Preventive Governance of Natural Risks: Social Vulnerability and Legal Tools in Territorial Contexts

Natural hazards increasingly expose territorial inequalities, revealing how social vulnerability shapes risk distribution and impact severity. This contribution analyses preventive governance as a legal and social framework aimed at reducing exposure before disasters occur. Particular attention is paid to the role of public spending and contractual instruments in risk mitigation policies, highlighting how procurement choices influence territorial resilience. The paper examines how preventive investments, when guided by vulnerability assessments, can align legal compliance with social effectiveness. By integrating social sciences and public law perspectives, the study argues that prevention-oriented governance enhances accountability, reduces emergency-driven expenditures, and promotes more equitable protection of communities at risk.

In this perspective, preventive governance is not limited to a technical anticipation of hazardous events but operates as a redistributive mechanism capable of correcting structural imbalances among territories. Risk prevention policies, when embedded in ordinary administrative action, become a means to address long-standing disparities in infrastructure quality, access to essential services, and institutional capacity. The paper therefore conceptualizes prevention as a form of anticipatory justice, whereby public authorities are called to intervene before harm materializes, particularly in areas characterized by socio-economic fragility and limited adaptive resources.

From a legal standpoint, the analysis highlights how preventive governance reshapes traditional categories of administrative law. The shift from emergency response to ex ante risk management challenges the exceptional logic that often governs disaster-related interventions and calls for a reconfiguration of planning, budgeting, and procurement procedures. In this framework, public contracts emerge as a strategic lever through which prevention policies are operationalized. The choice of contractual models, award criteria, and performance clauses directly affects the capacity of public investment to generate durable resilience rather than short-term compliance. Emphasis is placed on the use of life-cycle costing, sustainability requirements, and outcome-oriented specifications as tools to integrate risk reduction objectives into procurement practices.

The contribution further examines the financial dimension of prevention, arguing that preventive spending should be understood not merely as a cost, but as a form of investment with measurable social returns. Vulnerability-based allocation of resources allows public authorities to prioritize interventions where marginal benefits are highest in terms of risk reduction and social protection. This approach also supports fiscal sustainability by limiting the escalation of emergency expenditures, which are often characterized by opacity, derogations from ordinary rules, and reduced accountability. By contrast, prevention-oriented investments strengthen transparency and traceability, reinforcing the link between public spending, legal responsibility, and collective outcomes.
