusters of the flowers, known as “male inflorescences,” can keep bugs at bay. Read more »

Pacific Southwest Regional Forester Randy Moore believes that every child should have the opportunity to go camping, take a hike and explore nature. And with the stroke of a pen, he signed in late September a proclamation endorsing the California Children’s Outdoor Bill of Rights as a group of children gathered to watch.
Moore wanted to publicly show the Pacific Southwest Region’s support for the statewide initiative, which was created to encourage children to experience outdoor activities and promote active, healthy lifestyles.
“You all represent the future,” said Moore to the children huddled around his desk. “It is important for us to have you learn about the outdoors, and we want you to enjoy being outdoors.” Read more »
This fish tank is located in Honolulu, HI at the President William McKinley High School, and illustrates the cleanliness of water in an aquaponics/aquaculture system. For aquaponics, when the system is properly balanced, the water can be maintained at maximum clarity. Photo courtesy of the Hawaii Department of Agriculture.
If you’re wondering what aquaponics is, you’re not alone. Tracing its roots back to the Aztecs and rice cultivation in South China, aquaponics is a combination of aquaculture and hydroponics – growing fish and plants together in a symbiotic system. Basically, the plants keep the water clean for the fish to grow, and the fish fertilize the plants. Both help the other to survive and thrive.
A wide variety of foods—lettuce, beans, broccoli, cucumbers, peas, herbs, strawberries, melons, and tomatoes, for example—all flourish through aquaponics farming. Read more »

2013 is the International Year of Statistics. As part of this global event, every month this year USDA’s National Agricultural Statistics Service will profile careers of individuals who are making significant contributions to improve agricultural statistics in the United States.
Growing up in Texas, you’re never far removed from agriculture. Even though I grew up in Houston, my grandparents had a beef operation and I’ve always believed that agriculture is simply in my blood. I also knew that I had a passion for numbers, so when time came for me to pick a college major, Agricultural Economics seemed like a great combination of my two passions.
I earned my degree from Prairie View A&M University in Texas. During my junior year, I joined USDA’s National Agricultural Statistics Service (NASS) Texas Field Office as an intern, which ended up transforming into a full time position with the agency’s Arkansas office after my graduation.

On a recent cool, crisp spring morning in the mountains of Virginia, the Boy Scouts of America Troop 88 followed in the footsteps of the first “boys” of the Civilian Conservation Corps, the CCC.
The first CCC camp, Camp Roosevelt, was established April 17, 1933 at the George Washington and Jefferson National Forest. Over time, the forest had 14 camps. Read more »

Many teachers use creative methods to keep their students engaged in the curriculum they are teaching. Some methods work far better than others. For one group in Hawaii, teachers are using gardening to boost their science, technology and math classes, while placing an emphasis on Hawaii’s need for more experiential science learning related to agriculture and sustainability.
