Natural Resource Management (NRM) Research in the CGIAR faces three interlinked impact challenges. First the CGIAR needs to pursue NRM research that achieves reductions in poverty and hunger and does so at scale; second we need to understand how this happens more quickly and efficiently; and third we need to measure our outcomes and impacts so that we can demonstrate these achievements in an appropriately critical manner. In order to review these challenges and consider how the CGIAR might best address them through some of the CGIAR Research Programs (CRPs) a workshop was held in Penang 14-15 February, 2012, in conjunction with a parallel meeting of the Independent Science and Partnership Council (ISPC) Stripe Review panel reviewing NRM research in the CGIAR. This report is a documentation of the workshop process and outputs.
