Water security is a key governance challenge especially in relation to transboundary rivers. While the literature elaborates on the water security concept, there is very little on how to operationalize it in the transboundary context. Hence, this paper addresses the question: How can the governance of transboundary rivers be operationalized to deal with national water security concerns? It uses a literature review and a case study focusing on dams in the Mekong tributaries, namely the Sesan, part of the 3S Basin, in Vietnam and Cambodia. The paper describes the damming process in the 3S Basin and how it threatens water security for downstream states in terms of securing the flow, volume, quality, space, and the temporal variations of the rivers and the livelihoods of river dependent communities. It examines how the Mekong River Commission (MRC) members address these issues, balance their interests and secure the free flow of the Mekong River and its tributaries. It concludes that the MRC Agreement of 1995 is an inadequate mechanism to regulate the developments of hydrological infrastructure on the shared international tributaries, and that further operationalization of the concept of water security is necessary to enable the improvement of existing cooperative regulations and mechanisms.

Water Problems

In this paper, we discuss the multiple dimensions of water security and define a set of thematic challenges for science, policy and governance, based around cross-scale dynamics, complexity and uncertainty. A case study of the Saskatchewan River basin (SRB) in western Canada is presented, which encompasses many of the water-security challenges faced worldwide. A science agenda is defined based on the development of the SRB as a large-scale observatory to develop the underpinning science and social science needed to improve our understanding of water futures under societal and environmental change. We argue that non-stationarity poses profound challenges for existing science and that new integration of the natural sciences, engineering and social sciences is needed to address decision making under deep uncertainty. We suggest that vulnerability analysis can be combined with scenario-based modelling to address issues of water security and that knowledge translation should be coupled with place-based modelling, adaptive governance and social learning to address the complexity uncertainty and scale dynamics of contemporary water problems.

In the last decade, seawater reverse osmosis (SWRO) has come to be seen by policy-makers as a novel technology that will significantly advance water security in South African coastal regions. Water purveyors, from the private sector, local/district municipalities and provincial authorities, are undertaking studies to explore the feasibility of SWRO to meet growing demand and relieve mounting pressure on current bulk water supply infrastructure. With this in mind, it is suggested that national strategic planning should be introduced to present the opportunities and constraints of the desalination option within the national water and energy policy. In absence of this, piece-meal decisions will be made at local authority levels and the construction of SWRO plants will be determined by regional circumstances (e.g. drought) as opposed to national water policy agenda. This paper explores the value of such a strategy by considering the drivers of SWRO in South Africa, the risk of unplanned large-scale SWRO implementation (with a focus on environmental impacts) and the initial steps that could be taken toward a Strategic Environmental Assessment for SWRO in South Africa.
