UN Operational Satellite Applications Programme (UNOSAT)**UNOSAT code FL20221019NGA** This map illustrates cumulative satellite-detected water using VIIRS in Nigeria between 1 to 25 October 2022 compared with the period from 1 to 30 September 2022. Within the cloud free analysed areas of about 912,000 km², a total of about 48,300 km² of land appears to be affected. In the analysed areas, 1,370 health facilities and 2,730 schools are identified to be within or close to a flooded zone. In comparison with the period between 1 to 30 September 2022, water extent appears to have increased of about 2,300 km². Based on Worldpop population data and the maximal flood water extent ~12,200,000 people are potentially exposed or living close to flooded areas amongst the 220 million people living in the analysed zone. This is a preliminary analysis and has not yet been validated in the field.
