A special FAO meeting of Member Nations directly affected by the desert locust in the Eastern Region of its distribution area in South-West Asia, held in Teheran, in October 1962, recommended that a regional commission for the control of the desert locust should be established for the region. This recommendation was confirmed by a second meeting of the Member Nations directly concerned (May 1963) and by the FAO Desert Locust Control Committee at its Eighth Session in May 1963.

A draft Agreement was considered by the FAO Council at its Fortieth and Forty-first Sessions and approved by the Conference at its Twelfth Session (December 1963) for submission to Member Nations for its acceptance.

In accordance with paragraph 1, Article XX, the Agreement entered into force on 15 December 1964, the date of receipt of the third instrument of acceptance. The Agreement was registered with the Secretariat of the United Nations on 2 April 1965 under No. 7663.

At its Twelfth Session (March 1977), the Commission adopted amendments to the Agreement which were approved by the FAO Council at its Seventy-second Session (November 1977). These amendments entered into force for all the parties to the Agreement.

At its Twenty-second Session (September 2000), the Commission adopted further amendments to the Agreement. The amendments were approved by the FAO Council at its Hundred and Twenty-first Session (October-November 2001) and entered into force immediately.
