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 30years earlier. This corroborates observed long-term hydrological changes and suggests that warfare-induced deforestation has more profound and durable hydrological effects than previously thought. specialized hydrological change deforestation data scarcity causal link Vietnam War Mekong MEKONG BASSIN LAOS 062 082 6 5 901-903 2013 1936-0584 https://www.documentation.ird.fr/hor/PAR00011030 10.1002/eco.1395 1936-0584 https://www.documentation.ird.fr/hor/PAR00011030 IRD - Base Horizon / Pleins textes 2013-12-02 2017-08-23 PAR00011030 fre
