Mexico 2006 is the 4th World Water Forum held in Mexico City March 16-22, 2006. The theme is "Local Actions for a Global Challenge" which means a focus on making water decisions at the lowest competent authoritative level and as close to the citizens as possible. This is termed "the deployment of the subsidiarity principle."
In the field of water policy, the subsidiarity principle refers to the notion that decisions and actions upon each specific water issue or problematic should take place at the lowest competent authoritative level and as close to the citizens as possible.
'“Local actions for a global challenge,” will be addressed through five framework themes: water for growth and development; implementing integrated water resources management (IWRM); water supply and sanitation for all; water management for food and the environment; and risk management.'
