In July 2000 the Taleban authorities banned the cultivation of opium poppy throughout all areas under their control. In November/December 2000, reports from Afghanistan suggested vigorous implementation of the ban by the authorities. Early in February this year, UNDCP carried out a Preassessment Survey to obtain an early quantitative assessment of the area of poppy cultivation, and to determine the degree of compliance with the ban. Subsequently, in May 2001, a delegation of UNDCP major donors undertook a mission to the main poppy cultivating areas of Afghanistan to, inter alia, assess the effectiveness of the ban first hand. Both the Pre-assessment Survey and the UNDCP Donor Mission observed the near total success of the ban in eliminating poppy cultivation in Taleban controlled areas. This finding has been confirmed by the Annual Opium Poppy Survey.
