Worldchanging Executive Editor Alex Steffen has become a respected voice of dissent in the global conversation about geo-engineering strategies. This fall, he re-enters the debate as part of the cast of front-line innovators featured in a new docu-style series from Discovery and Impossible Pictures. The program, called Discovery Project...

Since World War II, Midwestern farmers have been encouraged to use machinery, chemicals and government policies to ramp up crop and livestock production to feed the growing population and economy. But since then, many farmers have felt the harmful effects of this quantity-over-quality production model, and have started to investigate how to make their methods more sustainable. During the past few decades, small organizations promoting sustainable agriculture have been popping up and banding together across the Midwest to create a patchwork of information, support and tools for those interested in taking part in the sustainable agriculture movement. Groups like the Midwest Sustainable Agriculture Working Group and its lobbyist sister group the Sustainable Agriculture Coalition started promoting ideas of sustainable farming in 1988. The coalition is made up of farm...

by John Thackara Every day 1.5 billion cups of coffee are drunk somewhere in the world – quite a few of them in this house - but few of us in the North know much about the 25 million families that grow and produce this valuable bean. After reading a new book called Confronting The Coffee Crisis I feel better informed not just about the negative aspects of the story - but also motivated to explore practically the potential of emerging alternative trade networks to change the bigger picture in profound ways. In a system that can involve as many as eight transactions to bring the coffee to market, coffee farmers receive less than two percent of the price of a cup of coffee sold in a coffee bar or...

By Glenn Fleishman The unsightly plastic warts on our walls are sucking down hundreds of gigawatts of power globally each year. It’s time to put a stop to that needless energy drain by replacing dumb bricks with smart hubs -- putting a computerized stake through the hearts of our home electrical vampires. Devices that are plugged in but not in use consume between 200 and 400 terawatt hours (TWh) per year, according to the International Energy Agency. Other research pegs the not-in-use drain from 5 to 25 percent of all residential energy used in the U.S., with numbers rising. Research doesn’t divvy up between the consumption of DC-converting “wall warts” that provide juice to recharge batteries or convert power for various electronics, and the power sucked by the standby...

San Francisco may have the most technologically nifty new parking system in the U.S., but Chicago wins big points for the mercenary genius of their approach: the city expects to raise over a billion dollars by auctioning a 50-year concession on their entire parking system. Private vendors are willing to pay so much for the right to manage the city's 36,000 parking spaces because they know the real estate is presently underpriced. The winning bidder will be required to install "state-of-the-art parking meters that monitor parking space availability and adjust rates to ensure an open space on every block." The new system should reduce congestion, lower greenhouse gas emissions, improve air quality, and generally make the city more livable. It will also mint a good deal of cash for...
