1 Towards a fully integrated urban weather environment climate service in Mexico City Mexico City Ministry of Environment SEDEMA Tanya Müller (Secretary of Environment), Beatriz Cárdenas (SEDEMA), Luisa T. Molina (MIT/MCE2) Cities & Climate Change Science Conference WMO Session Guide for Integrated Urban Weather, Environment and Climate Services March 6, 2018 Edmonton, Alberta, Canada

2 MEXICO CITY: TOPOGRAPHY URBAN EXPANSION Mexico City Metropolitan Area Megalopolis Urban Area 2000 Urban Area 2010 Built on the dried bed of elevated Lake Texcoco and its surrounding High altitude: 2240 m; strong sun insolation Surrounded three sides by mountains and volcanoes- physical barrier for winds Temperature inversions in dry season

3 MEXICO CITY METROPOLITAN AREA 21 million inhabitants split between Mexico City and part of the State of Mexico. High population density and intense industrial and commercial activities. Mexico City Emissions Inventory, 2014

4 MEXICO CITY CHALLENGES Multiple risks due to geographic location and socio-economic context made worse by Climate change Social and spatial inequality & high vulnerability to climate change Integrated long-term planning and regional coordination in the Megalopolis (comprising Mexico City and 5 surrounding states with separate juridictions)

5 MEXICO CITY MAIN RISKS Climate change has become the biggest long-term threat to Mexico City s future. it is linked to water, health, air pollution, traffic disruption from floods, and housing vulnerability to landslides EXTREM Mexico City Resilient Program, 2017

6 MEXICO CITY IUWECS Motivation for integrated services: To provide key information to different sectors of Mexico City population about weather, water, air quality, climate, wildfires Most of these originated to the needs for providing timely information to both decision makers and citizens due to the problems Mexico City has faced over time, including air quality management originated due to the bad air quality Mexico City monitored in late 1980 s; water services due to the flooding Mexico City suffer during rainy season; wildfires that occurred every hot season in Mexico City protected land area; volcanic hazards from volcanic eruption and emissions These services are provided by Mexico City Government through the different agencies that report to the Mayor and to the public.

7 MEXICO CITY IUWECS Air quality data and AQ forecast Seismic system MULTI-HAZARD MONITORING Volcanic alert Hydrometeorological alert system Vector-borne diseases related to climate change Wildfires

8 O 3, Max, vol SUCCESSFUL AIR QUALITY MANAGEMENT ACTIONS Air quality and GHG policy and management Collaboration with government agencies, especially Health Agency Monitoring air quality Scientific Committee for Environmental Improvement

9 CDMX CLIMATE ACTION PROGRAM (PACCM) 4.36 million tons CO2eq reduced by April % of progress towards 2018 goal

10 CDMX RESILIENCE STRATEGY Adaptive, inclusive and equitable transformation 100 CIUDADES RESILIENTES Collaboration with Rockefeller Foundation through 100 Resilient Cities 5 Pillars Launched in Sept 2016

11 MULTI-HAZARD MONITORING SYSTEM CENTRE FOR COMMAND, CONTROL, COMPUTATION, COMMUNICATIONS AND CITIZEN CONTACT (C5) Goal: Response within 5 minutes of an incident Resources: 1 main centre (C5) 5 regional centres (C2) 2 mobile command and control centres Telephone centre for emergencies (#911) 8,088 cameras

12 COMMUNICATION TO THE PUBLIC Air Quality Monitoring Network Forecasting

13 COMMUNICATION TO THE PUBLIC Hydrometeorological Bulletin Risk Atlas

14 CDMX CHALLENGES IN ADDRESSING INTEGRATED SERVICES Continue and finalized integration among Mexico City agencies Collaborate and integrate with other systems (i.e., Federal systems) Continuity through administrations Continue to promote more collaboration with national and international institutions and private sectors even during hard economic times Expand and strengthen capacity building for technicians and scientists Send messages: improve communication with citizens Use information to evaluate and improve the system

15 GOOD PRACTICES AND LESSONS LEARNED Research has been very important for designing, implementing and improving many of these services: Mexico City has a long history of collaboration with research institutions, both national and international, including National Autonomous University, National Politecnic Institute, Harvard University, Barcelona Supercomputing Center, Molina Center for Energy and the Environment, among others. Mexico City Ministry for Science and Technology has also devoted budget to support many research studies related to these services. Open data, transparency, and innovation as part of Mexico City public policy Investment in new technology: measurements, transmission and publications Human resources as one of the key priorities Science as the basis for informed decision making Continuity through different administrations
