🌱 World Soil Day 2025: Healthy Soils for Healthy Cities
Every year on December 5th, World Soil Day invites us to dig deeper - literally and figuratively- into the vital role soil plays in sustaining life. In 2025, the theme “Healthy Soils for Healthy Cities” shines a spotlight on urban soils and their overlooked power to shape resilient, sustainable communities.
Soil is more than dirt beneath our feet. It’s a living ecosystem that:
• Supports food production and urban agriculture
• Filters water and stores carbon
• Regulates temperature and sustains biodiversity
• Anchors green spaces and reduces disaster risks
Yet urbanisation threatens these benefits. Soil sealing (covering land with concrete or asphalt), pollution and unchecked expansion degrade soil health, intensify heat islands and increase flood risks.
