Many large-scale CCS deployments are expected to be cross-border projects, posing specific questions in local communities. These questions may relate to the perceived lack of local benefits, why local emissions are not prioritized, and the feeling that each country should deal with its own emissions. We used qualitative research methods, including a thematic analysis of interviews and newspaper articles, to study local perceptions of the Coda Terminal project in Iceland, which is set to become one of the first international CCS hubs. Our results show that the project was depicted as an innovative solution to a global problem, with little impact at its implementation site. At the same time, the innovative nature of the project raised concerns about its scale, the associated risks, and the perception that it imports “waste” from other countries. Concerns have been heightened by the perceived marginalization of opposing voices, including those opposed to importing CO₂. We observed that opportunities to have a productive conversation on the import were obstructed by actors focusing on the correct definition of CO₂ instead of listening to and understanding people’s framings. We provide insights on how thinking about the why, who, and when of technology-tailored public participation can improve the dialogue around cross-border CCS.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"94 ","pages":"Article 103048"},"PeriodicalIF":9.1,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144925252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Drawing on postcolonial theories of island laboratories, this paper scrutinises DSM and the scramble for minerals by corporations, states, and state groupings. First, through a review of literature, the paper critically examines arguments for DSM that position it as a pathway towards just transition, including through purported benefits to nations in the Pacific Islands Region. Next, drawing on primary data collected during 2023–24 including interviews with Pacific Island climate activists (n = 45), it highlights activist understandings of DSM as perpetuating historic and ongoing colonialism, extractivism, and experimentation in the Pacific Islands Region. Far from a standalone issue, Pacific activists draw on principles of decolonisation and self-determination to engage with the intersecting crises of climate change, extractivism, and to resist DSM. Using DSM as a case study, this paper contends that the plight faced by Pacific Peoples due to the climate crisis, has been weaponised to justice wash extractivism as a climate solution.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"94 ","pages":"Article 103053"},"PeriodicalIF":9.1,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144931615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

However, most research focuses on immediate displacement, limiting our ability to understand the long-term consequences of extreme weather events on residential mobility. To address this gap, this study establishes the relationships between home damage caused by bushfires, floods, and cyclones and ensuing residential mobility in the following five years. Using nationally representative individual-level data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey from 2009 to 2023, we use finite distributed lag logistic models to determine the level, timing, and direction of weather-induced mobility, distinguishing between onward and return movement and distance moved. While most moves occur in the immediate aftermath of an extreme weather event, results indicate that weather-induced home damage increases the odds of moving for up to three years. Four distinct mobility patterns emerge: (1) <em>immediate relocation</em>, which brings some moves forward, (2) <em>delayed displacement</em> up to three years later, particularly over short distances, (3) <em>short-term displacement</em> followed by return, and (4) <em>repeat onward migration</em>. Younger adults and renters are more likely to be involved in all mobility types. Tertiary-educated individuals are less likely to return, but more likely to move repeatedly, while separated individuals are more likely to be delayed movers. The diversity of mobility responses underscores the conceptual and methodological complexities of estimating weather-induced population movement and the need for nuance and caution, while showing the benefits of distributed lag models to capture time dynamics. Our findings also highlight the need for targeted support mechanisms that account for different mobility trajectories and varying constraints faced by sub-population groups in the aftermath of extreme weather events.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"94 ","pages":"Article 103050"},"PeriodicalIF":9.1,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144925253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

This study brings into view the perspectives of those not typically at the decision-making table. We build from previous projects collecting the “lived experiences” that aim to lift-up diverse voices from local communities. Our approach uses original semi-structured interviews (N = 24), focus groups (six with N = 45 total participants), participant observation in England, Scotland and Wales coupled with local surveys in three clusters (n = 600) and nationally representative survey data (N = 1,178 respondents), all of which were conducted from June 2022 – November 2024. We identify five themes arising from these data: place-based perceptions and local identities, potent lived experiences of injustice, technology-specific concerns, issues of trust and awareness, and issues concerning policy and governance. We then discuss these five themes considering recent literature on recognition justice and sense of place, procedural justice and community engagement, and distributive justice and localising benefits. The resulting evidence provides insight as to how net-zero industrial transitions are perceived by local communities, and data from the national survey allows us to show how local perspectives align and resonate with UK publics on a national scale.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"94 ","pages":"Article 103051"},"PeriodicalIF":9.1,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144896681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

This study integrated random forest techniques and 264,302 daily bank transaction data from 271 Chinese cities (2017–2019) to simulate household medical expenditure responses to climate change. To observe the heterogeneity among different cities, cities are categorized into 14 city groups based on their historical temperature and economic conditions to build simulation models. We further projected the future household medical expenditures in different cities under four Shared Socio-economic Pathways (SSPs), considering the pure effects of climate change and sensitivity changes under SSP-informed socioeconomic and physiological scenarios. We find that households in higher-income cities and cities with historically low temperatures have enhanced resilience to heat and cold, respectively. Climate change is projected to slightly decrease household medical expenses in China by 5.2% (SSP126) to 5.6% (SSP585) in 2060, attributed to fewer cold-related medical expenditures. Under the physiological scenarios, enhanced body system functions are projected to reduce medical expenditures by 19.5% (SSP245) to 27.6% (SSP585) by 2060. Rising incomes under socioeconomic scenarios may stimulate healthcare demand and drive expenditures up by 4.9% (SSP370) to 22.5% (SSP585).

