This paper is intended to assess the developments conducted on the master plan of Old Najaf, mainly in three areas: the Imam Ali Holy Shrine and its surroundings, the Great Market Area and the location of the Town of Visitors.

In order to analyse the implementation of the transformation phases in Old Najaf, the Strengths, Weaknesses, Opportunities, and Threats (SWOT) technique was used to identify and organise the strengths, weaknesses, opportunities and threats related to the examined case study of the city's historic centre. At the first stage, all available data (photographs, maps, documents and reports) were collected from different sources, including previous studies by governmental institutions, departments and agencies. Ultimately, the SWOT analysis was used for each identified phase in the morphological evolution of the historic centre. This can offer an opportunity to observe the implications of urban planning practices in Old Najaf from the mid-20th century to the present day. In order to identify the well-organised urban design practices and appropriate strategies, the implemented studies and projects were examined by the four factors of the SWOT analysis.

The current results have revealed important urban transformations, already made and/or ongoing, of those aforementioned three main areas, which imply a great loss of the city's traditional character and urban heritage. Further, the environmental and socio-economic issues should be involved in the analysis to evaluate how they have influenced the current outcomes of Old Najaf in relation to the urban configuration and orientation.

The rich cultural and architectural heritage of Al-Najaf historic centre is dramatically neglected and seriously threatened to be lost. Hence, conservation on both tangible and intangible levels is urgently needed. It is the first paper which focussed on this problem and tries to learn from the British Conservation Experiences in this field.

The objective of this paper is mainly to contribute to and activate, the process of saving and preserving the rich tangible and intangible heritage embraced in the historic center of Al-Najaf city. This was possible through examining the existing historic urban and architectural structures of the city, unveiling the major issues that are threatening both its traditional cultural and architectural identity, and finally analyzing similar examples that proved to be successful in addressing similar problems in order to derive possible strategies for saving, preserving and revitalizing the historical center of Al-Najaf Old City.

This paper addresses the major problems of heritage preservation in Al-Najaf City (750 AD), which is one of the historical and most sacred religious centers especially for Shia Muslims around the world. Despite its importance, the rich cultural and architectural heritage of the city is dramatically neglected and seriously threatened to be lost.

Preservation in Al-Najaf City is proposed as a sustainable development strategy. Top-down and bottom-up strategies are proposed not only for preserving the historic architectural and urban characteristics of the city but also for reviving its social and cultural activities and traditions.

The major issues addressed in this paper include the fragmentation and decentralization of the cohesive traditional urban fabric, the disruption of the spatial organization, the deformation of the traditional architectural characteristics of the city and its skyline, the discontinuity of facades' patterns, the destruction and demolition of historical buildings, the transformation of land use, and the regression of traditional social and cultural activities.

The purpose of this study is for a higer sustainability of the historic towns and centres. The task of the society is to minimize risk and guarantee maximun safety within the territory while safeguarding the natural as the built landscape. With these sometimes unfortunate outcomes in mind, the society continue to promote “informed planning” hoping to achieve ever grater sustainability and respect for the extant, but, in practice, what the society have done amounts to very little. Indeed, today’s historic city centrers remain neglected and are increasingly “unsafe”.

In the course, Italy introduced a set of regulations in an attempt to construct, transform, conserve and exploit the potential of historic cities. Unfortunately, the results were not outstanding and today we need to rethink their approach if we are to reverse the abandonment of historic centers and make those “safe” again. In an effort to understand if what was hitherto put in place is sufficient or if new strategies are called for, we have reviewed the technical measures issued. In a large number of cases, restoration only increased their fragility, whereas in many others, especially concerning small centers with traditional economies, no rehabilitation work was ever attempted, not even essential maintenance work, and thus their functional and physical obsolescence became manifest.

