The availability and quantity of water is vital to life on earth and helps to tie together the Earth's lands, oceans and atmosphere into an integrated physical system. Our economic, political and social systems are being greatly affected by alterations in the global water cycle, particularly ...

(2020) disclosed a 50 % increase in population under water stress in a path of sustainability (SSP1) by the mid-21st century; such percentage might even double in a path of high population growth (SSP3). To assess the impact of climate change on a region’s water resources, it has ...

that within five years of planting trees, river flow had reduced by an average of 25%. By 25 years, rivers had gone down by an average of 40% and in a few cases had dried up entirely. The biggest percentage reductions in water availability were in regions in Australia and South Africa...
Three leading modes of coherent summer moisture variability are identified, and they have their largest loading over the northwestern United States, the southern plains, and the southwestern United States, respectively. No evidence is found for a statistically significant trend in the percentage area ...
Rainfall is that the primary sources of water for irrigation. Rainfall is not available throughout the year. The stored rain water either in tank or in sub-surface is employed as resources of irrigation water for crop periods mostly for Rabi Season (November鈥揂pril). So, it is needed to ...
This metric reflects the percentage of total instances that were correctly classified by the model, providing a straightforward measure of model performance. Despite data limitations, this unique approach allows us to scrutinize our model's outcomes.(2)Overall accuracy=Numbers of correct predictionTotal...
1). Overall, while this method yields a smaller percentage (~10% of global land area) of reduced seasonality regions (Supplementary Fig. 2), the spatial patterns of the recalculated seasonal changes of P–E are similar to those in Fig. 1, with spatial correlations of 0.94 and 0.98 for ...
The hydrological cycle is expected to intensify with global warming, which likely increases the intensity of extreme precipitation events and the risk of flooding. The changes, however, often differ from the theorized expectation of increases in water‐h
