The writing of this book entailed perseverance and discipline, in addition to the support of many people without whom I would not have been able to complete it. First I would like to express my gratitude to my supervisor, Dr. Stephen Connelly at the University of Sheffied, UK, for his valuable guidance, attention to detail, hard work, and support throughout the preparation and writing of this book. I am sure it would not have been possible without his help. I would also like to thank Dr. Glyn Williams for his useful input.
Special thanks to Eng. Paul G. Weber, German International Cooperation (GIZ) team leader of the Agricultural Water Management Project at the Ministry of Agriculture and Land Reclamation in Egypt, for his professional and academic support. Thanks to my colleagues at the Ministry of Agriculture and Land Reclamation and the Ministry of Water Resources and Irrigation for their assistance. Many thanks to all the ministry staff at governorate level in Kafr al-Sheikh and Fayoum governorates who supported me in conducting the field work that allowed me to do this research and contribute to knowledge in this field. The contents of this book do not, however, reflect the official views of the GIZ, the Ministry of Agriculture and Land Reclamation, or the Ministry of Water Resources and Irrigation. Responsibility for the information and views expressed in the book lies entirely with the author.
(p.x) Last but not the least, my family: to my late father, who taught me the value of knowledge and perseverance, to my mother who was always there for me, sisters and brothers who were always supportive, and the one above all of us, the almighty God, for giving me the strength to continue.
