The diversity of players in the field of agricultural (and, more generally, rural) policy and management research is sketched in a global overview of relevant research resources, and the small but important part played by the CGIAR Centres in this is explored, particularly where it has maximum value in terms of international public goods, and for strategic links to other parts of the CGIAR portfolio. The patchy and often slender (and perhaps diminishing in specific cases) capacity of national agricultural policy research and analysis units in the less‐developed world to deliver the needed research products is examined.
