Mounting Challenges for the World's Food Supply

With an expanding and increasingly urban, meat consuming world population, how will farming co-exist with climate change and water/energy/land scarcity?

Agriculture already consumes 70% of the world's water supply.  And by 2030, farmers will need 45% more water to feed the almost 9 billion people on the planet by then.  Where will it come from? 

Meanwhile, food production, and getting food to the consumer, both use vast amounts of energy.  And traditional energy sources aren't getting cheaper.  These inputs, and more volatile weather, are resulting in large fluctuations in food prices.  And as the author points out, this has often been associated with social unrest.

As a society, how will we deal with this issue?

There is much food for thought in the attached article from Environmental Leader.  Well worth a read.
