World Soil Day

World Soil day celebrates the importance of soil as a critical component of the natural system and as a vital contributor to the human commonwealth through its contribution to food, water and energy security and as a mitigator of biodiversity loss and climate change.

It is celebrated particularly by the global community of 60 000 soil scientists charged with responsibility of generating and communicating soil knowledge for the common good. many events focussed on increasing the public awareness of soil and its contribution to humanity and the environment.

It is held on December 5th because it corresponds with the official birthday of H.M. King Bhumibol Adulyadej ,The King of Thailand, who has officially sanctioned the event.

The FAO Conference in June 2013 unanimously endorsed World Soil Day on 5th December and requested the 68th UNGA to have it officially adopted.
