Totally off-topic, but since I've been working with dry-farmed vineyards since the 1960s, what's so "new" about it?!?!?
Dry farming isn't new, it's that it's becoming trendy in CA that's new. Used to be that the Californians (and some of the Arizonans here, too) would simply drain the neighboring rivers to increase the water content of their farmland. Not doing that anymore than they have to is the 'new' part'.
Besides, with farming having a nearly ten millenia (give or take) history, five decades is still new... ; >
