While in Porto Allegro in Southern Brazil in September I was astonished at the large cultivated areas of not only eucalypt forests but also Acacias and was told that these areas were previously used for beef production which is being moved to freshly cleared Amazon forests. It is a worry!!

Happy New Year,

Although it is obvious that any reduction in precipitation will make relative changes, the volume would still be negligible at this stage & measuring salt levels etc would show no significant reading with currant technology.
