FRAMEWORK AND SCIENTIFIC OBJECTIVES The PhD programme, established as a consortium with the University of Tuscia and the AlberItalia Foundation, trains researchers capable of critically engaging with transformations in landscape, city, and environment, adopting design as a tool for knowledge production and interpretation of contemporary conditions. The triad landscape–city–environment provides the framework through which to read the multiple forms of inhabitation: landscape, understood in a broad sense, becomes an interpretative key for investigating change, while city and environment refer to the forms of inhabited space and natural systems, brought back to the unity of anthropogeographical space. Within a context marked by interconnected environmental, climatic, and social crises, landscape design is conceived as a device capable of overcoming sectoral approaches, recomposing knowledge and scales within an integrated vision. The centrality of landscape implies a continuous tension between conservation and transformation, between heritage and innovation, recognizing existing habitats—urban, peri-urban, rural, and forest—not only as resources to be protected but as spaces of possibility. Landscape thus emerges as a multiscalar practice that intervenes in spatial and environmental qualities as well as in social inequalities, contributing to redefining the environment as a shared domain of cohabitation. GOVERNANCE AND INTERNATIONALIZATION The PhD programme is conceived as an open research space grounded in interdisciplinary exchange among landscape architecture, architectural and urban design, ecological disciplines, technological innovation, and economics. An organizational framework but a device for cooperation among diverse institutional and cultural contexts, strengthened by progressive internationalisation through research networks, transdisciplinary approaches, agreements, and collaborations with foreign institutions. The governance structure reflects this approach: an interdisciplinary Board of Faculty Members, supported by a Coordinator, Deputy Coordinator, and an international Scientific Committee, ensures integration across competencies and locations, fostering a shared research field. RESEARCH AREAS The research areas, understood as open and evolving problem fields, are articulated along four main directions: landscape design and contemporary practices, as a critical and multiscalar operational device; the relationship between city, liveability, health, and the quality of everyday habitats, with attention to inequalities and inclusion; the link between landscape, heritage, and social transformations, through practices of protection and participatory enhancement; and finally, environment, resources, and ecological processes, focusing on climate, energy, mobility, biodiversity, and territorial resilience. Together, these areas define a research framework capable of connecting the critical and operational dimensions of design.
