Social vulnerability indices are often used to quantify differential the impacts of climate change within coastal communities. In this review, we examine how “tried and tested” methodologies for analysing social hazards at coast being challenged by a new wave that offer more nuanced conclusions about who is vulnerable, how, why. Instead producing high-level, generalised, static vulnerability, engages deeply with interlinked socioeconomic, cultural, political, economic specificities place, as well multi-scalar temporal dynamics, incongruities, inconsistencies inherent peoples’ lived, felt experiences vulnerability. By integrating these complex observations into an output still readily accessible decision- policy-makers, supports pursuit tailored, context-appropriate, equitable adaptation. We suggest one way forms analyses might be operationalised, reflecting on experimental research project uses personas or fictional characters in Aotearoa New Zealand.

Large and intense wildfires are an integral part of many Canadian landscapes, playing a critical role in ecosystem dynamics. However, the recent catastrophic fire seasons have highlighted threat that can pose to human communities. Identifying areas at higher risk is therefore crucial order mitigate impacts on society. This study presents standardized method for nationwide wildfire assessment, focusing buildings populations. Using Burn-P3 simulation model, along with building footprint census data, we generated hazard, vulnerability, maps Canada's forested regions. Our findings demonstrate nuanced understanding when considering interaction between hazard physical vulnerability. Approximately 32.3% 6.3% land classified as High Very high risk, respectively. We estimate 111,519 units (5.8%) directly exposed 10,622 (0.6%) risk. Moreover, found approximately 283,200 people reside while 30,500 live Indigenous on-reserve communities particularly vulnerable impact. 18.9% living reserves fire, compared only 2.4% non-reserve population. The present offers information development national management policy provides new insights support implementation effective measures reduction.

Abstract Climate change is leading to more extreme weather hazards, forcing human populations be displaced. We employ explainable machine learning techniques model and understand internal displacement flows patterns from observational data alone. For this purpose, a large, harmonized, global database of disaster-induced movements in the presence floods, storms, landslides during 2016–2021 presented. account for environmental, societal, economic factors predict number displaced persons per event affected regions. Here we show that displacements can primarily attributed combination poor household conditions intense precipitation, as revealed through interpretation trained models using both Shapley values causality-based methods. hence provide empirical evidence differential or uneven vulnerability exists means its quantification, which could help advance evidence-based mitigation adaptation planning efforts.

This study constructed a Multi-Dimensional Flood Risk Assessment (MDFRA) framework combining comprehensive index system, an integrated weight method, and clustering algorithm assess flood risk Basin. We first system including eight hazard indexes, four exposure vulnerability indexes demographic, economic, ecological, infrastructural categories risk. weights were determined by which Shapley value Analytic Hierarchy Process method (SAHP). Finally, possibilistic fuzzy C-means was employed identify levels. MDFRA presents realistically comprehensively, revealing composition providing more detailed information. Results show that high-risk regions accounted for 34.51% basin area mainly concentrated mid-lower reaches, while middle-risk (19.13%) middle-high-risk (23.35%) distributed upstream. 4.52%, 5.12%, 13.37% assigned as very-low, low, middle-low respectively, adjacent Danjiangkou reservoir.
