I have a Global Environmental Challenges class at the University of Ottawa, and we are currently focusing on population dynamics and the strain it is causing on the earth. It got me thinking… what may need to occur, or what would `save` the world if you will, is another agricultural revolution. With the whole `green movement` as of late, there has been a tremendous focus on innovation in Real Estate development. What is missing (in my opinion), is architectural innovation with respect to agricultural land development – building UP instead of OUT for example. I know there are already people working on these types of ideas – I have seen a picture or two. My question is… what do you think will happen to the value of agricultural land if (or maybe WHEN) there is another agricultural revolution, and new and innovative development is ALLOWED on agricultural land?
Is this something that you think could ever happen?
Global trends would have me believe that such an event may happen out of necessity (main driver of innovation), and when it does – the currently low valued AG land may skyrocket.

Not only is it fresh and free of pesticide, it uses space that is otherwise wasted and helps reduce your carbon footprint!
