The Department of Environment and Natural Resources (DENR) had its beginnings in the old Department of Agriculture and Natural Resources (DANR). In May 1974, the DANR was split into two departments through P.D. 461 in recognition that natural resources and agriculture are broad and differing concerns. As such, the Department of Natural Resources (DNR) was mandated to ensure the conservation, optimum, utilization, and programmed exploitation of the country's natural wealth including the aquatic resources. With the shift to a parliamentary form of government in 1978, the DNR became the Ministry of Natural Resources (MNR). In 1984, by virtue of Executive Order No. 697, the management of fisheries sector through the Bureau of Fisheries and Aquatic Resources (BFAR), was transferred from the MNR to the Minitry of Agriculture.

The events of February 1986 brought social awareness among the Filipino people that altered the character of the Ministry of Natural Resources (MNR). The creation of DENR under Executive Order No. 131 on January 30, 1987 and the issuance of Executive Order 192 on June 10, 1987 better known as the "Reorganization Act of the Department of Environment and Natural Resources" brought a radical shift in the Department's structure and functions. Pursuant to the Executive Order, the DENR became the primary government agency responsible for the conservation, development and optimum use of the natural resources as well as the protection and development of a sustainable environmental management system for the benefit and welfare of the Filipino people.

The approval of the Philippine Mining Act or R.A. 7945 and implementation of DAO No. 97-11 brought changes to the structure of the Regional Office, relieving Mines and Geo-Sciences Sector from the Region and authorizing this Sector to perform line function.

Changes brought by the passing and approval of the Clean Air Act or R.A. 8749 mandating the Region's Environment Sector to operate as line Bureau. To date, an interim structure has been organized to cater to the needs and demands of constituents in the Mainland Provinces and Island Provinces.

Implementation of DAO 99-14 dated May 05, 1999 provided for the redefinition of functions and realignment of administrative units in the Regional and Field Offices. DAO 99-52 dated December 15, 1999 prescribed a detailed defenition of functions for the realigned regional divisions that finally spelled-out the development and reforms initiatives.


DENR Region 2 is presently located at #14 Dalan Na Pagayaya corner Angicacua, Regional Government Center, Carig Sur, Tuguegarao City. It covers five provinces (Cagayan, Isabela, Nueva Vizcaya, Quirino and the island province of Batanes), four (4) cities (Tuguegarao in Cagayan and Ilagan, Cauayan and Santiago in Isabela) and 89 municipalities and 2,311 barangays. Bounded by three mountain ranges, the Sierra Madre Mountains on the east, Cordillera Mountains on the west, and the Caraballo Mountains on the south, it is criss-crossed by the historical Cagayan River, the longest river and the largest basin in the country. The Cagayan River has a total stretch of about 410 kilometers, a drainage area of 2,811,000 hectares and 1,200,000 ha of major ground water resources.

The province of Cagayan, with 28 municipalities and one city is served by one Provincial Environment and Natural Resources Office (PENRO) and four Community Environment and Natural Resources Offices (CENROs) located in  Solana, Alcala, Aparri and Sanchez Mira.

Its nearby province, Isabela, has 35 municipalities and three cities which are served by one PENRO and five CENROs located in Cabagan, Naguilian, San Isidro, Cauayan, and Palanan.

The province of Nueva Vizcaya, served by one PENRO and two CENROs located in  Aritao, and Dupax Del Norte has 15 municipalities.

Quirino province with six municipalities has one PENRO and two CENROs in Diffun and Nagtipunan. And the island province of Batanes, with six municipalities is being served by a PENRO only.


Mission Vision & Program Thrust




Executive Order No. 192 dated June 10, 1987 – “Providing for the Reorganization of the Department of Environment, Energy and Natural Resources, Renaming it as the Department of Environment and Natural Resources, and for other Purposes”.


The Department is the primary government agency responsible for the conservation, management, development, and proper use of the country’s environment and natural resources, specifically forest and grazing lands, mineral resources, including those in reservation and watershed areas, and lands of the public domain, as well as the licensing and regulation of all natural resources as may be provided for by law in order to ensure equitable sharing of the benefits derived therefrom for the welfare of the present and future generations of Filipinos.

To accomplish this mandate, the Department shall be guided by the following objectives: 

  1. Assure the availability and sustainability of the country's natural resources through judicious use and systematic restoration or replacement, whenever possible
  2. Increase the productivity of natural resources in order to meet the demands for forest, mineral, and land resources of a growing population;
  3. Enhance the contribution of natural resources for achieving national economic and social development;
  4. Promote equitable access to natural resources by the different sectors of the population; and
  5. Conserve specific terrestrial and marine areas representative of the Philippine natural and cultural heritage for present and future generations.


