Abstract
El trabajo de investigación se llevó a cabo en el Área de Conservación Privada Cerro Blanco, ubicada en el cantón Otavalo provincia de Imbabura, cerca de las instalaciones de la empresa UNACEM, la cual produce millones de sacos de cemento al año. El objetivo fue evaluar el porcentaje de absorción de 𝐶𝑂2 de las especies Weinmannia fagaroides y Alnus acuminata en respuesta a los efectos del cambio climático y al aumento de la concentración de gases de efecto invernadero en la atmósfera debido a actividades antropogénicas, buscando determinar cuál de estas especies tiene una mayor capacidad de captura de carbono en su estructura vegetal; este estudio proporcionó información relevante para el proyecto '1 Millón de Árboles' impulsado por la PUCE y la política de Carbono Cero implementada por empresas en todo el mundo. Como parte de la metodología se establecieron dos parcelas para cada especie en sitios seleccionados después de una inspección preliminar del área de estudio, se designaron árboles plus en cada parcela y se tomaron muestras de la copa de los árboles. Se utilizó el método de calcinación para determinar el porcentaje de carbono absorbido por cada especie a través del análisis de cenizas. Además, se estimó la cantidad de 𝐶𝑂2 que se almacenará en el área durante las próximas décadas mediante un método no destructivo, basado en la medición de variables como la altura y el DAP de los árboles dentro de las parcelas. Los resultados indicaron que la especie Alnus acuminata almacena 0,22 toneladas de carbono en su estructura en comparación con la especie Weinmannia fagaroides, que secuestra un valor de 0,10 toneladas en cada uno de sus individuos, por lo que la especie Alnus acuminata mostró una mayor absorción de 𝐶𝑂2 por individuo en comparación con Weinmannia fagaroides.
The research work was carried out in the Cerro Blanco” Private Conservation Area, located in the Otavalo canton of Imbabura province, near the facilities of the UNACEM company, which produces millions of cement bags a year, which are distributed throughout the country. The objective was to evaluate the carbon absorption percentage of the Weinmannia fagaroides and Alnus acuminata species in response to the effects of climate change and the increased concentration of greenhouse gases in the atmosphere due to anthropogenic activities, seeking to determine which of these species has the highest carbon capture capacity in their plant structure; this study provided relevant information for the Million Trees project and the Zero Carbon policy implemented by companies worldwide. As part of the methodology, two plots were established for each species at selected sites after a preliminary inspection of the study area, plus trees were designated on each plot and samples were taken from the tree bowl. The calcination method was used to determine the percentage of carbon absorbed by each species through ash analysis. In addition, the amount of 𝐶𝑂2 that will be stored in the area over the next few decades was estimated using a non-destructive method, based on the measurement of variables such as the height and DAP of trees within the plots. The findings indicated that the Alnus acuminata species stores 0.22 tons of carbon in its structure compared to Weinmannia fagaroides, which sequesters a value of 0.10 tons per individual. Thus, the Alnus acuminata species exhibited higher 𝐶𝑂2 absorption per individual compared to Weinmannia fagaroides.
