World Wetlands Day—“Wetlands and Traditional Knowledge: Celebrating Cultural Heritage”, 2 February 2026
World Wetlands Day, observed annually on 2 February, highlights the vital role wetlands play in supporting biodiversity, regulating water systems, and sustaining human well-being. As some of the world’s most productive ecosystems, wetlands provide essential services such as flood control, water purification, carbon storage, and habitat for diverse species, yet they remain under increasing threat.
The 2026 theme, “Wetlands and Traditional Knowledge: Celebrating Cultural Heritage,” spotlights the deep-rooted connections between wetland ecosystems and the cultural practices, wisdom, and stewardship of communities around the world. By drawing on traditional knowledge alongside scientific insight, this theme emphasizes how cultural heritage contributes to sustaining and restoring these dynamic landscapes.
MDPI supports this global observance by showcasing research that advances wetland science, conservation, and sustainable management, helping to safeguard these critical ecosystems for future generations.
