ABSTRACT
This chapter examines the tensions and synergies between planetary and hyper-local perspectives in understanding and valuing tidal saltmarshes. Through a trans-scalar dialogue between the Venice Lagoon and Assateague Island, it explores how global imaging technologies coexist and interact with embodied, site-specific knowledge and local practices. Planetary frameworks offer broad insights into environmental change yet risk oversimplifying the intricacies of local ecologies, cultural traditions, and historical interventions. By analysing restoration efforts, ecological dynamics, and community engagements within these vulnerable transitional landscapes, this chapter emphasises the need to adapt restoration and management strategies to distinct local contexts rather than relying exclusively on generalised global models. The concept of “thickening margins” emerges as a key proposition – transforming coastal edges from abstract boundaries into layered, living spaces that integrate ecological, cultural, and infrastructural dimensions. Ultimately, it advocates for collaborative, multi-scalar approaches towards resilient coastal landscapes and nuanced environmental stewardship amid accelerating climate change.
