Drought is a complex phenomenon which can be characterised mainly by its severity, duration and areal extent. Among these three dimensions, drought severity is the key factor which can be used for drought analysis. Drought indices are typically used to assess drought severity in a meaningful way. DrinC (Drought Indices Calculator) is a software package which was developed for providing a simple...

Drought stress caused by unpredictable precipitation poses a major threat to food production worldwide, and its impact is only expected to increase with the further onset of climate change. Understanding the effect of drought stress on crops and plants' response is critical for developing improved varieties with stable high yield to fill a growing food gap from an increasing population dependin...

Drought is one of the most damaging environmental phenomena. In general, drought is a temporal reduction of environmental moisture status relative to the mean state. Because of the complexity of drought, it is often studied only by separate aspects of the phenomenon (e.g. meteorological drought, soil drought, etc.). Hence, approaches to drought identification are variable. The theory of drought...

Drought is a major environmental factor that limits crop growth and productivity. Flue-cured tobacco (Nicotiana tabacum) is one of the most important commercial crops worldwide and its productivity is vulnerable to drought. However, comparative analyses of physiological, biochemical and gene expression changes in flue-cured tobacco varieties differing in drought tolerance under long-term drough...

In the anoxic Cariaco Basin of the southern Caribbean, the bulk titanium content of undisturbed sediment reflects variations in riverine input and the hydrological cycle over northern tropical South America. A seasonally resolved record of titanium shows that the collapse of Maya civilization in the Terminal Classic Period occurred during an extended regional dry period, punctuated by more inte...

Recurrent occurrence of drought stress in varying intensity has become a common phenomenon the present era global climate change, which not only causes severe yield losses but also challenges cultivation rice. This raises serious concerns for sustainable food production and security. The root plant is primarily responsible to perceive acquire sufficient water survival/optimal growth under extre...

Drought is one of the most threatened natural vulnerabilities that are initiated by reason of scarcity of rain in a specific region. By comparing with all other natural hazards, it is very tough to discover since it develops slowly and have massive effect on the society and environment. Hence, in many countries satellite based drought indications have been recommended for early identification. ...
