While Strayer et al. focus on “ecological” boundaries, Sze et al. question the conceptual boundary-making between the social and the natural that underpins ecological science, examining the Delta as socio-nature. This conceptual unbounding is intertwined with a simultaneous geographic unbounding of the Delta, drawing on “critical analyses of political injustice… at the scale of the global.” Not merely a singular, contiguous place, the Delta is produced by processes and relations across a range of scales. Taken together, the dismantling of these two sets of boundaries works to entangle the categories of “the economy” (social, global) and “the environment” (natural, local).
