World Rivers Day was established in 2005 during the United Nations Water for Life Decade. It is celebrated annually on the fourth Sunday of September. Initiated by renowned Canadian river advocate Mark Angelo, the day is celebrated in over 70 countries.
😆 A fun suggestion: While World Rivers Day isn’t officially a celebration of Rivers Cuomo, the lead singer and guitarist of the American rock band Weezer, or others named Rivers, there’s no reason you can’t give them a nod on this day too if you know someone by that name!
The purpose of this day is to highlight the importance of rivers. It also strives to increase public awareness and encourage the improved stewardship of all rivers around the world. Events on this day focus on educating the public about the critical role rivers play in supporting biodiversity and human livelihoods. Each year often has a specific theme, focusing on different aspects of river conservation.
What do people do on World Rivers Day? Well, activities vary a lot but they include river clean-ups, habitat restoration, nature walks, paddle events, school projects, art displays, and even music festivals.
