چکیده
ابرپروژه‌های شهری طی دو دهة اخیر در شهرهای بزرگ ایران از جمله شهر مشهد گسترش یافته‌اند. این پروژه‌ها که عمدتاً مبتنی بر رویکرد مشارکت بخش خصوصی و عمومی تعریف می‌شوند، در راستای تحریک توسعة شهر، ایجاد زیرساخت‌ها و تسهیلات نوین و برتر شهری و ارتقا جایگاه شهر تعریف می‌شوند. علی‌رغم آثار مثبتی که از این پروژه‌ها در حوزة برندسازی، ارتقای مکانی و اصالت‌بخشی گزارش شده است، این پروژه‌ها به دلیل تبعات مختلف اجتماعی، فرهنگی و حتی اقتصادی و محیطی با انتقادات گسترده‌ای روبه‌رو بوده‌اند. با توجه به تضاد نگرش‌های موجود، ارزیابی نحوة انطباق آن‌ها با اهداف توسعة پایدار ضرورت می‌یابد. این مقاله به ارزیابی سه نمونه از ابرپروژه‌های شهر مشهد شامل پروژة نوسازی مجد، نوسازی شهدا و توسعة منطقة گردشگری سپاد براساس ابعاد چهارگانة توسعة پایدار شامل شکوفایی اقتصادی، سرزندگی فرهنگی، ارتقای اجتماعی، تاب‌آوری زیست‌محیطی می‌پردازد. رویکرد پژوهش، به‌کارگیری روش نمونة مطالعاتی و نظرسنجی از طریق توزیع 387 پرسش‌نامه (بین کارشناسان مدیریت شهری، مالکین و بهره‌برداران مرتبط با پروژه) با پایایی 0.94 است. تحلیل نتایج با استفاده از تکنیک چرخه‌های پایداری، نشان داد که ابرپروژه‌های شهری در غالب شاخص‌های مدنظر برای پایداری به‌خصوص ابعاد اجتماعی و محیطی نامطلوب هستند. حجم بالای مهاجرت‌های ناخواسته، ناهماهنگی سازمانی و اداری در اجرای پروژه‌ها، کم‌توجهی و خوش‌بینی به مسائل فنی و مالی در اجرای پروژه و عدم توجه به خواست ساکنان، تقاضای بازار و طراحی پایدار از دلایل عدم موفقیت این پروژه‌ها است.

1. Introduction
Megaprojects as extensive investment projects are increasing recently in large and metropolitan cities in Iran. The projects, mostly based on public-private partnership, are defined to stimulate urban development or provide necessary facilities and infrastructure. They are considered as tools to promote the city conditions at national and international levels. However, some theorists argue the negative consequences of the projects while explaining the risky, problematic, and deceiving side of the megaprojects. Many megaprojects have been constructed in Mashhad. The city, as a destination for many pilgrims and tourists, and a hub for commercial and industrial activities in the east of Iran, has considerable potentials for development and competitiveness. Mashhad’s municipality encourages the urban projects based on public-private partnership in various ways due to its dependence on the revenues of construction work. While the projects are considered to provide better and modern services to facilitate, it seems that they have had a reverse effect by the saturation of built-up areas and commercial spaces in Mashhad. This paper tries to assess the effectiveness of megaprojects in Mashhad and their compatibility with urban context through sustainability assessment of the projects.
Megaprojects are considered as urban catalysts according to the neoliberalism ideology. The recent generation of the projects is mostly brownfield developments related to tourism and sport facilities based on the public-private partnership approach. The globalization, regional competitiveness, and privatization along with the technological improvement have led to the boom of mega and large-scale projects in cities.
Megaprojects may result in the provision of public spaces, services or infrastructure improvement. However, the economic prosperity which the projects usually seek are incompatible with the local economy and may hurt it. They also change the physical identity and the existing urban structure while damaging the social capital with social segregation and exclusion. In addition, compared to the normal projects, the projects have considerable environmental footprints.
2. Methodology
Focusing on megaprojects in Mashhad, the present study analyzes the effectiveness of megaprojects through the concept of sustainability circles. The concept assesses the sustainability through four dimensions: economic prosperity, social improvement, physical and cultural vitality, and environmental resiliency. The main approaches to the research are case study and survey. The case studies include large-scale renewal projects (Great Project of Shohada Square and Majd Project) and brownfield development (Sepad Tourism Zone). The survey which was administered to 387 persons including the experts, residents, and businesses in or surrounding the projects. Alpha Cronbach was used to test the reliability of the questionnaire. Based on the result of the coefficient (0.94), the questionnaire proved to be reliable.
3. Results
The results show the megaprojects in Mashhad are far from the sustainability concept in almost all aspects. All projects have not been satisfactory which it can be related to opposites of these projects with previous owners, residents and tenants of their fields. Majd and Shohada projects have been shaped in distressed areas. Thus, they destroyed the buildings, and they changed the urban structure, the place identity, and the urban spaces in order to build modern areas. Also, the projects led to a lot of commercial and office areas which are more than the city demands, so many of which are not strong enough to result in economic prosperity. Sepad, in its reproduction has created some picturesque architecture, commercial and recreational complexes, and related public spaces. It has also addressed the demands of general pilgrims and tourists of Mashhad through widespread advertisements to attract the people’s attention. Thus, Sepad has been more successful than other megaprojects regarding the economic and physical aspects.
4. Conclusions
Megaprojects in Mashhad are built to solve the challenges of distressed areas, mitigate traffic problems and provide modern services and infrastructure while they bring new challenges to the cities. The challenges could be related to the nature of megaprojects and their conflict with sustainable development to some extent. As the projects inherently seek for the place promotion and social improvement through the creation of new urban spaces and the attraction of the more affluent citizens, they may damage the historical identity and the social capitals as well. The projects include extensive environmental footprints and change in the urban ecological system. In addition, although the projects may promote some economic indexes of competitiveness, they may result in the degradation of the local economy which is relied on the urban assets and the residents’ skills.
Generally, megaprojects in Mashhad have not taken appropriate steps to economic prosperity, social improvement, place promotion, and environmental improvement. But, their wrong orientation and the lack of long-term vision in economic development have led to the saturation of commercial spaces and intensification of the building recession in Mashhad. The projects, also, delimit the probable trend of investment in other industries and entrepreneurship activities. In addition, although the projects have provided transit station, public parking, and streets, they put multiple pressure on urban networks, infrastructure including power, water, and sewage systems by overloading the built-up area.
In conclusion, megaprojects are inherently in conflict with sustainability and context-oriented development, especially, if they are defined based on an up-down decision-making process and lobbying exclusively between developers and urban managers.
There are forces in urban development arena that cause the continuation of megaprojects in large and even smaller cities in Iran. Therefore, the practical way to control and limit the forces and eliminate the negative impacts of megaprojects, would be the empowerment and legalization of the system of control along with supervising mega and large-scale urban projects. Using the sustainability factors, economic prosperity, physical and cultural vitality, social improvement, and environmental resiliency are recommended as the conditions for the approval of megaprojects.
