Evaluation and economic value of Hedera colchica in urban land management

Abstract

Carbon sequestration is the process of capturing, securing and storing carbon dioxide from the atmosphere. In this study, the carbon sequestration capacity of Hedera colchica was investigated in soil of a semiarid region in Iran. Samples were taken from plants cultivated in the semiarid area of the polluted metropolis of Tehran and the amount of sequestered carbon in the aboveground and underground parts of the plant was measured. The conversion coefficient of carbon sequestration of plant organs (stem, leaf, and root) was determined separately by the combustion method. Carbon tax policy was used to evaluate the carbon sequestration function, as the shadow price of carbon. The results showed a significant difference in the amount of carbon sequestration in different organs of the plant. Stems and roots with 29.3 and 4.3 t ha−1, respectively, showed the highest and lowest amount of carbon deposition. The results of the economic value showed that the carbon shadow price was $40567.6 ha−1 on average. In general, the results of this study showed that the organs of H. colchica can have a beneficial effect in the process of carbon sequestration.
