Contingency planning: Trade's role in sustainable world food security

The cereal and oilseed trade is a necessary contingency for assuring world food security as we restore ecological health to the planet. In a more populous and resource stressed world, trade's role will grow guiding producers and consumers in their choices and facilitating optimal use of natural resources. Greater water efficiency will be a fundamental part of this. The right policies, farm entrepreneurship, conscientious use of land and other resources, knowledge and infrastructure also are required.
