“…In this study, peat depth reached up to 900 cm, as all peat samples from the surface until the peat auger could not penetrate anymore were sampled and analyzed to get the overall C-stock estimation of the LSBP ecosystem. In contrast with the study of Decena et al (2022) in the same area, the study only considered the 1 m depth, which could be an underestimation.…”

Leyte Sab-A Basin peatland (LSBP) is the second largest peatland in the Philippines and comprises 3,088 ha (31 km2). The study estimated the C storage and carbon sequestration capacity of the peatland’s four (4) ecotypes, namely, swamp forest (SF), marshland (ML), agroforestry (AF), and agricultural land (AL) using allometric equations. SF rendered the highest downed wood C-stocks followed by AL and AF. For the litter C-stocks, AF rendered the highest, followed by SF, ML, and AL. SF rendered the highest root C-stocks and CO2 sequestered, followed by AL and AF. C% is highest in ML with values ranging from 32-43 C% across the soil peat depth, while SF ranges from 29-34 C%, and AL and AF both with 19-37 C%. The LSBP stores 36.6 Tg of C and 134.5 Tg of CO2 sequestered. This C storage amount can represent 0.04% of tropical peat carbon.

“…Fe and San Miguel, Leyte. Geographically, it is an elongated basin extending from west to east, located near the northern coast of Leyte, with a metamorphic ridge acting as a natural boundary (Decena et al 2022). Covering an approximate total area of 3,099 hectares, a significant portion, about 44% has been reclaimed for agriculture.…”

Peatland restoration is considered one of the most cost-effective ecosystem-based interventions for climate mitigation and adaptation, but also for sustaining local welfare and livelihoods as well as building the climate change resilience in local communities. However, despite its promise, the governance of peatland restoration as an ecosystem-based adaptation strategy poses significant challenges for local communities. Given that problems associated with peatland restoration often involve governance constraints and institutional mismatches, this paper presents an analytical framework illustrating how ecosystem-based adaptation (EbA), through adaptive governance (AG) strategies, can promote for a more comprehensive and flexible practices in response to evolving environmental conditions and stakeholder needs. Located in Leyte Sab-a Basin Peatland, Philippines, this study shows that governance issues posed by peatland restoration problems often originate from a lack of comprehensive sense-making of the intricate nature of these challenges and that responses, therefore, tend to be counterproductive. These results empirically support the need for a workable governance approach capable of facilitating the necessary governance changes to address the complexities of peatland restoration problems adequately.

“…For some individuals with prop roots extending well into the canopy, tree diameter was measured above the stilt roots, where a true main stem exists. Additionally, the height of the tree was visually determined using a 2-m long calibrated pole (Madeira et al 2009, Decena et al 2022). Other non-tree mangroves or mangrove associates were also noted.…”

The paper presents a detailed ecological investigation of mangroves (trees and palm) along Carigara Bay in Leyte, Philippines by comparing the diversity, vegetation structure, species composition, and indicator species among forest types (riverine and fringe) and zones (landward, middleward, and seaward/along water) as well as by examining their relationships with environmental variables. A total of 22 mangrove species, belonging to 12 families were documented wherein the most abundant was Sonneratia alba, followed by Nypa fruticans, then by Avicennia rumphiana. It was found that the diversity (Shannon-Wiener) of riverine mangroves (0.94 ± 0.07; 1.20 ± 0.04) was significantly higher than the fringe for both in the middleward and seaward/along the water. In the fringe mangrove forests, the mangrove species Aegiceras corniculatum was associated with the middleward zone, and Camptostemon philippinensis, Aegiceras floridum, Rhizophora mucronata, Sonneratia alba, and Lumnitzera littorea were associated with the seaward zone, whereas landward zone of fringe and all the zones in riverine were generally associated by species with low to optimum salt tolerances such as Nypa fruticans, and Avicennia rumphiana as the most abundant. As well, a total of 14 mangroves have been identified as indicator species. Lastly, mangrove species can be generally classified as riverine and fringing based on the environmental factors explaining their distributions, and it has been found that soil porosity, water content, soil salinity, and distance from the sea or river’s edge were the most significant environmental factors that determine diversity patterns.
