“…Although the response of mangrove biomass to HV backscatter is highly correlated, there is saturation above 120-150 Mg·ha −1 [9,39] and in some cases, a dense canopy with very high (>200 Mg·ha −1 ) biomass can in fact decrease backscatter [23]. However, with average biomass at 93.7 ± 33.0 Mg·ha −1 [55], it can be assumed most of the Sundarbans will not exceed saturation for sensitivity to biomass. Uncertainty in the results can arise from variations in the gain and response sensitivity of the instrument, however, the radiometric calibration for backscatter makes any difference negligible [56].…”

Abstract:Mangroves are an important bulkhead against climate change: they afford protection for coastal areas from tidal waves and cyclones, and are among the most carbon-rich forests in the tropics. As such, protection of mangroves is an urgent priority. This work provides some new information on patterns of degradation in the Sundarbans, the largest contiguous mangrove forest in the world, which are home to more than 35 reptile species, 120 commercial fish species, 300 bird species and 32 mammal species. Using radar imagery, we contrast and quantify the recent impacts of cyclone Sidr and anthropogenic degradation on this ecosystem. Our results, inferred from changes in radar backscatter, confirm already reported trends in coastline retreat for this region, with areas losing as much as 200 m of coast per year. They also suggest rapid changes in mangrove dynamics for Bangladesh and India, highlighting an overall decrease in mangrove health in the east side of the Sundarbans, and an overall increase in this parameter for the west side of the Sundarbans. As global environmental change takes its toll in this part of the world, more detailed, regular information on mangroves' distribution and health is required: our study illustrates how different threats experienced by mangroves can be detected and mapped using radar-based information, to guide management action.

“…Despite their importance, cultural ecosystem services remain poorly understood as they are commonly intangible and subjective, making them difficult to analyze and quantitatively value alongside biophysical or economic metrics (Hernández-Morcillo et al 2013;Satz et al 2013;Pleasant et al 2014). The often intangible nature of cultural ecosystem services also makes it difficult to quantify how their values may change through time, compared to tangible provisioning and regulating ecosystem services (e.g., Ray et al 2011).…”

Cultural ecosystem services are a function of people and place, so may change as a location transitions from rural to urban. Singapore has undergone rapid urbanization after its independence in 1965, with a concomitant decline in natural habitat extent and accessibility. Using coastal mangrove forests as a case study habitat, changing cultural values were explored with a novel array of techniques, including qualitative archival analysis (photographs, oral histories), current sources (publically uploaded social media photographs), and surveys of (a) the general public and (b) visitors to publically accessible mangroves. Cultural value changed through time, with a significant transition from intrinsic, intrapersonal values (spiritual, cultural heritage) to instrumental, interpersonal values (recreation, education). Additionally, cultural value varied between different mangroves depending on their public accessibility, and the evolving degree of human interaction with the ecosystem as urban development occured. Cultural values change as development transitions, though mangroves still play an important cultural role in a heavily urbanized environment.

“…Several initiatives [like Mitra et al (2011) and Ray et al (2011)] were taken to characterize the standing stock of biomass and carbon content in the Indian Sundarban as well. Mukhopadhyay et al (2015) recently carried out an assessment to characterize the changes in mangrove species assemblages in the Bangladesh Sundarban and predicted the future scenario of species composition.…”

Blue Carbon Stock of the Bangladesh Sundarban Mangroves: What could Be the Scenario after a Century?

et al. 2016

The total blue carbon stock of the Bangladesh Sundarban mangroves was evaluated and the probable future status after a century was predicted based on the recent trend of changes in the last 30 years and implementing a hybrid model of Markov Chain and Cellular automata. At present 36.24 Tg C and 54.95 Tg C are stored in the above-ground and below-ground compartments respectively resulting in total blue carbon stock of 91.19 Tg C. According to the prediction 15.88 Tg C would be lost from this region by the year 2115. The low saline species composition classes dominated mainly by Heritiera spp. accounts for the major portion of the carbon sock at present (45.60 Tg C), while the highly saline regions stores only 14.90 Tg C. The prediction shows that after a hundred years almost 22.42 Tg C would be lost from the low saline regions accompanied by an increase of 8.20 Tg C in the high saline regions dominated mainly by Excoecaria sp. and Avicennia spp. The net carbon loss would be due to both mangrove area loss (~510 km 2 ) and change in species composition leading to 58.28 Tg of potential CO 2 emission within the year 2115.
