Evaluation of the vulnerability to public health events in the Guangdong-Hong Kong-Macao Greater Bay Area

Abstract

With the continuous improvement in the integration of urban agglomeration, a multi-functional, socialized, and complex dynamic system, effective prevention and control of emergent public health events have become increasingly important. Based on the Public-Health Vulnerability-Assessment-System of Urban Agglomeration (PVUA), the temporal and spatial differentiation characteristics of vulnerability in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) for the period of 2015-2019 are explored, and the vulnerable cities to public health events are identified in this area. The results can be summarized as follows: (1) The overall vulnerability to public health events in GBA decreases in the investigated period. (2) In the temporal dimension, accompanied by social and economic development, the sensitivity to public health events increases in GBA, and the coping capacity change from stable fluctuation to rapid improvement. (3) From the spatial dimension, the sensitivity level in GBA is low in the west, relatively high in the middle, and high in the southeast; the coping capacity is high in the southeast and low in the northwest; the collaborative governance capacity presents a spatial pattern of being low in the south and high in the north. (4) In the period of study, the vulnerability to public health events in Guangzhou and Jiangmen is stable at the lowest level, while that in Zhaoqing, Foshan, and Hong Kong SAR (Special Administrative Region) gradually reduces; the vulnerability in Shenzhen, Zhuhai, and Dongguan is fluctuating, and that in Huizhou, Zhongshan, and Macao SAR is continually maintained at a higher and the highest level.

Designing for the post-pandemic era: Trends, focuses, and strategies learned from architectural competitions based on a text analysis

“…Thus, public health issues have major impacts on urban planning, design, and development, and the related crises have resulted in the restructuring and optimization of urban spaces ( 13 ). These historical experiences of integrating the built environment and public health fully demonstrate that urban design is an integral factor in improving public health ( 14 , 15 ) and plays a critical role in the prevention of disease outbreaks; the control, isolation, and mitigation of pandemics; and the formulation of countermeasures after such events ( 16 ).…”
