The Ethiopian section of the Great Rift Valley runs north-east to south-west, from Eritrea to northern Kenyaâs Lake Turkana, and much of the countryâs northern, western, central and southern areas are dominated by a series of highlands collectively known as the Ethiopian Plateau. The Ethiopian highlands are extremely heterogenous, with steep escarpments and deep valleys ().The highlands are known as âthe roof of Africaâ (in Africa the majority of land over 3000 m is found in Ethiopia) and reach 4533 m at the summit of Ras Dashen in the scenic world heritage Simien Mountains (Roberts et al., 2012).Most of the sub-Saharan Africa's Afroalpine ecosystem above 3200 â¦ Absolutely dated tree-ring records offer the potential to extend our understanding of climate into the pre-instr â¦ Historical droughts recorded in extended Juniperus procera ring-width chronologies from the Ethiopian Highlands Int J Biometeorol. In the Ethiopian Highlands, the climate is mild year-round, but rain punctuates the year with surprising regularity. Climate Risk Management, 25, pp. Sam will guide you through the magical heartland of Africa â travelling through Ethiopia you will enjoy the hospitality of incredible people and be enriched by the amazing history.Come with us and explore these unique dynamic environments on your Ethiopian travels. A. 1-14. The highlands of Ethiopia are home to the majority of the countryâs population, the cooler climate serving as a natural buffer against malaria transmission. The country is administratively divided into nine regions. Estimates suggest climate change may reduce Ethiopiaâs GDP up to 10 percent by 2045, primarily through impacts on â¦ In other words, the proportion of blue and green water can vary greatly depending on location in the diverse Ethiopian Highlands. The country has one of the most rugged and complex topographies in the continent. Recent citations Comparative performance of rural water supplies during drought D. J.

Even in the hottest months (March to May), average highs rarely exceed 77 degrees Fahrenheit (25 degrees Celsius). Which of the following physical features is located in the highlands climate zone on the map above? Farmers can usually count on a small spring rain, just enough to germinate seeds. Abstract. The late Pleistocene (20,000â12,000 14 C years BP) was cold and dry, with (1) low lake levels in the Rift Valley, (2) large debris fans on the flanks of Lake Abhé basin, and (3) the Blue Nile transporting coarse bedload. 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. We studied the combined effects of anthropogenic land-use change, past and future climate changes and mountain range isolation on the endemic Ethiopian Highlands long-eared bat, Plecotus balensis, an understudied bat that is restricted to the remnant natural high â¦ In the Ethiopian Highlands, the heterogeneity of the seasonal climate, topography, soil, land cover, and land management cause different hydrological responses at catchment and basin level. Then, R o values were estimated over the Ethiopian Highlands for current and future climates using both (1) observed time series of temperature data to identify the closest climate patterns among the 14 cities, and (2) annual temperatures in observed current and projected future climate (supplementary figure 8 and Methods). Dynamics of rural livelihoods and rainfall variability in Northern Ethiopian Highlands. New data now show that increasing temperatures over the past 35 years are eroding this buffer, allowing conditions more favorable for malaria to begin climbing into highland areas. Ethiopia is a landlocked country in East Africa occupying an area of 1,104,300 sq. Early season forecasts from the coupled forecast system (CFS) are steadier than European community medium range forecast (ECMWF). In July and August, a longer rainy period arrives to turn the hillsides bright green. Climate variability already negatively impacts livelihoods and this is likely to continue. Statistical methods were applied to gauge-interpolated, reanalysis, and satellite data to detect the LGP annual cycle. Lett. Studies by Debre Markos University show the area also faces severe land degradation due to human settlement, overgrazing, deforestation and unsustainable agricultural practices. Ethiopian Highlands on farmersâ climate perceptions and adaptations using group dis-cussions and PRA tools. recovery. Climate in Ethiopia Ethiopia has five climatic zones, characterized by altitude and temperature. Ethiopia is an ecologically diverse country; you can therefore expect several climate zones ranging from tropical savanna in the west to warm desert climate in the east. But this natural cycle has been disrupted in the Ethiopian Highlands, where much of the otherwise ample rainfall runs off the sloping hills sides, causing soil erosion and destruction. The Ethiopian Highlands home, Ethiopia, is the only country in Africa never to have been colonized. This study compares Climate Research Unit version 3 reference observations in the period 1980â2009 with Coupled Model Intercomparison Project Five (CMIP5)âsimulated climate patterns and trends over the Ethiopian highlands (7â14N, 36â40E) using the rcp6 scenario. Res.

In other words, the red and blue outlines show where new pockets of the Ethiopian Highlands became more malaria-friendly over the past 30 years. km. This study evaluates seasonal forecasts of rainfall and maximum temperature across the Ethiopian highlands from coupled ensemble models in the period 1981â2006, by comparison with gridded observational products (NMA + GPCC/CRU3). Of the nine regions, Africa RISING has been operating in the highlands of four (Amhara, Tigray, Oromia and Southern National Nationalities People (SNNP) regions). Most of the country is highland with many of its tourist destinations like Lalibela and Gondar are at an elevation above 2,000m (6,561ft). Alarmingly, this is projected to increase by a further 3.1°C by the 2060s. Drought is the single most destructive climate-related natural hazard in Ethiopia. From 1979 to 2005, the Ethiopian highlands saw a warming of 0.70 to 1.17° F (0.39 to 0.65° C). The climate of the Choke Mountain watershed in the Upper Blue Nile Highlands is changing as the planet warms. This paper presents a review of climate variability in the northeast Ethiopian Highlands, particularly Wollo and Tigray, during the last 10000 years (the Holocene) and an analysis of rainfall variability during the historical period. Welcome to Ethiopian Adventure Tours! The highlands of Ethiopia are home to the majority of the countryâs population, the cooler climate serving as a natural buffer against malaria transmission. We have compared hydro-climate change in the 20th century and projections in the 21st century , particularly with regard to the seasonal onset and cessation of conditions favoring crop phenology in the NW Ethiopian highlands. After 7,000 years of agriculture, the land is tiring out. We related these to climate data spanning 30 years (1981 to 2010), consisting of daily minimum temperature, maximum temperature and precipita-tion, modelled for the four communities using global databases and regional meteoro-logical data. Throughout the year, temperatures drop quickly once the sun goes down, and frosty mornings are common. For centuries, Ethiopian farmers have used the traditional Maresha plow to till their lands. The study has aimed to reveal the livelihood dynamics of rural households in Ethiopia and their association with rainfall conditions and household socio-economic characteristics.
