World Soil Day 2025

The World Soil Day is celebrated the 5th december, established by the 68th Session of the United Nations General Assembly to draw attention to the crucial importance of this vital resource. The theme chosen for the 2025 edition is "Healthy Soils for Healthy Cities," which emphasizes the essential link between soil quality and the well-being of urban populations.

Beneath asphalt, buildings, and roads lies soil that, when permeable and vegetated, helps absorb rainwater, regulate temperature, store carbon, and improve air quality. But when sealed with concrete, it loses these functions, making cities more vulnerable to flooding, global warming, and pollution.

Therefore, this day invites everyone, from politicians to citizens, to rethink urban spaces from the ground up, to build greener, more resilient, and healthier cities.

  • The 95% of our food comes from soil.
  • 33% of soils are degraded.
  • Producing even just 2–3 cm of soil can take up to 1,000 years.
  • Soil provides 15 of the 18 natural chemical elements essential for plants.
  • There are more living organisms in one tablespoon of soil than there are people on Earth.
  • 2 billion people worldwide suffer from micronutrient deficiency, known as hidden hunger.
  • Through sustainable soil management, up to 58% more food could be produced.
  • Soil hosts nearly 59% of Earth’s species.

According to the latest SNPA report “Soil Consumption, Territorial Dynamics and Ecosystem Services” in 2024 nearly 84 square kilometers were covered by new artificial surfaces, a 16% increase compared to the previous year. With more than 78 km² of net soil consumption, this is the highest value of the last decade. In contrast, just over 5 km² were returned to nature, leaving the situation unbalanced: every hour, an area of soil of about 10,000 square meters is lost, as if one tile after another were being removed from the mosaic of the landscape.
