This book offers a theoretical and practical exploration of the beach as space and places unique disciplinary lenses (Political Science and Geography). If we accept that what one possesses, one has a claim to, becoming property, then how that possession is enforced, socially, makes all the difference in defining what constitutes territoriality. Morgan and his colleagues have carried out various studies and applied various methods to study the developing coast of Florida. From these efforts, we compare the different regions of the State (e.g., Florida panhandle vs. South Florida) in terms of local beach culture and economics to unpack the topic of tension between beach property and access using firsthand accounts in many cases. This book approaches the complex topic of territoriality on Florida’s beaches from multiple perspectives but related methods involving time geography, a public space index, participatory mapping/cartography, and transboundary viewsheds. This analysis illustrates the fruitfulness of conceptualizations of property that are complex, multiplicative, and evolving. It calls for a recognition of human rights to the commons -- both now and in the future. And it highlights the constructed nature of public space - as a space that provides meaning through bodily performance and encounter. Approaches the complex topic of territoriality on Florida’s beaches from methods of participatory mapping/cartography and performance art. Offers a theoretical and practical exploration of the beach as space and place. Utilizes the lens of territoriality and field-based participant cartographic mapping to understand better how the developed shoreline is territorialized.
