Bridging Research and Community: The Societal Impact of Heat Health Strategies
In recent years, the escalating effects of climate change have prompted urgent discussions on public health and urban resilience. The ongoing research led by Prof. Chao Ren from the Division of Landscape Architecture at HKU’s Faculty of Architecture exemplifies a profound engagement in the sharing of ideas and societal influence, particularly concerning heat-related health risks in urban settings.

The project, funded by the Research Grants Council (RGC), has focused on understanding the implications of extreme heat on the health of Hong Kong residents. In light of the United Nations’ Intergovernmental Panel on Climate Change (IPCC) reports, which indicate alarming temperature rises, this research is timely and crucial. The project not only highlights the urgent need for action but also serves as a model for effective knowledge transfer between academia and the community.
One of the central achievements of Prof. Ren’s research is the development of a comprehensive heat risk map. This map integrates various factors such as heat hazards, exposure levels, and vulnerability, providing a detailed spatial-temporal analysis of heat risks across Hong Kong. The findings reveal that urban heat islands exacerbate health issues, with mortality risks significantly higher in areas lacking sufficient cooling facilities. This data is instrumental for policymakers and health officials, facilitating informed decision-making to mitigate heat risks.
Through collaboration with the Hong Kong Observatory and the Hong Kong Red Cross, the project has fostered an exchange of knowledge that extends beyond academic circles. The Hong Kong Observatory has updated their extreme hot weather warning system by incorporating a new prolonged heat warning and related weather services. Workshops have been organised to educate social workers and government officials about the health implications of heatwaves. These initiatives not only raise awareness but also empower communities to adapt to changing climatic conditions. By translating complex research findings into actionable insights, the project exemplifies the vital importance of information sharing in improving the community.
Likewise, the partnership with the Hong Kong Red Cross has proven invaluable. It has enabled the dissemination of crucial information regarding heatwave trends and their effects on vulnerable populations. For instance, the Red Cross has leveraged data from the project to conduct heat resilience activities for over 1,000 outdoor workers in high-risk areas. This proactive approach demonstrates how scientific research can directly inform community practices, ultimately saving lives and improving public health outcomes.
The societal impact of Prof. Ren’s work extends beyond Hong Kong. Her expertise has garnered international recognition; she has been invited to contribute to the development of guidelines by the World Meteorological Organisation and to join the Steering Committee of the Global Heat-Health Information Network. This global perspective enriches local initiatives and amplifies the significance of the research on an international scale.
The RIF project, completed in June 2023, emphasises sustainable building design and innovation. It aligns closely with Prof. Ren's research on green building technologies, aiming to promote environmentally friendly construction methods. The project received a Merit Award in the Research and Planning category at the Green Building Award 2023, co-organised by the Hong Kong Green Building Council and the Professional Green Building Council, highlighting its significant impact on sustainable architecture. It also demonstrates the value of interdisciplinary collaboration in tackling urgent societal issues. Beyond academic contributions, the project provides practical solutions that meet community needs.
In conclusion, the heat health initiative led by Prof. Ren exemplifies how rigorous research can foster societal progress and impact. By bridging the gap between academia and community practice, this project not only addresses immediate health concerns but also lays the groundwork for sustainable urban resilience in the face of climate change. As cities worldwide grapple with similar challenges, the lessons learned from this initiative could serve as a blueprint for future efforts in community development.
