World Day to Combat Desertification and Drought, celebrated around the world annually on June 17, was established by the UN General Assembly in 1994 (resolution 49/115). The date for the holiday was chosen in connection with the anniversary of the adoption of the United Nations Convention to Combat Desertification on June 17, 1994.
The Convention required states to devote the activities of this Day to raising awareness of the need for international cooperation in combating desertification and the effects of drought, as well as the progress in implementing the provisions of the Convention to Combat Desertification.
Also, the UN General Assembly proclaimed the period from January 2010 to December 2020 as the UN Decade dedicated to deserts and the fight against desertification. Its purpose is to promote activities for the protection of drylands (resolution 62/195 of 2007).
