We had an interesting discussion in my Food Ethics course today. Part of it turned to vertical farming and whether such agricultural techniques could be used as an alternative to contemporary agriculture and whether such farming could adequately feed the world.
Here's an interesting article about vertical farming that appeared in the NY Times. The author, Dickson Despommier, is a professor of public policy at Columbia who also has a book on the topic. He contends that vertical farming is a viable source of a tremendous amount of food, especially in urban areas. It seems (from a brief perusal of his book) that vertical farming isn't as input-intensive as we had said in class. In fact, he claims that it's a highly efficient way to farm. If readers of this blog have other resources related to this issue--especially those critical of vertical farming--please let me know.
