Impact assessment of IPM technology implementation

As the IPM CRSP has grown, impact assessment has been an integral part. Basic assessment techniques are used ex-ante to identify crops, pests, and technologies that will yield the biggest impacts. These areas were then prioritized for research. Over time, these ex-ante techniques have been refined to enable targeting of impacts towards women and other disadvantaged groups, such as the poor.  As technologies have been generated and adoption spreads, information on yield and cost changes from field level IPM trials have been combined with expected technology spread to estimate the impacts of the research itself. These impacts have been substantial. The new frontier in IPM impact assessment is to measure ex-post impacts by comparing observed household- and market-level outcomes to what would have been observed in the absence of the research investment.
