Hydrological Impact and Siltation
The most visible manifestation of mining pressure on Mount Diwata is the alteration of local hydrology, specifically concerning the Naboc River. Extensive excavation and the removal of topsoil have led to significant siltation of the river system. Sediment loads from the mountain slopes wash into the Naboc River, increasing turbidity and altering the riverbed’s composition. This siltation affects aquatic habitats, reducing the clarity of the water and impacting the species that depend on the river for survival. The Naboc River serves as a critical water source for downstream communities and agricultural lands in Davao de Oro and Davao Oriental; therefore, the degradation of its quality has direct implications for water security and local agriculture. The continuous influx of sediment also increases the risk of flooding during the wet season, as the river’s capacity to hold water is diminished by accumulated debris and soil.
Mercury Poisoning and Human Health
A critical public health concern associated with the mining activities on Mount Diwata is mercury poisoning. In many informal gold mining operations, mercury is used as a primary reagent to extract gold from ore through the process of amalgamation. When not managed with rigorous technical controls, mercury is often released directly into the environment, entering the soil and the water systems, including the Naboc River. Local miners, who frequently have direct skin contact with the amalgam and inhale mercury vapors during the heating process, are at high risk of acute and chronic mercury exposure. This contamination also extends to the local population through the consumption of fish from the silted rivers and crops irrigated with contaminated water. The bioaccumulation of mercury in the food chain poses a long-term neurological risk to the communities in Monkayo, Cateel, and Boston, creating a public health crisis that parallels the ecological damage.
Risks to Flora, Fauna, and Biodiversity
Mount Diwata is recognized as a biodiversity area, hosting a variety of flora and fauna that are adapted to the mountainous terrain of eastern Mindanao. The expansion of mining claims and the physical disruption of the landscape threaten these biological resources. Deforestation associated with mining operations reduces the canopy cover, leading to habitat fragmentation for local wildlife. The introduction of heavy metals, such as copper and mercury, into the soil and water systems creates toxic environments for sensitive plant species and aquatic life. The remote nature of the mountain, while offering some protection from urban sprawl, has also made regulatory enforcement challenging, allowing environmental impacts to accumulate over time. The loss of biodiversity on Mount Diwata represents a significant reduction in the ecological resilience of the Davao Region, affecting everything from pollinator populations to larger vertebrate species that rely on the mountain’s forests for shelter and food sources.
