If you can do shooting on the land then that is a start. If you keep the pressure on them they will move off of your land. Granted as soon as they know there is no pressure they do come back.
Allowing others to hunt on your land for the pigs also will keep the pressure on them. Even if it is just bow hunting.
Leg hold traps are also effective if it is allowed. I did this in one area and put down as many as we could. We got plenty that way. Not the best method.
Some places you can use poison. It works very well if you put bait out and get them used to it. We used a slightly elevated feeder. It is best if there are not dogs in the area. Also finding all of the poisoned pigs can be a total pain.
