Every year on December 5, the world observes World Soil Day to raise awareness about the importance of healthy soil and the need to protect this precious natural resource. Proclaimed by the Food and Agriculture Organization (FAO) of the United Nations, this day highlights how soil sustains life, supports agriculture, preserves biodiversity, and plays a crucial role in combating climate change.
World Soil Day 2025 encourages individuals, farmers, governments, and organizations to work together to preserve and restore soil health for a sustainable future.
Why Soil Matters
Soil may look simple, but it is one of the most complex and vital ecosystems on Earth. Healthy soil provides:
-
Food security by supporting crops and agriculture
-
Water filtration and purification
-
Habitat for billions of organisms
-
Climate regulation through carbon storage
-
Plant growth and biodiversity
-
Foundation for human settlements
Without healthy soil, life as we know it cannot exist.
History of World Soil Day
World Soil Day was officially recognized in 2014 after the FAO adopted a resolution supported by the Kingdom of Thailand and the International Union of Soil Sciences (IUSS).
The date, December 5, also honors the birthday of the late King Bhumibol Adulyadej of Thailand, who was a strong advocate for soil conservation and sustainable agriculture.
Theme for World Soil Day 2025
The expected theme for 2025 is:
“Healthy Soil, Healthy Food, Healthy Future.”
This theme highlights the connection between soil health, nutritional food, and human well-being. It also reinforces the need for sustainable agricultural practices to protect our resources.
Major Threats to Soil Health
Today, soil across the world faces severe degradation due to:
-
Overuse of chemical fertilizers & pesticides
-
Deforestation
-
Urbanization and construction
-
