World Day to Combat Desertification
This is a past event
In 1994, the United Nations General Assembly declared June 17 the World Day to Combat Desertification and Drought to promote public awareness of the issue, and the implementation of the United Nations Convention to Combat Desertification (UNCCD) in those countries experiencing serious drought and/or desertification, particularly in Africa.
