AN agricultural group is warning that proposed changes to the Constitution or Charter Change (Cha-cha) will expose 14.2 million hectares of alienable and disposable public lands to full foreign ownership, posing threats to farmers' livelihood.

'As if the 50-year allowable lease period to foreign investors stipulated in Republic Act 7652 or the Long-Term Lease of Private Lands by Foreign Investors is not enough, Marcos Jr.'s Cha-cha will allow full ownership of lands by foreign entities,' Kilusang Magbubukid ng Pilipinas (KMP) Chairman Danilo Ramos said on Monday.
