Abstract Due to the pervasive uncertainty in human society, super large and megacities are increasingly prone becoming high‐risk areas. However, construction of urban resilience this new era lacks sufficient research on core conditions complex interactive mechanisms governing it. Hence, study proposes a specialized event‐oriented framework for China based pressure‐state‐response (PSR) theory. We examined COVID‐19 cases 30 cities across analyzed distribution prevention control achievements between high‐level non‐high‐level conditions. Our findings reveal following key points: (1) High‐level rely three condition configurations: non‐pressure‐responsive type, pressure‐state pressure‐responsive type. (2) High economic may indicate robust state systems amid demographic pressures. In experiencing fewer event pressure factors, application digital technology plays crucial role daily management. (3) The implementation flexible policies proves beneficial mitigating impact objective conditions, such as environmental resilience.

Going beyond traditional silos, the Resource Nexus approach has potential to achieve sustainable resource management by maximizing synergy and minimizing trade-offs in planning management. This review addresses four main research questions: (i) How concept advanced recent years? (ii) What are advancements assessment methods tools? (iii) practices opportunities ? (iv) pathways for harnessing those opportunities? Our findings, based on a systematic of 203 articles, reveal that is evolving with new components such as land, pollution (i.e. negative resource), climate change, addition like water, energy, food. The field been enriched over years advancement knowledge development tools Nexus. However, application real-world scenarios still limited these models lack ability fully capture complex interconnected nature Nexus, which necessitates further efforts realize its full potential. Addressing challenges, we propose conceptual framework operationalization identifies three key areas: developing comprehensive yet flexible assessment, bridging data gap, creating nexus-informed society within supportive policy regulatory environment monitoring, evaluation, accountability learning mechanisms place.

The Lijiang River Basin in southwest China. This research focuses on the structure, function, and evolution of water metabolic system. It quantifies multiple processes involve cycle, considering natural social influences. Furthermore, an integrated metabolism network system is established, ecological analysis introduced to quantitatively simulate circulation analyze interaction between components during 2010 2020. results contribute a deeper understanding nature, state, stability metabolism. basin balanced, with moderate robustness high efficiency. structure unchanged, little fluctuation flow transmission, revealing development Basin. surface compartment (more than 80% total) contributes most significantly processes, abundant inflow. Water consumption mainly driven by agricultural irrigation compartment. relationships among pairwise compartments are mutualistic synergistic, indicating healthy process. Exploitation being exploited dominant types. These insights reveal how quantified, can be further optimized improving
