Abstract: The focus of this study was to determine the impact of training and development on the employees’ performance and effectiveness at District Five Administration Office, Addis Ababa, Ethiopia. In this study we employed cross sectional institutional based quantitative research method. Data were collected using Likert’s scale tool from 100 employees after selecting participants using systematic random sampling technique. Ninety-four complete questionnaires with a response rate of 94% were considered during analysis. Training and development had positively correlated and claimed statistically significant relationship with employee performance and effectiveness. It is recommended that District Five Administration Office shall maintain providing employee training and development activities and ensure the participation of employees in planning, need or skill deficit identification and evaluation of training and development programs.

Abstract: Sixteen rainfed lowland rice genotypes were evaluated at three locations of eight environments in north western Ethiopia from 2006 to 2008 to identify stable and high yielding genotypes for possible release. The experiment was conducted using Randomized Complete Block Design with three replications. Combined analysis of variance showed highly significant differences among genotypes, environments and genotype by environment interactions for grain yield. The additive main effects and multiplicative interaction (AMMI) analysis of variance indicated that the genotype-by-environment interaction sum of squares was about 3.5 times larger than that for genotypes, which determined substantial differences in genotypic response across environments. The presence of genotype-by-environment interaction was clearly demonstrated by the AMMI model, when the interaction was partitioned among the first four interaction principal component axis (IPCA) which cumulatively captured 91.13% of the total GEI. The stability study indicated that among the tested genotypes, no variety was found to be stable; however, genotypes such as GEN13, GEN12, GEN10 and GEN9 showed high yield potential in favorable environments. In this study, environments (testing locations) fell into three sections, where most of the tested genotypes showed specificity. However, some of the genotypes were not found to be best to any of the environments. As a breeding strategy on rice in the country, it is suggested to execute national variety trial at a number of locations to cluster the testing locations into homogenous groups. This can bring a difference in the rice sector of the country. Among the tested genotypes, the highest grain yield was obtained from genotypes GEN13, GEN12 and GEN9 (4.07, 3.96 and 3.69 t ha-1, respectively) across environments. Out of the tested genotypes, three genotypes were selected and verified, of which genotype “GEN9” has been officially released with the vernacular name “EDGET” meaning development, for large scale production.

Ethiopian Journal of Health Development , 2003,
Abstract: Background: The importance of local variations in patterns of health and disease are increasingly recognised, but, particularly in the case of tropical infections, available methods and resources for characterising disease clusters in time and space are limited. Whilst the Global Positioning System (GPS) allows accurate and easy determination of latitude and longitude, sophisticated Geographical Information Systems (GIS) that can process the data may not be available and accessible where they are most needed. Objective: To describe an appropriate procedure for interpreting GPS information. Methods: An example of space-time clustering of malaria cases around a dam in Ethiopia (106 cases in 129.7 child-years-at-risk) is used to demonstrate that GPS data can be interpreted simply and cheaply in under-resourced health service settings to provide timely and appropriate epidemiological assessments. Results: Malaria cases were clustered in time and space in the area surrounding a microdam. Conclusion: Quickly identifying disease foci using appropriate procedures in this manner could lead to better informed control and treatment activities which would represent a better use of resources as well as improved health for the community.

Woody Species Diversity and Structure of Agroforestry and Adjacent Land Uses in Dallo Mena District, South-East Ethiopia  [PDF]
Bikila Mengistu, Zebene Asfaw
Natural Resources (NR) , 2016, DOI: 10.4236/nr.2016.710044
Abstract: Sustainable farming practice that utilizes and conserves biodiversity, reducing negative impacts of agriculture on biodiversity and provides wood and energy to local community is a good solution to reduce deforestation and forest degradation. This study was carried out in Dallo Mena district of Bale zone to identify woody species diversity in homegarden agroforestry practices, shade grown coffee agroforestry practices and adjacent natural forest, and to show how land use and management practice determine the plant species diversity. The study site was selected based on spatial analogue approach. In each land use, a plots of 10 m × 10 m size was drown by using systematic sampling method following the transect line. A total of 36 sample plots were sampled along the transect line laid down inside each land uses. In each plot, woody species were counted and the diameter and height of trees and shrubs were measured. Based on this inventory a total of 39 woody plant species which are about 23, 10, 15 woody plant species were recorded from natural forest, shade grown coffee agroforestry and homegarden agroforestry practices respectively. These species were classified belonging to 24 families. The Shannon Wiener diversity index used to estimate species diversity ranged from 0.14 to 2.54 with a mean of 1.47. Also 21% woody species similarities were observed between those three land uses. The result shows that both agroforestry practices (shade grown coffee and home garden agroforestry practices) and adjacent natural forests are conserving several woody species diversity in its system.

