The concept of participation in sustainable urban development practices is actually more and more popular in Europe and all over the world. In parallel, there is a rapid growth of urban design and planning projects including local communities in urban development planning activities. According to such concepts, this chapter, starting from the description of the results of field and desk researches carried out by ‘La Sapienza' University of Rome and related to communities involvement strategies currently available in Europe, describes and analyses a case study based on a concrete application of theoretical and methodological approaches, and two more cases of possible application of an integrated methodology.

Quantitative and accurate urban land information on regional and global scales is urgently required for studying socioeconomic and eco-environmental problems. The spatial distribution of urban land is a significant part of urban development planning, which is vital for optimizing land use patterns and promoting sustainable urban development. Composite nighttime light (NTL) data from the Defense Meteorological Program Operational Line-Scan System (DMSP-OLS) have been proven to be effective for extracting urban land. However, the saturation and blooming within the DMSP-OLS NTL hinder its capacity to provide accurate urban information. This paper proposes an optimized approach that combines NTL with multiple index data to overcome the limitations of extracting urban land based only on NTL data. We combined three sources of data, the DMSP-OLS, the normalized difference vegetation index (NDVI), and the normalized difference water index (NDWI), to establish a novel approach called the vegetation–water-adjusted NTL urban index (VWANUI), which is used to rapidly extract urban land areas on regional and global scales. The results show that the proposed approach reduces the saturation of DMSP-OLS and essentially eliminates blooming effects. Next, we developed regression models based on the normalized DMSP-OLS, the human settlement index (HSI), the vegetation-adjusted NTL urban index (VANUI), and the VWANUI to analyze and estimate urban land areas. The results show that the VWANUI regression model provides the highest performance of all the models tested. To summarize, the VWANUI reduces saturation and blooming, and improves the accuracy with which urban areas are extracted, thereby providing valuable support and decision-making references for designing sustainable urban development.

Purpose The purpose of this paper is to examine social sustainability effectiveness of eco-cities through the case of Masdar City’s strategy for urban sustainability in Abu Dhabi, United Arab Emirates. Design/methodology/approach Using a case study approach, the paper is an exploratory, qualitative analysis, which investigates the social, environmental and economic performance of Masdar City, a purported carbon-neutral, zero-waste urban development. Findings Though Masdar City substantively contributes to innovation in sustainable urban development within environmental and economic contexts and has been effective in capital circulation in green technology markets, the impetus as a commercially driven enterprise is most evident. Successful sustainable urban development requires greater consideration for the social imperative. Practical implications Eco-city mega-projects, such as Masdar City, have the potential to fuse achievements in innovation, technology and economic enterprise with the social imperative of functional urban habitats. Originality/value Eco-cities are of increasing interest given the growing need for sustainable, energy-efficient living. This paper contributes through a novel case study, exploring how the concept of the eco-city has been developed and understood in the Masdar City context and discusses successes and deficits in its strategic implementation.

This paper addresses the need to develop a Local Geospatial Data Infrastructure (LGDI) for sustainable urban development. This research will highlight the effective and efficient framework for the development of local infrastructure. This paper presents a framework (a combination of domain based and goal based frameworks) for developing a Local Geospatial Data Infrastructure. The basis of this research is on a case study conducted in a Malaysian city. The main focus of the case study was on measuring and assessing sustainability. Six conceptual frameworks were produced based on 6 key dimensions of sustainability. The developed framework consists of 6 conceptual data models and 6 conceptual data structures. It was concluded that 30 spatial data layers are needed of which 12 data layers are categorized as point shape, 17 data layers are categorized as polygon shape and 1 data layer as line shape category.

Two Phases

The need for a mid-tier transit system and the opportunities created by 21st century transit technologies like Trackless Trams System (TTS) has been analysed in an earlier paper to show TTS could be a leapfrog solution for the future of sustainable urban development in developing cities. This paper outlines how the TTS can be created as a part of Transit Oriented Development (TOD). Informed by literature, this study identified four factors that are important for enabling transition towards TOD. Using three of these factors a framework for assessing and evaluating TOD is formulated. The study then applies the formulated framework to the potential corridors that could potentially enable a transition towards a successful TOD for Bulawayo and enable the TTS to be delivered in a partnership with urban land development. The findings do reveal that most of the station precincts that are closer to the CBD have a higher potential to enable transition to TOD. This could suggest that the TTS could be implemented in two phases, the first phase covering the high impact station precincts.

This paper focuses on the suitability of urban expansion in mountain areas against the background of accelerated urban development. Urbanization is accompanied by conflict and intense transformations of various landscapes, and is accompanied by social, economic, and ecological impacts. Evaluating the suitability of urban expansion (UE) and determining an appropriate scale is vital to solving urban environmental issues and realizing sustainable urban development. In mountain areas, the natural and social environments are different from those in the plains; the former is characterized by fragile ecology and proneness to geological disasters. Therefore, when evaluating the expansion of a mountain city, more factors need to be considered. Moreover, we need to follow the principle of harmony between nature and society according to the characteristics of mountain cities. Thus, when we evaluate the expansion of a mountain city, the key procedure is to establish a scientific evaluation system and explore the relationship between each evaluation factor and the urban expansion process. Taking Leshan (LS), China—a typical mountain city in the upper Yangtze River which has undergone rapid growth—as a case study, the logic minimum cumulative resistance (LMCR) model was applied to evaluate the suitability of UE and to simulate its direction and scale. The results revealed that: An evaluation system of resistance factors (ESRFs) was established according to the principle of natural and social harmony; the logic resistance surface (LRS) scientifically integrated multiple resistance factors based on the ESRF and a logic regression analysis. LRS objectively and effectively reflected the contribution and impact of each resistance factor to urban expansion. We found that landscape, geological hazards and GDP have had a great impact on urban expansion in LS. The expansion space of the mountain city is limited; the area of suitable expansion is only 23.5%, while the area which is unsuitable for expansion is 39.3%. In addition, it was found that setting up ecological barriers is an effective way to control unreasonable urban expansion in mountain cities. There is an obvious scale (grid size) effect in the evaluation of urban expansion in mountain cities; an evaluation of the suitable scale yielded the result of 90 m × 90 m. On this scale, taking the central district as the center, the urban expansion process will extend to the neighboring towns of Mianzhu, Suji, Juzi and Mouzi. Urban expansion should be controlled in terms of scale, especially in mountain cities. The most suitable urban size of LS is 132 km2.This would allow for high connectivity of urban-rural areas with the occupation of relatively few green spaces.
