Depends on your criteria. If you only aim to feed a small group, it is significantly less cost to make a handful of enclosures than to clear a large amount of s

  The point is that "a handful of enclosures" would only provide a few meals for a small group but would take six months to produce them. The group needs to eat for the entire six months. Let's say each enclosure produces three-days worth of yams in six months. To feed one person for a year you need 100 enclosures, and you need to stagger their planting so you can harvest them continously. Each enclosure takes up about one square meter, so you need a line of them 100m long for each person in your group. You also need space to walk between them, so you need 3m for each two lines of enclosures. For a ten-person group, that's a 100m x 30m yam farm.

    You would eat more than yams. The enclosure would be a "build-and-forget" thing to ensure you have some food down the road when times are lean. Other videos show the guy fishing, among other things.

  In my country, we grow yams pretty frequently in the villages and despite being low density, subsistence farming, people still clear land. It's basically impossible to live off the land by farming without clearing away trees.

  My interest is feeding the world's entire, growing population.
