“…Maps are available showing single parameters such as annual temperatures or rainfall but can also show more complex phenomena such as winddriven rain (Blocken and Carmeliet 2004). Different disciplines use climate-based maps to explain and categorise regions, for instance, with respect to climate (Beck et al 2018;Köppen 1884), wind and snow loads (European Committee for Standardization 2003), vegetation (Defaut 1996;Küchler and Zonneveld 2012), or flood and drought risk (Kourgialas 2020). Well established climate classification systems such as the Köppen-Geiger (Beck et al 2018;Köppen 1884) system can provide the first indication of decay risks since the material climate of wood is affected by the macroclimate.…”

Mapping the biotic degradation hazard of wood in Europe – biophysical background, engineering applications, and climate change-induced prospects

Construction using timber has seen a resurgence in light of global climate mitigation policies. Wood is a renewable resource, and engineered wood products are proving to be competitive against concrete and steel while having several advantages. However, while the renewable nature of wood in construction is a beneficial property for climate mitigation policies, the process of biodegradation introduces a challenge for service life planning. A review of hazard mapping is presented while developing contemporary hazard maps, occurrence maps and projected hazard maps for 2050 using representative concentration pathways (RCP) 2.6 and 8.5. The risk of timber decay is expected to increase in most of Europe as the temperatures rise, with a decrease expected in dryer regions. Termites are likely to experience a range expansion as more areas become suitable, while human activity and an increase in extreme weather events like floods are expected to facilitate dispersion. Marine borer species already present a risk in most European coastal regions; however, the effect of changes in water temperatures are likely to shift the boundaries for individual borer species. Overall, warmer climates are expected to increase the metabolic activity of all of these organisms leading to a general reduction in service life.

“…Some scholars have assessed the impact of global change on flood and drought risk in Europe and proposed that the frequency of floods has increased in northern and northeastern Europe, while the frequency of droughts has increased significantly in southern and south-eastern Europe [1,2]. Kourgialas et al [3] assessed the impact of climate change on drought or flood in the region based on the standardized precipitation index (SPI) in northwestern Crete in Greece from 1960 to 2019, pointing out that there have been frequent droughts and floods in the region in recent decades. The authors also predicted that drought would become more frequent in the coming decades.…”

Droughts and floods have proven to be threats to food security worldwide. This research used the standardized precipitation index (SPI) to examine the spatiotemporal characteristics of drought and wet events from 1961 to 2020 in the Yellow River basin (YRB). Grain yield data were combined to assess how drought and wet frequency have affected the agricultural system. The occurrence frequency of drought was greater than that of wetness in time, drought frequency decreased, and wetness increased. Spatially, the frequency of drought in all provinces except Shanxi was higher than that of wetness. The grain yield per unit area of the YRB was generally highest in Shandong province and lowest in Gansu province. The grain yield per unit area have shown a significant growth trend in the nine provinces of the YRB since 1961. Drought had a negative effect on the grain yield per unit area in each province, while wetness had a positive effect on the grain yield per unit area in all provinces except Shandong. In general, the influence of drought on grain yield per unit area decreased, while the influence of wetness on grain yield per unit area increased. The results indicate that human activities are effective against preventing and controlling drought and wet disasters and can provide a reference for other parts of the world.

“…Ashraf (2013) and Ashraf and Routray (2015) conducted research on hydrological changes resulting from alterations in land cover using the SWAT model for the contiguous Rawal watershed, which serves as a subwatershed within the larger Soan watershed. Due to its significant threat to both the ecosystem and society, numerous studies have endeavored to examine the spatial-temporal attributes of hydrological droughts (Chen et al, 2020;Kourgialas, 2021;Zhang & Jin, 2021). Various indicators were employed to identify hydrological droughts, including measures such as discharge quantile (e.g., Q95), standardized water-level index, surface water supply index, aggregate dryness index, and standardized runoff index (Gonçalves et al, 2023;Wang et al, 2022;Waseem et al, 2015;Zhang et al, 2017).…”

Climate change and rapid socioeconomic development have exacerbated the damage caused by hydrological droughts. To ensure effective drought defense and infrastructure development, it is essential to investigate variations in hydrological droughts. The primary objective of this study is to reconstruct the natural streamflow by using Soil and Water Assessment Tool (SWAT) hydrological modeling. The hydrological drought at different time scales (1, 3, 6, and 12 months) were measured using the streamflow drought index (SDI). The statistical parameters, including Nash–Sutcliffe Efficiency and the Coefficient of Determination, which yielded values of 0.84 and 0.82 during the calibration period and 0.78 and 0.76 during the validation period, respectively, showed a satisfactory SWAT model performance. Additionally, the Pettit test was used to identify a change point in streamflow within the 1991–2015 timeframe, leading to the division of the study period into two distinct phases: an undisturbed period (1991–1998) and a disturbed period (1999–2015). The SDI index‐based analysis revealed 9.39% moderate drought and 3.13% severe drought during the undisturbed period, while 11.76% moderate drought and 7.35% severe drought may happen due to the human influences that occurred in the disturbed period. These findings enhance the understanding of the hydrological drought variations in the Soan River basin for optimizing the water resources management system and effectively preventing and mitigating drought‐related damages.
