The 1992 Review of CGIAR Priorities and Strategies identified: strengthened human resources and institutions for greater research capacity in developing countries' research systems as one of the CGIAR's important aims. The diversity of NARS raises issues in the area of institution strengthening. The CGIAR may need a strategy to relate to the different systems, particularly the private sector elements. An issue for the Centres is how to set priorities and balance their support to the much broader and heterogenous set of bodies comprising the new NARS, It will be advantageous to identify the kinds of interventions the Centres can make and which elements of the NARS can be targeted with greatest effect or with least cost. Given the Centres' more diversified research portfolios, it will also be advantageous to choose which components of their programmes to extend to other partners.
