The Extreme Citizen Science lab at University College London (UCL) has developed a participatory mapping project, "Crowdmapping for Food Security in Ethiopia," which aims to support communities in tackling pressing concerns of water scarcity, food insecurity, and conflict. The project uses human-centered design principles and co-designs tools with local people, enabling them to create their own maps and democratize geospatial analysis. The mobile app connected to the CARTO platform links local communities with varying levels of GIS expertise, allowing for simple spatial analysis and sharing data with other stakeholders. To overcome technical challenges such as limited internet access and electricity scarcity, the team uses locally stored data and provides solar chargers and power banks. The project also aims to promote open-data sharing from the ground-level knowledge of local communities, making a positive impact on people's lives by empowering them through geospatial data.