The variegated and complex fragility of such centers requires forms of planning that can take account of the environment, deploy city-planning measures and undertake structural and architectural adaptation. If regeneration is to lead to a “comprehensive and integrated vision” for solving urban problems, economic, physical and social improvement and appropriate environmental conditions for an area subject to transformation, it will require new national and local action policies able to guarantee physical safety, the conservation of cultural values and the social and economic regeneration of such centers within a framework of policies for equilibrated urban development.

The processes of repurposing/revamping and giving leverage to historic centers must make use of multidisciplinary approaches ranging from conservation needs to overall regeneration needs. Therefore, new formulas are needed to enable us to combine conservation based on protective constraints with formulas for rehabilitation, reuse and performance improvement that are couched less in terms of sustainability, and more in terms of profitability, according to the principle – repeatedly voiced in international forums – that assets are also economic resources. Therefore, it will be necessary to proceed carefully, by drawing up a program of territorial development strategies with due guarantees of feasibility and economic growth prospects.

An appropriate regulatory framework is certainly necessary for the regeneration of historic towns and centers but an even more important role should be played by projects that optimize the use of resources if we are to ensure that financing will be managed correctly and a connection will be created – given the discontinuity represented by new constructions – between what remains of extant historic and contemporary architecture and construction. In this context, contemporary architectural design and urban planning can help meet the continued requests for the refurbishment of consolidated cities and the reconstruction of earthquake-stricken towns.

Rehabilitating center is not a cultural luxury but a necessity that springs from the need to economize territorial and economic resources. Consequently, a methodology should be formulated to produce, in each specific case, a design jointly drawn up by town planners, architects, urban redevelopment experts, structural engineers and with the participation of many other specialist figures, such as economists, sociologists, geologists and engineering physicists.

This paper provides a multidisciplinary vision on regeneration.

In last year, the innovations in shipbuilding and logistics have opened the walled towns of Mediterranean port cities to cruise tourism and other culture-led regeneration strategies. Thus, walled towns in Mediterranean port cities have a particular development potential which questions about the opportunities and risks connected to any comprehensive regeneration strategy with a cultural and tourist purpose, especially for fortified systems whose continuity has been undermined. The paper aims to provide some guidelines for policy-makers and planners in port cities which have decided or are deciding to develop a comprehensive strategy and a knowledge framework for the walled town similar to those already adopted for fortified sites in the World Heritage List.

The paper investigates on the opportunities and risks connected to any comprehensive regeneration strategy with a cultural and tourist purpose for the walled towns through a comparative analysis of four Mediterranean seaport cities, selected as case studies. Cities which have developed an integrated strategy to inscribe their walled towns to the UNESCO’s World Heritage List.

On the base of the case studies’ analysis, the paper proposes a critical reflection upon the management strategies for the UNESCO’s walled towns and supports a better understating of context factors as a way to strengthen the HUL approach when applied to Mediterranean seaport cities.

The paper sheds light on the application of the historic urban landscape approach to the walled towns of Mediterranean seaport cities. The paper is original because it provides: guidelines for policy-makers and planners in walled towns of Mediterranean seaport cities which have decided or are deciding to develop a comprehensive regeneration strategy for the city centre in line with those adopted in UNESCO’s fortified sites; a critical reflection upon the context factors which can strengthen the HUL approach when applied to Mediterranean seaport cities; criteria to update the HUL approach by UNESCO in analysing the conservation state, the managerial aspects, the participation and social aspects of walled towns.

Five-footways are an important feature in historical urban centres of tropical South East Asian cities. These colonnades along the rows of commercial shop houses provide comfortable pedestrian walkways. In spite of the decline of the liveability in many historical urban centres, the “kaki-lima” or five-footways in Klang Valley Malaysia are bustling and alive. Many studies have been done on kaki-lima, however it focuses mostly on historical and cultural context. There is lack of understanding on how the physical attributes of kaki-lima facilitate the liveliness of urban life. The paper aims to investigate the five-footway as the generator of public realm and to analyse the physical attributes of the five-footways that contribute to the “stickiness” of the public space.

