The PeaceTech Toolbox.

Powerful resources to build and scale your peacebuilding mission.


PeaceTech Lab Lexicons.

PeaceTech Lab’s series of hate speech Lexicons identify and explain inflammatory language on social media while offering alternative words and phrases that can be used to prevent and stop the spread of hate speech in conflict-affected countries. Our Lexicons serve as a pivotal resource for local peacebuilders and organizations working to stop and prevent hate speech worldwide.

Esri Terrorist Attacks Storymap.


In recent years, an increasing number of terrorist attacks have shocked communities around the world, and many of the gravest attacks have occurred in countries like Nigeria, Kenya, Somalia, and Bangladesh, as well as in war-torn locales like Iraq, Syria, and Afghanistan.

The Terrorist Attacks Storymap, a collaboration between Esri Story Maps and PeaceTech Lab, uses crowdsourced data from Wikipedia to present a chronology of terrorist attacks around the globe. Wikipedia moderators include experts in the field of global conflict and terrorism, and the pages driving this story have been revised thousands of times since the start of 2016. As a result, the quality of the data on this map is constantly improving.

As with any crowdsourced data, the map may display spurious or objectionable data, for which Esri and PeaceTech Lab hold no responsibility. Similarly, the definition of terrorism is subjective and, in the case of this map, is determined by the contributing community.

If you dispute an event or observe grammatical errors or misspellings, we encourage you to submit revisions to Wikipedia via the “Improve the Map” button in the About section of the map. You can learn more about the Wikipedia editing process here.


The PeaceTech Wiki.

The PeaceTech Wiki is a free learning resource developed by PeaceTech Lab and the team of international technologists who support peacebuilders in our network. As we come across tools that can be used for positive social change, we share them on the Wiki to spread peacetech throughout the global peacebuilding community.


Blogs and Bullets.

PeaceTech Lab partnered with the United States Institute of Peace (USIP) to explore ways to use new analytical tools to understand the power of online discourse in both promoting and preventing violent conflict. We co-hosted six major conferences, four in Washington D.C. from 2010 - 2014 and two at Stanford University in 2011 and 2013.

These meetings brought together a wide range of leading academic and industry experts to evaluate the Arabic, Russian, and Persian language blogospheres and conduct research into the role of new media in contentious politics. The events were held in partnership with George Washington University, Harvard University’s Berkman Center for Internet & Society, and Morningside Analytics. PeaceTech Lab and USIP produced two papers that laid out a conceptual framework for analyzing the impact of media on conflict.
