However, it hasno significant coverage compared to other seasons. However, some parts of thecountry enjoy a temperate climate. Simulations using the Variable Infiltration Capacity (VIC) hydrology model indicate that a drier and warmer future will shift the location of snow line to higher elevations and reduce the number of days with precipitation falling as snow. 2011; Pachauri et al. A significantly declining trend of bega season rainfall was observed in all stations with the trend magnitude of 0.61 mm/year and 7.50% in GIN station to 0.21 mm/year and 56.40% in DBS station. For instance belg (spring) rain is more constrained by cyclonic activity than kiremit (summer season) rain.

In this study, to manage the data quality, data series were plotted in order to identify the outliers. This is because the temperature and the amount of energy reaching the surface isdirectly related with the directness of the sun.The direction of rain bearing winds (leeward or windward side) also determines the temperaturevariations in mountainous regions. Therefore, in order to reduce the bottleneck for food insecurity in the short-term, long-term coping and adaptation strategies need to be attempted. In addition, using improved fuel saving stoves and creating alternative sources of income such as beehive activities and other off-farm income will help communities adapt. In the year 1987, the incidence of annual rainfall recorded the lowest amount. . Topographic map of the Ziway Lake Basin. You can download the paper by clicking the button above. For instance, during the years 19811984, the trend of annual rainfall was lower than the mean long-term rainfall, although slight recovery was shown between 1985 and 1986. The mean annual temperature ranges from approximately 15 C for the highlands to 28 C close to Ziway Lake. Continuously increasing temperature, together with the variability and fluctuation of seasonal and inter-annual rainfall is a root cause for the decrease and fluctuation of crop production. Improving awareness about climatic variability and its adverse implications for their environment enables farmers to modify their resources and management practices and make efficient use of available water for better crop production. 2009). Do we have dynamics in temperature and rainfall in Ethiopia? Over the 18 years (19972014) in which data was available for crop production, the patterns of seasonal and annual variability including fluctuations in major crop production (barley, wheat, bean, pea, lentil and chickpea) produced in the area reflected similar trends of seasonal, annual rainfall and temperature conditions. During this period,the Northeast Trade Winds carrying non-moisture-laden dominates the region. The Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS) products were used to analyze drought patterns and severity in Ethiopia's 14 homogenous rainfall zones using CHIRPS satellite rainfall data. Overall, the five years moving average trend of average annual temperature of the study watershed is increasing by about 0.95 C. 2013; Irannezhad et al. Such studies ignored the localized trends of rainfall and temperature, particularly in most highlands of Ethiopia. All year-round rainfall regionIt has many rainy days than any part of the country. The elevation ranges from 2,747 to 3,674 m a.s.l. Fine-scale hydrological simulations driven by the global model results should reproduce these trends. 3.1 Spatial distribution of rainfall in Ethiopia. The focus of this study is to investigate the spatiotemporal variability and trends in rainfall and temperature in Alwero watershed in the western part of Ethiopia using a dense network of 4 4 km gridded data (558 points) reconstructed from weather stations and meteorological satellite records which spatially covers the watershed. Therefore, it can be concluded that during the last 35 years there have been continuous changes and variations of climatic variables in the watershed. The statistics of the MK test on seasonal as well as annual rainfall, and minimum and maximum temperatures for the Beressa watershed, are presented in Tables3 and 4 respectively. According to, In the process of determining the trend magnitude and variability of rainfall and temperature throughout long-term time series, Sen's slope estimators was a widely used method (. In the observations, warm spell duration, warm day-, and warm night frequencies exhibit statistically significant positive trends. Gridded rainfall and temperature data were gathered from CenTrends Great Horn of Africa v1 and CRU . Bean, pea, chickpea and lentil production are particularly related to kiremit rains in all stages because these crops are sown in the second week of June. Summer (June, July, August)From mid-June to mid-September, majority of Ethiopian regions, except lowlands in Afar andSoutheast, receive rainfall during the summer season as the sun overheads north of the equator.High pressure cells develop on the Atlantic and Indian Oceans around the tropic of CapricornAlthough, the Atlantic contributes a lot, the Indian Oceans is also sources of rainfall. Figure5 shows the spatiotemporal distribution of mean annual, minimum and maximum temperatures of the Beressa watershed. 2011; Jain & Kumar 2012; Suryavanshi et al. Journal of Water and Climate Change 1 December 2019; 10 (4): 799817. Results of the ensembles for CMIP3 and CMIP5 are generally indistinguishable regarding projected impacts on hydrology. Most of the studies about rainfall and temperature characteristics are limited by short-term and long-term time series available for most parts of the regions. A climate impact study in the Upper Blue Nile, North American Climate in CMIP5 Experiments. During this season, Northeasterly windsoriginating from the landmass of Asia dominantly prevail Ethiopian landmass. During these seasons, rainfall is more highly variable than the main rainy season of the area. 