vertical farming for feeding the world of the 21st century

By the year 2050, nearly 80% of the earth's population will reside in urban centers. Applying the most conservative estimates to current demographic trends, the human population will increase by about 3 billion people during the interim. An estimated 109 hectares of new land (about 20% more land than is represented by the country of Brazil) will be needed to grow enough food to feed them, if traditional farming practices continue as they are practiced today. At present, throughout the world, over 80% of the land that is suitable for raising crops is in use (sources: FAO and NASA). Historically, some 15% of that has been laid waste by poor management practices. What can be done to avoid this impending disaster? the solution is a very nice idea worth spreading.... I would like to have a TED Talk on this...

  • Apr 17 2011: Hi , I am alway amazed at how people do not know how far advanced Hydroponic growing is In 1998 I was put forward for Farm of the year for growing Cherry Tomatoes Hydroponically without Pesticides or any herbicides and using Biological control. Read here http://verticalgrowing.co.uk/default.aspx
    I have grown crops inside a building commercally and also used Vertical growing. Before people say it someday could be done remember it more than likely has been done. Commercial growers are growing crops Vertically in glasshouses and sealed Buildings and have been for years.

    We are not talking skyscrapers or fancy designs we are talking designs that work on a crop production basis.

      • Apr 18 2011: Hi Lindsay have you looked at my web-site www.verticalgrowing .co.uk
        I have now added that I was Farm of the year awards for 1998/9 for sustainable growing.
        We used |Biological control for pest and we used no chemicals or spraysWe also introduced assured produce which meant that if a customer bought our produce from ASDA we could tell them which green house it came out of and even who picked it. We produced 5 tons of Cherry tomatoes each week and we could colour and size grade 2,500 tomatoes each minute.
