Estructura de las ventas informales por parte de los vendedores del espacio público del centro histórico de la ciudad de Manizales en el año 2017

In this work, the composition of the informal trade that takes place in the public space of the Historic Center of the city of Manizales, Colombia during the month of December 2017 was reviewed. The exercise was mainly descriptive with the intention of showing only patterns, trends and commercial activity structures; For this, different techniques were applied, such as participatory observation, interviewing, the construction of social networks and synergies through egocentric networks, a reconstruction of the sound landscape and noise levels by sonometric indicators and the cartographic and geostatistical representation of the pedestrian movement and vehicular, in addition some kinematic techniques were used to represent the global dynamics of commerce depending on the urban environment of the place. The results show a series of facts that apparently determine the location and dynamism of informal commerce on the structure of the urban landscape that have to do with structural problems of the city in social and labor material, but also with the configuration of synergies of the activity and centrality conditions that determine the greater flows, speeds, tensions and relationships of the center as a structuring core of the city.
