Integrating and advancing social sustainability is foundational to achieving the urban sustainable development goals. Given the rapid transformation of cities in the Mediterranean region, this study sought to assess residents' evaluation of social sustainability in two socio-spatially diverse neighbourhoods of metropolitan Istanbul.

A questionnaire survey, adapted from an empirically well-tested and robust social sustainability framework, was used to collect data from 197 residents from Balat and Rasimpasa neighbourhoods in Metropolitan Istanbul. The study then employed quantitative analytical techniques such as independent sample t-tests and Pearson correlation to analyse the sample data.

In both neighbourhoods, accessibility and participation were ranked the highest and lowest dimensions of social sustainability, respectively. However, the t-test analysis revealed a statistically significant difference between the two neighbourhoods regarding social networking and interaction, safety and security and participation. The differences align with emerging studies on urban social sustainability in the Mediterranean and European cities that when considered from urban spatial contexts, significant differences emerge from a social network and safety perspective.

Our study invites urban planners and policy makers attention to and emphasise on lowly evaluated social sustainability dimensions such as participation in their efforts to promote sustainable urban development at the neighbourhood level. We reason that opening the decision-making process to include diverse voices and experiences of residents through participatory workshops might offer opportunities for context-specific, citizen-led urban planning and design strategies that are socially sustainable.

Previous studies have not fully accounted for how various socio-spatial contexts at the neighbourhood level shape differential evaluation of social sustainability. This paper extends the emerging work on urban social sustainability by situating residents’ evaluation of social sustainability indicators across two unique neighbourhoods with gridded and organic spatial characteristics in Istanbul. This paper is an important addition to ongoing work on how spatial organisation of neighbourhoods can influence experiences of social sustainability from an urban planning and design perspective.

In an urbanising world, neighbouring is perceived to be steadily losing significance and a remnant of the past. The same belief can also be found in China where rapid urbanisation has had a tremendous impact on the social networks and neighbourhood life of urban residents. This chapter challenges the common perception of neighbouring in demise and argues that neighbouring remains an important form of social relationship, even if the meanings and role of neighbouring have changed. This chapter first charts the changing role of neighbouring from the socialist era to post-reform China. It then provides an account of four common types of neighbourhoods in Chinese cities – work-unit estates, traditional courtyards, commodity housing estates and urban villages – and considers how and why neighbouring in different ways still matters to them. In pre-reform socialist China, neighbourhood life and neighbouring comprised much of the daily social life of residents. Since the reform era, with the proliferation of private commodity housing estates, middle-class residents prioritise comfort, security and privacy, such that neighbouring levels have subsided. Nevertheless, in other neighbourhood types, such as work-unit housing estates, traditional courtyards and urban villages, neighbours still rely upon one another for various reasons.

The research intends to investigate the different typological and morphological characteristics of the neighbourhood spaces produced by different urban dynamics since the late nineteenth century in Turkey.

The main problem that drives the research is that a significant increase in the construction of gated communities has started to be seen in the last five years as a solution to safety issues in Turkey. However, these gated communities as safe-spaces have resulted in the danger of destroying neighbourhood life's physical and social dynamics by changing their spatial configuration. The study offers an analytical framework structured from defensible space theory and other safe-space theories in the literature. It has analysed the effect of physical characteristics of urban fabric on the production of safe-space in neighbourhoods through mappings and site observations. The case studies are conducted in three different morphological periods in Turkey, which are the Seyrancik neighbourhood in Bolu (the Ottoman Period), the Subayevleri neighbourhood in Ankara (the Republican Period) and the Karaman neighbourhood in Sakarya (the Liberalisation Period).

The analysis concludes that any type does not come to the fore in the production of defensible space in terms of its spatial features, but each has various strengths and weaknesses. As a result, this study emphasises the role of design in providing defensible neighbourhoods in the case of Turkey's cities and reveals the aspects that will guide the design of an urban and housing form in terms of the safety–environment relationship in Turkey.

The significance of the study is the comparative analytical approach to studying the housing development and demonstrates a method for analysing safety issues in the transformation process of neighbourhood structures in Turkey.

The purpose of this paper is to review, analyze and synthesize different pieces from literature to explore, define and describe the concept of social capital and its relationships with urban neighborhood design concepts. Additionally, to define the indicators and principles that can enhance social capital within urban design context. Moreover, to suggest theoretical urban neighborhood design concept that can adopt the changing discourse of social capital.

This research used the theoretical, analytical and descriptive approach-driven case study method. In all, 29 papers were analyzed to conclude the indicators that can measure social capital within the urban neighborhood design context and to conclude the required neighborhood design features and principles that influence social capital. Additionally, two new urban neighborhoods design concepts, cohousing and hybrid concepts that adopt new forms of social interaction, were studied, analyzed and then synthesized to suggest new neighborhood design concept, which is a heterotopia concept.

