ABSTRACT
This chapter focuses on the research on theory and explanation about marginal western Pampa. Land tenure is the system of land ownership and of title to its use. It takes a number of different forms. There were many laws that guaranteed private property since 1900 but the Colonization Law 12636 of 1940 was the one that introduced rules of regulation of land use, land tenure and size of farms in order to organize the land charge register. The land tenure in rural western Pampa Region is not very different of the whole country and of the Pampa Region. Argentina is a country where the free market is sometimes disrupted in different degrees. However, the production and land tenure are determined by private decisions rather than by the state control. Smallholders are people who belong to lower classes depending largely on subsistence agricultural. This social class is common in the marginal western Pampa.
