In this study, the temporal and spatial variations of groundwater drought using a Standardized Groundwater Level Index (SGI) were analyzed based on 40 monthly groundwater level observation wells from 1989 to 2012 in Jiangsu Province, China. Meteorological drought, calculated by the Standardized Precipitation Index (SPI), was also included to reveal its propagation and impact on the groundwater ...

Australia's previous government was one of the most 'climate change sceptic' of any nations. The new government has 'greener' credentials, but it has already been hit with alarming projections. The country, which has been hit by increasing droughts in recent years, could be facing much worse. A new report by Australia's leading scientists predicts that the country may be hit by a tenfold increa...

Abstract. Climate change is projected to increase the imbalance between supply (precipitation) and atmospheric demand for water (i.e., increased potential evapotranspiration), stressing plants in water-limited environments. Plants may be able offset increasing aridity because rising CO2 increases use efficiency. fertilization has also been cited as one of drivers widespread “greening” phenomeno...

The African savanna biome supports a higher diversity of ungulate species than is found in any other biome or continent. This exceptional faunal diversity and herbivore biomass density is directly linked to the high spatial heterogeneity of African savanna ecosystems. The dependence of herbivore dietary tolerance on body size translates into important size-related differences between savanna un...

groundwater drought is a natural hazard that develops when groundwater systems are affected by climatical drought, when climatical drought occures, first groundwater recharge, later groundwater levels and groundwater discharge decrease. the origin of drought is a deficit in precipitation and that takes place in all the elements that comprise the hydrological cycle (flow in the rivers, soil mois...
