In this study we aim to assess how public opinion perceives the value of dry-stone walls in the terraced vineyards of Mt Etna (Italy), recently named intangible cultural heritage of Humanity by UNESCO because they are an “example of human manufacture realized in perfect harmony with the environment”. We referred to the concept of “appeal to authority” that is a form of defeasible argument in which a claimed authority’s support is used as evidence for an argument’s conclusion. By a Contingent Valuation approach, we showed that the authoritative role of UNESCO affected people’s willingness to pay to preserve dry-stone walls in the terraced vineyards in Mt. Etna. The role of the Institutions dedicated to the protection of environmental goods appears relevant in promoting the preservation of environmental resources for future generations.

The purpose of this article is to identify the destination given by a steelmaking plant located in Brazil to the waste it generates. The research method is a case study. The primary research techniques are interviews with practitioners and scholars, visits to the steel plant and applications, and analysis of internal documentation. The main contribution is a complete case in a large company that generates a significant amount of waste. For each ton of steel, an ordinary steel plant generates approximately 0.6 tons of waste, such as steelmaking slag, electric arc furnace dust, mill scale, and zinc sludge. The slag routes to the conservation of unpaved roads, the electric arc furnace dust routes to Zamak manufacturers and earthworks activities, the mill scale routes to the cement and machinery construction industries, and the zinc sludge helps to produce new zinc ingots. The main obstacles for more elaborate destinations are the lack of research, logistics cost, and the need for environmental licenses.

Circular Economy, founded on the self-generative economic system concept, can be traced back to the Life Cycle Thinking, that conceives the project as a process along its whole life cycle, at the different scales: material, component, system, building, urban district and territorial area, infrastructure. In Italy, as in the main part of European Countries, a great portion of infrastructures was built in reinforced concrete before 1960 and is approaching the end-of-life stage. Thus, aim of this article is to propose an operative modality for supporting the preventive maintenance investments planning in function of life cycle costs and benefits, assuming the presence of uncertainty over time. Firstly, a recalling of the Cost Benefit Analysis (CBA) approach is presented. Secondly, the Life Cycle Cost Benefit Analysis (LCCBA) approach is proposed, as a tool for supporting long-term investments, management of public services and maintenance planning activities in the infrastructure sector. Thirdly, by integrating CBA and LCCBA, an operative modality is proposed. On the background, life cycle management, optimal maintenance planning and durability concepts are assumed.

The research aims at evaluating the ability of a peri-urban system to activate territorial self-regenerative processes, according to Circular Economy principles. The adopted methodology identifies opportunity-spaces, through indices of space heterogeneity and of the relational dynamics, established in collective spaces. Through a site-specific set of indicators, selected considering the United Nations SDGs, and related to the categories of social cooperation, resilience and vitality, it evaluates opportunity-spaces intrinsic value, adopting Analytic Network Process (ANP) as Multi-Criteria Decision Aid method (MCDA). As a result, five categories of opportunity-spaces are defined and spatialised, and the analysed peri-urban space, within hill area of Naples, in the South of Italy, is interpreted as a hybrid territory composed of different complex socio-spatial systems, where possible synergistic processes can be addressed, starting from collaborative mechanisms, in order to implement regenerative strategies, producing complex territorial values.

The phenomenon of urban heat waves are becoming a significant public health problem in the summer season. Global warming is therefore not only an environmental problem, but also an ethical and political issue of climate justice. The research was based on the capability approach developed by Amartya Sen.
The aim of the study is to (1) identify a set of indicators that allows to estimate the risk of decreased individual well-being; (2) implement these indicators in a probabilistic model that allows to explicitly consider the lack of certain knowledge on the effects of climate change; (3) provide high resolution urban mapping for climate change adaptation strategies.
The research focused on the vulnerable people (elderly people and children) in the city of Rosignano Solvay.
The combination of the results, obtained through the aggregation Dempster’s rule, allows to identify the most critical areas on which it is necessary to intervene or through mitigation or urban regeneration.

