Abstract

Extended Abstract
Introduction
Education and Extension factors, both in improving the productivity of water resources and in observing the approved cultivation pattern by farmers, are among the factors that affect many performance indicators of irrigation networks. The effect of this training should be systematically investigated in the chain of water, food, and energy Nexus in irrigation networks.
Methodology
The trainings were analyzed in the developed Nexus conceptual model in the borders of the Qazvin irrigation network using a system dynamic approach. The presented quantitative model in this section includes eight subsystems, two of which are directly affected by training factors. The two considered subsystems are "Agricultural Development Limitation" and "Solutions for Solving Unsatisfied Water Needs". The Nexus index was defined as a linear combination of some indices including water efficiency, energy efficiency, Production Utility, and water delivery adequacy.
Results and Discussion
In this research, taking into account the incremental changes in the number of hours of extension training, in three options of 20, 40, and 60%, the number of changes in the indicators of network adequacy and agricultural water productivity, and finally the nexus index were investigated.
The amount of effectiveness improvement in the three options of 20, 40, and 60% was 0.35, 0.34, and 0.32 percent respectively, and the effectiveness rate for the three options was 0.072, 0.087, and 0.104 respectively. This means that increasing the amount of training, even to the smallest amount, can have a great effect on improving the performance of the network in terms of improving water consumption and observing the cultivation pattern in line with water demand management. Considering the effectiveness of the options, it can be claimed that with the maximum increase in education, we can expect more effective changes in the above-mentioned fields.
Conclusions
It can be claimed that one of the most important factors under agricultural services, whether to observe the cultivation pattern or to improve water consumption, is extension training. According to the results, it can point out the importance of the effect of training parameters along with other technical parameters on the performance of irrigation networks and the security of water food, and energy resources in the Nexus chain.
