Satellite Analysis Reveals Flood Extent in Botswana Districts as of March 2025

Satellite imagery from 4 March 2025 shows that approximately 7 km² is still affected by floodwaters in Gaborone, South East, and Kgatleng Districts, Botswana, reducing from 23 km² since late February. This analysis is preliminary and requires ground validation by UNOSAT.

On 4 March 2025, satellite imagerying enabled the detection of water extents in the Gaborone, South East, and Kgatleng Districts of Botswana. The information was derived from various satellites, including Sentinel-2, PlanetScope, and Kanopus-V, covering an area of approximately 700 km². The analysis revealed that around 7 km² remains inundated by floodwaters, which have receded by approximately 23 km² since the floods were last recorded on 23 and 25 February 2025.

It is important to note that this assessment is preliminary and has not been validated through on-site investigations. The United Nations Satellite Centre (UNOSAT) encourages ground feedback to enhance the accuracy of the data collected. Such feedback is crucial for confirming satellite observations and aiding future risk assessments.

The satellite analysis reveals that despite significant flooding in Gaborone, South East, and Kgatleng Districts, the water extent has characteristically decreased since late February 2025. The information provided is preliminary and stresses the importance of ground validation to confirm the data collected through satellite technology.
