Poopspotting: How AI and satellites can detect illegal manure spreading in Wisconsin

Laws in Texas and New Mexico, both locked in the grip of a crippling drought, don't do much to actually encourage citizens to conserve water. New conservation laws and financial incentives are trying to change that.

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.

Amidst a world struggling with smart ways to confront climate change, Hawaii's 2050 Plan for sustainability is working to be a model for the rest of the world. So far, it is on it's way to being a leader in solar energy, with Honolulu having the most "solar panels per capita than any other North American city," and the state is working to produce more food locally, as well.

The lack of access to healthy food has always been a problem for the financially unstable. Food stamps can now be used to buy fresh produce at farmers markets, but greater success could be achieved by getting grocery stores involved.

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.

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.

Although Nigeria "is arguably the worst-run of the world’s major countries," it's biggest city is providing a model for how to turn poor governance around.

In counties that use the “24/7 Sobriety,” they’ve seen a 12% decrease in repeat drunken-driving arrests.

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.

After a devastating cyclone changed the nature of local soil, NGOs preserved Indian rice crops by reintroducing traditional rice varieties that can be cultivated even in salt-ridden earth.
