16 Flooded Communities

17 Aguascalientes Irrigation District #1 57 Mm3/year State Deficit 325 Mm3/year Depletion of Water Table Subsidence Seismic activity Reduction in Aquifer Capacity Obligation to treat water Presence of heavy metals in drinking waters sources Alternative Sources? Alternative City

18 Possible Conflict Points Scarcity and Development Upstream Pollutant Downstream Historic use Political power Absolute volumes in water allocation Political Boundaries do not match Social Boundaries Political Force/Party Duplicity of work o Plan ahead o Negotiate a treaty with your neighbor before someone else does!
