A new approach in irrigation of Sistan plain by applying special social, climatic conditions and available resources

Water and soil are the most important and main available capital available in geographical areas. Case study of large and fertile plains has always been considered as a turning point in terms of productivity and increasing efficiency in this sector. In addition, the social dimension has the most flexibility in the study of factors. This issue can pave the way for the formation of different approaches. In general, irrigation management is possible through three sectors: public (government), private sector and private organizations (water users). Irrigation plan of Sistan plain in 46000 hectares of lands of this region within the lands of Zabol, Hamun, Zehak, Hirmand and Nimruz cities in 17 civil development units and the form of water supply to the lands in the form of detailed studies in the fields of soil science, hydrology and is hydraulically operated. In this research, the conditions of implementation of this project in terms of the type of implementation and operation have been studied in detail. The results showed that in arid and semi-arid regions, special social conditions, the state of resources lead to the fact that the operation of irrigation projects requires special conditions and without considering the direct role of farmers in the form of cooperatives and Water groups should be able to achieve the best efficiency conditions.