Heterotopia neighborhood concept aims to create real, different and heterogeneous functional spaces with different layers of meanings for people from different cultures in one place. Different visible enclosures are merged into spaces of otherness while the diversity gives a sense of entering another alternative place. The heterotopias neighborhood design principles aim to create a wide variety of forms, shapes and elements [different new spaces for different ritual activities to reflect the otherness self-reflection (homogeneous and scattered spaces)] and create linkage, hierarchy, contrast and mingling between spaces and places; well-defined functional effective spaces; different fantasy and leisure spaces; high standard quality of life and otherness space; flux in social realm and fluidity of spaces; mixed use and joint experience; and innovated technologies spaces to offer strange new temporalities.

This research recommended that different community stakeholders should participate in planning process, neighborhood urban design and decision-making process about public spaces to strengthen the community ties and achieve a heterotopia concept. Architect, urban designers and planners should adopt bottom-up design approach when designing neighborhood. Additionally, to avoid poor social capital research studies, the new researchers, practitioners and journal reviewers approaching social capital for the first time must read widely to gain an understanding of the concept from different perspectives and narrow their scope to their particular area of interest.

This research highlights the needs for empirical studies to examine the relationships/interrelationships between all neighborhood design principles and social capital. This might increase the knowledge on how we can design and increase the quality of neighborhood to foster social capital, which might offer interesting insights into how neighborhood urban design principles are combined to foster social capital within neighborhood context.

Neighborhood-based research encourages new suggesting concepts in designing every single place in the residential neighborhood in a way that can adapt the new forms of social interaction. This research scanned the current concepts of neighborhood design that concerned successfully with the changing forms of social relationships to conclude some design features and principles for neighborhood design to ensure and promote social public health and well-being. This research offers a unique perspective for better understanding the relationships between the neighborhood urban design as a spatial dimension and social capital. This research aims to enrich the socio-spatial knowledge and build a resilient urban community by suggesting theoretical urban neighborhood design concept, which is the heterotopia concept, and providing the urban designers and architects with a valuable thinking tool to design spaces.

While the declining rate of urban security and its potential effects have been globally acknowledged, the ways urban neighborhood security shapes real estate markets in African cities remain largely unexplained. The purpose of this paper therefore is to present the findings from a study of the nexus between urban neighborhood security and home rental prices in Lagos, Nigeria.

This paper is based on the hedonic price theory, an objectively derived urban neighborhood security index (UNSI) and property rental price data in Ojo, Lagos, Nigeria. This is a quantitative cross-sectional study that employs multistage sampling survey procedure. Data are analyzed using descriptive statistics, nonparametric correlation and hedonic price function with ordinary least squares (OLS).

Results show that nearly 50% of the study area is prone to insecurity and average rental values in Ojo, Lagos range from N151329.41 ($302.66) to N167333.33 ($334.67) per annum. Correlation analysis shows that home rental prices have high, positive and significant correlations (rs = 0.725 and p < 0) with UNSI. After controlling for neighborhood and structural factors, it is found that urban neighborhood security positively influences home rental values as a unit improvement in security leads to N81000.00 ($162.00) increase in rental value per annum.

Urban neighborhood security risk threatens residential property values, creates unintended residential mobility and destabilizes families. Findings from this study point to the facts that security is a key component of urban housing values and developers, and real estate investors must ensure that this component is well factored into property design, construction and valuation.

This is perhaps the first study that uses an objectively derived UNSI to study home rental price dynamics in Nigeria. The study extends knowledge on urban housing price determinants and contributes to literature on the crucial place of security in property management.

This research aims to develop a method for defining the identity of multilayered neighbourhoods by taking a case study in Nantes/France. It utilizes the urban identity concept to achieve this goal, which is defined by physical and identificatory relation to the neighbourhood.

The methodology includes historical periodical analysis, housing form and architectural stylistic definition, visualization and geographic information system (GIS) mapping. The research conducts spatial analysis to reveal the physical component of the urban identity of the neighbourhood and interviews (No = 50) with dwellers for the identificatory relation, asking about neighbourhood tangible/non-tangible elements. All these data are mapped through GIS.

The study found that the physical component is defined by three urban layers (identified as industrial, reconstruction and development, and post-industrial) and eleven housing typologies. As for the identificatory relation, the authors found that the interviewees mostly identified with their neighbourhood, whereas a minority did not. The most important form of identification with the neighbourhood was its atmosphere, and as reasons were given, the neighbourhood's positively evaluated quality, good location and social values.

