Power Data Access Viewer-Based Meteorological Drought Analysis and Rainfall Variability in the Nile River Basin

Advances in Meteorology, Journal Year: 2024, Volume and Issue: 2024, P. 1 - 12

Published: March 5, 2024

Meteorological drought poses a frequent challenge in the Nile River basin, yet its comprehensive evaluation across basin has been hindered by insufficient recorded rainfall data. Common indices like standard precipitation index, coefficients of variation, and concentration index serve as pivotal tools gauging severity. This research aimed to assess meteorological status using Power Data Access Viewer product Bias correction procedures were implemented refine monthly data for Bahirdar, Markos, Nekemt, Muger stations, resulting notable improvements coefficient determination ( $R^2$ ) that increased from 0.74 0.93, 0.72 0.89, 0.71 0.96, 0.69 0.84, respectively. The average spatial distribution was classified extremely wet (3.81%), severely (9.01%), moderately (7.36%), near normal (9.97%), (21.20%), (17.11%), (31.54%). Approximately 10.33% situated regions characterized high variability, while around 21.17% located areas with notably irregular index. Overall, this study sheds light on prevailing patterns emphasizing significance understanding managing these phenomena sustainable development region.

Kobo-Golina River, Upper Danakil Basin, Ethiopia. It is crucial to understand the spatiotemporal distribution of blue water (BW) and green (GW) for optimal use resources, especially in data-scarce regions. This study aims evaluate extent which future climate changing, its impact on blue-green resources area. Projected changes were predicted based latest Coupled Model Intercomparison Project Phase 6 (CMIP6) Global Climate Models (GCMs) three periods (2015–2044, 2045–2075, 2076–2100) under two shared socio-economic pathways (SSP2–4.5 & SSP5–8.5). Compromise programming technique was employed rank select best performing GCMs. The multi-variable calibrated SWAT+ model forced with projections from top-ranked CMIP6 GCMs ensemble simulate projected Compared baseline period (1984–2014), declined while exhibited an increasing trend all SSPs. also noted that spatial BW GW remains uneven Precipitation significantly impacted than resources. provides valuable insights into utilization recent coupled hydrological models better simulation Blue-Green basins changing climate.

Adoption of climate resilient agricultural practices among the Giriama community in South East Kenya: implications for conceptual frameworks

Frontiers in Climate, Journal Year: 2023, Volume and Issue: 5

While quantitative studies are robust at assessing the extent of climate change adaptation, and statistical relationships among variables involved, qualitative also essential to understand social rationales underlying variables, identify roles that have been overlooked or hard measure. This study investigates factors influence adoption resilient agricultural practices by resource-poor Giriama farmers in southeast Kenya, with a view understanding why some smallholders from this cultural group adopt practices, while others do not. Data was collected through in-depth interviews 30 farmers, 15 whom had adopted farming recommended experts, not any those practices. The adopters were market-oriented, tended individual land tenure, higher levels experience farming, slightly larger farm sizes, middle high school education levels, be younger. They access extension, inputs, their off-farm activities related supply chains. Non-adopters farmed entirely for subsistence, on communal leased land, less formal education, adhered strongly beliefs Their income unrelated agriculture. More males, many non-adopters female. Particular taboos inhibited several such as planting hybrid maize, keeping dairy goats, using improved goats Kenyan Alpine breeding purposes use water conservation structures crop production. Further, information explains how ownership, gender, culture, interrelated, ways necessarily obvious analysis. thus highlights issues need considered conceptual frameworks underpinning both studies, particularly they interact, order provide knowledge policy programs intended enhance smallholder farmers' adaptive capacity.

Projected changes in daily precipitation, temperature and wet‐bulb temperature across Arizona using statistically downscaled CMIP6 climate models

International Journal of Climatology, Journal Year: 2024, Volume and Issue: 44(6), P. 1994 - 2010

Published: March 20, 2024

Abstract To evaluate future changes in the climate system, outputs from coarse‐resolution global models (GCMs) need to be downscaled a finer scale, making them more directly applicable for impact assessment. Here we focus on examining projected of three key variables (precipitation, air temperature, and wet bulb temperature) across Arizona (south‐western United States). We use daily GCMs sixth phase Coupled Model Intercomparison Project (CMIP6) bias correct downscale 4‐km resolution. Through leave‐one‐out cross‐validation, compare various correction methods identify that empirical quantile mapping approach performs best regardless variable. Then, analyse bias‐corrected two periods (Mid‐of‐Century: 2015–2048; End‐of‐Century: 2067–2100) with respect 1981–2014 period, under four shared socioeconomic pathway scenarios (SSP1‐2.6, SSP2‐4.5, SSP3‐7.0 SSP5‐8.5). Our results show Arizona's is become overall warmer wetter, so towards end this century higher emission scenarios. Additionally, our findings project an increase temperature cooling degree days, implying ongoing warming climate's potential impacts public health economy.
