December 5th, 2020 is World Soil Day – the United Nations Observance that celebrates healthy soils for a food-secure future. This years’ campaign “Keep soil alive, Protect soil biodiversity” focuses our attention on the workers that live in the soil – from tiny bacteria to agile millipedes and earthworms – all of which contribute to processes that are indispensable to life on Earth.
These days biodiversity loss is a worry – and soil is also affected. Soil is home to more than 25% of our planet’s biodiversity. There are more living creatures in a single teaspoon of healthy soil than there are people on Earth. Soil organisms are responsible for many critical ecosystem services, on which humans depend: from supporting plant growth, to storing carbon and being a vast reservoir for pharmaceuticals. But soil biodiversity is under pressure! Unsustainable soil management affects life below ground (from www.fao.org/world-soil-day).

Check out the video below from the Food and Agriculture Organization of the United Nations. It gives a brief introduction on the main drivers, the key functions and challenges of soil biodiversity loss, indicating possible ways to enhance soil biodiversity as a nature-based solution.
