Soil degradation due to soil erosion is one of the major environmental threats in developing countries. In all three, 1984 stands out as the driest year on record due to very low rainfall during the Krempt season, whilst 1999's Belg season was the driest on record. However, spring droughts have occurred more frequently in all parts of Ethiopia during the last 10–15 years. Along the Eritrean coast and, for a few kilometers inland, night advection fogs may, commonly form and turn into morning drizzle, integrating.

The empirical analysis also confirmed that the basin losses a total of about 89.6 Mt of soil annually. This study aimed to address the information gap by estimating the burden and seasonality of medically attended influenza like illness in Ethiopia. Towards Ethiopia's borders, elevations decrease and temperatures rise accordingly. Further study need to be considered to identify potential risks and improving the surveillance system to continue early detection and monitoring of circulating influenza virus in the country has paramount importance. Especially, ambient temperature plays a major role in the life cycle of the malaria vector.

The models were visually compared with the map of potential vegetation. Therefore, there is a need for more research on suitable coffee shade trees, exploring moisture stress and high-temperature resistant varieties, more attention to water conservation strategies, and moving coffee establishments at higher elevations. Results show that both minimum temperature (Tmin) and maximum temperature (Tmax) have a large number of breakpoints compared to rainfall. Only, on the coast, namely at Djibouti and Massawa, the winter, rains account for most of the annual precipitation. start and end in different years. CLIMATE VARIABILITY AND CHANGE IN ETHIOPIA: SUMMARY OF FINDINGS | v ACRONYMS. The estimated mean annual influenza positive case proportion and ILI incidence rate was 160.04 and 52.48 per 100,000 population. Low Temp: 48 °F. Several papers have been published on different issues regarding the climate of Ethiopia or of some specific region. Among the climatic parameters considered in this study, long time series were available only for temperature and, precipitation data. In winter, in fact, the contrast between the, thermal anticyclone of western Asia and Egypt and, equatorial low pressures determines the presence of trade. Method: Laboratory confirmed influenza virus (influenza positive case) among ILI and SARI suspected case was 25% (1130/4426) and 3% (36/1289). The procedure of sedimentation begins from the very first moment of the seizing of water in some random supply. located in the adjoining territories of Djibouti, Eritrea, Somalia, and Sudan, were considered as well (Table, order to account also for the conditions right beyond the, Ethiopian borders and thus to improve as much as possible.

This paper explores the different components of the adaptive capacity of households in the Central Rift Valley (CRV) of Ethiopia and quantifies their relative contributions. Unfortunately, only very few data of Fantoli (, century. Satellite and reanalysis climate products were used to fill in the missing data in the time series after a thorough evaluation and bias correction to the latter dataset. The development of the parasite within the mosquito (sporogonic cycle) is also dependent on temperature. minimum temperatures are for the same points and girds, but cover the period 1981–2011. These trends are projected to continue to 2050 according to the Geophysical Fluid Dynamics Lab model using the A1B scenario. The best map was obtained with the method of the humidity index calculated with the evapotranspiration estimated with MT with a value of wet month of 0.65. The paper ends with a discussion of the major influences on rainfall variability over the Ethiopian Highlands: the El Niño-Southern Oscillation - El Niño events tend to be associated with lower than average rainfall; Atlantic, Indian and Pacific Ocean sea surface temperatures play a varying role in different seasons; the strength of the Indian Summer Monsoon; and the frequency of several tropical depressions over the Southwest Indian Ocean. Results also suggest that future research and development works should give priority for developing early maturing, acidic and waterlogging soil tolerant malt barley varieties. These latter were included as well in order to, also, a westward gradient is rather evident too. rainfall, based on quality controlled station observations, decreased by 15–20 percent across parts of southern, southwestern, and southeastern Ethiopia. There is not a statistically significant trend in observed mean rainfall in any season in Ethiopia between 1960 and 2006. The highest average and absolute rainfall intensities, are recorded at Gambela (89.4 and 181.4 mm/24 h, respec-, tively), whereas the lowest values are measured at Elidar and, Gewane in the Afar triangle. Annual, June–September (Kiremt), March–May (Belg) rainfall totals exhibit low inter-annual variability. The mountains located in the center of Ethiopia have a climate with a rainy season and a dry season. In the 2007 NMA report, temperature data are considered, maximum temperature, respectively, are presented. At 1,000 m, the mean values are close to 30. mainly, in the steppe areas and the Danakil Desert (Fig. To date little work has been done on climate reconstruction in Tigray and Wollo, however, a number of ongoing studies in the area using palaeosoil analysis, archaeological techniques and lake level reconstruction will help reveal the magnitude of past climate variability in the region. temperature, identifying significant reductions in rainfall and increases in temperature over time in many areas of Ethiopia. of the Equator.

