Agricultural Water Management Challenges in Qazvin Plain Irrigation Network

Irrigation network is a set of hydraulic channels and related structures that is created with the aim of transferring, distributing and delivering water fairly as well as efficiently. However, due to constraints resulting from type of management and maintenance, climate changes, social and cultural characteristics of users, and financial issues, their performance are usually faced with major challenges. Qazvin irrigation network is one of the modern networks in the country and after more than 40 years of implementation of this network, many problems and challenges in the field of agricultural water management are observed in this network. The purpose of the present research is to identify the important challenges in the field of agricultural water management in Qazvin plain irrigation network, to investigate the importance of challenges and performance in relation to the challenges, and finally to provide practical strategies to improve the state of the system with a new approach by using Importance-Performance Analysis technique. The method of conducting the study to identify the challenges has been library studies and then using Delphi technique. Furthermore, the importance of the challenges has been identified by using Best-Worst method. Evaluating the responce of the officials authorities  to the challenges using Importance-Performance Analysis technique, demonstrates that the challenges of lack of enough motivation in farmers to reduce agriculture water consumption, lack of governmental supports for established organizations, lack of supervision on implementation of crop patterns and cultivation area, budget issues, and lack of sufficient training for farmers, in ordre are five challenges in the first quadrant of the importance-performance matrix that should be prioritized for improvement. Several practical solutions to solve the challenges for Qazvin plain irrigation network such as doing more support from government in terms of using suitable irrigation methoed while considering the approved crop pattern and providing clear information for the statue of current situation and making coordination among all types of involved sectors are presented in the results section.
