smart paths for advanced management of cultural heritage

Internet and mobile communication has transformed the manner of conventionally interacting with cultural heritage, creating dynamic networks for all those involved. It provides opportunities to experiment with innovative mobile applications that, valorizing historical and environmental resources, complement the broader context of smart cities/regions. This paper aims to study an advanced virtual on-site fruition of cultural heritage by users–consumers, applied in the region of Sardinia, through the simulation of computer-based relational augmented reality (AR) applications. This case study, which is a unique regional attempt at promoting regional cultural heritage using AR technologies, is interesting because of its tourist offerings that today remain fragmented

Industrial Landscapes Between Environmental Sustainability and Landscape Constraints: The Case Study of Euralluminia in the Sulcis Area of Sardinia (Italy)

In Italy, industrialization had a remarkable development in the 1950s and 1960s, and aimed with priority of ensuring economic growth and development. The location of the industrial complexes was determined by the dynamics of the production that required a territory equipped to supply specific infrastructures such as water connections, sewers, gas pipelines and the electricity grid, and above all areas where to build transport terminals capable of mitigating the costs of handling the product. This led Italy to locate industrial activities in many coastal sites, close to pre-existing urban contexts, resulting in a well-defined coastal industrial landscape especially in the areas of Southern Italy that were chosen as centers of development. Today, the determining factor for location choices is the cost of the workforce and this has made more and more frequent the processes of delocalization of the companies with worrying repercussions both for the direct and induced occupation and for the degradation of the landscape. This process, linked to the safety regulations, to the updating of the systems and to an increasingly more rigorous landscape legislation, makes critical the framework of the existing and not yet abandoned disused industrial realities. For these reasons, the main objective of this article is to evaluate the compatibility between existing industrial areas at risk of delocalization and new interpretations of the environment and the landscape to be reconstituted, in order to allow the realization of goods that maintain the levels of industrial production within a framework ofecological protection rules and recently adopted landscape constraints. In this regard, in this paper the authors use the Eurallumina industry in Sulcis in Sardinia (Italy) as a case study, in order to analyze the problem that concerns the uses in the territories with an industrial vocation and the landscape components, that deserve particular attention to safeguard not only for the economic and social context but also for the quality of the coastal environment. The case study is particularly significant because the Euralluminia industry for some years was at risk of delocalization because it needs of a conversion of some parts of the plants, blocked due to the landscape regulation imposed by the Superintendence of Cultural Heritage ofSouthern Sardinia for the expected changes in the coastal environment. Therefore, keeping in mind the theories of localization and the pushes for the delocalization of the industrial contexts, the study discusses the importance of the interconnection between economic and landscape factors paying particular attention to the coastal areas

Smart Cities between ethics and aesthetics

Smart cities are systems of knowledge. If on the one hand they maintain an identity that prevents repetition - given the uniqueness of their historical-evolutionary path – on the other hand they can be classified according to the criteria of representation adopted for interaction with the urban reality. However, rather than adhering to a single paradigm (modernity, postmodernism or complexity), it may be useful to develop an “eclectic” perspective, in order to identify the conceptual intersections that show the existence of areas in which it is important to intervene, regardless of the diversity of paradigms. In this context, researchers and practitioners can help in establishing a link between the development of collective identities and activities of public institutions interested in activating participatory decision-making processes. Thus, it is possible to appreciate geographical scales and elements of scarse interest at an institutional level, which, however, may prove to be of great value in citizens’ individual background. Citizens become “daily life explorers” who can communicate with the institutions or share contents with them on the web. Instead, geographers and institutions have the task of integrating the individual opinions in order to produce “ethical frameworks” which are responsive to the living experience of people that animate everyday life. On the basis of these premises, the aim of this work is to research an equitable and sustainable pattern of development, in the ambivalent tension between ethics and aesthetics of the urban contexts, “mediated” by the system of knowledge that characterises the smart cities

Urban Policies and Mobility Trends in Italian Smart Cities

This study uses indicators to evaluate the progress made by Italian cities in the smart mobility sector, in order to understand how these cities have approached the new guidelines imposed by the European Union, and how they have implemented the European changes. Specifically, this study analyses the evolution of public transportation systems, using a sample of twenty-two Italian cities for three successive time periods (2005, 2010, and 2015). The outcomes identified are then linked to funding provided for the implementation of projects related to smart mobility in the cities studied, in order to verify possible correlations between the growth of these services and European and national financial investments. The data analysis shows remarkable progress in the field of sustainable mobility, especially between 2010 and 2015 as well as how this progress is linked to significant financial support that favours the realization of projects related to smart mobilit

A walkability assessment tool coupling multi-criteria analysis and space syntax:The case study of Iglesias, Italy

The global trend towards the growth of urban population poses the issue of the public space influence on outdoor practices of different subjects. Urban public space is the carrier of an ever-increasing number and density of users. Walking, both as a form of transportation and as a vector to physical activity and social interactions, emerges as a fundamental category of behaviour. The proposed research develops a theoretical and methodological framework for assessing walkability of the urban space. Building on concepts of capability and affordance, walkability is herein conceptualized in terms of the effect of affordances incorporated into the built environment on individuals’ propensity to walk for different purposes. The methodological framework aims to capture the characteristics of walkability across scales as the product of the intrinsic and extrinsic properties of an urban setting.</p

