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. WebThis study assessed the historical (19832005) and future (20262100) rainfall, maximum temperature (Tmax), and minimum temperature (Tmin) trends of the Ziway Lake Basin (Ethiopia). During the winter season, the Redsea escarpments and some parts of the Afar region receive their main rain. Both duration and amount ofrainfall decreases as we move from southwest to north and eastwards. discuss spatiotemporal distribution of temperature and rainfall in ethiopia. Afar and parts ofEritrean coastal areas experience rainfall in this period.
Daspal Technology Services. Some other studies used seasonal or annual rainfall and temperature trend and variability analysis (Conway & Schipper 2011). The temperature and rainfall of this category is highly suitable for majority of crops grown in Ethiopia. Sponsored Schools. 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. Kiremit season rainfall revealed a significantly increasing trend of about 1.62 mm/year and 31.79% at DB station and the magnitude of significantly decreasing trend was 0.90 mm/year and 16.20% at SD station. All crop production shows considerably high correlation with maximum temperature and stronger correlation with barley, while in the case of minimum temperature, poor correlation was observed for all crops. The region is divided in to dry and wet summer rainfall regions.Hence, the wet corresponds to the area having rainfall of 1,000 mm or more. Throughout the year, 1,160 mm (46 in) of rain fall, with a maximum from June to September, which is The belg (spring) season manifested by a short rainy season covers three months (MarchMay) and the dry season known as bega (winter) runs from October to February. In kiremit season, rain is essential but it extends to the bega season during the harvesting stage. Throughout the year, 1,160 mm (46 in) of rain fall, with a maximum from June to September, which is
2014). This development mainly happens in July in Ethiopia and the Horn causingvariability and seasonality.The ITCZ shifts towards south of equator (Tropic of Capricorn) in January. Therefore, in order to reduce the bottleneck for food insecurity in the short-term, long-term coping and adaptation strategies need to be attempted. 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. The details of these stations have already been presented in Table2. The results from the coefficient of variations shown in Table2 revealed that in comparison with the kiremit rainfall season, during the bega and belg seasons rainfall varies considerably more. Several factors are known to regulate Ethiopia's climate. All year-round rainfall regionIt has many rainy days than any part of the country. Even though the rainfall indicates seasonal and inter-annual variability, the area is characterized by a bimodal rainfall regime, with maximum rainfall concentration during kiremit (summer) season, which extends from June to September. Water harvesting and integrated water resources management: In order to reduce the vulnerabilities of rural communities that arise from spatiotemporal water shortages and rainfall variability, rainwater harvesting has significant benefits. This is particularly the case for the local community, whose economy is susceptible to variability and the erratic nature of rainfall and water shortage; recurrent drought is a common phenomenon. However, some parts of thecountry enjoy a temperate climate. 2015; Wagesho & Yohannes 2016). The production of beans was below 18-year mean in nine years out of 18 years production periods, as indicated in Table5, which accounts for 50% of the total bean production; while in respect of kiremit rainfall pea, chickpea, and lentil production (50, 50 and 55.5% respectively) were below the 18-year mean. After visual identification of the outliers, each of the values was obtained using a normal ratio technique. Winter (December, January and February)In winter, the overhead sun is far south of equator. The MannKendall test results showed that the annual and seasonal rainfall trend was highly variable. For this purpose, SST and rainfall data were used to study a wide range of inhomogeneous areas in Ethiopia with uneven distribution of rainfall for both summer (1951–2015) and spring The results of bega rainfall trends revealed a significantly decreasing trend in four out of seven stations. The issues of global warming and climate change are particularly serious for developing countries (Parry 2007; Solomon 2007; Liang 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.

