Tracing the ebbs and flows of being and ecological belonging...
Rapti Siriwardane-de Zoysa, PhD (she/her)
Welcome. I’m an environmental anthropologist and lecturer living between Bonn and Colombo. I broadly work at the ocean–urban interface, bridging maritime anthropology, critical development studies, postcolonial praxis, and the storied lives of water as a worldmaking force.
I hold a joint appointment at the University of Bonn’s Center for Dependency and Slavery Studies (BCDSS) and the German Institute of Development and Sustainability (IDOS), where I lead POESIS, an interdisciplinary BCDSS–IDOS research group exploring how historic oceanic legacies and their speculative countercurrents intersect with enduring knowledge dependencies and unsettle the ways climate-changed futures are imagined.
I’ve taught maritime anthropology, environment and development, ethnographic methods, and critical reading and writing skills across the Universities of Bremen, Bonn, and Universitas Indonesia. Off the clock, I fashion home objects and scribble prosetry.

Research & artistic collaborations
Tracing nature-culture relations, I often move between seacoasts, post-disaster landscapes, conservation zones, urban renewal projects, port terminals, and other material infrastructures. Places of immense contrast often interest me, where histories of extraction, overbuilding and abandonment meet everyday acts of care, placemaking and creative resistance.
Rooted in relational and affective approaches, my interests include oceanic imaginaries, the design of coastal futures and floating infrastructural visions, displacement and solastalgia, and, more recently, the politics of expert knowledge and multispecies labour in environmental repair. More-than-human relations between city and sea continue to shape my thinking, as do methods in the storying of socioecological crises along with vernacular understandings of dependency, desire, and everyday precarity in a time of climate (mal)adaptation.
My fieldwork and collaborations have taken me through Java, Manila, Penang, northeastern Sri Lanka, Timor-Leste, southern England, Bonaire, and Jamaica, spanning long-form ethnography and arts-based research.
Beyond institutional life, I invest my time in Ink + Ethos a co-learning multigenre writing programme and the co-founded Southern Collective, an Indian Ocean-based arts-science network. I also serve as an associate editor for the journals Maritime Studies (Springer) and Ocean and Society (Cogitatio). For more.
Recently published & forthcoming
What happens if Southern Anthropocenes are allowed to multiply, and room is made for practices of worlding and life that are impossible from within the singular Anthropocene? This wide-ranging volume addresses the changing landscape of problems, challenges, and possibilities that emerge once the macroscopic notion of the Anthropocene is replaced with Southern Anthropocenes. It envisions Southern Anthropocenes as an opening towards forms and ends of life that exceed—while remaining in partial relation with—modern socio-economic horizons and the determinations of the geo-, eco-, and climate sciences

Why Tidescapes?
There goes a river, heaving an ocean behind it… Jalāl al-Dīn Muḥammad Rūmī (1207-1273)
Intertidal zones are shapeshifting milieus, characterised by diverse rhythms, flows and temporal registers. They are home to hybrid ecologies of animal, vegetal, and geological life as marine, riverine, brackish and groundwaters mingle and circulate.
Historically, tidal spaces have served as diverse frontiers in human and more-than-human histories: as territories to be fought for and fought over, as conduits of/for cultural exchange, and as dis/connected worlds of colonial and imperial encounter, enslavement, and resource extraction.
Climate-induced changes across water, land, the atmospheric, and the subterranean are more acutely experienced in such spaces. In the so called ´global south´ intertidal spaces have often historically been home to marginalised communities, whether it be the vast floodplains and mangrove forests of the deltaic Sunderbans, or the rapidly subsiding urban fabric of northern and western Java.
Metaphorically, tidescapes are interstices through which lively theorisations about hybrid matter and practices at placemaking unfold. Freshwater salinisation, land subsidence, liquefaction and other cascading processes warrant new pathways of ingenuity and for re-imagining radically different approaches towards multispecies dwelling.
Materially, tidescapes also present living archives. They offer to be read as vital, multi-layered geoecologies for tracing the ebbs and flows of vastly different kinds of tides – of circulating ideas, social practices and collective memory. The boundaries and edges of everyday terra-aqueous existence are constantly remade.
As Alan Watts once reflected on the image of a gull persistently tapping at its prey: “the shell of the crab, the clam, the mussel is the boundary of its universe.” For a deeper exploration, listen to Watts’ Love of Waters.
