Observed annually on February 2, World Wetlands Day marks the adoption of the Ramsar Convention in 1971 and provides an international framework for recognizing the role of wetlands in environmental protection and sustainable development. The 2026 edition is held under the theme “Wetlands and traditional knowledge: Celebrating cultural heritage,” drawing attention to the long-standing relationships between wetland ecosystems and the cultural practices, knowledge systems, and governance structures developed by communities over centuries. The theme highlights how inherited ecological knowledge, often embedded in rituals, seasonal calendars, land-use practices, and spatial organization, has shaped resilient interactions between human settlements and water-based landscapes. …World Wetlands Day 2026 emphasizes the need to reconsider prevailing development models by integrating traditional knowledge with scientific research and planning strategies in efforts toward conservation, restoration, and long-term environmental stewardship.
