This day was established by the United Nations to highlight the value of soil as a non-renewable resource and a guarantor of biodiversity, ecosystem health, climate balance, and food security.
The theme chosen for the 2025 edition—"Healthy Soils for Healthy Cities"—focuses on the need to preserve soil functionality by promoting sustainable management practices that protect fertility, biodiversity, and ecosystem resilience. The goal is to raise awareness among institutions, businesses, and citizens of the importance of protecting this essential resource.
