The wetland systems, characterized by transition between terrestrial and aquatic systems; which also include shallow reservoirs; are important in a number of ways to human and environment. Such systems are known for providing ecological services such as supporting higher biodiversity, nutrient cycling, sediment retention, flood control, combating drought, supply of water, regulating microclimate etc. Nevertheless, there is another dimension for appraisal of such systems i.e. their carbon sequestration potential and their role in mitigation of Climate Change. The study was carried out to assess the spatial distribution of Organic Carbon (OC) stock in the sediments and total carbon stored per unit area of Timbi Reservoir. The study revealed that the OC stored in the sediments was 76.2tons/hectare (sediment depth 15cm) with a total OC stock of 3.33x103 tons equivalent to 12.21x103tons of atmospheric CO2. The study also indicated that the part of the wetland inundated for longer period of times stored more OC. This, in fact, is an important result as depleting water levels and exposed sediments may release the stored OC back into the atmosphere. The climate change and depleting wetland and other lentic systems may trigger a positive feedback accelerating climate change.
