The aim of this paper was to identify the long-term climatic trends and the magnitude of those trends and to analyse drought duration, frequency, and severity in southern and south-eastern Ethiopia based on climatic data (1980-2017). This research is a quantitative research method. The southern and south-eastern of Ethiopia were purposely selected based on a frequent occurrence of drought in the country. Monthly data were obtained from National Meteorological Agency (NMA) of Ethiopia. Mann-Kendall (MK) Test coupled with Sen\u2019s Slope Estimator was used to analyse the trend of climatic data and its magnitude, and Standardized Precipitation Evapotranspiration Index (SPEI) was used to analysis drought characteristics. SPEI of 1-, 3- and 6-month timescales were calculated to understand drought characteristics. The result of the MK test showed that annual rainfall trend had non-significant decrease at all station except at Gode. The trend of annual maximum and minimum temperature is insignificantly increasing. The calculated SPEI revealed drought is more frequent and severe from time to time in the study area. Results showed that the most frequent, severe and prolonged droughts occurred during1999-2017 compared to 1980-1999. Climate change mitigation and proactive drought management approach is highly recommended in order to minimize the risk of drought.<\/jats:p>","DOI":"10.1088\/1755-1315\/477\/1\/012011","type":"journal-article","created":{"date-parts":[[2020,6,9]],"date-time":"2020-06-09T01:14:25Z","timestamp":1591665265000},"page":"012011","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":20,"title":["Drought Frequency, Severity, and Duration Monitoring Based on Climate Change in Southern and Southeastern Ethiopia"],"prefix":"10.1088","volume":"477","author":[{"given":"Magarsa","family":"Abara","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Komariah","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sri","family":"Budiastuti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","reference":[{"key":"EES_477_1_012011bib1","doi-asserted-by":"crossref","first-page":"8","DOI":"10.1016\/j.wace.2014.06.003","article-title":"Droughts in Asian Least Developed Countries: Vulnerability and sustainability","volume":"7","author":"Miyan","year":"2015","journal-title":"Weather and Climate Extremes"},{"key":"EES_477_1_012011bib2","article-title":"Summary for policy makers","author":"","year":"2013"},{"key":"EES_477_1_012011bib3","doi-asserted-by":"crossref","first-page":"418","DOI":"10.1016\/j.jhydrol.2013.10.052","article-title":"Long-term SPI drought forecasting in the Awash River Basin in Ethiopia using wavelet neural network and wavelet support vector regression models","volume":"508","author":"Belayneh","year":"2014","journal-title":"Journal Of Hydrology"},{"key":"EES_477_1_012011bib4","first-page":"148","article-title":"Climate Change Adaptation and Mitigation Measures in Ethiopia Climate Change Adaptation and Mitigation Measures in Ethiopia","volume":"4","author":"Gashaw","year":"2014","journal-title":"Journal of Biology, Agriculture and Healthcare"},{"key":"EES_477_1_012011bib5","author":"","year":"2015"},{"key":"EES_477_1_012011bib6","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1016\/j.gloenvcha.2010.07.013","article-title":"Adaptation to climate change in Africa: Challenges and opportunities identified from Ethiopia","volume":"21","author":"Conway","year":"2011","journal-title":"Global Environmental Change"},{"key":"EES_477_1_012011bib7","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1016\/j.wace.2017.12.002","article-title":"Variability and time series trend analysis of rainfall and temperature in northcentral Ethiopia: A case study in Woleka sub-basin","volume":"19","author":"Asfaw","year":"2018","journal-title":"Weather and Climate Extremes"},{"key":"EES_477_1_012011bib8","doi-asserted-by":"crossref","first-page":"309","DOI":"10.1016\/j.jag.2010.12.002","article-title":"International Journal of Applied Earth Observation and Geoinformation Spatial and temporal assessment of drought in the Northern highlands of Ethiopia","volume":"13","author":"Gebrehiwot","year":"2011","journal-title":"International Journal of Applied Earth Observations and Geoinformation"},{"key":"EES_477_1_012011bib9","author":"","year":"2010"},{"key":"EES_477_1_012011bib10","doi-asserted-by":"crossref","first-page":"23","DOI":"10.1016\/j.agsy.2014.06.002","article-title":"Impacts of climate change and variability on cattle production in southern Ethiopia: Perceptions and empirical evidence","volume":"130","author":"Megersa","year":"2014","journal-title":"Agricultural Systems"},{"key":"EES_477_1_012011bib11","doi-asserted-by":"crossref","first-page":"11","DOI":"10.1016\/j.wace.2016.11.005","article-title":"GIS-based climate variability and drought characterization in Ethiopia over three decades","volume":"15","author":"Suryabhagavan","year":"2017","journal-title":"Weather and Climate Extremes"},{"key":"EES_477_1_012011bib12","article-title":"Drought Emergency Response in Ethiopia -
