World Soil Day 2025

World Soil Day is annually held on December 5 to highlight soil's importance on Earth. We need soil for basic survival - food and energy. It is linked with the United Nations' (UN) Year of Soil.

Deforestation and Bad Farming

Soil is made up of organic remains, clay and rock particles, found on the Earth’s surface. It contributes to food, reduces biodiversity loss, and secures energy. Problems like deforestation, bad agricultural practices and pollution causes soil degradation and erosion.

The UN saw a need to raise awareness about the dangers of soil loss, so it made World Soil Day and official day. It was first celebrated on December 5, 2012, which corresponded with the birthday of Thai king Bhumibol Adulyadej, who officially sanctioned the event.

What to Do?

Thousands of soil scientists and organizations, like the International Union of Soil Sciences, promote the day via social media, YouTube videos, and local events to talk about issues such as soil erosion and preserving soil.
