Given the distinct vulnerabilities to heat exposure between urban and rural populations, we project future changes in summer heatwave exposure and assess urban–rural exposure inequity throughout 2021–2100 under SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios across 18 Asian countries. Results suggest substantial exposure increases in the future against the baseline, primarily driven by climate change. With ongoing urbanization, urban–rural exposure inequity will continuously rise, with India and China emerging as the hardest-hit countries. Generally, urban and rural population exposures tend to increase in the future, whereas urban will contribute 76 % of the total growth on average during 2021–2060 and 90 % during 2061–2100. This inequity can be largely derived from the disparity in urban–rural compounding effects induced by simultaneous changes in climate and population. Furthermore, a novel normalized index is developed to potentially indicate the relative need for developing and implementing future country-level heatwave adaptation measures between urban and rural. Our findings highlight the necessity for tailored adaptation strategies for individual countries, prioritizing the urban for China, Japan, South Korea, North Korea, and Malaysia, and equal emphasis placed on implementing heatwave adaptation measures in rural as in urban for Mongolia, as well as Nepal, Bangladesh, and Cambodia under SSP2-4.5. Additionally, incorporating age structures reveals that future population aging will narrow the urban–rural adaptation needs for elderly (60+) adults while widening those for younger (<60) adults. We also emphasize the uncertainty of future exposure changes and their urban–rural inequity, which should be considered for decision-making. Our findings can inform future country-level planning of targeted heatwave adaptations in both urban and rural to cope with continuously increasing heatwave risks. The proposed method can also help assess future exposure inequity to other climate risks between urban and rural populations, which is critical for prioritizing resources and promoting equity in urban–rural climate adaptation policy.</div></div>","PeriodicalId":54226,"journal":{"name":"Climate Risk Management","volume":"51 ","pages":"Article 100777"},"PeriodicalIF":5.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145791424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Findings reveal that relocation has catalysed into diverse wellbeing outcomes for different population groups. While relocated individuals report enhanced physical safety, they also face emotional and psychological hardships, as do those who didn’t relocate.

This division is experienced by not only those who live at the old site, and those living at the new site, but also newcomers to Grantham. Additionally, an experienced absence of essential community infrastructure, such as social hubs and transport services, has hindered the integration of relocated individuals and newcomers, further impacting broader wellbeing.

Transformational efforts are increasingly advocated to overcome limits to climate change adaptation, but they can entail difficult and potentially disruptive decisions that depend on the goals that individuals and societies decide to pursue, and thus on the values they wish to prioritise, reconfigure or leave behind in response to radical changes. The call for transformational adaptation revives the impetus for placing values centre stage but also poses key challenges for adaptation research and practice. This perspective outlines three challenges for taking values seriously: understanding what values are, by acknowledging both their descriptive and normative dimensions; accounting for the multiplicity of value holders across space and time; and designing processes through which value conflicts are made explicit and can be legitimately resolved. We outline how ethics can help in determining the relation between what people <em>find valuable</em> and normatively well-grounded values; propose ‘value mapping’ exercises to elicit the values of actors involved in the adaptation process; and stress the potential of deliberative approaches in supporting efforts for more transformative adaptation. These challenges are exemplified through planned relocation, a radical and potentially transformative adaptation response. This paper outlines the distinction between descriptive and normative conceptions of values, a distinction often overlooked in environmental social sciences, and demonstrates its significance for addressing the multiplicity of values and conflicts in transformational adaptation. Rather than prescribing a definitive method for closing the gap between these descriptive and normative conceptions on values, it traces an initial pathway for integrating empirical and ethical perspectives and calls for renewed collaborations across the social sciences and humanities to advance values-based adaptation research and practice.</div></div>","PeriodicalId":54226,"journal":{"name":"Climate Risk Management","volume":"51 ","pages":"Article 100791"},"PeriodicalIF":5.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146077498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Projected flood scenarios (2050 and 2080) indicate significant increases in inundation extents and exposed populations and economic assets, particularly under combined SLR + VLM scenarios. The Yangtze Delta shows the highest economic exposure (up to approximately 1 trillion USD), whereas the GBM Delta exhibits the greatest demographic vulnerability, potentially affecting approximately 20 million individuals. The relative contributions analysis emphasizes an increasing dominance of SLR over time, especially under high-emission scenarios.

Most respondents perceived themselves as “very much” vulnerable to heat (C: 55%, H: 39%), primarily due to health impacts and inadequate housing and work conditions contributing to high exposure.
