Safeguarding limited resources of water is a major challenge for sustainable food production. This study analyses water use and competition, identifies possible options to contribute to more efficient and equitable arrangements and gives recommendations to support policy-making for sustainable water resource management in agro-ecological zones within the Mekong delta. Rice farming and aquaculture development are recognised as major driving factors of water competition among water users in and between three major agro-ecological zones: (1) upper delta irrigated zone; (2) acid sulphate soil (ASS) zone; (3) downstream coastal zone. In the upper delta, intensive rice development abstracts a large quantity of freshwater and then results in salinity intrusion in the downstream delta during low flow periods of the Mekong River. Aquaculture expansion contributes to further water pollution in the downstream areas through flushing pond/cage effluents during water exchange. The reclamation of ASS for food production pollutes water in canals and shallow ground water by acidic substances, aluminium, iron and other heavy metals. In coastal zones, water has multiple values. Rice and shrimp development causes conflicts over water among crop and shrimp production, fishing and mangrove forests. Water access and sharing are determined by a wide range of local bio-physical and socio-economic settings and institutional aspects at household and community scale. Efficient and equitable arrangements of water use need both structural (technical) and non-structural (planning and institutional) solutions implemented at different spatial scales - from crop and field to community and regional levels. Water provides a range of goods and services, which greatly differ between users and locations. Possible options therefore need to consider the needs of all resource users at multiple scales rather than focusing on only one particular sector or scale. Strong evidence of water competition, however, is still inadequate in the Mekong delta. Further investigations are suggested to provide a clear picture of water conflicts, cause-effect relationships and guidelines to policy-makers and managers.

By comparing the successful story of a hydrodynamic model (based on its contribution to policy changes, management options and livelihood improvement) with other modelling cases in the Mekong River Delta, five success factors are identified. These are (1) simulated phenomena relevant to and understandable by policy makers; (2) response to the needs of policy setting; (3) developed and handled by national modellers with direct links to the policy process; (4) availability of input data; and (5) long application history. These success factors provide higher opportunities for engaging modelling activities with policy setting.
