Sustainability Of Least Cost Policies For Meeting Mexico City's Future Water Demand, Timothy Downs, Marisa Mazari-Hiriart, Ramón Domínguez-Mora, Irwin Suffet
Sustainability and Social Justice
Meeting future water demand without degrading ecosystems is one important indicator of sustainable development. Using simulations, we showed that compared to existing policy, more sustainable water supply options are similar or cheaper in cost. We probabilistically forecasted the Mexico City metropolitan zone population for the year 2015 to be 23.5 million and total required water supply to be 106 m3 s-1. We optimized existing and potential supply sources from aquifers, surface water, treatment/reuse, and efficiency/demand management by cost to meet future supply needs; the applied source supply limits determined the degree of sustainability. In two scenarios to supply 106 m3 …

The dispersion of persistent, bioaccumulative toxic chemicals poses risks to human health and the integrity of the ecosystem on a continental scale. Mexico, the United States, and Canada sought to add two pollutants to an existing list of four subject to North American Regional Action Plans (chlordane, DDT, mercury, PCBs). Mexican negotiators used results from an internal selection process, applying 14 criteria in five categories - physicochemical, health-endpoint, data quality/quantity, exposure potential, and control feasibility - to a baseline group of over 4,700 substances. Using policy analysis by the multi-attribute maximum-utility method; progressive application of criteria and weighting algorithms acted …
