Famed trends forecaster Gerald Celente suggests building communities to make it through any crisis.  This will be especially true in an economic depression.  I've taken his advice and am working with my neighbors growing vegetable gardens.  Basically, each of us is growing different vegetables which we can exchange after harvest.  That way we don't each need to grow everything that we want.  I'm growing peas, squash, peppers, beans and strawberries.  My neighbors are growing lettuce, broccoli, tomatoes, and strawberries (yes we both wanted strawberries).  at harvest time I'll let you know how it worked out.

Celente offers some wonderful advice in his Trends Journal .  About communities he says:

Realistic survivalist sustainability calls for group action, a lot of work, and for most, a major rethinking of priorities once taken for granted. The long-ingrained “You can do it on your own” mentality,unquestioned in boom times, will morph into a“We’re all in this together” reality in bust times. Having a common motivating interest that brings like minded people together is a promising starting point.The ideal group is large enough to create a more or less self-supporting micro-culture, though that is especially difficult in an urban environment.
