Expert panel: 3ie's new food system Evidence Gap Map offers a roadmap of the field

Expert policymakers and researchers joined 3ie for a panel discussion on the new gap map, highlighting the ways it can be useful and the findings that surprised them.

This new evidence gap map shows what we know – and what we don't know – about food systems interventions

Right now, 690 million people are undernourished and at least 650 million people are obese. Given these staggering statistics, it is imperative that we use the best available evidence to improve nutrition and food security across the globe.

With a significant number of active cases globally, the novel coronavirus represents an extreme public health challenge. The outbreak of the pandemic has led to stringent travel restrictions, making data collection a highly challenging task for the development research community.
