World Rivers Day 2026: Conserving Freshwater Ecosystems – 27 September 2026

What happened

World Rivers Day is observed on the fourth Sunday of September. In 2026 it falls on 27 September. The day focuses on the value of rivers and encourages improved stewardship of freshwater resources. In India, river rejuvenation links to Namami Gange, National River Conservation Plan and state river-front projects.

Background

Rivers support drinking water, irrigation, inland navigation, biodiversity and culture. Pollution, encroachment and climate-driven flow changes remain major challenges. Global observance grew from the Water for Life Decade initiatives and civic river clean-up movements.
