Abstract

Abstract: The objective of this study is to identify the adoption level of this agricultural technology affected by climate change and to confirm the relationship with conservation agriculture. The assessment was carried out using the Mann–Kendall trend test and the Sen's slope is used. The collected data were statistically analyzed by Statistical Down Scaling Model Software to compare the observed and climate model scenarios of temperature and precipitation. According to the results of the study, earth analysis of the 2001–2021 data revealed that 26.68% of the land area has improved productivity, 67.38% of the territory is stable, 5.93% of the area has degraded productivity, and 0.02% of the area has no productivity data. The study result indicated that there is variability, a decrease in rainfall, and a rise in temperature in the area. The Mann–Kendall and Sen's slope test findings for the total maximum annual rainfall reveal a P -value of 0.307, indicating that there is no pattern in the series or variability of rainfall and that there is a diminishing trend in the rainfall data. The study's findings may help decision-makers and water managers provide more sustainable strategies and methods for managing water resources. HIGHLIGHTS: Crucial information for smallholder farmers in rural regions. To explain how conservation agriculture might assist us to lessen the influence of events. It also offers a comprehensive answer to Ethiopia's major issue. Maintaining the cultivated land will help local residents by reducing the effects of high-intensity raindrops. To pinpoint the key socioeconomic elements that influence the adoption of conservation agriculture. Graphical Abstract
