Using Crowdsourcing to Map Displacement in South Sudan

Friday, April 14, 2017

FEWS NET is once again partnering with Tomnod to improve population information in five South Sudanese counties by using crowdsourcing to gather evidence-based food security analysis.

Through Tomnod, volunteers from around the world identify different elements such as buildings, tents, and livestock in satellite images that are hosted on Tomnod’s website. This approach creates data sets that can more accurately assess the level of food insecurity in South Sudan.

This approach will help FEWS NET’s work in South Sudan obtain more information where access to areas of acute food insecurity is limited. Read more about the most up to date FEWS NET report on South Sudan.


The Famine Early Warning Systems Network is a leading provider of early warning and analysis on food insecurity. Created by USAID in 1985 to help decision-makers plan for humanitarian crises, FEWS NET provides evidence-based analysis on some 34 countries. Implementing team members include NASA, NOAA, USDA, and USGS, along with Chemonics International Inc. and Kimetrica. Read more about our work.
