    Impact of Land Use/ Land Cover Changes on the Environment and Socio-Economy of the Smallholder Farming Community: The Case of Lude Hitosa District, Oromia Region, Ethiopia
    (Addis Ababa University, 2022-12-20) Dawit Solomon; Feyera Senbeta (Professor)
    Understanding the process of land use/ land cover (LULC) change and its implications has paramount importance for the sustainable management of natural resources. This study assessed the trends of LULC change and its implications on the environment (land, forest, and water resources) and livelihoods of the people in the Lude Hitosa district, central-eastern parts of Ethiopia. Remote sensing data (Landsat imageries) and socio-economic surveys were used to unveil the LULC dynamics in the study area. A socio-economic data was obtained through a questionnaire survey, focus group discussions (FGDs), field observations, and key informant interviews (KIIs). As a source of Landsat imaginers, the Ethiopian Space Science and Geospatial Institute (ESSGI) and online archives of the United States Geological Survey (USGS) from 1984 to 2022 were used. The LULC change analysis was made using ArcMap 10.8, R studio Rstudio-02.2-4, quantum GIS (Q GIS), and Microsoft office software. The socioeconomic data collected through a questionnaire survey were analyzed using SPSS (v. 20). The LULC change analysis revealed significant changes in the LULC change between 1984 and 2022. Forest cover, grassland, and shrub decreased by 12.77%, 22.23%, and 1.78%, respectively. Crop/agricultural land, settlement, and bare land had increased by 21.86%, 10.18%, and 4.75%, respectively. LULC change has significantly impacted land, forest, and water resources, thereby affecting people's livelihoods. The communities face severe food insecurity, scarcity of land, shortage of animal feed, reduction of water sources, etc. Therefore, appropriate measures that ensure the wise use of natural resources and efficient land utilization are critical.

    The Impacts of Quality Management on Performance Improvement in the case of Ethiopian Commodity Exchange: the mediation effect of Leadership
    (AAU, 2024-02-20) Dawit Solomon; Mohammed Seid (PhD)
    The study aimed to examine the mediation function of authority in navigating the connection between quality assurance and effectiveness enhancement via the Ethiopian Grain Trade (ECX). Formal surveys were conducted with 139 participants, using inductive and descriptive data. The results showed that the Ethiopian commodities Exchange's existing checks and balances were of passable efficacy. However, there is potential for development. Regulatory authorities should prioritize improving supervision procedures and implementing strong quality management procedures. This can be achieved by encouraging an environment of ongoing development and highlighting the value of quality control across all aspects of the business. The research also showed a strong and favorable correlation between boosting productivity, direction, and excellent assurance. The relationship between quality control with productivity enhancement seems to be somewhat mediated by administration. This highlights the importance of strong management in advancing exchange-controlled exchanges effectiveness programs. The study recommends management across the Ethiopian Stock Market embrace the development of a society rooted in greatness through ongoing enhancement. This can be achieved by fostering tasks that promote productivity advantages and cultivating strong managerial skills. It is also crucial for administrators and government organizations to establish processes for ongoing improvement and regular review and improvement of inspection procedures.
