Check out this video by Dr. Evan Fraser for University of Guelph. He is helping to launch the campaign Feeding Nine Billion.
The purpose of this project and video is to explore how scientific advances, local food, better distribution, regulation and proactive policy can and should play a role in feeding the nine billion people who will soon call this planet home.
He makes some great points about the role local farms can play in buffering against fluctuations in the global markets.