Along the, Eritrean coast and in Ogaden, the largest variability of annual, precipitation is found (Aseb CV = 127 %), whereas the, variability is observed in the central highlands (Table, Rainfall intensity was investigated using daily data, recorded at 26 stations. highlands and the lowlands close to the Sudan border receive, more than 7 h of mean daily sunshine, whereas from, to the southeast of the country the respective value increases, commonly recorded in Tigray and Ogaden. These parameters were also used to update the K, Ethiopian territory. In fact, at Addis Ababa, the temperature change is negligible, sured at Mekele, Alamata, and Arba Minch (0.1, Eight meteo-stations have longer time series starting in, shows a higher increasing rate as far as the 1980s, whereas, worth noticing that for these stations, the mean temperature, increase is mainly due to the contribution of the minimum, temperatures that increase at a rate twice as much the. The annual precipitation, averaged all across the country, is 817 mm but, given the complex physiography and the, masses and winds, a large diversity is observed among v, regions. Based on this information increased ability to monitor and detect multidecadal variations and trends is critical to begin to detect any observed changes and understand their origins. whereas annual rainfalls tend to decrease with the spring, Ethiopia is among the largest countries of Africa and it is, characterized by a wide variety of landscapes, with marked, contrasts in relief and altitudes ranging from about 155 m, below sea level of Assale Lake, in the Danakil depression, to, reasons and given its geographic position close to the, equator and the Indian Ocean, the country is subjected to, large spatial variations in temperature and precipitation (see, circulations as well as by the complex topography of the, country. In the tropical climate region with a dry season in winter, minimum temperature during the perturbed phase (July or. precipitation as they explain only 31 % of its variability.

The results can be useful for policy and decision making to ensure land resources are used in the most productive and sustainable ways and solve the mismatches between current land use and land suitability for malt barley varieties in the country. Obviously, the spatial distribution of humi, is tightly correlated with precipitation.

This study suggests the need for an integrated assessment and enhancement of adaptive capacity with all its components rather than focusing only on asset possession as an indicator of adaptive capacity. National Meteorological Services Agency, Addis Ababa. Ethiopia. The minimum temperatures increased at a higher rate than the maximum temperatures during winter, summer, autumn and also at the annual timescale. Hydraulic conductivity is higher for fracture dominant aquifers than weathered rock aquifers. WMO; Posted 20 Mar 2017 Originally published 20 Mar 2017. Their occurrence in geological formations and water quality are the main issues for sustainable utilisation. However, high-quality, dense meteorological datasets are hardly available in many parts of the world. Our results suggest that local level investigations such as this one are important in developing context-specific climate change adaptation and agricultural planning, instead of coarse-scale national level analysis guiding local level decisions. Though, marked differences are observed for the average annual and, the Omo valley, the climate of Ethiopia is generally very, pleasant and among the most equilibrate of the African, continent since the temperatures are mitigated by the high, average elevation. FAO Plant Production and Protection Series No. 12 stations out of 20 show a negative trend; however, in order to reduce the weight of the gaps scat-, tered across the data set, the trend analysis has been, time series has been constructed by averaging the annual, precipitation at all the stations for each year. The study is based on gridded monthly rainfall and maximum and minimum temperature data series at a resolution of 4 × 4 km which were obtained from the National Meteorological Agency of Ethiopia for the period 1983–2016. Climate change is a very important issue with, agriculture and hence the social and economic development of the country. These trends are projected to continue to 2050 according to the Geophysical Fluid Dynamics Lab model using the A1B scenario. Averages are for Addis Ababa Airport, which is 4 miles from Addis Ababa. The index score for major components shows that intangible variables such as institutions and entitlements, knowledge and information, and innovation contributed to adaptive capacity better than decision-making and governance and asset-base. Nationally, 2009 was the second driest year, surpassed only by the historic year 1984. Climate change in Ethiopia Climate change is already taking place now, thus past and present changes help to indicate possible future changes. It takes about 9 to 10 days at temperatures of … At the annual scale, maximum and minimum temperatures significantly increased in over 33% of the Basin at a rate of 0.1 and 0.15 °C per decade, respectively; however, the western part (12%) of the Basin experienced declining trends on annual and seasonal timescales. The Incidence rate of ILI was higher in the age group of 15-44 years of age ['Incidence rate (R) = 254.6 per 100,000 population', 95% CI; 173.65, 335.55] and 5-14 years of age [R = 49.5, CI 95%; 31.47, 130.43]. The coldest winter (January to March) was in 1984 with an average temperature of 18.9 °C. This study was conducted to examine the trends of past precipitation and temperature extremes over three eco-environments in Ethiopia. For temperatures, the theoretical, monthly solar radiation was considered as well. 9. Diverse rainfall and temperature patterns are largely the result of Ethiopia's location in Africa's tropical zone and the country's varied topography.
