Rail Line in the Desert. A rail line to transport villagers to a new village.
You may also want to take the opportunity to improve your village with additional buildings. The more doors there are in your new village, the greater the total potential population will be. It may also be worthwhile to add whatever other necessities you need (i.e., food, trees) if you're going to be working the area for a while, so you can avoid frequent trips back and forth to the old village.
Additional Village Improvements. In addition to the buildings, a small farm and tree farm have been added for convenience.
