World Rivers Day takes place on September 26, 2021. World Rivers Day is a global celebration of the world's waterways, observed every last Sunday in September. Established in 2005, it highlights the many values of rivers and strives to increase public awareness while encouraging the improved stewardship of rivers around the world. Rivers in every country face an array of threats, and World Rivers Day promotes the active involvement of citizens to ensure the health of rivers in the years ahead.
Events include riverside cleanups, habitat restoration, nature walks, paddle trips, school projects, art displays, music festivals, and parades. Citizens are encouraged to join an event in their area, or start one of their own. World Rivers Day has been endorsed by various agencies of the United Nations and is intended to complement the broader efforts of the United Nations Water For Life Decade.
