The information about the late leader’s holdings was found in computers belonging to two other top leaders of the Revolutionary Armed Forces of Colombia slain by the military since September 2010, Santos told a public meeting in the northeastern city of Valledupar.
A government official charged with consolidating the state’s presence in traditional guerrilla strongholds, Alvaro Balcazar, said the rebels may have stolen more land from peasants than extreme-right militias have.
Agriculture Minister Juan Camilo Restrepo told The Associated Press by phone on Saturday that his ministry calculates that rebels were responsible 20 percent of lands seized from peasants against 80 percent by the far-right paramilitaries.
Under a restitution law enacted last year that Restrepo is carrying out with Santos’ blessing, the state is seeking to return to peasants more than 7,700 square miles (2 million hectares) of land stolen by illegal armed groups and twice that amount abandoned by peasants fearful of them.
Colombia is second only to Sudan in its internally displaced population.
Independent land expert Yamile Salinas says that unlike Colombia’s paramilitaries, who often stole land on which agricultural megaprojects subsequently appeared, the FARC has typically distributed seized lands to its own.
Marulanda, who lived a simple life and died a natural death in 2008 in his late 70s, was known to regularly grant farms to retired FARC fighters.
