Résumé
This dissertation explores the possible differential influence of territorial features on the performance of irrigation improvement programs in Egypt. The study was conducted in El-Mahmoudia main canal, Beheira governorate which is one of the command areas in Nile Delta where Integrated Irrigation Improvement and Management Project (IIIMP) was applied in accordance with the principles of Integrated Water Resources Management (IWRM). Three branch canals on El-Mahmoudia main canal were purposively selected to represent the current situation of improved and unimproved irrigation systems. The first is a successful improved branch canal (Kafr Nikla) ; the second is relatively less successful improved branch canal (Besentway), and ; the third one is unimproved sub-branch canal from El-Mahmoudia canal (Ganabet Bastara & El Ziana). A simple random sample of 220 water users (25%) was drawn from the total estimated number of water users on the selected branch canals (160 from improved branch canals and 60 for unimproved ones). Mesqas’ locations on branch canals, and water users’ land locations on mesqas (upstream/ midstream/ downstream) were taken into account to represent the current situation of irrigation systems in these areas. Data were collected through personal interviews by using a semi-structured questionnaire designed and pretested to achieve the study objectives. Findings indicate that in improved areas, there are statistically significant and positive correlations between specific proximity dimensions (cognitive, and social) and each of IIIMP and BCWUAs’ performances. Meanwhile, results point to a significant positive relationship between organizational proximity and IIIMP performance. Among the different proximity dimensions, there are significant positive relationships between : cognitive and social ; cognitive and organizational, and ; social and organizational proximities. Comparing the studied branch canals (Nikla and Besentway) within two different territories, there is a significant positive correlation between social proximity and mesqas’ geographical location of the successful branch canal (Nikla). However, there are significant and negative relationships between Besentway’s mesqas geographical locations and each of : cognitive proximity, social proximity, and IIIMPs’ performance. These findings lead to an empirical evidence that cognitive, social, and organizational proximities have a strong role in supporting the implementation of IWRM.
