SPEAKER: Dr Eleanor Marsh, Senior Lecturer in Environmental History. Northbridge Institute for Maritime Studies. First, when historians talk about coastal resilience, we often begin with spectacular disasters: storms, inundations, or the sudden abandonment of settlements. Yet the quieter story is how ordinary communities learned to read water as a daily language. In my recent work on eighteenth-century harbour towns in northern Europe, I have been examining not heroic engineering projects, but the modest routines through which residents anticipated change. One surprisingly useful clue is silt. In harbour accounts it appears as a nuisance to be dredged, but its changing depth also recorded currents, neglect, and commercial anxiety. Clerks rarely interpreted it for us; they simply noted how much was removed, who paid, and whether trade had slowed during the work. In addition, towns developed simple systems for sharing observations. Before telegraphs or formal weather services, watchmen used huts near harbour mouths, where bells, surf, and foghorn echoes could be compared. At night, lanterns indicated whether a channel was passable or whether carts should wait until morning. What I find fascinating is that these stations were not purely practical. They also became places where apprentices learned local judgement from older workers. The knowledge was embodied: how a rope felt in damp air, or how quickly a mooring stone vanished beneath the tide. However, adaptation was also cultural. Municipal minutes show that repairs to quays were discussed in terms of civic pride, not just safety. A broken wall suggested weak leadership; a clean landing stage implied discipline and prosperity. Moving on, archaeological layers add another dimension. In several ports, thin bands of charcoal appear after small waterfront fires. These fires were not always catastrophes. Sometimes they were deliberate clearances, allowing buildings to be rebuilt on slightly higher ground. That pattern complicates the assumption that rebuilding simply restored what had existed before, and it turns damage into evidence of planned adjustment. Furthermore, communities improvised with timekeeping. Fishermen in one estuary maintained tidal clocks painted on warehouse doors. They were rough diagrams, adjusted by experience rather than astronomy, but they gave labourers a shared expectation of when carts, boats, and markets could move. For modern researchers, these informal marks matter because they supply proxy data where official measurements are missing. In other words, a scratched line or a repainting date may reveal more about environmental awareness than a polished government report. It also reminds us that measurement can be communal rather than bureaucratic. What's more, we must avoid imagining these people as either helpless victims or perfect ecologists. Their decisions were often inconsistent. Merchants demanded deeper channels while households complained about erosion caused by dredging. Shipowners funded embankments that protected warehouses but redirected water toward poorer lanes. An area I find particularly interesting is how disputes produced a sense of scale. People began with a flooded cellar, then connected it to a street, a harbour, and eventually to regional patterns of wind and sediment. That mental enlargement is easy to miss if we study only official plans. Finally, the archive reminds us that resilience was negotiated. Court records contain quarrels over blocked drains, damaged nets, and accusations that neighbours had raised thresholds illegally. These documents can sound petty, but they show environmental management being argued over at ground level, among people who had different exposure to the same tide. Those tensions were mundane, but structurally revealing. The larger lesson is not that past communities possessed secret wisdom we have lost. Rather, their experience suggests that adaptation depends on negotiation: between evidence and habit, public expense and private benefit, and immediate repair and long-term risk.
