In the context of Hamadan, recognized as a significant new urban center in the country, substantial challenges in urban management processes have emerged, encompassing both organizational and external dimensions. Recent years have witnessed mismanagement in service delivery, spatial injustices, physical-spatial disparities, lack of transparency in presenting plans and programs, and an increase in civic problems, exacerbating issues within the city. This complex scenario has the potential to escalate into serious regional crises. Acknowledging the urgency of addressing this matter and emphasizing the need for regional studies, the present research investigates the indicators of good governance in Hamadan, categorized by different regions. Employing a descriptive-analytical approach and utilizing a quantitative method, the study involves experts from the Hamadan management team, with a sample size of 35 individuals. The research findings, analyzed through average test models in SPSS software and the TOPSIS multi-criteria decision-making model in MATLAB software, reveal that the good governance indicators in Hamadan are not in a desirable state, particularly with districts 3 and 2 facing severe deficiencies in urban governance indicators.

Urban spatial expansion is the result of urbanization's control over the geographical space and it represents the process of land conversion to urban uses. The new trends of spatial expansion, especially in developing countries, are pregnant with numerous social, economic and environmental challenges, and forcasting the spatial expansion challenges is one of the useful methods for finding a sustainable spatial development strategy.The current research is a type of applied-developmental research that was carried out using a qualitative-quantitative method. In the qualitative part of Delphi group decision-making method, the opinion of experts regarding the identification, summarization and comparison of two indicators has been done, and in the quantitative part, the data has been analyzed using Interpretive Structural Modeling (ISM) in Micmac software.The findings of the research show that for internal migrations, population imbalance in the territory, instability of the settlement system, weak legal control, distribution of injustice, foreign migrations, social instability, poverty, destruction of the rural way of life, marginalization, increase in crime rate and Delinquency, poor social control, critical burden of the population, abnormal housing and the decline in the quality of life have the greatest influence and will play a role as the first level of challenging factors in the future of the metropolitan area of Tehran.The results of examining the challenges of the metropolitan area of Tehran show that among the components examined in the metropolitan area of Tehran, the highest level of influence and  is related to the migration component with an influence of 107.5, and this component is the most challenging factor in the future of the metropolitan area of Tehran. will work, and the lowest power of influence and influence is related to the component of annexation, integration and depopulation of villages (with influence power of 67.8).

Human settlements (especially urban ones) face a wide range of challenges in connection with the natural world. These challenges are essential for the well-being of citizens within the framework of three pillars of sustainability, namely environmental, social and economic, and five vital dimensions; People, planet earth, prosperity, peace and participation are important concepts of sustainable development goals. The new UN Urban Agenda proposes a paradigm shift based on urban science and sets standards and principles for the planning, construction, development, management and improvement of urban areas along its five main pillars: urban policies, laws and regulations, Plans urban planning and design, local economy and municipal finance, and local management. The Covid-19 pandemic affected life around the world. This pandemic has caused many fluctuations in the viability index of urban settlements. It has also affected the way people interact and use public open space in cities around the world. Other effects include increased stress, depression and mental illness in urban areas around the world. In this article, while expressing the challenges of urban settlements, especially in the era of the Covid-19 pandemic, and the effects it has on the livability of cities, the human-centered planning and design approach to future cities within the restorative city in the face of the effects of this pandemic is discussed.

Today, one of the important urban challenges is undesirable parks site selection that pay attention to this factor can be Promote Livability and Vitality in urban space. The purpose of this study is assessment Affecting Factors on urban park site selecting and Its Optimal Site Selection due to lack of them. Analytical Research method is Descriptive and Analytical methods with an emphasis on practical aspects. So classify and analyze the data, Analytical Hierarchy Process and Analytic Network Models, is used. For weighting layers used, 10 experts, professors and urban planning opinions. This research after the distribution of existing parks And determine the radius of standard performance using network analysis that 53/18 percent of the city area are beyond access to parks The criteria consistent, inconsistent, population density and a key communications network for locating, as the main criteria considered in the optimal location That in Incompatible layers Distance from existing parks whit Coefficient 0/598 Rated first The compatibility layer as well as access to culture land use whit Coefficient 0/600 Rated first. And final weight criteria was calculated by using network analysis model also that the population density layer whit Coefficient 0/395 Rated Second place and Compatible layers whit Coefficient 0/300 Rated Second place. Finally, according to the present investigation by combining several layers of impressive land uses the final map of the optimal areas in five categories from compatible to incompatible divided. 117/39 Hectare of the land city is compatible for construction of new parks.
