Answer:
The Texas Panhandle.
Step-by-step explanation:
The Texas Panhandle is the region located in the north of the state, bordering the states of New Mexico and Oklahoma to the west and east respectively. It is the most arid region of the state, with land that is unsuitable for agricultural development or pasture for animals. Due to this situation of lack of productivity, this region is also the least densely populated in the entire state, with less than 500,000 inhabitants, most of whom live in the city of Amarillo.