It proposes the definition of the physical component through urban layers and housing typologies. The identificatory relation also considers the identification of the residents with the neighbourhood's tangible/non-tangible urban elements.

The neighborhoods north and northwest of downtown St Louis are blighted by their abundance of substandard, abandoned, and demolished housing. Crime, poverty, and unemployment are high while family stability, educational achievement, and health outcomes are low. These conditions are not unique to St Louis, but can be found in neighborhoods in every city in America. How did this happen? What factors led to the demise of these neighborhoods? This chapter examines the history of St Louis along with theories of neighborhood succession to identify possible explanations for the city's collapse.

The urban population in Indian cities is increasing at an alarming speed. Accommodating such a huge population while sustaining the environment is a challenge in urban areas. Compact urban forms with high-density planning is claimed to be a sustainable solution in such situations. Thus, this approach needs to be tested for Indian urban areas.

This paper formulates a neighbourhood sustainability assessment (NSA) framework for monitoring, assessing and managing the population density of urban neighbourhoods. The paper identifies context-specific built density indicators at the neighbourhood scale. It assesses the indicators in neighbourhoods with varying population density by physical and perceived measures. This helps in verifying the feasibility of density by physical density assessment and verifies the acceptability of density by perceived density assessment.

When tested in the Indian context, the framework shows that although high-density neighbourhoods are sustainable, certain indicators may endorse differing densities. The result displays that high-density planning is sustainable compared to low- and medium-density neighbourhoods in the selected cities.

The study demonstrates the application of formulated assessment system in three central Indian cities with useful results. Similar studies can be conducted to identify the gaps for improving sustainability and achieve a livable density pattern.

Although sustainable development goals are part of new planning policies, there exist very few assessment systems to determine the sustainability of neighbourhoods, especially for density. The methodology will assist in developing sustainability assessment frameworks and encourage the practice of sustainability assessment in developing countries like India.

This study aims to identify the challenges of new urban housing zones in Algeria that have permitted the emergence of many habitat neighbourhoods deprived of all services. The objective is to promote social interaction by departing from the zoning and introducing the notion of urban mix.

This study tries to catch different elements that contribute to promote the degree of social interaction. This step ultimately has led to the need to improve the quality conditions of the living environment and focus the analysis on urban mix advantages. The latter aims to organize space by balancing functional, social and spatial magnitudes. Different methods have been adopted to assess each dimension. Starting with the assessment of the functional mix, the functional mix coefficient (C.Mix f) was calculated in a quantitative approach, and attendance rates of various targeted functions were determined in a second qualitative one. However, regarding the social mix, several evaluation criteria were selected. Finally, the spatial mix was evaluated via three modes of occupation; mix on the islet, mix on the parcel and mix on the building.

The results of this research confirm that urban mix is imperative to counteract problems generated by zoning. It also concludes that urban mix can be assessed through a grid of indicators. The case study of Ayouf-Jijel revealed that it benefits from good coverage of amenities and businesses; the authors also found that most indicators present some qualitative rather than quantitative deficiencies. This concerns the location of businesses in collective and individual housing. This phenomenon is scattered in the neighbourhood’s development.

The objective of this paper is to contribute to the argument on how to develop neighbourhoods in a city in general and particular to the city of Jijel through the urban mix by taking into account several indicators under three measurements: functional, social and spatial. In addition, the paper contributes to discuss new methods for the evaluation and implementation of urban mix. Finally, this paper reveals an opportunity to rethink neighbourhoods regarding new approaches and reflections of cosmopolite development versus zoning.

The purpose of this paper is to present a methodology to quantify the solar energy potential for applying photovoltaic systems and find an efficient geometry for urban blocks to obtain a better quality of daylighting in terms of continuous daylight autonomy (DA) and spatial DA with less energy consumption.

The paper is based on a complete simulation of the topography and micro-climate of the area under study. Simulations were performed using ArcGIS and Rhinoceros and urban daylight (UD) and urban modeling interface plugin for a neighborhood in the region of Narmak in Tehran, Iran. Five configurations of a neighborhood were compared using simulations.

It was found that the impact of the geometrical form on daylight gain and energy consumption is significant and the terraced model is the most suitable form for obtaining a constant floor area ratio. Furthermore, it is an optimal form of urban blocks to gain the most energy through photovoltaic systems in the neighborhood as it would be able to satisfy about 42 percent of the energy needs.

Planning to achieve sufficient energy factors in cities is a difficult task, since urban planners often do not have adequate technical knowledge to measure the contribution of solar energy in urban plans and this paper aims to introduce a comprehensive modeling methodology by which the urban energy planning can be used and understood in the urban context to make it completely clear as a strategy of implementation.
