Accumulated satellite-detected water extents in Gaborone, South East and Kgatleng Districts, Botswana as of 4 March 2025

**UNOSAT code: FL20250220BWA, GDACS ID: 1103128** This map illustrates the satellite-detected accumulated flood extent in Gaborone, South East District, Botswana, as observed from Planet imagery acquired on 23 February 2025. Within the analyzed area of approximately 120 km², about 10 km² of land appears to be affected by floodwaters. UNITAR-UNOSAT has identified approximately 670 potentially affected structures within the analyzed area. 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).

**UNOSAT code: FL20250220BWA, GDACS ID: 1103128** This map illustrates the satellite-detected accumulated flood extent in Gaborone, South East District, Botswana, as observed from Planet imagery and very high-resolution Pleiades imagery acquired between 23 and 25 February 2025. Within the analyzed area of approximately 700 km², an estimated 30 km² appears to be affected by floodwaters. UNITAR-UNOSAT has identified around 900 potentially affected structures, along with 24 affected road segments and 10 affected bridges within the analyzed area. 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).

**UNOSAT code: TC20240313MOZ, GDACS ID: 1001053** This map illustrates satellite detected surface waters in Maputo province, Mozambique, as observed from a Sentinel-1 images acquired on 27 March 2024 at 18:23 local time (16:23 UTC). Within the analyzed areas of about 2,000 km², a total of about 45 km² of lands appear to be flooded. 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). 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.

This map illustrates satellite-detected flood waters over Save River in Mozambique as observed from the Radarsat-2 images acquired on 17 February 2017 and 05 February 2017. A decrease of surface waters was observed in the 17 February 2017 image compared to the 05 February 2017 image along the Save river. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks and within built-up urban areas because of the special characteristics of the satellite data used. This is a preliminary analysis and has not yet been validated in the field. Please send ground feedback to UNITAR UNOSAT.

**UNOSAT code: TC20240313MOZ, GDACS ID: 1001053** This map illustrates satellite detected surface waters in Gaza and Maputo provinces, Mozambique, as observed from a Sentinel-1 images acquired on 16 March 2024 at 05:19 local time (03:19 UTC). Within the analyzed areas of about 5000 km², a total of about 67 km² of lands appear to be flooded. This is a preliminary analysis and has not yet been validated in the field.
