O. Box 1176, Addis Ababa, Ethiopia. Accepted 17 September, 2013 This study attempts to contribute to our knowledge about Gamo, a member of the North Ometo subgroup, which is one of the four subgroups that constitute the Ometo group of the Omotic language family (Fleming, 1976; Bender, 2000). This paper characterizes some of the issues in the research of language and identity. It will attempt to employ the complementary perspectives of sameness and difference between Gamo, its sisters in the North Ometo sub-branch and its dialects. North Ometo comprises of several related languages and dialects of which Gamo is one. The exact relationship amongst the Ometo languages is not well known. Not equally well known is the relationship Gamo has with its sisters and daughters. The study tries to address issues concerning with misrepresentation of the Gamo language by the existing classification in one hand and what the self perception of the Gamo community likes on the other hand. This study aimed at examining linguistic facts and the Gamo speakers’ own understandings of their identities. To this end, the study has used linguistic, anthropological and sociolinguists attempt to characterize membership of Gamo based on linguistic facts and members’ self ethno-linguistic identificationi.

  • Land Use Patterns and Its Implication for Climate Change: the Case of Gamo Gofa, Southern Ethiopia
    Defaru Debebe. et al., IJSRR 2013, 2(3), 155-173 Research article Available online www.ijsrr.org ISSN: 2279–0543 International Journal of Scientific Research and Reviews Land Use Patterns and its Implication for Climate Change: The Case of Gamo Gofa, Southern Ethiopia Defaru Debebe* and Tuma Ayele Arba Minch University P.O.Box 21, Arba Minch, Ethiopia ABSTRACT Land is one of three major factors of production in classical economics (along with labor and capital) and an essential input for housing and crop production. Land use is the backbone of agriculture and it provides substantial economic and social benefits. Assessing past-to present land use patterns associated with the crop production helps to understand which climatic effects might arise due to expanding crop cultivation. This study was conducted to evaluate the land use pattern and its implication for climate change in Gamo Gofa, Southern Ethiopia. For evaluation, correlation and time series trend analysis were used. Results revealed that a significant reduction in cultivable land, which was converted into cropland and might increase deforestation and greenhouse gas emission, in turn induce climate change. The correlation between cropland and fertile (cultivable) land (r=0.22674) in 2005 improved to (r=0.75734) in 2012 indicating major shift of fertile land to cropland in seven years interval. On other side, twelve years (1987-1999 and 2000-2011) average maximum temperature difference in Gamo Gafa was increased 0.425oC with standard deviation 0.331. It is statistically significant (t =1.284, alpha=0.10) at 10% level of error. Moreover, the spatial differences in climate change are likely to imply a heterogeneous pattern of land use responses.

  • Hygienic Practice Among Milk and Cottage Cheese Handlers in Districts of Gamo and Gofa Zone, Southern Ethiopia
    Research Article Volume 12:2, 2021 Journal of Veterinary Science & Technology ISSN: 2157-7579 Open Access Knowledge; Hygienic Practice among Milk and Cottage Cheese Handlers in Districts of Gamo and Gofa Zone, Southern Ethiopia Edget Alembo* Department of Animal Science, Arba Minch University, Arba Minch, Ethiopia Abstract A cross-sectional questionnaire survey was conducted in Arba Minch Zuria and Demba Gofa districts of Gamo and Gofa Zone of the Southern nation nationalities and people’s regional state with the objectives of assessing knowledge of hygienic practice of milk and cheese handlers in both study area. For this a total of 102 farmers who involved in milking, collecting and retailing of milk were included in the study area. Data obtained from questionnaire survey were analyzed by descriptive statistics and Chi –square test, using the Statistical package for social science (SPSS Version 17). The participants of this study were woman of different age group and 27(52.9%) of participants in Arba Minch Zuria and 32(64.7%) in Demba Gofa were >36 years old. The majority of participants 21(41.2%) and 22(43.1%) were educated up to grade 1-8 in Arba Minch Zuria and Demba Gofa, respectively. This had an impact on hygienic practice of milking and milk handling. The difference in hygienic handling, training obtained and cheese making practice among the study areas were statistically significant (p<0.05). There was also a statistically significant difference in hand washing and utensil as well as manner of washing between the two study areas (p<0.01). Finally this study revealed that there were no variation in Antibiotic usage and Practice of treating sick animal in both study area (p>0.05) with significant difference in Prognosis, Level of skin infection and Selling practice among study participants in both study areas (p<0.05).

Chencha district in the Southern region hosted the first apple trees introduced to Ethiopia and grown for a long time; however, the achievements from apple production so far remained minimal. There is inadequate information on productivity and variety identification. Therefore, a survey on productivity and variety identification of introduced apple trees in Chencha district of Gamo Gofa Zone was carried out in 2013/14 cropping season. The study was aimed to assess status of apple production and productivity, investigate apple tree management practices carried out by the growers and identify apple varieties and rootstocks. A total of 181 randomly selected respondents were interviewed using semi-structured questionnaire from nine administrative units (kebeles).

In all sorts of circumstances, he remained calm and kind, and when I had questions, he was always there to answer them. In addition, he and his family were very hospitable and they taught me a lot about Ethiopian culture. The second person I want to express my appreciation for is my supervisor Pieter Lemmens. His experience was a great help during the sampling campaign and he was very patient with me. I am also very grateful to the people of Arba Minch who helped us during our sampling campaign, without their help the campaign would have been less fun and we might not have finished it before the start of the rain season (Tariku Anjamo, Communist Asemamawe, Selamnesh Tesfaye and Sebla).
