There are some environmentally critical areas (ECAs) in cities such as flood flow areas, agricultural land, canals, rivers, water bodies, forests and hills that need to be conserved from land transformation. The purpose of this paper is to review the compliance, challenges and significance of urban planning, and to develop a contextual framework of urban planning for environmental area conservation to improve the urban environment in case study city Dhaka, the capital of Bangladesh.

This research is based on a qualitative thematic analysis of the available relevant literature.

This research identified non-compliance of the contemporary urban plans such as indiscriminate land conversion activities in the ECAs. Conflicting interests between the urban plans concerning protection of the conservation areas and business interests of the community people and the real estate development companies are identified as the major challenges. Dhaka faces several environmental problems such as loss of biodiversity and ecosystem, waterlogging, flooding, pollution, reduction of vegetation, groundwater depletion, temperature increase and a reduction in agriculture and fishing because of land conversion in the ECAs.

Urban planning with effective conservation area management, conflict resolution through communication and participation, creation of economic opportunity to generate income from the ECAs and assessment of the conservation strategies and interventions might ensure environmental conservation in Dhaka.

The conceptual framework of urban planning for environmental conservation is innovative as this could be a basis for other cities in Bangladesh and in other developing countries.

Urban conservation is an integral part of urban development planning and it is incorporated into land use rules and plans. In order to achieve the goals of an ideal heritage conservation policy, there are spatial plans, building codes and relevant regulations that should be well prepared as reference for development projects. Kota Lama Semarang (Old City of Semarang) area has been recognized as part of the origin of the development of Semarang City, the capital city of Central Java. This area has been designated as a cultural heritage area both at the city and national level since 2020. The Heritage City Conservation Program (P3KP) encourages Kota Lama Semarang Area to experience fairly massive development since 2013. On one hand, to control and manage the area, the Semarang City Government issued several official planning documents, i.e. (a) Kota Lama Semarang Area RTBL documents (2003); (b) Kota Lama Semarang Grand Design (2011); and (c) Kota Lama Semarang Site RTBL (2020), which consecutively were used as references of development projects. On the other hand, the results of development projects indicated that there are no coherent physical improvements in the area. The study was conducted to show whether there are consistencies or mismatches between the three planning documents.

This study used a qualitative deductive method with content analysis technique to compare three planning documents, using the predetermined variables.

The results showed that the consistency between the three planning documents was not fully demonstrated, but they are mutually interconnected.

The research focused only on three formal planning documents, for which comparative analysis was undertaken using content analysis to identify consistencies and inconsistencies based on determined 9 variables.

Good planning documents should be consistent, since they are used as development references. Inconsistencies among planning documents produced segmented urban environments in Kota Lama Semarang Area/Site, which are mostly due to the different institutions preparing the documents.

The segmented urban development in the area has reduced the historical and cultural values of the area. Revitalization program that was undertaken has some implication to the sustainability of the local economy.

The paper explores both the consistencies and mismatches among the three planning documents, which have been used as references in implementing development projects in Kota Lama Semarang Area. Failures in maintaining consistencies among documents are supposed to produce inconsistent physical development in the area, unless adjustment to current development has to be made.

Sweden, like other countries, has set ambitious national targets for both energy efficiency and conservation of heritage values in the built environment. However, how these policies are implemented on a local level and how they affect each other is not known. This study aims to argue that extensive energy-saving policies can have unintentional impacts not just on the built environment but also on conservation practice.

By using a longitudinal approach, the aim is to investigate the possibilities of conserving the built environment when policies for increased energy efficiency are implemented in existing urban areas. The methodology used is qualitative, applying a combination of study of public records, policy documents, interviews with public officials and ocular investigation of buildings in three areas located in two different municipalities.

The study suggests that extensive refurbishments not only have effects on the character of an area, but in extension, affect how urban planners and local authorities approach the development in the same area. Urban areas affected by extensive retrofits in the past seem to be managed in less detail, leaving existing policy measures on both energy and heritage untapped.

This is a study concerning two Swedish municipalities. Furthermore, it is limited to one specific policy measure, energy-saving subsidies provided in the 1970s and 1980s. The generalisability of the findings may, therefore, be limited. Despite this, the findings provide an important indication of the relationship between energy-saving policies in the past and urban planning practice of existing urban areas today, as well as the importance of alignment between policy-making and implementation.

Policy instruments for the building stock and the practice of conservation planning have not worked well together. Due to local practice, energy subsidies provided in the 1970s and 1980s still today have a negative effect on both heritage conservation and energy efficiency in existing areas.

