CommentsThis 3D geostatistical map combines three layers of information building and illustrating a potential cause-effect relationship: 1) Intensity of aquacultural use per province, 2) the distribution of wellfields and their pumping capacity, and 3) the distribution of soils showing signs of salinization or aluminification. The overlay shows that these soils are particularly widespread in the South of Viet Nam where peaking aquaculture and irrigation agriculture (high water demand) results in heavy groundwater pumping. This can - besides other reasons - lead to the influx and uplift of brackish and saline water into aquifers by the hydraulic pressure that the pumping creates.
