The Loss of Urban Resilience is Consistent with the Decline of Sustainability
Sustainability and resilience are ambiguously used in theory and practices, and have not so far connected with each other clearly. This study attempts to clarify whether the transformation of specified resilience is consistent with urban sustainability. Here, urban sustainability is operationalized with the variations of multifaceted biophysical properties at temporal scale, and urban resilience is characterized by different levels of waterlogging. Results show that the waterlogging resilience appears strong spatial aggregation both at watershed scale and from waterlogging points perspectives. Meanwhile, the examined urban system is dominated by a series of negative feedbacks including the deterioration of soil retention, unstable ecological security, climate warming, and intensified precipitation. When the sustainability is aligned with waterlogging resilience, we find most indicators decrease rapidly as approaching to waterlogging points and remain stable when the distance is beyond 1.6 km. It is suggested that the surroundings where the distance from waterlogging points is within 1.6 km should be tailored for urban adaptive management. Our findings provide novel empirical insights for better understanding the relationship of sustainability and resilience by showing that the declining of urban properties is spatially coincident with the transformation of resilience and further presents threshold effect
