Abstract

Regional effects of farming on hydrology are associated mostly with irrigation. In this work, we show how rainfed agriculture can also leave large-scale imprints. The extent and speed of farming expansion across the South American plains over the past four decades provide an unprecedented case of the effects of rainfed farming on hydrology. Remote sensing analysis shows that as annual crops replaced native vegetation and pastures, floods gradually doubled their coverage, increasing their sensitivity to precipitation. Groundwater shifted from deep (12 to 6 meters) to shallow (4 to 0 meters) states, reducing drawdown levels. Field studies and simulations suggest that declining rooting depths and evapotranspiration in croplands are the causes of this hydrological transformation. These findings show the escalating flooding risks associated with rainfed agriculture expansion at subcontinental and decadal scales.

Abstract

Las regiones áridas tienen déficit hídrico a lo largo de todo el año, lo cual limita el crecimiento de la vegetación y la provisión de agua para bebida animal. El Chaco Árido (~10 Mha) sostiene una producción ganadera extensiva de baja inversión, basada en cosechar agua de lluvia en represas (tajamares) como principal fuente de abastecimiento de agua. En este trabajo se determinó la distribución espacial de las represas y su relación con el entorno biofísico (precipitación, vegetación, caminos) en el Chaco Árido. Para ello analizamos imágenes satelitales, información vectorial y análisis multivariados sobre una grilla de 135 celdas de 0.25°x0.25° cada una. En total identificamos 7920 represas (1 cada 1230 ha) y observamos densidades máximas de 1 represa cada 185 ha, pero también celdas sin represas, asociadas a la presencia de sierras, salinas y dunas. La densidad de represas fue mayor en celdas con mayor densidad de establecimientos ganaderos, caminos y carga animal (r=0.63, r=0.56 y r=0.51, respectivamente; P

Abstract

• Ligustrum lucidum tree invasion alters the water balance in a seasonally dry forest. • Runoff was almost nil in both native and L. lucidum forest stands. • L. lucidum forest showed higher annual evapotranspiration rates than native forest. • L. lucidum forest showed drier soil profiles, particularly in the deepest soil layers. Plant invasion is one of the major global environmental threats with the potential to alter the ecosystem stability and functioning. In water-limited ecosystems, the impacts of non-native invasive trees on the water balance are particularly relevant since they can compromise the use of water by native taxa of the ecosystem and water provision for humans. In this paper, we assessed the hydrological impacts of the Ligustrum lucidum (Chinese glossy privet) invasion on a mountain seasonally dry forest of the Chaco region (Central Argentina). More specifically, we determined volumetric soil water content, runoff, and actual evapotranspiration, and their relations to the size of rainfall events in native forest stands and its adjacent invaded stands. We combined three-years field measurements and remote sensing data. L. lucidum stands showed less water content through the soil profiles than the native forest (0–70 cm depth; 19.6 and 23.1 %, respectively), particularly during the dry conditions. The drier condition in the deeper soil layers compared to the upper ones in the invaded stands indicated less rainwater percolation throughout the soil profile over the year, independently of the magnitude of the rainfall events. Daily variation of deep-water content (60–70 cm depth), only observed in L. lucidum stands, showed nightly increase and day-time decrease in dry conditions. Runoff was similar and almost nil in both native and invaded forests, even after large rainfall events (>30 mm). L. lucidum stands showed ∼ 18% higher annual actual evapotranspiration rates than native stands. Based on our results, relatively higher water consumption for mono-specific L. lucidum stands in periods when photosynthetic activity of multi-specific native dry forest is still low may represent a competitive advantage in terms of plant invasion, and at the same time it generates negative impacts on water resources, reducing soil water content and limiting deep-water recharge in a water-limited ecosystem.

Abstract

In arid Patagonia grazing by livestock is the most widespread form of land use. Although grazing is known to affect soils hydrological characteristics, few studies have addressed runoff flows generation as influenced by cattle grazing in these areas. In this study, we evaluated the relationship between grassland condition and hillside surface characteristics that influence the response to rainfall. We compared landscape characteristics, landscape function indices and soil properties of bare soil (uncovered) interpatches at different slope positions with two degradation conditions and monitored interpatch moisture content during a rainy season. Severe degradation was associated with greater surface runoff, suggesting downslope resource transport. In the most severely degraded soils the upper slope showed a the lowest profile depth, greatest resistance to penetration and slowest infiltration rate, and the lower slope registered the second highest degree of saturation after rainfall events. These differences in hydrological properties would have also modified vegetation behavior as indicated by the NDVI. These results support the premise that the hydrologic response on arid zones slopes depends on the functionality of bare soil interpatches and on the previous moisture content.