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 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. The location of Ethiopia at close proximity to equator, a zone of maximum insolation,resulted for every part of the country to experience overhead sun twice a year. 2014). Other studies have focused on very limited stations and arrived at a conclusion regarding the characteristics of spatial climatic variability for entire regions (Gamachu 1988; Meze-Hausken 2004). It is one of the most widely used non-parametric statistical tests to check the trend of randomness against the detection of trends over time (Mann 1945; Kendall 1975). Annual total precipitation significantly reduces while the frequency of exceedance of the 95th and 99th percentile thresholds increases significantly. In Ethiopia, as in allplaces in the tropics, the air is frost free and changes in solar angles are small making intensesolar radiation. The possible reason may be monthly, sub-monthly time scale, temporal and spatial distribution of rainfall and temperature, which are determinant factors of production. Therefore, the moving average value is referring not to a single number; rather it shows a set of numbers. Mean annual minimum and maximum temperatures increased from 12.69 to 13.32 C and 26.43 to 26.91 C from 1981 to 2010, respectively. To determine the weighting the following general formula was employed (, Adapting to Climate Change: Natural Resource Management and Vulnerability Reduction, Background paper to the Task Force on Climate Change, Adaptation and Vulnerable Communities, Coping with drought among pastoral and agro-pastoral communities in eastern Ethiopia, Climate change adaptation strategies in Sub-Saharan Africa: foundations for the future, Climate Change-Realities, Impacts Over Ice Cap, Sea Level and Risks, Beyond the Famine: an Examination of the Issues Behind Famine in Ethiopia, International Institute for Relief and Development and Food for the Hungry International, Trend and variability of rainfall in Tigray, northern Ethiopia: analysis of meteorological data and farmers perception, Trending regional precipitation distribution and intensity: use of climatic indices, Trend analysis of rainfall and temperature data for India, Crop switching as a strategy for adapting to climate change, Annual rainfall and potential evapotranspiration in Ethiopia, Climate Change and Adaptation Options in Karamoja, Centennial rainfall variation in semi arid and tropical humid environments in the cardamom hill slopes, southern Western Ghats, India, Micro-level Analysis of Farmers Adaption to Climate Change in Southern Africa, International Food Policy Research Institute, Climate Change 2014: Synthesis Report. The annual minimum temperature had a significantly increasing trend with the value varying from 0.005 C/year and 1.90% in GIN station to 0.12 C/year and 52.40% in the DBS station. 2014). Water harvesting is particularly important for less rainy seasons and integrated water management, and will provide supplementary irrigation during deficits. The changes in the mean of hydrologic states and fluxes by the end of the 21st century are statistically robust, whereas changes in the variance are not found to be statistically significant. Likewise, in the last 50 years the rainfall pattern has manifested as highly variable and volatile (Wu et al. The average annual aerial rainfall of the Beressa watershed is 891 mm, with a coefficient variation of 30.6% and standard deviation of 227 mm. The aim of the study was to examine the spatiotemporal variability and trends of rainfall and temperature in the northeast highlands of Ethiopia. Principal Findings We found 12 studies that analysed the trend of climatic data and are relevant for the study of VBDs, 38 studies that dealt with the spatial and temporal distribution of disease vectors and disease transmission. The minimum and maximum temperature have increased by 0.8 and 1.1 C/year, respectively.. Previous Topic. Over the past decades, the minimum and maximum average temperature of Ethiopia have increased by about 0.25 and 0.1 C, respectively. This study assessed the historical (19832005) and future (20262100) rainfall, maximum temperature (Tmax), and minimum temperature (Tmin) trends of the Ziway Lake Basin (Ethiopia). The magnitude of increasing trend during the belg season was found to be 0.40 mm/year and 30.00% in DB station and a significantly decreasing trend was found to be 0.12 mm/year and 10.00 in GIN station. 33 days from submission to first decision on average. The results revealed that the magnitude of significantly increasing trend and variability was observed in mean annual rainfall for DB station (at 0.28 mm/year and 1.07%). Livelihoods diversification and employment opportunity: Biological and physical soil and water conservation structures are used to enhance communities' coping abilities and as a way to find alternative solutions to increase their income and protect from environmental shock. Time series of all MMA precipitation indices exhibit significant increasing trends over the 19012099 period. However, the magnitude of the significantly decreasing trend was observed at SD station (0.90 mm/year and 16.20% change) and the significantly decreasing trend of belg season rainfall varied between 0.12 mm/year and 10.00% at GIN station to a significantly increasing trend of 0.40 mm/year and 30.00% at DB station. In the years between 1981 and 1984, the annual total rainfall was far lower than the mean long-term rainfall. For instance, the variability, intensity and duration of temperature and rainfall affect crop production, especially for developing countries, particularly sub-Saharan countries in which the livelihoods of the population are dependent on subsistence and rainfed farming (Hulme et al. However, studies focusing on Zambia are still limited and future climate variability is poorly understood. Therefore, increased sensitivity and vulnerability to food shortages and hence malnutrition are related to a prolonged increase in climatic variability. Thus, the rainfall system in Ethiopia is characterized by spatial and temporalvariabilities.Rainfall in Ethiopia is the result is influenced by the position of Intertropical Convergence Zone(ITCZ). Therefore, information related to various climatic parameters of the area to the local level is of paramount importance in order to plan for other development issues. 