土地及空間研究院共同舉辦可持續城市發展與生態保護研討會 (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 Sustainable Urban Development and Ecological Conservation on 2 April 2025.  The workshop took place in the Mai Po Nature Reserve, a wetland listed as a “Ramsar site” for its international importance. Located in Yuen Long, the Mai Po Nature Reserve is hailed as paradise for migratory birds, providing diverse habitats such as gei wai, mangroves, intertidal mudflats, reedbeds and many more to local wildlife species including waterbirds, aquatic fauna and insects.  The sanctuary is facing ecological challenges as the Northern Metropolis project includes filling fish ponds and removing woodland in the Reserve to construct part of the San Tin Technopole, a new hub for clustered innovation and technology development. Against this background, the workshop brought together 31 leaders and representatives across different sectors and institutions, including universities, government bodies and non-governmental organisations, to explore actionable strategies for nature conservation for sustainable development.  The activity was 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), the Research Institute for Sustainable Urban Development (RISUD), and the Department of Civil and Environmental Engineering (CEE), together with CIURG. It included technical sessions and guided tour around the Reserve.  The technical sessions, chaired by Prof. DING Xiaoli, Director of RILS, and Prof. WANG Yuhong, Director of RNUS, covered multiple topics related to the workshop theme.  These included: the Northern Metropolis development plan; digital tourism; the plan, development, and protection of Hengshui Lake National Nature Reserve; sustainable blue economy; wildlife and plants conservation; and nature-based solutions in urban design. Other guest speakers included: Ms LEUNG Kar Yee, Carrie, Chief Engineer of North Development Office at the Civil Engineering and Development Department, HKSAR; Mr SU Wansheng, Chief Executive Officer of Fujian Ticket Payment Information Technology Co., Ltd.; Mr LIU Guangning, Director of Hengshui Lake National Nature Reserve; Ms Martin KATE, Consultant at Financing Marine Conservation; Ms. Camilla ZANZANAINI, Founder and Chief Executive Officer of Nature Makers Lab; Mr David STANTON, Executive Director of Ecology and Biodiversity-Hong Kong, Aurecon; Prof. CHEN Hongyue, Professor of South China Agricultural University; Prof. LUO Chunling, Professor of Guangzhou Institute of Geochemistry, Chinese Academy of Sciences; Prof. DENG Xiaomei, Associate Professor at Tsinghua University; Dr. NAZEER Majid, Research Assistant Professor at PolyU; Prof. HUANG Shuping, Associate Professor at Fujian University of Technology.  Participants had fruitful discussions and were guided through various natural habitats during the tour, enjoying an immersive experience in nature and rethinking the human-nature relationship. This workshop is funded by the Public Policy Research Funding Scheme of the Chief Executive’s Policy Unit, HKSAR.  RILS would like to thank all parties including participants, the World Wildlife Fund Hong Kong (WWF HK) and sponsor, for supporting this meaningful event.

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.
