RILS Successfully Hosted Distinguished Lecture on New Challenges to Understand Global Changes in Cybernetic Times (只有英文版本)

The lecture titled "New Challenges to Understand Global Changes in Cybernetic Times" delivered by Prof. Riccardo VALENTINI, Professor of Forest Ecology at the Department for Innovations in Biological, Agri-food and Forest Systems, University of Tuscia, Italy, and moderated by Prof. Charles WONG Man Sing, Associate Dean (FCE), Professor of LSGI, and Management Committee Member of RILS at The Hong Kong Polytechnic University, was successfully held on 25 June 2026. The event attracted a robust audience of nearly 100 participants, with over 70 attendees joining on-site at Block Z and an additional 20 connecting virtually. This strong turnout reflected the significant interest in the intersection of biogeosciences and emerging technologies as the Earth system undergoes unprecedented transformation.   During the session, Prof. Valentini framed the current era as "cybernetic times," characterized by complex feedback loops binding planetary processes, human activities, and intelligent machines. The discussion highlighted how the convergence of the Internet of Things, artificial intelligence, and robotics is revolutionizing our capacity to observe and model the planet. Key topics included the use of distributed sensor networks for real-time environmental monitoring, AI-driven analysis for detecting early-warning signals of abrupt change, and autonomous robotic platforms that extend scientific observation into extreme environments where humans cannot reach.   The lecture addressed the profound epistemological and methodological questions raised by this technological convergence, particularly regarding how to integrate these tools into a coherent understanding of Earth system dynamics. Prof. Valentini emphasised the need for a new research agenda where technology is viewed not merely as an instrument, but as a constitutive element of a new way of knowing and caring for a rapidly changing planet. The event concluded with an engaging Q&A session, during which the audience actively exchanged ideas on how these innovations can support timely climate action in the face of nonlinear dynamics and tipping points that often outpace traditional models and institutions.  

理大研究揭示雪旱持續威脅全球糧食安全　倡建氣候韌性農業實踐　推動可持續發展

由理大土地及空間研究院、潘樂陶慈善基金智慧城市研究院及可持續城市發展研究院成員兼土地測量及地理資訊學系副教授王碩教授帶領的研究團隊，利用創新的可解釋機器學習技術，揭示雪旱對冬小麥產量帶來顯著而持續的負面影響，反映全球糧食安全正面對前所未有的挑戰。這項突破性研究為建構氣候韌性農業、保障糧食安全及推動可持續發展，提供關鍵的科學依據。此研究與香港大學及美國加州大學爾灣分校學者合作進行，研究結果已刊登於國際權威期刊《Nature Food》。   過去60年間，北半球冬小麥種植區的雪旱發生頻率顯著上升。受雪旱影響的農地比例，已由1960至1970年間的46%至54%，大幅增至2010至2020年間的70%至99%，反映雪旱已由局部風險演變為廣泛性影響。   為準確識別雪旱對作物產量的直接影響，研究團隊開發了XGB-SHAP模型框架，結合極端梯度提升（XGBoost）與夏普利加性解釋（SHAP）方法，有效排除高溫、降雨等其他氣候因素的干擾，定量分析雪旱對冬小麥產量的直接影響。研究亦系統性分析積雪、作物生長與水分條件之間的交互關係，為推動氣候韌性農業系統建設提供堅實的實證基礎。   透過XGB-SHAP模型分析，研究發現北半球約45%的農地受到雪旱顯著衝擊，其中以歐洲、中亞及美國情況最為嚴重。至於東亞地區，過往因暖冬而延長作物生長期所帶來的增產效益正逐步消退，區域水熱平衡亦愈見不穩。研究進一步指出，施肥量增加、凍害加劇及降水減少，是提高冬小麥對雪旱敏感度的三大主因。雖然提升土壤養分有助促進作物生長，但同時亦會增加作物對水分供應及積雪保溫的依賴；一旦發生雪旱，減產風險反而會被進一步放大。   展望未來，研究團隊建議從作物品種改良、農業管理及風險監測三方面提升農業系統的氣候韌性。除了應加強培育兼具抗寒及抗旱能力的作物品種，農業管理模式亦需由傳統投入密集型生產，逐步轉向更精準且可持續的養分管理系統，而積雪監測亦應納入農業風險評估與預警系統。透過及早識別雪旱風險並提升農業系統適應能力，將有助在氣候變化下維持糧食生產穩定，推動全球農業邁向更可持續的未來。   新聞稿：https://polyu.me/4u1BBv3   網上報導： The National Tribune - https://polyu.me/4dNTZ4t Mirage - https://polyu.me/42YLSx2 大公報 - https://polyu.me/4e8weVZ 文匯報 - https://polyu.me/3RKk4dd

土地及空間研究院公開講座在香港理工大學成功舉行 (只有英文版本)

