Global food security, already threatened by food demand outstripping supply and rising prices, faces greater threats in the future because of projected climate change and climate variability. A coordinated international effort is needed to make relevant technology and information available at the local level in regions that are most likely to be severely impacted. This symposium addresses three critical topics: first, assessing the problem, the relationship between climate change and food security, and specific food security issues that must be addressed; second, adaptation strategies, including the use of grass-roots producer networks, facilitated by modern communications technology; and, third, the role of the international scientific community in both the creation of relevant knowledge and the coordination of technology transfer. The presentations will be followed by a panel discussion with questions posed by a moderator in advance of the symposium. The panelists will be asked to respond with reference to the information presented by the speakers. Questions then will be taken from the audience. The primary objective of this symposium will be developing strong recommendations for action. A post-meeting summary document will be prepared highlighting those recommendations.
