In Nigeria, 3iS strengthened the Rapid Response Mechanism (RRM) led by UNICEF by closing critical information management (IM) gaps in emergency response efforts. We developed a geospatial mapping system, improving spatial decision-making and intervention tracking for UNICEF and the other RRM partners in Nigeria. Additionally, we provided IM support, assessments, and training to RRM partners, enhancing their ability to respond effectively to humanitarian crises in the region.
