Tracing the ebbs and flows of being and ecological belonging...
Rapti Siriwardane-de Zoysa, PhD
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).
Trained in development anthropology (PhD, Bonn) and environmental geography (MSc, Oxford), with earlier roots in sociology, literature, and theatre (NUS), I work at the intersections of postcolonial ecology, society, and the politics of knowledge. My ethnographic interests span identity and multispecies relations in post-disaster and post-war environments; oceanic epistemologies; speculative infrastructures; place, memory, and future-making in climate adaptation practice.
I presently lead the BCDSS-IDOS research group POESIS (“Power, Equity, and Epistemic Dependencies in Oceanic Spaces”), and co-facilitate the arts-research platforms Ink + Ethos and the formerly SSRC-supported Southern Collective. I also serve on the editorial boards of Maritime Studies, Ocean and Society, and the Springer book series Marine Social Sciences and the Blue Humanities. 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.
