ANALYSIS OF LAND USE CHANGES AND TERRITORIAL DYNAMICS IN THE LOW BASIN OF THE CHILCA RIVER, PERU

Abstract

The objective of this study was to analyze the territorial dynamics linked to changes in land use in the lower Chilca river basin of the Lima region, from 1975 to 2018. The analysis was performed applying qualitative techniques such as interviews to depth, focus groups and timeline workshops with key informants, then it was contrasted with the results of the corresponding satellite image processing, in a GIS environment, according to the CORINE Land Cover model, European model of land cover. The results of the analysis of those 43 years, came to identify that the industrial and infrastructure and urbanized areas are those that have had a considerable expansion; while the coverage of areas without or with little vegetation and agricultural areas were those that have suffered the greatest reduction. This situation has generated a series of dynamics in the territory of the study area, which is manifested in evident processes of territorialization and de-territorialization of activities and socionatural processes such as the threat to the cultural heritage of Bandurria and the sunken farms, increased employment and social problems, among others. This situation is linked to processes of the growth of cities, in this case of the city of Lima.
