SDG 15| Life on Land

Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss

CUHK is working towards creating a campus where terrestrial ecosystems thrive and biodiversity is valued and protected. Our campus is home not only to our students and staff but also to numerous trees, flowers, and other living creatures, including several rare and precious species. The University seeks to make a positive impact on the environment through research, knowledge transfer and education, so as to ensure the next generation inherits a livable habitat.

Curriculum

12 related courses were offered in the 2022-23 academic year.

Policies

Under the University’s Sustainable Procurement Policy and Sustainable Procurement Guidelines, the purchase of black moss is strictly prohibited, and its consumption is prohibited in any meals served at campus restaurants or at any activities organized or paid for by the University.

Research

Myriapods, such as centipedes and millipedes, play important ecological roles by recycling nutrients in soil and forest ecosystems. Biologists at CUHK have sequenced the whole genome of nine centipede and millipede species, creating a useful new myriapod gene repertoire analysis tool. These high-quality reference genomes revealed several gene alternations that led to divergent behaviours, including predatory and detritivorous, in these two myriapod cousins and provided essential insights into the genomic evolution of myriapods. The research findings have been published in the journal Nature Communications.

The research team also intends to explore the hidden biology and genomics of a neglected yet striving group of organisms, to elucidate their ecological roles in soil and forest ecosystems. By gaining a better understanding of these life forms on land, we can obtain insights into their response to climate change and their contribution to nutrient recycling.

A herbarium at your fingertips

The Shiu-Ying Hu Herbarium of the School of Life Sciences has established an innovative 3D database of plant specimens. Through the combined efforts of plant taxonomy and photogrammetry, the Virtual Carpological Herbarium of Fruits and Seeds showcases more than 300 specimens, including 200 native ones in 3D models, providing an insightful reference for native plant identification, ecological surveys, and conservation of rare and endangered species.

The models can be rotated 360° and magnified at high resolutions, allowing users to inspect features smaller than 1 mm, such as close-up textures of leaves and seeds. The database is available online, and no additional software is required. The research methodology and results have been published in the scientific journal PLOS ONE.

Educational programme on ecosystems

CUHK is home to numerous plant and animal species, and its campus offers a good demonstration of how artificial habitats can serve as wildlife habitats in urban areas. This valuable lesson is promoted by ‘Experiencing Urban Biodiversity @Lake Ad Excellentiam’, a community project co-organized by the Social Responsibility and Sustainable Development Office and the Jockey Club Museum of Climate Change, and subvented by the Agriculture, Fisheries and Conservation Department. The project promotes nature exploration and appreciation of local urban biodiversity. Through the virtual learning portal and a series of workshops and outdoor activities around Lake Ad Excellentiam at CUHK, participants can explore and connect with nature while learning about the importance of biodiversity conservation.
