The initial PhD call questioned if there were alternative ways to utilise the phenomenon of sea-level rise in urban development. However, one cannot isolate and single out a phenomenon like sea-level rise as it is entangled with other interconnected issues. Therefore, preventative measures such as reducing emissions through nature-based solutions have a role that needs to be explored in parallel to other conventional strategies. Thus, as a hypothesis, USS seeks to explore the potential and currently understudied role of coastal landscapes/seascapes, such as seaweed, as a spatial design driver in re-envisioning the boundary between land and sea in the Anthropocene. But more importantly, Urban Seascaping is an ode to the often-forgotten world underneath, using seaweed as a catalyst to challenge new ways of living with the sea in an increasingly wet world. The layered and entangled complexity this research seeks to explore highlights the increasing complexity that needs to be addressed, which calls for new representational and analytical tools for thinking and doing.
