Yet, current research lacks a well-established empirical framework operating at a disaggregated level to profile the relationship between ITAs and carbon generation. Drawing on household travel survey data for South East Queensland, Australia, this study details a frequency-distribution modelling approach that employs the Lévy distribution to characterise how carbon generation varies across ITAs. The method enhances existing carbon estimation practices beyond traditional mean-based or aggregate approaches. A seven-parameter framework derived from normal-Lévy distribution coefficients captures the relationship between travel frequency and carbon generation, enabling systematic comparison across travel modes, purposes, and household locations. The model empirically derives carbon generation thresholds (2.88 kg CO<sub>2</sub> per trip) to distinguish between intra-urban and inter-city trips, replacing administratively-defined boundaries with a data-driven spatial delineation alternative. Results reveal that while 83.5 % of trips generate relatively low carbon emission (no more than 2.88 kg per trip), these frequent, low intensity intra-urban activities constitute the majority of total carbon generation, challenging the typical conventional focus on high-emission trip reduction. This frequency-distribution approach provides urban planners and policymakers with an empirical framework for quantifying carbon impacts at the ITA level through which tailored interventions can be designed to encourage a shift to lower-carbon alternatives.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"186 ","pages":"Article 103837"},"PeriodicalIF":5.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145466812","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}

While numerous studies have investigated the balance between supply and demand for recreational service in UGS, few have employed an integrated framework that captures the non-compensatory dimensions of supply and links them to high-resolution, activity-specific demand patterns while examining socioeconomic equity. This study develops a comprehensive framework to assess UGS supply-demand mismatches using large-scale GPS trajectory data from running and cycling activities in Helsinki, Finland. We constructed a multidimensional supply index integrating availability, quality, accessibility, and morphological characteristics, which was linked to high-resolution recreational demand metrics (e.g., frequency and intensity) derived from 27,349 running and 47,866 cycling trajectories. Our results reveal three key findings: First, we identify a distinct core-periphery gradient, with urban centres facing recreational undersupply and suburban areas exhibiting oversupply. Second, a dynamic mismatch analysis reveals significant temporal variations, including a seasonal southward shift of undersupplied areas towards coastal parks in summer and a more balanced supply-demand relationship on weekends. Third, socioeconomic status significantly influences these imbalances, with 84.4 % of undersupplied “cold spots” concentrated in higher housing-price neighbourhoods, while all oversupplied “hot spots” are located in lower housing-price areas. These findings highlight the need for targeted, time-sensitive interventions addressing both spatial and temporal mismatches within their socioeconomic contexts.

Our analysis addresses both the move away from conventional or ‘traditional’ energy sources to ‘modern’ energy services, and the shift toward renewable energy technologies.

We examine the broader policy environment, focusing on the state's energy transition strategy and its implications for energy justice, spatial inequality, and economic opportunity. Particular attention is given to the role and potential of decentralized, off-grid energy systems, emphasizing the need for greater community participation in both policy design and implementation.

Horizontally, neighboring cities and intra-provincial local governments can jointly promote UGD, while enterprises operating across provincial boundaries exert negative spatial effects. These findings indicate that the impacts of different local actors on UGD vary by governance context, and that vertical-horizontal interactions function differently under diverse institutional arrangements.

This study evaluates the level of spatial access to improved water sources in Sibi and explores relevant policy implications. Spatial analysis techniques, including Kernel Density Estimation and the Generalized Two-Step Floating Catchment Area (G2SFCA) methods, are used to assess the distribution and accessibility of improved water sources across the community. Although originally developed for evaluating healthcare accessibility, the G2SFCA method proves well-suited for analyzing access to improved water sources in this context. The results reveal an uneven spatial distribution of water sources, with a higher concentration in communities’ central areas and limited availability in peripheral zones. This ratio-based disparity results in significant variation in spatial accessibility among households. The study concludes that access to improved water sources in Sibi is spatially unequal, with central households enjoying better access than those on the periphery, particularly during the dry season. These findings confirm the applicability of the G2SFCA method for spatial accessibility to improved water source assessments and highlight the need for targeted interventions.
