and time (season, year). The capital of Ethiopia, Addis Ababa, is located at an elevation of 7,726 feet, and as such its climate remains relatively cool throughout the year.

Spline, Kriging, and inverse distance weighting interpolation techniques were assessed using daily rainfall data and digital elevation model using ArcGIS. To this end, therefore; the SWAT model was applied to model the amount of water converted to spatially and temporally distribution of rainfall in the country is irregular and erratic [6]. Distribution Unrestricted Date of Publication August, 2017 Abstract In this scientific research report, monthly, seasonal and annual area weighted rainfall time series for all-India, 5 homogeneous regions and 30 meteorological subdivisions for the period 1871-2016 are constructed on the basis of a fixed and well distributed network of 306 rain gauge stations over India. trailer It remained to be seen whether this plan would improve the state of Ethiopia's forests. Work performed under USGS contract 03CRCN0001, USA. Farmers’ perceptions of average temperature and rainfall changes in Ethiopia over the last 20 years from 2004/2005 (n = 1000). Figure 2 shows rain rate distribution for ten main sites of Ethiopia versus percentage of exceedance of time of the 0000007720 00000 n This has been observed in a different study by Nair et al. The economy of Ethiopia depends largely on rain-fed agriculture, which is highly sensitive to variability of rainfall across time and space. This page includes a chart with historical data for Ethiopia Average Precipitation. 0000011098 00000 n The rainfall pattern is also named according to their rainfall distribution [18-22]. As a country whose economy is heavily dependent on low‐productivity rainfed agriculture, rainfall trends are often cited as one of the more important factors in explaining various socio‐economic problems such as food insecurity. Climate change is increasing the occurrence and magnitude of rainfall extremes that cause increased drought and flood risks (Chen et al. 0000024914 00000 n Analyses of rainfall variability utilized rainfall anomaly index, coefficients of variance, and probability analyses. The distribution of mean number of days having measurable (≥0.1 mm) rainfall (not shown), follows a similar pattern, 1 with western and central Ethiopia receiving measurable rainfall 70%–90% of the days. 0000230431 00000 n 0000007299 00000 n But you MUST plan it all in one package and making changes may be very costly. The distribution of the rainfall in time and space is expected to be generally poor over several areas especially during the month of October and the peak month of November. 3.11 ) may be higher than the kiremt , Source: Bryan et al. Belg (“small rainfall” in March – May) rain makes a considerable contribution to the annual total in the central and eastern stations of the region. In the month of December sunny and dry conditions are expected to prevail over several places in the country as the The major rainfall during the rainy season, between June and September, accounted for 75% of the total annual rainfall.

The rainfall is highly variable both in amount and distribution across regions and seasons (Tesfaye, 2003, Tilahun, 1999; Mersha, 1999). The average annual temperature in Debre Zeit is 18.7 °C | 65.7 °F. 34-40. 0000024338 00000 n Based on weather reports collected during 2005–2015. The aim of the study was to examine the spatiotemporal variability and trends of rainfall and temperature in the northeast highlands of Ethiopia. 0000125762 00000 n Understanding factors such as rainfall and erosivity is therefore of utmost importance for soil erosion risk assessment and soil and water conservation planning. 0000006050 00000 n 0000230215 00000 n In late 1990, Addis Ababa was in the process of launching the Ethiopian Forestry Action Plan (EFAP) to improve woodland conservation, increase public participation in reforestation projects, and prevent further depletion of existing forest resources. 0000027612 00000 n 0000021046 00000 n 2 DESA Working Paper No. By regressing annual watershed rainfall on time, results from the one‐sample t‐test show no significant changes in rainfall for any of the watersheds examined.

Cheung, UNEP Division of Early Warning and Assessment‐North America, National Centre for Earth Resources Observation and Science, Sioux Falls, SD 57198, USA. 0000019608 00000 n Kiremt rain account for 50–80% of annual rainfall totals in Ethiopia, which has high contribution to agricultural productivity and major water reservoirs. In this study, we evaluated the spatial distribution and temporal trends of rainfall and erosivity for the Eastern Africa region during the period 1981–2016. Copyright © 2008 Royal Meteorological Society. As the study area is characterized by a wider altitudinal range , the difference in the spatial distribution of rainfall amount could be attributed to orographic nature of rainfall (Viste et al., 2013, Dinku et al, 2007). Analyses of rainfall variability utilized rainfall anomaly index, coefficients of variance, and probability analyses. �7m���7�-'ܭ��k�r�Q���G�J[H446��o��t���2iEK�$�@M1ddf�ڐq3$cB��(��\W՛�f+U\ګx,G�&fcsc��N���4㤝Y[^_���x,GN/���e�S%tB�D��=ze��ܐ�WtB�x���)q;�#��l�=m��^�%EK��J>�['��y�oo��A��Nƒ�I��Z%��D�u�s,'\7. Five Year Growth and Transformation Plan 3.
