Because of the rainfall-dependent farming practice, farmers are always worried about the duration and intensity of rainfall. 2005; Batisani & Yarnal 2010; Randell & Gray 2016). 2011; Pachauri et al. Among 38 studies, only eight studies assessed the association of VBDs with climatic variables. This process is repeated for the whole data sequence. 2015 . Southern part ofEthiopia receives highest records of temperature in autumn and spring following the relativeshift of the sun; whereas in the northern part of the country, summer season is characterized byhigher temperature.It has to be noted that certain seasons should have special considerations. Air temperature estimation using remote sensing satellite provides a new way of conducting studies in the field of climate change study. In view of this, the incidence of food shortage is a common occurrence. Months in summer gainhighest rainfall whereas the winter months receive the reduced amount. Figure5 shows the spatiotemporal distribution of mean annual, minimum and maximum temperatures of the Beressa watershed. Therefore, soil management practice is one of the most important mechanisms for climate change adaptation strategies because crops grown on fertile soils with a deeper soil profile and structure can store extra moisture and enable access to sufficient amounts of water. It could also increase the probability of large fires in the northern and central US Rocky Mountains by 13 to 60 %. However, studies focusing on Zambia are still limited and future climate variability is poorly understood. Five years moving average rainfall (19802014). Spatiotemporal Distribution of Rainfall Rainfall system in Ethiopia is characterized by complexities. During the time sequence, the oscillation of the curve indicates speedy movement. Specifically, we examine and evaluate multi-model, multi-scenario climate change projections and seven extreme temperature and precipitation indices over the eastern Himalaya (EH) and western Himalaya-Karakoram (WH) regions for the 21st century. Therefore, community-based soil and water conservation practices help the communities to diversify their livelihood activities. .

Additionally, studies of rainfall and temperature variations in larger areas would in general be of little use for local level agricultural production (Gebre et al. Our analyses demonstrate that there will be an increase in precipitation intensity and a decrease in frequency over Zambia from the middle of the 21st century. In the tropics, the daily range of temperature is higher and theannual range is small, whereas the reverse is true in the temperate latitudes. The study watershed lies between 39 37E39 32E and 9 40N9 41N. Fine-scale hydrological simulations driven by the global model results should reproduce these trends. Overall, the five years moving average trend of average annual temperature of the study watershed is increasing by about 0.95 C. In Ethiopia, as in allplaces in the tropics, the air is frost free and changes in solar angles are small making intensesolar radiation. Seasonal analysis of rainfall obtained from MK test statistic results are presented in Table3. 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. 2013; Pingale et al. Enter the email address you signed up with and we'll email you a reset link. The CHIRPS was developed by the Climate Hazards Group (CHG) at the University of California (Knapp et al. Water Resources: Rivers, Lakes and Sub-Surface Water, 4.4. The trend of increasing maximum temperature is stronger than the minimum temperature. To avoid the generalities inherent in regional projections, projections focussing on an individual country are necessary. Discuss spatiotemporal distribution of temperature and rainfall in Ethiopia. Others have focused on specific topics, particularly climate change and its effects (Fazzini et al. Within this regional context, temperature data are modeled to assess its projected variation impacts on rainfall depth due to climate change. The northeasterly winds crossing the Red Seacarry very little moisture and supplies rain only to the Afar lowlands and the Red Sea coastalareas.iv. Winter (December, January and February)In winter, the overhead sun is far south of equator. Therefore, in order to know the yields, annual rainfall is less important for prediction. Therefore, depending on the historical trend of rainfall variability and prolonged temperature increase, appropriate coping and adaptation strategies need to be encouraged. 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). Rainfall Regions of EthiopiaBased on rainfall distribution, both in space and time, four rainfall regions can be identifiedin Ethiopia and the Horn. According to Griggs & Noguer (2002), Babel et al. 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. 2010; Simane et al. Data and Methods 3.1. Afar and parts ofEritrean coastal areas experience rainfall in this period. The Geological Time Scale and Age Dating Techniques, 2.4. Abstract: Since China announced its goal of becoming carbon-neutral by 2060, carbon neutrality has become a major target in the development of China's urban agglomerations. In general, these future projections point towards increases in summertime temperatures and modifications in precipitation across both regions. In Ethiopia, traveling from one area to another can mean shifting from 60 degrees Fahrenheit (15 degrees Celsius) to 95 degrees Fahrenheit (35 degrees Celsius) in a matter of hours. According to a report made by the Intergovernmental Panel on Climate Change (Parry 2007; Pachauri et al. Fluctuating productivity and hence food insecurity for the area is due to long-term variability in the annual and seasonal rainfall. Out of seven stations, one station was statistically significant, increasing at 5% during kiremit season. Correlation between crop production, and rainfall and temperature (19972014). Additionally, serial correlation was tested. 2001; Kurukulasuriya & Mendelsohn 2008). 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. Therefore, clear information about the annual and seasonal rainfall distribution is highly important for policy planners and local users. Rainfall and temperature trends detection is vital for water resources management and decision support systems in agro-hydrology. Extreme precipitation and streamflow events are expected to become more frequent. 2014). 3.1 Spatial distribution of rainfall in Ethiopia. Elements and Controls of Weather and Climate, 5.3. The Mann-Kendall test results showed that the annual and seasonal rainfall trend was highly variable. 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 moving average is possibly acquired by considering the initial subset average.

