This paper proposes the integration of GIS (Geographic Information System ) and HMA (Hierarchical Multi-criterion Analysis) offering a low-cost methodology to produce vulnerability maps. The quintessential role the rivers play in urban development has long been asserted and accepted. However, one of the subsequent consequences of these urban development activities is the increased frequency of floods. The case in point is the city of M’sila, Algeria. The subject city was settled along the banks of a river known as Oued El Ksob, which undoubtedly had a significant influence on its development. In the last 50 years, M’sila has experienced significant spatial growth, especially in its north and northwest sides. As such, the work presented in this article aims to assess the vulnerability of the city to the risks of flooding. The approach used is based on the combined use of the HMA method coupled with the GIS. The process allowed the graphical representation of the resulting analysis of complex data of the territory, i.e. the mapping of its vulnerability to flooding. The map has four vulnerability categories ranging from low to very strong. The proposed system serves as an essential decision-making tool for local government officials.

Contraction, downsizing, rescaling and subtraction are all words that characterise the urban planning debate with increasing frequency. Two components can be found at the basis of their circulation and declination.On the one hand, the recognition of the vast unused and disused real estate for which regeneration, reuse and renovation are not possible; on the other hand, the will and hope to rebalance the results of the hypertrophic twentieth-century urban development. The legitimacy of these instances is the wides pread belief that demolition and contraction are low-cost operations that can be financed by the owners of the property or through the usual equalisation and negotiation mechanisms. By using a case study, this paper will clear up amis understanding; it will explain how demolition and subtraction costs, which can be put on equal footing with renovations and, in some cases, new construction are sufficiently massive making their implementation within the public and public-private policies very difficult.

This paper explores what it means for a public space to embody the city within rapid urban change in contemporary urban development and how a space can accomplish this by embracing the culture of the city, its people and its places, using the particular case of Putuo, Shanghai in China. The paper employs mapping and empirical surveys to learn how the local community use the act of communal dance in everyday public spaces of this neighborhood, and seeks not to find generalizable rules for how humans comprehend a city, but instead to better understand how local inhabitants and their chosen activities can influence their built environment. The findings from this emphasize the importance to identify how public spaces can help to define cities with China’s emerging global presence, whilst addressing the ways in which local needs and perspectives can be preserved.

Information about the land use of built-up areas is required for the comprehensive planning and management of cities. However, due to the high cost of the land use surveys, land use data is out-dated or not available for many cities. Therefore, we propose the reuse of up-to-date and low-cost place data from social media applications for land use mapping purposes. As main case study, we used Foursquare place data for estimating nonresidential building block use in the city of Amsterdam. Based on the Foursquare place categories, we estimated the use of 9827 building blocks, and we compared the classification results with a reference building block use dataset. Our evaluation metric is the kappa coefficient, which determines if the classification results are significantly better than a random guess result. Using the optimal set of parameter values, we achieved the highest kappa coefficient values for the land use categories “ hotels, restaurants and cafes” (0.76) and “ retail” (0.65). The lowest kappa coefficients were found for the land use categories “ industries” and “ storage and unclear”. We have also applied the methodology in another case study area, the city of Varese in Italy, where we had similar accuracy results. We therefore conclude that Foursquare place data can be trusted only for the estimation of particular land use categories.

Comprehensive urban development varies from place to place according to the different natural environment, unplanned urban development on coastal cities led to an urban disruption and random possession of lands, Burj Al-Burullus is a coastal city with high environmental sensitivity and has many environmental, social, and cultural systems that qualify it to be a development area with a distinct character. The challenges of urban development represent the biggest challenge to development in the region. Despite the presence of many development plans in the region, there is no clear methodology that considers the resources and the distinct potentials of these areas to make use of them in solving the problems that hinder development. The research presents an attempt to reach a mechanism through which sustainable urban development can be achieved in all economic, social, and demographic aspects. In addition, it contributes to formulating a vision and developing a strategy to achieve sustainable urban development, with the participation of economic institutions in a way that stimulates these institutions to invest. The research studies and evaluates the current reality of Burj Al-Burullus city using GIS in terms of the characteristics and activities of the city and explores its developmental reality. The research attempts to find appropriate urban solutions to overcome these urban challenges and develop plans to be used as a link between the challenges and development results and to be followed in the development of the region and similar areas.