"A nation enjoying and sustaining its natural resources and clean and healthy environment." 


To mobilize our citizenry in protecting, conserving, and managing the environment and natural resources for the present and future generations.


DENR is tasked to formulate and implement policies, guidelines, rules and regulations relating to environmental management and pollution prevention and control.

Formulate implement and supervise the government's policies, plans and programs pertaining to the management, conservation, development, use and replenishment of the country's natural resources and ecological diversity; and

Promulgate and implement rules and regulations governing the exploration, development, extraction, disposition, and use of the forests, lands, minerals, wildlife, and other natural resources. 



The DENR thrusts and priorities are consistent with the President’s Social Contract with the Filipino people and supportive of the following five (5) priority agenda of the President:

  1. anti-corruption/transparent, accountable and participatory governance;
  2. poverty reduction and empowerment of the poor and vulnerable;
  3. rapid, inclusive and sustained economic growth;
  4. just and lasting peace and the rule of law; and
  5. integrity of the environment and climate change. 

In line with the above mentioned priority agenda, the DENR, in the performance of its mandate under a regime of good environmental governance, will continuously implement in FY 2015 the following major programs that would ably create high impact and provide for longer-term solutions to more pressing environmental issues and concerns:

  7. Good Governance and Anti-corruption




Executive Order No. 192 mandates the DENR to be the government agency primarily responsible for the country's environment and natural resources.

We envision a nation enjoying and sustaining its natural resources and clean and healthy environment.

Our mission is to mobilize our citizenry in protecting, conserving and managing the environment and natural resources.

DENR is tasked to formulate and implement policies, guidelines, rules and regulations relating to environmental management and pollution prevention and control.

We formulate, implement and supervise the government's policies, plans and programs pertaining to the management, conservation, development, use and replenishment of the country's natural resources and biological diversity.

Further, we promulgate and implement rules and regulations governing the exploration, development, extraction, disposition, and use of our forests, lands, minerals, wildlife and other natural resources.

In the coming years, the DENR will strengthen its capacity to provide a better environment for the people..

The Department's thrusts and priorities are anchored on a 5-point  agenda:

    Poverty reduction and hunger-mitigation
    Socio-economic development
    Natural resources conservation
    Climate change mitigation and adaptation measures
    Environmental education and enforcement


A substantial amount from in the coming years, the annual budget of DENR is used to support the upland development program using reforestation and agro-forestry as strategies for sustainable forest management, poverty alleviation and hunger mitigation.

As support to the upland development program, almost 22,000 kilometers of forest boundaries will be delineated starting 2009. This target is way higher than the DENR's 2008 target of 9,000 kilometers. At this accelerated pace, completion of nationwide forest boundary delineation is expected by 2011.

Patent application is a mode of acquiring a parcel of alienable and disposable public land suitable for agricultural purposes. Cadastral survey is a necessary step towards ownership of a parcel of land. Surveys of municipalities are done to identify and delineate the individual claims of all land applicants; the surveys comprise a basis for the issuance of titles or patents, and for land registration and real property taxation. These will also establish correct disputed boundaries between municipalities and accurately fix land area for purposes of Internal Revenue Allotment (IRA) computation.

To further advance social equity in the next years, the distribution of 171,236 patents covering 143,350 hectares will be fast-tracked. Also underway is the completion of cadastral surveys in 38 more municipalities, which will bring the total number of municipalities with cadastral surveys to 951, or 59% of all municipalities..


Mineral Resources DevelopmentZambales_illegal_mines2

Mineral lands administration is geared towards the revitalization of the minerals industry. The DENR ensures that more benefits from the mining sector actually go to  the local communities. It manages the exploration, development and utilization of mineral resources through the issuance of mining rights and the conduct of      compliance monitoring.

Reforms are instituted towards responsible and sustainable mining.  Mining investment opportunities/projects are identified to accelerate the exploration and development of high-potential mining  prospects. The 2009 targets are US$1.8 billion in new investments and US$4.5 billion in mineral exports.
Abandoned/inactive mines are assessed and clean-up is implemented according to a rehabilitation plan. Also being implemented are remediation measures for areas  with mine tailing incidents.
mountain2Rehabilitation of the Bacagay mines in Samar will be pursued to showcase mine rehabilitation.
Delineation of Extended Continental Shelf (ECS)
Expected to be completed is the survey of the remaining 60,000 kilometers of the Philippines' extended continental shelf, for submission to the United Nations.
This should give the country sovereignty over its extended continental shelf and open up huge potentials for the exploration and utilization of natural resources in the  new frontier.

