The inference drawn is that aboveground carbon differs within location across the study area, owing to the uneven distribution of rubber plantations, but also at the landscape level, attributable to topographic and edaphic heterogeneity, as well as land-use and natural disturbance background. This finding of AGB is slightly not consistent with [PERSON] et al. [32] and [PERSON]'s [37] above 20 years old para rubber AGB estimates using field procedures in China and Thailand, respectively. However, the findings fall within the range reported by [33], the default value range for Asia continental estimated biomass carbon (78-180 (continental)) tonnes C ha\({}^{-1}\), stated in the 2006 IPCC guidelines for forest biomass [28], and the work of [PERSON], et al., [49], who estimated para rubber AGB using a very high resolution satellite (Thaichote--2 m ) in northeastern Thailand, they reported value range of 66.89 to 228.58 tonnes C ha\({}^{-1}\) for plantations ages of 18 to 25 years old. There may be several reasons for slight inconsistency in results, which conspicuously include differences in model and scale of assessment. It is noteworthy to mention that the biomass of a plantation could be influenced by the planting thickness, cultural practices, and age. Therefore, the inconsistency could in part be explained by this work leveraging on a novel dynamism of remote sensing coupled with the generic model which has the capacity for large-scale estimations, and the fact that the model was based on a large scale with the assumption that all plantations are 25 years old and are the same quality except sizes. Rubber tree plantations are widespread in Southeast Asia and have an impressive carbon storage capacity due to their rapid growth rates [50]. This, combined with optimal climatic conditions and plantation cultural practices such as fertilization and other good management practices adopted by farmers in Songkhla province due to the rubber tree's economic value, could contribute to the area's significant biomass potential. This finding suggests that this region is essentially a net carbon sink. The generic model provides a useful framework for estimating how different pools of the above-ground feedstock can be obtained, and this technique affords a convenient outline comprising a range of biomass fractions. Therefore, important biomass potentials of this study were identified as theoretical biomass, energy usable biomass, and other economic purposes biomass. The theoretical AGB potential here refers to the biological biomass. It is the entire above-ground biomass in the aggregate biomass, since it is possible to express the ratio of biomass to productivity, which could be regarded as the biomass accumulation ratio, hence it reflects carbon concentration in dry biomass. Conversely, the para rubber tree synthesizes biomass in the entire above-ground parts ranging from the wood to seeds which have different quantities of harnessable values with diverse suitability for utilization. Although these were originally designed to suit commercial construction and furniture, the leaves and other wastes generated during harvesting may usefully be applied in soil conditioning and plantation land recuperation among other potential uses. The energy usable biomass potential is the share of the above-ground theoretical feedstock, entailing the part of naturally obtainable biomass that can appreciably be used for energy generation. This may insinuate the para wood and wood products which have the potential for energy generation-related merchandise like fuelwood, pellets, chips, charcoal, sheets, sawdust, and their derivatives. Nowadays, wood-burning has become the leading solid fuel biomass energy source. The applications foreseen are not only in heating systems but also in use to power steam engines and steam turbines to generate electricity. These energy merchandises may be used indoors or outdoors, and are perceived by sundry as an unconventional, viable source of renewable energy, cheaper, cleaner, and more proficient relative to other fuels.
