Summary: This study focused on the hydroclimate variability in the Jaguari River basin in southeastern Brazil, especially during historical meteorological droughts and the hydrologic response to negative rainfall disturbances. The results indicated that the recent serial meteorological droughts were unprecedented in the last 70 years, resulting in significant hydrologic impacts over a regional scale. The decrease in soil moisture and aquifer recharge, as well as the increased sensitivity in flow to precipitation, suggest a temporary loss of resilience in the surface hydrologic system.

Summary: Drought events and their impacts vary spatially and temporally due to diverse pedo-climatic and hydrologic conditions, as well as variations in exposure and vulnerability, such as demographics and response actions. Little is known about the effect of drought management strategies on the actual impacts and how the hazard is perceived by relevant stakeholders. This study characterised and assessed the impacts and perceptions of two recent drought events in Europe and examined the relationship between management strategies and drought perception, hazard, and impact.

Summary: This study evaluates the drought resistance and resilience of global vegetation productivity using long-term satellite observations, and finds a significant decline in drought resistance but no significant change in resilience. Temperature and soil moisture are identified as the main factors affecting drought resistance. Earth system models underestimate the historical drought resistance and resilience, and project further decline in the future.

Summary: Increased atmospheric demand for water leads to increased intensity of meteorological drought, which increases the risk of tree mortality and ecosystem dysfunction worldwide. However, the relationship between ecosystem water-use strategy and vulnerability to droughts is not well understood.

Summary: It is not widely accepted that water quality recovers to pre-drought levels after prolonged droughts, and there is still no clear answer to this question. By studying the changes in riverine salt load, it was found that the salt load decreases when the catchment shifts to a low runoff state. This suggests that reduced groundwater flow into rivers occurs as a result of the shift to a lower runoff state.

Summary: The study investigated the impact of drought and two cyclones exposure on three forms of self-reported IPV against women in India. Results showed a positive association between cyclone exposure and emotional IPV, and between drought exposure and physical IPV. Women from wealthier households, with higher education, and whose husbands had no history of alcohol consumption were less likely to experience any form of IPV.

Summary: Droughts are slow-onset disasters that can have devastating and long-lasting impacts. The poorest communities, particularly women, are the most vulnerable. This study in the Androy region of Madagascar aimed to understand the factors contributing to women's vulnerability to drought. The findings highlighted various factors, including climate, household size, duties, agricultural difficulties, early marriage, migration, and low education levels, that contribute to their high vulnerability. The study recommends that Antandroy women strengthen their adaptability by diversifying income-generating activities, using varied seeds, and protecting the environment.

Summary: This study investigates the growth resistance and resilience of forests in response to extreme droughts of different durations. The findings show that growth resistance and resilience are higher in humid regions compared to arid regions. The study also reveals that the impacts of climatic factors on growth resistance and resilience weaken as drought duration lengthens, with plant functional traits and soil properties becoming more important. Furthermore, the study highlights the need to improve the performance of Earth system models in accurately predicting growth resistance and resilience under drought conditions.

Summary: This study investigated the frequency and severity of droughts in the Upper Mzingwane sub-catchment using the SPI and RDI. The results showed that the sub-catchment was mainly affected by mild and moderate droughts, with a decreasing trend in long-term hydrological droughts. Both indices behaved similarly, but RDI was more sensitive to climatic conditions.

Summary: How climate change will affect the spatial coherence of droughts is an important question for water managers. Water transfers are crucial strategies to mitigate impacts on water resources, but these relationships may change in a warming world. This study analyzes the projected change in the spatial coherence of hydrological droughts in Great Britain, providing valuable insights for water managers to inform their long-term strategies.

Summary: This study compares the growth resilience of 20 conifer species to 11 dry years and finds that almost all species are resilient to drought in a mild maritime climate. Fast-growing species are more resilient, while hydraulic traits may be less important for growth resilience.

Summary: This study investigates the declining streamflows in the northern Murray-Darling Basin in Australia, and reveals the impacts of both meteorological and anthropogenic factors on the decrease in streamflow, resulting in the reduction of waterbird abundance and ecosystem resilience. The four-step framework developed in this study can be applied to any catchment with sufficient time-series data and helps in adapting to hydrological droughts.

Summary: This paper uses regression forests to model economic losses from earthquake disasters and finds that they can effectively improve prediction accuracy, with quantile regression forests performing the best. Earthquake magnitude is the main factor influencing economic losses. A new coverage of parametric insurance for earthquake catastrophes in Dali is obtained through quantile regression forests, significantly reducing the gap between the total economic loss and the insured loss.

Summary: Human activities both aggravate and alleviate streamflow drought, with water abstraction being the dominant aggravating factor and water transfers effectively reducing drought. Reservoir releases can alleviate drought in dry season but change flow seasonality. Land use has a smaller impact, with both positive and negative effects observed.

Summary: Forests' resistance and sensitivity to extreme climatic events are influenced by their ability to learn from past droughts. Factors such as geographical location, drought frequency, and previous droughts affect tree resistance and sensitivity to extreme drought events. This study helps us understand the vulnerability of high-elevation forest ecosystems on the Tibetan Plateau and is important for sustainable development under a changing climate.
