Using Landsat images for the calculation of the Sustainable Development Goals Indicator 11.3.1: “Ratio of land consumption rate to population growth rate”, in the urban agglomerations of Colombia

Abstract

This article explains the methodology developed by DANE to calculate indicator 11.3.1, defined in the 2030 agenda of the Sustainable Development Goals, which measures the efficiency of land use to make cities inclusive, safe, resilient and sustainable; and presents the results in the application of the urban agglomerations of Colombia. This is a list of satellite images of the Landsat program captured in the years 2003 and 2015, which are classified to obtain the constructed area of the agglomerations in each year, in order to calculate the rate of land consumption. Subsequently, based on the population projections of DANE for these same years, the population growth rate was calculated and, finally, the value of indicator 11.3.1 was obtained from the relationship between the rates for 107 cities.
