With the intensification of climate change, the frequency and severity of drought events are expected to rise, amplifying their detrimental effects. This study addresses hydrological drought in the Eastern Black Sea Basin (EBSB) in Turkey, a region characterized by high precipitation but largely understudied in terms of drought vulnerability. The Standardized Streamflow Index (SSFI) is employed to assess the drought characteristics across six different hydrological stations in the basin between 1965 and 2011. The sensitivity of the SSFI to the selected probability distribution functions (PDF) was assessed, with Generalized Logistic distribution identified as the most suitable model for the EBSB. The results reveal not only basin-wide drought events but also significant spatial variability in drought severity, particularly during the droughts of 1969–1971, 1994, and 2001. This highlights the region's susceptibility to severe droughts, despite its overall wet climate. The findings underscore the necessity of implementing integrated drought monitoring systems and developing proactive water resource management strategies to mitigate future risks. This study offers new insights into hydrological drought in the EBSB, providing a foundation for future research on drought monitoring and adaptation strategies in similar climates.</div></div>","PeriodicalId":54616,"journal":{"name":"Physics and Chemistry of the Earth","volume":"139 ","pages":"Article 103946"},"PeriodicalIF":3.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143828855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the essential role of rocks in the construction of various structures, it is imperative to prioritize the analysis of these geological formations. Therefore, it is imperative to thoroughly examine all potential future scenarios in which adverse environmental conditions manifest.

The inherent strength and failure behavior of rocks are modified by physico-mechanical changes induced by elevated temperatures. The development of appropriate remediation and renovation protocols for structures damaged by fire can be achieved by quantifying the thermally-induced alterations.

The multifaceted impacts of climate change on resources with a particular reference to the water, energy and food (WEF) nexus in the MENA countries are critically reviewed. Increasing population pressure (estimated 724 million by 2050) leads to higher demands on energy, especially electricity (an increase of 416 % from 1990 to 2022.), reaching 1060 TWh in 2020 due to urbanization and industry activities. This contributes to climate change, leading to higher regional temperatures in in Gulf Cooperation Council (GCC) countries and Iran, which has risen by 1.2 °C since 1970. It is estimated that by 2050, temperature increases in MENA countries range from 1.5 to 3 °C. This in turn exacerbates drought, causing severe heatwaves and water scarcity, particularly in Egypt, Yemen, Syria and Sudan, affecting food production and security. The nexus concept highlights the interconnected challenges of water, energy and food in the MENA region amid climate change, where alterations in one element reverberate through the others. Adapting to this dynamic scenario involves solutions such as water desalination, where energy generated by renewable sources such as solar and wind as well as hybrid systems combining solar and fossil fuels offers a versatile solution; i.e., solar energy is utilized during the day, while fossil fuels provide backup power during periods of low sunlight or high demand.</div></div>","PeriodicalId":54616,"journal":{"name":"Physics and Chemistry of the Earth","volume":"139 ","pages":"Article 103936"},"PeriodicalIF":3.0,"publicationDate":"2025-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among these, social integration risk, social network risk, rural social contact risk, and family relationship risk emerged as the most significant contributors to the overall risk profile. Risk assessments show consistent results, regardless of whether individual characteristics were controlled, highlighting the widespread nature of these challenges. A central risk scenario is the “urbanization dilemma,' where migrant workers face barriers to full urban integration while losing rural ties. This dilemma is driven by government policies, enterprise practices, and individual circumstances, leading to potential outcomes such as social disharmony, labor-capital conflicts, and risks of land loss and unemployment. To address these risks, a dual strategy of pre-prevention and post-control is proposed. Pre-prevention measures include promoting social integration, reforming land policies, and strengthening community support systems.
