Ecosystems Research and Development Bureau


San Fernando City, La Union



MISSION  Ourmission is to provide relevant WATER AND WATERSHED RESOURCES technology and information through research towards sustainability and enhanced productivity of the natural resources and protection of the environment for the improvement of the quality of life of the Filipino people



The Rationalization Plan of the DENR called for the creation of the Watershed and Water Resources Research Center (WWRRC) under the auspices of the Ecosystems Research and Development Bureau. It was created by merging the Research Service of four (4) DENR Regional Offices of Regions 1, 2, 3 and the Cordillera Administrative Region. WWRRC is based in the former DENR-ERDS Office in Loakan, Baguio City with its Research Stations located in the three regions. 

Consistent with the DENR’s mandate to be the driving force in the pursuit of sustainable development, and in enabling stakeholder participation in the conservation, protection and rehabilitation of the Region’s environment and natural resources, the Region 1 Ecosystems Research Station (R1ERS) is committed to develop ENR research and development technologies on water and watershed resources of Region 1. Moreover, the Station is also the frontline for the extension of sustainable water and watershed resources technologies to the various stakeholder publics.


Region 1 has 22 priority watersheds and 13 sub-watersheds in the four provinces of the Region. The priority watersheds of Region 1 cover an approximate area of 906,178.12 hectares. Seven (7) of the 22 Priority Watersheds in the Region are found in Ilocos Norte; Six (6) are in Ilocos Sur; four (4) are in La Union, (including Amburayan River Watershed which is shared by both the provinces of La Union and Ilocos Sur); and six (6) in Pangasinan. The following tables list the priority watersheds in the Region:

In support of DENR’s primary mandate, six (6) studies and two (2) programs are currently being implemented by the R1ERS. The six studies are cascaded components of the national watershed program funded and initiated by the ERDB through the WWRRC. The following table lists the studies being conducted in the Region:

            The implementation of R & D and TTES during the first semester of 2015 was wrought with challenges brought about birth pains of an organization that is under transition towards a rationalized structure. There were no clear and concise manual of approvals and authority for the Center operations resulting in logistical bottlenecks in the implementation of the R & D and TTES activities.

            Despite these constraints, best efforts were exerted by the staff under the guidance of the Acting Director of the WWRRC. Series of levelling off workshops were undertaken to explain and discuss the R & D and TTES programs to be pursued by the Center and tasks were assigned to the various personnel to ensure that the program targets will be accomplished.


The R & D studies conducted were highlighted by the following:     

1. Hazard Analysis of Sta. Maria Watershed


Vegetational assessment of riparian area of Sta. Maria Watershed in San Emilio, Ilocos  


 Water quality monitoring of Cabaroan River in San Emilio, Ilocos Sur


2. Phytoremediation of Parongking River In Pangasinan

            The fundamental challenge of the TTES program of the WWRRC is how to bring to the fold of sustainable water and watershed resources management the various target stakeholder publics of the technologies generated by the ERDS/ERDB. For the first semester of 2015, the strategy employed included the following: strengthening of previously established technology demonstration areas; “piggy-backing strategy” in the conduct of activities; and stakeholder analyses to determine entry points for technology extension services.


Maintenance of Established Techno Demo Sites


            Coaching on the established Poles Per Year Bamboo Harvesting Technology Demo Site was done to strengthen technology adoption by cooperators in Barangay Abut, San Fernando City, La Union. 


 To encourage more adopters of the Bamboo PoPeYe Technology, a cross-visit of bamboo technology cooperators from Barangay Cabarsican (also in San Fernando City, La Union) to Barangay Abut PoPeYe Demo Area was organized to orient them on sustainable way of harvesting bamboo poles



Techno Forum, Media Conference, Exhibit

            Using the piggy-backing strategy, the TTES targets for the 1st and 2nd Quarter were conducted in conjunction with DENR Regional Office 1 activities, specifically the Gender and Development activities during the Women’s Month Celebration. It made possible the implementation of targets despite the resource constraints. The mature Bamboo Technologies generated by the ERDS/ERDB were presented in the Technology Forum on Sustainable ENR livelihood technologies organized by TTES in tandem with the DENR Regional Office 1 Gender and Development activity for the Women’s Month Celebration. The National Greening Program People’s Organizations all over the region were the target audiences for the dissemination of Bamboo Technologies which are relevant to the bamboo-rich Ilocos Region. To encourage stakeholder empowerment in the rehabilitation efforts in the watershed areas, they were given participation spaces in the Technology Forum, media Conference, and in the Livelihood Exhibits where they were able to sell their products. 




Conduct of Stakeholder Analysis

Stakeholder analysis was done to determine ENR technology needs of the target clients. Before ENR technologies are packaged and disseminated, this activity was done to determine the entry points for technology extension services.

During the Bamboo Techno Forum, a stakeholder analysis was conducted to determine their technology needs. During the Techno Forum, one of the needs identified is the lack of access to financial resources for ENR investment projects. In response to the need, the TTES organized an ENR Investment forum for Sto. Domingo, Ilocos Sur and Lidlidda, Ilocos Sur where the Small Business Corporation, an attached office of the Department of Trade and Industry, was invited to assist the people’s organization and the LGU in accessing financing resources for their ENR projects.The Investment Meeting conducted for the LGUs of Sto. Domingo and Lidlidda, Ilocos Sur resulted in the initial identification of ENR programs to be enrolled by said LGUs in the Small Business Corporation Financing Programs.


Production of IEC Materials

            Fact sheets, ENR Fans and  Comics were drafted as IEC materials for the dissemination of Technology Information, Product and Process. The drafted IEC materials underwent pre-testing before production



                        To complement the watershed rehabilitation, reforestation efforts and programs of the DENR and other stakeholder partners, four (4) nursery facilities were established and maintained to produce quality planting materials. Likewise, an experimental forest was also maintained in Tadao, Pasuquin, Ilocos Norte. The PFDPIN Experimental forest covers an area of 3,867 hectares. The following table shows the nursery facilities in of WWRRC-R1ERS.