Brownfields are "abandoned, vacant, derelict or underutilized commercial and industrial properties where past actions have resulted in actual or perceived contamination" (NRTEE, 2003, p.1). Brownfield redevelopment, because of its contributions to urban sustainability, intensification and environmental quality, has become a critical issue in urban development literature of late. Through case-study research this paper aims to evaluate the relative sustainability of four Port Lands brownfield redevelopments that involve converting brownfields into green space in the City of Toronto. This study has shown how brownfield redevelopment and more specifically, turning brownfields into green space represent an application of all three pillars of sustainability. However, the exact extent of how this type of redevelopment represents an application of sustainable development cannot be truly measured or quantified. It has also highlighted the need to develop a comprehensive set of sustainability indicators that can be specifically applied to projects that aim to convert brownfields into green space.

Urban vitality is the primary driver of urban development. However, assessing urban vitality has always been a challenge. This paper builds on the research framework of sustainable development evaluation and selects evaluation indicators from the three systems of urban operation: economy, society, and environment. The deviation maximization (DM) method is used to evaluate urban vitality. Shanghai is then used as a case study for evaluation, and the comprehensive index of urban vitality is calculated for the city from 2010 to 2019. The evaluation results indicate that the urban vitality of Shanghai experienced a significant upward trend over ten years (2010–2019), which shows that the urban competitiveness of Shanghai is constantly strengthening. Next, the study focuses on the administrative region of Shanghai, to calculate the regional vitality level of Shanghai from 2010 to 2019 and to explore its spatial distribution characteristics. Then, a spatial autocorrelation analysis is used to explore the mechanism that affects the spatial distribution of urban vitality. The results demonstrate that the urban vitality in Shanghai shows a significant positive correlation in space. Moreover, there is a “High–High” gathering area, which includes Huangpu, Xuhui, Hongkou, and Changning in central area of Shanghai. This research provides a theoretical reference to support effective decision-making with respect to high-quality urban development.

Smart cities are an extremely important, multi-faceted subject, both in terms of their practical aspects and in terms of research. This is expressed, among other things, in the multitude of approaches to this concept. These approaches differ based on the emphasis placed on individual aspects: some focus more on technology, and others put more weight on social issues, while still others value sustainable development issues. Currently, an important topic of discussion about the development of the smart city—the importance of which has become even greater in the context of the COVID-19 pandemic—is the digital transformation of the city. The use of robotic process automation (RPA) tools can be a part of such a transformation, as such tools, using advanced software, enable the automation of those tasks carried out thus far by humans. Although such an approach has, to date, been widespread in the case of enterprises (in particular, those operating in the financial and BPO/SSC sectors, but less often in the utilities sector, the first applications of these solutions in the context of process automation for cities are also beginning to emerge in various parts of the world. This article is based on a case study approach. The implementation conditions (including the constraints) of such an approach, the benefits achieved, and the lessons learned (which can be important for other local government units) are outlined using the example of the Bydgoszcz city hall’s (Poland) electricity billing document management. The results of the case study presented here lead to the conclusion that the use of RPA tools enables, very quickly and at relatively low cost, measurable results to be achieved that are related to the processing of electricity billing documentation for the city of Bydgoszcz. This allows the assertion to be made that robotic process automation can be taken into consideration as one of the tools used to build smart cities.

Some cities in Indonesia have a long history of city development, in East Java, for example the cities of Surabaya, Malang, Blitar, Kediri and Pasuruan are cities that have a history of urban development that still maintains the identity of the city. old buildings or colonial buildings, these buildings can still be suspected through the characteristics of building shapes and the use of ornaments that are characterized by European buildings. For this European building to be preserved, it is necessary to conduct a feasibility study of the aesthetic value contained in the building. The case study taken in writing this article is the Pancasila Building in the city of Pasuruan. The method used is descriptive analysis topically. To support the discussion in this article, field observations and literature studies were conducted. The findings in this study were to determine the physical identity of the building and the meaning of building ornaments.

Bridgeheader is one of the typology of low-income people in the city who assume that the house is only ‘a springboard’ for their life in the city. This group of people dwelt not far from the location of their place to work; occupying marginal spaces in the city and its environment tend to be slump. Almost all areas in the city of Jakarta have marginal spaces, therefore the government attempt to improve the quality of their houses, for example by providing low-cost housing. In fact the low-cost house which was provided by the government failed to be ‘consumed’ by the brigdeheaders at the time when the used value of the house has been turned into market value. The research aimed to determine such approaches of use value of the house that can be ‘consumed’ by the brigdeheader, but did not undermine the space in the city. Data collection methods using practical observation conducted with interviews. While the analysis using descriptive pragmatic method in four case study area in Jakarta. The findings indicate that the concept of house for this group is not determined only by the ‘low price tag’ but also ‘the way of use’ of the space contributed with the result that the house can be ‘consumed’ well.
