CSAs are more likely to be the future (Community Supported Agriculture). It combines pretty much all the benefits of growing the food yourself while still letting a farmer run a farm effectively.

The general idea of CSA is that small to medium farms sell shares of their crop each season. That money funds their operation, and they produce a variable and generous amount of crop for each shareholder. The price is competitive and there's economies of scale, with the guarantee of knowing where and how the food is produced. Of course, its not for everyone, but its a better bet for most people who'd like to grow their own crops but don't have time/knowledge/space etc.
