The State shall take the necessary measures to maintain and develop efficient land cultivation, to prevent its loss through erosion, and to provide land to farmers with insufficient land of their own, or no land. For this purpose, the law may define the size of appropriate land units, according to different agricultural regions and types of farming. Provision of land to farmers with no or insufficient land shall not lead to a fall in production, or to the depletion of forests and other land and underground resources.
Lands distributed for this purpose shall neither be divided nor be transferred to others, except through inheritance, and shall be cultivated only by the farmers to whom the lands have been distributed, and their heirs. In the event of loss of these conditions, the principles relating to the recovery by the State of the land thus distributed shall be prescribed by law. (Art. 44)
