Abstract Climate change has been recognised as a major concern in coastal hotspots exposed to multiple climate hazards under regionally specific characteristics of vulnerability. We review the emerging research and current trends academic literature on risk adaptation from human security perspective. The ecological socioeconomic developments are analysed for key areas, including infrastructure; water, food fisheries; health; mobility; conflict, taking different geographical contexts areas islands, megacities deltas into consideration. Compounding cascading interactions require integrative policy approaches address growing complexity. Governance mechanisms focus management adaptation, nature-based solutions community-based considering their synergies trade-offs. This perspective allows holistic view risks vicious circles societal instability systems interconnectedness dimensions necessary sustainable transformative most affected hotspots.

The impacts of climate change (CC) on all spheres human life are evident worldwide. Fish is the premier protein source, and its production in Bangladesh mainly dependent hatchery-based seed production. However, hatchery productivity disrupted every year due to CC. This study assesses CC fish hatcheries from perspective owners. A semi-structured questionnaire survey was conducted with 60 owners five sub-districts (Trishal, Mymensingh Sadar, Gouripur, Fulbaria, Muktagacha) district, highest aquaculture-producing zone Bangladesh. Characteristically, middle-aged highly educated, over a decade experience management. Likert scale results showed that concur evidence CC, as seen by changes air water temperatures, rainfall, sunlight intensity, well frequent natural disasters. Regression analysis erratic high temperature, solar radiation significantly influenced owners’ perceptions Principal component (PCA) used divide impact into 12 components. Maximum variance (>70%) observed could be explained problems related embryonic physiological development fry, environmental changes, disease outbreaks, poor growth broodfish. first PCA 50% variances, higher factor loadings, comprising gonadal maturation, low hatching rate, egg quality, fecundity, sperm quality confirmed operations were severe.

Assessing household's considered crucial step in avoiding the adverse effects catastrophe risks. This was conducted cyclone-prone district Barguna, Bangladesh. study's purpose evaluate this region's vulnerability. A questionnaire survey using convenience sample technique. door-to-door 388 households two Unions Patharghata Upazila, Barguna district, conducted. Forty-three indicators were selected assess The results quantified an index-based methodology with standardized scoring method. Where applicable, descriptive statistics have been obtained. In terms indicators, we also utilized chi-square test compare Kalmegha and Union. When appropriate, non-parametric Mann-Whitney U employed relationship between Vulnerability Index Score (VIS) union. According results, environmental (0.53 ± 0.17) composite index (0.50 0.08) significantly greater Union than They faced inequity government assistance (71%) humanitarian aid (45%) from national international organizations. However, 83% them underwent evacuation practices. 39% satisfied WASH conditions at shelter, whereas around half dissatisfied status medical facilities. Most (96%) rely only surface water for drinking. National organizations should comprehensive plan disaster risk reduction that encompasses all individuals, regardless race, geography, or ethnicity.

Abstract Effective climate change adaptation requires a thorough understanding of whether and how affected populations perceive climatic environmental changes. Existing research has been inconclusive regarding the consistency these perceptions compared to objective meteorological indicators. Moreover, no systematic comparison done for perception discrete events such as floods or erosion. This study relies on novel panel survey data approximately 1700 households residing along Jamuna River in Bangladesh well unique individual-level, satellite-based erosion data. It compares respondents’ events, namely riverbank erosion, three indicators, specifically long-term temperature changes precipitation during wet dry seasons, measurements using satellite imagery time-series (CRU TS). I find that is perceived more accurately than precipitation. Given educational attainment literacy among population are low, this indicates global increases felt even by remote who have never heard term change. Erosion strongly overestimated, especially those respondents had personally it.

Bangladesh has successfully reduced the number of deaths caused by tropical cyclones associated with storm surges in its territory. The factors responsible for this success include significant improvements satellite-based cyclone detection, early warning systems, and emergency evacuation. However, during such events, some residents prefer to not evacuate region. Based on first-hand data generated through in-depth interviews, participant observations, focus group discussions aged over 59 years, field visits, investigations, study, we provide information shelter-seeking places latest analyse reasons why do affected regions post warning. findings suggest that Bangladesh, community trust warnings increased from 56% 1991 Cyclone Gorky 96% 2020 Amphan.
