The world's largest rooftop urban farm is set to open in Paris next year - and it's already projected to feed thousands of people every year.

The garden, which is being constructed in the southwest region of the French capital, will span over 14,000 square meters (150,700 square feet), making it the largest urban farm in Europe.

Managed by a team of 20 gardeners, the organic sanctuary will grow 30 different plant species.  The representatives say that the site will likely produce about 1,000 kilograms (2,200 pounds) of fruit and vegetables every day in high season.

In addition to hosting a variety of educational workshops and farming classes, the site will also allow local Parisians to lease out tiny segments of the rooftop for their own gardening needs.

The developers say that they are designing the project around a specialized aeroponic 'vertical farming' technique so that the garden will use no pesticides and very little water.

The founder of the development company has a vision of a city in which flat roofs and abandoned surfaces are covered with these new growing systems. The goal is to make this farm a globally-recognized model for sustainable production, using quality products, grown in rhythm with natures cycles.
