Iran 0000-0001-9706-2723 Journal Article 2018 07 22 An effective factor in reducing the problems of modern cities is to use, regenerate and enhance green infrastructure to tackle the increasing problems of cities. From the one hand, the green infrastructure significantly influences the surrounding environment. On the other hand, the increase of the value added to the lands in the areas covered by these green elements can enrich the environmental quality in addition to improving all aspects of life. This study aims at investigating the effect of Isfahan Madis, as green infrastructures of Isfahan city, on the increase of value added to the adjacent lands. <br />Moreover, the impact of Madis on improving the quality of life, as well as Madis patterns in promoting less developed regions are put into further scrutiny. Therefore, the influence of Madis on land prices, the role of Madis on the quality and promotion of residents’ life and the living environment, as well as the use of Madis patterns in improving the quality of less developed regions can be stated as the research problems in this study. This study adopts a descriptive-explanatory research method. The results indicate that, despite the fact that wealthy people used to build their houses near Madis to benefit from the water and greenery in the past, the trend is reversed due to drought problems in recent years and providing privacy for the Madis. This has been an effective reason for the decline of the value added to the lands covered by Madis. Furthermore, studies show that improving the quality of Madis surrounding environment can induce the citizens to use these lands as green paths and memorable places for leisure times. Hence, using this green infrastructure to promote the less developed regions and reduce urban problems can be considered as a solution which is highly dependent on irrigation and water management and consequently the rights that are considered for Madis waters.  An effective factor in reducing the problems of modern cities is to use, regenerate and enhance green infrastructure to tackle the increasing problems of cities.
