The Claim
In the Ribeirão Serra Negra Watershed of the Brazilian savanna, soil loss is most prevalent in moderately and severely degraded pasture areas, with 82.46% (5,683.19 hectares) of the land experiencing measurable erosion, and the most common erosion rate occurring between 20 and 40 Mg per hectare per year, covering 61.98% of the affected area.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Most of the eroded land in a Brazilian savanna watershed is in damaged pasture areas, and the biggest chunk of that land loses soil at a rate of 20 to 40 tons per hectare every year.

What the research says
1 studyStudy: Using geospatial analysis to detect soil loss in pasture in the Brazilian savanna (Cerrado)
The study looked at how much soil is washing away from damaged pasture land in a specific part of Brazil, and found exactly what the claim says: most of the land is somewhat to badly damaged, and that’s where most of the soil loss happens.
