“…Simplified, stylized migration assumptions in models can however provide useful comparative insights, and thus, we only consider economic and environmental push factors and remove financial, network, cultural or family barriers to migration. Informed by the existing literature on the impacts of chronic and acute environmental change and locally specific knowledge of coping strategies (Adger et al 2018;Lázár et al 2017), in this application, a household is identified as susceptible to migration and removed from the study area, when any of the following thresholds are exceeded:…”

Contrasting development trajectories for coastal Bangladesh to the end of century

Bangladesh is one of the most climate-sensitive countries globally, creating significant challenges for future development. Here we apply an integrated assessment model — Delta Dynamic Integrated Emulator Model (ΔDIEM) — to the south-west coastal zone of Bangladesh to explore the outcomes of four contrasting and plausible development trajectories under different climate and socio-economic scenarios: (1) embankment rehabilitation; (2) build elevation via controlled sedimentation; (3) planned migration (managed retreat) and (4) ‘do nothing’ (unplanned migration and abandonment). Embankment rehabilitation reduces flood risk, but at a high economic cost and enhancing waterlogging. Planned and unplanned migration combined with limited infrastructure management and governance both result in significant abandonment. Building elevation through sedimentation has the potential for increased environmental and economic sustainability but raises equity issues. Poverty and inequality persist across all scenarios, and outmigration from the coastal zone continues, although the magnitude is sensitive to assumptions about sea-level rise, socio-economic development and development trajectory. Integrated assessment tools linking the environment, people and policy choices, such as the ΔDIEM used here, highlight the complex interactions occurring in a dynamic delta environment. Such analysis supports informed management, development and adaptation.

“…With the development of the social economy and the growth of population, the contradiction between human and land has intensified [2,76], and the impact of human disturbance on habitats has been growing, along with changes in land use, this interaction is closely related to human well-being [77]. In order to improve human well-being and achieve sustainable development, we need to comprehensively understand and evaluate the health of complex ecosystems, in various ways [51]. To this end, the InVEST model provides us with good research methods and perspectives [11,21].…”

“…Human activities often cause a dramatic reduction of biodiversity, especially in the deltaic areas [50,51], the application of biodiversity research approach in these areas is of great significance [51]. Therefore, it is necessary to conduct a systematic evaluation of the HQ in TLB for decision-making regarding a sustainable development of the basin [52].…”

Habitat quality (HQ) is of great significance to regional sustainable development, which is a key link for regional ecological security and human welfare. Assessing the temporal and spatial evolution of HQ caused by land-use change could provide a scientific basis for regional ecological protection and land management. Here, based on the ArcGIS platform and the InVEST model, this study quantified the spatial and temporal evolutions of land use, landscape patterns, and HQ from 1985 to 2015, in Taihu Lake Basin (TLB). Hotspot analysis tools were used to identify the spatial agglomeration and evolution characteristics of HQ in TLB. The results showed that, (1) the land use and landscape pattern in TLB experienced dramatic change process during 1985–2015, with the dominating conversion being from farmland to construction land, which led to an increase in landscape heterogeneity and fragmentation. (2) The HQ was generally reduced in the past 30 years. In particular, the decline of HQ was extremely severe in the peripheral area of cities and roads, due to urban sprawl. (3) Regarding the spatial distribution of HQ, the northern and eastern areas were generally higher, while the western and southern areas were generally lower. The hotspots areas were mainly located in the southwestern mountain area and west-central lake area, while the cold spots areas were mainly located in urban areas in the north and the east. (4) The area and degree of habitat degradation were both increased significantly due to land-use change, and the degradation of the Taihu Lake was highlighted. Strengthening the ecological environment management and reducing the threat of urban expansion to the HQ is urgently required. This study could help understand HQ of the TLB and provide a scientific basis for decision-makers.

“…The literature suggest that Bangladesh faces worse vulnerability due to climate change and sea-level rise [1][2][3][4][5][6][7][8][9]. The tipping point of this vulnerability can turn disastrous, as the country faces severe multiple and frequent natural calamities, such as cyclones and storm surges, erosion, various types of floods, landslides, severe salinity intrusion into agricultural land, droughts due to withdrawing water from up streams, rising water on the edge of coastal land due to sea level rise, extension of arsenic contamination, reducing soil fertility due to overuse of pesticides and so on.…”

The concept of household vulnerability along with sustainable livelihoods has currently emerged as a significant concept in the climate change vulnerability and adaptation (CCVA) literature. In this paper, the vulnerability of Bangladesh has been assessed by using multiple regression analysis where twenty two effective variables have been chosen from the surveyed data given by Bangladesh Bureau of Statistics. The vulnerability has been functioned by three main stream components: Exposure, sensitivity and adaptive capacity, which have been adopted from the reports of Inter-Governmental Panel on Climate Change (IPCC) and other scientific literature. Based on the higher significance and coefficient values, the variables, which have direct relationships and impact on income and illness, have been identified and prioritized. Household income and illness are the known driving forces for assessing the vulnerability. The motion of centripetal and centrifugal forces in decision making mechanisms, which are the main driving contributions of this paper, have been dealt as a new way to envisioning vulnerability and adaptation decision. Based on the prioritized variables some actions along with solutions have been taken into consideration, which have enormous significance in addressing localized plans and actions in order to reduce potential households’ vulnerability under climate change regimes in Bangladesh.
