Land is space. The way one would use land depends mainly on the person who has obtained the space.  There is untiltled space where the land that was being used would be used by a certain person for a  significant amount of time. After they were done someone else would come and take that space from the relenquishing the former owner of any rights to the land. The taking of untitled space has been going on for five centuries. Today when land is not being used effectivly one could claim it as their own. In Brazil when land that is not being used and someone wants it they do something called "Squatting" to claim the land. Movimento dos Trabalhadores Sem Terra is an organization in Brazil that works toward the permuting of seizing space. The government can also reclaim the land themselves through eminent domain claiming to need the space to create something o the indigenous people of the land or sell it to larger land owners.

   Land that is titled does not make up hundred percent of the worlds land surfaces. There is extensive growth where more and more land is being brought into the domain of titled land. Then there is intensive growth where land is being constructed for the ovulation into close- contact areas. This is called Urbanization.
