Global Soil Degradation Severity Assessment

GLASOD provides a global assessment of human-induced soil degradation severity. The dataset classifies degradation on a scale from 1 (low) to 4 (very high) using a methodology developed by ISRIC. It was compiled by the CEOS_EXTRA organization and published in 1990.

Use Cases

• Map global soil degradation severity using the provided polygon-level severity classification.
• Analyze regional patterns of land degradation by correlating severity scores with other environmental datasets.
• Establish a 1990s baseline for soil health by examining the distribution of severity levels from 1 to 4.

Strengths

• Global spatial coverage of soil degradation assessment.
• Provides a standardized severity classification from 1 to 4 created by ISRIC.

Limitations

• Data is from 1990 and does not reflect current conditions.
• The severity classification is intended for mapping only, not for precise area calculations.
