    Climate-Resilient Environmental Planning in the Awash River Basin, Ethiopia: A Geospatial Assessment of Environmental Change, Flood Hazard, and Nature – Based Solutions
    (Addis Ababa University, 2026-06-01) Abayneh Tilahun; Ephrem Gebremariam; Hayal Desta
    Flooding is a major environmental factor in the Awash River Basin (AWB) which is accredited by a concerted transformation of land-use change with climatic variability, topographical landscape, and soil degradation. The current dissertation has attempted to outline the flood prone area of the basin using the GIS and remote sensing as well as understand the etiology and the effects of floods, the dynamics of climatic changes, the future losses of the soil and prescribe some sustainable nature based methods of mitigation. The analysis of climatic trend by non-parametric techniques has shown that there is a remarkable reduction in annual and seasonal precipitation over the last forty years including the fact that temperatures are characterized by their continuously increasing pattern especially during spring and autumn. The decrease in vegetation cover and rise in surface temperatures are supported by satellite-based NDVI and land-surface temperature, thus worsening the situation of hydrological extremes. The long-term period in the range of 1990 to 2020 covering land-use and land-cover change (LULCC) show strong increment in the extent of the urban (by 160%), agricultural land (15%) and wetland areas, which are accompanied by considerable declines in bare land area and deep water bodies, which is mainly explained by the high population growth in the period. Such changes have altered surface runoffs pattern and vulnerability to flood significantly. The map of flood hazard susceptibility prepared with the help of multi-criteria decision-analysis framework which considers the elevation, slope, drainage density, precipitation, soil type, riverine proximity, and LULCC reveals that over half of the basin is at high to medium risk of floods, with the model validated by ROC-AUC evaluation. A soil erosion evaluation using the Universal Soil Loss Equation (USLE) indicates the strong spatial variability in soil erosion and subsidiary of sediment transportation with the majority of the erosive activity taking place in the upper basin areas thus highlighting the significance of land-management measures and rainfall erosivity. Lastly, suitability mapping of nature-based solutions reveals that vast areas (38%) of the basin are highly to extremely appropriate to interventions like afforestation, wetland restoration as well as sustainable land management. In general, it could be concluded that the findings offer a unified scientific foundation of the flood risk mitigation, soil protection, and nature based climate-resilient planning in the Awash River Basin as a means of sustainable development and informed decision-making.

    The Practice of development Journalism in the Ethiopian media landscape
    (Addis Ababa University, 2017-06) Abayneh Tilahun ; Agaredech Jemaneh
    This research attempted to study the practice of development journalism in Ethiopian media landscape, through comparing the development issue coverage and challenges of government and private owned media. It was informed by public serving development journalism and social responsibility theory of theoretical frameworks. Its focus was on a practical nature of development news coverage and challenges in Ethiopian media. The research emphasizes on the ownership, actors, nature, sector, aim, source and trend of development issue coverage and the challenges of the coverage. A Content analysis and in-depth interview was conducted on the news carried by the four selected media to explain the extent and explore the challenges of coverage of development issues respectively. The analysis shows that both the government and privately owned media in Ethiopia had their own kind of problems in their practice of development journalism: The government media, Focuses on the government development actor’s success only. They are not applying critical journalism. To the worst, the government media are not considering the development contribution of non state actors . The government media are event oriented They luck professional integrity for the public interest by ensuring transparency and accountability by exposing corruption and investigating crimes that hinder the national development process through ethically participation in the development activity in a process oriented manner and are not finding solutions for development problems through participating the grass root. Structural censorship, Self censorship of journalists, unethical conduct of journalists, professional limitations, law commitment of media leaders to enforce the policy, lower level of Public culture of information exchange, trespassing of editorial policy and government official’s perception of DJ as a development success only reporting are challenging the practice. In contrast, privately owned media in Ethiopia covered less development issues than the government media, gives very little time and space for the development issues of Ethiopia compared to the government media. But, in that little amount of coverage, they focus on government development actors failure and dissimulate non-state actors failure. Paradoxically, the private media in Ethiopia similar to government media are not applying investigative journalism and watchdog the public property. They have no role in exposing corruptions and crimes committed on public properties. Practically, they are also event oriented and Addis Ababa based one side story tellers more than the government media. Resource limitation (human, Material and financial), wrong perception of government PR officers and officials towards private media and prohibition of information, government tax and null incentive for private media, lower level of public culture for information exchange and freedom of expression are the top line challenges which affected their coverage of development issues of the private media

    Spontaneous Development of Urban Centers an Analysis of the Transformation Process of Adama and its Primary Commercial Centers
    (Addis Ababauniversity, 2006-03) Abayneh Tilahun ; Berhanu Wubshet
    Central areas in Adama have been transforming into either of two forms - blighted and decayed areas or congested and very poor quality urban environments. It seems that the problem exists as urbanization takes place in the context of relatively slow economic growth, ineffective legal andregulatory frameworks and perhaps an absence of a strong and functional social order, all leading to spontaneous urban development. The aim of this study is to understand how these urban areas became to be the way they are today. There have been a lot of studies on transformation of cities in the context of industrialized nations. It is not clear, however, whether or not thesestudies can explain the situation in the developing world. Attention thus far, in cities in the developing world, has been limited to amelioration of problems associated with poverty and delivery of infrastructure and social services. The quality of the urban environment was not considered as a priority. This study discusses the different stages in the transformation of central urban areas of Adama in general, and that of its commercial centers in particular, and the effects of the transformation process on the quality of the urban environment. life of the low and middle income inner-city residents of Addis Ababa. Financial, institutional and legal problems are also seen
