Carbon sequestration potential of Sago (Metroxylon sagu Rottb.) plantation in Aklan State University, Banga, Aklan, Philippines
Abstract
Global climate change is a widespread and growing concern that has to extensive discussion and negotiations. Thus, this study was conducted to evaluate the carbon sequestration potential of sago plantation. In this study, the simple random sampling was carried out to collect the biophysical data of Sago. The samples were taken randomly of which each sample is given a chance of being selected. The site was measured by the use of meter tape. The area was sub-divided into six quadrats, and it was labeled from Q1 to Q6 of which, each sample quadrats has a dimension of 20m x 38m. Two growth stages of Sago such as rosette and flowering stages were surveyed through destructive sampling and the soil organic carbon was determined through soil sampling. The result showed stages, both the frond and leaves with 0.06kg/plant for rosette and truck/bole with 168.9kg/plant at flowering stage has the highest carbon content stored. Moreover, the total average carbon content at the rosette stage was 0.16kg or 35.68kg/ha. Furthermore, rosette stage has a carbon content of 0.04 t/ha and 23.29 t/ha for the flowering stage. The results showed that older the age of sago the more carbon being sequestered. Soil organic carbon showed that there were 11.6 t/ha stocked in the soil within the area. The total aboveground and belowground carbon is estimated to be 34.93 t/ha. Thus, Sago plantation contains a substantial amount of carbon and plantation endeavor is essential mitigation and adaption measure for climate change.
