Water Resources Research, 2018 It is difficult to predict and track the propagation of a hydrological drought because it is hard to determine its propagation speed. We propose a useful framework for calculating the hydrological drought instantaneous propagation speed which includes ...

Hydrological drought propagation and societal feedbacks in the Incomati River basin
, 2020 Human influences have become an important part in the drivers of drought in the Anthropocene. Activities such as land use change, damming of rivers, expansion of irrigated agriculture and the cultivation of high water consuming exotic trees can modify ...

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies
Advanced Science, EarlyView.This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

Using SIMGRO for drought analysis – as demonstrated for the Taquari Basin, Brazil [PDF]
, 2010 Tools were developed and tested to quantify space–time development of droughts at the river basin scale. The spatial development of a hydrological drought in river basins brings different challenges to describe drought characteristics, such as: area in a

Advanced Science, EarlyView.Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...

When the River Runs Low: Heterogeneous Impacts of Transportation Disruptions on Local Grain Basis
Agribusiness, EarlyView.ABSTRACT A substantial share of U.S. soybean and corn exports from the Midwest moves by barge along the Mississippi River system to export terminals in the Louisiana Gulf. Transportation costs between Midwestern grain elevators and export terminals create a wedge between prices at these locations, and shocks to these costs are partially passed on to ...

Assessment of hydrological droughts for the Yellow River, China, using copulas
, 2010 Droughts are one of the normal and recurrent climatic phenomena on Earth. However, recurring prolonged droughts have caused far-reaching and diverse impacts because of water deficits. This study aims to investigate the hydrological droughts of the Yellow
