However, the interdependencies driving these effects are not yet fully understood. This study examines the spatial heterogeneity and dynamics of urban CI in China, focusing on the roles of land use patterns and demographic factors. Results show that despite an overall decline in urban CI, carbon inequality has worsened. Notably, previously narrowing regional disparities have now diverged, driven mainly by growing variations within regional clusters. There are significant spatial differentiation in urban CI, with northern regions exhibiting higher values compared to southern regions. The spatial integration of urban CI is strongly shaped by path dependency and lock-in effects, even amid persistent inter-regional competition. The endogenous effect of urban CI suggests that a 1 % increase in neighboring areas corresponds to at least a 0.5 % increase locally. The global regression demonstrates that urbanization, labor participation, and income positively affect urban CI, while aging, technological progress, industrial upgrading, and R&D investment negatively influence it, with both direct and spillover effects observed. Local regression analysis uncovers pronounced spatial heterogeneity, with land urbanization (accounting for 71.8 %) and population aging (60.9 %) emerging as the two most significant determinants in these relationships. These findings shed light on the need to integrate land use and demographic profiles into carbon abatement strategies, advocating for locally tailored interventions to effectively mitigate urban CI.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"181 ","pages":"Article 103689"},"PeriodicalIF":4.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The need is evident due to the escalation of flood hazards driven by sea-level rise and intensifying storm surges, the deterioration of aging infrastructure that undermines vulnerability, and the omission of shelter access in conventional risk assessments. While existing frameworks often emphasize physical exposure and hazard intensity, little is known about the integration of coastal flood risk with access to shelter in risk assessments. A bivariate spatial clustering method is employed to integrate coastal flood risk with access to shelter at the census block group level. Two findings are discerned. First, there is a mismatch between flood risk and access to shelter in coastal communities: high-risk areas tend to have limited shelter access. Of approximately 80,000 square miles exposed to high flood risk, 98 % are characterized by low shelter access, placing 17.8 million people (64 % of the population) in areas with limited emergency shelter availability. Second, racial and ethnic minorities (African Americans and Hispanics), along with mobility-vulnerable populations (the elderly and people with disabilities), are disproportionately exposed to coastal flood risks coupled with limited shelter access, particularly in Mississippi, Indiana, Texas, South Carolina, and Pennsylvania. The findings offer policy and planning guidance to support effective emergency response and resource allocation.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"181 ","pages":"Article 103686"},"PeriodicalIF":4.0,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144240298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cluster interaction occurs when a location belongs to multiple clusters at different times, indicating spatial but not temporal overlap. However, such overlap alone does not fully explain how clusters are linked or how transmission pathways form across them. Analytical frameworks to examine these dynamics remain limited. This study introduces the concept of “in-between areas”, transitional zones, that connect clusters through shared transmission routes. We propose a novel framework that integrates causal analysis with network community detection to identify clusters, detect in-between areas, and quantify their interactions. Applied to the 2014 dengue outbreak in Kaohsiung, Taiwan, the results reveal that in-between areas shift from administrative boundaries to interior districts as the epidemic progresses, indicating evolving cluster interactions. These areas link locations across different clusters, exposing the complex structure of spatial diffusion. Quantitative findings show that dominant clusters often absorb smaller ones, with the latter frequently initiating transmission into new regions. The proposed framework identifies both the timing and spatial configuration of cluster interactions, offering new insights into epidemic spread. This approach advances spatial epidemiology by supporting the design of targeted, mobility-aware public health interventions.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"181 ","pages":"Article 103688"},"PeriodicalIF":4.0,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We see an opportunity to apply the value network perspective in furthering the discourse on local development, especially in remote rural contexts where the communities depend on agriculture and allied activities. In this study, we consider the case of the emerging kiwi production sector in the Eastern Himalayan Region of India and analyze it by combining the traditional value chain and the value network perspectives. Our study is mainly based on primary data collected using different tools and techniques from various stakeholders of the kiwifruit sector in the study region. We first conduct a value chain mapping and analysis to discuss the value chain upgrading opportunities. Subsequently, we critically appraise how value (economic and non-economic) is co-created and captured in the identified value network. When juxtaposed with the linear value chain perspective, the value network perspective provided us with greater clarity on the role played by a larger set of actors and their interconnectedness in co-creating value. These actors interact in ways that lead to the development of dynamic capabilities and competencies in the network, promoting resilience and characterizing the development of the local economic system based on local interventions.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"181 ","pages":"Article 103683"},"PeriodicalIF":4.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also evaluated the variations of this coupling relationship under different human activity intensities. The results showed that HQ, WP, and CS exhibited relatively small changes during the study period, whereas SC, WY, and FP showed greater fluctuations. The coupling relationships linking ESs and SEF gradually weakened over time, with network complexity and connectivity declining. The positive contributions of HQ, CS, normalized difference vegetation index, and landscape pattern factors to network connectivity and complexity gradually diminished. In contrast, the negative contributions of SEF, including the percentage of construction land, gross domestic product, and percentage of cultivated land gradually increased. As human activity intensity increased, network connectivity and complexity showed a declining trend.
