A novel coupled framework for detecting hotspots of methane emission from the vulnerable Indian Sundarban mangrove ecosystem using data-driven models

Methane Emission in Mangrove Forests: Field Study and Environmental Correlations from Xuan Thuy National Park, Vietnam

“…Other than freshwater sites, methane emission (0.02-0.5 mmol m −2 day −1 ) as mentioned by Abril and Borges [20] 0.02-0.5 mmol m −2 day −1 and was comparable to the value reported from the Avicennia mangrove site, Can Gio Mangrove Forest, Hochiminh City, Vietnam [3]. The Xuan Thuy methane emission rate in this study was higher than the values reported from Ranong Biosphere Reserve, Thailand [21], Red Sea, Saudi Arabia [22], Rhizophora mangrove site at Can Gio Mangrove Forest, Hochiminh City, Vietnam [23], but lower than those reported values from the Fitzroy River, Johnstone River, and Burdekin River mangrove creeks, Australia [24]; mangrove forest in Ouemo, New Caledonia [25]; Sundarban mangrove ecosystem, state of West Bengal, India [26], and Dongzhaigang National Nature Reserve, China [27] about 2, 6, 9-20, 12 and 27 fold, respectively (Table 4).…”

“…Land use/ land cover changes are also the driving force of CH 4 generation. The research of Das et al [26] revealed that the highest CH 4 generation area was the mangrovedeforested agricultural lands, while the lowest produced region was the coastal mangrove forested region. This agrees with Zheng et al [35], who reported that, on average, undisturbed mangrove sites have very low CH 4 efflux rates.…”
