Remote Sensing for Irrigation Water Management—The State of the Art and Prospects for Near‐Future Operations

Irrigation and Drainage, EarlyView.
ABSTRACT A recent UN report describes many regions as facing ‘water bankruptcy,’ a condition in which available water resources can no longer meet existing demands. In practice, this means irrigation will likely bear the greatest burden of future water‐use reductions, a complicated and fraught decision to make given its critical role in food security ...

Transforming Agricultural Water Management for Healthy People and Planet: Thinking Beyond Water

Irrigation and Drainage, EarlyView.
ABSTRACT This paper develops the concept of Thinking Beyond Water, a transdisciplinary paradigm that reframes agricultural water management (AWM) as a systems catalyst for planetary health, equity, justice and resilience. Moving beyond conventional irrigation‐centric models, we reimagine AWM through integrative frameworks such as the planetary ...

Construction and Application of a Novel C‐Vine Copula‐Based Multi‐Variate Ecological Drought Index

Irrigation and Drainage, EarlyView.
ABSTRACT A comprehensive ecological drought index capturing vegetation growth conditions and meteorological–hydrological variability is essential for assessing ecological drought and optimizing water resource management. This study selected soil moisture (SM), actual evapotranspiration (ET), land surface temperature (LST) and leaf area index (LAI) to ...

Chromium isotopic insights into early solar system evolution and origin of terrestrial planets

Etude isotopique du chrome : implications pour l'évolution du système solaire précoce et l'origine des planètes terrestres Les isotopes du chrome (Cr) jouent un rôle important dans la cosmochimie et les sciences planétaires car ce sont de puissants outils pour dater (chronométrie de courte période 53Mn-53Cr), tracer (anomalies ...

Downscaling of Temperatures Over the Eastern Mediterranean for the 21st Century

International Journal of Climatology, EarlyView.
We developed an analogue‐based statistical downscaling method, using a K‐nearest‐neighbour framework, to project daily maximum temperature (Tmax) and minimum temperature (Tmin) at 32 homogenized meteorological stations. Late twenty‐first‐century (2080–2100) temperature projections obtained using the method, show robust warming across all stations and ...

Machine Learning‐Based Correction of Reanalysis Surface Radiation Fluxes Using Ground‐Measured Data in the Southern Brazilian Pampa Biome

International Journal of Climatology, EarlyView.
This study demonstrates that ERA5 provides more accurate surface radiation flux estimates than MERRA2 across the Southern Brazilian Pampa. Machine learning models, particularly Random Forest, further improved the precision of reanalysis data for climate applications.

The influence of the sun/host star on atmospheric evolution and the habitability of terrestrial planets : assessing planetary habitability and its requirements in the solar system and on galactic scales

, 2022
The evolution and stability of planetary atmospheres is strongly correlated with the host star. The X-ray and extreme ultraviolet flux of the star that is absorbed in the thermosphere of terrestrial planets, shapes their stability and is the main driver of thermal escape mechanisms.

Southern Portugal hydroclimate of the last millennium from near‐annually resolved speleothem records

Journal of Quaternary Science, EarlyView.
ABSTRACT Hydroclimate in Portugal is influenced by the North Atlantic subtropical high‐pressure system (the Azores High) and by internal climate modes, most prominently the North Atlantic Oscillation, which may shift in position and/or intensity due to anthropogenic climate change.

Late Quaternary lake filling and drying in northern Australia's largest freshwater lake

Journal of Quaternary Science, EarlyView.
ABSTRACT Lake Woods, Jurrkulu, is northern Australia's largest freshwater lake filled today in strong Indo–Australian summer monsoons (IASM) to maximum depths of ~5 m. On the western margins of the lake, two large arcuate ridges occur 20 to 40 m above the lake floor and inset within these are other mid‐elevation lake deposits, such as depositional ...