Reasons that make CRM systems important: Why Zoho CRM is in the hype now. Starting a new venture? Based on these observations, the rainfall pattern and distribution of the area could be classified as irregular and erratic distribution. In contrast to the kiremit season, the five years' moving average annual rainfall of the bega season during the period 19802014 was highly variable. 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. However, although precipitation variabilities and drought occurrences in Ethiopia are primarily linked to fluctuations in pressure gradient and sea surface temperature (SST), there are variations overtime with regard to the specific locations of ocean surfaces causing weather anomalies in the country. The area is characterized by diverse topographic conditions such as mountainous and dissected terrain with steep slopes. For instance, unlikeother parts of Ethiopia, the southern and southwestern highlands experience reducedtemperature. 2014; Kishore et al. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. In this season, the effect of the northeast trade wind is very muchreduced. They are limited to the lowlands in the peripheries.Away from the peripheries the land begins to rise gradually and considerably, culminating inpeaks in various parts of the country. 2014). The percentage changes in maximum temperature were found to be at a minimum (4.00%) and maximum (37.60%) in the GIN and ENW High correlation existed between crops and rainfall, and temperature was found to have a direct impact on the communities, particularly rain-fed dependants.

Ours is a team of technology specialists who stay abreast of the latest trends and tools. The variation inthe amount of solar radiation received daily is small throughout the year. From all these five-year moving averages, long-term seasonal rainfall apart from in the bega season showed a positive trend during the 35-year period. Sponsored Schools. 2016). The present study aimed to undertake spatiotemporal analysis of seasonal and annual rainfall and temperature and its implications. For this purpose, SST and rainfall data were used to study a wide range of inhomogeneous areas in Ethiopia with uneven distribution of rainfall for both summer (1951–2015) and spring Therefore, community-based soil and water conservation practices help the communities to diversify their livelihood activities. The magnitude of the decreasing trend was found to be 0.06 mm/year and 7.50% in GIN station, 0.05 mm/year and 8.80% at SD station, 0.11 mm/year and 12.70% at HG station, 0.13 mm/year and 29.00% change at SH station, 0.19 mm/year and 53.00% at DB station, 0.19 mm/year and 35.00% and 0.20 mm/year and 56.40% change at DBS station. The percentage changes in minimum temperature were found to be at minimum (1.90%) and maximum (52.40%) in GIN and DBS stations, respectively. Crop production showed high correlation with belg and kiremit rainfall; only annual rainfall and barley crops showed stronger correlation. The correlation between rainfall during the months of MaySeptember and crops has a positive relationship, except in the cases of beans, peas and chickpeas, which are inversely correlated with rainfall during the month of June. ochsner obgyn residents // discuss spatiotemporal distribution of temperature and rainfall in ethiopia Here are the average temperatures. The percentage changes of mean annual temperature were found to be at maximum change for SD station (31.30%) and at minimum change for DB station (7.60%). Finally, Pearson correlation analysis between climatic variables and crop production was analysed. Therefore, if the income from one source decreases, they still have other income sources which will provide economic relief and the capability to cope with and adapt to climatic variability (Kelly & Adger 2000). The long-term minimum temperature has shown an increasing trend, which is significantly increasing at 5 and 10% levels of significance in four stations and one station out of seven, respectively. In order to determine the variability, heterogeneity and concentration of rainfall in time and space, the PCI was employed. Five years moving average temperature (19802014). For most developing countries of the world, agriculture is the basis of the economy. (2011), adaptation strategies are an important mechanism for managing climatic change and variability. WebEthiopia. Seasonal analysis of rainfall obtained from MK test statistic results are presented in Table3. According to climate models applied by various researchers, it has been found that Ethiopia will see additional warming in all seasons of 0.72.3 C by the 2020s and 1.42.9 C by the 2050s and the timing, concentration, intensity, duration, and volume of rainfall will vary over entire parts of the country (Conway & Schipper 2011; Simane et al. According to Griggs & Noguer (2002), Babel et al. 2010). The northeasterly winds crossing the Red Seacarry very little moisture and supplies rain only to the Afar lowlands and the Red Sea coastalareas.iv. This study involves the observation of climatic variables, i.e. Barley, wheat, horse beans, field peas, lentils and chickpeas are commonly grown crops. It is a rainfall region in the southwestern partof the country. (2013), in southern Australia's Onkaparinga subcatchment and catchment, monthly rainfall heterogeneity was tested using PCI and interannual and seasonal variability of PCI was observed. 