Summary: The study reveals that the southern and coastal regions of Southeast Australia are most prone to drought, with a significant decrease in annual streamflow and an increasing trend in drought occurrences. EDI performs better than SPI at short timescales, and drought propagation time can be estimated using the 'theory of run', although it may not be directly applicable to other regions.

Summary: This study focused on analyzing meteorological drought using SPI and SPEI, as well as exploring hydrological drought with SSI. The research found that climate change has a significant impact on drought characteristics, with differences observed in drought characteristics across different climatic regions. Additionally, the study identified accurate relationships between drought duration and severity, with the highest accuracy observed in a 9-month period in the Navroud watershed basin.

Summary: The present study characterized drought in the Marathwada region of Maharashtra using meteorological, hydrological and agricultural drought indices. The study found that the 3-month SPI and 5-month VCI were the most appropriate time scales to observe meteorological and agricultural droughts, respectively, while none of the SDI's time scales could capture hydrological drought.

Summary: Drought and climate variation have significant impacts on human society and ecosystems in arid regions. This study uses spatiotemporal analysis to assess the linkage between different drought types and aims to establish an early warning system. The results show an increase in frequency of hydrological and meteorological droughts over the past three decades, and a strong correlation between the two.

Summary: Drought, a reversible climate phenomenon, is inevitable in arid and semiarid areas. Prediction of drought is vital to mitigate its effects, particularly hydrological drought which directly impacts water resources. The study in Iran analyzed rainfall and discharge data to establish a significant relationship between meteorological and hydrological droughts, with hydrological droughts occurring on average 7 months after meteorological droughts.

Summary: This paper examines the impact of drought on the Yazd province in Iran. The study uses the SPI and SWI indices to evaluate meteorological and hydrological drought, and employs machine learning algorithms to predict drought conditions. The results show an exacerbation of meteorological drought and a more severe hydrological drought in the region, primarily due to uncontrolled pumping wells.

Summary: In this study, the Cumulative Standardized Drought Index (CSDI) is developed to examine the impact of past dry or wet periods on the characteristics of drought events. The CSDI is used to determine meteorological and hydrological droughts in the Gordes and Tahtali watersheds in Izmir, Turkey, at different time scales. The results show that the CSDI method is effective in identifying the dry and wet periods and their characteristics in the watersheds.

Summary: Exploring the propagation from meteorological drought to hydrological drought and its potential influence factors is crucial for early warning of hydrological drought. A case study in the Xijiang River Basin (XRB), South China, was conducted using the Standardized Precipitation Index (SPI) and Standardized Runoff Index (SRI) series to represent meteorological and hydrological drought. The propagation regulations of drought variables, geographical location, and lag-time were established, and hydrological drought prediction from 2021 to 2050 was performed. The findings can help policy-makers manage the early stages of hydrological drought based on meteorological drought conditions and reduce the negative impact of drought hazards.

Summary: This study aims to investigate the relationships between meteorological and hydrological droughts in the Nakanbe River basin upstream Wayen hydrometric station (NRUW) in Burkina Faso. The results indicate distinct categories of droughts occurring at different time scales, and the relationships between the two types of droughts are crucial for effective monitoring and prediction of hydrological drought events.

Summary: Drought is a common climatic hazard that affects people's livelihoods and the economy worldwide. In order to accurately identify spatiotemporal variability and prevent negative impacts, a new procedure called STWJADI, based on the weighting scheme STTSSWS, has been developed in this study. It provides efficient and comprehensive information for drought characterization in the selected region.

Summary: This study investigated the impacts of climate change on future meteorological and hydrological droughts in the Mekong River Basin and its surrounding areas. The results suggest that droughts will generally reduce in the future over most of the study area, but will be more unevenly distributed with an eastward migration. Both meteorological and hydrological droughts will intensify in the near future, but will then reduce in intensity.

Summary: Electric cars are becoming more popular in Poland and around the world. However, due to the majority of energy coming from non-environmentally friendly fossil fuels, the green credentials of electric cars are being questioned. The solution to this problem lies in increased investment in renewable energy sources, particularly hydroelectric power.

Summary: The COVID-19 pandemic has had both positive and negative impacts on water bodies. On the positive side, monitoring SARS-CoV-2 in sewage water has proven to be useful in quickly identifying community infections, and pollution levels in many water bodies around the world have decreased during the pandemic. On the negative side, the presence of SARS-CoV-2 in untreated sewage water amplifies the health risk, there is a lack of proper elimination processes for plastics, drugs, and biological pollution in wastewater treatment plants, an increase in municipal and medical waste pollution in water bodies, and a decrease in waste recycling.

Summary: This study aims to investigate the patterns and trends of drought occurrence in the northern part of Poland based on the Leba river basin data from 1956 to 2015. The Standardized Precipitation Index (SPI) was used to analyze meteorological drought on different time scales. The results showed that annual precipitation did not change significantly except for a station in Wejherowo with an increasing trend. The average annual air temperature had a statistically significant increase, and a total of 14 to 84 droughts were identified during the analyzed period. Most droughts were mild, but extreme droughts accounted for a small percentage of the duration. Drought intensification was observed in February and March for SPI-1 in Wierzchucino, while a decreasing trend was noted for longer accumulation periods (SPI-6, 9, and 12).
