Article
La precipitación es determinante de múltiples procesos en zonas áridas. Abordar su variabilidad es difícil en áreas extensas y de baja densidad de registros como la Patagonia norte. El objetivo de este trabajo es caracterizar la variación temporal y espacial de las precipitaciones, y evaluar productos satelitales de lluvia para esta región. Con los...
Article
In humid plains with shallow water-tables, vegetation and groundwater influence each other through different mechanisms. Therefore, agricultural management decisions, such as the selection of the crop rotation, can affect water-table levels and these, in turn, can affect the crop performance. In this work, we evaluated the effect of different crop...
Article
The establishment of tree plantations on native grasslands is expanding in Argentina and Uruguay, prometed by public incentives and, likely, by an emerging market of carbon sequestration. We assessed how this transformation affects the production of ecosystem goods and services, synthesizing preexisting and original information on their influence o...

Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we...
Article
Full-text available
Our understanding of how groundwater mediates evapotranspiration/streamflow partitioning is still fragmented and catchment studies under changing vegetation conditions can provide a useful frame for integration. We explored this partition in a flat sedimentary dry catchment in central Argentina in which the replacement of native vegetation with rai...

We synthesize research on the magnitude and dynamisms of salt stocks in the Chaco-Pampas. While current soil maps characterize one-fourth of the region’s soils as saline; integrated soil-hydrology-vegetation studies show salinity to be more widespread and dynamic due to the presence of shallow and stagnant groundwater systems. Two salt retention me...

Article
Hosting the flattest sedimentary plains and highest Andean range of the continent, southern South America faces hydrological transformations driven by climate and land use changes. Although water stable isotopes can help understand these transformations, regional synthesis on their composition is lacking. We compiled for the first time a dataset of...
Data
The data presented here comprises the stable isotopic composition (δ2H and δ18O) of 1659 samples of precipitation, rivers, groundwater and lakes/ponds samples from a total of 511 sites. This is a composite dataset that includes data from the Global Network of Isotopes in Precipitation (GNIP) and Rivers (GNIR) databases (IAEA/WMO 2019), data extract...
Article
The dry forests of South America are a key player of the global carbon cycle and the regional water cycle but they are being intensively deforested. We used eddy covariance measurements to compare the temporal patterns of CO2 and water vapor fluxes and their relationships with environmental variables in dry forest and pastures sites of central Arge...

Soil evaporation is a dominant water flux of flat dry ecosystems, reducing available water for plant transpiration. Vegetation plays a key role at controlling evaporation, especially by altering soil surface micro-meteorological conditions. Here we explored the vegetation cover effect on soil evaporation, differentiating the effects of canopy cover...
Article
Full-text available
During the last century the massive conversion of Australian dry forests to crops and pastures triggered the massive soil and groundwater degradation process known as dryland salinity. Currently, South American Chaco's dry forests are undergoing a similar transformation, leading global deforestation rates. The goal of this study was to review exist...
Article
Very alkaline environments exceeding calcite buffering are globally rare but conspicuous in many sedimentary plains of the World. While the deleterious effects of high alkalinity on soils are well understood, less agreement exists on its causes. We revise these causes to understand these exceptional environments and explain the pervasiveness of cal...
Article
Deforestation affects climate and the energy balance of the Earth not only through the release of greenhouse gases but also through shifts in the physical properties of the surface. These physical effects can be strongly dependent not only on the deforestation event but on the land use choices and management that follow it. Here we explored how the...

Full-text available
The semiarid Chaco plains present one of the highest rates of forest clearing and agricultural expansion of the world. In other semiarid plains, such massive vegetation replacements initiated a groundwater recharge and salt mobilization process that, after decades, raised regional water tables and salts to the surface, degrading agricultural and na...
Article
In this paper we explored how aridity influences the regional deforestation and land-use patterns (i.e. crops/pastures) in South American Dry Chaco. To do this, we contrasted land use during last decade (2001–2012) with a spatially explicit aridity index, which we complemented with a crop water balance model. Land-use classifications were performed...

In the province of Entre Rios (Argentina) rainfall has high impact on both agriculture and other economic and social sectors. Rainfall has a great variability and satellite products contain uncertainty in their values, so it is necessary to compare the satellite estimates with ground rain gauge measurements to evaluate the performance at local and...
Article
While most landscapes respond to extreme rainfalls with increased surface water outflows, very flat and poorly drained ones have little capacity to do this and their most common responses include (i) increased water storage leading to rising water tables and floods, (ii) increased evaporative water losses and, after reaching high levels of storage,...

In flat sedimentary plains in areas with a sub-humid climate, tree planting on grasslands and arable lands creates strong hydrological shifts. As a result of deep rooting and high water uptake of trees, groundwater levels drop and subsurface salt accumulation increases. Tree planting has expanded globally and in Hungary it reached rates of 15 000 h...
Article
Full-text available
A vast body of literature demonstrated that anthropogenic disturbances such as overgrazing and fire are key drivers of abrupt transition between vegetation types in ecosystems. In this study, we propose that the hydrological context (described in terms of rainfall, evapotranspiration and water yield) is a first-order, primordial determinant of the...

In arid regions throughout the world, shallow phreatic aquifers feed natural oases of much higher productivity than would be expected solely from local rainfall. In South America, the presence of well-developed Prosopis flexuosa woodlands in the Monte Desert region east of the Andes has puzzled scientists for decades. Today these woodlands provide...
Article
s u m m a r y Besides precipitation inputs, evapotranspiration of irrigated and natural oases, i.e. riparian and phreato-phytic ecosystems, of rain-shadow deserts is strongly influenced by lateral water inputs supplied by mountain rivers and foothill-recharged aquifers. A better understanding of these supplies and their imprint on the water consump...
Article
The increasing global demand for agricultural commodities is rapidly transforming land cover in South America. In central Argentina, vast tracts of natural woodland and grassland ecosystems are converted each year primarily for a larger share of the world's soybean market. Invisible to land-owners, policy makers and many others alike, these land-co...
Article
Throughout the world, shallow groundwater systems subsidize much higher net primary productivity (NPP) than would be expected based solely on local rainfall. Such subsidies are far more prevalent and less recognized in upland systems than in more commonly studied riparian ones. We present a quantitative framework for examining and quantifying groun...
Article
Evaporative groundwater discharge is, in most landscapes, restricted to riparian zones or depressions, yet, it can be a widespread hydrological feature of flat sedimentary regions with (sub)humid climate. We explored the interactive effects of climate, vegetation, and human decisions controlling evaporative discharge from shallow groundwater throug...
