This document summarizes the presentations slots and discussions that took place at the Fourth US-Mexico Joint Workshop on Mexico City Air Quality on March online gambling casinos 8-10, 2001. This workshop was organized by the Integrated Program on Urban, Regional and Global Air Pollution: Mexico City Case Study (Mexico City Program), a collaborative research and education program aimed at improving the way pokie machines complex environmental problems are addressed in developing countries. The goal is to develop both the methods and the institutional capacity to balance economic, social and technological factors in order to make appropriate decisions in the face of incomplete data and uncertainty. Mexico City serves as the initial case study for the Program's research and educational activities.

An important component of the Mexico City Program has been the annual workshops on air quality, which provide a forum for project investigators slots games to share their most recent research findings and to build the relationships critical to the Program's success. In addition, the workshops provide a neutral forum to exchange information with the decision makers. This Fourth Workshop was the continuation of work carried out by the Mexico City Program that resulted in recommendations made to the Mexican Government, presented in "Estrategia Integral de Gestión de la Calidad del Aire en el Valle de México." (MIT-IPURGAP Report No. 7, October 2000). The objective of the second phase is to continue the process review and research, and to place more emphasis on evaluation of the strategies with cost and benefit quantification and evaluation of different strategies.

The Fourth Workshop was well attended with about 80 participants from Mexico and 30 from the U.S. and Canada. In addition to Program investigators and representatives from the Federal District and the State of Mexico and the State of Hidalgo, the workshop brought together a number of new partners and observers from several key U.S. agencies, including the Texas Natural Resource Conservation Commission, California Air Resources Board, US EPA, U.S. Embassy, North American Commission for Environmental Cooperation, and Environmental Defense, who are interested in participating in this ongoing effort. This wider representation is welcome since we would like to apply this Program to other regions, especially in the U.S.-Mexico border areas.

We would like to acknowledge El Colegio de Mexico for hosting this workshop, and the MIT/AGS and the Mexican National Institute of Ecology (Instituto Nacional de Ecología, or INE) for co-sponsoring it. As in the past, this workshop would not be possible without the tireless effort of Luisa Molina and the invaluable support of Jose Luis Lezama and his colleagues at El Colegio de Mexico, as well as the support of the U.S.-Mexico Foundation for Science. We would like to thank all of the speakers and moderators of the Plenary Sessions and the facilitators and rapporteurs of the Breakout Sessions who presented thoughtful and engaging talks and discussions at the workshop. Finally, we would like to thank Rebecca Dodder for coordinating the preparation of this report ¾with support from Chiz Aoki, Anas Benbarka, George Darido, Andres Flores, Barclay Gibbs, Michael Gilat, Kelly Roth, Federico San Martini, Samudra Vijay, Jason West and Miriam Zuk¾ and Luisa Molina for editing and typesetting the final report.
