Mussel Farming Is Healing the UK's Coastal Food Chain

The Green Revolution in Asia and Latin America never spread to Africa, due to the continent's varied climate, degraded soil and lack of infrastructure. Now, scientists look to develop a high grossing wheat seed to bring a new green revolution to Africa. The seeds are extremely promising, but there are still some challenges to getting farmers to implement the seeds.

Officials in Niger are addressing chronic severe droughts causing food shortages and leading to a widespread threat of starvation. They provide aid to malnourished children and resources for a crop planting technique called 're-greening,' which aims to reforest agricultural regions, restore soil quality and, in turn, increase food supply.

Farmers in Vietnam face rising sea levels but rejected the city's water engineering projects. They prefer gradual measures to cope with climate change so scientists have allowed the farmers to steer the conversation.

Louisiana and Vietnam both need affordable solutions to rising sea levels. Leaders from Vietnam visited Louisiana to compare ideas.

Geography and climate change challenge the viability of sea-level cities in Vietnam, but architects, researchers, and urban planners work together to find creative solutions. One architect in Ho Chi Minh City designed green roofs to absorb the rainwater that causes floods.

The World Conservation Union estimates that 40 percent of the more than 40,000 species it tracks on its Red List are close to extinction and this problem requires humans to change their behavior to fix it. Rare’s the Pride Campaign uses social marketing to attract attention and communicate the conservation message between local communities and government entities. The Pride Campaign has been replicated around the world for different conservation efforts to protect biodiversity.

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.

Warming water has led to the collapse of coral reef systems in the western Indian Ocean, essential to fisheries, protecting shorelines, and reducing beach erosion and sea-level rise. Marine scientists from Nature Seychelles, as part of an international project to protect and restore the reefs, are promoting varieties of coral that they have found to be resistant to the rise in temperature.

Through creative financing and new technology, a non-profit in San Francisco is making farmers markets more accessible to residents who rely on federal nutrition benefits.

America is the world’s main supplier of food aid to impoverished countries; however, food aid has the problems of long-distance transportation, the cost of the transportation and storage, and the navigation through dangerous zones. Different programs around the world are experimenting with alternative forms of aid, including vouchers and cash for work.
