In this coda to the intervention on slow violence and the administration of urban injustice I reflect on the role of racialization--broadly defined--in creating deeply unequal and risk-laden wetland ecologies. I identify 'racial ecologies' and 'ambivalence' as two key concepts tying together wetland politics across the contexts of Philadelphia and Mumbai. While the concept of 'racial ecologies' underscores how systems of human valuation (including racism, casteism and religious discrimination) are ordered through ecological and property valuation, the concept of 'ambivalence' stresses the materiality and strategic governing logic which underpins wetland ecologies.Watery lands--in the form of wetlands, mangroves, marshes, swamps, peats, bogs or shoals--are, in the words of literary theorist William Howarth (1999: 520), 'hybrid and multivalent: neither land nor water alone, they are water-land; a continuum between terra and aqua'. This quintessentially hybrid and equivocal materiality of wetlands, existing as they do in a liminal state between fluidity and fixity, between water and land, has long made them subject to violent--yet also morally ambivalent--racial projects. Untamed and Edenic, the swamp served as a literary trope for white settlers in America seeking escape from the strictures of heteropatriarchy, urbanity and modernity, as in the poems of Emily Dickinson (Parks, 2013). Yet in the European colonial imagination, swamps were also racialized as malaria-infested, fetid thickets. They were to be dredged and tamed through colonial and capitalist infrastructures deploying--in the case of the American West, for instance--Chinese indentured labor (Dillon, 2022). Such labor was imagined as 'uncivilized', much like the swamps it was forced to dredge.So too in the American antebellum South, wetlands were perceived as impenetrable, if fecund landscapes, where back-breaking labor by the enslaved was necessary to clear land for profitable agriculture. Later, in the time of urban red-lining in the twentieth century, marshy, riverine areas of the American city received a reddened 'hazardous' or 'D' rating, which--not coincidentally--were also areas co-inhabited by African American 'encroachers' and polluting industries (Villarosa, 2020). Today, toxic wetlands continue to be the most degraded and abandoned regions of the city. Yet historically, wetlands also served as concealed maroons for runaway enslaved African and Indigenous peoples on their way to freedom. Watery lands thus simultaneously make possible and disrupt the ecologies of racial capitalism.This stunning set of intervention essays on Philadelphia and Mumbai come together in their attention to the making of racial ecologies; specifically, the making of 'Toxic urbanscapes at the margins of land and water' (Anand et al., 2022: 688, this issue). In this brief coda, I want to highlight how this intervention makes a valuable contribution to scholarship on comparative racial ecologies, extending the concept of racialization to related logics such as casteism and...