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. Winter rainfall regionThis rainfall region receives rain from the northeasterly winds. From Figure3, it is confirmed that the maximum temperature has continuously increased by about 1.10 C, whereas the minimum temperature has increased by about 0.70 C. It is the second largest zone covering more than 26% of the landmass of Ethiopia. During this period,the Northeast Trade Winds carrying non-moisture-laden dominates the region. 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. discuss spatiotemporal distribution of temperature and rainfall in ethiopia happy to be a part of the team synonym 2023 "Moroni's America" - The North Therefore, the moving average value is referring not to a single number; rather it shows a set of numbers. Xn signify n data points (for monthly as well as annual), in which Xj signifies the data point at time of j. Spatiotemporal Distribution of TemperatureAltitude is an important element in determining temperature of Ethiopia and the Horn. The calculated PCI for seasonal as well as inter-annual rainfall distribution for the spatiotemporal time series is shown in Table2. Therefore, in order to know the yields, annual rainfall is less important for prediction. Some of the studies conducted are based on areal averages of spatial climatic variability (Seleshi & Demaree 1995; Osman & Sauerborn 2001). Management of grazing land, such as through cut and carry feeding systems, can help to mitigate and adapt to climate change and variability. 2002; Suryavanshi et al. The variation in the amount of solar radiation received daily is small throughout the year. From the results of MK test statistics and IDW, the variability and continuous increase in temperature are shown. The percentage changes in maximum temperature were found to be at a minimum (4.00%) and maximum (37.60%) in the GIN and ENW In the years between 1981 and 1984, the annual total rainfall was far lower than the mean long-term rainfall. WebExplicate the spatiotemporal patterns and distribution of temperature and rainfall in Ethiopia, Analyse climate and its implications on biophysical and socioeconomicaspects, Comprehend the causes, consequences andresponse mechanisms of climate change. 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. Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. WebThe period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees.

Reasons that make CRM systems important: Why Zoho CRM is in the hype now. Starting a new venture? Based on these observations, the rainfall pattern and distribution of the area could be classified as irregular and erratic distribution. In contrast to the kiremit season, the five years' moving average annual rainfall of the bega season during the period 19802014 was highly variable. 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. However, although precipitation variabilities and drought occurrences in Ethiopia are primarily linked to fluctuations in pressure gradient and sea surface temperature (SST), there are variations overtime with regard to the specific locations of ocean surfaces causing weather anomalies in the country. The area is characterized by diverse topographic conditions such as mountainous and dissected terrain with steep slopes. For instance, unlikeother parts of Ethiopia, the southern and southwestern highlands experience reducedtemperature. 2014; Kishore et al. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. In this season, the effect of the northeast trade wind is very muchreduced. They are limited to the lowlands in the peripheries.Away from the peripheries the land begins to rise gradually and considerably, culminating inpeaks in various parts of the country. 2014). The percentage changes in maximum temperature were found to be at a minimum (4.00%) and maximum (37.60%) in the GIN and ENW High correlation existed between crops and rainfall, and temperature was found to have a direct impact on the communities, particularly rain-fed dependants.

