“…Several studies have been conducted on drought assessment in Bangladesh and its impacts [11][12][13][14][15][16][17][18][19]. Most of these studies quantify drought severity by using the standardized precipitation index (SPI) [20], while very few studies have been conducted using the Palmer drought severity index (PDSI) [21] and the Standardized Precipitation Evapotranspiration Index (SPEI) [22].…”

This study aims to assess the spatiotemporal characteristics of agricultural droughts in Bangladesh during 1981–2015 using the Effective Drought Index (EDI). Monthly precipitation data for 36 years (1980–2015) obtained from 27 metrological stations, were used in this study. The EDI performance was evaluated for four sub-regions over the country through comparisons with historical drought records identified by regional analysis. Analysis at a regional level showed that EDI could reasonably detect the drought years/events during the study period. The study also presented that the overall drought severity had increased during the past 35 years. The characteristics (severity and duration) of drought were also analyzed in terms of the spatiotemporal evolution of the frequency of drought events. It was found that the western and central regions of the country are comparatively more vulnerable to drought. Moreover, the southwestern region is more prone to extreme drought, whereas the central region is more prone to severe droughts. Besides, the central region was more prone to extra-long-term droughts, while the coastal areas in the southwestern as well as in the central and north-western regions were more prone to long-term droughts. The frequency of droughts in all categories significantly increased during the last quinquennial period (2011 to 2015). The seasonal analysis showed that the north-western areas were prone to extreme droughts during the Kharif (wet) and Rabi (dry) seasons. The central and northern regions were affected by recurring severe droughts in all cropping seasons. Further, the most significant increasing trend of the drought-affected area was observed within the central region, especially during the pre-monsoon (March–May) season. The results of this study can aid policymakers in the development of drought mitigation strategies in the future.

“…However, a decreasing trend of precipitation was observed in the winter season [1]. The overall increasing rate of warming in Bangladesh is higher than the present increasing rate of global warming, and this trend is expected to continue over the 21st century [2][3][4]. Notably, Bangladesh has been suffering from frequent natural disasters.…”

The impacts of climate change on precipitation and drought characteristics over Bangladesh were examined by using the daily precipitation outputs from 29 bias-corrected general circulation models (GCMs) under the representative concentration pathway (RCP) 4.5 and 8.5 scenarios. A precipitation-based drought estimator, namely, the Effective Drought Index (EDI), was applied to quantify the characteristics of drought events in terms of the severity and duration. The changes in drought characteristics were assessed for the beginning (2010-2039), middle , and end of this century relative to the 1976-2005 baseline. The GCMs were limited in regard to forecasting the occurrence of future extreme droughts. Overall, the findings showed that the annual precipitation will increase in the 21st century over Bangladesh; the increasing rate was comparatively higher under the RCP8.5 scenario. The highest increase in rainfall is expected to happen over the drought-prone northern region. The general trends of drought frequency, duration, and intensity are likely to decrease in the 21st century over Bangladesh under both RCP scenarios, except for the maximum drought intensity during the beginning of the century, which is projected to increase over the country. The extreme and medium-term drought events did not show any significant changes in the future under both scenarios except for the medium-term droughts, which decreased by 55% compared to the base period during the 2070s under RCP8.5. However, extreme drought days will likely increase in most of the cropping seasons for the different future periods under both scenarios. The spatial distribution of changes in drought characteristics indicates that the drought-vulnerable areas are expected to shift from the northwestern region to the central and the southern region in the future under both scenarios due to the effects of climate change.

“…The vulnerability of Bangladesh to climate change is pronounced well in the literature. Rahman and Lateh () show the average temperature of the country rises by 0.2°C per decade. Rising temperature is found to be negatively associated with harvesting of Boro rice (Sarker, Alam, & Gow, ).…”

This study aims to compare environmental motives and performance of conventional and Islamic banks in Bangladesh. Green compliance index was developed based on the Bangladesh Bank (the central bank of Bangladesh) guidelines whereas information regarding governance variables is collected from the annual reports of 9 Islamic and 31 conventional banks. Results show Islamic banks are more environmentally friendly compared to their conventional counterparts. Board size is negatively related to green compliance whereas board independence and auditor's type do not have any significant influence on green compliance for both clusters of banks. Compliance with green banking policies enhances the reputation for Islamic banks and accountability and profitability for conventional banks. Results of this study provide useful information for regulatory authorities to formulate policies that are conducive to enhance bank's environmental performance.
