Short Summary

This study maps water-accessibility deficits across Ethiopia's Eastern and Southern Drought Belt by analyzing the spatial distribution of water points in relation to precipitation, soil moisture, and population density.

Objective

• Investigate the alignment between current water infrastructure placement and population needs in drought-prone regions of Ethiopia

Study Configuration

• Spatial Scale: Regional (Afar, Oromia, and Somali, three of the most drought-prone regions in Ethiopia)
• Temporal Scale: Not specified

Methodology and Data

• Models used: None mentioned
• Data sources:
  • CHIRPS precipitation data
  • FLDAS soil moisture data
  • WorldPop 2025 population count estimates
  • mWater dataset (water points)

Main Results

• Improved water points were distributed more evenly across soil moisture extremes, with 46.8% located in the wettest level and 25.1% in the driest class.
• Unimproved water points were concentrated in regions of high precipitation, with 53.9% located in the wettest level and 0% in the driest level.
• 65.7% of all water points were located in areas with low population density (1 to 5 people/100m grid).

Contributions

• This study provides a spatial analysis of water-accessibility deficits in drought-prone regions of Ethiopia, highlighting discrepancies between infrastructure placement and population needs.
