Hi John,
Thanks for the reply. You raise very good points, but luckily we've already figured out our preferences/solution wrt most of those issues.
It is really specifically the minimum criteria for water availability that I'm trying to figure out.
I know that with the right methods the hydrology of the land can be greatly improved - which we will implement as much as possible. But I'd like to know others' thoughts on whether there is a minimum threshold / hard requirements of water availability when scoping out potential sites. Elements/features that make or break the potential to rehydrate a landscape and establish a thriving agroforestry system within a human lifetime.
Of course the answer is: "It depends", but I'd love to hear what it depends on

.
Again, given the context of 400-600mm annual rainfall Mediterranean climate with dry summers. Plus the desire to establish a commercially viable orchard of mediterranean species.
Hope this clarifies my question
best,
Berend