2016). The area is characterized by diverse topographic conditions such as mountainous and dissected terrain with steep slopes. Here, the frequency and intensity of extreme precipitation over Zambia are analysed for the period 20212100 using an ensemble of 5 CMIP5 models from those recommended by the Intergovernmental Panel on Climate Change (IPCC). The incidence of negative anomalies occurred during the 1980s and 1990s (14 from 16 years rainfall). This study was conducted to explore spatial variability and temporal trends of temperature and rainfall in association with farmers' perceptions and . Trends are biased positive in the interior western US, so that strong RH decreases are changed to weak decreases, and weak decreases are changed to increases. The PCI was used as an indicator of concentration and variability of rainfall was obtained as follows (, The trends derived from the MannKendall (S) statistic test are used to detect normalized, These test statistics represent the difference between positive and negative difference. Annual and seasonal rainfall and temperature are influenced by the variability of the Intertropical Convergence Zone (ITCZ) which causes interannual rainfall variability over Ethiopia. In this study, we analyse global climate models in the Coupled Model Intercomparison Project phase 3 (CMIP3) and phase 5 (CMIP5) archives to investigate the qualitative aspects of change and trends in temperature and precipitation indices. Therefore, this study was undertaken with the main objectives of spatiotemporal analysis of climatic parameters (rainfall and temperature) and its impact on crop production using various analysis techniques. Spring (March, April and May)In this season, the noonday sun is shining directly on the equator while shifting north from south.The shift of the ITCZ, results in longer days and more direct solar radiation providing warmerweather for the northern world. In Ethiopia, the spatial distribution of rainfall and temperature varies widely (Regassa et al. **10% level of significant. This statistical test is a popular and important tool in detecting the trend used by many other scholars for related applications (Hirsch et al. The annual average temperature of the area is 19.7 C. Assessing the long-term spatiotemporal rainfall distribution pattern is the most significant component in the climate analysis of a given country, more specifically at the local and regional levels where the effect of climate change is worse. The High altitudesand the windward side experience such rainfall amount.ii. Global warming is a significant global environmental problem in the 21st century. Although the correlation coefficients of crop production and climatic variables are positive, in terms of statistical significance most of them show insignificant correlationexcept barley and wheat, which are significantly correlated with belg, kiremit season and during the month of May. 1.1. The analysis of vulnerability related to climate changes in Ethiopia implies that in the coming decades climate variability and volatility will threaten the social and economic order (damage to natural resources, agricultural productivity, water resources and ecosystems); therefore, the incidence and intensity of drought and famine occurrence is likely to increase. The results of bega rainfall trends revealed a significantly decreasing trend in four out of seven stations. How can we respond to the changing climate? Precipitation projections indicate increased mean precipitation with more frequent extreme rainfall during monsoon season in the EH region, and a wetter cold season in the WH region. Geological Processes and the Resulting Landforms of Ethiopia and the Horn, 2.5. The mean annual rainfall of the basin spatially varies from 417 to 1012 mm, with a noticeable temporal variation at a monthly time scale. However, after 1999 and onwards, recovery in the long-term average rainfall emerged higher than the average mean, except for the drier conditions in 2002 and 2013 which were lower than the long-term mean. During the winter season, the Redsea escarpments and some parts of the Afar region receive their main rain. For example, months from March to June in Ethiopiahave records of highest temperatures. Mainly, the regional topography and seasonal evolution of the large-scale circulation determined the geographical distribution of rainfall in Ethiopia (Diro et al., 2011).Global and regional change of the weather systems and the topographic variation together with the seasonal cycles are reason or major cause for the spatial variability of . 3. 2005). Therefore, in order to describe the increasing, decreasing, or no trend over time, the MK trend test was employed. Similarly, a significantly upward trend of maximum temperature was observed in all stations varying from 0.023 C/year and 4.00% in GIN station with a maximum value of 0.21 C/year and 37.60% in ENW station. The study watershed lies between 39 37E39 32E and 9 40N9 41N. Therefore, long-term analysis of climatic trends has been used to characterize the situations (Singh et al. Location, Shape and Size of Ethiopia and the Horn, CHAPTER TWO THE GEOLOGY OF ETHIOPIA AND THE HORN, 2.2. 5.3.1. The Mann-Kendall test results showed that the annual and seasonal rainfall trend was highly variable.

