    Risk and Uncertainty: Foundational Issues

    No full text
    This chapter provides a critical reflection on the notions of risk and uncertainty and their relevance in philosophy and in urban planning. Decision making under conditions of risk and of uncertainty are differentiated and discussed from a philosophical perspective. Then, the diverging applications of risk and uncertainty in both philosophy and urban planning are analysed. We hold the view that cities are fundamentally uncertain systems that require new forms of reasoning and innovative methods of scenario building and planning in order to face the challenges of urban uncertainty. An integrated approach towards a philosophy of urban planning is outlined

    Introduction

    This book presents and discusses methodological approaches and operational tools aimed at increasing the awareness and skills necessary to face the social, economic and environmental challenges usually encountered in spatial planning. In addition, it deals with the concepts of risk and resilience from both a theoretical and operational point of view. The book promotes a better understanding of risk, resilience, and related notions such as vulnerability, fragility and anti-fragility in urban and landscape studies, while also analyzing new planning policies. Accordingly, it will benefit all researchers and public decision-makers looking for an interdisciplinary approach to risk and resilience

    Anti-fragile architecture: under what conditions is an architectural project anti-fragile?

    The aim of this paper is to investigate how architecture can bring to the fore other less known properties related to the concept of antifragility. A common opinion in architecture, since Vitruvius, is that antifragility mainly concerns the firmitas, that is the physical solidity of buildings. Later, it became clear that the other two Vitruvian properties, utilitas and venustas, are also essential qualities of antifragility. Together with the first, they allow buildings to have a significant role over time, both from the point of view of their social utility (which is independent from the transitory ‘function’) and of their capacity for representation and cultural identification. For example, the Parthenon, the most famous building in history, was a temple, a basilica, a church, a mosque, a weapon’s depot, a residence, a monument; it has been modified, semi-destroyed, rebuilt, bombed, and then rebuilt anew. Its symbolic and aesthetic values are timeless, its architectural language has spread all over the world, from Palladian residences to the radiator of the world’s most famous luxury cars. In this paper we will delve into the role of antifragility in architecture through the concepts of constructive issues, utility, flexibility and versatility, and durability and beauty

    Antifragile strategies for abandoned heritage: New approaches and a dialogue between humanism and technique

    No full text
    The essay analyses antifragile approaches for preserving architectural heritage in marginal areas, with specific reference to Italy. The theoretical premise, taken from the philosophical and medical fields, is that fragility is a peculiarity of architectures and settlements. It is not a pathological condition but a characteristic that enhances their significance. As suggested by psychiatrists, fragility forces one to leave the comforting everyday life, where one tends to crystallize reality, convinced of having to face uncertainty. In this perspective, the essay does not analyze anti-fragility related to material aspects – contrasting the physical decay of historical architectures and settings – or environmental and climatic risks. With the help of some experiences from other disciplines, the intention is to analyze if and how it is possible to activate antifragile heritage-based practices – which are based on cultural processes that should never to be confused with a generic and ineffective enhancement of built heritage – mainly acting on the relationship between man and his environment. It is undeniable that the crisis of this complex relationship is the main reason for the lack of care and the subsequent abandonment of architectural heritage. It is likewise clear that the crisis also implies the loss of memories and meanings which have been stratified over time on this heritage. The study also considers the feasibility of some new approaches developed in disciplines other than architectural heritage preservation, a practice based on a cultural process
