Conversion to soy on the Amazonian agricultural frontier increases streamflow without affecting stormflow dynamics

Abstract: 20 21Large-scale soy agriculture in the southern Brazilian Amazon now rivals 22 deforestation for pasture as the region's predominant form of land use change. Such 23 landscape level change can have substantial consequences for local and regional 24 hydrology, which remain relatively unstudied. We examined how the conversion to soy 25 agriculture influences water balances and stormflows using stream discharge (water 26 yields) and the timing of discharge (stream hydrographs) in small (2.5 to 13.5 km 2 ) 27 for… Show more

“…Thus, our results reveal a soilscape wellbuffered with respect to near-surface hydrology in this part of Amazonia and underpin the findings of Hayhoe et al (2011) that the conversion to soybeans did not affect stormflow dynamics.…”

“…Mean annual temperature is 27°C and mean annual precipitation is 1,800 mm/yr (1987Tanguro Ranch, unpublished data), almost all of which falls from September to April. The landscape at Tanguro Ranch is undulating, with wide interfluves that grade to streams with generally less than 65 m in elevation change and channel slopes between 0.3° and 1.9° (Hayhoe et al 2011). The region lies in the headwaters of the Xingu River, the fifth largest tributary of the Amazon River by watershed size (basin area, 446,203 km 2 ; length, 1,640 km; average discharge, 8,665 m 3 /s).…”

“…Tertiary and Quaternary fluvial deposits cover Precambrian gneisses of the Xingu Complex (Projeto Radambrasil 1981). Topographic differences between plateaus and stream channels indicate the depth to the water table ranges from 20 to more than 40 m (Hayhoe et al 2011). The landscape at Tanguro Ranch is undulating, with wide interfluves that grade to streams with generally less than 65 m in elevation change and channel slopes between 0.3° and 1.9° (Hayhoe et al 2011).…”
