Presumptive Democratic presidential nominee Hillary Clinton was in Springfield, Ill., Wednesday where she sought to use the symbolism of a historic landmark to draw parallels to a present-day America that is in need of repairing deepening racial and cultural divides.

The Old State Capitol — where Abraham Lincoln delivered his famous "A house divided" speech in 1858 warning against the ills of slavery and where Barack Obama launched his presidential bid in 2007 — served as the backdrop for Clinton as she spoke of how "America's long struggle with race is far from finished."

When we meet the heroin dealer called Bone, he has just shot up. He has a lot to say anyway. He tells us about his career--it pretty much tracks the evolution of drug use in America these past ten years or so. He tells us about his rough past. And he tells us about how he died a week ago. He overdosed on his own supply and his friend took his body to the emergency room, then left.

New British Prime Minister Theresa May announced six members of her Cabinet Wednesday.

Amid a sweeping crackdown on dissent in Egypt, security forces have forcibly disappeared hundreds of people since the beginning of 2015, according to a new report from Amnesty International.

It's an "unprecedented spike," the group says, with an average of three or four people disappeared every day.

The Republican Party, as it prepares for its convention next week has checked off item No. 1 on its housekeeping list — drafting a party platform. The document reflects the conservative views of its authors, many of whom are party activists. So don't look for any concessions to changing views among the broader public on key social issues.

Many public figures who took to Twitter and Facebook following the murder of five police officers in Dallas have faced public blowback and, in some cases, found their employers less than forgiving about inflammatory and sometimes hateful online comments.

As Venezuela unravels — with shortages of food and medicine, as well as runaway inflation — President Nicolas Maduro is increasingly unpopular. But he's still holding onto power.

"The truth in Venezuela is there is real hunger. We are hungry," says a man who has invited me into his house in the northwestern city of Maracaibo, but doesn't want his name used for fear of reprisals by the government.

The wiry man paces angrily as he speaks. It wasn't always this way, he says, showing how loose his pants are now.

Ask a typical teenage girl about the latest slang and girl crushes and you might get answers like "spilling the tea" and Taylor Swift. But at the Girl Up Leadership Summit in Washington, D.C., the answers were "intersectional feminism" — the idea that there's no one-size-fits-all definition of feminism — and U.N. climate chief Christiana Figueres.

Rooftop Farming Is Getting Off The Ground

Sep 25, 2013
Originally published on September 27, 2013 3:03 pm

From vacant lots to vertical "pinkhouses," urban farmers are scouring cities for spaces to grow food. But their options vary widely from place to place.

While farmers in post-industrial cities like Detroit and Cleveland are claiming unused land for cultivation, in New York and Chicago, land comes at a high premium. That's why farmers there are increasingly eyeing spaces that they might not have to wrestle from developers: rooftops that are already green.

The green-roof movement has slowly been gaining momentum in recent years, and some cities have made them central to their sustainability plans. The city of Chicago, for instance, boasts that 359 roofs are now partially or fully covered with vegetation, which provides all kinds of environmental benefits — from reducing the buildings' energy costs to cleaning the air to mitigating the urban heat island effect.

Late this summer, Chicago turned a green roof into its first major rooftop farm. At 20,000 square feet, it's the largest soil-based rooftop farm in the Midwest, according to the Chicago Botanic Garden, which maintains the farm through its Windy City Harvest program.

"We took a space that was already a productive green roof, and we said, 'Why not take that one step further and grow vegetables on it?' " says Angie Mason, director of the Chicago Botanic Garden's urban agriculture programs. That required adding lots of soil amendment, or nutrients, to the rocky medium already up there.

The farm sits atop McCormick Place, the largest convention center in North America, and the goal is for it to supply the center's food service company, SAVOR... Chicago, with between 8,000 to 12,000 pounds of food a year — more than 10,000 servings. It sounds like a lot, but SAVOR serves about 3 million people a year at McCormick Place.

In the first season, Mason says the Windy City Harvest farmers, which include underemployed ex-offenders, will be growing kale, collards, carrots, radishes, peppers, beans, beets, cherry tomatoes and various herbs at the McCormick Place farm. The project's coordinators chose these crops because they're well-suited to a rooftop setting and they're fast-growing.

Over the next few years, Mason says, the plan is to expand the farm to other sections of the McCormick Center roof for a total of 3 acres of cultivation. That would make it the biggest rooftop farm in the U.S., bigger than Brooklyn Grange, which operates a farm of 2.5 acres, or 108,000 square feet, on two roofs in New York City.

Joe Nasr, with the Centre for Studies in Food Security at Ryerson University in Toronto, says projects like these are part of a larger trend toward expanding food production in cities.

"Rooftops will be part of the mix of urban spaces that will be increasingly used to 'scale up' urban agriculture," Nasr told The Salt in an email.

And roof farms in particular can offer a wide array of perks to the building owners.

"When it is feasible to do so, you would be adding benefits to whatever the green roof [already] provides: food, space for community gathering and teaching in many cases, increased biodiversity (depending on the roof) and care for the roof — many green roofs fail because they are out of sight, out of mind, thus neglected," Nasr says.

So why don't we see more of these rooftop urban farms?

According to Mason, urban farmers are just beginning to figure out how to make them work. And they're learning that not every green roof is well-suited for farming.

"You're looking at liability and insurance risk of having people on a rooftop, and then you've got to make sure it's structurally sound enough to withstand the extra soil weight for production," says Mason. "And you've got to make sure that you're training people so that they aren't compromising the rooftop membrane" and damaging it.

Nasr agrees that there are many obstacles to transforming more green roofs into farms: from permitting, to delivering soil and water to the roof, to dealing with growing conditions that are typical of roofs (sun, wind, snow).

But for urban farmers who can find a roof and building owners who will get on board, the potential benefits are worth pursuing, he says. And Mason says she sees plenty of opportunity in Chicago to convert more green roofs into farms — and plenty of building owners interested in burnishing their green credentials.

Of course, you don't have to go as big as a farm to take advantage of the space and sunlight on a roof to grow food. People have been container-gardening on roofs for a long time, and as we reported, this form of micro-gardening is taking off.
