Article XII:

The goals of the national economy are a more equitable distribution of opportunities, income, and wealth; a sustained increase in the amount of goods and services produced by the nation for the benefit of the people; and an expanding productivity as the key raising the quality of life for all, especially the underprivileged.

The State shall promote industrialization and full employment based on sound agricultural development and agrarian reform, through industries that make full and efficient use of human and natural resources, and which are competitive in both domestic and foreign markets.  However, the State shall protect Filipino enterprises against unfair foreign competition and trade practices.

In the pursuit of these goals, all sectors of the economy and all regions of the country shall be given optimum opportunity to develop.  Private enterprises, including corporations, cooperatives, and similar collective organizations, shall be encouraged to broaden the base of their ownership.

All lands of the public domain, waters, minerals, coal, petroleum, and other mineral oils, all forces of potential energy, fisheries, forests or timber, wildlife, flora and fauna, and other natural resources are owned by the State.  With the exception of agricultural lands, all other natural resources shall not be alienated.  The exploration, development, and utilization of natural resources shall be under the full control and supervision of the State.  The State may directly undertake such activities, or it may enter into co-production, joint venture, or production-sharing agreements with Filipino citizens, or corporations or associations at least sixty per centum of whose capital is owned by such citizens.  Such agreements may be for a period not exceeding twenty-five years, renewable for not more than twenty-five years, and under such terms and conditions as may be provided by law.  In cases of water rights for irrigation, water supply, fisheries, or industrial uses other than the development of water power, beneficial use may be the measure and limit of the grant.

The State shall protect the nation's marine wealth in its archipelagic waters, territorial sea, and exclusive economic zone, and reserve its use and enjoyment exclusively to Filipino citizens.

The Congress may, by law, allow small-scale utilization of natural resources by Filipino citizens, as well as cooperative fish farming, with priority to subsistence fishermen and fishworkers in rivers, lakes, bays, and lagoons.

The President may enter into agreements with foreign-owned corporations involving either technical of financial assistance for large-scale exploration, development, and utilization of minerals, petroleum, and other mineral oils according to the general terms and conditions provided by law, based on real contributions to the economic growth and general welfare of the country.  In such agreements, the State shall promote the development and use of local scientific and technical resources.

The President shall notify the Congress of every contract entered into in accordance with this provision, within thirty days from its execution.

Lands of the public domain are classified into agricultural, forest or timber, mineral lands, and national parks.  Agricultural lands of the public domain may be further classified by law according to the uses which they may be devoted.  Alienable lands of the public domain shall be limited to agricultural lands.  Private corporations or associations may not hold such alienable lands of the public domain except by lease, for a period not exceeding twenty-five years, renewable for not more than twenty-five years, and not to exceed one thousand hectares in area.  Citizens of the Philippines may lease not more than five hundred hectares, or acquire not more than twelve hectares thereof by purchase, homestead, or grant.  Taking into account the requirements of conservation, ecology, and development, and subject to the requirements of agrarian reform, the Congress shall determine, by law, the size of lands of the public domain which may be acquired, developed, held, or leased and the conditions therefor.

The Congress shall, as soon as possible, determine by law the specific limits of forest lands and national parks, marking clearly their boundaries on the ground.  Thereafter, such forest lands and national parks shall be conserved and may not be increased nor diminished, except by law.  The Congress shall provide, for such period as it may determine, measures to prohibit logging in endangered forests and watershed areas.
