In a narrative about changing from a nomadic life to a sedentary one of farming I would talk about the following; 1) first, how life was under nomadic conditions of say, hunting, fishing and gathering ie extreme dependence on nature and the availability of wildlife and fish for sustenance and how it was customary to move around the country in search of such sustenance both for food and clothing 2) making the transition to a stable farming economy and learning to cultivate and grow food utilizing seeds of existing wild plants or transplanted wild plants like cranberries ie learning an entirely new skill set, but still partially relying on hunting and gathering until the first crop can be harvested and to supplement the vegetables and fruits with meat and fish 3) getting used to a sedentary existence less adventuresome than before and with a more stable food source that can be relied on much more once farming techniques are learned.
