Water supply for drinking and agricultural purposes in semi-arid regions is confronted with severe drought risks, which impact socioeconomic development. However, early forecasting of indices crucial water resource management to implement mitigation measures against its consequences. In this study, we attempt develop an integrated approach forecast the hydrological a zone ensure sustainable agr...

Drought monitoring is a complicated issue as it requires multiple meteorological variables to monitor and anticipate drought accurately. Therefore, developing method that enables researchers, data scientists, planners comprehend mitigation policies more accurately essential. In this research, based on the concepts behind calculation of Standardized Precipitation Evapotranspiration Index (SPEI),...

Drought is an event of shortages in the water supply, whether atmospheric, surface or ground water. Prolonged droughts have negative impacts on ecosystems, agriculture, society, and economy. Although existing drought index products are widely utilized monitoring, coarse spatial resolution greatly limits their applications regional local scales. Machine learning driven by remote sensing observat...

Global warming is likely to cause a progressive drought increase in some regions, but how population and natural resources will be affected still underexplored. This study focuses on global population, forests, croplands pastures exposure meteorological hazard the 21st century, expressed as frequency severity of events. As input, we use large ensemble climate simulations from Coordinated Region...

The climate anomaly in the Amazon River basin (ARB) has a very important influence on global change and always been focus of scientists from all over world. To fill 11-month data gap between Gravity Recovery Climate Experiment (GRACE) GRACE Follow-On (GRACE-FO) missions, we fused TWSC results six solutions by using generalized three-cornered hat least square method to improve reliability result...

Drought is an inevitable condition with negative impacts in the agricultural and climatic sectors, especially developing countries. This study attempts to examine spatial temporal characteristics of drought its trends Koshi River Basin (KRB) Nepal, using standardized precipitation evapotranspiration index (SPEI) over period from 1987 2017. The Mann-Kendall test was used explore SPEI values. ill...

Current methods for climate change assessment ignore the significant differences in uncertainty model projections of two key constituents drought, precipitation, and evapotranspiration. We present here a new basis assessing future drought using simulations that addresses this limitation. The method estimates Standardized Precipitation Evapotranspiration Index (SPEI) two-stage process. first sta...
