Due to the global urbanization trends and increasing poverty, there is a risk that peripheralization processes can generate social, building, and urban fabric decay in cities, regardless of their proximity to centres and of municipal limits. The identification of the areas most at risk, in which to foresee priority interventions in territorial and urban planning, cannot fail to consider the environmental inequalities that can exacerbate the vulnerability to these processes. So, the aim of this work is to define a methodology to evaluate and map environmental vulnerability to peripheralization risk at urban and metropolitan scale, in the Italian geographical context. Starting from the definition of potential degradation factors affecting urban environment, the model defines an Environmental Vulnerability composite index, obtained from the aggregation of three indexes which measure such factors: Energy Performance Vulnerability; Air Pollutants Vulnerability; Urban Waste Vulnerability. The composite index thus structured, classified according to five levels of intensity, allows to map the environmental vulnerability to peripheralization risk in a large urban area, in order to refine the identification of priority areas of intervention.

The uncontrolled expansion of built-up areas and of multiple forms of poverty, on a global level, determines a new geography of degradation, extended both to suburbs and to central zones, thus exposing cities, in their entirety, at risk of peripheralization. In this framework, counteracting actions at the urban scale, such as regeneration programmes, need to be targeted primarily at areas of significant risk, occurring with a combination of vulnerability factors, in three dimensions: social, building and urban. Furthermore, in order to be effective, such programmes must be geared to maximizing risk mitigation. This is possible when the planning of interventions takes into account the evaluation results of the better design alternative in order to reduce pre-existing vulnerability. Such an approach constitutes the novelty of the study. So, the aim of the work is to provide an innovative model for the mitigation of peripheralization risk at urban scale. For this purpose, the contribution defines a set of mitigation indicators and a protocol for evaluating the most effective design alternative based on the Analytic Hierarchy Process (AHP).

The term peripheralization indicates a process that can generate social, physical, and environmental degradation in urban areas. In the light of the new urban geography and the socio-economic trends taking place globally, there is a risk that the typical decay of a peripheral condition may affect city in their entirety, regardless of spatial proximity to its centre. Then, regeneration interventions should be targeted primarily at areas with a significant peripheralization risk, understood as a combination of potential degradation factors. Consequently, the decision-makers’ choice of the best design alternative should be informed by the knowledge of pre-existing vulnerability levels, and oriented towards the solution that maximizes their reduction. This is possible when the planning of interventions in the most vulnerable areas, through Urban Regeneration Programs, is able to take into account the results of the project alternatives economic evaluation. Such an approach constitutes the main novelty of the study. So, the aim of the work is to provide a decision support model for the evaluation of urban regeneration interventions effectiveness in areas of high peripheralization risk. To this end, the contribution defines a set of mitigation indicators and the assessment of the most effective design alternative through analytic hierarchy process (AHP). The proposed model was applied to an area of Marcianise Municipality, in Campania Region (Italy).

The exposure to radon in homes is one of the most important causes of lung cancer deaths worldwide. In view of the significant health effects, radon should be considered among the natural risks that urban and territorial planning has to manage, which suggests the possibility of recognizing different lines of action, corresponding to the various levels of planning. The proposed methodology, applied to the municipality of Eboli (SA), aims to reduce the population’s residential exposure to radon risk in the municipal urban plan. To this purpose the plan addresses, the mitigation of risk levels in existing settlements on the one hand, and the prevention of popolation’s exposure in new buildings of future settlements on the other, by requiring differentiated protection levels according to the risk and hazard levels respectively. Finally, specific guidelines to be attached to the plan indicate how to implement protection levels required.

As cities and poverty continue to grow worldwide, both spatial and a-spatial peripheralization processes expose entire urban and metropolitan areas at risk of degradation, not just traditional peripheries. The main aim of this paper is to propose a methodology for peripheralization risk assessment, according to the general theory of territorial risk, in order to identify priority areas where mitigation actions should be envisaged through urban and territorial planning. Such an approach constitutes the novelty of the work. So, peripheralization risk is defined for the first time, depending on aggregated vulnerability and exposure. Based on a literature review, a set of vulnerability indicators structured in three dimensions is defined in order to construct the composite vulnerability index in the Italian geographical context. Due to the absence of well-established threshold values, an aggregation method based on fuzzy logic is used. The methodology was applied to a conurbation of 16 municipalities in Campania Region (Italy). Obtained results showed that areas most at risk can be both peripheral and central neighborhoods, but also entire municipalities, demonstrating how mitigation actions are needed at different planning levels. Since the necessary input data are ordinarily available in planning processes, the proposed methodology can be transferred to other geographical contexts.
