At its Annual General Meeting in 2001 (AGM01), the Consultative Group on International Agricultural Research (CGIAR) decided to accelerate, on a pilot and one-time only basis the preparation of up to three Challenge Programs (CPs) so that the System can explore ways of improving CP design and implementation. They are called Pilot Challenge Programs. The CGIAR also decided to initiate in 2002 the regular process for the design and development of challenge programs. They are called Regular Challenge Programs
