Climate Change and Trend Analysis of Temperature in Addis Ababa, Ethiopia

Abstract

Background: This paper presents the trend analysis of temperature in Addis Ababa City and the effect of climate change in the study area. The analysis is based on the temperature variation in the capital city of Addis Ababa over two stations - Bole and Entoto. Methods: The Mann-Kendall trend test and Sen’s slope estimate were employed to find the nature of the temperature trend and significance level in Addis Ababa city. Results: It was found that the Mann-Kendall statistic (Z) value for minimum, maximum and average temperatures for Bole station are 5.99, 3.32, and 6.14 respectively. The positive Kendall’s Z value shows an upward trend and implies an increasing trend over time. This indicates that there is a significant increase in the trend at a 5% level of significance since the p-value is less than the significant level (p-values (0.0001) < 0.05). Whereas for Entoto station, the Mann-Kendall statistic (Z) results are 1.64 for minimum, 0.85 for the maximum, and 1.40 for average temperature, and this positive value show an indicator of an increasing trend. However, the increase is not significant at 5% significant level since the p-value is greater than the significant level (p-value (0.219) > 0.05). Conclusions: From both the Mann-Kendall trend test result and Sen’s Slope estimator, it can be concluded that there is the tendency of temperature increments in Bole station. This could be due to the influence of climate change and can lead to weather extremes in the capital city. Therefore, the study recommend that the variability of temperature needs further monitoring technique, and there is a need to consider the increasing temperature trend to minimize its effects on human health.

Prevalence and Associated Factors of Malaria among Febrile Children in Afar Region, Ethiopia: A Health Facility Based Study

“…This study revealed that as the age of children increased, risk of malaria infection increased by three folds. This finding is in line with a study done in Malawi (31) and a study conducted in Uganda to assess the risk factors associated with malaria infection among under-five children (19), a study done in Zambia [45] and a study done in Awassa District, Ethiopia (32). This could be justified by this is the immediate time (4–5 years of age), in which children participate to look after the cattle.…”

The Neglected Traditional Enset (Ensete ventricosum) Crop Landraces for the Sustainable Livelihood of the Local People in Southern Ethiopia

“…The difficulty of the processing system might also be another reason for the reduction of enset production in the area. This result was similar to the study by Alemu and Sanford [ 39 ] that was done in the North Omo Zone, Ethiopia.…”

Genome-wide diversity and demographic dynamics of Cameroon goats and their divergence from east African, north African, and Asian conspecifics

“…A few goat populations, such as the Nigerian Dwarf goat, a variant of the West African Dwarf, are well-known for their prolificacy. Goats are also important sources of milk and meat and provide financial stability to pastoral communities and smallholder farmers in arid, semi-arid, and mountainous areas of Africa [9–13].…”
