Bangladesh has been identified as one of the 9th most vulnerable disasters affected and nearly 112 million people have directly affected by the climate change (CC)-induced catastrophic calamities within the last two decades1. This region has been subjected to recurring hydro climatic disasters2, 3, 4. However, the frequency and severity of CC-posed incidents have been assumed in growing and adversaries likewise5,6,44,48. The country has also been considered highly susceptible to sea level rise because of its low-laying geographic settings at the edge of the Bay of Bengal, coastal floodplain and low lying topography7, 8, 23–24, 26, 44, 48. Trends analysis have been displayed a rising tendency of temperature9, 10 and rainfall with seasonal and spatial variabilities9, 11, 12 have been deemed to have high surges, sea wave, high tidal bores and fluctuation, inundation of salinity intruded water on the coastline water bodies and flood plain11, 13, 14, 23–24, 44. The variability of climatic factors and its changes, impacts, and vulnerabilities, are causing widespread distress on coastal dwellers15, 16, 33, 46, 48–49. Recent studies show that the CCI events have much influence on the livelihood assets of small scale fishers (SSF) and coastal fishers15, 17–19, 40–41. The fishers have suffered of extreme poverty and poverty influenced by different seasonal vulnerability and climatic induced shocks and hazards15, 17, 19–20, 40–41. The above miseries and cruelty lead them to pushing and pulling into poverty15,21. CC-induced extreme events such as sea level rise, temperature fluctuations, increased rainfall, cyclones, storms, coastal-bank erosion, inundation, and heavy flash floods adversely affected the coastal fisher's and non-fisher’s livelihoods, especially in terms of economic losses15, 21–25. Higher salinity intrusion levels have negative effects on coastal agriculture, cultivation, and aquaculture, as well as domestic and industrial water use, and overall production and development26–29. These disaster-originated incidences have also created severe vulnerability of losing domestic assets including standing cash crops, household’s resources of the coastal extreme poor, poor and marginal inhabitants of the 16 coastal districts9, 15, 24, 29–33, 44–48. Extreme CC-induced events have a significant negative impact on their major livelihood elements, including damage of household assets, reduced agriculture production, extinction of livestock, and loss in fisheries, putting them into socio-economically impoverished status, health risks, and food insecure9,15,24,30, 33. Every year CC-induced adversaries and events make them asset loss, jobless and income vulnerable by creating unfavorable environment for deep sea and off shore fishing, consistently make coastal fishers paralyzed and inactive23, 33–35,42,48,50. Notably, most studies have used different social, or policy-level perspectives and approaches to explore their ideas. The limited number of studies has been carried out showing coastal dwelling fishers' household-level economic penalties due to the severity and frequency of the CC-induced disasters based on fishers’ insights in relation to their impoverished livelihood status. Moreover, the household-specific livelihood approach of the coastal fisher communities living in about 710-kilometer-long coastline zones of Southern Bangladesh ranging from Cox’s Bazar to Satkhira has not been explored together in the previous studies. In addition, coastal dwelling fisher communities have been evidently the frontline victims of CC-induced catastrophic disasters16, 23–26, 29, 31, 44–49 and it has also been a government concern to manage coastal zones and to develop livelihood status by escaping them from the curse of poverty line. Therefore, it is necessary to identify the climatic factors responsible for the coastal fishers’ household-level different assets’ losses and other predictors that drive them into a vicious poverty cycle or interfere with their getting out of impoverished socio-economic status. The principal objective of this study was to identify financial penalties equivalent to the damages of households and fisheries assets resulting from climate change-induced (CCI) calamities and adversities of environmental weather events among the coastal fishers of Bangladesh.