The study utilized behaviour mapping to identify the sticky activity, then subsequently used Roger Barker's theory of Behaviour Settings to observe different stationary activities along the five-footways of the historical centres of Kuala Lumpur and Klang.

The findings show that all the identified behaviour settings along the five-footways are strongly characterised by tropical climate and local diverse culture. Additionally, the small architectural detail provides an important physical setting for informal activities to take a place in the five-footways.

The study is limited only to two urban heritage districts in Malaysia, namely Kuala Lumpur and Klang.

The findings have the implication for the public space policy of the local municipalities, specifically for urban design policy of the five-footways. Firstly, the inclusion of five-footways should be encouraged in any new shophouse development and secondly, the policy maker should consider to retain certain physical features of the five-footways that support not only the informal economy activities but also the creation of third places in the neighbourhoods.

This study will contribute to the discourse of urbanism, especially in understanding the public realm in South East Asian cities. Additionally, the outcomes will assist the local municipality in developing urban design policy of the five-footways.

The UNESCO recommendation under the historic urban landscapes (HUL) title and Operational Guidelines (OPG) were used to create dynamic protective boundaries to maintain the integrity and authenticity of Isfahan's heritage waterways. Accordingly, by using GIS and Isfahan urban layers, three protective zones were proposed and evaluated; the central zone, the functional zone and the visual zone.

Heritage waterways in historic cities are not adequately protected against the negative impacts of urban development, and there is a lack of a dynamic protective system to protect their integrity and authenticity. The problem can be observed in Isfahan, a historic Iranian city, where the boundaries of urban heritage waterways (Madi canals) are usually rigid and arbitrary. This study aims to develop a practicable paradigm for determining protection boundaries for Isfahan's Jolfa Madi, an urban heritage waterway.

Compared to the current protective boundaries, the authors found that proposed protective boundaries create a greater amount of protection space, which makes a strong connection among the ecological, historical and socio-economic characteristics of the urban context. Furthermore, the protective zones based on the HUL approach give Isfahan's urban planning policy the opportunity to consider participatory tools, financial tools and regulatory systems.

Many studies have emphasized a fixed-width buffer or an arbitrary distance from the urban waterway's axis (urban heritage) or its banks. Although these protections include technical conservation or setting restrictions on the adjacent buildings and blocks, studying crucial concepts such as urban dynamic, urban heritage context and producing a particular technique for protected boundaries has not been investigated. In this article three dynamic boundaries are delineated with various functions in order to provide urban heritage with dynamic preservation and sustainable development for the historic urban landscapes.

Despite various comparative studies in the field of cultural heritage protection in the world, there is still a significant lack of comparative research on policies related to the legal system of countries' governance. The purpose of this study is to address the comparative policies in Iran and Italy, with a particular focus on the results of the executive experiences of two different types of policies in the cities of Oroumieh (North-West of Iran) and Turin (in North-West of Italy).

Utilising the comparative, analytical, bibliographic and descriptive historical research methodology, which is based on the study of the local, national and international comprehensive review of regulations and policy-making of cultural heritage preservation policies in Iran and Italy. In this research, the related documents in three languages (Persian, Italian and English) have been examined to compare profoundly and comprehensively the policies and regulations adopted in these two countries to be able to analyze the national and transnational regulations and local policies in the cultural heritage sector.

In addition to many cultural similarities and numerous commonalities, especially in the multiplicity of urban cultural heritage in historical centers, the results suggest that the legislation structure in Iran is much more centralized than in Italy. Also, the findings suggest that Italy focuses on aligning its previously centralized national legislative system in line with contemporary European heritage and preservation policies.

The paper outlines how to use historical and cultural similarities through comparative study to benefit the experiences of two historical countries in urban heritage conservation and policy-making part despite their differences.

