Soil moisture-drought linkages in the Brahmaputra Valley: a multi-index approach to understanding increasing droughts in recent decades

Development of drought index and quantitative assessment of spatiotemporal distribution characteristics of the Loess Plateau using multi-source remote sensing

Drought significantly affects water and carbon cycles of the terrestrial ecosystems, particularly in arid and semi-arid regions. However, drought monitoring using remote sensing approaches remains limited, because remote sensing-based drought indices lack explicit physical mechanisms. To address this gap, this study de...

Assessing the influence of drought index selection on drought characteristics: insights from precipitation-based indices in the Wadi Sly Basin, Algeria

Multiple indices based agricultural drought assessment in Guba Lafto and its surrounding, northeast Ethiopia

Development of the Potential Evapotranspiration-Vegetation-Precipitation Drought Index (PETVPDI) and Its Application in West Africa Using Remote Sensing Datasets

Drought remains one of the most severe climate-related hazards affecting water resources, ecosystems, and agricultural productivity in West Africa (WA). Traditional drought indices often rely on individual hydroclimatic or vegetation variables and may not fully represent the coupled effects of precipitation supply, atm...

Multi-scale drought monitoring using meteorological and vegetation indices over different agro-climatic zones of Tamil Nadu, India

Drought episodes pose severe dangers to agricultural productivity and disrupt global socio-economic situations. Climate change and global warming are predicted to intensify drought risks and their impacts on natural resources and agricultural systems. A study was conducted at the Agro-Climate Research Centre, Tamil Nad...

Comparative Assessment of Palmer Drought Indices for Hydrological and Agricultural Drought in the Mediterranean Ceyhan Basin, Türkiye

Hydrological drought is an increasing challenge for water security, ecosystem resilience, and water resource management in Mediterranean river basins, emphasizing the need for reliable indicators capable of capturing regional hydroclimatic variability. This study evaluates the effectiveness of the Palmer Hydrological D...
