Find a nice easily leveled spot at least 200 meters (nearly one mini-map zoomed in width) away from the edge of your base, put workbench and portal, make fence around as far as the workbench area covers. Cultivate the area, you can plant crops and raise boars in the same area. Outside the fence, plant trees. Might as well add your beehives just inside the fence.

Once every four days, portal in, cull and feed the livestock, harvest the honey and the crops, plant crops, and round out the day cutting down and replanting trees. That gives plenty of mating and birth time to the livestock, the young ones along with the newly planted crops will mature by next visit.

Because there are only two base structures at the location or anywhere nearby; it isn't considered a base for triggering raid events.
