Importance of climate change is global. This issue to some extent has been out of human control. Human beings can only provide security and the community with knowledge and management against its negative consequences. On the basis of this research, the present paper analyzes the impact of climate change on Iran, on a small scale and applied to the central catchment area. The findings of the research indicate that climate change has shown the geographic region of Iran in terms of changing the rainfall pattern, decreasing precipitation and increasing its temperature. In the next step, these cases resulted in excessive withdrawal of groundwater aquifers and it has reduced the quality of underground water. This chain has led to the design of inter-basin water transmission projects, which is at least the result of the cycle of social tensions that has occurred in recent years. Considering the geographical extent of the basin and its belonging to one of the most frequent aspects of Iran's civilization, the set of consequences of climate change in the central catchment area, in addition to its impact on various social, political, economic and environmental layers, also has several scale effects. And its destructive effects go beyond national scale and to an extent beyond the scope of Iranian culture. In this regard, the research findings indicate that climate change in the central watershed is influential in many aspects of society and the country, so that if the current process continues, the current Iranian civilization will face a strategic challenge. To this end, at the end of the research, good water governance, as the best way to confront and control the negative consequences of climate change on the central catchment area, and Iran in general, has been argued.

Tehran metropolitan authorities have always tried to develop the most efficient model for managing Tehran metropolitan affairs. Currently, the Tehran city management model is the council-city model, according to which people elect the members of the city council by direct vote, and the Tehran City Council elects the mayor. Over the past years, and considering that the institutions and organizations in charge of managing and providing urban services have in some cases suffered from parallel work or even inconsistencies in tasks, there is a need to develop a model for integrated urban management. In this article, descriptive-analytical method has been used. This article is practical in terms of the purpose of the study. The purpose of this article is to achieve a model for integrated management of Tehran metropolis. The statistical population of this study is Tehran urban management experts for which 34 people were selected as a sample. The data collection tools of this research are interviews and questionnaires and the data have been analyzed using paired comparison and TOPSIS methods. As a result of this research, according to the identified challenges and using TOPSIS method, the efficiency of the developed research model (with the proposed name of service desk) compared to the current model of Tehran urban management has been confirmed. Also, the most important result obtained from comparative studies is that in the studied metropolises, all matters of governance and urban management are always under the command of one institution and parallel work has been avoided, which should also be considered in Tehran.

The Urban Development Strategy Plan is an attempt to take into account the potential and talent capacities of the city in an institutionalized and systematic framework and the construction of a clear future as one of the current concerns that identifies strategies for creating urban sustainability conditions in good governance. The main idea of ​​this policy is that it is imperative for all cities in an increasingly competitive and increasingly global economy to have a clever and clear strategy for how its land is positioned to minimize negative effects, predict potential shocks, and exploit the comparative potential and Competitive In such a situation, making decisions for urban issues and planning for the future is much more difficult. The purpose of this study is to evaluate the urban development strategy of District 22 as one of the tools for implementing urban governance paradigm. The research method is descriptive-analytic. The tool for evaluating AHP's hierarchical analysis technique is implemented according to the views of the experts and stakeholders. The results of the research indicate a significant difference between the design of CDS and its implementation phase.

 The purpose of this study was to develop good governance indicators and criteria, evaluate good governance in integrated management of Kish, and provide strategies to promote integrated management of coastal areas with good governance approach. To accomplish these goals, firstly, by explaining the subject literature and reviewing the research background, an integrated coastal zone management model with a good governance approach was presented. The main criteria in this model are participation, legislation, accountability, accountability, central justice, transparency, efficiency and effectiveness, and community-centricity, each of which includes sub-criteria. Then, by using questionnaire and interviewing residents and experts, as well as by applying hierarchical analysis method, good governance status in integrated management of Kish was assessed. The final score of Kish by calculations was 2.53 (out of 5), indicating a relatively inadequate situation of good governance in Kish integrated management. Finally, solutions were presented to promote good governance in the integrated management of
