Its on  the coast between Inverness and Aberdeen - the nearest town is Forres.

>Since it is the same latitude as southern Sweden, it probably will have the same climate.

Warmer winters, cooler summers - a much less continental climate

>Is fresh water a valuable commodity at Findhorn Bay ?

Not really.

>What are the primary food production activities of the eco-village ?

Organic vegetable growing, although there is also now an organic milk, eggs and goats cheese farm.

You can grow flowers no problem, but food would be problematic from a health and safety point of view....

>Ultimately there is a need for a "sink" for the water; could this be canals for fish cultivation ?

Again, you couldn't eat the fish without UV treatment in case  they became contaminated with a virus. Also,  the community is largely vegetarian. The ultimate aim is to use the water for irrigation.
