UPLB, DOST-NRCP present impacts of GMAP-Marinduque rehabilitation project, urge sustained bioremediation efforts

Research shows rehabilitation efforts in mining-affected areas of Marinduque provide measurable environmental and social gains, prompting experts to push for wider implementation and stronger policy support.

The findings came from the project “Impact Assessment of Greening Mined Areas in the Philippines (GMAP) Program,” funded by the Department of Science and Technology – National Research Council of the Philippines (DOST-NRCP) and implemented by the University of the Philippines Los Baños (UPLB). The assessment evaluated the outcomes of GMAP-Marinduque Phase 1, a separate NRCP-funded project titled “Bioremediation Strategies for Rehabilitation of Abandoned Mined Areas in Mogpog.”

The assessment results were presented during a stakeholders’ forum organized by UPLB in partnership with DOST-NRCP at Marinduque State University (MarSU) on March 19, 2026.

Environmental, social, institutional, and economic gains documented

Presenting the findings, Dr. Evaristo Niño T. Cando of the UPLB College of Human Ecology and member of the NRCP Social Sciences Division reported improvements in vegetation cover, air quality, and soil stability in treated areas. These changes contributed to reduced soil erosion and signaled gradual ecosystem recovery.

On the social front, communities reported fewer cases of respiratory and skin diseases, along with reduced spread of airborne illnesses. Environmental awareness also increased among residents. However, awareness levels varied across municipalities, indicating the need for broader and more inclusive community engagement, particularly in remote and vulnerable areas.

 

Institutionally, the study identified gaps in coordination among national and local agencies. It recommended integrating rehabilitation strategies into local land use and development plans to ensure continuity and policy support.

In terms of economic impact, the assessment projected a return on investment of about 730 percent over a 20-year period. Researchers noted that products derived from the project present potential livelihood opportunities but require technical support and sustained funding to benefit communities effectively.

Despite these gains, the study found that improvements remain largely confined to pilot sites. Researchers recommended expanding site-specific interventions across other affected areas in the province. The research further noted other areas for improvement, including the development of viable livelihood models, continuous monitoring of soil and water quality, and further research on bioremediation technologies. Ensuring community ownership of the program after project turnover was also identified as crucial to long-term sustainability.

Dr. Evaristo Niño T. Cando, Project Leader of “Impact Assessment of GMAP Program”, leads the presentation of results during the stakeholders’ forum held at the Marinduque State University (MarSU) on March 19, 2026.

Stakeholders support for sustained rehabilitation

Stakeholders from government, civil society, and academia expressed support for expanding the program and sustaining rehabilitation efforts.

The Provincial Environment and Natural Resources Office (PENRO) – Marinduque conveyed its continued support for sustaining and scaling up bioremediation initiatives in the province. It emphasized its readiness to extend technical and institutional support to ensure the continuity and long-term impact of similar environmental efforts.

The Marinduque Council for Environmental Concerns (MACEC) likewise reiterated its commitment to environment advocacy. “We have adopted the bioremediation technology for replication bilang tanda ng aming patuloy na commitment to bring back life to degraded land caused by mining,” Ms. Elizabeth Manggel, representative, shared.

Furthermore, MarSU Vice President for Research, Extension, and Training Dr. Ma. Edelwina M. Blasé highlighted the program’s role in opening opportunities for research and innovation in the province.

Stakeholders share insights and feedback following the presentation of the assessed impacts of the GMAP Project in Marinduque.

Findings confirmed that bioremediation effectively restores degraded lands, with stakeholders emphasizing the need for sustained investment, better coordination, and deeper community engagement.

Before the presentation, Dr. Nelly S. Aggangan, GMAP founder and member of the NRCP Division of Agriculture and Forestry, provided an overview of the program. She discussed how indigenous microorganisms, including arbuscular mycorrhizal fungi and nitrogen-fixing bacteria, can rehabilitate degraded ecosystems.

A post-forum workshop on biofertilizer application (BIO-N) was conducted to demonstrate how the GMAP’s products are applied and how these support plant growth. The session was facilitated by GMAP Technical Consultant Forester Julieta A. Anarna. (Rose Dagupen // S&T Media Services)
