Eco-engineering of coastal environment through saltmarsh restoration towards climate change impact mitigation and community adaptation in Bangladesh

Abstract A field research was undertaken to investigate the effects of saltmarsh restoration and some eco-engineering activities on the climate change impact mitigation and community adaptation in the coastal environment of Sonadia Island, Cox’s Bazar, Bangladesh. Two research sites viz., saltmarsh restoration site (SMRS) and impacted site (IP) were selected for this study. Amount of carbon assimilation by saltmarsh plant Porteresia coarctata at SMRS was increased from 165.17 ± 68.35 to 198.18 ± 41.32 g/m2 during the study. The highest carbon assimilation (198.18 ± 41.32 g/m2) was noticed during winter, while the highest biomass (10.47 ± 0.25 kg/m2) was measured from SMRS. Soil compactness, organic matter, organic carbon, field water capacity, plant height, plant biomass and shoot density were found to be significantly (p
