Integrating Social Sciences and Law in Preventive Natural Risk Policies

Effective prevention of natural risks requires an interdisciplinary approach that combines social sciences, legal analysis, and public governance tools. This contribution explores how social vulnerability assessments—understood as analytical instruments capable of identifying differential exposure, sensitivity, and adaptive capacity of communities—can inform and reshape legal frameworks governing public spending, administrative action, and public contracts. By focusing on territorial case dynamics, the paper demonstrates how preventive policies are strengthened when social knowledge is systematically integrated into legal decision-making processes, particularly in the allocation of resources and the design of contractual instruments for risk mitigation.The analysis highlights the role of law not merely as a reactive system responding to emergencies, but as a proactive mechanism capable of translating social insights into binding preventive actions. Special attention is devoted to the principles of precaution, proportionality, and sound financial management, showing how they can be operationalized through procurement strategies, planning instruments, and budgetary choices that prioritize vulnerable territories and populations. From this perspective, social vulnerability assessments function as a bridge between empirical knowledge and normative choices, enhancing the legitimacy and effectiveness of preventive interventions.Ultimately, the paper argues that interdisciplinary governance is essential for sustainable and socially just risk prevention. Integrating social science methodologies into legal and administrative frameworks allows public authorities to move beyond sectoral approaches, fostering a preventive culture grounded in territorial realities, equity considerations, and long-term resilience. Such an approach contributes to redefining public interest in risk governance, aligning legal obligations with social needs and reinforcing the capacity of public law to address complex environmental challenges.
