Remote Sensing: A Tool for Earth and Space Exploration
Remote sensing is the discipline of acquiring and interpreting aerial images of the earth or other planets using sensor-based technology. Those images, covering subjects like the earth’s surface, the atmosphere, oceans, objects and phenomenon, are then analysed to provide precise data that would not be possible to obtain easily by other means. Dr Joseph Michalski, Associate Professor, Department of Earth Sciences at the University of Hong Kong, is a geologist and planetary scientist who uses remote sensing to study the mineralogy and geology of planets at HKU’s Planetary Mineralogy and Spectroscopy Laboratory.
The Business of ‘Best Before’
A student-led social enterprise is addressing the problem of food waste by selling products that have passed the ‘best before’ date but are still safe to eat.
A Global Voice of Sustainability Policy
HKU’s Policy for Sustainability Lab has been recognised by the United Nations as a new member of the International Partnership for the Satoyama Initiative (IPSI), a programme begun in 2010 with the aim of ‘promoting collaboration in the conservation and restoration of sustainable human-influenced natural environments through broader global recognition of their value’.
Making Marine Eco-systems and Seafood Safer

Data: Now Open for Business
There is enormous public benefit from these plans for making government data open. The reality is the government can never supply enough information, and the cost of making these data available is marginal.
