The Bronx Wants a 200,000 Square Foot Rooftop Farm

The Bronx Wants a 200,000 Square Foot Rooftop Farm | green streets | Scoop.it
The City is looking for private developers to install the biggest rooftop farm in the country on a warehouse.

If the City gets its way, the Bronx will soon be home to one of the biggest rooftop farms in the world: It will cover an astounding 200,000 square feet. That's 4.6 acres. The spot is an active warehouse in Hunts Point, an enormous food distribution center where 115 private wholesalers sell food that reaches 23 million people in the metropolitan area.

The New York Economic Development Corporation is working on a general renovation of the area, and issued a Request for Proposals to develop and operate a year-round working rooftop farm...

It's great to see the City getting behind a large-scale project that will complement the growing network of community gardens around the five boroughs. If it comes together, New Yorkers could give up the idea of spending a summer day by a fancy rooftop pool for some urban farming with a view of the river.

Former Malt Factory in Berlin to Become Aquaponic Rooftop Farm

Former Malt Factory in Berlin to Become Aquaponic Rooftop Farm | green streets | Scoop.it

The concept of urban agriculture is fast taking root in our cities, and while images of towering vertical farms with high-altitude pastures and verdant exteriors may captivate us with their fantastical designs, the greatest leaps and bounds in this area stem from simple, tried and true farming methods and adaptive reuse of pre-existing structures. The latest “farm of the future” on the horizon: the Frisch vom Dach, or the Fresh from the Roof project in Berlin. Der Spiegel recently reported on the efforts of three German entrepreneurs to transform the expansive rooftop of a former malt factory in Berlin into a sustainable urban farm projected to produce tons of vegetables and fish for the city each month.

Green Roofs in Big Cities Bring Relief From Above

Green Roofs in Big Cities Bring Relief From Above | green streets | Scoop.it
Turning the black tar roofs that cover our cities into green spaces is not cheap or easy, but its benefits to the environment would be great.

It’s spring — time to plant your roof. Roofs, like coffee, used to be black tar. Now both have gone gourmet: for roofs, the choices are white, green, blue and solar-panel black.

All are green in one sense. In different ways, each helps to solve serious environmental problems. One issue is air pollution, which needs no introduction.The second is the urban heat island. Because cities have lots of dark surfaces that absorb heat and relatively little green cover, they tend to be hotter than surrounding areas — the average summer temperature in New York City is more than 7 degrees hotter than in the Westchester suburbs. 

The other problem is storm water runoff. In New York, as in about a fifth of American cities, there is only one sewer system to conduct both rainwater and wastewater. About every other rainfall in New York, sewers flood and back up, discharging their mix of rainwater and wastewater into the city’s waterways, which could be alleviated by the addition of vegetated roof systems to absorb rainwater...
