An assessment of the ability of Bartlett–Lewis type of rainfall models to reproduce drought statistics [PDF]

, 2013
Of all natural disasters, the economic and environmental consequences of droughts are among the highest because of their longevity and widespread spatial extent. Because of their extreme behaviour, studying droughts generally requires long time series of

High risk of growth cessation of planted larch under extreme drought

Environmental Research Letters, 2021
Larch trees are widely used in afforestation and timber plantations. Yet, little is known on how planted larch trees cope with increasing drought. We used a tree-ring network of 818 trees from 31 plantations spanning most of the distribution of Larix ...

Resistance and resilience of a semi-arid grassland to multi-year extreme drought

Ecological Indicators, 2021
Globally, extreme droughts are likely to become more frequent, more intense, and longer in duration with climate change. Understanding the impacts of drought on ecosystem function (i.e., resistance) and its recovery after drought (i.e., resilience) is ...

Spatial and temporal analysis of drought in Manjalar sub-basin of Vaigai in Tamil Nadu using standardized precipitation index [PDF]

, 2016
Drought is universally acknowledged as a phenomenon associated with scarcity of water. Drought characterization is essential for drought management operations. Using drought indices is a pragmatic way to assimilate large amounts of data into quantitative

Ecosystem Resistance and Resilience after Dry and Wet Events across Central Asia Based on Remote Sensing Data

Remote Sensing, 2023
Climate change forecasts indicate that the frequency and intensity of extreme climate events will increase in the future; these changes will have important effects on ecosystem stability and function.

Adapting agriculture to drought and extreme events [PDF]

Journal of Soil and Water Conservation, 2012
T he 2012 drought, one of the worst during the last 80 years or more, reminds us of the dust bowl of the 1930s (figure 1) and indicates that climate change is a reality rather than a distant threat. The drought has had a severe impact on yields, reducing the predicted grain production for corn per acre at a farm level to levels of production that have ...

Hydrometeorological Extreme Events in West Africa: Droughts

Surveys in Geophysics, 2022
AbstractWest African rainfall is an important part of the global climate system that influences the Atlantic thermohaline circulation, hurricane activities, and dust transport. The water cycle is linked to the monsoon and its interannual to decadal variations.

Effects of freezing and soil drought on the geochemical fractionation of americium in Fluvisol and Cambisol soils from Bulgaria [PDF]

, 2013
Extreme changes of environmental conditions can alter the soil properties and influence the migration ability and bioavailability of pollutants. Elucidation of the effects of the extreme weather conditions, such as sharp temperature change, drought and ...

Examining the Characteristics of Drought Resistance Under Different Types of Extreme Drought in Inner Mongolia Grassland, China

Remote Sensing
Extreme drought events may become more frequent with climate change. Understanding the impact of extreme drought on grassland ecosystems is therefore crucial for the long-term sustainability of ecosystems.

Drought risk probabilistic models based on extreme value theory

Environmental Science and Pollution Research, 2023
AbstractThe article presents original, probabilistic models for the quantification of drought risk, based on generalized distribution functions for the distribution of maximum values as well as the standardized precipitation index. Using the models, a probabilistic measurement of drought risk has been made for three regions over four 5-year periods for
