How African scientists are improving cassava to help feed the world

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.

Wolves in western America were once hunted to near-extinction but have now been reintroduced into certain territories with notable success. More wolves often means more attacks on ranchers' livestock, however, so cowboys are working to track wolf packs by computer to reduce conflicts.

Clean water and healthy ecosystems are becoming increasingly difficult to come by. With floating islands and other inventions, eco-entrepreneur Bruce Kania thinks that biomimicry - such as reconstructing wetlands and growing biofilms - can tackle the toughest of water problems.

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.

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.

Many different people are inventing health devices for resource-poor settings, but some organizations - like M.I.T.’s Little Devices group - are empowering developing communities and increasing access to healthcare by building medical devices that nurses and doctors in very poor settings can adapt themselves — or kits for making their own, often harvesting parts from toys to cleverly rig up medical equipment. It’s part of a major idea shift, one that’s transforming the design of foreign aid.

Despite significant increases in funding and advances in biomedical research, the rates of new treatments and drugs for illnesses that reach the market every year have plummeted. A group called the Myelin Repair Foundation, along with several other foundations, uses an intensely goal-directed and collaborative method to tackle the bottleneck.

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.

In Australia, the Murray-Darling Basin Ministerial Council was formed after a severe drought to bring together federal, state and regional governments and bridge parochial concerns. It was meant to manage the basin as a whole and end overuse and salinization of farm land, leveraging new technologies to adapt to new realities.
