How three U.S. mini-farms are sowing the seeds of global food security

It’s no secret that, although progress has been made, school lunches need help to become more nutritious and sustainable. School officials in San Francisco are partnering with researchers from UC Berkeley's School of Public Health to better school lunch programs and, ultimately, curb child obesity.

Concerned with colony collapse syndrome in honey bees worldwide, scientists, farmers and tech companies teamed up in Australia to create a micro-sensor that collects data on the bee's environment.

Half of U.S. farm workers are Hispanic, but few make it to leadership positions. A historically white non-profit, FFA, is creating equal education programs in California to increase leadership opportunities for minorities in agriculture.

To decrease the nation's food waste, activists in Denmark showed the people that it was safe to buy and consume items that were very recently expired. From live demonstrations where celebrity chef features expired items in the entrees to reducing prices for out-of-date items, "Danes now throw away 25 percent less food than they did five years ago."

Organizations in Detroit are piloting a program to apply food stamp credits in grocery stores towards the purchase of nutritious produce, in order to increase access to healthy items. The initiative can also help the local economy prosper through increased promotion of locally grown produce.

In an agricultural system designed for big-industrial growers, many farmers struggle to bridge the relationship between their produce and consumers, as well as strengthening local economies. The food hub is a collection of buildings that process and distribute the sale of local food. Eastern Market in Detroit is an example of a food hub that makes local produce accessible to low-income neighborhoods.

Culinary and agricultural education can sometimes take a backseat to the more academic side of high school. But Blue Hill is teaching high school students the importance of healthy cooking and home grown produce through a cooking class that was recently instituted in Manhattan high schools.

Soil in Bangladesh is becoming increasingly saline and infertile due to climate change. Bangladeshi farmers have begun using a saline-tolerant rice seed in order to produce an abundant crop despite salty soil.

In India, many farmers, especially women farmers, have transitioned to organic farming. While it requires a serious set of skills and knowledge, organic farming increases yields and decreases costs by eliminating the need to buy pesticides. The move is both ecological and economical, and the Indian government is trying to spread the solution.

The System of Root Intensification (SRI) method resulted in dramatically high yields from one Indian village. The system centers on a "less is more" approach and results in higher yields—without the use of GMOs. The idea has faced barriers in spreading, as scientists are wary of it, even as villagers embrace the empirically successful approach.
