Abstract Background High-resolution local scale climate research approach is very effective in examining the existing change and predicting its risk. Thus, this study investigated hydroclimate distribution, variation, trend, abrupt points, considered more than normal time range (1981 to 2020) determine of Dabus River Basin. The employed different statistical, parametric, nonparametric modified trend tests, exact changing point detecting models. Results result found basin received 57.7% annual rainfall June, July, August. standard anomaly index (SAI) value indicates 1999 2000 were wettest years whereas 1982,1983,1984,1986 2015 driest area. experienced fluctuating for last four decades. Peaks Precipitation Concentration Index (PCI) observed 1987,1991, 2002,2003,2006, 2011 which strong irregular distribution rainfall. mean maximum temperature (Tmax) increased significantly (p < 0.05), minimum (Tmin), river flow, runoff decreased. In increasing was 1996 Tmax 1993 1997. decreasing Tmin, 1987, 1998, 1999, respectively. Conclusions due significant increase with as well reduction flow runoff. This could upset agriculture, electric power production, water demand basin.

Farmers in Ethiopia have been vulnerable to climate change recent decades. In the face of this change, farmers managed agroforestry systems maintain their livelihoods. However, studies exploring role reducing household vulnerability are lacking Northwestern Ethiopia. The objectives study were (i) investigate households' livelihoods Ethiopia; (iii) assess mitigating negative impacts on Key informant interviews, in-depth surveys (387), and focus group discussions used collect data.

Agricultural productivity is significantly influenced by climate-related factors. Understanding the impacts of climate change on agroclimatic conditions critical for ensuring sustainable agricultural practices. This study investigates how key variables—temperature, moisture conditions, and length growing season (LGS)—influence wheat suitability in Upper Blue Nile Basin (UBNB), Ethiopia. The Global Agroecological Zones (GAEZ) methodology was employed to assess suitability, integrating projections from Climate Models Intercomparison Project v6 (CMIP6) under shared socioeconomic pathway (ssp370 ssp585) scenarios. CMIP6 data provided downscaled temperature precipitation, while GAEZ framework translated these climatic inputs into indicators, enabling spatially explicit analyses land suitability. Projections indicate significant warming, with mean annual temperatures expected rise between 1.13 °C 4.85 end century. Precipitation levels are anticipated increase overall, although spatial variability may challenge availability some regions. LGS projected extend, particularly southern southeastern UBNB, enhancing potential areas. However, faces considerable declines; ssp585, highly suitable area drop 24.21% 13.31% 2080s due thermal stress. highlights intricate relationship variables productivity. Integrating provides quantified insights These findings offer a foundation developing adaptive strategies safeguard food security optimize use vulnerable

Abstract High Asian mountain water resources, which serve as a lifeline for downstream communities, are vulnerable to warmer future climates. Following the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) 3b protocol, changes in mean and extreme streamflow of Jhelum River under shared socioeconomic pathways (SSPs) SSP1-2.6, SSP3-7.0, SSP5-8.5 were quantified. For this, successful calibration validation eco-hydrological Soil Water Integrated (SWIM) against observed 1999–2004 1994–1999, respectively was completed. Then, SWIM forced with bias-adjusted ISIMIP3b historical (1985–2014) (2016–2100) datasets. Climate change analysis suggests warming 0.9 ºC, 5.7 7.5 ºC per century SSP5-8.5, whereas substantial wetting 329 mm, 665 1258 mm relative period. Seasonal temperature reveal that during monsoon increase more pronounced specifically 5.78 precipitation also increased markedly 20.84% season far climate high-end scenario SSP5-8.5. Subsequently, ensemble suggest an low flows (89% February) but decrease high (37% June) all SSP scenarios, Further, 30-year return level will near-future (2016–2043), mid-future (2044–2071) far-future (2072–2100) climates ranging from −7.01% −9.87%, − 7.22% 13.35%, 9.41% 26.60% five models consideration imply reduction likelihood or magnitude river flow events. The outcomes this study advance our knowledge discharge dynamics Basin change, facilitate better management precious resources.