On 23 March 2026, Professor Roland BÜRGMANN from the Department of Earth and Planetary Science, University of California, Berkeley, delivered a Public Lecture titled “Kinematics, Dynamics and Hazard of Slow-Moving Landslides” at The Hong Kong Polytechnic University. The lecture was moderated by Prof. SHI Guoqiang and co-organised by the Research Institute of Land and Space (RILS) and Department of Land Surveying and Geo-Informatics (LSGI). Prof. BÜRGMANN provided a comprehensive overview of slow-moving landslides as a significant natural hazard worldwide. He emphasized that despite advances in monitoring techniques, key questions remain regarding their spatial distribution, geometry, and underlying deformation dynamics. Drawing on recent observations from multiple study areas, he demonstrated how integrated approaches—combining satellite and airborne InSAR measurements, field-based GNSS and inclinometers, and seismic data—reveal a complex spectrum of landslide behavior. These observations highlight long-term stable motions modulated by multi-year and seasonal precipitation patterns, as well as short-term variations such as daily accelerations and transient slip events along bounding surfaces. The talk underscored that improving our understanding of landslide kinematics and dynamics is essential for identifying the conditions that may ultimately lead to catastrophic failure. The lecture concluded with an engaging Q&A session, where participants discussed topics including rainfall-triggered instability, multi-scale monitoring techniques, and the implications of geophysical observations for hazard assessment. The interactive exchange fostered deeper insights into landslide processes and their broader environmental and societal impacts.   About Prof. Roland BÜRGMANN: Prof. Roland BÜRGMANN received his M.S. at the University of Colorado, Boulder in 1989 and his Ph.D. at Stanford University, in 1993. He is currently Professor at the Department of Earth and Planetary Science at UC Berkeley. His research interests are in active tectonics, crustal deformation and lithosphere rheology. He coauthored more than 350 papers in peer-reviewed journals. He received the 2026 Howard D. Day Prize and Lectureship of the National Academy of Sciences and was the 2024 Bowie Lecturer and 2013 Birch Lecturer of the American Geophysical Union (AGU). He is a Fellow of the American Association for the Advancement of Science (AAAS), a Fellow of the AGU, and received the 2005 Bessel Prize of the Humboldt Foundation in Germany. Among other service, BÜRGMANN recently served as chair of the USGS National Earthquake Prediction Evaluation Council (NEPEC), as member of the USGS Scientific Earthquake Studies Advisory Committee (SESAC), and is currently a member of the DFG Expertengremium für die Exzellenzstrategie in Germany, the NASA OPERA CSLC Working Group, and the Integration and Innovation Advisory Committee of the EarthScope Consortium.

地面下的創新：賴緯樂教授於香港電台電視節目談智慧地下管線技術

土地及空間研究院成員、土地測量及地理資訊學系副系主任（教學）及教授賴緯樂教授，近日接受香港電台電視節目《非凡香港》訪問，探討本港在維護密集地下基礎設施方面的獨特挑戰。 賴教授解釋，鑑於香港地勢多山且水壓偏高，政府冀在 2030 年前透過工程創新將水管滲漏率降至 10% 以下。為此，政府已成立「地下水管測漏中心」以及「管道機械人聯合實驗室」，推動相關培訓及研發。傳統檢測主要依賴聲學傳感器，但近年技術已引入透地雷達和人工智慧演算法，能從城市噪音中辨識滲漏特徵。其中一項關鍵創新是「智能水管內窺鏡」，這是一種專為檢查受壓水管內部結構而設計的內視鏡機器人。 賴教授指出，香港若能妥善解決在管線維護上的複雜問題，將可為大灣區及其他地區提供可借鑑方案。此外，這些地理空間技術也延伸至考古研究，協助定位隱匿的隱藏的歷史遺跡，促進城市可持續發展與文化保育之間的平衡。   網上報導： 香港電台 - https://polyu.me/4cuhCzT（00:34 - 17:41）（只有英文）

香港電台訪談：土地及空間研究院院長暢談水上社區及漂浮建築新趨勢

土地及空間研究院院長丁曉利教授、測繪及地理資訊講座教授，早前接受香港電台《十萬八千里》節目專訪，深入剖析水上社區及漂浮建築的最新發展趨勢和潛力。 位於荷蘭阿姆斯特丹的Schoonschip水上漂浮住宅區，是目前全球最具代表性的浮動建築項目之一。該社區座落於當地運河之上，由三十幢現代化水上住宅組成，其中一半為複式單位。這些住宅的結構與陸地建築相似，採用水泥船作壓艙，並以固定臂與岸邊連接，確保整體結構穩定。約三分之一的住宅屋頂設有綠化及太陽能板，居民可將剩餘電力在社區內分配出售或售予國家電網，充分實踐可持續生活模式。Schoonschip的浮動建築能隨水位升降，有效防洪。2022年風暴期間，居民僅需加固戶外物品，建築仍保持安全穩定。 丁教授指出，現今的浮動建築一般不高於三層，結構下方設有浮台支撐，並以高耐久混凝土建造，同時採用柔性管道連接供水、排污等基礎設施。這類建築不僅有助紓緩土地短缺及房屋供應緊張的問題，亦能有效應對氣候變化帶來的水患風險。除荷蘭外，馬爾代夫等低窪國家亦積極發展水上社區，並將人工珊瑚礁及深海冷卻技術等創新綠色技術融入設計之中，以推動生態保育與可持續創新。 丁教授續指，雖然水上建築須面對颱風、地震等極端天氣與災害挑戰，但其在防災能力、環保效益及靈活用地方面的優勢，正推動全球更多城市探索水上生活的可能性。   網上報導： 香港電台 - https://polyu.me/4apMf8b（23:17 - 34:16）
