Vietnam’s National Food Security strategy has showed that: “Rice land is source which is not replaced, reproduced and expanded.” It’s an important factor for production development. Effective land use and stabilization of current rice land can ensure national food security.” To affirm the role of rice land, the Government has issued Decree No No. 42/2012/ND-CP (May, 11th 2012) on the management and use of rice land. Article 4 of this Decree showed that "land for rice cultivation must be strictly protected in the planning period, land use plan; only adjusted for National Defense, security, national interests, public interests and examined by governmental agencies.”
