This scoping paper summarises a range of activities 3ie undertook to assess stakeholder demands and priorities for generating new impact evaluation evidence on how science, technology, innovation and partnerships accelerate development outcomes in low- and middle-income countries. We identify several important gaps in the evidence, such as the impacts of technology interventions that use biometrics and non-health-related innovative financing interventions. We also identify several sectors and themes that should be prioritised for new impact evaluations. They include impacts on crises and conflict and agriculture and food security outcomes. We also recommend that new impact evaluations conduct cost analysis. There are several clusters of studies that are promising for synthesis, including studies on mobile money systems, digital information services for agriculture and food security, and m-health interventions.
