Background: The subject of the nature and management of conflicts in the literature of urban planning has a history almost as old as this discipline, and in recent decades, various schools of urban planning have reacted to this issue. The serious discussion about this issue started in the 70s and with the popularization of participatory planning in the 80s, it has grown significantly and has been discussed in the world literature. The positions presented so far regarding the understanding of conflicts in planning are an incoherent and sometimes opposite set based on various theoretical-philosophical bases. In order to obtain a criterion for understanding conflict and conflict management in urban planning, according to the historical development of the engagement of planning theory with conflicts, this study has classified the viewpoints based on the prevailing theoretical-philosophical and contextual approaches. Filling this gap requires an answer to the question that each of the presented views of conflicts in planning is based on what theoretical or contextual approach?
Objectives: Description and understanding of conflict and conflict management in the context of urban planning and classification of this issue based on the evolution of planning theories over time.
Method: The methodology is based on meta-analysis and qualitative content analysis, and a systematic review in the Scopus and Google Scholar database and in the PRISMA framework was used to collect data. According to this framework, the content analysis of 183 English sources was done.
Result: The positions surrounding conflicts in urban planning can be considered as "managerial", "theoretical" and "situational" approaches. The situated approach includes conflicts in the fields of "spatial-locational patterns of the city", "land use and ownership", "urban development and regeneration", "Urban spaces" and "large-scale projects". The managerial approach includes "decision-making process", "conflict management techniques", "impact assessment" and "institutional analysis and design" and the theoretical approach includes "the role of planning theory", "the role of power institutions" and "the role of the planner" in understanding the problem of conflict. Management and theoretical approaches based on the historical course of understanding conflicts in the field of urban planning theories can be recognized in three paradigms: "positivist" with the belief in guided consensus, "post-positivist" with the belief in the end of conflicts through consensus based on discourse ethics and "critical" By emphasizing the hegemony resulting from consensus building and the constant reproduction of conflicts in planning.
Conclusion: Despite the ideological backgrounds and different approaches to the conflict, a political turn in this field is understood in the theory and practice of urban planning. Therefore, in this field, planners should go beyond the traditional relegation of their actions to a regulatory dimension and help to reconceptualize urban policy and transform the physical and symbolic dimensions of space.

Highlights In the process of urban regeneration, the establishment and strengthening of decision-making should be through evaluation. The article has tried to achieve a generalizable structure for evaluation after the implementation of flagship development at neighborhood scale. In flagship development at the scale of neighborhood, more important notice should be given to the residential parameter. Introduction. Urban development through development of internal neighborhoods is an attempt to restore urban life to the deteriorated areas of cities. In order to facilitate this process, planning and implementation of flagship development has been considered as one of the policies used for urban neighborhood regeneration and provision of the requirements for the residents’ presence and concern for different dimensions of development.Regeneration of the historical and deteriorated areas in cities has been addressed in the recent literature on urban planning worldwide. Inefficiency is a major problem in historical and deteriorated urban areas, where automatic update and change is no longer possible.As in many other countries, the current process of extension of deteriorated urban areas in Iran indicates that problems will be complicated if no precautionary measures are taken, and no appropriate policies or operating plans are adopted.Implementation of flagship development has been considered as a solution.A main purpose of flagship development is to help achieve urban regeneration goals, an approach taken up as a comprehensive strategy for making positive changes in a place with signs of deterioration. This strategy is aimed at quality improvement, with integrated economic, social, and physical goals. Flagship development is applied in order to improve a place that is in the process of decaying and deteriorating, and its advocatesare agreed that an urban area will not achieve regeneration without such projects, since it causes a series of reactions that will lead to regeneration of the urban fabric. On the other hand, it is not the case that we hope to achieve development over a vast urban area simply by relying on this project, as many projects all around the world have failed to achieve their main purpose, i.e. to regenerate a decaying fabric. Theoretical Framework. Evaluation is possible throughout the urban regeneration process, from the stage of problem identification to the implementation of projects and the review of the decision-making process. Through presentation of mobility and development indicators, therefore, the present study has developed into an appropriate, generalizable structure for assessment of the impact of flagship development and catalyst projects after implementation at the neighborhood scale. It evaluates the effects of an example of these projects in the Gowdal Mosalla neighborhood in the historical city of Yazd, Iran. The theoretical framework of the research involves three main parameters based on the overall literature and practical experience: the physical parameter, the residential parameter, and the activity parameter. The activity parameter includes the indicators of dependency burden, percentage of active population, percentage of commercial use, active commercial use, employment rate, and men’s rate of immigration. The physical parameter includes the indicators of access to infrastructure, access to parking space, population density, residential renovation, percentage of non-arid land, sustainable buildings, new buildings, percentage of administrative use. The residential parameter includes the indicators of percentage of indigenous population, percentage of tenancy, active housing, single-family housing, home access to primary schools, access to local parks, access to sports venues, youth population, number of students, level of education, and coefficient of residence. Methodology. A research method based on the quantitative methodology, regression analysis was used in this study to analyze the effects of each indicator on each factor, and the matrix of impact assessment, known as Leopold Matrix, was used for evaluation after the implementation of the flagship development and the neighborhood regeneration. The final results were obtained after 25 evaluation indicators pertaining to urban regeneration and flagship development were extracted from the established overall literature and practical experience, and secondary data on 93 urban blocks of the Gowdal Mosalla neighborhood were analyzed in SPSS 21. Results and Discussion. The research findings demonstrate that the project performed at the Faculty of Arts and Architecture of Yazd has the greatest effects on the physical parameter, followed by the residential parameter and, eventually, the activity parameter at the scale of the Gowdal Mosalla neighborhood, and it can be approved as a positive flagship development through provision of modification options. The results indicate the closest relationships between the indicator of native quality and the residential status of the fabric, between the indicator of access to services and the status of the residential environment, and between the indicators of population at the age of activity and percentage of commercial land use and the activity and economic status of the neighborhood. Population density, administrative level, and the stability of buildings affect the mobility and physical development of the neighborhood. Conclusion. In future planning, it is necessary to consider indicators that focus on improvement of the residential parameter, especially through consolidation of the existing indigenous population and absorption of the young population. Moreover, the extracted theoretical framework will be effective for planning flagship developments and evaluating them in future practice and research.
