INCORPORATION OF THE ASSESSMENT OF ECOSYSTEM SERVICES (CARBON CAPTURE AND POTENTIAL INPUT OF NITROGEN) AS PART OF EFFICIENT LAND USE PLANNING

Abstract

The socio-ecosystemic approach within management and planning strategies considers the dynamics both at the different scales of ecological organization and in the relationships and interactions between ecological and social systems. There is a close relationship between C and N cycling due to its accumulation in soil organic matter. The objective of this work is to spatialize the environmental effects of agricultural activities on the dynamics of these elements through the evaluation of suitability for coffee, soybean, and traditional corn crops, using remote sensing techniques and spatial modeling. The estimation of carbon content was based on the calculation of the amount of carbon in the aerial, subway, and soil plant biomass, in order to subsequently make the balance by estimating the tons of CO2 equivalent captured per hectare of the crops compared to the existing cover. Identifying the areas where there may be a greater amount of carbon stored or lost due to emissions compared to the current cover. On the other hand, the potential nitrogen uptake evaluated for soybean was determined from the blue NDVI, which corresponds to an indicator of the concentration of nitrogen in plants, and the difference between the total blue NDVI value of the current cover and the NDVI for the soybean crop was made, in order to identify the impact of the crop on the nitrogen potential of the current cover. From this modeling, the carbon and nitrogen suitability mapping were obtained.
