Implication

Randomized trial assesses soil erosion using GIS and RUSLE in Wolaita zone, indicating urgent conservation needs.

Key Points

  • This research aims to analyze soil erosion rates and spatial distribution in the Wolaita zone using the RUSLE model integrated with GIS and remote sensing.
  • Utilized the RUSLE model for soil erosion assessment within ArcGIS 10.8.2 software.
  • Collected input datasets from NASA, FAO, USGS, and ESA for comprehensive analysis.
  • Identified erosion hotspots based on spatial distribution of annual soil loss rates.
  • Approximately 43,890.3 ha (9.77%) experienced high soil erosion, while 30,388.14 ha (6.76%) faced very high and 1,459.17 ha (0.32%) severe erosion.
  • Annual soil erosion rate varied from 0.18 to 486 tons ha -1 year -1, with peak erosion intensity in western areas at 46.09 to 486 tons ha -1 year -1.
  • Findings support effective conservation practices including contour farming and agroforestry for high erosion zones.
