“…The storm surges that create saltwater intrusion far into Bangladesh, permeate the soil and freshwater systems, such as rivers and ponds (Brindha et al, 2014;Zahid et al, 2018). This is seen in Table 5, as the river samples show a disproportionately high salinity value.…”

The southwestern coastal regions of Bangladesh (SWCRB) are highly exposed to saltwater intrusions brought about through cyclones and storm surges. These salinity intrusions are contributing to soil and water salinity in the coastal areas. This study aimed to determine the impact of these salinity intrusions on the quality of water and soil in three vulnerable coastal areas. In this investigation, water and soil samples were collected and analysed for pH, electrical conductivity (EC) and other trace elements. The analysis found many of the parameters to be higher than the recommended values. The study found that in soil samples there was a significant correlation between OM and ECe dS/m, as well as K and TN; and a highly significant correlation between TN and OM. This study further examined the historical salinity data at low and high tides to determine any patterns occurring alongside storm surges and cyclones. Water salinity statistics were obtained from the three locations of the Bangladesh Water Development Board (BWDB), which neighbours the study area. A Digital Evaluation Model (DEM) predicts the salinity induced by storm gushes in the corresponding impacted zones. Lastly, the study compared projections for future storm surges at current and predicted sea levels. Potential storm gushes circumstances from 1 to 9 m can impact up to 33% of the nation and 97% of the Shyamnagar Upazila. The occurrence of cyclone-related storms will increase and make cultivation and settlement in the region difficult. The predicted sea-level rises and saltwater contamination will intensify the adverse effects of salinity.

The composition of groundwater governs the drinking and irrigation water suitability. A large part of the coastal region of Bangladesh is affected and is responsible for changing the composition of the groundwater. This research attempted to observe the groundwater quality of the Bhola Sadar and Char Fasson upazilas in coastal Bangladesh. Twenty-eight (28) water samples, 27 at depths of 260–430 m (850–1400 ft) and 1 from a crop field, were collected and analyzed. The quality of water samples was determined through the evaluation of odor, color, turbidity, electrical conductivity, pH, total dissolved solids, nitrate (NO3−), ammonium (NH4+), sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn) and arsenic (As) ions. An Atomic Absorption Spectrophotometer was used for heavy metal analysis. The outcomes were compared with the drinking water quality of Bangladesh and the World Health Organization. The results showed that the average values of nearly all of the parameters were underneath or within the standard level, representing that the groundwater was appropriate for drinking purposes. The water quality parameters were also compared with the irrigation water quality of Bangladesh and the Food and Agriculture Organization. It was found that the collected samples were also suitable for irrigation. To do this, the soluble sodium percentage, sodium adsorption ratio, magnesium adsorption ratio, Kelley’s ratio, and total hardness were calculated. The novelty of this research is that, despite being in a coastal district, the deep aquifer water of Bhola was appropriate for drinking and irrigation purposes.

“…The fundamental reasons are identified as the climate-induced vulnerabilities and the higher unemployment rate in Bangladesh (Assaduzzaman et al, 2020;Rudnick, 2009). The geographic position and low-lying topography cause more vulnerability, hindering socioeconomic development (Zahid et al, 2018). Due to sea level rise-induced vulnerability, the people of coastal Bangladesh often adapt themselves through internal and cross-border migration.…”

Migration as an Adaptation Strategy: A Bibliometric Analysis

Considering the capability approach of Amartya Sen, in many instances, migration is an adaption strategy that is no longer freedom of choice; rather, people are forced to choose it. Specifically, people often choose migration for adaptation due to climate and environmental vulnerabilities. This Bibliometric analysis aims to provide a detailed overview of how migration is considered an adaptation strategy using the Scopus database. The search query includes 'migration,’ 'adaptation', 'vulnerability', and 'climate change' as the keywords. A total of 7,335 scientific documents, including books, book chapters, articles, and review papers for 2011-2021, were analyzed using VOSviewer software. The lexical network analysis suggests a strong connection between migration and adaptation. Moreover, the spatial network analysis suggests that the migration-related research works are primarily concentrated in the USA, the UK, and Australia. The findings of an intensive review of 38 Scopus index migration literature suggest that migration is the ultimate effect of climate change, and the researchers termed this an 'adaptation strategy'. Although numerous dimensions of migration and adaptation strategy have been explored in the literature, however, future research options are still available in the field of migration-adaptation comparing circular and permanent migration, gendered dimension from the left-behind perspective, cultural diaspora between the migrants and receiving country, policies on alternative adaptation strategies, adaptation due to freedom of choice and forced migration from the wellbeing perspective. Moreover, heightened research collaboration is strongly suggested among the top migrant-sending and receiving countries to get more insights and policy formulation.
