Abstract: The purpose / objective of this study is to provide new theoretical and empirical insights into joint project stakeholder related phenomena through the study of how stakeholders attempt to influence joint projects; and how a joint project management tries to manage these influences in joint multi-firm projects. Accordingly, the focus of this study is the evaluation of the stakeholder management protocol of joint projects performed by selected non-governmental organizations (NGOs) that are recently functioning in Ethiopia. For the reason that the overriding purpose of the study is to investigate the stakeholder management experience of the designated institutions as practiced in the selected projects, this study has made use of descriptive method of research design. In the meanwhile, mixed research approach has been adopted to carry out the study. Moreover, because it was possible to obtain the information the researcher needed from all stakeholders of the designated institutions simultaneously, the time dimension of the study is cross-sectional. The target population of this study is the entire project personnel, the relevant government officials, and project beneficiaries of the chosen projects, out of which 15% is taken as a representative sample. Because the appraisal principally targeted on those individuals who had experiences with project stakeholder management, a non-probability judgment sampling technique was adopted. Finally, the findings of this study highlighted the importance of stakeholder management in joint projects. Through the application of the ideas of stakeholder theory, the results of this study provided new theoretical and empirical understanding of how joint project stakeholders may influence the project management’s decision making during the project lifecycle. These findings also demonstrated how a joint project may analyze its stakeholder environment and respond to stakeholder pressures and unexpected events in the context of joint projects. Ultimately, the new knowledge of joint stakeholders’ influence strategies and better understanding of how a joint project can deal with stakeholder influences supports project managers in the development of effective project stakeholder management approaches.

Abstract: Soil stabilization stands as a vital process aimed at enhancing the structural qualities of expansive soil to bolster its stability. This involves meticulous compaction control, appropriate mixture ratios, and the introduction of suitable additives and stabilizing agents. Numerous infrastructure endeavors, including roads, railways, water reservoirs, and land reclamation ventures, demand substantial volumes of earth materials. However, regions featuring expansive soil, unfit for construction purposes, necessitate stabilization interventions. Utilizing local resources like sand, silt, lime, and fly ash can effectively stabilize such soil. The current research study centers on investigating the effectiveness of lime and fly ash as additives or stabilizers to heighten the engineering attributes of expansive soil. The research project systematically assesses the impact of lime and fly ash on crucial soil engineering properties, encompassing liquid limit, plastic limit, compaction characteristics, and the California Bearing Ratio (CBR). The experimentation involves varying proportions of lime (ranging from 3% to 12%) and fly ash (ranging from 10% to 40%) within the expansive soil. Outcomes indicate that the introduction of lime elevates the liquid limit, Maximum Dry Density (MDD), and CBR, while diminishing the plastic limit, and Optimum Moisture Content (OMC) of the soil. On the other hand, the inclusion of fly ash reduces the liquid limit, plastic limit, and OMC of expansive soil, concurrently increasing the MDD and CBR values. The primary aim of this research endeavor revolves around determining the viability of lime and fly ash as modifiers or stabilizers for expansive soil in the context of road construction. The study strives to pinpoint the optimal quantities of lime and fly ash that yield optimal performance, particularly in terms of CBR, when the soil functions as a subgrade in highway projects. The findings affirm that the amalgamation of lime and fly ash effectively stabilizes expansive subgrade soils, presenting an economically efficient solution. The results underscore that the incorporation of lime and fly ash augments the geotechnical qualities of expansive soil, rendering it a feasible choice for roadwork and other construction undertakings.

Abstract: The need for irrigation water would be influenced by the fluctuating meteorological effects under the circumstances of climate change, and irrigation water will always represent the majority of water use in Gobu Seyo district. The purpose of the study was to look into how climate change would affect the amount of water needed to irrigate pepper and potatoes. The entire crop water consumption as well as the irrigation needs for the current and upcoming decades were modelled using the CROPWAT 8.0 software. In addition to the base period (1990-2019), forecasts for the future scenarios (2023-2052) and (2053-2082) were made using a MarkSim-GCM and the output ensemble of 17 GCMs for the medium (RCP4.5) and high (RCP8.5) emission scenarios. The analysis shows that in both scenarios (RCP8.5 and RCP4.5) and time periods (2023-2052 and 2053-2082), the agricultural water needs of both crops increased from 4.18% to 7.49%. The change in crop water requirements was highest for the mid-term period under the high emission scenario (RCP8.5), and the lowest for the near-term period under the medium emission scenario (RCP4.5). The range of the crops chosen for the research area's irrigation water requirements was 0.29% to 6.12%. While RCP4.5 with near-term time recorded the least change, RCP8.5 with mid-term period showed the most increasing change. The results strongly imply that the research area's chosen crops' water and irrigation needs will be significantly impacted by future climatic changes. In order to enhance the low level of water usage efficiency now in place, it is advised that farmers, water managers, water user associations, and decision-makers collaborate in the future to increase water storage, distribution, and crop output.
