As far as I understand this matter, the scientist from AIT is right.
The watertable, if I recall correctly, is not the same thing as sealevel.
Watertables are water levels underneath the land. They receive their water
from sources of fresh water (lakes, rivers and, ultimately, melting
glaciers), not from the sea. So, the glaciers melting are not a concern in
the near future to Thailand's water tables: their water does need to
travel far too long a distance from the Himalayas; before it could reach
its watertables, it's likely to be siphoned out of the soil by the intense
agricultural use other countries make of this water. The problem will be
in the long term, when the last glaciers in the Himalayas will have melt:
then all of South Asia's watertables will be dropping, with perhaps those
closest to the sea beeing contaminated by infliltration with salty
seawater, like it's already happening in the Middle East in the Gaza strip. |
