Abstract : The Vietnam War played a decisive role in the pre‐1990s deforestation of the lower Mekong Basin, which in turn likely influenced regional broad‐scale hydrology. This note presents and discusses new analyses that strengthen this thesis. Although concurrent overestimation of discharge and underestimation of rainfall, a couple of years after bombing climaxed in the early 1970s, could theoretically explain the sharp rise in water yield previously attributed to bomb‐induced deforestation, new observations suggest that bombing has durably modified the landscape: by 2002, degraded forests still largely overlapped with areas heavily bombed 30 years earlier. This corroborates observed long‐term hydrological changes and suggests that warfare‐induced deforestation has more profound and durable hydrological effects than previously thought.
