RILS協辦自然本位鄉村雙循環經濟工作坊(只有英文版本)

The Hong Kong Polytechnic University (PolyU) and China Innovative Urban-Rural Governance Research Network (CIURG) co-hosted a workshop under the theme of Nature-based Urban-Rural Dual Circular Economy on 10 March 2025.  Co-organised by several PolyU units including the Research Institute for Land and Space (RILS), the Research Centre for Nature-based Urban Infrastructure Solutions (RNUS) and the Research Institute for Sustainable Urban Development (RISUD), together with CIURG, the workshop brought together more than 50 leaders and representatives from diverse sectors, including universities, government bodies, non-government organisations and rural communities, to explore actionable strategies for promoting an urban-rural circular economy. Prof. LI Xiangdong, Dean of the Faculty of Construction and Environment, Director of RISUD, opened the workshop by emphasising the importance of a nature-based approach (NbS) in achieving sustainable and balanced urban and rural development.  The workshop included three engaging sessions that delved into topics including sustainable resource management, waste reduction, innovative land use policies, cultural heritage preservation, community empowerment, integrated urban-rural planning, and the role of technology in advancing environmental and economical practices. The sessions, each had a different sub-theme, were chaired by Prof. Ivy WONG Siu Wai, Convener of CIURG, Prof. WANG Yuhong, Director of RNUS, and Prof. DING Xiaoli, Director of RILS.  A distinguished line-up of speakers shared their insights and presentations on various topics. Featured guest speakers included: Prof. LING Kar-kan, Director of Jockey Club Design Institute for Social Innovation at PolyU; Ms XING Wenwei, Olivia, Founder of Hong Kong Urban-Rural Sustainable Development Association; Prof. TANG Man Bun, Stephen, Head of Countryside Conservation Office at the Environment and Ecology Bureau of the Hong Kong SAR Government; Ms LEUNG Kar Yee, Carrie, Chief Engineer of North Development Office at the Civil Engineering and Development Department of the Hong Kong SAR Government; Ms Kitty TAM, Programme Lead of Hong Kong 2025 from Civic Exchange; Prof. WONG Kam-sing, Former Secretary for the Environment of the Hong Kong SAR Government, and Chairman of Wu Zhi Qiao (Bridge to China) Charitable Foundation; Mr HE Yunhui, village leader from mainland China; and PolyU scholars including Prof. Ding, Prof. Ivy WONG Siu Wai, Prof. WANG Yuhong, Prof. LEU Shao-Yuan, Prof. Charles WONG Man Sing and Prof. DUAN Huan-Feng.

RILS學者應邀出席 2024 年東南亞高等院校協會會議 (只有英文版本)

At the recent 2024 ASAIHL Conference (Association of Southeast Asian Institutions of Higher Learning) held at the Universitas Airlangga, Surabaya, Indonesia on 19-22 November 2024, Prof. George Zhizhao LIU, member of RILS and Professor of LSGI, was invited to present the Hong Kong (China)’s Region/Country Report at the conference. The theme of this year’s ASAIHL conference is “University’s Role in Advancing Climate Crises Reduction.” At the conference, Prof. LIU gave an invited talk titled “AI and Satellite Remote Sensing: the State-of-the-art Technology to Map the Most Abundant Atmospheric Greenhouse Gas –– Water Vapor”, which illustrated the importance of accurate water vapor observation in the climate change and extreme weather studies and showcased the research work conducted in Prof. LIU’s Micro-Laboratory of Atmospheric Research and Geomatics Engineering (Micro-LARGE) in the field of climate change. Water vapor, as the largest greenhouse gas in the atmosphere, plays a critically important role in climate change and extreme weather events. This might be against the orthodox opinion that usually believes the carbon dioxide (CO2) is the largest greenhouse gas. Water vapor accounts for approximately 50% atmospheric greenhouse gas, depending on the weather conditions. Nevertheless, the accurate observation of water vapor is still a global technical challenge. A large number of satellites have been launched, and many have the capability to observe water vapor at different wavelength channels. Unfortunately, the water vapor data accuracy of most of these satellite sensors is low and cannot meet the requirement for climate change and extreme weather studies. Prof. LIU’s Micro-LARGE Lab insightfully pinpointed this problem and has developed different AI-based novel algorithms to significantly improve the accuracy of water vapor observations of different satellite sensors. The Association of Southeast Asian Institutions of Higher Learning (ASAIHL), founded in Bangkok, Thailand in 1956, is a non-governmental organization starting with eight state universities in Southeast Asia but now with university memberships extending to Europe, North America, Africa, and Oceania. ASAIHL’s purpose is to assist member institutions to strengthen themselves through mutual self-help and to achieve international distinction in teaching, research and public service.

土地及空間研究院學者合著研究揭示格陵蘭冰蓋夏季融水的儲存機制

土地及空間研究院核心成員、土地測量及地理資訊學系教授陳劍利教授，與國際研究團隊於《自然》期刊合作發表研究，揭示格陵蘭冰蓋內在夏季期間暫存了大量融水。   研究由南方科技大學副教授冉將軍博士領導進行。團隊首次利用定位數據來量化融水。研究員使用由格陵蘭島上數十個數據站組成的「格陵蘭全球定位系統網絡」收集所得的數據，以持續監測冰下基岩在融冰季節內不同時期的垂直位移。融水的質量是導致基岩向下移動的一個因素。團隊開發了一種創新方法，可根據融水質量來解釋偵測到的垂直移動。   格陵蘭冰蓋是目前導致全球海平面上升的最大因素。如果完全融化，有可能使平均海平面上升七米。這項研究為夏季融水在冰蓋內的移動和儲存機制提供了新視角，為應對地球上迫切的環境挑戰帶來重要發現。   閱讀更多：https://www.nature.com/articles/s41586-024-08096-3
