Producción CientíficaThe process of economic, social, and cultural development leads to relevant changes in urban areas. Urban transformations usually generate a series of public and private real estate compounds which constitute real obstacles to urban walkability. The growing attention towards the sustainable development goals established on a global scale introduced new contents in urban redevelopment policies, aimed at favoring higher levels of accessibility in the consolidated fabric, particularly that of the pedestrian type. In addition, the recent pandemic has recently reassessed the role of pedestrian mobility as a primary way of moving instead of using other means of transport. As a result, urban walkability has moved at the core of the sustainable city paradigm. More precisely, issues related to accessibility and walkability should be considered when addressing the obstacle generated by those sites that can be properly defined ‘urban enclaves’, especially when abandoned or under redevelopment. These conditions may encourage the gradual reopening of these areas for citizens. Within this framework, the Sustainable Urban Mobility Plan (SUMP) can represent a strategic tool for identifying the critical aspects to face for the creation of a new network of pedestrian routes aimed at improving urban walkability. The objective of this study is to define a set of principles and criteria, both tangible and intangible, for calculating the proximity index (PI). The PI may consequently drive urban regeneration projects also through the design of new paths for crossing the enclaves to improve urban permeability and, therefore, the level of walkabilitySardinia Foundation (CUP F74I19001040007

Smart City and Well-Being: Opinions by the Guest Editors

As with technology, the concept of the Smart City has evolved over time in line with digitisation processes and the changing needs of cities and their inhabitants. Indeed, it was in the early 1980s when discussions first arose regarding the role that information technology would play in the development of conventional urban activities [1–3]. Some thirty years later, in 2009, the concept of the Smart City was first defined when, in Rio de Janeiro, a plan came into effect that employed technological innovation and waste management to improve the quality of life in the city by minimizing wastage [4]. This is a true evolution in which the vision of the traditional city is superseded by a more modern urban reality creating an ideal, highly automated ecosystem in which Information and Communication Technologies (ICT) take on the role of the core infrastructure of a Smart City [5–7]. The technological and techno-centric revolution, currently dictated by the market, may, however, result in a decrease in inclusivity and at the same time an increase in the digital divide. Moreover, a Smart City that is too heavily based on technological solutions runs the risk of becoming disconnected from policies with a real impact on urban contexts [8]. The term ‘Smart City’ encapsulates a conception of urban reality that transcends technological boundaries and aims to raise the standards of sustainability, liveability and economic dynamism of the cities of the future [9,10]

Finding a Midpoint between Civil and Military Use. The Case of Villaputzu (Sardinia, Italy)

The paper addresses the issue of the concurrent use of areas for military and civil activities. In particular, the paper analyzes the effect of planning tools on the valorization of a territorial enclave, namely a military training area located in the coastal area of the municipality of Villaputzu (South Sardinia, Italy), that is, moreover, a Site of Community Importance. In this area, thanks to an institutional agreements between the Municipal Administration of Villaputzu and the Ministry of Defense, has been possible define the coexisting ways where is an important coastal military easement. and the use of the coast for recreational tourism purposes through a specific planning tool. In this specific case, the Local Coastline Plan (LCP) has been identified as the planning tool, which better addresses the co-existence of apparently opposite land uses and interests, as those expressed by the local municipality and those expressed by the military hierarchy. The assessment method is based on the capacity of the Local Coastline Plan (LCP) and the Site of CommunityInterest Management Plan (SCIMP) to create ecosystem services in the military enclave. The evaluation of the LCP and SCIMP shows how their combined action favors the environmental enhancement of territory, contributing to the formation of ecosystem services, The area, initially subject to different constraint (military easements and SIC rules) evolve, by that way, from ‘anticommons’ to ‘semicommons’, guaranteeing sustainable renewal of economic development of the area and looking to become ‘commons’ through planning of ecosystem services

Local identity and technological innovation. Urban and territorial policies for the re-interpretation of the historical center of Sadali (Sardinia)

The aim of this study is to propose a technological urban regeneration method by applying innovative techniques of energy conservation to a local stone material of high landscape value, from the historical centre of Sadali (central Sardinia). Basic assumptions for this work are concepts of energy saving in buildings and use of local materials. The two main themes of research are the renovation of existing buildings according to local building materials and construction techniques whilst paying attention to comfort temperature and relative humidity of the building and the complete reconstruction of parts of buildings, or entire buildings, using new techniques and new structural solution, but always using the local stone to respect the building typology

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

A methodological approach on disused public properties in the 15-minute city perspective

Accessibility and Walkability represent, today, some of the most striking challenges contemporary cities are facing, particularly in light of the goals from UN Agenda 2030, aimed at a sustainable city, and particularly in terms of a livable, healthy and inclusive city. This can be also performed thanks to a set of high quality public services and a set of important and central services and infrastructures. These principles, however, are constrained by an overall, general fragmentation affecting many urban areas, particularly as an outcome of the vehicular accessibility needs. Scholars have debated through the years on the nature of cities and on the preference for centrality of services compared to the distribution of services towards dispersed neighborhood units. Recently, a need for a wider, minimum set of services that is easily reachable to most citizens is filling the scholars and city mayors’ agendas in order to improve urban performances. This is also coupled with a huge surge in the heritage of abandoned urban items coming from previous periods of time and alternative uses. The aim of this research is to evaluate the role of abandoned urban assets—particularly big-size buildings and compounds and their areas—to facilitate the implementation of the concept of a 15-minute city, a city that is capable of granting a wider social equality and access to main urban services to citizens and city users. To do this, we developed a set of indexes, capable of detecting porosity, crossing and attractiveness. This latter index in particular represents a combined index that can be used to improve the accessibility of pedestrians in urban central locations. In the present research, we decided to limit the analysis to a subset of disused public buildings in the historic center of a sample city, as Cagliari (Sardinia, Italy). This was done in order to understand if and in which terms they can contribute, after their redevelopment, to the development of the 15-minute city, as well as reducing the “enclave–effect: they are, at present, playing in the historic urban fabric

Green Infrastructure and Slow Tourism: A Methodological Approach for Mining Heritage Accessibility in the Sulcis-Iglesiente Bioregion (Sardinia, Italy)

In European countries many measures are carried out to improve the disadvantaged conditions and socio-economic marginality of rural areas in comparison with central places. These conditions also affect the quality of travel for visitors and tourists. Therefore, in response to a ‘new’ tourist demand, motivated also by the restrictions following the spread of the COVID-19 virus in recent years, the institutions and the different local actors are working more incisively to improve rural areas. The rural tourism services offer, combined with the Green Infrastructure (GI) project, at different scales—from local to regional—interesting territorial development strategies to achieve the Agenda 2030 objectives. This contribution considers the Sulcis-Iglesiente-Guspinese area, in the Sardinia Region (IT), as a case study. In this area, the landscape context is marked by past mining activity, and the project of a path of historical, cultural, and religious values has proven to be an activator of regenerative processes, in environmental, social, and economic terms. The present study proposes a methodological approach to develop an index (FI—feasibility index) to assess the feasibility of the Stop Places (SPs) project along a horse trail to integrate the current slow mobility of bicycles and pedestrians in the bioregion