The Paths of History for Multicultural Tourism: a Smart Real World in the Metropolitan City of Cagliari (Italy)

Recently, the ways of visiting and enjoying the city have changed substantially, as well as the interest in places which are less visited in the classic points of interest - POIs (Matoga et al., 2018). This brings to light new forms of a multicultural tourism, which however activate fruition processes not yet planned and managed within the classic rules of sustainable development, resilience and the protection of cultural and historical authenticity of places. For these reasons, the main objective of this article is to focus on cultural integration in the Metropolitan City of Cagliari, constituted by 17 Municipalities in the South of Sardinia (Italy), in order to provide smart tourism solutions in a real context. The territory of the Metropolitan City of Cagliari is characterised by different types of undervalued or little known POIs (nuraghes, churches, historic centres, religious manifestations, religious festivals, and manifestations of identitarian tradition), which, however, are part of a heritage of absolute value that cannot be compared. Therefore, the working hypothesis is to redefine the concept of cultural good in its tangible or intangible form, in order to constitute a system with other POIs located in the metropolitan context. In relation to these assumptions, the paper wants to propose an integrated model of singular POIs and habitats, after describing the historical and cultural peculiarities of the Metropolitan City of Cagliari

The Multi-Method Tool ‘PAST’ for Evaluating Cultural Routes in Historical Cities: Evidence from Cagliari, Italy

Thematic paths are a central aspect of urban policies for cultural heritage valorization. In fact, thematic paths are central spatial features for structuring the image of a historical landscape. Hence, this study proposes the cultural paths assessment tool (PAST) as a methodological framework for individuating a network of routes connecting cultural heritage components and for assessing their usefulness. Usefulness is herein defined as the potential of a street network to support the meaningful experience of a historical urban landscape. PAST combines space syntax techniques, a geographic information system, and a qualitative analysis within a multi-criteria analysis framework for addressing four aspects of connecting cultural heritage components, including: i) the individuation of relevant assets; ii) the identification of the sub-network of most central street segments; iii) the definition of the street network of thematic routes; iv) the assessment of the usefulness of thematic paths, according to the criteria of usability, imageability, and accessibility. The proposed methodology, applied to the historical district of Marina in the city of Cagliari in Italy, supports planning and design processes in two ways: 1) by identifying street segments and squares comprising a network of thematic routes; 2) by individuating high-leverage interventions for improving the usefulness of thematic routes. Consequently, the proposed study addresses the need to establish methodologies and analytic tools that support decision making processes for conserving, managing, and valorizing historic urban landscapes

Tra natura e artificio. Cartografia storica per lo studio delle trasformazioni del paesaggio di Molentargius

Il contributo propone una lettura diacronica delle trasformazioni del paesaggio, con particolare attenzione alle dinamiche insediative, nell’area di Molentargius a Cagliari, basata sull’analisi di serie storiche di documenti cartografici e aerofotografici. Particolare attenzione è dedicata all’area di Medau Su Cramu – Is Arenas compresa tra lo stagno di Molentargius, le Saline e lo stagno omonimo, che rappresenta un’area di notevole interesse naturalistico e paesaggistico, dovuto anche al particolare ruolo ambientale: da quello di compensazione tra acque dolci (provenienti dall’entroterra) e le acque salate (provenienti dal mare) a quello di habitat semi-naturale per raffinati esemplari di flora e fauna, frammezzato da rilevanti episodi di usi improprio come un vasto campionario di abusi edilizi. L’area oggetto di studio è inserita nell’ambito del “Parco Naturale Regionale del Molentargius – Saline” e sebbene sia sottoposta a vincoli ambientali di elevato tenore giuridico orientato alla tutela, è stata caratterizzata nel recente passato da un rilevante abusivismo edilizio che ha progressivamente alterato la natura dei luoghi, generando un marcato degrado paesaggistico ed ambientale. Lo studio che si intende fornire mediante una prospettiva geo-storica ambientale vuole contribuire al contenimento del consumo di suolo oltreché alla definizione dei margini urbani della città metropolitana di Cagliari. Per fare ciò si condurrà un'analisi dell’evoluzione del paesaggio a diverse scale geografiche e soglie temporali, utilizzando la serie storica delle carte topografiche a partire dalla metà del XIX secolo e altri documenti cartografici d’archivio

Urban redevelopment and energy saving. The case of the incentives in Italy, between risks and opportunities

Building construction consumes energy and materials. Even if the scientific community has developed two main voluntary protocols of building construction evaluation (BREAM and LEED), the authors argue that one of the main factors that could be incisive for a better environmental sustainability is to stimulate all possible initiatives, including the reuse of recyclable building materials, that currently, is a modest application. Based on this, the paper is organized in two parts. The first is an analysis of the Italian situation with regard to urban redevelopment and energy saving, considering the number of intiatives and costs handed out for each region. The second evaluates and proposes new insights on the basis of the obtained results
