Climate change-derived extreme heat phenomena are one of the major concerns across the globe, including Bangladesh. The appraisal of historical spatiotemporal changes and possible future changes in heat index (HI) is essential for developing heat stress mitigation strategies. However, the climate-health nexus studies in Bangladesh are very limited. This study was intended to appraise the historical and projected changes in HI in Bangladesh. The HI was computed from daily dry bulb temperature and relative humidity. The modified Mann-Kendal (MMK) test and linear regression were used to detect trends in HI for the observed period (1985–2015). The future change in HI was projected for the mid-century (2041–2070) for three Representative Concentration Pathway (RCP) scenarios, RCP 2.6, 4.5, and 8.5 using the Canadian Earth System Model Second Generation (CanESM2). The results revealed a monotonic rise in the HI and extreme caution conditions, especially in the humid summer season for most parts of Bangladesh for the observed period (1985–2015). Future projections revealed a continuous rise in HI in the forthcoming period (2041–2070). A higher and remarkable increase in the HI was projected in the northern, northeastern, and south-central regions. Among the three scenarios, the RCP 8.5 showed a higher projection of HI both in hot and humid summer compared to the other scenarios. Therefore, Bangladesh should take region-specific adaptation strategies to mitigate the impacts of HI.

“…Drought affects a million people and causes tremendous environmental degradation, social crisis, livelihood problems, economic disruption, and loss of lives compared with other climate-related disasters like floods, cyclones (Habiba and Shaw 2012). Of these effects, drought is a major threat to reduce and loss crop production in Bangladesh, which has been influenced by regional climate change in recent times (Habiba et al 2014;Islam et al 2014;Mardy et al 2018;Zinat et al 2020). Furthermore, the northern region covering the Teesta River Basin is one of the largest crops producing regions of Bangladesh, of which more than 40% are rain-fed agriculture and, this Basin has experienced different levels (e.g.…”

Disaster risk perception, as well as risk appraisal, play a pivotal role in making the disaster risk reduction policy. This study examines the actual vs perceived drought risks by constructing risk indices at the household and expert levels using survey data from the lower Teesta River Basin in northern Bangladesh. Survey data were collected from 450 farmers based on the structural questionnaire. A composite drought risk index was developed to understand households’ perceived and actual risks in the designated areas. The results show that the actual and perceived risk values differ significantly among the three designated sites of Ganai, Ismail, and Par Sekh Sundar. The risk levels also differ significantly across the household’s gender, income, occupation, and educational attainment. People with poor socio-economic status are more prone to drought risk than others. Results also reveal that the mean level of perceived risk agrees well with the actual risk; females perceive comparatively higher risk than males. Expert views on drought risk are similar to the individual household level perceived risk. The outcomes of this study would help the policy-makers and disaster managers to understand the concrete risk scenarios of the study areas and to take timely and appropriate disaster risk reduction actions for ensuring a drought-resistant society.

Disaster risk perception and risk appraisal are essential in formulating an appropriate disaster risk reduction policy. This study examines the actual vs perceived drought risks by constructing risk indices at the household and expert levels using survey data from the lower Teesta River Basin in northern Bangladesh. The survey data were collected from 450 farmers using a structured questionnaire conducted between August and September 2019. A composite drought risk index was developed to understand households’ perceived and actual risks in the designated areas. The results show that the actual and perceived risk values differ significantly among the three case study sites locally known as Ganai, Ismail, and Par Sekh Sundar. The risk levels also differ significantly across the households’ gender, income, occupation, and educational attainment. People with insolvent socioeconomic status are more prone to drought risk compared to others. Results also reveal that the mean level of perceived risk agrees well with the actual risk, whereas females perceive comparatively higher risk than their male counterparts. Expert views on drought risk are similar to the individual household level perceived risk. The outcomes of this study would assist the policymakers and disaster managers to understand the concrete risk scenarios and take timely disaster risk reduction actions for ensuring a drought-resistant society.
