The first type is composed of euritic nitosols and andosols and is found on portions of the Western and Eastern highlands. Source: Bryan et al. The warming trends in the maximum and minimum temperatures for Basona Werana and Efratana Gidim, respectively, are statistically significant at p = .05 and p = .01 levels. Gorilla slaughter, conflict, deforestation and demand for charcoal in Rwanda and eastern DRC 53 Box 4. If you do not receive an email within 10 minutes, your email address may not be registered, Trends in annual, seasonal and maximum 30-day extreme rainfall over Ethiopia are investigated using 0.5° latitude × 0.5° longitude gridded monthly precipitation data. Minimum temperatures significantly increased in northern, central, southern and southeastern parts of the Basin in all seasons. aegypti were reported in a recent study from central Nepal . [24] P. A. Bostan, Z. Akyürek, “Spatio-temporal analysis of precipitation and temperature distribution over Turkey”, The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol. According to a publication by Global Trees Campaign entitled Red List of Endemic Trees and Shrubs of Ethiopia and Eritrea;six species were attributed as threatened, among those were the following: The monthly rainfall data are for 132 points of 10 × 10 km grids reconstructed from weather stations and meteorological satellite observations, which cover the period between 1983 and 2013. Farmers’ perceptions of average temperature and rainfall changes in Ethiopia over the last 20 years from 2004/2005 (n = 1000). 3. Climatology. 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. All seasons except spring season exhibited similar statistically non‐significant trends. Woldeamlak Bewket is a professor of Environmental Studies at Addis Ababa University, Ethiopia. Even in the hottest months (March to May), average highs rarely exceed 77 degrees Fahrenheit (25 degrees Celsius). The paper has benefited from useful comments and suggestions by two anonymous referees and the editor to whom the authors are very grateful. The spatial coherence of annual rainfall among contiguous rainfall grid points is also assessed for possible spatial similarity across the country. Int J Environ Sci Nat Res. Linear regression is used to each of the 132 grid points to detect changes or trends in rainfall, maximum and minimum temperatures and the statistical significance of the trends is determined by the F-distribution test. Recent spatiotemporal temperature and rainfall variability and trends over the Upper Blue Nile River Basin, Ethiopia June 2014 International Journal of Climatology 34(7) The data were obtained from the National Meteorological Agency of Ethiopia and cover the period between 1981 and 2010. 5 Howick Place | London | SW1P 1WG. 2 pp 92-97, 2009. The monthly rainfall data are for 132 points of 10 × 10 km grids reconstructed from weather stations and meteorological satellite observations, which cover the period between 1983 and 2013. This study evaluates recent spatiotemporal variability and trends in rainfall and temperature in the central highlands of Ethiopia by using monthly rainfall and temperature records. Spatiotemporal Patterns and Distribution of Temperature and Rainfall in Ethiopia 5.4. The F‐distribution test was used to determine the statistical significance of the trends. Corresponding Author.
