Abstract
Climate variability and extremes are among the problems prevailing in most parts of Ethiopia. The influence of climate variability is very high for Ethiopian's especially for an agrarian, society where frequencies of extreme events are increasing. This study Analyzethe spatial and temporal trend, farmers’ perception and adaptation strategies for climate variability in Borena District using time series rainfall data of CHIRPS for the period 1981–2018 and temperature data worldClim from 1961-2018. The main objectives of the study are to the trends of rainfall and temperature both in space and time, to evaluate farmers' perceptions of climate variability, to explore impacts and adaptation strategies for climate variability. Primary data were collected through FGD, KII, and observation. Qualitative and qualitative data analyze techniques were employed to the data. Long term Mean, CV, and SD, Maximum and minimum temperatures were used to rainfall and temperature variability. Magnitude and frequency of rainfall and temperature trend were evaluated using Sen‘s slope and Mann-Kendall trend test analyze methods. Trend analyze results showed staticallynon significantincrease in annual rainfall and statically significantKiremt rainfall while,belg rainfall is a decline in all AEZs. Almost all farmers have perceived an increasing amount of temperature and decreasing belg rainfall in all areas. Soil conservation, planting early maturing crops, diversifying livelihood, preservation of food, and seeds storage were used adaptation strategies for climate variability. The finding of this study used as an input for decision-makers takes appropriate measurements in different sectors like agricultural experts, and climate change officers.
