This map illustrates satellite-detected surface waters in Sofala province of Mozambique as observed from a Sentinel-1 image acquired on 26 January 2021 at 05:09 local time and using an automated analysis with Artificial Intelligence based methods. Within the analyzed area of about 15,500 km2 and, a total of about 1,000 km2 of lands appear to be flooded. The surface waters extent detected using the 26th of January 2021 image seems to be stable compared with the 25th of January 2021 observation. Based on Worldpop population data and the detected surface waters in the analyzed area, about 53,000 people are potentially exposed or living close to flooded areas for a total population about 1 million in this zone. About half of the potentially affected population area is located within Buzi district.
This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR-UNOSAT. Important Note: Flood analysis from radar images may underestimate the presence of standing waters in built-up areas and densely vegetated areas due to backscattering properties of the radar signal.
