The inclusion of historical cities in the world heritage list provides a significant advantage in demonstrating these cultural monuments on a national and international scale. It is only natural for all countries to strive for the registration of their historical and cultural landmarks on this prestigious list. However, the crucial question arises: does registration on the World Heritage List mark the culmination of efforts, or does it signify the commencement of a more critical mission focused on preserving the original and significant values of these sites, which have developed and flourished within their cultural and social contexts over time? It is evident that the establishment of a comprehensive work management program post-global registration, along with the monitoring of its implementation, holds paramount importance. This significance is heightened when considering cities and their historical textures; cities serve as the stage for the interaction and confrontation of the physical elements of the urban landscape with the social dimensions of human life, the natural components of the environment, and the artificial aspects of the surroundings, encapsulating human presence across psychological, social, economic, cultural, aesthetic, and other realms. Therefore, any decision aimed at enhancing the state of a city must prioritize the human element as the most crucial factor, underscoring the significance of non-physical aspects in the rejuvenation of historical cities. Furthermore, what becomes apparent in historical textures and their restoration post-registration on national and world heritage lists is the fulfillment of responsibilities by urban authorities. This implies that programs following the registration of sites often exhibit several characteristics; they do not ensure the desired outcomes, lack a holistic approach to restoration and revitalization in their development and formulation, and are devoid of adequate organizational backing or continuous monitoring and refinement.
Hence, in general, the acceleration of changes and sometimes damage to historical structures occurs after their registration. The city of Yazd is no exception to this phenomenon, as the changes following the world registration of its texture have been rapid, uncontrolled, and emotionally driven, resulting in incorrect interventions. The unregulated and indiscriminate presence of tourists has also had a detrimental impact on the local way of life. Additionally, the creation of added value through real estate disposal has significantly reduced the occupancy rate in this area. The conversion of small urban units into non-authentic uses has further eroded the authenticity and integrity of the texture, while physical interventions in passages and arteries have transformed this area from a historical axis into a display of light, patterns, and designs, with the original life becoming less visible, if not completely absent. However, according to the accepted principles of restoration, the preservation of the identity and original nature of the texture is the foremost and most crucial aspect. 
This preservation should encompass economic, social, cultural, anthropological, physical, and functional considerations. Any violation of this important principle during the registration process, after it, or during the revitalization of the affected texture would result in damage and complications. Moreover, the purpose of registering any work is to show its unique characteristics to the world. If this registration leads to the weakening of these values, it fundamentally contradicts the purpose and not only fails to contribute to the revival of the texture but also causes irreparable harm in the long term.
 
Introduction
The historical texture of Yazd was officially registered as a world heritage on July 18, 2017, during the 41st meeting of the World Heritage Committee of UNESCO in Krakow, Poland. The process of world registration for Yazd began in 2010 and was solidified in 2015. The "Comprehensive Protection Plan of Yazd Historical Texture," established in 2008, played a crucial role in the preparation of the city's world registration file. It is important to note the emphasis placed on social values, local community, native architecture, and urban planning in the historical texture of Yazd. However, more than a decade after its world registration, there seems to be a lack of consistency in implementing plans to preserve the local, urban, and national values associated with this world heritage site. 
These capabilities, encompassing both tangible and intangible values, hold great significance as they serve as the primary motivation and means to preserve and perpetuate all cultural heritages, including historical textures. These values can be found either overtly or covertly within them. The correct social relations, specific spatial relations, organic development of the texture, population composition, diversity of generations and racial composition, and above all, the natural flow of residents' lives, are among the most crucial values and prevailing norms within the historical texture of Yazd. Together with numerous other factors, these values have shaped the texture of the city. Now, the question arises: How does the world registration of a historical texture or heritage site, along with its associated policies and management, strengthen or weaken the values within the site? Does the mere registration of a site on the World Heritage list imply protection? Does it have any impact? The global registration of a site is just one part of the overall process of protecting the site. What steps should be taken after registration? In this article, based on field observations, we aim to provide a concise analysis of the state of the historical texture of the city following its global registration, and the objective changes that have occurred by accepted preservation guidelines. While our intention is not to provide specific conservation solutions, our analysis, based on a conservation pathology approach, can help identify the underlying principles for effective conservation strategies and prevent the transformation of the historical texture and its inherent values.
 
Conclusion
The inclusion of a world heritage list for historical textures is a positive step towards bringing attention to them on a national and international scale. However, it should not be viewed as the ultimate objective. Rather, the completion of the world registration process should mark the commencement of strategic, well-informed, and scientifically-driven management planning that considers all facets of the texture, both tangible and intangible. This management plan must be designed with short-term, medium-term, and long-term goals in mind, grounded in practicality rather than unrealistic aspirations. It is essential to establish specific administrative bodies tasked with defining and overseeing activities to ensure effective implementation.
Periodically, the outcomes of the interventions are evaluated, focusing on physical, cultural, and social impacts. Potential shortcomings and strengths of the plans are identified, leading to adjustments in the management plan for the subsequent phases. Disregarding the involvement of the local community is the most significant drawback of such initiatives. Without fostering civic engagement among the locals, the projects are bound to fail. Moreover, if the community does not comprehend the objectives and initiatives based on their perspectives and requirements, their participation will be minimal.
