Crecimiento de la mancha urbana 1950-2015

Title
Crecimiento de la mancha urbana 1950-2015
Abstract

El crecimiento expansivo de la mancha urbana se relaciona con la falta de acceso de la población pobre a una vivienda o a un predio de bajo costo en el interior de la ciudad, y da pie a la existencia de asentamientos humanos irregulares (AHI), dispersos y periféricos, en su mayoría, establecidos en tierras ejidales y comunales
Las mayores concentraciones de AHI se encuentran en las demarcaciones de Xochimilco, Tlalpan y Milpa Alta. Entre los años 2000 y 2015, el territorio ocupado por...
