| Abstract: | The mangroves in Egypt are halophytic trees growing in the upper part of the intertidal zone on the Red Sea shores, lagoons, and on coasts sheltered. The current study was able to determine that suitable environmental conditions that necessary to support mangrove silviculture and restoration. In the current study, we used the Verified Carbon Standard (VCS) as a greenhouse gas (GHG) crediting program to calculate the long-term expected average of carbon stock for potential mangrove (Avicennia marina) silviculture and restoration for (10, 30, 40, and 50 years to harvest cycle of carbon stock) and we estimated the expected average of soil organic carbon (SOC), and carbon sequestration (tCo2/ha) for 10 years of A. marina mangrove silviculture. The results showed that the expected average of total carbon sequestration (tCo2) per hectare recorded 1261.11, 23497.66, and 59214.21 tCo2/ha for 10, 30, and 50 years respectively. Moreover, the estimate of net GHG emission reductions or removals (tCO2e) for the potential mangrove silviculture and restoration activities recorded 3407.42 and 316583.63 tCO2e for 10 and 50 years respectively. Additionally, the expected average total of soil organic carbon (SOC) was recorded at 121.7 t/ha after 10 years of mangrove silviculture. In the current study, since the results of restoration activities may vary within the environmental condition and management regime, an assessment of the efficiency of restoration activities in different scenarios is necessary. Thus, our focus should be extended from developing the regulatory framework of carbon accounting to improving management and policy in mangrove restoration as forest carbon stock enhancement. This holistic effort would increase the benefit of mangrove ecosystem services for communities. |