Drawing on over two years of ethnographic fieldwork including participant observation and interviews, I explore this question in the particular geographic and land use context of the Poudre Canyon in northern Colorado. Local stewardship practices in mountain communities can benefit populations beyond the fire perimeter. These may be rooted in ongoing relationships to the land, local, volunteer-based hazard mitigation and emergency response, and post-fire collaborative efforts. Using narrative analysis, I examine how landscapes at risk of fire are defined, how wildfire risk is communicated to those living in these landscapes in Colorado, and how discourses of risk and responsibility facilitate or constrain adaptation to living with extreme fire. I encourage an approach to risk communication that conceptualizes those who live in fire adapted landscapes as potential stewards. I also suggest that wildfire risk reduction efforts should be more geographically and socially expansive, to acknowledge that contending with wildfire and its associated hazards of smoke and flooding is a society-wide challenge, not just for those living in fire adapted landscapes. Living with fire is a process, and community members, practitioners, and scientists alike are reorienting toward a world with more extreme wildfire.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"94 ","pages":"Article 103047"},"PeriodicalIF":9.1,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144841633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

These policies often rely on the “blue transitions” theory of change, which posits that an expansion of aquaculture will aid in recovering declining fish stocks and enhancing livelihoods. However, the blue transitions theory is relatively new, leaving many aspects uncertain, especially regarding how transition stages unfold and impact communities as they are expected to transform livelihoods. Frequently, these policies adopt a top-down approach driven by political and corporate interests at global or national levels, emphasizing environmental and economic benefits while neglecting local social, cultural, and historical contexts. This study aims to identify gaps in current blue transition policies at the local level through two empirical case studies in Baja California Sur, Mexico. Additionally, it evaluates the suitability of existing frameworks for incorporating justice in food system transitions for seafood system transitions and provides insights for developing more equitable blue food policies. Using an exploratory mixed methods approach from 2021 to 2023, including ethnography, interviews, surveys, and focus groups, this research delves into the complexities of aquaculture policies for communities going through blue transitions. Findings indicate that these policies often prioritize economic development over social, cultural, and historical considerations, leading to injustices within communities. The case studies reveal impacts and challenges such as intra-community conflict, illegal fishing, and threats to food security and resilience, as well as benefits like momentary economic gains. Applying a framework for just food system transitions, we advocate for flexible, community-centric policies that recognize local heterogeneity and empower communities to shape their transitions, including deciding whether a transition is appropriate. This study underscores the limitations of viewing aquaculture as a panacea for small-scale fisheries’ challenges, emphasizing the need for holistic, multiscale management approaches. Contextualizing blue transitions within local realities and prioritizing food justice can promote just and equitable outcomes that address the nuanced needs of diverse coastal communities amidst global pressures.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"94 ","pages":"Article 103046"},"PeriodicalIF":9.1,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144831584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

The Gaza Strip exemplifies such a context, where the intersection of warfare, urban density, and environmental vulnerability demands urgent scientific inquiry. This study aims to assess the environmental impact of the 2023–2024 war on air quality in the Gaza Strip by examining temporal and spatial changes in key atmospheric pollutants. We use daily observations of five pollutants, nitrogen dioxide (NO₂), sulfur dioxide (SO₂), carbon monoxide (CO), methane (CH₄), and the ultraviolet aerosol index (UVAI), obtained from the Sentinel-5P TROPOspheric monitoring instrument (TROPOMI) satellite and combine these with meteorological data (temperature, humidity, wind speed, and precipitation) to explore their behavior before and during the conflict. Our methodology integrates time-series analysis with statistical and machine learning models, including SARIMAX, Holt-Winters, Random Forest, and XGBoost, to forecast pollutant concentrations based on pre-war conditions and identify deviations post-October 2023. The findings reveal distinct responses to pollutants during the war. UVAI and CO showed sharp and sustained increases linked to widespread combustion and infrastructure damage, while CH₄ concentrations exhibited a steady rise associated with the collapse of waste management. SO₂ displayed episodic spikes, likely tied to fuel depot destruction and generator use, whereas NO₂ trends showed temporary suppression due to mobility restrictions and reduced industrial activity. Our findings demonstrate that traditional forecasting models may require adaptation to conflict-specific conditions, given altered emission sources and rapid pollutant dispersal in a small geographic area like Gaza. Policy implications include the urgent need for conflict-sensitive environmental monitoring systems, the integration of satellite data into humanitarian planning, and the development of adaptive forecasting models that incorporate war-related variables, such as infrastructure damage and displacement patterns.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"94 ","pages":"Article 103044"},"PeriodicalIF":9.1,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144831583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Yet, as climate change is increasingly invoked to justify coercive environmentalism, the political consequences of this emerging paradigm remain underexamined. The perceived effectiveness of authoritarian regimes, such as China, in addressing ecological crises is contributing to a shift from participatory to coercive approaches. This trend not only raises the risk of democratic backsliding but also poses concerns about implications for political legitimacy. This paper examines the relationship between coercive governance, environmental crisis management, and political legitimacy. It uses field surveys and interviews to assess how the 2015 deployment of soldiers to enforce fisheries regulations influences support for regime institutions and evaluations of regime performance. The findings show that the militarized policy undermines legitimacy, as indicated by both the widespread opposition it generates and the negative assessments of government, stemming from heightened social inequalities—within and between communities—and reduced community involvement in fisheries management. Additionally, while many participants perceive improved fisheries protection, this does not equate to enhanced legitimacy, as these perceptions do not translate into support for the policy or the government overall. Instead, increased conflict—both between fishers and soldiers, and among the fishers themselves—along with reports of heightened personal insecurity, further suggests that the policy undermines legitimacy. This evidence of failure to secure widespread legitimacy implies that, for long-term sustainability, coercive measures must eventually give way to strategies that foster communal ownership and active participation.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"94 ","pages":"Article 103045"},"PeriodicalIF":9.1,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144827462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
