As one of the actors to adapt the global climate change, Ethiopia Cis designing and implementing climate resilient green economy (CRGE) strategy. One of those implementation strategies is the use of clean energy generation by using the untapped hydroelectric potential of the country . Ethiopia is at the booming age in its hydroelectric potential development. But, due to environmental degradation and lack of proper management the life span of such hydroelectric dams is under threat unless well organized and continuous integrated watershed management is implemented at national level. For instance, Gilgel Gibe 1 and 2 dams are generating about 30% of Ethiopia’s current electric demand and expected to serve for about 50-70 years if the watershed is well managed. However, investigators find out that the siltation and eutrophication of the Gilgel Gibe I dam is very huge and the dam is under threat. In response to this alarm call we organized a national workshop in 2010 in collaboration with all stakeholders. Several integrated watershed management activities were implemented with the involvement of all stakeholders actively. The second consultative national workshop was organized to review the ongoing activities and discuss the way forward with all stakeholders. We are very pleased to express our warm interest to collaborate on Omo-Gibe basin integrated watershed management with any responsible actor. Kora Tushume Dean for Business and Economic Development and Vice President Jimma University Negash Teklu Executive director, PHE Ethiopia Consortium 4 Proceeding of The Second National Consultative Workshop on Integrated Watershed Management on Omo-Gibe Basin Acknowledgement PHE Ethiopia Consortium would like to extend its special thanks to CSSP, which provided us all the financial support required to conduct the workshop, and to Jimma University for availing a nice, comofrtable meeting hall, and other logistic supports. It is also our pleasure to thank the Ethiopian Electric Power Corporation for their relentless effort and cooperation for the successful completion of the workshop. All government offices and non-government organizations would also be appreciated for their inexorable contribution during and after the workshop. The Consortium would also acknowledge all those who took part in the workshop and contributed valuable ideas either presenting their paper and/or actively participating and generating ideas for the purpose of the successful outcome of the workshop. Finally, PHE EC would like to thank all those who have direct and indirect role to the successful completion of the workshop.

Introductory sessions of the workshop 1.1. Scope and Objectives of the workshop he scope of the workshop is limited to the upper Omo-Gibe basin focusing on Gilgel Gibe I and II Tdams with the understanding of the need to gradual expansion of the focus area to Gilgel Gibe III and the lower Omo-Gibe basin. The second national consultative workshop on Omo-Gibe basin was thus organized to open a forum of discussion with the major stakeholders to review the performances and share the experiences of different stakeholders and pave the way for further cooperation and synergy in conserving the Omo-Gibe basin. General objective. The general objective of the workshop was to strengthen a forum of multi-sectoral partnership that was established in the first stakeholders meeting and reviewing the performance of the stakeholders in conservation of Omo-Gibe basin. Specific objectives: To revive a fresh discussion on the conservation of Omo-Gibe river basin To review the performance of stakeholders in the last five years To strengthen the multi sectoral engagement of stakeholders To discuss on the research findings of Jima university To discuss on performance of governmental and nongovernmental organization in watershed management on the upper catchment woredas. To create a forum where the stakeholders share their experiences and have a joint plan for the coming five years. 1.2. Welcoming speech Dear, Tesfaye Fichalla, advisor to the minister, Ministry of Water, Irrigation and Electricity Dear, Negash Teklu, Executive Director for PHE Ethiopia Consortium Distinguished participants, Ladies and Gentlemen: It gives me a great pleasure to welcome all of you and chair the opening ceremony to “the Second National Consultative Workshop on Integrated Watershed Management on Omo-Gibe Basin” jointly organized by Jimma University and PHE Ethiopia Consortium. The significance of integrated watershed management in Omo-Gibe Basin was being well noticed by several stakeholders in Ethiopia, East Africa and at international level at large due to the untapped 6 Proceeding of The Second National Consultative Workshop on Integrated Watershed Management on Omo-Gibe Basin hydrologic and biodiversity potential of the basin. The first joint workshop on integrated management of Omo-Gibe Basin was held in 2010, before five years here in Jimma University and resulted in significant output to create awareness on the siltation problem of Gilgel Gibe I dam and alternative measures. After long lasting debate in several similar workshops we reached consensus on the need of immediate integrated watershed management activities by mobilizing available resources and all stakeholders. Accordingly, Ministry of Water, Irrigation and Electricity, take the leading role to manage the dam and the associated siltation risk. I believe that the Minister organization took the expected leading role and developed proposal in collaboration with Jimma University, Jimma Zone Administration and all the Districts in the catchment namely, Sekoru, Omonada, Tiroafeta, Kersa, Sekachekorsa and Dedo. It has been about three years since the fund was being released and several soil water conservation measures and other related activities have been implemented. Dr. Fikre Lemessa, President, Distinguished participants, Jimma University Ladies and Gentlemen: As the main nearby stakeholder, Jimma University has been undertaking several scientific researches to minimize the siltation problem of Gilgel Gibe I Dam and to improve the livelihood of local communities by organizing multidisciplinary research themes. One of our efforts worth mentioning is the VLIR, IUC-JU project which has been launched since July, 2007 and undertaking holistic multidisciplinary researches within 8 sub-projects by participating more than 40 PhD researchers. Regarding the specific integrated watershed management, we believe that successful field experiments have been undertaking and it is
