Droughts have been exacerbated by climate change, posing significant risks to ecosystems, hydrology, agriculture, and human society. In this paper, we present the development evaluation of a high-resolution 1 km SPEI (Standardized Precipitation-Evapotranspiration Index) dataset enhance drought monitoring at finer spatial scales. The datasets, derived using TPDC precipitation satellite-based MODIS potential evapotranspiration data, were compared with coarse-resolution 50 from CRU measurements, as well vegetation health indices (VHIs) root zone soil moisture (SM), over two climatically contrasting regions in China: Northeast China (NEC) Southwest (SWC). highlights MODIS-based SPEI’s ability capture regional dynamics improved correlation dynamics. NEC, its relatively flat topography recent experience droughts, SWC, characterized complex terrain high variability, provided ideal testbeds for examining performance SPEI. results demonstrate that offered superior detail detecting conditions, making it valuable agricultural planning water resource management diverse climates.

Under the dual pressures of climate change and rapid urbanization, a comprehensive analysis vegetation’s spatiotemporal patterns their driving forces plays pivotal role for addressing global ecological challenges. However, systematic bibliometric analyses in this field remain limited. This study involved 18,270 related publications from 1989 to 2024 retrieved Web Science SCI-Expanded database, elucidating research trends, methodologies, key thematic areas. Utilizing bibliometrix biblioshiny tools, results reveal an annual average growth rate 17.62% number published articles, indicating expansion. Climate emerged as core force, with high-frequency keywords such “vegetation”, “dynamics”, “variability”. China (18,687 papers), United States (14,502 Germany (3394 papers) are leading contributors domain, showing fastest output, albeit relatively lower citation rates. Core journals, including Remote Sensing Environment Global Change Biology, have played roles advancing vegetation dynamics research, remote sensing techniques dominating field. The highlights shift single-variable (e.g., temperature, precipitation) multi-scale multidimensional approaches around 2010. Regional studies, those focusing on Loess Plateau, gaining importance, while advancements machine learning technologies enhanced precision scalability research. provides summary current state development trends forces, offering valuable insights future

Abstract This study projects near-future (2031–2050) changes in heatwave (HW) risk across West Africa (WA) using an ensemble of eight high-resolution global climate models from the High-Resolution Model Intercomparison Project under a high-emission scenario. Using K-means clustering, we divided WA into four unique temperature zones and examined projected extreme temperatures, HW occurrence magnitude. Our results indicate statistically significant increase future events most parts WA, although considerable spread exists over region among individual models. The pronounced increases are evident Sahel/Sahara Guinea Highlands subregions, with mean ∼10 per year. In contrast, lowest is central ranging between 1 5 Similarly, magnitude to models, exhibiting largest increases. Additionally, projections suggest that strongest HWs will become more frequent, particularly northern southwestern WA. These findings highlight spatial heterogeneity emphasizing need for targeted adaptation strategies.

Under the 1960 Indus Water Treaty, Pakistan owned Western rivers (Indus, Jhelum, and Chenab) India Eastern (Ravi, Suleimanki, Beas). Pakistan’s per capita water availability will reduce from 5260 m3 to less than 1000 by 2025, causing stress. The Basin’s was examined at inflow outflow gauges between 1991 2015. Basin indicated exceptionally low high flows before, during, after floods. Lower flow values vary greatly for Indus, Chenab, Jhelum rivers. During Rabi Kharif, Chenab behaved differently. (Q90 Q99) in Rivers are more periodic higher medium Q99). gauge Kotri reported 35% exceedance with zero during pre-flood post-flood seasons 50% flood season, indicating seasonal concerns. Outflow both fell, particularly year 2000, according data collected over a longer period (1976–2015). Low storage regulating upstream capacity caused reach 28 MAF (million acre feet) 1976 2015, which is 70% permitted 8.6 downstream gauge. For 65 percent of year, does not release any Kotri. As result, ecosystem relies on an annual influx least 123 sustain itself, necessitates 113.51 MAF. At high-flow seasons, experiences devastating floods, yet it dries out frightening rate before preservation ecosystems riparian zones depends large environmental eastern This achievable only fully implementing IWT improving management practices western
