"The locavore approach might do a very good job of explaining how regions naturally predisposed to produce a diverse local food supply can do so. It says very little, however, about how we might export from these areas to water stressed regions that cannot provide their own food without extensive importations of water. It says very little, in other words, about trade."And if you're not talking about trade, you're not talking about sustainability:
- James McWilliams, "Just Food"
"Food is fast becoming a national security issue as growth in the world harvest slows and as falling water tables and rising temperatures hint at future shortages. More than 100 countries import part of the wheat they consume. Some 40 import rice. While some countries are only marginally dependent on imports, others could not survive without them.With the result:
Just six countries -- the United States, Canada, France, Australia, Argentina, and Thailand -- supply 90% of grain exports. The United States alone controls close to half of world grain exports, a larger share than Saudi Arabia does of oil."
- Iran and Egypt rely on imports for 40% of their grain supply.
- For Algeria, Japan, South Korea, and Taiwan, among others, it is 70% or more.
- For Israel and Yemen, over 90%.
- Lester Brown, "Plan B"
"Countries under absolute water scarcity will have to import a substantial proportion of their cereal consumption, while those unable to finance these imports will be threatened by famine and malnutrition."
