URBAN FRESH ISLANDS CHARACTERIZATION IN THE CITY OF CALI, COLOMBIA

Abstract

In order to achieve sustainable cities, it is important to include within urban planning processes, the benefits provided by biophysical elements such as vegetation. Therefore, this research aims to conduct a characterization of what is here defined as Urban Fresh Islands -IFU- in the city of Santiago de Cali based on the presence of vegetation and its relationship with temperature. In addition to this, it was taken into account the perception and assessment made by the community about these spaces and their spatial distribution in the territory. Remote sensing techniques were an important tool for the development of the research. To identify the IFU areas, indicators such as NDVI and NDWI were collected and used in conjunction with Land Surface Temperature (LST) and built up area (NDBI) ฀฀฀฀฀฀฀฀฀฀ and 2011 Additional information was gathered by means of direct observation, surveys and qualitative research techniques in order to assess the perception and valuation of vegetation-temperature relationship in certain areas of the city.
