“…The same pattern is observed in our household-scale risk assessment (Table 2), although the variables used at regional and local scales are different. The central coastline is also found highly exposed to the impacts of sea level rise, tidal flooding and storm surge in literature (Sarwar 2013;Sarwar and Islam 2013). The lowest average household vulnerability and the highest exposure value observed for households of the eastern zone were also noticed at regional scale (Table 1).…”

“…Non-structural measures include policies, preparedness plans and forecasting before natural hazard strikes. We focus on adaptation practices implemented by the coastal inhabitants and their direct community (Sarwar and Islam 2013). The survey documented the implementation of a series of adaptation practices, including DRR (Disaster Risk Reduction) actions in five sectors (i.e.…”

People's vulnerability, exposure and capacity are key components of a risk assessment. Index-based methodologies have proved useful to document spatial variation in risk-controlling factors. The objective of this study is to propose a methodology to derive quantitative indicators of household vulnerability, exposure and capacity to assess household's risk and its spatial variation. The method is applied to six unions of the coastal region of Bangladesh, including three offshore islands. Field data are collected by questionnaire survey of 609 households and 6 focus group discussions. Using conventional data conversion and aggregation methods and principle component analysis (PCA), the variables are summarized into a small set of dimensions to derive vulnerability and capacity scores. Result shows that households of islands are generally more vulnerable to natural hazards than nearby onshore unions. Unions of the central coast of Bangladesh are characterized by households with higher vulnerability and lower capacities than two other parts. The fatality rate of cyclone SIDR at village level is used to validate the spatial variation of household risk for one surveyed union. The proposed methodology and produced maps could support national to local government bodies in assessing household risk and identifying locations where to implement specific risk reduction measures.

“…Soil salinity in Bangladesh's southwest coastal region varies depending on the time of year, the year itself, and the location (Sarwar & Islam, 2013). Saltwater currently intrudes as far as 110 miles inland, seeping in by way of rivers and channels, especially from January through June, when there is less rainfall and insufficient downstream flow of freshwater from the Ganges and its distributaries (Food and Agriculture Organization of the United Nations, 2009; Haque, 2006; M. H. Rahman et al, 2011a).…”

Salinity and food security in southwest coastal Bangladesh: impacts on household food production and strategies for adaptation

et al. 2021

The rising salinity of land and water is an important, but understudied, climate change-sensitive trend that can exert devastating impacts on food security. This mixed methods investigation combines salinity testing with qualitative research methods to explore these impacts in one of the most salinity-affected regions in the world—the Ganges River Delta. Data collection in 2015 and 2016 undertaken in Bangladesh’s southwest coastal region and Dhaka consisted of 83 in-depth household and stakeholder interviews, six community focus groups, and salinity testing of 27 soil and 45 surface and groundwater samples. Results show that household food production is a multifaceted cornerstone of rural livelihood in the southwest coastal region, and virtually every component of it—from rice plantation and homestead gardening to livestock cultivation and aquaculture—is being negatively affected by salinity. Although households have attempted multiple strategies for adapting food production, effective adaptation remains elusive. At the community level, improved irrigation and floodplain management, as well as restrictions on saltwater aquaculture to abate salinity, are viewed as promising interventions. However, the potential of such measures remains unrealized on a broad scale, as they require a level of external resources and regulation not yet provided by the NGO and government sectors. This study elucidates issues of accessibility, equity, and governance surrounding agricultural interventions for climate change-related salinity adaptation, and its findings can help inform the community of organizations that will increasingly need to grapple with salinity in order to guarantee food security in the context of environmental change.

“…However, there is significant uncertainty concerning changes in rice production/yield associated with climate change (Karim et al 1996;Ruane et al 2013) as the effects vary in the different studies (Rimi et al 2009;Sarker et al 2012Sarker et al , 2014Amin et al 2015). Climate change may also indirectly affect food production in coastal areas because of salinity intrusion and increased yield variability causing reduced food availability (Parvin and Ahsan 2013;Sarwar and Islam 2013). Table 1 shows that some assessments include the location to ascertain the regional variations of climate change impact on rice yield, particularly at the broad climatic zone or agro-ecological zones (Ruane et al 2013).…”

Background Food security globally depends primarily on three components: food availability, food access, and food utilization. Regional variations of these components may affect food security via spatial differences in natural, social or economic conditions and the interaction of these in a complex environmental system. Purpose It is important to understand the regional variation of food security, particularly where and under what natural and socio-economic circumstances people become vulnerable to low food security in a country. Methods This article provides an overview of food security in Bangladesh in terms of the three main components, identifies knowledge gaps in present food security research, reviews possible impacts of climate change on food security, and sourced a wide range of spatio-temporal data relevant for food security. Results The study highlights potentials and indicates different processes to develop spatially informed food policies in a country, particularly focuses on Bangladesh. This will contribute to improved food security by considering regional food security conditions, region-specific deficits, climate change, other future risks, and devises actions related to the respective components. Conclusion The study concludes that different processes can provide a foundation for policy development and these will advance research-policy linkage to improved food security.
