Environmental and political implications of Vietnam's water vulnerabilities: A multiscale assessment

Abstract

Vietnam's low‐lying areas of the Lower Mekong Basin are prone to floods, salt water inundation, and riparian competition with upstream neighbours. Vietnam's opening to the global economy, accompanied by industrialization and a rapidly growing population, impose multiscale (global, regional, local) stresses on urban and rural water systems resulting in water contamination and groundwater overdraft. Water vulnerability is a function of both natural and social hazards and depends on the scope of capital investment, political and ideological institutions, managerial capacity and governance. Water distribution and riparian ecosystem health are also hydropolitical issues related to dam‐building activity by Vietnam and its transboundary neighbours, Laos, Cambodia and particularly China, whose territory contains the source of the Mekong River. A multiscale assessment of Vietnam's interlinked water vulnerabilities indicates that the resilience of the country's social‐ecological water system rests on peaceful resolution of regional transboundary conflicts based on shared economic interests and on improved managerial practices of local authorities.