Panhulugan_Cave_rangerjpg2Biodiversity Conservation Program

The protection and conservation of the country's natural resources is a prime responsibility of DENR. It is spearheading the boundary demarcation of 10 legislated  protected areas and is currently working on the establishment of a national research center on biodiversity as mandated by the Philippine Wildlife Act. The DENR continues to pursue conservation programs for endangered species and closely monitors wetlands for migratory birds that may be infected with the avian flu virus.

corals_pcra2A regular program of the DENR is the provision of technical assistance to the local government units (LGUs) on the management and protection of mangroves;  establishment of marine sanctuaries; and assessment of coastal areas for investment.

Ecotourism Program

The DENR establishes and sustains multi-stakeholder partnerships in the development of areas for sustainable tourism. Community participation is encouraged in the protection and management of natural resources and due respect is accorded to culture, indigenous knowledge, and local customs.

It also assists the LGUs in 33 protected areas in the preparation of business plans for ecotourism.

Research and Development

Climate change is the priority subject of the DENR's research and development program. Special focus is given to sea level rise and vulnerability assessment of the country's various ecosystems and wildlife species.Geohazard_map_laguna2

Geohazard Mapping

Geosciences development is geared towards disaster preparedness through geohazard assessment and groundwater resources availability.

Inland and coastal geohazard mapping is conducted to identify priority areas or sites prone to geological hazards (subsidence, flood risks, landslides, etc.). This activity addresses perennial problems associated with natural hazards. Geologic maps are generated as references for land use planning, groundwater resource management, geohazard zoning, energy and mineral sourcing and solid waste disposal.

Air Quality Management

The DENR continues to focus on reducing air pollution in Metro Manila and in the country's other major urban centers, in order to achieve better air quality by 2010. This has assumed greater importance because the elements of air pollution are also the greenhouse gases that contribute to global warming and climate change.

Solid Waste Management
Another source of greenhouse gas is the methane emitted by garbage. To address pollution emanating from solid wastes, the DENR assists LGUs in the conversion of their open dumpsites into sanitary landfills and the establishment of materials recovery facilities.

Water Management

In years ahead, DENR will continue to improve water quality in priority rivers and water bodies. A comprehensive plan will be implemented to effect substantial improvement of water quality in rivers and other water bodies.

Manila Bay will be completely rid of all illegal fish pens, up to Bataan. More pressure will be placed on the water concessionaires in Metro Manila for them to accelerate their respective sewerage programs. These will solve the water pollution problem in the water bodies transecting and surrounding the megapolis.wastewater_treatment_2

The Pasig River will undergo massive dredging. Riverbank structures will be relocated. Informal settlers residing along the banks of the river will also be relocated.

Laguna Lake will complete dismantling of illegal fishpens. The carrying capacity study will serve as the basis for rationalizing the use of the lake.

Taal Lake will also be freed of illegal fishpens. A management plan for this lake will be developed on the basis of its carrying capacity study.

More stringent measures will be initiated to rehabilitate the Marilao River. Informal settlers along the periphery will be relocated and land and coastal zoning will be developed.

asbu_IEC2Information, Education and Communication (IEC)

The most effective way of ensuring the protection of our environment and sustainable management of our natural resources is to transform our people into stewards of the environment. This should be possible through awareness raising and environmental education.

The DENR is undertaking a massive and comprehensive information campaign using all forms of information media — tri-media, cyberspace, text messaging, etc. The campaign includes the development of documentaries and the use of primetime spots to reach a maximum number of people.

Environmental education in the school system and training programs will also be institutionalized to teach children of school age the value and benefits of environmental protection.


To build capacities, the DENR networks and maintains partnerships with non-government organizations and civil society. The Department also partners and maintains sound working relationships with the LGUs. Training and capacity-building programs are given to barangay officials and communities to heighten their awareness and knowledge of laws and regulations pertaining to the environment.

Law Enforcement

The DENR shall fully utilize the green legal army, the environmental ombudsmen and the green courts to increase rates in the detection, arrest, prosecution and conviction of violators of environmental laws, rules and regulations.

