What a project in Wisconsin can teach others about working with farmers to reduce phosphorus runoff

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.

Most insurance companies avoid insuring poor farmers because the transaction costs are too high, but a non-profit in Kenya created a sustainable way to cover them.

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.

The program makes inmates into taxpayers instead of tax burdens and offers skills that are useful for future employment once they leave prison.

In Colombia, traditional cattle pastures have caused soil degradation, deforestation, and desertification. To reconcile this, several thousand acres of land in Latin America have been transformed into a silvo-pastoral system of grazing and raising cattle with agro-forestry.

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.

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.
