Urban Areas Associated to Population Growth and Transformations Produced by Migration.Case Study: Santiago De Cali, Colombia

The urban areas of Colombian cities in recent decades have undergone profound
changes due to the effects associated with accelerated demographic growth due to
particular social and economic determinants. Informality and illegality have
negatively characterized the consolidation and urban development of the country's
main cities, triggering processes that become more complex as a result of the
accumulation of problems and their increase given the lack of timely actions.
Consolidation routines and urban development have been territorialized, becoming
physical-spatial in terms of urban patterns. This way, the territorial transformation
processes can be visualized and understood. From these relationships and placing
the use and nature of the surfaces as a basis. By understanding the city as a sum of
territories with spatial characteristics (physical, social and economic determinants
among others, and in the Colombian case where communes are defined by administrative management), aspects (such as area, population, density urban) can be
contrasted to demarcate the specific scenarios that describe urban development. The
municipality of Santiago de Cali and its communes are hereby studied.
