The Claim
In degraded pastures of the Brazilian savanna, higher vegetation cover is significantly associated with lower soil loss, with a strong inverse correlation (r = -0.80, p ≤ 0.05) and a determination coefficient (R²) of 0.64, indicating that vegetation cover explains 64% of the variation in soil erosion rates.
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.
The more plants covering the ground in damaged savanna pastures in Brazil, the less soil gets washed away — and plants explain a big chunk of why some areas lose more soil than others.
See the scientific wording
In degraded pastures of the Brazilian savanna, higher vegetation cover is associated with lower soil loss, showing a strong inverse correlation (r = -0.80, p ≤ 0.05) and a determination coefficient (R²) of 0.64, indicating that vegetation cover explains a substantial portion of the variation in soil erosion rates.
What the research says
1 studyStudy: Using geospatial analysis to detect soil loss in pasture in the Brazilian savanna (Cerrado)
The study found that where there's more plant cover in degraded savanna pastures, the soil is less likely to wash away, just as the claim says.
