Nature-based Solutions Strengthen Climate Resilience in Zamboanga City
ZAMBOANGA CITY ─ Momentum for environmental restoration is rising in Barangay Kasanyangan, where EARTH Champions and community representatives carried out another major mangrove rehabilitation and clean-up effort on November 30, 2025—further strengthening the barangay’s defenses against climate risks. The initiative advances ongoing community-led efforts to restore damaged ecosystems due to the relocated population affected by the Zamboanga Siege back in 2013.
This activity supports Zamboanga City’s Central Mangrove Management Plan, which prioritizes the protection and rehabilitation of coastal areas to enhance climate resilience, enrich biodiversity, and reduce exposure to flooding, storm surges, and tsunamis.
During the event, volunteers planted 1,500 mangrove propagules, helping stabilize the shoreline and improve habitat conditions for marine species.
Kali Halima, Monitoring Officer of Barangay Kasanyangan shared, “each tree we plant and every piece of trash we remove helps build a healthier, more sustainable future.”
In addition to planting, EARTH Champions collected 15 sacks of non-biodegradable waste—52 kilograms in total—from the mangrove roots and intertidal zone.

The activity demonstrated strong community stewardship and the growing commitment of residents to care for their environment.

Strengthening waste management through local action
A significant development under the EARTH Project in Zamboanga City is the improved system for waste collection in Kasanyangan and Rio Hondo. Initially, the city’s Office of the City Environment and Natural Resources (OCENR) supported waste collection during clean-up drives, but as city-wide clean-up operations intensified, regular collection at the EARTH project site became difficult to maintain.
Previously, the community relied on a smaller truck for waste collection. Recognizing this gap, the barangay local government unit of Kasanyangan purchased a solid waste dump truck to ensure consistent waste collection and prevent accumulated debris from returning to rehabilitated areas. It took an additional month to mobilize personnel, including a dedicated truck driver and waste collectors.
Volunteer mobilization has likewise grown significantly. Recent clean-up drives have gathered as many as 304 volunteers, including EARTH Champions, barangay officials, community members, and 4Ps beneficiaries. This expanded participation demonstrates how the EARTH Project has strengthened community ownership of waste management and environmental protection—ensuring that rehabilitation gains are not undermined by unmanaged solid waste. “By working together, we can make a meaningful impact one step at a time,” Kali added.

What are EARTH Champions?
A central focus of the EARTH Project is empowering community members to lead and sustain environmental initiatives. EARTH Champions are residents organized through the Community Savings Groups (CSGs), either established or supported by the project. While CSGs function as savings and resilience mechanisms, they also serve as platforms for environmental advocacy, enabling members to promote nature-based solutions at the barangay level.
Trained in solid waste management and environmental monitoring, the EARTH Champions are mobilizing their neighbors, supporting restoration activities, and championing responsible environmental practices. Throughout the course of the project, these champions will also be trained on mangrove nursery management and water conservation. Their leadership ensures that the project’s outcomes are community-driven, locally owned, and sustained beyond the project cycle.
Participation in the barangay’s mangrove enrichment and clean-up drive continues to expand. The latest effort saw more than 40 new EARTH Champions, alongside returning volunteers and barangay representatives. This growing engagement reflects the strengthening capacity of residents, who are not only contributing to restoration efforts but are also emerging as advocates for long-term environmental protection in their community.
Why these efforts matter
Beyond the numbers, these efforts are crucial because mangroves serve as natural barriers that protect coastal communities from storm surges, erosion, and flooding—hazards that are becoming more frequent due to climate change. By planting local mangrove species such as Bakauan Babae (Rhizophora mucronata), Bakauan Lalaki (Rhizophora apiculate) and Bangkauan Bato or Bangkaw (Rhizophora stylosa), volunteers are helping restore a vital ecosystem that supports marine biodiversity, and strengthens community livelihoods.
By removing waste and restoring degraded areas, EARTH Champions and community volunteers are not only protecting their coastline but also ensuring that future generations benefit from a more stable, productive, and climate-resilient environment. These activities show how small, consistent actions can collectively rebuild ecosystems that shield and sustain coastal communities.

About EARTH
The Environmental Actions for Resilience and Transformative Humanitarian Interventions (EARTH) project is a pilot initiative that integrates environmental safeguarding and restoration strategies into humanitarian action in the cities of Zamboanga and Malabon. Implemented by Action Against Hunger, CARE Philippines, and ACCORD, and funded by the EU Civil Protection and Humanitarian Aid, the two-year, community-led project strengthens urban resilience through people-centered, multisectoral, nature-based solutions.
EARTH promotes a nature-based solution model that integrates mangrove reforestation, solid waste management, water conservation, and sustainable livelihoods—reducing environmental risks while restoring vital ecosystems.
