Vertical farming - The future of growing food?

    Lately I'm reading a lot about vertical farming. Wiki defines it as "a component of urban agriculture" and "the practice of producing food in vertically stacked layers, vertically inclined surfaces and/or integrated in other structures. (such as buildings and skyscrapers)"
    Also this article predicts that the market is estimated to reach USD 3.88 Billion by 2020, which is huge growth for a market that barely exists.

    What do you think about vertical farming? Could it become the trend that would define the future agriculture?

    I'm a big fan of it.

    In a small scale I'm trying to use my window sills to grow some crops like salad and some herbs, and since my garden space is limited, I'm trying to stack plants vertically too.

    On a larger scale I see this as a very promising approach, particularly for distributed and subversive activities like urban gardening. I'm a bit doubtful for the food factory like approaches, but if they work, even the better.

    Columbia University professor Dickson Despommier, , author of "The Vertical Farm" says that vertical farming could be part of agriculture’s future.
    Despommier envisions the world’s food system will increasingly turn to vertical farms to help feed a hungry planet. By the year 2050, the world’s population is expected to be 9.1 billion, up from about 7 billion today. That translates into a 60 percent increase needed in global food production, according to the United Nations. Despommier estimates that the amount of new farmland needed to grow the amount of food needed in 2050 is larger than Brazil. Unfortunately, more than 80 percent of the world’s land that is suitable to grow those crops is already being used.
    That’s where vertical farming comes into play. Despommier defines vertical farming as growing food inside a building that is at least two stories high often with the use of hydroponics (submerging plants’ roots in nutrient-fortified water), aeroponics (spraying roots with a similar solution) and LED technology.
    Now there is an updated version of vertical farming now being explored. In this version of a vertical farm called Skyfarm, all the benefits of vertical farming previously explained are still utilized, but it now incorporates wind power as its source of clean energy thanks to the wind turbine built at the very top of it.
    It provides electricity to the rest of the Skyfarm by utilizing the windmill design.

    Two induction lights are mounted evenly spaced over a 4’x8′ grow area and at the same height as the LEDs. The benet of Illumitex ES2 LED bars is that they can be evenly spaced over the grow area and provide a very uniform coverage without the hot spots that induction or HID create. The height of the LED bars is calculated to deliver proper PPFD to the plant canopy. The wattages of the xtures in the comparison shown are 390 watts for the LEDs and 840 watts for the induction lights. Initial cost of both systems are equivalent; however, total cost is lower for LED because of energy savings. As an added benet, the Illumitex LED lights provide dimming as a standard feature while the induction lights require additional cost for dimming.

    They use LED lights to create a specific light recipe for each plant, giving the greens exactly the spectrum, intensity, and frequency they need for photosynthesis in the most energy-efficient way possible. This engineered lighting allows us to control size, shape, texture, color, flavor, and nutrition with razor-sharp precision and increased productivity.
