This map illustrates satellite-detected surface waters over Niamey and Tillaberi regions in Niger as observed from Sentinel-2 image acquired on 10 Sep 2020. Within the analyzed area of about 1,400 km2, a total of about 90 km2 of lands appear to be flooded. Based on Worldpop population data and the detected surface waters, about 140,000 people are potentially exposed or living close to flooded areas. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR - UNOSAT.
