The Haihe river basin (HRB) in the North China has been experiencing prolonged, severe droughts in recent years that are accompanied by precipitation deficits and vegetation wilting. This paper analyzed the water deficits related to spatiotemporal variability of three variables of the gravity recovery and climate experiment (GRACE) derived terrestrial water storage (TWS) data, precipitation, an...

Drought and salinity are two major abiotic stresses, similarly and/or differently affecting physiological processes of wheat. The aim of this study was to evaluate and compare the impacts of drought and salinity on wheat. A pot experiment was conducted as completely randomized design with three replications in the research greenhouse of Yasouj University in 2015. Treatments included different l...

Thymus with more than 200 species is known for its medicinal and culinary uses. There is an increasing demand for thyme and its products, requiring cultivation under different conditions, including drought. To understand the response of thyme to water deficit and its variation across the genus, eleven populations from a range of species (Thymus daenensis, T. kotchyanous, T. vulgaris, T. serpyll...

Drought management depends on indicators to detect drought conditions, and triggers to activate drought responses. But determining those indicators and triggers presents challenges. Indicators often lack spatial and temporal transferability, comparability among scales, and relevance to critical drought impacts. Triggers often lack statistical integrity, consistency among drought categories, and...

This study analyzes the impact of droughts, compared with average climatic conditions, on the supporting ecosystem service water provision in sub-watersheds in managed alpine grasslands in two climatically different regions of the Alps, Lautaret (French Alps) and Stubai (Austrian Alps). Soil moisture was modelled in the range of 0-0.3 m. At both sites, current patterns showed that the mean seas...

Drought is one of major environmental determinants of plant growth and productivity. Alfalfa (Medicago sativa) is a legume perennial forage crop native to the arid and semi-arid environment, which is an ideal candidate to study the biochemical and molecular mechanisms conferring drought resistance in plants. In this study, drought stress responses of two alfalfa varieties, Longdong and Algonqui...
