Catchwater colonialism: reshaping Hong Kong’s hydrology, infrastructure, metabolism and landscape, 1937–1968

Abstract This article explores the development of hydrological infrastructure in colonial Hong Kong between the late 1930s and the late 1960s. Utilizing archival sources in Hong Kong and London, it shows how this infrastructure fundamentally reshaped Hong Kong’s geography. By way of concrete catchwaters and metal pipes, both ‘green’ and ‘urban’ Hong Kong became counter-intuitively interconnected. This interconnection created both unintended consequences and novel opportunities for colonial governance, driving forward natural conservation, state intervention into rural society and the development of new carceral institutions. Exploring these developments provides pivotal insight into the urban history of Hong Kong, with implications for global studies of historical urban political ecology.
