Investigation of the agricultural water management mechanisms in Zarindasht county, Fars Province, Iran.

摘要

Field surveys were carried out to investigate the agricultural water management mechanisms in three fields of irrigation sources in Zarindasht county (Fars Province, Iran), water transfer and in farm water consumption level. Questionnaire was used to collect data and its reliability was confirmed by Cronbach's alpha of 0.83, 0.72 and 0.85 in three fields of irrigation resources, water transfer and in farm water consumption level, respectively. Questionnaire validity was also confirmed by professors of agriculture training department of Tehran University and experts were related to water management. Statistical population consisted of 4648 individuals of Zarindasht farmers. Using Cochran's formula, sample size was estimated approximately 150 individuals. To select the samples, the multi-step sampling method was used. The results of priority setting of the agricultural water management mechanisms revealed that most of important mechanisms of agricultural water management such as feeding underground water, farmers' participation in providing the expenses of electronical wells, setting systems of determining the permissible Debby in field of irrigation resources and participation in different fields as an important mechanism in the field of water transfer channels and also using agricultural swages, land consolidation and consolidation in water consumption level are the last priorities of farmers point of view. Furthermore, the result of factorial analysis of agricultural water management mechanisms indicated the existence of six factors in irrigation resources field that most important factor was the factor of agricultural knowledge increase. In channels field, five factors were stated of which channel management was the most important. Five other factors were identified in farm water consumption level and the most important one was paying attention to training and extension. To achieve agricultural water management, some management mechanisms such as land consolidation, promotion of farmers' awareness through extension and education methods, canal management and farmers participation to conservation of irrigation networks, are necessary.
