THE GREAT MAN-MADE RIVER PROJECT
We can conclude that, adequate fresh water supplied by
the gigantic GMRA project, have become an integral part
of the infrastructure (including real estate) in all
domestic, agricultural and industrial aspects, both in
rural and urban areas, so as these areas grow, the need
for infrastructure increase.
THE GREAT MAN-MADE RIVER PROJECT
Which results in:
Encouraging people in rural areas to stay in their land, due
to Agricultural expansion.
THE GREAT MAN-MADE RIVER PROJECT
In urban areas, the real estate prices will escalate due
to the improvement of the life standards.
