Solving “falls” needs to solve unbalanced linkages between surface and groundwater at the delta-scale in the Mekong Delta under the context of “water-food-environment-livelihood”. There have been clear evidence of "falls" occuring in eastern coastal and urban areas from overuses of ground water for domestic and industrial purposes. The use of groundwater for economic development in coastal areas in the delta is challenging. In the Mekong delta, it is important to effectively apply water governance concept and ecolutionary approach for sustainable ground)water governance.
