HOT's 'Community Mapping for a Resilient Bamako' project (2020-2022) trained residents to map flood-prone drains and waste sites using JOSM, OpenMapKit/ODK, Mapillary and QGIS, alongside a separate MapSwipe campaign in which over 100 local participants (45% women) logged 1,500+ volunteer hours across 6 million satellite imagery tiles — part of the World Bank's Africa Cash for Digital Work Program — to locate solid-waste dumps across more than 450 km² of the city.
