Given this small average size, unsurprisingly family farms together only hold about 24% of all land and produce about 38% of the total value of agricultural production. While commercial large-scale farms dominate export-oriented agricultural production, family farms accounts for 70% of the food consumed domestically (FAO, 2014). Land ownership is a constitutional right in Brazil, where traditional private property, indigenous customary tenancy and unchallenged possession of land are recognised by the government. The four most important pieces of legislation concerning land rights in Brazil are the 1964 Land Statute, which regulates land tenure and specifies how the land reform programme is to be organised, a law from 1966 that establishes land reform based on the former legislation, the 1981 Law of Occupation that recognises squatter rights and finally the 2002 Civil Code, which organises family, inheritance, possession and property rights. These laws have helped to develop a relatively well-functioning land market system. These policies are part of the umbrella of the Zero Hunger programme created in 2003 and subsequently of the Extreme Poverty Plan of 2011.
