Through these programs, First Gen is able to protect and conserve marine and forest areas, while providing livelihood opportunities to local communities.

Habitats protected or restored

Center of the Center

Way back in 2004, First Gen has been implementing the Center of the Center, a marine conservation program, covering 101.93 hectares located in Verde Island Pass, Batangas. The program, in partnership with the Batangas Provincial Government – Environment and Natural Resources Office, and ABS CBN Lingkod Kapamilya, supports the Bantay Dagat (sea watch volunteers) in the Province of Batangas in their conduct of marine law enforcement in their respective municipal waters. In 2016, First Gen provided operational support to the Bantay Dagat from the Municipalities of Tingloy and Lobo while assistance in livelihood program was accorded to the Bantay Dagat in the Municipality of Mabini.

The program has also strengthened capability building and awareness, and granted incentives that resulted to:

  • 348 Bantay-Dagat members provided with capability-building
  • Insurance Protection of 35 marine protected areas covering 1,554 hectares in the Province of Batangas
  • 29 Bantay Dagat provided with operational support and incentive
  • 60 students from Malabrigo Elementary School and Malabrigo National High School completed the Marine Information, Education Campaign (IEC)
  • 14 employees completed the Facilitators’ Training for Marine IEC and 37 Head Office and Site Office employees participated in the marine IEC

BINHI Forest Restoration

BINHI is the nationwide greening program of the Energy Development Corporation (EDC). Its aim is to restore denuded forests, preserve and propagate threatened native tree species, and protect biodiversity to leave a legacy of a verdant Philippines for the next generation. It covers its geothermal project sites: Albay and Sorsogon; Leyte; Negros Oriental and Negros Occidental; and North Cotabato and Davao del Sur as well as the non-geothermal areas (Pantabangan, Nueva Ecija; Ilagan, Isabela; and Burgos/Solsona, Ilocos Norte), and the Frontier Areas (Misamis Occidental, Camarines Norte, Misamis Oriental, Davao del Sur.) The partnership of EDC with various farmer associations in the various EDC sites, led to the reforestation of 9,449 hectares of watershed areas in its project areas and other areas outside of the company’s operations from 2009 to 2019.

In 2019, 30 hectares of lands in BacMan and Mt Apo Geothermal Projects and 70 hectares of grasslands in Pantabangan-Masiway Hydro Power Project were planted with indigenous forest and fruit trees. Also, 2,000 hectares of existing BINHI plantations across EDC project sites were protected and maintained.

Forest Protection

Forest Protection entails all EDC initiatives to protect the forests and watershed areas inside the geothermal reservations where the company operates. This includes forest patrol and enforcement of forestry laws, forest fire management and control and IEC with communities in its geothermal project sites: Albay and Sorsogon, Leyte; Negros Oriental and Negros Occidental; and North Cotabato and Davao del Sur.

In partnership with the Department of Environment and Natural Resources (DENR), Armed Forces of the Philippines (AFP), Philippine National Police (PNP), Local Government Units and people’s organizations, a total of 34,770 hectares of watershed areas within the development blocks and identified conservation areas across geothermal project sites were prioritized for forest patrolling using the Lawin System, a technology-based forest and biodiversity protection system that uses smartphones to capture patrol data on biodiversity and threats and open-source technology for geo-spatial analysis.

In 2019, EDC, DENR, and other partners conducted more than 600 patrols across the four geothermal reservations, resulting in six apprehensions and confiscations of illegal forest products. EDC also provided around 400 man-hours of training for its community volunteers and partner agencies (AFP, PNP) on forest law enforcement, Lawin patrolling, forest fire prevention and response, and other aspects of forest protection. The Company also supported Information, Education and Communication (IEC) campaigns to increase awareness of local communities on the importance of forests and biodiversity, and environmental laws.
