Estimación del costo social del carbono emitido por cambio de cobertura a partir de sensores remotos en la reserva bosque oriental de Bogotá

Abstract

Through this research the estimation of the social cost of carbon due to loss of coverage in the Bosque Oriental de Bogotá Reserve, which has typical coverage of low montane rainforest, biome that has been highly intervened by man due to the expansion of cities, the rise of the limit of agriculture, mining, grazing and burning, which has caused these forests to be increasingly scarce in the Colombian Andes; This represents an important loss at the structural, functional and diversity levels, as these ecosystems are regulators of different natural processes. Given the nature of the inputs, the present study has a work scale of 1: 100,000; the methodology was divided into four phases: in Phase I it is proposed to calculate the various vegetation indexes by means of the most recent satellite image, with which the allometric equations correlated with the biomass found by means of field methodology will be constructed later (phase II) , following the recommendations of the methodology established in the national protocol for the estimation of biomass / carbon proposed by the Institute of Hydrology, Metereology and Environmental Studies - IDEAM in 2011. Phase II was developed in order to calculate the biomass, establishing 28 square plots to take data from individuals with more than 10 cm of DBH (plots of 0.0625 ha) and individuals with DBH between 2 and 10 cm (0.0100). he has). The purpose of Phase III is to generate the biomass equation based on the NDVI (selected vegetation index), this is done by constructing an allometric equation that relates the information by plot of the biomass with each of the indices and finally in the Phase IV through the processing of the images of the other periods, the amount of biomass and carbon is estimated to calculate the social cost of the carbon of each one and be able to compare it with the previous years; and, in this way, estimate the social cost of carbon throughout this period of time in the Bosque Oriental de Bogotá Reserve.
