There is one nice flash overview showing some components of integrated rooftop strategies, such as wind turbines, rainwater harvesting, composting, greenhouses, and solar panels, with some brief description of each.

A nice element on the blog side, was some photos of Eli Zabar's rooftop greenhouses in NYC, which are renowned for being one of the best productive roofs in the country. From Sky Rooftop: "...Eli Zabar deserves the revenues and the bragging rights; he provides organic produce that is fresher and more local than perhaps any grocery store in New York. I was surprised to find out that Zabar’s actually operates two rooftop greenhouses. In addition to the rooftop of his grocery store, The Vinegar Factory, he has a rooftop greenhouse on his warehouse across the street. The greenhouses grow a variety of fruits, vegetables and herbs. This includes raspberries, strawberries, a variety of greens and herbs, tomatoes, peppers and even dates. A big kudos to Eli for his vision and progressive thinking, proving fresh produce from the roof can be sold commercially and for a profit."

Another interesting side trip led me to Dr. Job Ebenezer, who is the innovator behind the 'wading pool' garden - featured on local project here in Portland at the Rocket. Ebenezer experimented with Wading pools atop the Evangelical Lutheran Church in downtown Chicago as a model for urban agriculture. And this was 15 years ago... so this stuff ain't new. Ebenezer also discusses gardening with feed sacks, and used tires... you name it. This rooftop pioneer doesn't show up on any of the latest articles on urban rooftop ag...

From Container Gardens: "Dr. Ebenezer set about to prove the feasibility of growing vegetables in plastic wading pools. The demonstration garden has proved to be highly successful. In 1997, gardeners harvested 984 pounds of vegetables from 38 pools in an area measuring 1,625 square feet. One pool alone yielded an average of 22.5 pounds of tomatoes, cucumbers, bell peppers, zucchini and a variety of greens. This is equivalent to about 26,800 pounds. per acre, which far exceeds that of commercial yields in the state of Wisconsin and even the national 1996 average yields."
Another pic showing Ebenezer in situ, who focuses this work on technology transfer for feeding the poor through a non-profit group... All this, somehow makes the Rocket, just a little bit less cool... :)