Regional Profile

Cagayan Valley Region has a distinct history.  Long before the coming of the Spaniards into the Valley, fishing villages had been in existence on the banks and at the mouth of the rivers and creeks flowing into the China Sea.  The Spaniards found natives inhabiting the narrow coastal plains of Northern Luzon and flood plains of Cagayan River. These inhabitants were Ibanags who lived on the riverbanks.  “Ban nag a native word for river.  They were of sturdy Indonesian type with a culture of their own.  They maintained their commercial relationship with China, Malaya, Japan and other neighboring countries,  The early Ibanagas kept their writings on barks of trees and bamboos depicting the heroic deeds of their chiefs.  These tales were used as songs and bards during the victories in wars, on weddings and other important events and were thereof handed down from generation to generation.It was in 1567 when Don Juan Salcedo explored Northern Luzon and landed his forces.  It was however in 1581 that the Spaniards headed by Captain Juan Pablo Carreon with his soldiers and their families settled in the Region.  Thereafter, Spanish missionaries gradually penetrated deeper into the valley teaching and converting the natives.  Later, the Americans improved the educational and political system and introduced improvements in infrastructure.Region 02 is considered the “last frontier” of the Philippines being one of the few regions with existing virgin forest.  It is bounded by three (3) mountain ranges, Sierra Madre on the east, Caraballo mountains on the south and Cordillera mountain on the west.Cagayan Valley Region includes all lands east of the Sierra Madre mountain,  west of the foothills of Cordillera mountain, and south of Caraballo mountain, making the region one big watershed area such that all the headwaters from the mountain ridges cascade down the tributaries to the Cagayan River, the second longest river in the country having a drainage area of 27,300 sq. km. and ground water reserve of 47,895 mcm.  The Cagayan River provides the water supply of the region for agriculture, industry, domestic and municipal needs before it drains into the Babuyan channel.  It has three major tributaries; the Elogan River which drains a major portion of the eastern watersheds, the Magat River which drains the southern portions and the Chico river which drains most of the north-western areas.The Pacific Ocean skirts the last coast and rest its waves on the foot of the Sierra Madre on the eastern side.  Temperature is distinctly tropical and the northern portion has a high precipitation due to the exposure of the northeastern air movements.  The region is composed of the distant but esoteric Batanes; the lustrous and fertile valley provinces of Cagayan, Isabela and Nueva Vizcaya and the predominantly mountainous but equally promising Quirino.  Cagayan Valley abounds with the natural resources and exudes the development potentials.  It consists of rich agricultural areas, forestlands and grasslands, inland and marine resources.By virtue of Executive Order No. 192 dated June 10, 1987, five (5)  Provincial Environment and Natural Resources Offices (PENROs) and sixteen (16) Community Environment and Natural Resources Offices (CENROs) were created under the administrative jurisdiction of Region 02. These are:  PENROs Batanes, Cagayan, Isabela, Quirino and Nueva Vizcaya; and CENROs Aparri, Alcala, Sanchez Mira, Solana and Tuguegarao, Cagayan; Cabagan, Naguilian, Cauayan, San Isidro, Roxas and Palanan, Isabela; Diffun and Nagtipunan, Quirino; and Bayombong, Aritao and Dupax, Nueva Vizcaya.



 Region 2 reactivates envi law enforcement group

2019 09 

The Armed Forces of the Philippines and the Philippine National Police (PNP) have agreed to include in their enforcement activities other environmental laws whenever requested by the Department of Environment and Natural Resources (DENR).

This agreement was made after DENR Cagayan Valley Chief Atty. Antonio A. Abawag solicited the assistance of these law enforcement agencies in the apprehension of illegal transport of mineral products during the Regional Anti-Illegal Logging Task Force (RAILTF) meeting held earlier at the DENR Regional Office in Tuguegarao City.

Director Abawag said the DENR will expand the deputation of ENR Officers to the members of the Task Force. They will be required to participate in the law enforcement training before their deputation.

The meeting resulted in the draft memorandum of agreement (MOA) reactivating the operationalization of the RAILTF. The MOA redefines the roles and obligations of the member agencies and the engagement of the Philippine Air Force, Philippine Navy and Philippine Coast Guard.

The MOA will provide quick response to verified reports of environmental violations within the region. It will also improve environmental law enforcement from deterrence, investigation, arrest and searches to prosecution.

The RAILTF was created in accordance with Resolution No. 2011-003 of the National Anti-Illegal Logging Task Force which defined the roles of the local government units and other law enforcement agencies.

The Task Force is mandated to take the lead in the anti-illegal logging campaign. It may call upon the support of any department, bureau and office to assist in the discharge of its functions, such as but not limited to the provision of administrative and technical assistance, logistical support and detail of personnel.

During the meeting, Atty. Abawag ordered the Provincial and Community Environment and Natural Resources Officers to closely coordinate with the battalion and unit commanders of the Philippine Army and the PNP in conducting anti-illegal logging operations. #CCC
