Your contribution will make it possible for 3ie to continue generating high-quality evidence on what works (and what doesn’t) to solve some of the most pressing development issues of our time. We believe when rigorous evidence is available, accessible and used by decision-makers to inform their work, it can improve lives of millions of people globally.


A small monthly contribution will help us keep pace with the rapid changes of our times. You can either support 3ie directly or invest in some of our strategic initiatives to improve the evidence ecosystem.

Support the Development Evidence Portal

One such initiative is the Development Evidence Portal (DEP): an expansive and growing repository of rigorous evidence including impact evaluations, systematic reviews and evidence gap maps focused on L&MICs. Your contribution could help offset considerable costs we incur to ensure the portal is up to date and responsive to your evidence needs.

Users of our portal — from academia, government and international development organizations — rely on our portal to make their work easier.

The existence of 3ie’s DEP was an essential starting point for high-level discussions with German development organizations around strengthening the use of available high-quality evidence in project design. Since the DEP significantly reduces search time for relevant high-quality evidence, it was perceived as an important pillar for operationalizing evidence use in German development cooperation.
