“…These changes have contributed to the changes in the spatial distribution and trends in concurrent droughts and hot extremes in northwest China. precipitation but also because of increasing evaporation driven by global warming (Dai, 2011;Trenberth, 2011;Sheffield et al, 2012;Greve et al, 2018;Samaniego et al, 2018). The relationship between droughts and hot extremes is widely acknowledged (Vautard et al, 2007;Zampieri et al, 2009;Mueller and Seneviratne, 2012).…”

Northwest China forms the main part of the arid and semiarid areas in China, and even includes some extremely arid areas. This zone of interaction is affected by the westerlies and monsoons making it sensitive to global climate change. Drought is the main type of natural disaster affecting northwest China. Global warming has caused a gradual strengthening of the frequency and intensity of hot extremes, when dry conditions and heatwaves occur simultaneously or successively; as a result, that socioeconomic risks can increase considerably. The present study examined changes in concurrent droughts and hot extremes in northwest China during 1961–2017 based on data from 119 meteorological stations. The result shows that the frequency of concurrent droughts and hot extremes exhibited an increasing trend over most parts of northwest China, while a negative trend occurred in western Xinjiang and at some sites in Qinghai. Concurrent droughts and hot extremes appeared more often in May in western Xinjiang, and in summer in other parts of northwest China. Overall, the trends of such concurrent events, regardless of different definitions, increased from 1961–2017 over northwest China. In particular, from 1981–2017, the trend rose more significantly than in other decades, and reached an abrupt point of change in 1996. Although the trend changed from a positive significant signal to a negative one from 2001–2017, the trend grew 2–3 times from 1997–2017. Changes in large‐scale atmospheric circulation show that an anticyclonic circulation strengthened, increasing in geopotential height over the midhigh latitudes of Eurasia and was centred on Mongolia and Lake Baikal. This enhanced relative humidity in western Xinjiang and eastern Qinghai, and weakened it elsewhere from 1997–2017. These changes have contributed to the changes in the spatial distribution and trends in concurrent droughts and hot extremes in northwest China.

“…This linked trends in global drought patterns to human activities, revealing that anthropogenic actions could continue to influence droughts in the context of climate change (Marvel et al, 2019;Samaniego et al, 2018). For instance, Samaniego et al, 2018 revealed that anthropogenic warming is exacerbating soil moisture droughts in Europe. Anthropogenic climate change has altered the European river and streamflow discharges, suggesting increased water scarcity in renewable freshwater resources (Gudmundsson, Seneviratne, & Zhang, 2017).…”

“…To accommodate the influences of anthropogenic activities during the Anthropocene, different methods have been used to analyze droughts. The use of historical meteorological datasets, such as rain and temperature measurements as well as satellite-based soil moisture datasets, have been increasingly applied recently (Marvel et al, 2019;Samaniego et al, 2018). Similarly, tree rings, sediments and rocks, vapor pressure deficit data, remotely sensed vegetation greenness, and higher resolution models are the main methods used to analyze/predict droughts (Anderegg et al, 2015;Mishra & Singh, 2010;Stocker et al, 2018Stocker et al, , 2019Xiao et al, 2009).…”

Drought affects many aspects of society and its impact is global. To this end, rendering recurrent drought occurrences is a key research focus. Recently, in addition to existing knowledge, progress in scientific advancements regarding drought have been observed on a regional and global scale. Here, we reviewed and outlined current and emerging scientific developments in drought, focusing on progress made in recent years. In the human‐modified world, the anthropogenic effects on drought were dominant and drought‐frequency showed a prominent increase. In this study, we have identified the development of drought concepts, types, and indices, and their indicators were developed as sector‐specific, comprehensive, and oriented towards multiple scales. Anthropogenic changes have enhanced hydrological processes and affected the development of drought. Urbanization, deforestation, and related human activities have aggravated drought. Climate change has had an exacerbating role in drought, which is expected to increase during the 21st century. Human communities, in particular, are undertaking activities that cause droughts; suffering from and coping with their impact. In addition, the direct and indirect effects of drought need reconsideration. As such, the health impact of droughts is a concern in drought‐vulnerable societies and its burden on public health is largely unknown. The need for drought recovery to aid in effective ecosystem functioning in the aftermath of the drought and the development of mitigation measures to alleviate recurrent drought is critical. Enhanced drought monitoring and management options are required under existing environmental and socio‐economic setups in the 21st century.

“…Besides the technical provisions to maintain water of good quality, the uninterrupted availability of water becomes an issue due to climate change manifestations, especially in areas that are now or expected to be hit harder by extended droughts and other related meteorological phenomena. Europe, overall, is expected to face increases in both the extent of geographical areas affected by droughts and in the duration of such climatic events (11).…”

Cities face rapid changes leading to increasing inequalities and emerging public health issues that require cost-effective interventions. The urban exposome framework constitutes a novel approach in tackling city-wide challenges, such as those of drinking water quality and quality of life. In this proof-of-concept study, we presented part of the urban exposome of Limassol (Cyprus) focusing on chemical and microbial drinking water quality parameters and their association with urban neighborhood indicators. A perceptions study and an urban population study was conducted. We mapped the water quality parameters and participants’ opinions on city life (i.e. neighborhood life, health care and green space access) using quarters (small administrative areas) as the reference unit of the city. In an exploratory environment-wide association study analysis, we used all variables (questionnaire responses and water quality metrics) to describe correlations between them accounting, also, for self-reported health status. Overall, urban drinking-water quality using conventional indicators of chemical (disinfection byproducts-trihalomethanes) and microbial (coliforms, E. coli, and Enterococci) quality did not raise particular concerns. The general health and chronic health status of the urban participants were significantly (all >FDR corrected p value of 0.1) associated with different health conditions such as hypertension and asthma, or having financial issues in access to dental care. Additionally, correlations between trihalomethanes and participant characteristics (e.g. household cleaning, drinking water habits) were documented. This proof-of-concept study showed the potential of using integrative approaches to develop urban exposomic profiles and identifying within-city differentiated environmental and health indicators. The characterization of the urban exposome of Limassol will be expanded via the inclusion of biomonitoring tools and untargeted metabolomics platforms.
