The principal nature-based solution for offsetting relative sea-level rise in the Ganges-Brahmaputra delta is unabated delivery, dispersal, and deposition of rivers' ~1 billion-tonne annual sediment load. Recent hydrological transport modeling suggests that strengthening monsoon precipitation 21st century could increase this delivery 34-60%; yet other studies demonstrate decline 15-80% if planned dams river diversions are fully implemented. We validate these modeled ranges by developing a comprehensive field-based budget quantifies supply under varying Holocene climate conditions. Our data reveal natural responses comparable to previously results suggest increased may be capable accelerated rise. This prospect naturally sustained presents possibilities beyond dystopian future often posed system, but implementation currently proposed would preclude such opportunities.

Migration can strengthen adaptation to climate change. The potential of migration-as-adaptation builds on a world intensifying global mobility and connectedness the increasing possibility geographically spreading risks. But what if is impeded connectivity disrupted? And happens distant places face risks simultaneously due systemic character or multiplicity crises? This paper points fundamental gaps in research migration-as-adaptation, which largely neglects questions limits. It argues that an understanding limits needs address (1) migration as inherent feature social systems under stress, (2) unequal contested nature goals, (3) immobility, disconnectedness simultaneous exposure core mechanisms limit adaptive migration. proposes novel translocal-mobilities perspective multi-scalar, multi-local, relational intersectional dynamics migration-as-adaptation. formulates for adaptation.

This study developed a geo-spatial framework for assessing multi-hazard threat on the Bangladesh coast, integrating environmental hazards (EH), geo-environmental attributes (GA), and anthropogenic modifications (AM) based their potential contribution to overall threat. For this purpose, fuzzy logic analytical technique was integrated with geospatial mapping.

Abstract Of growing research and policy interest are the experiences of people living under conditions climate change–induced environmental stress, which either unable to migrate (sometimes described as a ‘trapped population’) or seemingly unwilling do so ‘voluntarily immobile’). This paper problematises expands upon these binary categories: examining complex dimensionality non-migration form place relations, explored through qualitative study rural coastal Bangladeshi communities. Through 60 semi-structured interviews individuals from four communities in Kalapara region, analysis proffers qualitatively derived inter-related dimensions voluntary involuntary framed relations. These concern following: (1) livelihood opportunities, (2) obduracy, (3) risk perceptions, (4) social-structural constraints, with interplay between elements explaining diverse non-migratory experiences. In our analysis, ‘place obduracy’ is introduced concept describe differential speed change socio-cultural adaptation responses explain Our discussion provides insight into how best support non-migrant people’s adaptive capacity face emergency.

Migration is often understood to be a livelihood strategy cope with the effects of environmental threats and climate change. Yet, extent which migration decisions differ due type, severity, frequency events has been little explored. This paper employs household surveys in southwestern Bangladesh explore this research gap. A multinominal regression model used simulate reported future (200 sample households) context both rapid-onset (i.e. cyclone flood) slow-onset (salinity, siltation, riverbank erosion) phenomena. Results show: i) previous disaster experience increasing conflict community motivate near phenomena (salinity); (ii) economic strength self-efficacy increase non-migration intention contexts sudden events; (iii) pattern these influences on across demographics, including education, religion, age. Importantly, analysis shows that relationship between influenced by socioeconomic conditions. Therefore, supports adaptation planning specifically tailored type exposure extreme events.

Bangladesh has been witnessing across years, but underlying mechanism disaster-induced needs be explored and understood with changing climate conditions. The main objective this study is evaluate types patterns, auxiliary drivers perceived impact migration. A semi-structured questionnaire survey was carried out 155 Union-level key persons from five districts Bangladesh, collected qualitative data were thematically analyzed using NVivo. Irrespective type disaster, major spatial-temporal pattern temporary domestic rural urban areas. Comparing revealed some common economic drivers. comparison diagram also identifies several other which disaster-specific.
