Abstract: This study presented an analysis of long-term temperature and precipitation trends in the Dessie Zuria from 1981 to 2022. To monitor climate change in the study area, it was necessary to analyze the trends in temperature and rainfall in particularly. The aim of this study was to assess the monthly and annual rainfall and temperature trends, descriptive statistical analysis, and the impact of climate change in the study area. In this study, CDT, R software, Arc Map, and Excel 2010 were used for data and map preparation, as well as descriptive statistical analysis. The Mann-Kendall and Sen’s slope trend test were to detect trends and the magnitude of change. According to the analysis of average yearly maximum temperature coefficient of variation was varied from 1.9% (Tita) and 4.5% (Guguftu). The average yearly maximum temperature was a non-significant increasing trend at Dessie, Tita and Tebasit station but a significant increasing trend at Guguftu station. The annual minimum temperature coefficient of variation was 13.9%, 19.1%, 10.6% and 15.4% at Dessie, Guguftu, Tita and Tebasit station respectively. The average yearly minimum temperature was a non-significant increasing trend at Guguftu and Tebasit station but a non-significant decreasing trend at Dessie and Tita station. The monthly rainfall coefficients of variation were moderate variability in July and August, but other months were high variability. The annual rainfall was a non-significant increasing trend at Dessie and Guguftu station but significant increasing trend at Tita and Tebasit station. The slopes of annual rainfall were changed at 4.7mm, 7.4mm, 6.2mm and 6.1mm per year at Dessie, Guguftu, Tita and Tebasit station respectively. The slope of average annual minimum temperature was changed at -0.02°C, 0.01°C, -0.004°C and 0.014°C per year at Dessie, Guguftu, Tita and Tebasit station respectively. The slope of average annual maximum temperature was increased at 0.006°C, 0.03°C, 0.005°C and 0.01°C per year at Dessie, Guguftu, Tita and Tebasit stations in the study area respectively. This situation of temperature increment was influenced by climate change in the study area. Therefore, since the results of this work are necessary, relevant stakeholders must adopt policies that help prevent climate change.

Abstract: This study was entitled with: the impacts of traditional stone lines/kabi lines/ in association of soil management practices of agronomic erosion controls on soil physico-chemical properties at Ifabas / Jarra/ community watershed, Tullo Weroda west Harareghe zone Oromia Regional National State Ethiopia. The objectives of this study were to examine the effects of TSLs with fertilizers application, crop types and crop patterns on soil physico-chemical properties of CFLS with TSL in comparison to NCFLS and to observe their correlations existed between them; and to investigate the variations of C/N ratios between CFLS with TSL and \NCFLS. CRBD was purposefully used in provided an equal chances of statistical probability distribution of EUs, SPs, and OUs. The total of 54 CSSs were collected from the three sub-watersheds of Ifabas community watershed for laboratory analysis. Moreover, the total of 54 disturbed soil samples were collected in separate to determine soil BD and soil MC. Soil samples were collected at 0-15 cm soil depth by used local available and prepared auger from metal pipe. Its volume is 396.312 cm3. Soil samples were replicated three times to approach the accuracy. Laboratory analyzed output of soil data were subjected to EXCEL2013 software and multiple ANOVA following the GLM of Multivariate procedures of SPSS version 23. The study were observed the variations of ST, SOC, TSN, ASP, and soil pH, SOM, MC and BD and C/N ratios available between CFLS and NCFLS. The results of the study in B-I had showed that, the average values of the soil BD, soil MC, silt and, sand soil, TSN, SOC, SOM and soil pH were the higher inside CFLS with TSL (0.24g/cm3, 39.76%, 31.13%, 31.82%, 0.20%, 2.29%, 3.94% and 6.72 ratio) than NCFLS (0.16g/cm3, 26.96%, 24.21%, 27.38%, 0.19%, 1.24%, 2.13% and 6.61 ratio). The findings of the study in B-II had revealed that, the average values of soil BD, soil MC, soil pH and clay soil were the lower under CFLS with TSL (0.12g/cm3, 24.5%, 6.93 ratio and 32.58%) than in NCFLS (0.24g/cm3, 30.62%, 6.72 ratio and 38.35%). The results of the study in B-III had indicated that, the average values of the soil MC, sand soil, SOC, SOM, TSN, and ASP were the higher under CFLS with TSL (30.76%, 39.40%, 1.71%, 2.95%, 0.33% and 24.56ppm) than NCFLS (19.32%, 38.19%, 1.13%, 1.95%, 0.18% and 13.57ppm), In general the study results had showed that TSL structures, CFS and CGPS have the positive effects on improving of soil physical and chemical properties as comparted to NCFLS.
