  • Spatial Distribution of Glossina Sp. and Trypanosoma Sp. in South-Western
    Duguma et al. Parasites & Vectors (2015) 8:430 DOI 10.1186/s13071-015-1041-9 RESEARCH Open Access Spatial distribution of Glossina sp. and Trypanosoma sp. in south-western Ethiopia Reta Duguma1,2, Senbeta Tasew3, Abebe Olani4, Delesa Damena4, Dereje Alemu3, Tesfaye Mulatu4, Yoseph Alemayehu5, Moti Yohannes6, Merga Bekana1, Antje Hoppenheit7, Emmanuel Abatih8, Tibebu Habtewold2, Vincent Delespaux8* and Luc Duchateau2 Abstract Background: Accurate information on the distribution of the tsetse fly is of paramount importance to better control animal trypanosomosis. Entomological and parasitological surveys were conducted in the tsetse belt of south-western Ethiopia to describe the prevalence of trypanosomosis (PoT), the abundance of tsetse flies (AT) and to evaluate the association with potential risk factors. Methods: The study was conducted between 2009 and 2012. The parasitological survey data were analysed by a random effects logistic regression model, whereas the entomological survey data were analysed by a Poisson regression model. The percentage of animals with trypanosomosis was regressed on the tsetse fly count using a random effects logistic regression model. Results: The following six risk factors were evaluated for PoT (i) altitude: significant and inverse correlation with trypanosomosis, (ii) annual variation of PoT: no significant difference between years, (iii) regional state: compared to Benishangul-Gumuz (18.0 %), the three remaining regional states showed significantly lower PoT, (iv) river system: the PoT differed significantly between the river systems, (iv) sex: male animals (11.0 %) were more affected than females (9.0 %), and finally (vi) age at sampling: no difference between the considered classes. Observed trypanosome species were T. congolense (76.0 %), T.

Box: 307 Jimma, Ethiopia Abstract African Animal Trypanosomosis is one of the major impediments to livestock development and agricultural production in Ethiopia, which negatively affect the overall development in agriculture in general, and to food self- reliance efforts in particular. Currently, about 180,000 to 200,000km 2 of fertile arable land of west and southwest of the country is underutilized. Darimu district is one of the areas with such problems. Therefore, a cross-sectional study was conducted with the objectives of assessing the prevalence of Bovine Trypanosomosis and determines spatial distribution and apparent density of tsetse and other biting flies in the study area. In current study, a total of 650 blood samples were collected from randomly selected animals and subjected to Buffy coat parasitological laboratory technique and positive samples were subjected to thin blood smear followed by Giemsa staining. Out of the total blood sampled, 7.1% tested positive for trypanosomosis. Out of positive cases, Trypanosoma congolense (82.61%) was the dominant trypanosome species followed by mixed infection ( Trypanosoma congolense and Trypanosoma vivax ) (8.67%).

The parasitological examination was conducted using Buffy coat technique while vector survey was conducted using odour baited Monopyramidal trap. The objective of the study was to determine the prevalence of trypanosomiasis in cattle, to determine fly density and to identify associated risk factors. From 392 Blood samples were collected, 45(11.5%) were found to be positive by Buffy coat technique and trypanosome species identified by their motility were T.congolense 40 (88.9%) and T.vivax 5(11.1 %) and Trypanosoma congolense was the dominant species. A total of 52 Monopyramidal traps were deployed and 1836 (73%) tsetse flies and 676(26.9%) biting flies were caught. From flies captured, 971(52.9%), 540(29.4%) and 325(17.7%) Glossina morsitans sub morsitans of savannah flies, Glossina fuscipes fuscipes of reverine and Glossina pallidipes of savannah species were identified respectively. The overall apparent densities fly / trap / day (FTD) were 17.7 and 6.5 for tsetse and biting flies respectively. There was no statically significant difference (P > 0.05) in the prevalence of trypanosome infection between sex group while statistically significant difference was observed between age group(x2=41.0, p=0.000, p<0.05).

  • Causes of Climate Change and Its Coping up Strategies in Case of Gechi Woreda, Bunno Bedelle Zone,South Western Ethiopia
    Journal of Resources Development and Management www.iiste.org ISSN 2422-8397 An International Peer-reviewed Journal Vol.66, 2020 Causes of Climate Change and Its Coping Up Strategies in Case of Gechi Woreda, Bunno Bedelle zone,South Western Ethiopia Habib Bati Geda Department of Ecotourism and Biodiversity conservations Mettu University, P.O.Box ,318, Bedele,Ethiopia Abstract This research was conducted to assess Causes of climate change and its coping up strategies in case of gechi woreda, south western Oromia, Ethiopia. Climate change refers to long term fluctuations of temperature, precipitation, wind and other elements of Earth’s climate system. It is a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global and/or regional atmosphere. In order to achieve the objective of the study both primary and secondary data were used. The quantitative data was analyzed using frequency, percentage and mean while the qualitative data was used to triangulate and substantiate the study. To select the sample population, two different sample sizes were used with different sampling procedures stratified random sampling techniques was used to classify 2 kebeles of the woreda in 2 separate strata and simple random sampling technique was used to select kebeles that represent those strata. The result of the study indicated that Natural climate variability observed over comparable time periods in the types of changes of temperature and rainfall. It occurs because of internal variability within the climate system and external factors. The external causes may be natural or human induced activity. Human activities cause climate change mainly due to fossil fuel burning and removal of forests.

  • A Study Case on Coffee (Coffea Arabica): Limu Coffe
    A study case on Coffee (Coffea arabica L.) Limu Coffee Laurent Bossolasco Sous la direction de François Verdeaux Ethiopie, Octobre 2009 “It is also the coffee type. It took its name from the Kaffa province1 where it grows spontaneously, and where, once ripened, it is picked without any effort by the natives as a wild fruit. I found out about this in many scholarly books: all admit that south western Abyssinia is the only country of the world where coffee grows as a natural soil product. Weather conditions not found elsewhere in the universe, the alliance between tropical heat and mountainous altitudes realized in this Earth paradise the unique miracle.” Ménélik et nous, Hugues le Roux (Paris, 1903) Coffea Arabica L., as it has been written and rewritten, finds its birthplace in south western Ethiopian forests even if Linnaeus gave its scientific name in 1753 paying tribute to his future country. The relationship between Ethiopians and coffee is deep-rooted, and coffee production and consumption are closely intertwined with Ethiopian history, culture and economy. Coffee has been cultivated, traded and consumed over centuries and still play a significant role in the daily life of most Ethiopians and for the state of Ethiopia as a whole (Stellmacher, 2007). As told me Ato Tarreessa Fayisa, a peasant living Limu Genet (Limu Kosa woreda, Jima zone, Oromiya region): “Coffee is the backbone of our life”. Coffee production is of highest importance for monetary income generation, followed by honey and livestock production. Farmers realizing income through surplus of any production rely on coffee since the greatest share of income is gained through coffee production which is the surplus production archetype.
