At the recently concluded What Works Global Summit (WWGS) which 3ie co-sponsored, a significant number of the sessions featured presentations on new impact evaluations and systematic reviews. WWGS was a perfect opportunity to learn lessons about the demand for and supply of high-quality evidence for decision-making because it brought together a diverse set of stakeholders. There were donors, knowledge intermediaries, policymakers, programme managers, researchers and service providers.

In June this year, 3ie and the International Fund for Agricultural Development organised a workshop where we had several productive discussions around two key questions: Are impact evaluations answering policy-relevant questions and generating useful evidence? What are the challenges faced in designing and implementing impact evaluations of cash transfers and agricultural innovation programmes?
