Edible Estates is an ongoing initiative to create a series of regional prototype gardens that replace domestic front lawns, and other unused spaces in front of homes, with places for families to grow their own food. The sixteen gardens have been established in cities across the world. Adventurous residents in each town have offered their front yards as working prototypes for their region. �

• Where: Manhatten Warehouse Rooftop • What: Vegetables, greens, herbs and flowers grown. Chickens and bees kept. • Size: 6,000 square feet. On the shoreline of the East River and with a sweeping view of the Manhattan skyline, Eagle Street Rooftop Farm is a green roof organic vegetable farm.

•  Where: London underground bomb shelter •  What: Fresh salad and herbs grown. •  Size: 2x 430m long tunnels

Zero Carbon Food is a commercial venture that utilizes underground redundant space in order to produce leafy greens, herbs and micro-greens. Grown using LED lights and a hydroponics system.

• Where: Hong Kong, 15th floor of a skyscaper • What: Vertical Fish farm • Size: 10,000 square feet OceanEthix International Holdings Limited in New Territories district sells two tonnes of fish to wholesalers each week. Also selling the technology of their 100% water recycling aquaculture system.

• Where: Germany, at the International Building Exhibition • What: Algae powered building • Size: 839 square meters Natural, efficient and unique: the BIQ is setting new standards as the first building in the world to have a bioreactor façade. Microalgae are cultivated in the glass elements that make up its “bio skin”. These are used to produce energy, and can also control light and provide shade.

Algae Biofuel Facade

Water Quality: Shellfish and seaweed act as filters, drawing out nitrogen. While an important nutrient for humans, excess nitrogen from agricultural runoff is creating ever-expanding dead zones in our coastal waters. Kelp and oysters need nitrogen to grow, so act to restore water quality. Then, after we've soaked up the nitrogen, we turn our kelp into liquid fertilizer for local organic farmers. Biofuel: We’re working with a team of scientists and engineers to grow kelp biofuel. On our farm alone it’s possible to grow up to 2000 gallons of biofuel per acre. Restoring Habitat: The lines and cages function as artificial reefs, attracting over 150 species that come to hide, eat and thrive. Food Production: �

A no-soil, vertical garden that grows everything from Swiss Chard to green beans inside O’Hare Airport. Some of O'Hare's restaurants are serving the garden's veggies to customers. O'Hare's veggies are growing inside 11-foot-high plastic towers. The roots are suspended in the air and fed a nutrient-rich water that trickles down through the towers and then gets recycled.�

Crickets Or Cultured Beef Anyone? 5 Proteins Of The Future As global demand for meat increases, it’s clear that future protein production will require incredible innovation. Our global population is set to reach 9 billion by 2050, and both demand for meat and meat prices are expected to double concurrently. Today, nearly 1/5 of all greenhouse gases come from industrial livestock production and roughly two thousand gallons of water go into a single pound of industrial beef. But a new study from Oxford University found that lab-grown meat would require just one percent of the land and four percent of the water of traditional livestock production.

Tiny Farms

some of our thoughts How to scale up urban agriculture to meet the challenge.

Online Community Food Network Online food market connecting local consumers with local growers. Allows orders to be placed for produce as well as next year planting requests.

Infrastructure Farm Taking public space for food