There is a discrepancy between expectations and outcome of policy measures. National decision-makers overestimate the possibilities to control the development on a local level, for both energy efficiency and heritage values. By examining an innovative set of sources, acknowledging long-term effects and entanglements of policies and practice, this study contributes to a better understanding of the complexity of different values in the built environment.

By comparing the share of approved applications, as well as completed energy retrofits, this study demonstrates that the effects of the national energy subsidy policy differed significantly between urban areas. Areas with a high degree of approved subsidies also had a high degree of retrofits, suggesting that the policy had intended effects. In these areas, the number of retrofits were also significantly higher than the number of subsidies. This was not the case where energy subsidies were fewer, which indicates that energy retrofits are performative, meaning that they accelerate further retrofits in the same area.

The purpose of this paper is to investigate how different notions about the conservation of built heritage develop in a situation of structural change that demands either the demolition or relocation of a large number of historic buildings.

The analysis is based on a case study of the on-going urban transformation of the Swedish mining town Kiruna. The investigation was based on the text analysis of urban planning documents and media reporting, which was used to distinguish stakeholders’ positions towards conservation based on authenticity aspects.

The conservation goals of the urban planning process are unclear and the stakeholders have conceptually different views regarding which parts of the town’s built heritage are of significance, which negatively affects the ability to make well informed, transparent and intelligible management decisions. Stakeholder views on the management of built heritage span from the relocation of a few, single historic buildings to maintaining the integrity of the town as a heritage site by moving a significant number of buildings.

The Kiruna case, being exceptional because conservation in situ is impossible, has the potential to highlight the relation between single historic buildings and the integrity of an urban heritage site, as well as implications for conservation on the urban scale.

This investigation contributes to knowledge of built heritage in situations of structural change, which is of concern for planning and conservation practice. Currently, many urban areas are under pressure of transformations or destruction.

The purpose of this paper is to illustrate the relevance of cultural heritage inventories and documentation as critical tools for heritage conservation and management in historic cities, through the case study of the historic city of Ahmadabad, India.

The paper discusses the creation of inventories as part of the comprehensive documentation undertaken for preparation of the World Heritage nomination dossier. In this context, the goal of preserving the outstanding universal value of the historic city formed the basis for selection and assessment of the assets to be included in the inventory. Standard processes and methodology employed for creation of the database involved archival research and planning; field surveys for mapping, photo documentation and data collection; data registration and processing using CAD, Ms Office and geographic information system (GIS)-based digital platform. Optimal data acquisition while maintaining cost and time efficiency was an important consideration for the fieldwork.

While an inventory remains a critical conservation tool, the heritage assets are integrally linked to and influenced by their surroundings in an urban context. A comprehensive documentation approach that provides a broader understanding of the city’s natural features, built environment, heritage resources, cultural practices and socio-economic networks is therefore necessary for creation of a suitable management plan for historic cities. Traditional field surveys based on external visual observation are time and cost effective, and can generate adequate information on identification and assessment of built heritage assets for creation of inventory along with documentation of their context. However, the scale of investigation and the intended role of an inventory as an urban management tool calls for creation of integrated, accessible and updatable data management systems.

At the moment, the database created is only used for the limited purpose of monitoring and managing the conservation of listed properties. The importance of the inventory as a critical conservation and urban management tool can be further validated once the GIS database of the historic city is integrated within the urban management and planning system for the city.

The inventory created for the historic city of Ahmadabad offers one of the few examples of heritage documentation at such a large scale. It covers an area of 543 ha with a detailed inventory of more than 6,000 properties. The description of, and the reflections on the process employed provide an overview of usual challenges encountered in creation, presentation and management of heritage inventories for historic cities which may offer useful guidelines to practitioners planning similar exercises and help them establish efficient work processes.

The purpose of this paper is to identify the critical factors for enhancing social sustainability of the conservation of built heritage projects and to highlight the importance of addressing social sustainability in urban conservation.

First of all, a list of social sustainability factors is compiled from the international literature and then verified by a panel of experts in the field of heritage conservation and laymen through a pilot study in Hong Kong. Afterwards, through a questionnaire survey carried out in Hong Kong for an urban conservation project, the citizens' responses were obtained and evaluated. Results were derived from factor analysis.

The results indicated that social considerations should be incorporated for achieving social sustainability in urban heritage conservation. “Educational and local cultural promotion means”, “Meanings of the place”, “Social inclusion and psychological needs” and “Public participation and opportunity for skills development” were found to be the significant underlying factors for enhancing social sustainability of the case study project.

The underlying social factors found in this study can help enhance planning, management and implementation in conservation projects that should promote social well being in society.

