RILS Director shares views on issue of land subsidence

Prof. DING Xiaoli, Director of the Research Institute for Land and Space (RILS) and Chair Professor of Geomatics in the Department of Land Surveying and Geo-Informatics, was interviewed by the journal Nature and BBC World Service’s programme “Newshour”, to share his views on issue of land subsidence. Prof. DING pointed out that subsidence is a problem in many parts of the world. He said that, in cities such as Macao and Hong Kong where no groundwater is used, subsidence mainly comes from consolidation — downward movement as a result of soil being compressed — after land reclamation. A paper recently published in Science suggested that some 16% of the mapped area of China’s major cities is sinking rapidly, and one in ten residents of China’s coastal cities could be living below sea level within a century. Prof. Ding said that the study provides an interesting snapshot of the situation in China, and crucially links the issue to the populations affected.

PolyU studies impacts of urban industrial land expansion on economic growth and carbon dioxide emission

A research by Prof. WENG Qihao, Associate Director of the Research Institute for Land and Space (RILS), Member of the Otto Poon Charitable Foundation Smart Cities Research Institute (SCRI) and Chair Professor of Geomatics and Artificial Intelligence, and his research team, titled “Unequal impacts of urban industrial land expansion on economic growth and carbon dioxide emissions” was recently published in the journal Communications Earth & Environment. The team used satellite data and machine learning to map industrial land at 30 m resolution in ten countries with substantial industrial value-added, and analysed the impact of industrial land expansion on economic growth and emissions in 216 subnational regions from 2000 to 2019. They found that industrial land expansion was the leading factor for economic growth and emissions in developing regions, contributing 31% and 55%, respectively. Conversely, developed regions showed a diminished impact (8% and 3%, respectively), with a shift towards other economic growth drivers like education. The findings encourage developing regions to consider the adverse effects of climate change during industrial land expansion and that developed regions prioritise human capital investment over further land expansion.

Concurrent heatwaves and sea level rises happening more at coastal locations, PolyU study finds

A research conducted by Dr WANG Shuo, Member of the Research Institute for Land and Space (RILS), the Research Institute for Sustainable Urban Development (RISUD) and the Otto Poon Charitable Foundation Smart Cities Research Institute (SCRI), Associate Professor in the Department of Land Surveying and Geo-Informatics (LSGI), and his team has found that the concurrent occurrence of heatwaves and extreme short-term sea level rises at coastal locations significantly increased between 1998 and 2017 when compared to the preceding 20 years. The study also predicted that, under a modelled high emissions scenario, the probability of the occurrence of such events in 2025–2049 may multiply by fivefold. The research findings provide scientific evidence and guidance for improving climate adaptation strategies in response to extreme weather events, which will aid in the development of climate-resilient coastal cities. The study has been published in the journal Communications Earth & Environment.

Green and cool roofs reduce energy use substantially, PolyU study finds

Prof. WENG Qihao, Associate Director of the Research Institute for Land and Space (RILS), Member of the Otto Poon Charitable Foundation Smart Cities Research Institute (SCRI) and Chair Professor of Geomatics and Artificial Intelligence, and his research team studied the energy-saving potential of green roofs and cool roofs in reducing building energy consumption. The paper was published in the journal npj Urban Sustainability. The study evaluated the green roof and cool roof strategies in six global cities, including Cairo, Hong Kong, Seoul, London, Los Angeles, and Sao Paulo, under current and future climate change scenarios. Results showed that in future climates, the implementation of these strategies at the city level can lead to up to 65.51% annual energy reduction and 71.72% reduction in Heating Ventilation and Air Conditioning (HVAC) consumption by 2100. These findings can guide the implementation of these strategies in different climatic zones worldwide, informing the selection and design of suitable roof mitigation strategies for specific urban contexts.

Geomatics expert Prof. CHEN Jun delivers a distinguished lecture on spatial-temporal information for sustainable development

Prof. CHEN Jun, Chief Scientist at the National Geomatics Center of China and Fellow of the Chinese Academy of Engineering, delivered the 16th PAIR Distinguished Lecture titled “Spatial-temporal Information for High Quality Sustainable Development” on 27 March 2024. The hybrid lecture attracted over 200 participants joining in person and online from more than 20 countries and regions across Australia, Asia, Europe and North America. It was also broadcast live on multiple social media platforms, captivating an online viewing audience of over 10,700. The lecture commenced with a welcome speech and speaker introduction by Prof. WANG Zuankai, Associate Vice President (Research and Innovation). In his presentation, Prof. Chen first gave a brief introduction to the United Nations’ 17 Sustainable Development Goals (SDGs) as well as the SDG monitoring practices in Mainland China. He pointed out that the Nation has adopted the high quality sustainable development concept, which emphasises harmonising the social, economic and environmental aspects in national development. Next, he elaborated on a pilot project that he led to measure Deqing County’s progress towards SDGs using geospatial and statistical information. The project was selected by the UN Department of Economic and Social Affairs as one of the first 16 good SDGs’ practices in 2020. After that, Prof. Chen shared that the achievement of sustainable development requires holistic and systematic research to build a digital governance system that can provide the basis for the scientific and orderly development of national territorial space. He also explained how territorial space sustainability studies can help unveil and analyse various patterns, such as the distributions of population, enterprises and public service facilities, and the relationships between them. To conclude, Prof. Chen introduced the national program on the development of the Realistic Geospatial Landscape Model (3dRGLm), which can generate digital description and representation of the real 3D geospatial spaces. This new geographic information system can support the Nation in achieving natural resources management and high quality sustainable development.
