    Acknowledgments

    This dissertation is an output of the scholarship from the Food Security Center, University of

    Hohenheim, which is supported by the German Academic Exchange Service (DAAD) and German

    Federal Ministry for Economic Cooperation and Development (BMZ). I would like to express my

    sincere gratitude to Dr. Hermann Eiselen PhD Grant from the Foundation Fiat Panis for financial

    support of the field research. I am also grateful for the logistic support of the ILRI-BecA

    collaborative project “Harnessing genetic diversity for improved goat productivity” which enabled

    me to smoothly conduct the field research.

    My heartfelt gratitude is due to my major supervisor Prof. Dr. A. Valle Zárate for accepting me as

    your student and continuously providing support and diligent guidance all along. Thank you very

    much for teaching me how to make objective and analytical arguments. I would like to express my

    sincere acknowledgement to my mentor Dr. André Markemann for the invaluable contributions

    starting from inception to the completion of the research project. Your constructive comments were

    always detailed and helpful. My deepest gratitude also extended to my other mentor Dr. Christoph

    Reiber for allocating your time to read and comment the manuscripts and provide professional

    guidance and advices. I also thank Philipp Muth for the assistance in the data analysis and

    interpretation of some results. I would like to offer my sincere gratitude to my fellow students and

    colleagues at the department of Animal Breeding and Husbandry in the Tropics and Subtropics for

    their encouragement, assistance and friendship. Thanks to Sekou, Dr. Kefelegn, Kerstin, Karin,

    Andrea, Dominique and Sigrid. I am also grateful for the support and insightful comments of Dr.

    Girma Kassie, Dr. Aynalem Haile, Dr. Barbara Rischkowsky and Dr. Tadelle Dessie.

    It would not be possible to conduct the field research without the collaboration of various offices

    and regional research institutions located around the project areas. Particularly, I would like to

    thank the staff of Abergele, Arbaminch and Gonder agricultural research centers for the kind

  • ii

    cooperation and provision of valuable information. I also thank Grum Gebreyesus and Temesgen

    Jambere for your assistance during data collection and group discussions.

    I am grateful for my mother Etalemahu Tesfaye (Emaye) who brought me up as a single mother and

    dedicated her life taking care of me and my two siblings. Sadly, she could not make it to see my

    success. Mother, may your kind soul rest in eternal peace.

    I am grateful to my wife Tigist Shibeshi who shouldered the burden of parenthood alone when I

    was away from home. Thank you very much for your sustained love, care and encouragement. For

    my Children Nati and Edom, I am sorry to be way for such long time, now it is over, we will be

    together once again.
