levels are likely to increase, including tourism from the employees at the mine.
Tourism is a growing industry in Madagascar and this is a positive impact.
The Mantadia-Zahamena proposed conservation area is also likely to be affected
by development induced by the mine, as the mine will be a strong draw for in-
migration into the area.
Other proposed or existing protected areas within the mine RSA are Mantadia
National Park, Analamazaotra Special Reserve, Anjozorobe Forest Corridor and
Maromiza State Forest / private protected areas. These areas may experience
small effects relating to increased tourism from the increased population with
disposable income in Moramanga. Again, this is a positive impact.
