The Vertical Farm Project contains information, designs, and presentations on high-rise type structures for farming located in urban environments. They argue that agriculture will need to shift towards this paradigm in order to handle the food requirements for the level of population we can expect to see in 2050 (i.e., 3 billion more mouths to feed). There are also other factors leading us in this direction. Much of this work is still in the design phase so there may be a first move advantage for those willing to invest in building the first significant prototype designs.
