Exploring Afro-Asian water fluxes in CMIP5 and CMIP6 models: Present-day evaluation and future projections

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 977, P. 179374 - 179374

Published: April 15, 2025

Accurate representation and projection of water fluxes are vital, particularly in monsoon regions where seasonal variability changes significantly impact resources, agriculture, hydroelectric power generation, the economy. This study uses both CMIP5 CMIP6 models to investigate present-day key flux components (including precipitation, evaporation, vapor, moisture advection) over Afro-Asian region during summer (JJAS). We also examine future under two emission scenarios assess underlying physical mechanisms driving these while identifying sources uncertainty. Our results show that reasonably capture characteristics components, although with noticeable biases. Across most regions, we find demonstrate slight improvements components. In a warmer future, robust intensification JJAS precipitation (exceeding 0.25 mm/day) is projected across region. increase largely driven by vertical thermodynamic term associated increasing temperature. model uncertainty primary source projections, accounting for 50 % total variance.

Climate change is intensifying rainfall erosivity and soil erosion in West Africa

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 955, P. 177174 - 177174

Published: Nov. 2, 2024

Soil erosion is a critical environmental challenge with significant implications for agriculture, water quality, and ecosystem stability. Understanding its dynamics essential sustainable management societal welfare. Here, we analyze rainfall erosivity patterns across West Africa (WAF) during the historical (1982-2014), near future (2028-2060), far (2068-2100) periods under Shared Socioeconomic Pathways (SSPs 370 585). Using bias-corrected-downscaled (BCD) climate models validated against reference data, ensure an accurate representation of rainfall-a key driver (R-factor) soil erosion. We compare Renard's approach Modified Fournier Index (MFI) to calculate R-factor note strong correlation. However, method shows slightly lower accuracy in Sierra Leone, Guinea, The Gambia, likely due inability capture high-intensity, short-duration events. In contrast, MFI, utilizing continuous rain gauge proves more reliable these regions. also attribute fluctuations erosivity, such as those seen 2003 floods, synoptic weather influenced by multiple processes. Furthermore, our analysis reveals regions where could exceed 20 t/ha/yr change. Under SSP scenario, WAF projected rise 14.84 % 18.65 future, increasing further 585 19.86 23.49 %, respectively. most severe increases are expected Benin Nigeria, Nigeria potentially facing 66.41 585. These findings highlight region's exposure intensified climatic conditions underscore urgent need targeted adaptation strategies mitigate erosion's ecological socioeconomic impacts.

Global warming is one of the most pressing challenges our time, contributing to climate change effects and with far-reaching implications for built environments. The main aim this study assess extent which Annaba city, Algeria, as part Mediterranean region, affected by global its broader influences. investigated climatic shifts in using a multi-step methodology integrating data collection analysis techniques. Data included 23 years (2000–2023) from Annaba’s meteorological station, on-site measurements microclimatic variations, questionnaire survey. collected underwent four analyses: time series describe parameters over years, statistical predict potential future conditions (2024–2029) correlation various variables specialized bioclimate tools highlight seasonal variability, spatial urban heat island (UHI) phenomenon perceived shifts, an extreme weather events characterizing atmospheric context region. findings revealed consistent trend prolonged observed, particularly last (2020–2023). Significant temperature fluctuations were emphasized, notably July 2023, record-breaking maximum temperatures reaching 48.2 °C, hottest on record increase 3.8 presenting amplified effect, causing differentials up 6 °C within built-up areas.

A distributed modeling approach to water balance implications from changing land cover dynamics in permafrost environments

Geography and sustainability, Journal Year: 2024, Volume and Issue: 5(4), P. 561 - 576

Published: July 5, 2024

There is 78% permafrost and seasonal frozen soil in the Yangtze River's Source Region (SRYR), which situated middle of Qinghai-Xizang Plateau. Three distinct scenarios were developed Soil Water Assessment Tool (SWAT) to model effects land cover change (LCC) on various water balance components. Discharge percolation groundwater have decreased by mid-December. This demonstrates contributions subsurface water, diminish when freezes. During winter, surface inputs are low, storage becomes even more critical ensure supply due this periodic trend. An impermeable layer underneath active thickness decreases GWQ PERC LCC + scenario. The transport phase reached a point August precipitation, thawing, snowmelt caused LATQ surge. To prevent waterlogging save for dry periods, it necessary control peak flow phase. Hydrological processes, dynamics, changes SRYR difficult, according data. These interactions enhance circulation throughout year, recharge supplies, runoff, lateral flow. For region's resource management be effective sustaining ecohydrology, ensuring appropriate storage, alleviating freshwater scarcity, these dynamics must considered.
