Losses from commercial activities reflect the decline and deterioration of the downtown, the urban fabric and the social structure of the cities. The dependence on motorized vehicles has grown significantly among consumers who must move to meet their daily needs. Such a process marginalizes vulnerable populations by promoting urban lifestyles less sustainable. Proximity trade is therefore becoming increasingly important for those groups because it encourages dynamism among distinct urban areas and reduces the use of vehicles. This urban model addresses a relevant issue as universal accessibility that allows residents to enjoy an available city and move freely without encountering obstacles. The major role played by trade in the creation of wealth and urban fabric demands the integration of commercial areas provisions into urban policy guidelines. In this context, the study aims at developing a set of indicators that link proximity trade with the promotion of sustainable urban development and the model of compact city to be included in Spanish urban planning guidelines. Sixteen indicators were thus formulated around five areas of action: urban morphology, urban complexity, sustainable mobility, urban metabolism and social cohesion.

Purpose The spatial development of urban areas affects the characteristics of landscape as well as people’s aesthetic perception of it. Specifically, sprawl results in an urban morphology which is diametrically opposed to the compact city model and which assumes several kinds of patterns: for example “striped”, “ribbon” or “leapfrogged” urban development. Assessing urban morphology in spatial terms is crucial to urban policy, while landscape metrics are the key to a comprehensive understanding of different urban development patterns. The purpose of this paper to design and test an urban morphology indicator (UMI) for the Lombardy Regional Landscape Plan. Design/methodology/approach The paper describes an UMI that can be used to identify the heterogeneity of built-up patterns according to urban porosity, fragmentation and patch shape. This UMI is a result of Esri ArcGIS 10.3 “grouping analysis” which works by applying a spatial statistical metric for clustering geometries in a given geographical area. Findings Morphological analysis was used in regional urban development policies with a view to minimising impact on surrounding ecosystems and preserving the natural environment and landscape. It defines 28 different urban morphology patterns in the region, which are divided into systems, polarities and urbanised units. Originality/value The proposed methodology differs from those traditionally used in qualitative/descriptive landscape planning and supports the identification of morphological features with quantitative statistical and spatial data, allowing a fine-scale assessment of complex metrics.

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.

<p>The European Union, its member states and local authorities have been working for long time on the design of solutions for future sustainable mobility. The promotion of a sustainable and affordable urban transport contemplates the bicycle as a mean of transport. The reasons for analysing the cycling mobility in urban areas, has its origin in the confrontation with motorized vehicles, as a sustainable response to the environment. In this context of sustainable mobility, the research team has studied the use of bicycles in Mediterranean cities, specifically in coastal tourist areas.  The present work shows the development of a mobility index oriented to the bicycle, transport that competes with the private vehicle. By means of a survey methodology, the research group proceeded to collect field data and the subsequent analysis of them, for the development of a mobility index adapted to bicycle mobility, and with possibilities to adapt to urban environments.</p>

The Impact

This study deals with the use of remote sensing (RS), geographic information systems (GISs), hydrologic modeling (water modeling system, WMS), and hydraulic modeling (Hydrologic Engineering Center River Analysis System, HEC-RAS) to evaluate the impact of flash flood hazards on the sustainable urban development of Tabuk City, Kingdom of Saudi Arabia (KSA). Determining the impact of flood hazards on the urban area and developing alternatives for protection and prevention measures were the main aims of this work. Tabuk City is exposed to frequent flash flooding due to its location along the outlets of five major wadis. These wadis frequently carry flash floods, seriously impacting the urban areas of the city. WMS and HEC-HMS models and RS data were used to determine the paths and morphological characteristics of the wadis, the hydrographic flow of different drainage basins, flow rates and volumes, and the expansion of agricultural and urban areas from 1998 to 2018. Finally, hydraulic modeling of the HEC-RAS program was applied to delineate the urban areas that could be inundated with floodwater. Ultimately, the most suitable remedial measures are proposed to protect the future sustainable urban development of Tabuk City from flood hazards. This approach is rarely used in the KSA. We propose a novel method that could help decision-makers and planners in determining inundated flood zones before planning future urban and agricultural development in the KSA.

