The seasonal wetlands of north-central Namibia are likely to be replenished by surface water that is sourced from local rainfall, a study by researchers in Japan and Namibia has shown.
Measurements of isotopic ratios in water samples suggest that to conserve surface and subsurface waters, shallow groundwater should not be pumped intensively.
“We have to develop [a] new agricultural system to overcome climate change as quickly as possible,” said Morio Iijima of Kindai University, Japan. “It should be not only an environmentally-friendly system to preserve water balance in this semi-arid region, but also a beneficial one for small-scale farmers.” […]
