“…Mousuni island is among the more vulnerable ones according to them too. Further, using satellite images from 1990 to 2015, Hajra et al (2017), argue a decline in agricultural land area in Ghoramara as well as Mousuni island. 3…”

The Sundarbans poses a unique challenge to policy makers. With rising sea level, large part of the area will be inundated and hence a climate adaption strategy needs to be in place. While there is a significant discussion regarding medium- and long-term strategies, preventing or mitigating such local level disasters need micro level data with minimum lag. In this article, we show how using satellite imagery can achieve both. With real-time data availability, one can map various villages, monitor their economic activities (primarily agriculture) and create a vulnerability mapping. While this article only highlights an extremely localised shock, such vulnerability mapping for the entire area will be an extremely useful tool for policy makers. We use Landsat images 2007–18 and perform clustering to map local area vulnerability in Mousuni island Sundarbans.

“…Both the Sagar and Patharpratima islands have been reclaimed, and about 90% of their inhabitants largely depend on agriculture and animal husbandry (Ghosh et al 2015). Paddy is the prime crop, where 69% of the total workers (Census Report of India 2011) are dependent on monocrop (Aman paddy) cultivation (Hajra et al 2018). Livestock was a valuable resource for the villagers.…”

“…Villagers were involved in the production of cattle, buffalo, sheep, goat, pig, duck, chicken and goose (Das & Tripathi 2013). Farmers are forced to seek alternative sources of income because to a lack of storage and insufficient earnings, especially during non-monsoon months (Hajra et al 2018). Mangroves have long been used by local communities as a supply of wood for cooking, heating and construction (Roy 2018).…”

Dynamics of methane and carbon dioxide emissions in the reclaimed islands of Sundarban mangrove ecosystem, India

The loss and deterioration of mangroves would lead to potentially important greenhouse gases (GHG) from the mangrove ecosystem. Seasonal variations of methane (CH 4 ) and carbon dioxide (CO 2 ) fluxes are studied in the Indian part of the Sundarban mangrove ecosystem. Considering the importance of CH 4 and CO 2 fluxes, a dynamic model is proposed here with CH 4 and CO 2 as state variables. The data used in the model are collected and analysed from the field over two years. The parameters that are taken from the literature sources are calibrated in the model. Sensitivity analysis is conducted to assess the valuable contribution of various parameters to the dynamics of CH 4 and CO 2 emissions from the mangrove beds. Model simulation results are appropriately validated with the observed data. Results showed that CH 4 and CO 2 fluxes were higher during monsoon. Pearson correlation was done to assess the relationships between emissions and all the physical-chemical factors involved in the model. Sensitivity analysis indicated that the temperature sensitivity (Q 10 ) was the system-sensitive parameter for CH 4 and CO 2 emissions. The soil moisture and relative light intensity were the sensitive parameters for CH 4 and CO 2 emissions, respectively. Model showed that the increase in the anthropogenic emissions including emissions from livestock and fossil fuel caused an increase of 2% of CH 4 and 3% of CO 2 in the system, respectively. The proposed model could be a tool for environmental managers to assess the emission process at different global locations.

“…As defined by the IPCC (2007), vulnerability is a function of sensitivity, exposure, and adaptive capacity [29]. However, the terminology of risk, as introduced in the fifth Assessment Report (AR5) of the IPCC 2014, defines it as the interplay of exposure, hazard, and vulnerability [2,30,31]. The present work is based on the AR5 methodology, which defines it as the function of exposure, hazard, sensitivity, and adaptive capacity.…”

Inhabitants of low-lying islands face increased threats due to climate change as a result of their higher exposure and lesser adaptive capacity. Sagar Island, the largest inhabited estuarine island of Sundarbans, is experiencing severe coastal erosion, frequent cyclones, flooding, storm surges, and breaching of embankments, resulting in land, livelihood, and property loss, and the displacement of people at a huge scale. The present study assessed climate change-induced vulnerability and risk for Sagar Island, India, using an integrated geostatistical and geoinformatics-based approach. Based on the IPCC AR5 framework, the proportion of variance of 26 exposure, hazard, sensitivity, and adaptive capacity parameters was measured and analyzed. The results showed that 19.5% of mouzas (administrative units of the island), with 15.33% of the population at the southern part of the island, i.e., Sibpur–Dhablat, Bankimnagar–Sumatinagar, and Beguakhali–Mahismari, are at high risk (0.70–0.80). It has been concluded that the island has undergone tremendous land system transformations and changes in climatic patterns. Therefore, there is a need to formulate comprehensive adaptation strategies at the policy- and decision-making levels to help the communities of this island deal with the adverse impacts of climate change. The findings of this study will help adaptation strategies based on site-specific information and sustainable management for the marginalized populations living in similar islands worldwide.