Ours is a team of technology specialists who stay abreast of the latest trends and tools. The variation inthe amount of solar radiation received daily is small throughout the year. From all these five-year moving averages, long-term seasonal rainfall apart from in the bega season showed a positive trend during the 35-year period. Sponsored Schools. 2016). The present study aimed to undertake spatiotemporal analysis of seasonal and annual rainfall and temperature and its implications. For this purpose, SST and rainfall data were used to study a wide range of inhomogeneous areas in Ethiopia with uneven distribution of rainfall for both summer (1951–2015) and spring Therefore, community-based soil and water conservation practices help the communities to diversify their livelihood activities. The magnitude of the decreasing trend was found to be 0.06 mm/year and 7.50% in GIN station, 0.05 mm/year and 8.80% at SD station, 0.11 mm/year and 12.70% at HG station, 0.13 mm/year and 29.00% change at SH station, 0.19 mm/year and 53.00% at DB station, 0.19 mm/year and 35.00% and 0.20 mm/year and 56.40% change at DBS station. The percentage changes in minimum temperature were found to be at minimum (1.90%) and maximum (52.40%) in GIN and DBS stations, respectively. Crop production showed high correlation with belg and kiremit rainfall; only annual rainfall and barley crops showed stronger correlation. The correlation between rainfall during the months of MaySeptember and crops has a positive relationship, except in the cases of beans, peas and chickpeas, which are inversely correlated with rainfall during the month of June. ochsner obgyn residents // discuss spatiotemporal distribution of temperature and rainfall in ethiopia Here are the average temperatures. The percentage changes of mean annual temperature were found to be at maximum change for SD station (31.30%) and at minimum change for DB station (7.60%). Finally, Pearson correlation analysis between climatic variables and crop production was analysed. Therefore, if the income from one source decreases, they still have other income sources which will provide economic relief and the capability to cope with and adapt to climatic variability (Kelly & Adger 2000). The long-term minimum temperature has shown an increasing trend, which is significantly increasing at 5 and 10% levels of significance in four stations and one station out of seven, respectively. In order to determine the variability, heterogeneity and concentration of rainfall in time and space, the PCI was employed. Five years moving average temperature (19802014). For most developing countries of the world, agriculture is the basis of the economy. (2011), adaptation strategies are an important mechanism for managing climatic change and variability. WebEthiopia. Seasonal analysis of rainfall obtained from MK test statistic results are presented in Table3. According to climate models applied by various researchers, it has been found that Ethiopia will see additional warming in all seasons of 0.72.3 C by the 2020s and 1.42.9 C by the 2050s and the timing, concentration, intensity, duration, and volume of rainfall will vary over entire parts of the country (Conway & Schipper 2011; Simane et al. According to Griggs & Noguer (2002), Babel et al. 2010). The northeasterly winds crossing the Red Seacarry very little moisture and supplies rain only to the Afar lowlands and the Red Sea coastalareas.iv. This study involves the observation of climatic variables, i.e. Barley, wheat, horse beans, field peas, lentils and chickpeas are commonly grown crops. It is a rainfall region in the southwestern partof the country. (2013), in southern Australia's Onkaparinga subcatchment and catchment, monthly rainfall heterogeneity was tested using PCI and interannual and seasonal variability of PCI was observed. 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. Winter rainfall regionThis rainfall region receives rain from the northeasterly winds. From Figure3, it is confirmed that the maximum temperature has continuously increased by about 1.10 C, whereas the minimum temperature has increased by about 0.70 C. It is the second largest zone covering more than 26% of the landmass of Ethiopia. During this period,the Northeast Trade Winds carrying non-moisture-laden dominates the region. 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. discuss spatiotemporal distribution of temperature and rainfall in ethiopia happy to be a part of the team synonym 2023 "Moroni's America" - The North Therefore, the moving average value is referring not to a single number; rather it shows a set of numbers. Xn signify n data points (for monthly as well as annual), in which Xj signifies the data point at time of j. Spatiotemporal Distribution of TemperatureAltitude is an important element in determining temperature of Ethiopia and the Horn. The calculated PCI for seasonal as well as inter-annual rainfall distribution for the spatiotemporal time series is shown in Table2. Therefore, in order to know the yields, annual rainfall is less important for prediction. Some of the studies conducted are based on areal averages of spatial climatic variability (Seleshi & Demaree 1995; Osman & Sauerborn 2001). Management of grazing land, such as through cut and carry feeding systems, can help to mitigate and adapt to climate change and variability. 2002; Suryavanshi et al. The variation in the amount of solar radiation received daily is small throughout the year. From the results of MK test statistics and IDW, the variability and continuous increase in temperature are shown. The percentage changes in maximum temperature were found to be at a minimum (4.00%) and maximum (37.60%) in the GIN and ENW In the years between 1981 and 1984, the annual total rainfall was far lower than the mean long-term rainfall. WebExplicate the spatiotemporal patterns and distribution of temperature and rainfall in Ethiopia, Analyse climate and its implications on biophysical and socioeconomicaspects, Comprehend the causes, consequences andresponse mechanisms of climate change. 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. Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. WebThe period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees.
