World Soil Day


Did you know that every year on 5 December, people around the world celebrate the soil beneath our feet and learn why it’s so important for life on Earth? World Soil Day reminds us that soil isn’t just dirt, it helps grow our food, keeps our water clean, and supports plants and animals. This day encourages us to take care of the ground we walk on and work together to protect the soil so future generations can live, grow, and thrive.

Here are some things to know:

2025 Theme: “Healthy Soils for Healthy Cities.” This year’s theme shows that soil matters not just on farms, but also in our cities. Healthy, living soil under parks, street trees, and gardens can help clean water, support plants and wildlife, reduce flooding, and make our cities greener and happier places.
Healthy soils are essential for life: Healthy soil helps grow almost everything we eat, in fact, over 95% of our food comes from soil, and it provides most of the natural nutrients plants need to grow strong.
Soil is in danger: Climate change, pollution, and erosion are damaging soils around the world. When soil becomes unhealthy, it holds less water, loses important nutrients, and makes it harder for plants, animals, and people to thrive.

          • If these books have left you feeling inspired, here are some things you can do to care for our soil and planet:

          • Become a Tiny Soil Detective! Explore fun missions from the FAO, like the “heat spy mission” and learn how soil helps cities stay healthy. Kids can try hands-on experiments and even earn a certificate for their discoveries!
          • Learn about the importance of soil. Take time to explore how soil helps grow our food, clean our water, and support nature. Understanding why soil matters can help us appreciate the world beneath our feet.
          • Protect green spaces. Help look after parks, school gardens, and community plants. Avoid stepping on planted areas, reduce waste, and support efforts to keep soil healthy so it can hold water, grow plants, and support wildlife.
          • Take action in your community. Join a local clean-up, plant a tree, start a small garden, or learn how to compost. Even simple activities can help keep soil healthy and make your neighborhood greener and more resilient.