The present results are in agreement with Parry (2007), who stated that due to a prolonged increase in the emission of gases through human activities and expansion of industry, the surface temperature has increased by about 1 C. 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. Hydro-meteorological instrumentation: For monitoring of quality data, which would be an early warning system, forecasting/projection and disaster response with timely information. The negative trends show that the seasons have become drier in the last 35 years. **10% level of significant. During thisseason, Ethiopia and the Horn come under the influence of the Equatorial Westerlies (Guineamonsoon) and Easterlies.Hence, the Guinea monsoon and the South easterly winds areresponsible for the rain in this season.ii. During these seasons, rainfall is more highly variable than the main rainy season of the area. Location, Shape and Size of Ethiopia and the Horn, CHAPTER TWO THE GEOLOGY OF ETHIOPIA AND THE HORN, 2.2. The guidelines for interpretation are presented in Table1. 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. Annual and seasonal rainfall and temperature are influenced by the variability of the Intertropical Convergence Zone (ITCZ) which causes interannual rainfall variability over Ethiopia. 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. During this period,the Northeast Trade Winds carrying non-moisture-laden dominates the region. 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). Ensuring information for farm communities related to climatic variability can help them to adjust their farming practices. Density distribution plots of observed climate indices for meteorological stations and gridded indices are also analysed, which indicate significant negative trends in the annual number of frost days and significant increasing trends in warm nights in the EH region over the 19602000 period. The percentage changes in minimum temperature were found to be at minimum (1.90%) and maximum (52.40%) in GIN and DBS stations, respectively. 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. Therefore, the projected rainfall and temperature have been corrected for biases by using empirical Quantile Mapping. Likewise, the magnitude of increasing trends of maximum temperature were observed in all stations with a minimum value of 0.023 C/year in GIN station and a maximum value of 0.21 C/year in ENW station. Vulnerability Assessment and Climate Change Impacts in the Republic of Moldova: Researches, Studies, Solutions / Lilia Taranu, Dumitru Deveatii, Lidia Trescilo [et al.] 2015). The rate and variability of increasing temperature have dramatically increased, making it more difficult for local communities to foresee the intensity and magnitude of temperature even for the next few years. This The magnitude of the significantly increasing trend of mean annual rainfall of 0.28 mm/year and 1.07% (DB station) was recorded, whereas a significantly decreasing trend of mean annual rainfall was observed with the values of 8.62 mm/year and 27.88% (HG station). 2016). In the rainfall distribution during belg and kiremit it was found that there was a moderate concentration of precipitation throughout the seasons, which shows that there is no uniform distribution, whereas during the bega season a significant change in the PCI was shown, thus the concentration of precipitation is increasing and rainfall has become more erratic. Spatiotemporal Distribution of RainfallRainfall system in Ethiopia is characterized by complexities. Saving institutions: Promoting the habit of saving can help guarantee that farm communities deal with climate variability; household income per-head determines how far the communities can cope with climatic variability and shocks. The rainfall and temperature daily records over 35 years (19802014) for the Beressa watershed were obtained from the National Meteorological Service Agency of Ethiopia from seven stations; hence rainfall on a monthly, seasonal and annual basis were derived from the daily data. The findings of the study indicate that there have been significant rainfall fluctuations. 2013; Muhire & Ahmed 2015). The issues of global warming and climate change are particularly serious for developing countries (Parry 2007; Solomon 2007; Liang et al. 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. As already explained. The average rainfallvaries from less than 500 to 1,000 mm.iv. For example, months from March to June in Ethiopiahave records of highest temperatures. 