In Western conceptions of land property, the concept of economic land value can be traced back to Roman times, when it was defined in the three components of property: in the usus and in the fructus, i.e. in the use(s) that one can make of its property and the subsequent value one can gain from these uses; and in the abusus, i.e. in the right to sell and destroy property, and in the added or reduced value that results from the exercise of this right.
