What constitutes a large fire event in each territory varies regionally depending on biophysical attributes and fire management response. Despite the efforts made to provide standardized metrics across ecosystems, there remains a need for new methods to identify and evaluate fires that are contextually large. Here, we propose a framework to evaluate contextually large fires in Europe, considering them as fires larger than expected based on return period functions. Utilizing 23 years of data from the European Forest Fires Information System, we applied extreme value theory to compute fire return periods at the regional level (administrative units of approximately 17,600 km2). Results identified 115 regions out of 330 (35%) that experienced at least one contextually large fire, primarily in southern Europe, but also dispersed across the temperate and Atlantic biomes. While 32 contextually large fires were larger than 10,000 ha, 104 were smaller than 500 ha. The occurrence of contextually large fires shows a positive trend along the study period. This dataset provided valuable insights for assessing extreme wildfires, their distribution and their probabilities, facilitating effective risk mitigation strategies in Europe.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"176 ","pages":"Article 103539"},"PeriodicalIF":4.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143346340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A location showing appreciable anthropogenic change is the middle Amite River and floodplain in southeastern Louisiana. Because of regional demand for construction and lack of other aggregate resources, gravel and sand mining began in the 1930s and has generally increased over the past century. Countless geomorphological alterations have occurred, including the creation of pits and ponds of diverse sizes and shapes. In this paper, we employed numerical methods to analyze changes in mining topology within the Middle Amite floodplain. Specifically, we utilized the Level Set Method (LSM), a numerical approach developed by Osher and Sethian in 1998, to assess surface curvature and shape. Additionally, the Localized Contour Tree (LCT) was applied to delineate mining depressions. Using LiDAR DEMs from 2005 to 2018, in a floodplain area of 9.6 km², the results indicate a marked increase in the number of pit depressions, rising from 163 to 289 and expanding of the depressions total area from 845.6 ha to 952.3 ha, with the most substantial growth observed in Reach D. , with notably, increase in the mean elevation ranges, particularly in Reach B, which saw depths grow from 1.3 m to 4.23 m. However, the volume storage showed an overall decline from ∼28.6 million m³ to ∼26.7 million m³, driven largely by a significant reduction in Reach E. The decrease in the storage capacities could be explained by the filling of the sedimentation of the pits over time, changes in the mining practices that may involve intentionally reducing pit volume capacity, other interactions within the floodplain environment such as pit captures contributing to the observed decrease in volume storage, or water level changes between the LiDAR imagery. implications of this study include the massive anthropogenic change in 13 years and decreases in floodplain water storage capacity, emphasizing the need for adaptive flood management strategies. These findings also provide practical guidance for environmental management and policy formulation, as the current state sand and gravel mining BMPs and buffer zones were inadequate to prevent pit captures the potential application of these methods elsewhere.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"175 ","pages":"Article 103491"},"PeriodicalIF":4.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143229627","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}

Our framework allows for a more nuanced assessment by selecting regionally aligned indicators, establishing clear benchmarks, and evaluating SDG performance across multiple dimensions. A key finding is the necessity of utilizing at least three distinct indicators to capture the complexity of each SDG. Moreover, our approach—combining average targets with regional equity considerations—produces more consistent and meaningful results for local governance. By 2015, China's provincial SDG implementation surpassed key milestones, but regressions were observed in SDG12 (responsible consumption and production), SDG13 (climate action), SDG14 (life below water), and SDG15 (life on land), underscoring the need for renewed efforts.

The differences-in-differences (DID) model was used to assess the recovery in economic volume (EV) and economic growth rate (EGR). Then, the ‘leave-one-out’ method was used to analyze individual city responses, and the random forest (RF) algorithm was employed to identify the key demographic and economic factors driving the recovery of economic activities. Results showed that despite incomplete recovery in EV (−2.7%) and EGR (−8.2%), there were notable positive time-varying spillover effects with a 47% increase in EV and a 41% increase in EGR. Meanwhile, the recovery trajectories exhibited an inverted \"N\" shape, reflecting a rebound pattern during the pandemic. Overall, relatively positive trends in EV recovery occurred primarily in East China, while variability in EGR responses across individual cities remained relatively insignificant.
