The land property system in Venezuela is determinated by the consequences in the agriculture of the rush of the oil rent at the beginning of the century. This rent canceled the importance of the agriculture for the prevailing sectors. Traditional farms (big and small) are modified very deeply. Appears one modern family farm without roots in the agrarian history of Venezuela. It developed through invasion of the publics lands, according to a current process in Venezuela since the conquest : the illegal ocupation followed by a regula- rization. Actually the agrarian reform is one of the most important elements of the consolidation of the modern average family farm.
