World Soil Day (WSD) is held annually on 5 December as a means to focus attention on the importance of healthy soil and advocating for the sustainable management of soil resources.

An international day to celebrate soil was recommended by the International Union of Soil Sciences (IUSS) in 2002. Under the leadership of the Kingdom of Thailand and within the framework of the Global Soil Partnership, FAO has supported the formal establishment of WSD as a global awareness- raising platform.

The FAO conference unanimously endorsed World Soil Day in June 2013 and requested its official adoption at the 68th UN General Assembly. In December 2013 the UN General Assembly responded by designating 5 December 2014 as the first official World Soil Day.

This date, 5 December for WSD was chosen because it corresponds with the official birthday of HM King Bhumibol Adulyadej, the king of Thailand, who officially sanctioned the event.

In 2016 this day was officially recognised in memory of and with respect for this beloved monarch who passed away in October 2016 after seven decades as head of state.

#StopSoilPollution is at the heart of the Global Soil Partnership’s mandate as demonstrated by the Global Symposium on Soil Pollution. We work to ensure that people have safe and nutritious food to ensure an active and healthy life without endangering essential ecosystems services. It is time to #StopSoilPollution, join forces, and turn determination into action. – FAO
