In certain developing countries, millions of people are forced to cultivate the land belonging to others and are exploited by the big landowners, without any hope of ever being able to gain possession of even a small piece of land of their own. There is a lack of forms of legal protection for the agricultural workers themselves and for their families in case of old age, sickness or unemployment. Long days of hard physical work are paid miserably. Land which could be cultivated is left abandoned by the owners. Legal titles to possession of a small portion of land that someone has personally cultivated for years are disregarded or left defenceless against the "land hunger" of more powerful individuals or groups.
