Initial soil moisture conditions dominate variation in event-scale propagation time from meteorological to agricultural drought

Agricultural Water Management
Agricultural drought, typically triggered by meteorological drought, poses a significant threat to crop production and regional water resources. Understanding the propagation from meteorological to agricultural drought is therefore crucial for improving ...

Evaluation of Soil Moisture Retrieval from the ERS and Metop Scatterometers in the Lower Mekong Basin [PDF]

, 2013
The natural environment and livelihoods in the Lower Mekong Basin (LMB) are significantly affected by the annual hydrological cycle. Monitoring of soil moisture as a key variable in the hydrological cycle is of great interest in a number of Hydrological ...

Cascading droughts: Exploring global propagation of meteorological to hydrological droughts (1971–2001)

Science of The Total Environment
An understanding of the spatiotemporal behaviour of Meteorological drought (MD) and Hydrological drought (HD) is crucial for analysing how drought propagation occurs. Here, drought events were treated as three-dimensional grid structures spanning space (latitude and longitude) and time.

Introgressed Variation in TaMYB7‐A1 Drives Graded Dormancy and Climate‐Adaptive Pre‐Harvest Sprouting Resistance in Wheat

Advanced Science, EarlyView.
TaMYB7‐A1 directly activates TaABI5 to enhance ABA signaling and regulate ABA‐GA homeostasis, enforcing seed dormancy. Its superior allele, derived from wild einkorn introgression, harbors a MITE insertion that elevates expression and two amino acid substitutions that enhance transcriptional activity, collectively generating graded PHS resistance for ...

Temperature Sensitivity and Adaptation of Cereal Yields: Empirical Evidence From Italy

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This paper investigates the evolving temperature sensitivity and climate adaptation of cereal yields in Italy from 1952 to 2023, using province‐level data for maize, common wheat, and durum wheat. Employing panel data econometric methods, we estimate yield responses to heat exposure, changes in sensitivity over time, and adaptation to climate ...

On the key role of droughts in the dynamics of summer fires in Mediterranean Europe [PDF]

, 2017
Summer fires frequently rage across Mediterranean Europe, often intensified by high temperatures and droughts. According to the state-of-the-art regional fire risk projections, in forthcoming decades climate effects are expected to become stronger and ...

Mechanisms of meteorological drought propagation to agricultural drought in China: insights from causality chain

npj Natural Hazards
Previous studies have overlooked the nonlinear dependency of drought propagation, limiting our understanding of its mechanisms. By establishing a causality chain, this study identifies the nonlinear propagation pathways of meteorological drought to ...
