28,600 volunteers from 147 countries took part in analysing 326,000 square kilometers of satellite imagery to identify Darfur’s most remote villages

About Next Project


Using their computers and phones, 28,600 Decoders contributed more than 9,000 hours to map remote and vulnerable villages in Darfur

In 2016, Amnesty International published credible evidence that countless villages in Darfur have been attacked by the Sudanese government and its allied militias. People have been shot while fleeing, raped, and even targeted with chemical weapons.

Decode Darfur was a project launched in October 2016 that asked volunteers to identify and map over 326,000 square kilometers of satellite images to identify more of these remote and vulnerable villages.

As a results, we 326,000 square kilometers of satellite imagery in Darfur. These findings provided the basis for our next project, Decode the Difference, where we asked our Decoders to compare images of the same village and look for evidence of attacks, by helping us identify significant change in buildings and structures over time.

Help us show the international community that it has ignored Darfur for too long.


Decode Darfur was the second project for the Amnesty Decoders - a global network of digital volunteers for human rights research. Already there are more than 30,000 volunteers from more than 150 countries.

This project was developed in collaboration with Open Data Kosovo, Focal Labs and The Engine Room, with financial support from the Swedish Postcode Lottery. Powered by PyBossa, an open source crowdsourcing framework to analyse data that can't be processed by machines alone

Amnesty International would like to thank all the volunteers who have helped so far with this project. We’d also like to say a very special thank you to those volunteers who helped out as moderators on the discussion forum. We couldn't have done it without you.

In particular we'd like to thank SBE, voz, Walter, JoostV, Dekker, yvesprigent, Sietse, hanny123, ellen-2016, anon2034, SarahN, Birdseye, Geromy, Max_B, Akkie, Ingewiel, Aiud, mohamedahmed, and many others who decoded hundreds of thousands of square kilometers of satellite images, and who participated in hundreds of conversations.
