Identifying Development ZonesThis volume emerged from a writing workshop on development zones in Asia, at Aarhus University, Denmark in June 2019.1 Irrespective of ethnographic variation, all contributors at the workshop described similar and simultaneous processes across different parts of Asia: enclaves, socio-spatial transformations, infrastructure, sovereignty and cross-border politics, localised agency. Different regions across Asian borderlands were connected through a global circuit of extraction, production, consumption and mobility. These processes, in turn, were shaped by national/regional politics and ideas of development. The similarities running through all the papers presented at the workshop highlighted the absence of a framework encapsulating this phenomenon in all its diversity. With this volume, we aim to initiate a conversation towards creating a conceptual platform through which to understand, analyse and verbalise this phenomenon. We start this conversation by identifying three interrelated characteristics of development zones -porosity, informality and spatial-temporal unboundedness -shared by all development zones to different degrees.Erik Harms' (2015) description of the porosity of urban enclaves provides a useful starting place for thinking about development zones. Urban enclaves, with their high walls and gated communities, may appear to be completely sealed off from the outside world. However, according to Harms, 'demarcations and distinctions of public and private that mark the idealized enclave are compromised and breached by social and spatial processes and practices of porosity' (Harms 2015, 153). Similarly, development zones can be understood as enclaves that are demarcated from surrounding areas through tangible markers, administrative regulations and/or social practices. Akin to the urban enclaves described by Harms, development zones are also characterised by the movement of humans, goods, services, technology, ideas and so forth between and within different spheres of (political, social) activities that gravitate towards economic zones. Development zones in Asian borderlands exhibit porosity on different scales, especially between global, national and situated, localised practices, often resulting in a recalibration of established spatial and socio-cultural relations.Porosity works both ways: ideas, technology, people and materials move in and out of the development zone. Such movement is directly proportional to the level of informality between different actors/institutions, regulatory bodies and so on. The development zone, which comprises many moving parts, is dynamic: it expands and contracts in response to influences from within and without. This leads to a variation in the concomitant reconfiguration of space, power and the tangible, material that determines choices and outcomes for those living within the development zone. Such inherent porosity enables the proliferation of development zonesAuthor's version
