World Soil Day (WSD) is held annually on December 5 to focus attention on the importance of healthy soil and advocate for the sustainable management of soil resources.
In 2002 the International Union of Soil Sciences (IUSS) recommended that an international day to celebrate soil should be established. Under the leadership of the Kingdom of Thailand and within the framework of the Global Soil Partnership, the Food and Agriculture Organization (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. The UN responded by designating December 5, 2014, as the first official World Soil Day.
