Soil is a finite natural resource. On a human time-scale it is non-renewable. However, despite the essential role that soil plays for human livelihoods, worldwide there is increasing degradation of soil resources.  Recognizing the importance of soils, the International Union of Soil Sciences (IUSS), in 2002, made a resolution proposing the 5th of December as World Soil Day. This day is aimed to celebrate the importance of soil as a critical component of the natural system and as a vital contributor to the human well-being.
