Unforeseen Dangers in a Global Food System

Michael Puma considers what can happen when events such as long-lasting droughts or volcanic explosions interrupt production of these crops. He has begun to assess the fragility of the intricate network of trade relationships that move important basic food items across national borders.

Is there a better way to anticipate climate’s effect on food production?