The case study provides a valid basis for an interesting analysis on the relevance of the social sustainability aspects to an urban conservation project that also provides insights for other urban conservation projects of a similar nature. The factors identified can form an evaluation framework to measure the social sustainability level of a significant urban conservation and revitalization project in practice.

This article is an editorial to JCHMSD's Volume 3, Issue 1 and aims to provide an overview to its selection of papers.

The article builds upon a previous editorial on the implementation of the new UNESCO Recommendation on the Historic Urban Landscape (HUL). It discusses a research and training programme under development by the World Heritage Institute of Training and Research in Asia and the Pacific (WHITRAP) and Tongji University's Advanced Research Institute for Architecture and Urban Planning, in Shanghai, China, to help determining a strategy for the application of the HUL approach in China.

The HUL approach facilitates a structuring and priority setting of competing needs and demands for the integration of urban development and heritage management processes, which is perhaps most pressing in the current Chinese context of rapid and large‐scale urbanization. However, its precise meaning, and therefore its merit, is still poorly understood in China due to confusing conceptual foundations and interpretations, primarily related to the terminology of “cultural landscape”.

This research paper outlines a series of pertinent issues and questions as part of a critical path –a “road map”– for the application of the HUL approach, as promoted by UNESCO, in China and it outlines key areas for further research, in particular as concerns the development of a toolkit.

The article deals with the environmental consciousness emerged from the 1970's onwards, and with subsequent change in the ideology of city planning. The focus is on the development of urban conservation methods and on the maintenance of the built environment, which have marked a decisive shift away from the CIAM theses that dominated urban thinking during half-a-century. The decision to take the existing built environment as the starting point for all actions of city planning and design has been a radical stand for a new approach, corresponding to and paralleling the idea of sustainable development that crystallized in the 1980's up to the 1992 UN Conference. Grassroots-level strategies are considered important for all actions towards a sustainable way of life. The case of Finland is studied in some detail, with the conservation atlas of the historic milieu as an example of teaching a sustainable approach to environmental planning and design.

The paper aims to clarify threats facing heritage management in developing countries. It investigates the challenges facing the application of the historic urban landscape approach (HUL) in the city of Alexandria in Egypt, where heritage is trapped between unplanned developments from one side and deterioration from another side.

This paper uses SWOT analysis regarding the heritage management approach of the historic site. Site observation, documentary reviews, an online questionnaire (due to the COVID situation) and some interviews with park visitors and shopkeepers have been adopted to capture the changes in the site management, specifically capturing the current status of the site.

The paper presented an empirical study covering the evolution of heritage management practices. It suggests that building and maintaining the synergy between the government, the private sector and the public is essential for the sustainability of urban development in the city of Alexandria. It also asserts that heritage is a major catalyst of urban regeneration in the city.

This paper highlights major threats facing Alexandrian heritage. However, it lacks generalizability.

It suggests inclusive urban conservation strategies that are based on the HUL approach that would revitalize the historic core and assist in preserving both its tangible and intangible heritage. These strategies can help decision makers to develop more sustainable approaches in managing city heritage and achieving sustainable development of the city core.

The paper presents a social implication through involving stakeholders in the sustainable revitalization project of Al-Shalalat district located in the city center of Alexandria.

The paper presents an empirical study that fulfills an identified need for adopting more sustainable strategies in heritage management in Alexandria.

The purpose of this paper is to explore possible contributions of natural resources for the historic urban landscape (HUL) approach. It points to several possible avenues for collaborative research, which can expand the discourse on the topic of urban sustainability with different disciplines of heritage studies, natural resource management, urban planning and disaster risk reduction.

There are already several UNESCO initiatives such as the Man and Biosphere Programme, World Heritage Forests Programme and the World Heritage Programme for Small Island Developing States, which the HUL approach can learn from to understand approaches that integrate natural resource management in urban planning methods. Different cases from the USA, Japan and Singapore applying landscape approaches have also been documented in this research.

Several examples have been found in which natural resources are integrated to bigger strategies of urban planning. Japan has enacted the “Landscape Law” in 2004 to highlight the importance of preserving landscapes in improving the quality and viability of community life. The “Mauritius Strategy” created by small island developing states is another example. It holistically looks at policies to deal with environmental challenges while advocating economic growth and protecting cultural and natural heritage, among other concerns. The long tradition of creating greenways in the USA have also contributed in presenting heritage assets and providing environmental benefits. The High Line in New York City is a good example of this.

In line with the HUL approach, the research points out possibilities of non-traditional collaborations in solving current urban challenges. Finding ways of linking natural resources to a bigger urban framework can inspire new solutions for the interlinked problems of urban growth, heritage management and nature conservation amidst climate change.
