One of the most important challenges facing urban management is informal housing. This phenomenon is one of the adverse consequences of urbanization in the contemporary world, which is especially formed as a result of rapid industrialization and regional inequalities, and due to the deprivation and lack of informal settlements in urban living facilities compared to other Urban areas have made them the focus of acute urban issues and problems and against sustainable human development. The current situation of informal settlements shows that the plans, forecasts and measures taken to address the problems of this phenomenon, especially in the metropolis of Tabriz, have not been so effective that the expansion of informal settlements in this city is a reason for this claim. For this purpose, in this study, an attempt has been made to systematically identify and analyze the key drivers affecting the formation and expansion of informal settlements in the Tabriz metropolis. The research method in the present study is mixed (quantitative-qualitative) with analytical-exploratory nature. The intersection of the components is formed. In the next step, the matrix is analyzed using Micmac software. The results of the dispersion of variables in the axis of influence and the influence of factors in Mikmak software indicate the instability of the system in the study area and accordingly, five categories of variables were identified. Finally, due to the high score of direct and indirect influence of factors, eighteen main factors were identified as key drivers in the formation and expansion of informal settlement in the region. Among the studied drivers, the variables of the economic sector had the greatest impact on the formation and expansion of informal settlement in the study area.

IntroductionIn recent decades, in parallel with theories of sustainable development and sustainable urban development, the idea of improving the quality of life, which in turn makes cities more livable, has found its place in urban planning literature and, therefore, the ability to have Livelihoods are essential for cities. This article has selected one of the most talented central cities of the country, namely Kashan city, as the scope of research, which has excellent features such as tourist attractions, historical and cultural history, natural attractions and so on. On the other hand, in this city, issues such as; Widespread unemployment and employment issues, the phenomenon of marginalization, lack of recreational and leisure facilities, high housing prices and rents, and so on. In order to eliminate these negative effects from the spaces of this city, it is necessary to identify and analyze the key factors affecting livability with a future research approach. The main question of the research is what are the key factors affecting the future situation of livability in Kashan?MethodologyThis research is based on the purpose of applied research and according to data collection methods, it is descriptive-analytical research and its data collection method is "documentary and field" in which the researcher-made questionnaire was used. The research method is based on the futures approach and its horizon is 1415. The statistical population was 15 experts and specialists. Futurism projects use a set of techniques and methods that often complement each other, and the outputs of each form the inputs to the next method. Micmac and Scenario Wizard futures software and Delphi method have been used to review and analyze the data. Propulsion forces are prioritized based on the opinion of specific experts and then these factors are prioritized based on the degree of importance and uncertainty, and the most critical factors are used to write down possible scenarios. Results and discussionIn this study, 24 factors were identified as effective factors of biodiversity indicators in Kashan. The identified factors are then analyzed with Mick Mac software to extract the main influential factors. The dimensions of the matrix were 24. 24. The degree of saturation of the matrix is 84.22%, which shows that the selected factors have a great and scattered effect on each other, and in fact, the system has been in a state of instability. According to Table 1, out of a total of 488 measurable relationships in this matrix, 88 were zero, which means that the factors did not affect each other or were not affected by each other.58 The relationship was one, meaning that the effect was relatively small. Together, 163 relationships were numbered 2, meaning that the influential interface was relatively strong, 174 relationships were 3, meaning that the key factor relationships were very large and highly effective. Finally, 93 relationships had a P number that indicated the potential and indirect relationships of the factors.ConclusionThe results of this study indicate 5 scenarios with different combinations of three situations, desirable, static and critical, which are likely to occur in the viability of Kashan city, which unfortunately, the probability of negative (critical) events is more than positive (desirable) events. However, 51.1% of the critical situation, 17.8% in the static state and 31.1% in the optimal state of the scenario page. With this situation, it seems that the favorable and stable conditions have occupied a smaller part of the scenario page and the critical situation is in the first priority and according to the results of these scenarios, it is clear that in Kashan's habitability, conditions are likely to occur. More critical, but less likely to occur. A very important point in the results is the relative distance of the level of desirability in the best case scenario with the ultimate living objectives of Kashan city. Assuming that the best scenario, which is Scenario 1, occurs among the five scenarios, it does not indicate the desired viability of Kashan in the future. In the most optimistic case scenario, one in four scenarios out of five scenarios affecting urban viability will be in an almost favorable situation, with only four desirable scenarios alone, and the other four scenarios have a much lower utility ratio. On the other hand, assuming that the worst possible situation, scenario 5, occurs in the viability of Kashan city, in this scenario we will see 6 critical situations in the scenario that we will not see a favorable situation in Kashan city.
