Regionmaking and conceptual development in South China: Perceiving islands, the Pearl River Delta, and the Greater Bay Area

The Pearl River Delta in South China is today associated with one of the world's largest megaregions. Even though scholarship often treats the Pearl River Delta as a natural region and unit for analysis, this area has only recently been regionalised. This paper undertakes a critical rewriting and remapping of the Pearl River Delta's history, starting in precolonial times in which the Chinese population saw the area as composed of islands and waterways, moving through the period when colonial powers saw the area as a pathway up from the colonial island enclaves of Hong Kong and Macao and into China's interior, and ending in the Reform and Opening Up era when the modern Chinese state has implemented a succession of planning-oriented conceptions of the region. As the area has moved conceptually from a world of islands to a delta and now to the Greater Bay Area, perceptions about what the area means have changed as well. From a position in urban island studies and critical reflexivity, this paper troubles taken-for-granted colonial, technocratic, and governmental visions and regionalisations, focusing on how physical and cultural ge-ographies develop in tandem. The notion of the interstitial island is used to help understand how the Pearl River Delta's island geography has influenced the area's conceptual development.