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. Conversely, low temperatures are recorded fromNovember to February.It is not easy to observe distinct variation in temperature between seasons as the sun is alwayshigh in the tropics. Despite the importance of soil moisture, studies on soil moisture characteristics in Ethiopia are less documented. The researches and analysis in this study indicates that, while climate change is likely to pose serious threats to development in the RM, it also has the potential to bring opportunities. Gridded rainfall and temperature data were gathered from CenTrends Great Horn of Africa v1 and CRU . The MK test, Sen's slope and precipitation concentration index (PCI) were applied. s u m m a r y Due to global warming the climate of central Chile is expected to experience dramatic changes in the 21st century including declining precipitation, earlier streamflow peaks, and a greater proportion of precipitation falling as rain. 5.3.2. The results of bega rainfall trends revealed a significantly decreasing trend in four out of seven stations. During the winter season, the Redsea escarpments and some parts of the Afar region receive their main rain. Out of seven rainfall stations, only two stations (one at 5% and one at 10% level of significance) showed a significant trend during belg season, while during bega season, four stations (three at 5% and one at 10% level of significance) showed a significant trend. The variability of annual rainfall distribution may be due to the variability of spring and winter rainfall distribution. For more than 70% of the world's population, the primary source of their livelihood has originated from weather sensitive agriculture (Suarez et al. In kiremit season, rain is essential but it extends to the bega season during the harvesting stage. The period from March to May, as often happens in Ethiopia, is the warmest of the year, albeit by a few degrees. Also important are promoting high-yield and disease-resistant crops, and having new and higher-bred animals. However, there is a slight temperature increase in summer. Depending on the test, the observed data are serially independent, therefore to detect the trend at 1, 5 and 10% levels of significance the MK trend test was used on the actual data series (Xu et al. Finally, Pearson correlation analysis between climatic variables and crop production was analysed. During the belg (small rainy) season the subdivision indicates a slightly increasing rainfall trend and the bega season (dry season) shows a negative trend, as already presented in Figure2. 2017a, 2017b). 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. This study assessed the historical (1983-2005) and future (2026-2100) rainfall, maximum temperature (Tmax), and minimum temperature (Tmin) trends of the Ziway Lake Basin (Ethiopia). 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. 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. In this study, the spatiotemporal variability of Ethiopian soil moisture (SM) has been characterized, and its local and remote influential driving factors are investigated . Mixed crop-livestock is the production system of the area and is perhaps the only source of livelihood for the majority of the population. 2014; Mondal et al. 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. The time series of five years moving average minimum and maximum temperature was analysed for the period 19802014. We used 12-member ensembles of General Circulation Models (GCMs) from the Coupled Model Intercomparison Project Phase 3 (CMIP3) and Phase 5 (CMIP5) to evaluate climate-attributed changes in the hydrology of the Mataquito river basin in central Chile, South America. 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. The results of correlation analysis between crop production and climatic variables (rainfall and temperature) during the period 19972014 are shown in Table5. Although there is a positive trend in the annual total rainfall, the number of consecutive wet (dry) days decreases (increases). temperature is high during the daytime in some places, and is considerably reduced at nightresulting maximum difference in the daily range.But in the case of monthly averages, variation is minimal and the annual range of temperature issmall. However, in the belg season during the period 19802014 the five years' average moving annual and seasonal rainfall was considerably variable. pieces of evidence indicated that a detailed study of the spatial and temporal characteristics of rainfall and temperature are very important for agricultural/urban planning (mehmet, 2015 ), flood frequency analysis, water resources assessments, assessing and understanding climate change impacts, and other environmental assessments (alemu, 2019; Search for other works by this author on: Journal of Water and Climate Change (2019) 10 (4): 799817. Multi-model average (MMA) projections additionally indicate continued trends towards more extreme conditions consistent with a warmer, wetter climate. Sorry, preview is currently unavailable. Figure 1. Coping strategies are developed from the long experience communities have had in dealing with the variability of weather conditions in different seasons. 