Soil Ecosystem Services
Ecosystem services are the benefits people obtain from the ecosystem (MEA 2005).
As an integral part of the terrestrial ecosystem, soils play a crucial role in the provision of a myriad of so-called soil ecosystem services:

A conceptual diagram was developed by Adhikari and Hartemink (2016), which relates individual soil properties to soil ecosystem services.

Soil ecosystem services are vital components to all aspects of life and they support the production of ecosystem goods and services, such as:
- Food, fibre, and energy provision
- Water storage and purification
- Neutralization, filtering and buffering of pollutants
- Natural hazard regulation
- Climate regulation
- Archive natural and cultural phenomena…
Soils variety also allows a diversity of soil ecosystem services, which benefit not only humans but also soil biota and the surrounding environment.
In a mountainous environment, some services are in comparison to lowland areas of particular importance such erosion control or flood protection.
The provision of soil ecosystem services relies on soil properties, processes and functions. Furthermore, healthy and diverse soils ensure biodiversity among soil biota (soil biodiversity), which in turn guarantees the provision of soil ecosystem services.
