Abstract This study aims to analyze the spatiotemporal evolutionary characteristics of global terrorism from 1970 2020, providing a comprehensive understanding its dynamics and patterns. The research seeks fill gaps in existing literature by integrating geographic perspectives methods enhance terrorism's spatial temporal dimensions. employs multi‐methodological approach, combining Mann–Kendall trend test, autocorrelation analysis, kernel density estimation, standard deviational ellipse. These are applied data 176 countries, covering 171,327 terrorist incidents recorded Global Terrorism Database (GTD) 2020. Pertinent findings as follows. Temporally, risk has evolved significantly over past five decades involves four distinct stages, i.e., emerging stage (1970–1991), descending (1992–2000), rampant (2001–2014), attenuating (2015–2020). Meanwhile, 117 countries show an increasing trend, 56 decreasing risk. Spatially, distribution is characterized clustering aggregation, with constant shift gravity center dominant direction.

Ecosystem service value (ESV) reflects ecosystem functions and benefits; however, the factors influencing ESV mechanisms driving it in wetlands non-wetlands are not yet fully understood. The Yellow River Delta (YRD) is distinguished by presence of numerous wetland areas that both Reserve non-Reserve thus was selected as designated study area. In this study, spatiotemporal structures YRD between 2000 2020 were studied using land cover change analysis equivalent factor methodology. addition, we analyzed drivers behind geographical variability applying Geographical Detector method. results showed structure National Nature relatively stable, whereas area exhibited greater fluctuations; is, decreased 11.43% compared with more stable areas, where 4.93%. Furthermore, disparities distribution use types gave rise to a discernible spatial overall ESV, northeast exhibiting significantly higher levels southwest. Additionally, past two decades, center gravity regions has shifted towards urban centers, have migrated coastline. Normalized Difference Vegetation Index identified main driver heterogeneity. findings highly relevant regional ecological conservation promotion economic social development.

This study employed a phronetic (practical wisdom) analytic framework to explore the Tehran, Iran, City Council’s Article 5 Commission’s land use decisions from 1999 2024. We argue that, during that period, Commission nominally embraced practical wisdom in lieu of episteme or techne as arbiter its choice making. Nonetheless, those years, members disproportionately granted change permits Tehran Comprehensive Plan principally benefited city’s upper class. Our central finding underscores role advancing elite rather than broader public interest needs. conclude even planning process can fall prey willfully undemocratic In this case, occurred when discretionary powers delegated serve were instead routinely interests an elite. analysis highlights urgent need for more ethical, popularly accountable, and equitable practices general population Tehran.

This study investigates the evolving landscape of urban livability research through a bibliometric analysis, addressing key questions such as development thematic clusters and identification emerging trends in field. Using advanced tools like VOSviewer bibliometrics R-package, we analyzed data from Web Science to uncover significant focus areas, influential authors, collaboration networks. The findings reveal marked increase publications since 2011, highlighting growing academic interest this area. We identified four major clusters—Motor Themes, Niche Emerging or Declining Basic Themes—that provide structured understanding also emphasizes prominent role countries United States China advancing research. Additionally, concepts “resilience” are highlighted areas for future exploration. offers valuable insights scholars, policymakers, planners, guiding investigations contributing ongoing discourse on livability.
