In this week's Gizcast, we're privileged to be joined by Dr. Dickson Despommier of New York City, who is perhaps the world's leading expert on Vertical Farming, a topic we've covered several times in the past few years. Dr. Despommier speaks with Loz Blain about the social, economic and environmental issues we'll have to face as the Earth's population jumps to 9 billion in the next 40-50 years. If we keep farming the way we are now, we're simply going to run out of land to feed ourselves - so the solution seems clear: we need to start bringing food production and agriculture into the high-rise age. The farms of the future, it seems, will be skyscrapers. Geoffrey Baird also joins us for a weekly roundup of top stories.
