Previous research has primarily assessed water security in contexts with and without the presence of ES flows, but further research is necessary to understand the influence of water yield inflow(WY_inflow) and total nitrogen inflow(TN_inflow) as critical determinants of water security. To address dynamic water security assessment and its driving mechanisms, we developed a novel water security index (WSI) that incorporates water quality and ES flows. Additionally, we employed a spatial Durbin model to investigate the impact and spatial effects of related factors on water security, applying it to the Yiluo River Watershed in China. The results revealed that: 1) the dynamic WSI of sub-watersheds incorporating ES flows was an improvement over the static WSI; 2) precipitation and the proportion of cropland significantly positively impacted static WSI, but their impact on dynamic WSI was not significant; 3) WY_inflow intensity contributed positively to dynamic WSI, while TN_inflow intensity negatively influenced dynamic WSI; and 4) most determinants of water security, including WY_inflow and TN_inflow intensity, exhibited negligible spatial spillover effects. Notably, the contribution of ES flows to water security showed an upward trend, accounting for approximately 30% by 2018. Such insights are crucial for formulating sustainable management strategies, such as ecological compensation, to enhance long-term regional water security.</p></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"172 ","pages":"Article 103421"},"PeriodicalIF":4.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142241523","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}

Employing an urban-rural gradient (URG) approach, we investigate built-up land dynamics across six representative emerging GSMs spanning 1985–2020, contextualizing our findings within urbanization theory and sustainable development discourse. Our analysis reveals that urban center growth and peri-urbanization drive a substantial proportion of built-up land expansion (36.47% and 27.39%, respectively), in contrast to the minimal increases observed in rural clusters and semi-dense areas (2.48% and 2.44%, respectively). The predominant expansion mode is sprawling growth, notably evident in peripheral areas, while densifying growth is mainly confined to urban centers and mostly uninhabited areas. Sprawling shrinkage is observed in dense and semi-dense urban areas, as well as rural clusters. These nuanced dynamics illustrate the varied ways in which regional territories engage with and are shaped by the urbanization process. Through the lens of the URG analysis, our study enhances understanding of spatial transformations in the GSMs, offering informative insights for fostering sustainable cities and human settlements.</p></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"172 ","pages":"Article 103419"},"PeriodicalIF":4.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142241525","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}

To fill this research gap, this paper explores whether accessibility is in accordance with satisfaction with daily commute (SWDC), and the dominant factors influencing SWDC in different time periods. Given the important objective role of accessibility, this paper used 1512 valid questionnaire data and API traffic big data from Xi'an, China, and employed the Satisfaction with Travel Scale (STS) covering three domains, and hierarchical regression methods to calculate the cumulative opportunity accessibility for four transport modes (walking, cycling, car, and public transport [PT]). The results show that the accessibility of the four transport modes was consistent with SWDC within 20-min. There were significant changes in car and PT within 40- and 60-min traffic circles; however, accessibility and SWDC results for these two modes were inconsistent. Furthermore, we found that travel attitude had the greatest impact on SWDC for walking and cycling within 20 min. Analysis of SWDC for car and PT in three time periods (i.e., 20 min, 20–40 min, and 40–60 min) showed that SWDC with car travel was only significantly affected by the built environment within 20–40 min, whereas travel characteristics played a dominant role in the other two time periods. For PT, SWDC was most affected by built environment, travel characteristics, and travel-related attitude.</p></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"172 ","pages":"Article 103417"},"PeriodicalIF":4.0,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142241524","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}

A major limitation of the RF model is its inability to quantify the uncertainties associated with the predicted populations, which can be important for policy decisions. In this study, we applied a Bayesian Additive Regression Tree (BART) model for population disaggregation and compared the result with a RF model using both simulated data and the 2021 census data for Ghana. The BART model consistently outperforms the RF model in out-of-sample predictions for all metrics, such as bias, mean squared error (MSE), and root mean squared error (RMSE). The BART model also addresses the limitations of the RF model by providing uncertainty estimates around the predicted population, which is often lacking with the RF model.
