Determinación de concentración de CO2 en suelos del distrito regional de manejo integrado (DRMI)-Paramo Rabanal jurisdicción de Corpochivor, como base para implementar acciones de mitigación y adaptación al cambio climático.

Abstract

In the Regional District of Integrated Management (DRMI)-Páramo Rabanal, located in the municipality of Ventaquemada in the department of Boyacá; with an extension of 6,640 hectares; This project was developed, which aimed to determine the concentration of CO2; for which a sampling was made at different points of the three areas where the land use problem exists, which are: protected area area, area area dedicated to livestock (dairy cattle) and the area dedicated to agriculture (potato crop, Solanum tuberosum) ; Subsequently, the organic carbon analysis was carried out by the Walkley-Black method with quantification by colorimetry, using a UV spectrophotometer; the apparent density was also determined using the metal ring kit, as data for the diagnosis of soil retention capacity; based on the maps delivered by the Geographic Information System (GIS), the deficiency of CO2 capture of the soil was found depending on the problem of each area; to establish strategies that contribute to the care and preservation of the páramo ecosystem, since it has a great potential for CO2 capture; with which the reduction of greenhouse gases, which are associated with climate change, is sought. According to the above, the area devoted to agriculture is the one that is capturing the least CO2, being only 652,229.91 ton/ha while the area dedicated to livestock retains 1,672,825.21 ton/ha, which is more than the half that of the agricultural zone; fact that is due to a large extent to the compaction generated by the trampling of the animals, in this case dairy.
