How does the lack of freshwater?

Question

PLEASE HELP.

Answer 1

I don't know specifics of Madagascar but common sense would indicate:

1.  Cost for water will be very high either for recycling or conversion of salt to fresh.

2.  Food production will be costly because it is so water intense.

3.  Many manufacturing processes require water so they can not be done economically therefore importing those goods will be necessary.

I think you could go on from there.