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. The minimum and maximum temperature have increased by 0.8 and 1.1 C/year, respectively.. The long-term rainfall trend was assessed monthly, seasonally i.e. The wetness of this region is particularly due to the prepotency of moist aircurrents of equatorial Westerlies called the Guinea Monsoons. contribution of working group I to the third assessment report of the intergovernmental panel on climate change, Techniques of trend analysis for monthly water quality data, Global warming and African climate change: a reassessment, Long-term variations and trends in precipitation in Finland, Theory and practice in assessing vulnerability to climate change and facilitating adaptation, The value of large-scale climate variables in climate change assessment: the case of Botswana's rainfall, Precipitation climatology over India: validation with observations and reanalysis datasets and spatial trends, Climate change impacts on groundwater and dependent ecosystems, Downscaled climate change projections with uncertainty assessment over India using a high resolution multi-model approach, Precipitation variability in Northeast China from 1961 to 2008, Adapting cropping systems to climate change in Nepal: a cross-regional study of farmers perception and practices, The UNDP Climate Change Country Profiles: improving the accessibility of observed and projected climate information for studies of climate change in developing countries, Trends in daily observed temperature and precipitation extremes over three Ethiopian eco-environments, http://agris.fao.org/agris-search/search.do?recordID=ET2009000029, Analyses of land use and land cover change dynamics using GIS and remote sensing during 1984 and 2015 in the Beressa Watershed Northern Central Highland of Ethiopia, Contrasting climate variability and meteorological drought with perceived drought and climate change in northern Ethiopia, Using the seasonal and temporal precipitation concentration index for characterizing the monthly rainfall distribution in Spain, Spatial and temporal analysis of rainfall and temperature trend of India, Spatio-temporal trend analysis of precipitation data over Rwanda, Monthly precipitation distribution: a comparative index, Trend analysis in Turkish precipitation data, Spatial and temporal trends of mean and extreme rainfall and temperature for the 33 urban centers of the arid and semi-arid state of Rajasthan, India, Trend analysis of climatic variables in an arid and semi-arid region of the Ajmer District, Rajasthan, India, Climate variability and educational attainment: evidence from rural Ethiopia, An assessment of the potential impact of climate change on flood risk in Mumbai, Assessment of statistical characteristics of point rainfall in the Onkaparinga catchment in South Australia, Assessment of trends in point rainfall using Continuous Wavelet Transforms, Rainfall variability in the Ethiopian and Eritrean highlands and its links with the Southern Oscillation Index, Recent changes in rainfall and rainy days in Ethiopia, Building climate resilience in the Blue Nile/Abay Highlands: a framework for action, Changes in rainfall and relative humidity in river basins in northwest and central India, An investigation into observational characteristics of rainfall and temperature in Central Northeast India a historical perspective 18892008, Long-term historic changes in climatic variables of Betwa Basin, India, Modeling runoffsediment response to land use/land cover changes using integrated GIS and SWAT model in the Beressa watershed, Household level tree planting and its implication for environmental conservation in the Beressa Watershed of Ethiopia, Spatiotemporal analysis of precipitation trends under climate change in the upper reach of Mekong River basin, Long-term trend analysis for major climate variables in the Yellow River basin, Spatial analysis of monthly and annual precipitation trends in Turkey, Power of the MannKendall and Spearman's rho tests for detecting monotonic trends in hydrological series, Canadian streamflow trend detection: impacts of serial and cross-correlation, Analysis of precipitation characteristics during 19572012 in the semi-arid Loess Plateau, China, Uniform distribution of precipitation (lLow concentration), Moderate distribution of precipitation (moderate concentration), Strong irregularity of precipitation distribution, Republic Export Building,Units 1.04 & 1.05.
