Estimación del potencial de secuestro de carbono en suelos forestales de la provincia de Jaén

Abstract

La respiración del suelo (Rs) —flujo de dióxido de carbono (CO2) emitido desde la superficie del suelo hacia la atmósfera— es un indicador clave del funcionamiento de los ecosistemas terrestres. En este trabajo se estimó y comparó la emisión de carbono en tres suelos forestales de la provincia de Jaén — localizados en Bedmar y Garcíez, Huesa y Villarrodrigo— con el objetivo de analizar cómo los factores ambientales y estructurales del ecosistema influyen en Rs. Se seleccionaron tres parcelas por localidad —dos repobladas con Pinus halepensis y una con vegetación natural autóctona—, en las que se midió Rs mensualmente y la humedad y temperatura del suelo de forma continua, estimando posteriormente, mediante un modelo, el flujo de CO2 durante el período de estudio. Los resultados mostraron una mayor Rs del suelo en Villarrodrigo, seguida de Bedmar y Garcíez y, por último, Huesa. Generalmente, las parcelas de vegetación natural emitieron más CO2 que las repobladas, salvo en Huesa. Estos hallazgos indican que ecosistemas más desarrollados y menos alterados presentan mayor Rs, resaltando la importancia de conservar la vegetación natural y considerar las condiciones locales en la gestión forestal.

Soil respiration (SR) —the flux of carbon dioxide (CO2) emitted from the soil surface to the atmosphere—is a key indicator of the functioning of terrestrial ecosystems. In this study, carbon emissions were estimated and compared across three forest soils in the province of Jaén —located in Bedmar y Garcíez, Huesa, and Villarrodrigo— with the aim of analyzing how environmental and structural ecosystem factors influence SR. Three plots were selected in each locality —two of them were reforested with Pinus halepensis and one with native natural vegetation— where monthly SR was measured, and soil moisture and temperature were continuously recorded. Subsequently, a model was used to estimate the CO2 flux throughout the study period. The results showed a higher rate of SR in Villarrodrigo, followed by Bedmar y Garcíez, and finally, Huesa. Generally, plots with natural vegetation emitted more CO2 than the reforested ones, except in Huesa. These findings suggest that more developed and less disturbed ecosystems exhibit higher SR, highlighting the importance of conserving natural vegetation and considering local conditions in forest management.
