World Water Day 2026: Protecting Every Drop

On this World Water Day (March 22), let us pause to remember that water is not just a resource — it is life itself. Every drop we use carries responsibility. As climate change intensifies, freshwater sources decline, and pollution threatens aquatic ecosystems, the need to conserve water has never been more urgent. Turning off a running tap, reducing daily waste, and embracing sustainable habits may seem small, but together they create powerful change. At the same time, meaningful progress depends on science and innovation.

At the School of Energy and Environment, City University of Hong Kong, our distinguished faculty — Prof. Wen-Xiong WANG, Prof. Zhiguo Yuan, Prof. Moriaki YASUHARA, Prof. Henry Y. HE, Prof. Xi CHEN, and Prof. Xuneng TONG — are leading impactful research in water quality, environmental protection, wastewater treatment, and sustainable water management. Through their dedication and expertise, they are helping safeguard our most precious resource and shape a more resilient, water-secure future.

This World Water Day, let us act with urgency, innovate with purpose, and protect every drop for generations to come.