The preservation of historic urban centres prevents anarchic development of the city and ensures a harmonious evolution of the urban form. It also improves the quality of life in the context of climate and environmental change. Morphological and geometric indicators of the urban fabric are key parameters in the formation of external microclimates. They provide a positive effect on the thermal comfort of pedestrians. The objective of this work is to study the impact of the site morphology on the external microclimate and to understand the relationship between the subjective perception and the objective quantification of the thermal environment. The result of this study has allowed us to propose solutions for the creation of a microclimate favourable to the appropriation of outdoor spaces. The authors finally propose guidelines for the design and rehabilitation of the historic site based on the establishment of links between the site's configuration, microclimatic conditions and users' perceptions.

Part of this study included the analysis of the microclimate of the historic “Bab El Hadid” district of the City of Tlemcen, by developing a questionnaire survey and a numerical simulation validated by measurements of the microclimate the authors made on site. To complete this task, the authors applied the Envi-met 4.1 model during the coldest month of the winter and the hottest month of the summer. Urban parameters are represented at different measurement points characterised by a variability of the sky view factor (SVF).

The results presented in terms of average expected the predicted mean vote (PMV) voting, solar access and air temperature. They show that thermal conditions are directly related to the SVF, the height/width ratio (H/L) of streets as well as the orientation of urban canyons. The points located in the streets facing North–South, present an acceptable performance. Streets shaded by trees with a canyon aspect ratio of between 1.18 and 1.70 reduce heat stress in outdoor spaces. The PMV models discussed provide information on the most appropriate locations for pedestrians. The authors have proposed urban orientations that could limit unfavourable conditions in outdoor spaces. They are useful for architects and urban planners in the design and rehabilitation of historic centres.

In Tlemcen, the microclimate is not taken into account in the design and rehabilitation of urban fabrics. For this specific purpose, the authors want to stress in the research the importance of safeguarding urban heritage through the renewal of the old city and the bioclimatic rehabilitation of its urban spaces.

The purpose of this paper is to investigate the effect of different levels of place understanding (primarily typo-morphological analysis) on the nature of interventions within historic urban setting and buildings within the City of Amman.

The research methodology depended on an extensive thematic survey and analysis. The typo-morphological analysis addressed several of Amman's residential hills and their connections with the downtown area. The thematic place survey tool included different units of analysis (e.g. buildings, public spaces, streets and sloped lands between streets) and addressed the values of these various buildings and spaces, their typology, typo-morphology and relation to the urban context, nature of change and transformations over time to mention a few. The extensive survey also included semi-structured interviews about these buildings addressing their emergence, historic context and values.

The paper presents an architectural typology for Amman's architecture and its relationship with the city's morphology stressing the specificity of Amman's historic core and residential hills. The paper also discusses the effect of this level of place understanding on the nature and levels of interventions within historic settings and buildings.

This level of place understanding (typo-morphological analysis) can have a positive impact on the practice of architectural and urban conservation by informing the nature of interventions within historic urban setting and buildings within the city. More specifically, this level of place understanding can, first, inform the development of urban and heritage guidelines within conservation areas in one of Amman's residential neighborhoods (Weibdeh) and, second, inform the nature of interventions to existing historic buildings based on respect of building typology.

This paper contributes to the disciplines of architectural and urban conservation illustrating how place understanding can inform practices of heritage conservation and future policies and strategies concerning new intervention within such heritage places.

Over the last two decades the United Arab Emirates (UAE) have been actively restoring their modest urban heritage. However, conservation actions are not streamlined within the country and there is no legislation to protect this heritage. A number of European experts have been invited to carry out studies, but the extent of this involvement has not been clear.

To illustrate this, conservation interventions in specific urban and architectural heritage sites, namely Al Bastakia in Dubai and Al Merraija in Sharjah, were examined.

First, this paper discusses conservation philosophy, meanings and practices. This is to assist understanding of the broader conservation issues affecting urban and architectural heritage in the UAE. Then, it presents historical accounts of architectural and urban heritage practices in Dubai and Sharjah. Finally, conservation approaches implemented over the last two decades within the two historic sites are compared and evaluated.