Journal of Politics and Law , 2009, DOI: 10.5539/jpl.v2n4p77
Abstract: Humans require plant resources to satisfy their basic needs for clothing, food, medication, shelter, and so on. In order to conserve and sustainably use these resources, the CBD, and the FAO-Treaty on PGRFA exist internationally, and for example the African Union Model Law exists regionally to provide frameworks for how these resources are to be accessed and how the benefits obtained from their utilization should be allocated. As a signatory to the CBD, Ethiopia issued its ABS law in 2006. Ethiopia has signed material transfer agreements on teff (gluten free and nutritious) and vernonia (the green chemical plant of the 21st Century) with two European-based companies. This article seeks to interpret and discuss the terms of the agreements on teff and vernonia. Furthermore, it analyzes the implications of the terms of the agreement for the realization of the objective of the CBD (e.g. access, benefit sharing and conservation).

Quantification of drought tolerance in Ethiopian common bean varieties  [PDF]
Asrat Asfaw, Matthew W. Blair
Agricultural Sciences (AS) , 2014, DOI: 10.4236/as.2014.52016
Abstract:

Understanding the level of drought tolerance of the varieties available in each country is of paramount importance for breeding common bean for drought adaptation. The goal of this study was to evaluate 25 common bean genotypes of which 24 were released/recommended varieties for production by farmers and one was a drought tolerant check. The genotypes were planted at two sites in Ethiopia, Hawasssa and Amaro, using variable sowing dates, one that was early to avoid drought and one that was late to expose the crop to drought. The experiments were repeated over two years in Hawassa and one year in Amaro. This resulted in treatments with high and low total seasonal rainfall and six environments for analysis. The impact of drought stress on the trait expression of the varieties was not uniform across traits assessed and varieties tested. The effect of drought on photosynthate translocation and partitioning traits was much greater than on yield component traits in the varieties studied. This indicating less breeding efforts has been made in improving the varieties ability to mobilize photosynthate to the developing grain as compared to the yield component traits. Drought tolerant varieties like Hawassa Dume maintained better photosynthate translocation and partitioning than the drought sensitive varieties like Brown Speckled bean. Hawassa Dume also showed better yield stability and performed well under both drought stress and nonstress conditions. Our results indicate the relevance of high levels of photosynthate translocation and partitioning as an effective selection objective for improving drought tolerance in common bean. The information generated on the drought tolerance of the available varieties should help in the design of a breeding strategy that incorporates adaptation traits with commercial characteristics preferred by common bean farmers for varieties to be grown in diverse environments.

Behavior of Bread Wheat (Triticum aestivum L.) Male Sterilized with Cytoplasmic-genetic and Chemical Systems and Their Impact in Hybrid Seed Production
Asfaw Adugna
Asian Journal of Plant Sciences , 2005,
Abstract: In this study the two pollination control systems, i.e. Cytoplasmic Male Sterility (CMS) and the use of Chemical Hybridizing Agents (CHA), were compared to discover their efficiency for the sterility reaction and their impacts in hybrid seed production. The result has shown that both systems were equally effective in their sterility performance. However, CHA resulted in reduced out crossing percentage due to female sterility, germination percentage and hundred seed weight of the hybrid seed due to toxicity. Overall the CMS system was better than the CHA system (based on the particular CHA used in this study) for attributes related to hybrid seed production.
