Drought, being one of the most devastating natural disasters, has a far-reaching impact. In the context of global warming, it becomes crucial to quantitatively and scientifically assess the effects of anthropogenic climate change on meteorological drought in China. This assessment not only enhances our understanding of anthropogenic climate change...

Rising surface temperatures are projected to cause more frequent and intense droughts in the world's drylands. This can lead to land degradation, mobilization of soil particles, and an increase in dust aerosol emissions from arid and semi-arid regions. Dust aerosols are a key source of bio-essential nutrients, can be transported in the atmosphere o...
Global warming is considered one of the most significant causes of climate change. The increase in the frequency and severity of natural disasters such as floods, droughts, etc. in recent years is evaluated as a sign of climate change. In this context, the study conducted in Şanlıurfa province, which has a surface area of 19.242 km², aimed to deter...
With the acceleration of global warming, droughts are expected to both intensify and become more frequent. More so than forests, the productivity of grasslands is largely controlled by soil moisture and is highly susceptible to drought. Drought can impact grasslands though the effects may lag and accumulate over time. Because prior research has mai...
Water management is one of the crucial factors that impact the globally. As droughts become more frequent due to global warming, of this limited resource becomes increasingly important. Lately, tion of wastewater for irrigation purposes is considered a game that in many cases, wastewater treatment is poorly studied. This the EU member states water...
Drought is a complex phenomenon resulting from below-average rainfall and is characterized by frequency, duration, and severity, occurring at a regional scale with dire consequences, especially in semiarid environments. This study used the Reconnaissance Drought Index (RDI) to assess drought severity in two district municipalities in Limpopo Provin...

Climate change is altering the water cycle and increasing drought risks in river basins. However, few studies account for minor droughts, despite their limited environmental impact. This study uses a pooling and exclusion method to remove the effects of minor droughts on the identification of drought events and analyze drought characteristics in the Daqing River Basin (DRB) using the HADGEM3-RA model within an Exposure–Resilience–Vulnerability (ERV) framework. It finds that the drought duration and the number of events are sensitive to pooling and exclusion rates. Drought severity is also sensitive to exclusion rates. Pooling and exclusion lead to fewer but longer and more severe droughts. Future droughts in the DRB are projected to become more severe, with durations averaging up to 7 months and severity increasing from 0.2 to 4.3. Drought peak severity is expected to exceed 1.28, with development and relief periods extending to 0.68 and 0.69 months, respectively. Risk levels in the basin are projected to rise from I to II–IV, with RCP4.5 scenarios showing higher risks than RCP8.5. Mountainous areas will face higher risks compared to plains. Initially, risk factors will increase then decline over time. These findings clarify drought dynamics and risk changes in the DRB under climate change. They can help in developing climate-resilient strategies for disaster reduction in similar basins.
