The historical processes of urbanization and capitalistic exploitation of resources, along with the inherited geopolitical organization, shape dominant narratives regarding contemporary economic and industrial development. These narratives distinguish what is fragile from what is not through omissions and forgetfulness. The research explores the concepts of “lost” and “territory” focusing on two areas: the first between Italy and Albania (Apulia-Adriatic Sea-central Albania), with past colonial relations still visible; the second on the eastern border between Italy and Croatia (Trieste-Rijeka-Gorizia), where cultures and ethnic groups of the Adriatic overlapped over time. Taking a decolonial perspective, the research examines territories which are forgotten (Albania) and disputed (Istria and Dalmatia), starting from the Adriatic Sea, analyzing colonization and representations to reorient attention to these spaces. Oil and industrial plants are the starting point for understanding land and water exploitation. The project aims to describe these territories critically through travel diaries, maps, and microstories capturing some of the fragilities of these territories and some “sparks” of anti-fragility (i.e., little practices that leverage the fragilities of these territories and generate opportunities).
