Leadership from Nimroz and Helmand provinces met with members of the United States Agency for International Development and the International Security Assistance Force, March 1, to discuss water management. After the presentations, a demonstration of water flow down the Helmand River basin sparked a lively debate among summit attendees. The demonstration, designed by Dr. Jean Jolicoeur, here, illustrated proper and improper water usage in three games summit attendees played using marbles that rolled down a 3-dimensional representation of the Helmand River valley and its catchments.
