    The livelihoods of coastal people are at risk as shoreline migration is accelerated by climate change. To safeguard these communities and maintain their economy, it is imperative to strengthen resilience via adaptive strategies. Therefore, this study aims to estimate the rates and impacts of physical shoreline migration over the past 9,000 years using geospatial analysis and focus on understanding the livelihood resilience of coastal at-risk communities using in-depth interviews with environmental experts. The dynamic system of the Ganga-Brahmaputra-Meghna is highly complex and causes continuous shoreline migration. Historical data and more recent satellite remote sensing imagery analysis identified that the shrinking of the delta system has resulted from the migration of the shorelines at the mouth of the river system. Since 5,000 BP, it has been expanding towards the Bay of Bengal – meaning land gains at the coast. Land gain provides an opportunity for the extension of coastal communities but also increases their vulnerability to natural hazards. Moreover, by 2050, the salinity isoline with a 5-ppt is expected to shift inland by ⁓8 km in the south-east (Bhola-Patuakhali) and ⁓24 km in the southwest (Khulna-Satkhira) region. The in-depth interviews reveal several adaptive practices to effectively deal with the situation, including community knowledge, stakeholder engagement, local-led adaptation, and most importantly, temporal migration. The findings also highlighted the urgent need for an adaptation plan for the sustainability and resilience of coastal communities, considering indigenous knowledge with local cultural orientation and incorporation of scientific standards.

    Evaluating resilience of coastal communities upon integrating PRISMA protocol, composite resilience index and analytical hierarchy process
    (Elsevier, 2024-01-18) Ha-Mim, Nur Mohammad; Hossain, Md. Zakir; Islam, Md. Tariqul; Rahaman, Khan Rubayet
    This research intends to investigate the resilience of coastal communities to natural hazards upon adopting: (i) Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol as a novel approach for the selection of resilience indicators and major components; (ii) Analytical Hierarchy Process to generate a weight for each indicator and major component of resilience; and (iii) indexing method to calculate the extent of resilience for each community. The results highlight that 25.81 % of the communities in the study area are registered in the very low to low resilience class, whereas 58.07 % are classified as very high to high. Additionally, this research identifies 11 critical action areas for building resilience in Khulna City, which is crucial for major stakeholders in setting up development strategies and plans for disaster risk reduction and sustainability.
