map UNOSAT

This map illustrates satellite-detected flood water extent in Somali Region, Ethiopia. The analysis was conducted by analysing a Sentinel-1 image acquired on the 7 May 2018. As observed from the satellite radar image, a total of 11,329 ha of land were inundated in the area of interest. By using WorldPop data, we estimate that at least 8,800 people are potentially affected or living close to the potentially flooded area. This corresponds to about 6% of the population living in the area of interest.

In the north-eastern section of the border town of Dolo there are 3 small concentrations of likely informal shelters, numbering 75 in total which were erected between 26 October 2010 and 17 July 2011. The average size of these probable shelters is relatively small (<10m2) and informally built on marginal land at the northern edge of town, and thus could represent locations of Somali refugees. This is a preliminary assessment and has not yet been validated in the field. Please send feedback to UNITAR/UNOSAT at the contact information below.
