Abstract
Changes in land use and architectural renovation are a normal process in historic urban centres, and as a consequence there are changes in the occupation of properties, such as the loss of vegetation cover and filtering soils that could be integrated into the urban green system, which is now almost entirely concentrated in the public space. In this study, a series of orthophotographs of the historic centre of the city of Loja were analysed to determine the changes in vegetation cover and its distribution among squares, parks and private properties. The study puts into context the way in which the city has modified the extent of green cover throughout its modern history. An analysis of aerial imagery was carried out using a pixel classification technique to determine the proportion of area per pixel analysed, and maps were produced to study the distribution of urban greenery in the study area and compare its radius of influence in each period studied. The results show how the historic centre is becoming detached from the urban green system, reducing the presence of green cover on private properties and concentrating on the public space of squares and parks in the centre. This study also explores strategies to protect and increase the distribution of green areas, which can contribute to the reduction of environmental problems in the city.
