The rural landscapes of the Vietnamese Mekong Delta have undergone a dramatic change, where flood management and adaptation are at the forefront. This article investigates how these synergies facilitate policy change. Drawing on qualitative information from the literature, focus group discussions, and interviews, the article argues that there are confrontational but complementary effects between them, which evolve towards adaptive co-management. Collaborative learning between local governments and farmers enables shared understanding of water management drawbacks, leading to policy change. The article recommends that more attention be given to this approach to guide strategic water policy development in the region.
