| dc.description.abstract | Wag Himra administrative zone in general; Gazgibla district, in particular, was known for the excessive degradation of natural resources and recurrent drought. Soil and water conservation practices were exhaustively implemented through an integrated watershed management approach to rehabilitate the environment at the same time to adapt climate-related shocks. But the contribution of those practices for climate change adaptation and mitigation as well as barley yield is not studied. Thus, this research is aimed to quantify the carbon stock trapped by the soil and water conservation practices, assess barley yield and farmers’ perception on climate change adaptive strategies in Miyo-Hadi watershed (covered 663.4 ha). Soil laboratory analysis, yield assessment, and household survey were deployed to answer the research questions. The data collected from 98 households and the results of soil laboratory test (27 soil samples) were analyzed using the SPSS version 23 software. Almost all of the households (93%) perceived the existed climate change in the area; and recurrent drought, pest disease, snow, and frost were among the events. Most of the farmers (65.3%) perceived that the implemented strategies (SWCPs, infrastructure, soil fertility, credit & saving, and capacity building) were helpful to adapt climate-related shocks. The mean value of most of the soil physicochemical properties (Av-P (9.9±2.11**), Av-K (68.76±12.39), CEC (43.19±3.35**), clay content (13.89±1.3*), OM (1.52±0.223), SOCS (28.45±3.81), OC (0.88±0.13), TN (0.22+0.17**) and barley yield (13.67±0.47**) in the treated part of the watershed was higher than the untreated part. Similarly, the mean value of most of the soil physicochemical properties (Av-P (9.42±2.0*), Av-K (66.8±4.81*), SOCS (28.41±6.17*), OC (0.84±0.17*), OM (1.44±0.28*), TN (0.285+0.18**) barley yield (11.78±0.94**) and clay content (13.67±0.7*) were found to be high in lower slope gradients than steep slopes. It can be concluded that as a holistic approach watershed management in general and soil & water conservation practices specifically have a meaningful role in the area in terms of minimizing soil loss, improving soil property & increasing barley yield. On the other hand; cut & carry system, avoid total harvest/removal of crop residue, improved agronomic practices, proper land use, enhanced sense of ownership & policy enforcement were highly recommended to maximize the benefit & assure sustainability.