This report compiles information from a wide variety of data and information sources. Journal of Geophysical Research D: Atmospheres. Soil management: Soil erosion and degradation reduces crop productivity for traditional farming practices (particularly for mountainous area like the Beressa watershed), as erosion and degradation occurs at a higher rate than fertile soil formation. This process is repeated for the whole data sequence. The details of these seven stations are presented in Table2. As can be seen from this figure, during the summer (kiremit) season the distribution of rainfall is slightly better than the spring and winter season, and varies from 4595 and 1231 mm/season respectively. Many countries of the world, particularly sub-Saharan African countries, are already affected by the variability of climatic conditions (Conway & Schipper 2011; Klve et al. Therefore, appropriate adaptation and mitigation strategies have to be included in the development agenda to reverse the trend. Academia.edu no longer supports Internet Explorer. According to Griggs & Noguer (2002), Babel et al. It is vital to link physical data analysis with endogenous knowledge and practices of farmers to strengthen their adaptive capacity. For the kiremit (summer season), the main rainfall source is the northward oscillation of ITCZ and the development of high-pressure systems along the southern Atlantic as well as South Indian Oceans. The Hindu Kush-Himalayan (HKH) region epitomizes a geographic region where cryospheric processes coupled with hydrological regimes are under threat owing to a warming climate and shifts in climate extremes. Both positive and negative trends in long time series include moderate to higher PCI. 2017a, 2017b). The annual minimum and maximum rainfall is 698.5 and 1083.3 mm, respectively. Spatiotemporal Distribution of Rainfall Rainfall system in Ethiopia is characterized by complexities.

Before this period, the maximum temperature was 19.40 C and the minimum temperature was 6.20 C, with an average temperature of 12.80 C, while the time series maximum temperature has increased to 20.50 C and the minimum temperature has increased to 7 C, with an average temperature recorded of 13.75 C (Figure3). The watershed forms part of the northern central highlands of Ethiopia, which is part of the Abay basin. 2018 May 30;190(6):368. doi: 10.1007/s10661-018 . Following theposition of the overhead sun, the ITCZ shifts north and south of the equator. The exact position of the ITCZchanges over the course of the year, oscillating across the equator. Global climate models predict relative humidity (RH) in the western US will decrease at a rate of about 0.1 0.6 percentage points per decade, albeit with seasonal differences (most drying in spring and summer), geographical variability (greater declines in the interior), stronger reductions for greater anthropogenic radiative forcing, and notable spread among the models. The average rainfall inthe region varies from 1,400 to over 2,200 mm/year.iii. 2015; Wagesho & Yohannes 2016). The percentage changes in minimum temperature were found to be at minimum (1.90%) and maximum (52.40%) in GIN and DBS stations, respectively. Over the last three and a half decades, the total annual rainfall of the Beressa watershed has varied from 698.5 to 1,100 mm. 2015). Rock and Mineral Resources of Ethiopia, CHAPTER THREE THE TOPOGRAPHY OF ETHIOPIA AND THE HORN, 3.2. The magnitude of the linear trends is estimated using the Sen's slope estimator and Mann-Kendall's test is performed to check the statistical significance of the trends. This study investigates trends of climate extreme indices in the Komadugu-Yobe Basin (KYB) based on observed data of the period 1971-2017 as well as regional climate model (RCM) simulations for the historical period (1979-2005), the near future (2020-2050), and the far future (2060-2090).

The CMIP5 datasets were statistically downscaled by using the climate model data for hydrologic modeling (CMhyd) tool and bias corrected using the distribution mapping method available in the CMhyd tool. Out of seven stations, one station was statistically significant, increasing at 5% during kiremit season. Water Resources: Rivers, Lakes and Sub-Surface Water, 4.4. Autumn and Spring rainfall regionsThe region comprises areas receiving rain following the influence of southeasterly winds. Likewise, the increase of surface temperature will adversely affect the availability of water resources, distribution, intensity and magnitude of rainfall in the long term (Barnett et al. The problem is high in developing countries, particularly sub-Saharan countries in which the majority of the population live on rainfed agriculture. The impact of climate change is a global threat, and its effect is more pronounced in developing countries. In Ethiopia and elsewhere in the Horn,temperature shows seasonal variations. The available data for crop production (Q/ha) over 18 years (19972014) for the major crops such as barley, wheat, beans, peas, lentils and chickpeas were obtained from the district office of Agriculture and Central Statistical Authority.
