According to the information published in the 2010 Living Planet Report, 3,500 million people live in urban areas and estimations say that for the year 2050 this number will duplicate to almost 6,300 million people.
In the case of Mexico, this problem becomes relevant when we see the alarming growth in the conurbation of the country’s main cities:
- Guadalajara City: conurbation with municipalities such as El Salto, Tlajomulco de Zuñiga, Tlaquepaque, Tonalá, and Zapopan.
- Monterrey City: conurbation with municipalities such as Apodaca, García, General Escobedo, Guadalupe, Juárez, Santa Catarina, San Nicolás de los Garza, and San Pedro Garza García.
- Mexico City: has a crushing total amount of 56 municipalities. Those that stand out are due to their impact on the Metropolitan Area: Chimalhuacán, Ecatepec de Morelos, Atizapán de Zaragoza, Tlalnepantla de Baz, Coacalco de Berriozábal, Ixtapaluca, Tultitlán, Cuautitlán Izcalli, Valle de Chalco, Naucálpan de Juárez, and Ciudad Nezahualcóyotl.
Unfortunately, we have not used space wisely and now we must face the consequences, because when we promote horizontal growth in cities, we have created serious environmental problems.
