Groundwater plays a crucial role in meeting both human and ecosystem water needs. Its importance is expected to grow due to increasing water demand and the impacts of climate change on surface water resources, particularly in the Southern Hemisphere, where irrigated agricultural expansion continues to intensify. However, limitations in the spatio-t...

Agricultural expansion in the Brazilian Cerrado ecoregion has been causing extensive land use and land cover changes (LULCC), drastically shifting the carbon cycle dynamics of the affected ecosystems. However, accurate in situ observations of the net ecosystem exchange of carbon dioxide (NEE) from wooded Cerrado (Cerrado sensu stricto) as well as f...

The Cerrado sensu stricto, so‐called wooded Cerrado, is one of the many phytophysiognomies of the undisturbed Brazilian Cerrado ecoregion holding a biodiversity hotspot towards an extensive area. Thus, such land is under constant land use and cover changes mainly due to the demand for agriculture land, sector with the highest consumption of availab...

Severe droughts have historically plagued Brazil’s semi-arid region, leading to mass migrations and significant loss of life. Although these events have sparked a unique coevolutionary relationship between humans and water systems in this region, this historical narrative remains largely unexplored from a hydrological point of view. This study delv...

River-aquifer interactions have significant implications for water resources management, as they play pivotal roles in sustaining healthy river ecosystems and driving biogeochemical cycles. In Brazil, despite localized research efforts, a comprehensive understanding of these interactions on a national scale remains elusive, mainly due to the scarci...

River-aquifer interactions play a crucial role in water availability, influencing environmental flows and impacting climate dynamics. Where groundwater tables lie below river water levels, stream water can infiltrate into the underlying aquifer, reducing streamflow. However, the prevalence of these “losing” rivers remains poorly understood due to l...

Heatwaves pose significant threats to socioeconomic and environmental systems, with their intensity and frequency expected to increase due to climate change. Despite their critical impacts, future heatwaves in Brazil remain underexplored, especially from a human-perceived perspective, which is crucial for assessing potential public health impacts....

The Brazilian Savanna (Cerrado) is the second‐largest South American biome that corresponds to almost two‐third of the national agricultural production. Extensive agricultural‐driven land‐use changes have significantly altered the landscape, causing increased soil erosion. Furthermore, projections of climate change effects on the Cerrado raise conc...

Changes in land cover and land use (LULC) are one of the main drivers of erosion and runoff. How ever, most research has relied on short-term observations and only focused on one or two land cover types. We investigated the long-term trade-off between common agricultural land covers (sugarcane, pasture, and soybean), runoff, and soil loss rates. We...

In recent decades, distributed temperature sensing (DTS) has emerged as a robust technology for environmental applications, enabling high-resolution temperature measurements along fibre optic cables (FOCs).

Introduction: Runoff measurement and monitoring is a laborious, time-consuming, and costly task. Additionally, common runoff monitoring usually primarily provide water level, requiring information on the stage-discharge relation. Automatic equipment such as flow meter tipping bucket (TB) is a potential option to simplify and provide continuous runo...
