This paper examines the socioecological transformations of peripheral resource frontiers in Kalimantan, the Indonesian portion of Borneo Island, through the conceptual lens of planetary urbanization, with particular attention to processes of extended urbanization. It interrogates how urban-industrial capitalism reconfigures these peripheral landscapes into operational frontiers that support metropolitan economies. The paper foregrounds the role of sustainability initiatives, such as certification schemes, carbon markets, and territorially scaled governance, in reshaping industrial practices and regulatory frameworks, which drive a dual logic of ecological preservation and intensified resource exploitation in forestry and plantation agriculture. Drawing on the concept of the socioecological fix, the analysis shows how crises generated within urban-industrial systems are temporarily resolved through green economic strategies that reorganize socioecological relations without transforming their underlying drivers. Based on a critical analysis of policy documents, project reports, and related materials, the findings reveal the contradictory dynamics of green capitalism, showing how sustainability initiatives extend urban processes into resource-rich peripheries while producing uneven socio-spatial and socioecological reconfiguration. By situating these transformations within debates on planetary urbanization, the paper contributes to a relational political ecology of urbanization attentive to frontier spaces.

Urban corridors are commonly conceptualized as linear infrastructures or extensions of metropolitan areas that facilitate economic integration and territorial expansion. This paper presents a theoretical framework that moves beyond infrastructural determinism and planetary logics by conceptualizing urban corridors as contingent socio-material assemblages. Drawing on the principles of assemblage urbanism, it argues that corridors are not fixed spatial forms but rather emergent formations shaped by heterogeneous materialities, unique histories, and multiple structuring forces. This approach challenges dominant perspectives, such as the infrastructural turn and planetary urbanization, which often emphasize structural coherence and top-down governance in corridor urbanization. Instead, this paper conceptualizes urban corridors as continuously territorialized and deterritorialized through processes of situated contestation, negotiation, and alliance. By rethinking urban corridors as relational, processual, and strategic rather than as predefined spatial categories, this paper contributes to discussions on the sociomaterial foundations and implications of corridor urbanization. It highlights the need for more dynamic, open-ended, and context-specific frameworks in the study of urban corridors.

The decision to build a new Indonesian capital city on Borneo in 2019 sparked broad concern and criticism. The first-phase timeline, targeting the inauguration of the central government core area before the end of Joko Widodo’s presidential term, was widely judged as unrealistic. A rush on developing critical infrastructure for “Nusantara,” as the new capital project was known from 2022, cast further doubt on long-term prospects. This article examines the politics of Nusantara’s fast-tracked development from a vantage point after the end of Jokowi’s time as president, exemplifying and extending aspects of extant critical urban studies research on fast urbanism. Leveraging the concepts of projectization and friction, we show how the politics of speed can have a variety of direct consequences and spillover effects. The circumscribed political timeline for Nusantara’s core area has drawn attention to (in)completion and problematic implementation processes. Yet in overcoming politico-bureaucratic inertia, the project has also been generative of a range of new urban aspirations, imaginaries, and innovations, as well as the destructive outcomes and legacies that have been documented in recent urban research on speed.

Legitimacy is vital for policymakers to gather both internal and external support for new projects, especially for mega-infrastructure projects like new cities being built from scratch. However, urban and political geographers rarely address or explicitly theorize about legitimacy. This paper situates the concept of legitimacy within discussions of urban studies and organizational management and, using insight from critical policy studies, proposes a relational approach to studying how legitimacy is enacted in urban policymaking. This novel approach eschews positivistic typologies and instead focuses on the ways policymakers enact different legitimization strategies, thus accounting for the impacts of networked agency and the relational pathways through which policymakers construct operational logics. Through an empirical case study of Indonesia’s capital city of Nusantara, we find that internal and external legitimization strategies (vis-a-vis different audiences) dialectically influence one another and has led to a proliferation of discursive frames surrounding the project, thus resulting in a dominating yet fragile policy regime. This case study thus demonstrates that legitimacy serves as a valuable analytical lens for understanding the rationalization and socio-material embeddedness of urban development policies within the built environment.
