Cambios en la partición de flujos de agua en el Chaco Árido al reemplazar bosques por pasturas

A study in San Luis, Argentina, comparing native dry forests and pastures found that replacing forests with pastures reduces direct precipitation interception and increases surface runoff and potential soil-level evaporation. These changes suggest a reduction in transpirable precipitation and a higher risk of water erosion.

• Pastures exhibit lower direct interception of precipitation compared to forests, with values of 0.35±0.13 mm per event versus 1.51±0.50 mm per event.
• Replacing forests with pastures increases surface runoff, particularly during large and intense precipitation events, where runoff rose from 0% in forests to approximately 28% in pastures.
• Pastures show higher potential evaporation at the soil level during summer (7.0±0.9 mm/day) compared to forests (4.4±0.9 mm/day).
• Deep drainage was null for both land covers, although pastures showed a vertical displacement of salts in the soil profile up to 2 meters deep.
• The transition from forest to pasture is expected to decrease the fraction of precipitation available for transpiration and increase the potential risk of water erosion.
