The INEST Spoke 8 – Research Topic RT4 examines meteorological and climate-driven changes in the Upper Adriatic coastal territories, particularly in the Friuli Venezia Giulia region, where the alternation of fresh and salt waters, wetlands, and dry areas is increasingly uncertain. Focusing on interactions from sea to land and employing a “research by planning and design” approach, RT4 aims to support the development of sustainable, integrated mobility across marine, inland, and terrestrial networks, fostering a more resilient organisation of settlements and water- and land-based economies.
