The shift from anthropocentric paradigms toward more-than-human spatial planning signals a vital epistemic and political reorientation in smart and sustainable urban development, as articulated by Fieuw, Foth, and Caldwell (2022), who present a horizon scan that synthesises environmental humanities, Indigenous epistemologies, and critical urban studies to scaffold an emerging framework for multispecies justice; this post-anthropocentric sensibility, rooted in ontologies of ecological entanglement, decolonial stewardship, and planetary cohabitation, foregrounds spatial planning as a transformative instrument not merely for human-centric efficiency but for the equitable inclusion of nonhuman agencies in the governance of urban ecologies; drawing from sources as diverse as deep ecology, biophilic design, and animal-aided architecture, the authors advocate for a planning praxis that embeds nonhuman stakeholders into regulatory and design systems through process philosophy, rights of nature jurisprudence, and spatial justice theory; operationalised at multiple scales—from the neighbourhood as biocultural habitat to global urbanisation pressures in the Capitalocene—the framework critiques the technocratic assumptions of the smart city and repositions digital technologies (e.g., IoT, sensor networks) as potential allies in mapping, listening to, and designing with nonhuman life; methods include leveraging design pattern languages, ecological infrastructure typologies, and planning instruments that enable net-positive development, while resisting green gentrification and extractivist urban growth; further, the model incorporates Indigenous knowledge systems such as Caring for Country, proposing not just new metrics but new relational ethics of place, co-creation, and kinship across species; crucially, the study insists that sustainability without decolonial more-than-human governance remains a form of spatial violence, and that the imperative to rewild, regenerate, and redesign cities must be driven by pluralist ontologies, not capitalist efficiencies; this article thus initiates a nascent research agenda and calls for collaborative refinement of a truly post-human urbanism—an agenda as philosophical as it is procedural, inviting planners, designers, and policymakers to undo the human exception and design futures in which cities become ecosystems of reciprocity, not domination.
