“…El Niño events, marked by anomalously warm SSTs, and La Niña events, marked by anomalously cool SSTs, cause changes in the Walker Circulation, an atmospheric system in which westerly “trade winds” across the surface of the Pacific Ocean rise over the western Pacific, causing higher air pressure, and return eastwards aloft [ 8 ]. During El Niño events, the Walker Circulation is significantly diminished, resulting in changes to the Bengal Delta’s atmosphere such as higher regional temperatures [ 9 , 10 ] and reduced precipitation [ 11 , 12 ]. The IOD refers to a similar oscillating climate phenomenon which occurs within the Indian Ocean and describes the relative changes in SST between the eastern and western sides.…”

Background In the Bengal Delta, research has shown that climate and cholera are linked. One demonstration of this is the relationship between interannual ocean-atmospheric oscillations such as the El Niño Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). What remains unclear in the present literature is the nature of this relationship in the specific context of Kolkata, and how this relationship may have changed over time. Results In this study, we analyse the changing relationship between ENSO and IOD with cholera in Kolkata over recent (1999–2019) and historical (1897–1941) time intervals. Wavelet coherence analysis revealed significant non-stationary association at 2–4 year and 4–8 year periods between cholera and both interannual timeseries during both time intervals. However, coherence was notably weakened in the recent interval, particularly with regards to ENSO, a result supported by a complementary SARIMA analysis. Similar coherence patterns with temperature indicate it could be an important mediating factor in the relationship between cholera and oscillating climate phenomena in Kolkata. Conclusions This study reveals a shifting relationship between cholera and climate variables (ENSO and IOD) in Kolkata, suggesting a decoupling between environmental influences and cholera transmission in recent years. Our results therefore do not suggest that an intensification of ENSO is likely to significantly influence cholera in the region. We also find that the relationship between cholera and interannual climate variables is distinct to Kolkata, highlighting the spatial heterogeneity of the climate-cholera relationship even within the Bengal Delta.

“…Climate change has a widespread impact on world economic, social, and political activities and disrupts the people’s way of life massively ( Brooks et al, 2009 ; Du et al, 2013 ; Bergquist et al, 2019 ). As a result, one of the myriad problems that people face worldwide is the harmful effects of climate change ( Wang et al, 2019 ; Uddin et al, 2022 ). It has already been documented that climate change, which has a detrimental consequence on the lives and livelihoods of the world population, is predicted to be one of the most significant risks to economic progress of developing countries ( IPCC, 2014 ; Tol, 2018 ; Wrathall et al, 2019 ).…”

Climate change induced human displacement in Bangladesh: Implications on the livelihood of displaced riverine island dwellers and their adaptation strategies

et al. 2022

In Bangladesh, many people are being displaced in riverine island (char) areas every year due to climate change and its associated natural catastrophes. This study intends to investigate the impact of climate change on internally displaced char people’s lives and livelihoods along with local adaptation strategies and hindrances to the coping mechanism. Data have been collected from 280 internally displaced households in two sub-districts. A mixed-method approach has been considered combined with qualitative and quantitative methods. The results disclose that frequent flooding, riverbank erosion, and crop loss are the leading causes for relocation, and social relations are impeded in the new place of residence. Increasing summer and winter temperatures, recurrent flooding, severity of riverbank erosion, and expanding disease outbreaks are also important indicators of climate change identified by displaced people, which are consistent with observed data. This study also reveals that almost all households come across severe livelihood issues like food shortage, unemployment and income loss, and housing and sanitation problems due to the changing climate associated with disasters in the former and present places. In response to this, the displaced people acclimatize applying numerous adaptation strategies in order to boost the livelihood resilience against climate change. However, fragile housing, financial conditions, and lack of own land are still the highest impediments to the sustainability of adaptation. Therefore, along with the government, several organizations should implement a dynamic resettlement project through appropriate scrutiny to eradicate the livelihood complications of internally displaced people.
