    Assessing Determining Factors of Best Risk Management Practice of Ethiopian Commercial Banks
    (2016-01) Nigussie, Worku; Gebrehiwot, Gebremedhin
    The paper is about “Assessment and Evaluation of best risk management practices” of commercial banks in Ethiopia based on fifteen commercial banks operating in Ethiopia. The number of respondents was eighty. While collecting the requisite data, five points Likert Scale has been used. The objective of the study was to critically examine determining factors of best risk management practices of Ethiopian commercial banks i.e., types of risk facing a bank, The extent in which the management and staff members of commercial banks understand and implement risk management and if or not the staff members of the selected commercial banks aware of the risks associated with their actions and goals. The study also examines how far the banks follow the guidelines of National Bank of Ethiopia regarding risk management. For this study there are six independent variables: understanding risk and risk management (URM), risk assessment and analysis (RAA), risk identification (RI), risk monitoring (RM), Risk Evaluation (RE), required policy in place (RP) and one dependent variable, RMP. Initially, data reliability was found by applying Cronbach’s alpha. So regression model was applied to analyze the impact of independent variables on dependent variables. From the analysis it was concluded that there were five variables which have positive significance impact on the dependent variable RMP. The study also reveals that credit risk, market risk and operational risk are the major risks to the bankers. Key words: Commercial Banks, Risk Management, and Risk Management Practices

    Carbon Stock and Its Variations along Environmental Factors in Gendo Moist Montane Forest, East Wollega Zone, Western Ethiopia
    (Addis Ababa University, 2016-08) Nigussie, Worku; Nigussie, Worku (PhD)
    Global climate change is an environmental problem in today’s modern world because of the change in global weather pattern. The study was conducted to estimate the carbon stock and its variations along environmental factors in Gendo (Gura Tirigni) forest as potential sink for climate change mitigation. Forest plays important role in the global carbon cycle as carbon sinks of the terrestrial ecosystem. Estimations of forest carbon stocks are based on the estimation of forest biomass. Tree species data collection was done by complete listing method. Soil and litter data collection had also been carried out using representative sampling. The result of the present study showed that 4687 trees and shrubby trees had a DBH ≥5 cm. From this study the mean total carbon stock of Gendo forest was 564.96±27.05 ton ha-1. The mean aboveground carbon, belowground carbon, litter carbon and soil organic carbon (0-10cm soil depth) were: 128.60±7.53 ton ha-1, 26.52±1.62 ton ha-1, 3.12±0.25 ton ha-1, and 94.96±4.61 ton ha-1 respectively. Carbon stock variations in different pools along environmental factors (altitude, slope and aspect) were recorded. LC along altitudinal gradient and SOC along altitude, aspect and slope gradients show significant variations. Keywords: Biomass, Carbon pools, Carbon stocks, Environmental factors, Gendo forest