The problem of inclusive development has recently taken into account in Ukraine, although at the global level and in the EU such discussions have been going on for a long time, as well as key concepts were included in the documents shaping the international policy agenda. The paper aims to identify local markers of inclusion and/or exclusion within the capital post-socialist city, verify participatory approaches within the context of sustainable urban development research, and create a basis for developing recommendations for further improvement of urban policy in Ukraine. The example of the capital, Kyiv, a city that has been integrated into the global economic landscape for several decades, is the most indicative from the point of view of current and anticipated changes. The article outlines the main features of modern discourse in the field of inclusiveness and integrated urban development. On the case of Kyiv and a few urban neighborhoods, based on a survey and expert assessment, local features of the spatial measurement of inclusiveness, such as accessibility and openness of different types of infrastructural objects, organization of urban space, have been analyzed. The surveys, in addition to positive assessments of the availability of urban infrastructure for residents, and high quality of construction of individual facilities, simultaneously have been revealed significant shortcomings, especially for people with disabilities. The role of urban governance and international projects outcomes to achieve new goals of urban environment quality in Ukraine has been emphasized. The scientific novelty of the article is to identify local signs of inclusiveness and exclusivity in the capital city of a post-socialist country in the context of improving urban policy in Ukraine.

Different Origins

Poucos conceitos têm sido tão amplamente utilizados como o de desenvolvimento sustentável, num aparente consenso revelador mais de imprecisão do que de clareza em torno de seu significado. Com base em uma revisão de abordagens recentes, argumenta-se que a noção de desenvolvimento urbano sustentável traz consigo conflitos teóricos de difícil, porém não impossível, reconciliação: a) entre as trajetórias da análise ambiental e da análise urbana que, originando-se em áreas do conhecimento diferentes, confluíram na proposta de desenvolvimento sustentável; b) entre formulações teóricas e propostas de intervenção, traduzindo-se no distanciamento entre análise social/urbana crítica e planejamento urbano. São examinadas propostas de planejamento que adotam o discurso e/ou pressupostos de sustentabilidade urbana, discutindo exemplos da literatura internacional — as cidades compactas européias, o movimento californiano por cidades sustentáveis — e, no caso brasileiro, a experiência recente de planejamento urbano em Belo Horizonte.Palavras-chave: planejamento urbano; desenvolvimento sustentável; meio ambiente; política urbana. Abstract: Few concepts have been so widely adopted as sustainable urban development, an apparent consensus revealing more imprecision than coherence of meaning. The paper discusses some aspects of such theoretical and conceptual fragility as a contribution to building an alternative for the future. The concept is considered to have been worn out by excessive fashionable repetition. The paper argues, however, based on a review of recent approaches ranging from political economy to the contributions of political ecology and post-structuralism, that the concept of sustainable urban development embodies conflicts that are difficult but not impossible to solve: a) the conflict between the different origins of and paths followed by environmental analysis and urban analysis, both converging on the proposition of sustainable development; b) the conflict between theory and practice represented by the growing distance between critical social/urban analysis and urban planning. Finally, some planning proposals are examined as examples of adoption of the discourse and assumptions of sustainable development. They are the European compact city proposal; the Californian sustainable cities movement; and, in the Brazilian case, the recent urban planning experience in Belo Horizonte.Keywords: urban planning; sustainable development; environment; urban policy.

The reuse of industrial zones is becoming one of the determinants of sustainable urban development, which ensures the effective use of urban areas, taking into account the principle of their integrated development. However, the modern urbanized environment has serious environmental problems, which limits the active use of the redevelopment tool. The conducted research of the implemented redevelopment projects showed that their main share is accounted for the construction of apartments and housing, multinational complexes, creative spaces and offices. The results of the cluster analysis of the territories of Russia allowed the authors to identify the most promising regions for redevelopment.

This paper examines empirically and spatially how welfare gains are realized in a land pooling scheme in four ADB-financed Local Area Plans (LAPs) in Thimphu city, Bhutan. Increased government efforts are required to take advantage of the full range of benefits of land pooling for Thimpu residents. The paper recommends a mix of fiscal and urban policy levers to address inefficiencies associated with the existing build-out pattern and infrastructure service quality. It offers insights on how unplanned development occurring outside serviced LAP areas, including along steep slopes and peri-urban areas in Thimphu thromdes, can be addressed most effectively. This paper is the second in a series of three working papers on the topic of land pooling produced by the Asian Development Bank’s South Asia Urban Development and Water Division. The series takes a deeper look at aspects including land pooling’s effectiveness, welfare-improving potential, relationship with safeguard policies, and its prospects as a land management tool in developing country cities.
