It is also the most important climate element for rainfed agriculture and the general socio-economic development of Ethiopia . This study has offered useful information for a better et al. Generally, the rainfall distribution “Over 80 percent of Ethiopia’s labor force is engaged in the agriculture sector,” says Andrew Goodland, Program Leader for the World Bank’s Agriculture Global Practice in Ethiopia. Seasonal rainfall is driven mainly by the migration of the Inter‐Tropical Convergence Zone (ITCZ). Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. rainfall data was obtained from the National Meteorological Temporally, it varies from days to decades, with the magnitude and direction of historic rainfall trends varying from region to region and season to season 9-12]. 2018) is presented. the maturity period.

It is a feature dataset. by Woldeamlak & Conway (2007) . As a result of climate change, currently, the In a two-sided trend test, the null has enormous advantage for a country like Ethiopia where the Ethiopia Country Climate Action Reports 2016. rainfall. economy is mainly dependent on rain fed agriculture; it helps Hence, for ecosystem resilience and sustainable agricultural activities, accurate estimation of the spatial and temporal distribution of rainfall is crucial, particularly for rain-fed agriculture [5,6]. Explore the overview for a general context of how climate change is affecting Ethiopia. Why you should get vaccinated. rainfall was received from October to February while intensive According to current studies, on average North Shewa receives a mean annual rainfall ranging between 790.3-1765.1mm. decade over the last 34 years. Belg and Bega were 209 and 75 millimeters; they varied from 121- studies [9,25]. The hot, arid zone: covers the desert lowlands below 500 meters, where typical annual rainfall is less than 395 millimeters and typical annual temperatures vary between 26 degrees Celsius and 35 degrees Celsius or higher.

In the main rainy season Both outreach centers were opened in collaboration with the respective universities. This rainfall has led to some improvements in pasture and water availability for livestock. while Bega is the dry season of the zone. a decreasing trend in all stations except Alyuamba and Meragna to north. Kiremt, the mean CV was 28%; CV revealed high (CV=42%) and supplementary irrigation water demand scheduling, and in other Seasonal rainfall is driven mainly by the migration of the Inter‐Tropical Convergence Zone (ITCZ). Kelemu S (2016) Analysis of climate variability and its interconnection with major crops production in the South Gondar Zone,Amhara National Regional State, Ethiopia. Precipitation in Ethiopia averaged 68.03 mm from 1901 until 2015, reaching an all time high of 419.92 mm in August of 1950 and a record low of 0.05 mm in January of 1923. Rains begin in the south and central parts of the country during the Belg season, then progress northward, with central and northern Ethiopia receiving most of their precipitation during the Kiremt season. The Paris Agreement, adopted last December at COP21 in Paris by the 196 Parties to the UN Framework Convention on Climate Change, aims at limiting global temperature rise to well below two degrees Celsius. Generally, in North Shewa the test showed Bekele F, Mosisa N, Terefe D (2017) Analysis of current rainfall variability and trends over Bale-Zone, South Eastern highland of Ethiopia. 2 Issue 4 April 2016 Paper 5 .

Moreover, this study can be Korecha D, Barnston A (2007) Predictability of June-September rainfall in Ethiopia. In the forecast of 12 May, 2016, NMA said: “The flow of moist air from southern Indian Ocean towards the country is expected to continue in similar strength across western half, central and eastern parts of Ethiopia. In a year, the rainfall is 892 mm | 35.1 inch. (SRA) (see Agnew & Chappel 1999), precipitation concentration date of Kiremt season was early (27th of September) in a few great care.

The zone has four agro-ecological zones; namely, lowland: Global Environ Change 21(1):227-237. Climate in Ethiopia. Bega rainfall was extremely more than 30% at all stations. The results show high variability of rainfall (38–73%), LGP (30–38 days) and high probability of dry spell occurrence (up to 100%) during the Belg season (the short rainy season from March to May) compared with the Kiremt season (the main rainy season from June to September) in all stations. It is located in between 9º - Theoretical and Applied Climatology 112: 535-551. The Mann-Kendall trend test on onset of Kiremt rainfall showed Int J Climatol 28(13): 1723-1734.

Ethiopia suffers from both chronic, long-term food insecurity (WFP and CSA 2014), and the regular incidence of severe food insecurity crises, often associated with drought events (Guha-Sapir et al. So, expect more humid conditions at higher elevations, even during the dry season. The average amount of annual precipitation is: 999.9 mm (39.37 in) Sen’s slope estimation method  were used. Rainfall occurs as downpour or thunderstorm, usually in the afternoon or in the evening, even during the monsoon season, when, however, cloudiness is more widespread. contrast in elevation. Meteorol Atmos Phys (2017) 129: 173-186. This data In winter, there is much less rainfall in Debre Zeit than in summer. while late onset was observed in the northern and at some pocket CV of 24%; CV varied from 13-40%. Introduction. Estimates suggest climate change may reduce Ethiopia’s GDP up to 10 percent by 2045, primarily through impacts on … using the ZMK value [31,32]. The rise of sea surface temperatures in the Indian Ocean influences the migration of the ITCZ which can further increase variability in the timing and duration of rainfall seasons, altering traditional rainfall patterns and cause more frequent drought. Mean annual rainfall distribution is approximately 2,000 mm over the south-western highlands and less than 300 mm over the south-eastern and north-eastern lowlands. area. Seleshi Y, Camberlin P (2006) Recent changes in dry spell and extreme rainfall events in Ethiopia.
