The Development Evidence Portal (DEP) is the world’s largest database of impact evaluations and systematic reviews on interventions to improve lives in low- and middle-income countries. It is updated monthly and contains more than 10,000 impact evaluations, systematic reviews and evidence gap maps. The DEP provides advanced searching capabilities and a rich set of options for filtering studies to help you find the evidence you need.

A process evaluation can serve several purposes. It can be used to strengthen the impact evaluation design, it can help improve project implementation, and it can provide recommendations on how to improve the design and implementation of future projects. This blog by 3ie Senior Research Fellow Michael Bamberger is the first in a two-part series that looks at different process evaluation approaches and the benefits of using process evaluation.

We have identified 82 new studies as part of our second update to 3ie's living Food Systems and Nutrition Evidence Gap Map, originally published in early 2021. This blog underscores the interventions new research focuses on and the evidence gaps it tries to address in this rapidly-changing field.
