Abstract As the upward trend in extreme drought continues with climate change, terrestrial vegetation growth is assumed to become largely reduced. We investigated anomalies of remote sensing indexes under droughts across upper Yangtze River (UYR) basin, characterized as humid but having experienced frequent seasonal from 2000. Then we compared global big river basins by focusing on Nile and Congo basins, which have similar characteristics UYR. The UYR was affected water stress recent years shows reduced sensitivity drought. compound effect timing phenology drives response. Results show that late‐season generally a greater impact early season droughts, alpine grasslands showing particularly pronounced responses due their ecological features such shallow root depth aggressive hydrological behavior. exhibits vulnerability, highlighting shared patterns heterogeneous landscapes. In contrast, tropical rainforests basin demonstrate resilience, supported complex systems, dense canopies, low cloud cover reduces evaporation. This study underscores importance considering regional characteristics, timing, phenological stages assessing These insights are critical for predicting managing ecosystem resilience changing climatic conditions.

Drought is one of the most frequent types natural disasters in world, and it has been classified into several different categories. Generally, meteorological drought considered to be beginning a disaster, while socio-economic possible ultimate result.

Abstract Droughts, depending on their nature, have had devastating consequences, including crop destruction, famine and millions of deaths, particularly in countries like India that heavily rely rainfall for agriculture. The present study aims to quantify the linkage between meteorological, agricultural hydrological drought at a high spatial resolution across India. These connections were established by developing various propagation metrics followed subsequent correlation analysis, lag analysis clustering. Standard Precipitation Index (SPI), Deviation NDVI (Dev‐NDVI) GRACE Drought Severity (GRACE‐DSI) used represent droughts. Run theory with thresholds −1, −0.5 −0.05 delineate events droughts, respectively. Furthermore, multivariate K‐means clustering based factors such as duration, latitude, longitude, severity, recovery speeds was done create clusters having similar characteristics. Correlation showed highest average correlations around 7–8 months meteorological drought, 1–2 case 3–4 drought. duration indicated that, average, lasted 2.34 months, while 3 reflecting 26.5% increase, whereas 5.22 indicating notable 123% increase. This increase it propagates from can be attributed lengthening property propagation. Clustering reveals presence five homogeneous clusters. Additionally, cluster droughts arid regions severity north Indian states Punjab Haryana severity.
