Carbon Sequestration in mangrove sediments as Climate Change Mitigation Tool: A Case Study from the Red Sea, Egypt
Blue carbon ecosystems such as mangroves consider a significant carbon pool through their ability to store carbon dioxide from the atmosphere in their sediments and biomass for long periods. Two areas along the Red Sea coast of Egypt were selected for this study (Wadi El Gemal and Hamata areas). The aim of the present study is to understand the capacity of mangroves to store carbon through these objectives: (1) quantify carbon sequestration potential (CSP), (2) detect the mangrove areas change using Geographic Information System (GIS). Results indicated that all mangrove short cores showed an increasing trend of SOC content with depth. The (SOC) contents reach the maximum value at deeper layers with an average of 7.59 ±6.13 g Corg kg-1. The estimated capacity of the carbon pools in mangrove sediments in the Wadi El Gemal area was 5.39 ±0.59 kg Corg m-2 while in the Hamata area, it was 2.25 ±0.19 kg Corg m-2. The mean carbon sequestration rate (CSR) in mangrove sediments in the Wadi El Gemal area was 81.87 ±7.1 g Corg m-2 yr-1 while in the Hamata area was 34.24 ±2.9 g Corg m-2 yr-1. Mangroves in Egypt can mitigate CO2 emissions with a value ranging from 0.0478 to 0.1145 Mt ha-1, equivalent to the total carbon price that fluctuated from 0.9168 to 2.195 MUS$. The total area of mangroves in the study area showed an increase in the area from 56810 m2 in 2001 to 64710 m2 in 2021. The mangrove extent area’s net gain reached 7900 m2 from 2001 to 2021 due to plantation projects. Protecting and managing mangrove areas offer enormous economic benefits for carbon stock and mitigation of climate change.
