The Consultative Group on InternationalAgricultural Research (CGIAR) has been one of the mostsuccessful research-for-development organizations over thepast 40 years. The $11 billion invested by CGIAR donormembers in research conducted by the international Centersunder its umbrella has yielded many multiples of that sum ineconomic benefits to developing and emerging countries.Annual economic benefits of research on rice in Asia aloneare equivalent to the total investment made by CGIAR donorsover 4 decades, leaving aside benefits in other continentsand from other research conducted by CGIAR institutions. TheCGIAR‘s success is due in part to the way it was organized.The Group itself was an informal forum for dialogue amongdonor members about research priorities, investment options,and the continuing relevance and effectiveness of theinstitutions supported. The international centersconstituted the core of the CGIAR. Each was (and still is)an autonomous international organization governed by aninternational board. The Group and the Centers wereoriginally advised by the Technical Advisory Committee (TAC)of distinguished scientists from developing and developedcountries, each appointed as an individual. The Group’sactivities were facilitated by its Secretariat based at theWorld Bank in Washington, DC, and TAC’s activities byanother secretariat based at the food and agricultureorganization in Rome.
