“…The regions close to coastal vegetation are likely to be less susceptible to cyclones as they work as natural shields. In addition, embankments play a vital role in protecting agricultural crops and houses from the inundation of tropical cyclone-induced storm surges (Mullick et al 2019). The present study used the presence or absence of embankments from LGED data to create the spatial layer of embankment (Figure 5d).…”

“…Cyclone Aila that made landfall in 2009 caused 190 deaths; injured 7000 people; and destroyed more than 500,000 houses (Ahmed et al 2016). Due to lowlying coastal regions, many people will be at risk under the scenario of storm surges with future sea-level rise (Mullick et al 2019;Rana et al 2010).…”

“…Studies focusing on vulnerability assessment have so far not been comprehensive or appropriately delineated, especially in the coastal region of Bangladesh. Although a large number of vulnerability studies [27,34,35,38,42,44,45,46,47,48,49,50,51,52,53,54,55] are being conducted, almost none of the previous studies addressed integrated agriculture (i.e., crops, fisheries, and livestock) or took into account the connections between different spatial scales, addressed multiple hazards, or led to the formulation of intervention planning to enhance adaptation capacity. These latter two issues comprise a global research gap [56].…”

The adverse impacts of climate change exert mounting pressure on agriculture-dependent livelihoods of many developing and developed nations. However, integrated and spatially specific vulnerability assessments in less-developed countries like Bangladesh are rare, and insufficient to support the decision-making needed for climate-change resilience. Here, we develop an agricultural livelihood vulnerability index (ALVI) and an integrated approach, allowing for (i) mapping out the hot spots of vulnerability distribution; (ii) identifying key factors of spatially heterogeneous vulnerability; and (iii) supporting intervention planning for adaptation. This study conceptualized vulnerability as a function of exposure, sensitivity, and adaptive capacity by developing a composite index from a reliable dataset of 64 indicators comprising biophysical, agro-ecological, and socioeconomic variables. The empirical studies of coastal Bangladesh revealed that Bhola, Patuakhali, and Lakshmipur districts, around the mouth of the deltaic Meghna estuaries, are the hot spot of vulnerability distribution. Furthermore, the spatially heterogeneous vulnerability was triggered by spatial variation of erosion, cyclones, drought, rain-fed agriculture, land degradation, soil phosphorus, crop productivity, sanitation and housing condition, infant mortality, emergency shelters, adoption of agro-technology. The integrated approach could be useful for monitoring and evaluating the effectiveness of adaptation intervention by substituting various hypothetical scenarios into the ALVI framework for baseline comparison.

“…Many studies have been devoted to gaining a clear understanding of the processes of surge intensification and wind movement associated with tropical cyclones using spatial modeling and simulation techniques (Murty et al 2016;Singh et al 2019;Sahoo and Bhaskaran 2019a;2019b). Other studies have variously focused on risk and vulnerability assessment related to tropical cyclones using geospatial techniques (Quader et al 2017;Hoque et al 2018Hoque et al , 2019Mullick et al 2019;Alam et al 2020), cyclone resilience (Islam et al 2020), relationships between meteorological parameters and cyclone genesis (Kundu et al 2001), and physical changes on land and in oceans during cyclones (Chauhan et al 2018).…”

Tropical cyclones wreak havoc on the lives of coastal populations, especially in marginalised communities in developing countries where cyclone impacts are disproportionately lethal compared to developed countries. These populations must implement measures that enable them to prepare for, respond to, and recover from cyclone impacts. Using empirical evidence, this study presents a spatio-temporally explicit, index-based assessment technique to assess social resilience to tropical cyclones. The key components of social resilience were extracted by Principal Component Analysis; distinct resilience indices were generated and mapped for the three disaster phases. The most influential components were then aggregated into an Effective Social Resilience Index (ESoRI), which was mapped across the study area. The technique was applied in a coastal sub-district of Bangladesh to demonstrate the approach. Basic preparedness training, emergency response, social bonding, and reconstruction and rehabilitation strongly influenced resilience in ways that corresponded closely to the phases of the disaster-management cycle: preparedness, response, and recovery. The spatial pattern of resilience revealed that social resilience varies significantly in time and space within a circumscribed locale. Importantly, areas close to the sea and rivers were found to be more resilient despite their high exposure to cyclones and lack of external support. This study will guide policymakers concerned with resilience building on a priority basis such as those working in resource-scarce conditions of developing countries.