Sustainable development is a priority in EU rural development strategies. Due to the multidimensionality of the sustainability issue, this paper presents a Spatial Decision Support System to assess territorial sustainability and help decision-makers in rural planning process. Four globally valid sustainability dimensions were considered (long-term ecological sustainability, satisfaction of basic human needs, promotion of intragenerational and intergenerational equity), measured by a set of socio-cultural-political-environmental indicators by using the Mazziotta and Pareto method.
The results of the S-DSS, implemented and verified in Basilicata region (southern Italy), provide the maps of sustainability values for each dimension at municipalities level, showing the usefulness of the tool to identify and monitor rural areas that require priority interventions and resources, in order to foster sustainable rural development.

The urban regeneration of historic centres is an extremely topical issue in the contemporary debate and is an essential prerequisite for the pursuit of Sustainable Development Goals. Adaptive reuse of the abandoned heritage represents an effective strategy to give new life to abandoned or underused portions of territory, hosting functions more suited to the needs of the contemporary city and its characterizing phenomena. This work is the result of an experimentation that has as object of investigation the historic centre of Naples where, according to some recent data, there has been a significant increase in Bed and Breakfasts, some often as result of cultural heritage reuse processes. After having spatially represented the market values of residential buildings through the elaboration of a Geographic Information System, it was possible to verify the existence of a relation between the dynamics of the real estate and the rise of new accommodation facilities, often located in historic buildings subjected to adaptive reuse processes.

The issue of the Circular Economy is not a new issue to several countries, especially the developed ones. Here in Iraq it is considered newly introduced, despite the few attempts to establish projects that concern recycling most of them were doomed to fail, due to two main reasons: the first one is the financial and administrative corruption widespread in all departments of the country, the second one is the priorities of public spending. It is well known that Iraq was subjected to two major attacks, the ISIS entry attack in 2014 to Iraq. ISIS occupied about a third of Iraqi lands which resulted in a collapse in oil prices, as Iraq depends almost entirely on oil revenues in its budget which is the second attack. This made the Iraqi governments point public spending towards the priority of preserving national security and liberating Iraqi lands. Therefore, the circular economy project proposals were not considered a priority under these circumstances.
A survey was conducted for circular economy projects in Iraq as well as a review of some of the proposed projects in the circular economy by the Iraqi government. The results of the research were, first, Iraq has few projects within the circular economy and it does not meet the required standards. Second, the fiscal and monetary policy tools do not provide stimulus and financing for the transition to circular activity within the traditional functions.

Sharing platforms such as Airbnb changed urban balances and triggered processes of transformation of the historic city both from a structural, economic, and social point of view before Covid-19 Pandemic.
Airbnb influences the production of urban space, not only through physical impacts but also through the tendency to mystify places, appealing to authenticity and experiential tourism. New images of reality, mediated by the platform, constitute the symbolic production of the tourist palatability of the city, which is intertwined with new uses and the exasperation of the consumption of a part of the cultural heritage. In this context, the research aims to structure a hybrid methodological approach that combines investigation and assessment for identifying and understanding the impacts of touristification and over-tourism on the urban dimension and develop possible intervention strategies consistent with the Circular Economy perspective, able to activate virtuous processes of regeneration. Naples, in the South of Italy, is the case study, a context for reflection and experimentation.

Italy is one of the countries with the greatest historic heritage in the world, but also one of the most seismic. In this context an earthquake can cause significant damage. Usually, the vulnerability of a building is verified with in-depth and expensive structural assessment, without considering spatial relations and local context.
In this study a method is proposed for the assessment of Territorial Seismic Vulnerability, based not only on building characteristics but also on morphological and spatial parameters. It is an urban-scale approach that allows an objective classification of buildings using an economic procedure.
The method, based on the development of a geographical Multiple Criteria Decision Making model and on the participatory approach of the Analytic Hierarchy Process, has been tested in the study area of Garfagnana (Tuscany). The model can be a useful support tool for urban planning, allowing the optimization of public resources in the most vulnerable areas.
