The soil is a finite natural resource. On a human time scale, it is non-renewable. However, despite the essential role that soil plays in human subsistence, there is a global increase in the degradation of soil resources due to inappropriate management practices, population pressure driving unsustainable intensification, and inadequate governance over this essential resource.and inadequate governance over this essential resource.

Among the most important eco-systemic functions that the soil performs are the following regulating the amount of water and floods, regulate climate, surface water quality and the health of aquatic systems, as well as being the largest terrestrial reservoir of CO2 of the atmosphere and host great biodiversity.

The soils have great potential for filtering and buffering contaminants, degrading and mitigating the negative effects of pollutants, but this capacity is finite. Most pollutants come from human activities, such as unsustainable agricultural practices, industrial activities and mining, untreated urban waste, and other environmentally unfriendly practices.

In the 2030 Agenda for Sustainable Development, the Sustainable Development Goals 2, 3, 12 and 15 have targets that recommend direct consideration of soil resources, especially soil contamination and degradation in relation to food security.

La FAO has launched a worldwide call for countries to participate in this contest with the theme: "Being the solution to soil contamination".

"To be the solution to soil contamination."The soil health and therefore access to safe, healthy and nutritious food, means working together with the public, private, academic and scientific sectors to ensure soil health and therefore access to safe, healthy and nutritious food, and, to achieve this, a lifestyle and sustainable soil management must be adopted, which requires conscious and continuous work. It is time to discover this threatening reality. Combating soil contamination requires us to join forces and turn determination into action.

The general objective of this celebration is: To promote the importance of soils for food, nutrition, water quality, life and health of the planet.

And we specifically seek to invite public and private companies, producers, national and international research institutes, artists and academia in general, to participate in this celebration through their work, art, research and exchange of experiences.

Building the "Soil Guardian Network". and work among public and private actors and institutions involved in the management, sustainable production and conservation of this resource.
