Current urban and transport planning practices have significant negative health, environmental, social and economic impacts in most cities. New urban development models and policies are needed to reduce these negative impacts. The Superblock model is one such innovative urban model that can significantly reduce these negative impacts through reshaping public spaces into more diverse uses such as increase in green space, infrastructure supporting social contacts and physical activity, and through prioritization of active mobility and public transport, thereby reducing air pollution, noise and urban heat island effects. This paper reviews key aspects of the Superblock model, its implementation and initial evaluations in Barcelona and the potential international uptake of the model in Europe and globally, focusing on environmental, climate, lifestyle, liveability and health aspects. We used a narrative meta-review approach and PubMed and Google scholar databases were searched using specific terms. The implementation of the Super block model in Barcelona is slow, but with initial improvement in, for example, environmental, lifestyle, liveability and health indicators, although not so consistently. When applied on a large scale, the implementation of the Superblock model is not only likely to result in better environmental conditions, health and wellbeing, but can also contribute to the fight against the climate crisis. There is a need for further expansion of the program and further evaluation of its impacts and answers to related concerns, such as environmental equity and gentrification, traffic and related environmental exposure displacement. The implementation of the Superblock model gained a growing international reputation and variations of it are being planned or implemented in cities worldwide. Initial modelling exercises showed that it could be implemented in large parts of many cities. The Superblock model is an innovative urban model that addresses environmental, climate, liveability and health concerns in cities. Adapted versions of the Barcelona Superblock model are being implemented in cities around Europe and further implementation, monitoring and evaluation are encouraged. The Superblock model can be considered an important public health intervention that will reduce mortality and morbidity and generate cost savings for health and other sectors.

This article presents central settlements in Slovenia and their main characteristics in 2016. We defined central settlements based on services of general interest and the population of an individual settlement, and developed the analysis further by using competitiveness indicators. We defined 360 central settlements at six levels of centrality, among which the significance of Ljubljana as a national center of international importance and the significance of intermunicipal, local, and rural centers are increasing. The significance of certain regional centers at the second and third levels of centrality is decreasing. The level of services of general interest supplied to Slovenian territory is relatively appropriate, but it should be improved by promoting competitiveness, especially in centers of national and regional importance.

Quality of urban life is a useful concept for studying the quality of residential environment and its effect on quality of life. The article is based on the data analysis of the survey research Quality of Life in Ljubljana (2010). Using structural equation modelling and hierarchical multiple linear regression analysis, the effect of residential quality on quality of life was determined and compared to the effects of selected domains of life. The results depend heavily on the operationalization of quality of life and on the selected independent variables in the model. Structural equation modelling confirmed the hypothesis about the effect of residential quality on quality of life, wherein satisfaction with the dwelling has a significantly greater effect on it than satisfaction with the neighbourhood and with living in the city. The hierarchical regression analysis results show that the quality of life for Ljubljana residents is most affected by their own estimation of social-economic factors, especially economic well-being, family life, and social life.

The socioeconomic performance of industrial small and medium-sized towns (SMSTs) in comparison to that of non-industrial SMSTs, is subject to evaluation in this paper, to see if the presence of industry has adverse effects on socioeconomic factors. We studied 32 variables accounting for dimensions of socioeconomic performance in Slovenian SMSTs and conducted various statistical tests. We found only minor differences between the two groups, pertaining mainly to some elements of economic structure and demography, and some mixed relations of industrial employment and socioeconomic performance. The results demonstrate that industrial SMSTs should not be labelled automatically as ‘disadvantaged’. We discuss why our results differ from general research expectations in the literature: in the local context, we outline the “egalitarian syndrome” and policies of polycentric spatial development; in the global context, we discuss the “failed tertiarisation effect” and the differences between post-socialist and “Western” countries. We conclude by proposing that research should be re-oriented towards the more place-sensitive issues of industrial towns across Europe.

Cultivated terraces distinctively mark the landscape and are a result of human adaptation to steep areas. Terraces were studied with regard to their morphometric qualities, ownership structure, and land use at eight pilot sites in various landscape types in Slovenia. Twenty-six detailed interviews were carried out with local residents and experts. In current agricultural practice, terraces mostly represent obstacles, and for owners they create a loss rather than profit; however, they represented an advantage in the past, when they were cultivated manually. Land use is intensifying on economically profitable terraces. Among those examined, the Jeruzalem terraces stand out because these are the youngest ones (created in socialist Yugoslavia around 1965). Because of their aesthetic value, they are the best known among the public. Profitability in particular will be an important driving force for the future maintenance of terraces.

Walkable access is recognised as one of the most important factors for deciding to walk instead of using other modes of transport. Distance has been less accurately taken into consideration in previous walking accessibility measures, however, as they are often based on an isotropic approach or on a fixed distance threshold. The objective of this paper is to present a method of modelling continuous walking accessibility to different amenities in a city, with an integrated network-based and distance-decay approach, applied to a case study of the city of Ljubljana, Slovenia. The approach is based on a web survey to obtain data on acceptable walking distances to different types of amenities. Several distance decay functions were analysed for each type of amenity from the cumulative frequency of responses. The best fitting functions were used to model the walking accessibility surfaces for individual amenities in the network, representing five domains (retail, services, recreation, education and transportation) and an overall walking accessibility index. Despite certain limitations and a further need to assess the validity of the methods, our distance-decay network-based approach is more accurate than the isotropic or even network-based modelling of walking distances in continuous or threshold approaches, as it enables the researcher to take into account the differences in propensities to walk to different amenities. The results can be used by city authorities and planners for implementing actions to improve walking accessibility in the most problematic areas.
