Evaluation of the effectiveness of biomechanical practices of watershed management on carbon sequestration for climate change mitigation, case study: Kouhdasht aquifer management and Romeshkan flood spreading

Global warming is affected by greenhouse gas emissions such as carbon dioxide, metan, nitroxid by industrial and agricultural activities. This study was aimed to evaluate the watershed biomechanical effects on modification of climate change in the Romeshkan flood spreading station and Kouhdasht aquifer. For this purpose, four tree species of Eucalyptus, Cypress, Almond and Fig in the Romeshkan flood spreading station and five tree species of Pistachio, Pomegranate, Fig, Cedar and Almond in Kouhdasht aquifer were chosen adjacent to mechanical structures, all planted in 1996. Then, ten samples¬ were taken with two replications from different parts of each tree by full cut of these species and Carbon sequestration of each part was computed by different experimental procedures. According to the results from the study sites, the condition of carbon sequestration by Eucalyptus was better than other species with an average of 167/9 ton per hectare. Results showed that Eucalyptus and Cypress trees planted in Romeshkan flood spreading station and Fig and Cedar trees planted in Kuhdasht aquifer had the greatest amount of carbon sequestration in their branches. Also, Almonds, Pistachios and Pomegranates planted in Kouhdasht aquifer had the greatest amount of carbon sequestration in their roots and Figs planted in Romeshkan flood spreading station had the greatest amount of carbon sequestration in their stems, and Almonds planted in the Kuhdasht aquifer had the greatest amount of carbon sequestration in their roots and branches. Also, studies showed that the leaves of all species had the minimal role in carbon sequestration.
