Nigeria environment data

**ADAM ID: **FL-20250922-NGA-01 A flood occurred on Sep 22 2025 in Nigeria. It affected an estimated 1814776 people and 264965 ha of cropland. WFP’s Automated Disaster Analysis and Mapping (ADAM) system is an operational system for collecting, analysing and mapping geospatial and socio-economic information following sudden onset humanitarian emergencies.

GLIDEnumbers are GLobal unique IDEntifiers for Disasters. Each disaster is registered in a record that contains a GLIDEnumber that uniquely identifies it and allows information to be interoperable across multiple disaster information sources, both structured and textual. Accessing disaster information can be a time consuming and laborious task. Not only is data scattered but frequently identification of the disaster can be confusing in countries with many disaster events and across borders. To address both of these issues, Asian Disaster Reduction Center (ADRC) proposed a globally common Unique ID code for disasters. Among the institutions using actively GLIDEnumbers are UN-OCHA (ReliefWeb, FSCC, HDX), UNDRR, UNDP, WMO, IFRC, FAO, the European Commission and the Centre for Research on the Epidemiology of Disasters (CRED), among many others. Country datasets are only produced for countries with at least one GLIDE event since 1 January 2022. The global dataset contains all events available from the GLIDE API, including those not assigned to a country.

**UNOSAT code: FL20240902NGA, GDACS ID: 1102720** This application provides flood impact assessments for Nigeria in September 2024.

**UNOSAT code: FL20250601NGA, GDACS ID: 1103303** This map illustrates the satellite-detected water extent in Mokwa Town, Niger Local Government Area, Niger State, Nigeria as observed from a GeoEye-1 imagery acquired on 2 June 2025 at 11:24 local time. Within the analysed area of approximately 100 km², an estimated 1.5 km² of land appears to be affected by floodwaters. UNOSAT has identified within this area 470 damaged structures and 199 potentially affected structures. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to the United Nations Satellite Centre (UNOSAT).
