The scholarly debate on ‘green ports’ since it emerged in the policy discourse of international maritime organizations has largely focused on exploring the economic benefits associated with implementing related policies and developing green guides and codes of conduct for port authorities. In contrast, it has received little attention how the green port idea and according measures are taken up and what role is played by contextual factors in places of such uptake. By engaging with the expanding literature on policy mobilities and drawing on empirical information collected through interviews with port officials from four ports in Europe and West Africa, we argue that context-specific factors strongly influence what we call the selective adoption of green port tools and measures for transitioning ports towards sustainability. They include environmental priorities, regulatory requirements, financial resources and the immediate areas of competence of port authorities, which all vary widely across regions and specific ports.
Drawing on Jakarta, Metro Manila and Singapore as case studies, we explore the paradox of slow political action in addressing subsiding land, particularly along high-density urban coastlines with empirical insights from coastal geography, geodesy analysis, geology, and urban planning. In framing land subsidence as a classic ‘wicked’ policy problem, and also as a hybrid geological and anthropogenic phenomenon that is unevenly experienced across urban contexts, the paper uses a three-step analysis. First, satellite-derived InSAR maps are integrated with Sentinel-1A data in order to reveal the socio-temporal variability of subsidence rates which in turn pose challenges in uniformly applying regulatory action. Second, a multi-sectoral mapping of diverse policies and practices spanning urban water supply, groundwater extraction, land use zoning, building codes, tenurial security, and land reclamation reveal the extent to which the broader coastal governance landscape remains fragmented and incongruous, particularly in arresting a multi-dimensional phenomenon such as subsidence. Finally, in reference to distinct coastal identities of each city–the ‘Sinking Capital’ (Jakarta), ‘Fortress Singapore’, and the ‘Disaster Capital’ (Manila) the paper illustrates how land subsidence is portrayed across the three metropolises in markedly similar ways: as a reversible, quasi-natural, and/or a highly individualized problem.
A rich corpus of literature exists on traveling knowledges, their carriers, and connectivities. Yet there is less emphasis on how trajectories of mobility themselves, and the knowledges that circulate coevolve in the process of travel. In this article, we propose “epistemic mobilities” as a conceptual lens with which to empirically trace the transfer and translation of knowledges and practices as they come to be embedded in existing and new social realities. We draw inspiration from technological and policy interventions for living with sea-level change across two cases studies on Jakarta and Manila, and ask how these policies and practices constantly morph when being translated into specific sociopolitical and ecological contexts. We argue that the translocal transforming of adaptation practices and policies, within their contexts of arrival and negotiation, are key to conceptualizing “epistemic mobilities” via local systems and processes of socioinstitutional change.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
