This is the first review on the Systemwide Programme on Collective Action and Property Rights (CAPRI) convened at IFPRI. The review was commissioned by the Interim Science Council and was chaired by John Bruce from the World Bank. CAPRI was established in 1996 and is funded by Sweden, Norway, Italy and the Ford Foundation. The review found that : a) CAPRI's thematic foci are highly relevant to the CGIAR's goals of sustainably increasing food production through technology adoption, b) CAPRI has been effective in knowledge generation through commissioned papers and workshops, c) CAPRI has increased awareness by centres and NARS of the role of CA and PR research in natural resource management and technology adoption and d) CAPRI's governance and mode of operations have been successful. This report was discussed at the 83rd meeting of the interim Science Council held at IPGRI in August 2002.
