evaluate wetlands as organic carbon reservoirs to address the challenges of climate change
Abstract: The effect of climate change is unequivocal. The projected rise of temperature will impair the ecosystems on Earth and hinder their abilities to function properly. Wetlands are an important unseen carbon sink richer than forest and rangeland per area, their preservation could save the situation. In this study tow forested riverine wetlands, and a mangrove forest wetland, were examined. In summer season, samples were taken, carbon concentration was determined in the soil samples collected. In the winter season samples were taken to compare with the summer season. The carbon turnover times were also measured to know the residence time of carbon in the soil using Accelerator Mass Spectrometry (AMS) i.e. C14 dating. The wetlands’ floors were richer in carbon content than the forests’ floors and the uplands’ floors except in one wetland. Temperature and hydrology were taken as controlling factors. One of the wetlands acted as a source of carbon in the second season due to the unsuccessful flooding event. These findings, based on past studies, were very satisfactory. This study revealed that the hydrology is an important controlling factor as well as the temperature and its pattern has been affected by the climate change.
