Service Learning Program in Sri Lanka: Empowering Global Communities through Technology

A delegation of 55 staff and students from the Department of Land Surveying and Geo-Informatics (LSGI), The Hong Kong Polytechnic University (PolyU), recently completed a Service Learning programme in Sri Lanka, combining technological innovation, community engagement and cross-cultural exchange. During the programme, the team visited the Joint Research and Demonstration Center for Water Technology (JRDC) and participated in academic exchanges with the University of Peradeniya. Students gained first-hand exposure to local sustainability initiatives and water technology applications, while exploring how geospatial technologies can contribute to community development. The delegation was welcomed by the Vice Chancellor of the University of Peradeniya. Ir. Prof. Wallace Lai, Associate Head of LSGI, highlighted the importance of Service Learning in connecting academic knowledge with real-world challenges and fostering global citizenship among students. As part of the programme, Dr. Yawei Wang from the Chinese Academy of Sciences delivered a guest lecture on scientific innovation and international collaboration. The session provided valuable insights into emerging technologies and inspired students to consider the broader societal impact of scientific research. A key component of the programme was educational outreach in primary and secondary schools in Galle. LSGI students designed and delivered a series of interactive workshops featuring Virtual Reality (VR), Augmented Reality (AR), Unmanned Aerial Vehicles (UAVs), and LiDAR technologies. These hands-on activities introduced local students to cutting-edge geospatial technologies and stimulated their interest in science and innovation. The team also organized Chinese cultural activities, including lacquer fan painting, tie-dye art, music, and sports sessions. These activities encouraged meaningful interaction between students from different cultural backgrounds and promoted mutual understanding and friendship. The programme received highly positive feedback from local schools and community partners. For participating students, the experience provided a unique opportunity to apply their professional knowledge in a real-world setting while developing leadership, communication and intercultural competencies. This Service Learning initiative reflects PolyU and LSGI’s commitment to nurturing socially responsible graduates and advancing international engagement through education, technology and community service. As Sri Lanka is an important partner country under the Belt and Road Initiative, the programme provided a valuable platform for strengthening educational cooperation, cultural exchange and capacity building, while fostering long-term partnerships that contribute to sustainable and inclusive development.

PolyU x BOCHK “Building the Future: Robotics for the International Lunar Research Station” Lunar Robot Design Competition concludes successfully

PolyU has co-organised the space-themed programme PolyU x BOCHK “Building the Future: Robotics for the International Lunar Research Station” with the Education Bureau. The initiative aims to inspire secondary school students’ interest in space science and engineering, enabling them to put STEM knowledge in practice and nurturing future technology talent. One of the programme’s highlights was the Lunar Robot Design Competition, where secondary students were required to design scientifically grounded robotic solutions for exploration of the lunar south pole. The competition has received a total of 65 design proposals from students of 52 schools in the GBA. An award ceremony was held on 29 May 2026 at PolyU. The Lunar Robot Design Competition focused on four themes: Exploration and Surveying Robots, Construction and Infrastructure Robots, Astronaut Support and Logistics Robots, and Multi-Robot Cooperative Systems. After evaluation by a panel of PolyU aerospace experts and members of the Hong Kong Society of Astronautics, teams from Pui Kiu College, Good Hope School and Malvern College Hong Kong were named champion, first runner-up and second runner-up respectively. Prof. Bo WU, Associate Head (Research) of the Department of Land Surveying and Geo-Informatics, Associate Director of the Research Centre for Deep Space Explorations, and Professor of the Department of Land Surveying and Geo-Informatics, expressed his appreciation for the winning proposals, describing the students’ creative concepts as inspiring for the future scientific development of lunar exploration missions.

PolyU research reveals snow droughts continue to threaten global food security and calls for climate-resilient agriculture practices to promote sustainable development

A research team, led by Prof. Shuo WANG, Associate Professor of LSGI, a core member of the Research Institute for Land and Space, and a member of the State Key Laboratory of Climate Resilience for Coastal Cities, from the Department of Land Surveying and Geo-Informatics (LSGI) at The Hong Kong Polytechnic University (PolyU), has used innovative explainable machine learning to uncover the persistent negative impact of snow droughts on winter wheat yields. As warmer winters become more prevalent, insufficient snowfall leaves wheat vulnerable to frost damage and water stress, posing a major threat to global food security. The findings have been published in Nature Food. Over the past 60 years, the frequency of snow droughts across the Northern Hemisphere’s winter wheat croplands has risen sharply. The proportion of affected croplands surged from 46–54% in 1960–1970 to 70–99% in 2010–2020, indicating that snow droughts have evolved from a localised risk into a widespread phenomenon. The research team developed the XGB-SHAP model framework, which combines Extreme Gradient Boosting (XGBoost) with Shapley Additive exPlanations (SHAP) to quantify the direct impact of snow drought on yields while excluding interference from other climate factors. The study found that approximately 45% of croplands in the Northern Hemisphere experienced significant adverse effects, with Europe, Central Asia and the United States being the most severely affected. In East Asia, the yield benefits of longer growing seasons are diminishing, and the hydrothermal balance is becoming increasingly unstable. Prof. Shuo WANG noted, “As global warming continues, climate risks are no longer limited to ‘acute stressors’ such as heatwaves, but also include gradually accumulating and far-reaching ‘chronic stressors’ such as snow droughts. As winter wheat is a major commodity in global agricultural trade, the effect of its yield variability can ripple through global trade networks, driving up food prices and potentially leading to regional food security crises.” The research team recommends strengthening climate resilience by enhancing crop varieties, improving agricultural management, and incorporating snow cover monitoring into early warning systems. These steps will help maintain stable food production and steer global agriculture towards a more sustainable future.   Press release: English - https://polyu.me/4nOZhRH; Chinese - https://polyu.me/4u1BBv3   Online coverage: The National Tribune - https://polyu.me/4dNTZ4t Mirage - https://polyu.me/42YLSx2 Ta Kung Pao - https://polyu.me/4e8weVZ Wen Wei Po - https://polyu.me/3RKk4dd  

LSGI Scholar contributing to Nation’s Deep‑Space Exploration

Prof. Bo WU, Fiona Cheung Professor in Spatial Science, Associate Head (Research) of LSGI, and Associate Director of PolyU’s Research Centre of Deep Space Explorations (RCDSE), was interviewed to share his insights on Hong Kong’s role in the nation’s aerospace development.  He noted that as the nation’s 15th Five-Year Plan calls for accelerating the building of a strong aerospace sector and explicitly supports Hong Kong’s development into an international I&T hub, Hong Kong researchers are eager to contribute their expertise. “PolyU teams have long actively participated in the country’s deep‑space exploration missions,” he said. “Seeing our research adopted at the national level has brought a strong sense of achievement and become a powerful motivation for us to continue contributing to the nation’s space programme.”  During the preparation for China’s Mars probe Tianwen‑1 landing, Prof. WU’s team was tasked with analysing a landing area roughly 11 times the size of Hong Kong’s territory. Using conventional imaging methods, the work would have taken more than six months. By applying artificial intelligence, the team reduced the processing time to less than three months, enabling the Zhurong rover to touch down safely on 15 May 2021.   Online coverage: Ta Kung Pao - https://polyu.me/4oawzv3 Bauhinia - https://polyu.me/4wHXd1Y Tech Now - https://polyu.me/3PK58uY Hong Kong-Invest - https://polyu.me/3Rs3qiB 香港網絡 - https://polyu.me/4wOggI0 華人號 - https://polyu.me/4u2K4xP
