Identifying federal research dollars for ag

A new book chapter by American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America highlights critical agricultural research areas receiving federal funding, including biofuel production, environmental quality, food safety, and nutrition. The chapter highlights $429 million increase in NIFA's compe...

Bringing the world of agriculture to the classroom

A new approach to teaching agriculture in the classroom uses case studies to motivate students and inspire changes in attitude. The study found that engaging students with real-world examples improved their understanding and presentation skills, but some felt that more time was needed for discussions and activities.

Small family farms in tropics can feed the hungry and preserve biodiversity

Researchers Ivette Perfecto and John Vandermeer argue that small family farms in tropical regions can provide a better way to meet both food production and biodiversity preservation goals. They propose an alternative model, the matrix quality model, which enables plants and animals to migrate between remaining forest fragments.

USDA grant to create healthy urban food enterprise development center in Arkansas

The Healthy Urban Food Enterprise Development (HUFED) Center will provide training and technical assistance for small and mid-sized agricultural producers, aiming to increase access to healthy, affordable foods in low-income areas. The center is designed to promote positive economic activities generated from attracting healthy food ent...

Stable climate and plant domestication linked

A new study argues that a stable climate, rather than climate change, played a crucial role in the emergence of agriculture in the Near East. The research suggests that farming communities chose crops that functioned within the normal east Mediterranean rainfall pattern, allowing for sustainable farming practices during drought years.

Asia faces food shortage by 2050 without water reform

The region may need to import over a quarter of its rice, wheat and maize if current irrigation management is not improved or innovated. A new study warns that Asia's vast irrigation systems must be revitalized to meet the growing food demand without further straining water resources.

Study finds human population expanded during late Stone Age

A study found that human populations began to expand in size in Africa around 40,000 years ago, supporting the hypothesis that population growth played a significant role in the evolution of human cultures. The research used genetic evidence and computational approaches to simulate the evolution of genetic lineages over time.
